TV how to choose, choose traditional LCD or OLED, which brand is better?
How to choose a TV, opinions vary, see the wisdom. Therefore, it can only be a personal opinion, just for reference. Choose TV, mainly consider the following aspects:
One, budget. It seems that few people feel that this is a factor, but this aspect is really important. If it is only want to spend a three or two thousand or less, but also want to buy a 50 or 60 inches of large TV, then buy LED LCD TV, brand selection of domestic or joint venture, low-end products can be.
Second, the size. Generally depending on the viewing distance, three meters five or less, 55 inches on the line; four meters or less, 65 inches can be; more than four meters, 75, 85 inches can be. Of course, like a big screen, on this basis, increase a grade, is not inevitable.
Third, the type. At present, the technology is more mature type of TV has LED TV, OLED TV, laser projection TV and QLED TV (essentially with LED can be categorized as the same class), etc., LED TV with its long time on the market and the advantage of low prices accounted for most of the share of the other types of TV is still a niche. The pursuit of display effect, OLED TV is the best; if you like the super large screen, laser projection is the best choice; look at the cost-effective, choose LED TV.
Fourth, the brand. TV brands are many and varied, but mainly domestic brands and Japanese and Korean brands. To 65 inches to 75 inches, for example, if the budget is not much, it is recommended to choose the domestic mid-range or imported (joint venture) low-end LED TV; if the budget is five thousand to ten thousand, you can choose the domestic high-end or imported high-end LED; 10,000 to 15,000, you can choose the imported high-end brand LED and mid-range OLED TV; 15,000, 20,000 or more, imported high-end OLED TV. Specific brands, LED TV, domestic Hisense, Haier, Skyworth, Changhong, TCL, millet, etc. can be, Japan and South Korea brands are mainly Sony, Panasonic, Samsung, LG, OLED TV, Sony, Samsung is good, the national brand has Skyworth, laser projection TV can choose Hisense.
The above is for reference only.
Want to change a good high-pressure TV, but in the end to buy what kind of TV is still confused, especially in the choice of traditional LCD TV (LCD) or OLED TV on the more doubtful. So OLED TV in the end where good, we in the end there is no need to spend more money on these new technologies? Then I will analyze from 1. material, 2. appearance, 3. color, 4. brightness, 5. response time, 6. viewing angle, 7. size, 8. price and other technical dimensions one by one, the purpose is to let everyone really understand what their needs are, when shopping to make the most suitable for their own decisions.
1, the two in the construction of the specific what is the difference
Although many people seem to have a clear perception of the differences between the two technologies LCD and OLED, but the difference between the two technologies is not as simple as it seems.
First of all, we need to know that these two are two completely different display technologies, and there is a fundamental difference in the light-emitting principle.
Literally, LCD (Liquid Crystal Display) is the "Liquid Crystal Display" technology, which uses LEDs (light-emitting diodes) as the backlighting source for TVs, which is often referred to as LCD TVs.
And OLED (Organic Light-Emitting Diode), literally "organic light-emitting diode", it can "self-illumination", does not require a "backlight". "
With the new technology, you will be able to see the light from the back of the screen.
Some industry insiders on the difference between OLED and LCD made a very graphic analogy: OLED is like the sun, because all the pixels are like a small bulb, can be "self-luminous", so no matter from which angle you look at it is bright; LCD is more like the moon, because it needs The LCD is more like the moon, because it needs a backlight panel behind the screen as an auxiliary light source to illuminate the display by reflecting and refracting light.
2, the two in the appearance of the different
Relatively speaking, the structure of the LCD panel is more complex, so it is difficult to achieve the thickness of the panel is very thin, so many businesses in the investment in the huge investment, in order to make the screen as thin as 0.1mm. OLED display technology does not require the support of the backlight, eliminating the need for liquid crystal and backlighting module, the structure of the simpler, the body can naturally reach the extreme. The body of the natural can reach the ultimate ultra-thin, about 1/3 of the thickness of the traditional LCD, and can even make the TV like paper, the TV into a "work of art" to put.
In addition, OLED's flexible and bendable nature allows it to be made into a curved screen and other shaped screens, with no color casts or distortions on the display, which is unthinkable in the LCD era.
3. How is the picture quality performance brought by OLED?
In terms of color, OLED panels, because they are self-illuminated, display colors that are closer to the real world, especially their black field performance (or black level), which means that when displaying a black scene, it is possible to turn off the pixels without illuminating them, so it is truly black. And LCD in the display of black, the backplane is still in the black color light out, so even if the masking effect is now done very well, almost all LCD TVs, in the display of black scenes still have light leakage phenomenon.
From the color gamut, OLED's color gamut coverage value is also relatively high, NTSC is generally around 95%, which can provide nearly perfect natural colors.
In terms of brightness and contrast, OLEDs are self-illuminated, and because of their excellent black field performance, their contrast ratio is close to infinite, and they can still be displayed clearly in sunlight. And with a viewing angle of up to 178 without distortion, you can enjoy an outstanding picture no matter what angle you look at. This is especially important for those who love to watch sports and play games on TV.
4. How big can an OLED TV be?
The OLED TVs on the market now, due to their high-end positioning, are hard to see screens below 50 inches, and are most commonly found in the 55" to 65" range, which means that in terms of the size of the current mainstream TVs, OLED TVs are not weak at all. From the product yield, 55-inch and 65-inch OLED panel yield has reached more than 90%, the service life has reached 50,000 hours, and can be used in parallel with LCD panels.
5, OLED TV price geometry?
As the latest display technology OLED TV, its price also exists in the new technology to bring a high premium. Generally speaking, the current market mainstream OLED TV price is 2 to 5 times the mainstream LCD TV, can be said to be worth a lot. Of course, the high price and new technology accompanied by good picture quality.
However, due to the rapid progress of OLED production technology, its yield and production capacity is also greatly improved, it can be predicted that, with more and more brands launching OLED TVs, in the next two to three years, the OLED TV selling price will certainly continue to decline. And this seedling has begun to appear: in the middle of this year Philips listed a 55-inch OLED783 TV, despite the application of Philips' patented technology P5 picture engine, its price is still not more than 8000 yuan. For many people who want to experience OLED high picture quality, this is a piece of good news.
Comprehensive the above points, OLED TV is not as bad as rumored, want to good picture quality and not very bad money, you can choose OLED TV.
In the broad sense of the OLED TV effect is better than the traditional LCD TV effect, such as pixel-level light control, wide viewing angle, high color gamut, fast dynamic response, infinite contrast and many other advantages. For the average user, choosing OLED over LCD will have a better viewing experience.
But for enthusiasts, OLED still has a few drawbacks,
such as "burn-in", "dirty screen", too low brightness
What is "burn-in"?
What is "burn-in"?
Burning screen refers to a long time to display a static image screen, leaving a mark of the phenomenon, this is because OLED display technology is different from the traditional LCD, he does not need a backlight, the use of very thin organic material coating and glass substrate, when there is a current through the organic material, these organic materials will be luminous, these organic materials exist in the life of the material, with the increase in the use of time and heat slowly degradation of aging, a fixed position always show the same picture for a long time.
Although manufacturers now publicize that they have solved the problem of "burn-in", it is actually impossible, just pixel shifting and ABL (brightness limitation) to extend the life of the screen, but there will be a day when you will be able to do so.
In addition, the dark part of the OLED TV will have a dirty screen problem, because the dark part of the voltage will be unstable, resulting in the black part looks dirty, and the dark part of the gray scale has a problem, below a certain degree of gray scale, can only be displayed as pure black, resulting in the dark part of a dead black, the lack of dark details.
There are also OLED TVs that are inherently less bright than LCD TVs, plus the ABL mechanism, which makes it difficult to brighten up the picture, which can lead to very high bursts of highlights when we're watching HDR video.
Of course, traditional LCD is not perfect, there are many problems, such as HDR backlighting is easy to produce halo, the dynamics of the poorer, the picture compared to OLED appears to be more gray and so on
Then how should we choose? In fact, according to the display characteristics of the two just mentioned, OLED is recommended to use in a dimmer room, can reflect the greater advantage, while in the open living room, it is recommended to choose traditional LCD.
Traditional LCD TVs and OLED TVs have their own advantages. Traditional LCD TVs (i.e., LED/LCD TVs) use backlighting for imaging, and if the technology is mature, you can achieve a great color display by doing zonal backlighting. For example, Samsung and Sony are still launching new LED TVs, which means that LED TVs still have their own market.
But OLED is, after all, one of the next generation of display technology, whether from the color rendering, energy saving, ductility, environmental protection, etc. Compared to LED has a very big advantage, if you do not consider the price factor, or more recommended OLED TVs, Sony, LG, Xiaomi and other manufacturers, whether foreign or domestic have launched their own OLED flagship TV products, which indicates that OLED has been ready for mass production and applicable to the family, we do not have to worry about the immaturity of the technology.
Therefore, one sentence summarizes: limited budget can choose the best LCD TV within the budget; do not consider the price to buy OLED TV.
About the brand, foreign Toshiba, Samsung, Sony, etc., domestic TCL, Hisense, Skyworth, millet, Huawei, OPPO are good choices.
Whether it's a traditional LCD TV or an OLED TV, it displays 25 frames per second.The reason why we see the picture of the TV is moving is due to the phenomenon of "visual retention" of the human eye, the visualization produced by the light on the retina, after the light stops working, it will still be retained for a period of time. This is the basis for the formation and dissemination of visual media such as animation, television and movies. Continuous image changes over 24 frames per second or more, the human eye can not recognize a single static picture, it looks like a continuous smooth visual effect, such a continuous picture is video.
When you zoom in on a black-and-white picture, you realize that the picture is made up of small squares, which are pixels. In binary, these pixels are either "0" or "1". And so on, the more binary digits a single pixel has, the more colorful it can be. When a pixel point is 8 binary bits, there are 256 colors that can be displayed for each pixel point in this image.
How are the colors displayed?
If you look at the screen with a microscope you will see that each pixel point is made up of 3 sub-color pixels, red, green, and blue. A very wide range of colors can be modulated by adjusting the brightness of the red, green, and blue sub-color pixels.
Both LCD screens and OLED screens modulate the ratio of red, green, and blue primary colors to produce a colorful display.
What causes the difference between LCD screens, OLED screens appearance, black field performance, brightness, response time, viewing angle, price and many other dimensions?LCD, OLED screen although the principle of achieving color is the same, but they are two completely different display technologies, the two in the light-emitting principle of the existence of essential differences, resulting in two kinds of TV in the display as well as the form of a big difference.
LCDs rely on a backlight panel as their light source
The backlight panel only displays white, and the screen displays different colors because the LCD panel is selectively filtered for the backlight, controlling the amount of backlighting to achieve the purpose of displaying different colors.
OLEDs have self-luminous red, green, and blue sub-pixels for each pixel.
The full name of OLED is Organic Light-Emitting Diode, so OLED screens do not require a backlight module, and naturally they do not require a liquid crystal module. Compared to LCD, OLED's structure is much simpler and can be extremely thin, for example, OLED TVs can be about 1/3 the thickness of traditional LCD TVs, or even thinner, so thin that they can be curved and rolled up to be stowed away in a box and completely hidden.
In terms of form, OLED screens can be considered a big win. But many of the guys still want to see LCD, OLED nuanced performance.
Because of the self-illuminated nature of OLED, its black field performance is excellent. every pixel point of OLED can be extinguished to show the black; and LCD can not, the backlight will light up the whole screen, the liquid crystal components can not do a little bit of light also do not come out to show the black, so the black of the LCD feels like a gray.
Black field performance can determine the level of contrast, the blacker the black, the higher the contrast, so we will always feel the OLED screen will be more colorful.
LCD backlighting is not to say that it is very LOW, the backlight can be adjusted brightness access is very large, so LCD TV brightness can be very high. With the addition of quantum dots, it can be made even brighter. oLED pixel points can affect its lifespan if it is raised to a very high level for a long time.
OLED TVs perform better in dark rooms, while LCD TVs perform better in brighter environments. We would like to advise all of you to never, ever watch TV or cell phones in a very dark place. Long-term eye use in dim light will cause the pupil to grow for a long time, blocking the circulation of fluids in the eye, which will easily lead to the occurrence of glaucoma. The low contrast sensitivity of the eyes in the dark can cause the burden on the eye's adjustment system to increase, which can further lead to myopia deepening.
LCD in the light and dark shift, must be deflected liquid crystal molecules, the driver chip instruction to change the process requires a response time, so the LCD screen image will always appear motion blur, residual shadow phenomenon.
OLED as pixels can be directly to the dark and light transition, the naked eye almost imperceptible phenomenon of residual shadow, high-speed movement of the screen will be relatively smooth. So OLED TVs are far superior to LCD TVs in terms of corresponding speed.
The best viewing angle for LCDs is right in the middle, and image quality decreases at other angles. This is because the light source to provide LCD display after refraction and reflection of the output has a certain direction, beyond a certain range of color distortion will occur, although IPS and other technologies to improve the LCD viewing angle of the problem, but still less than OLED, OLED TV in different angles to show the picture is basically the same.
SummaryThe answer is already out there, OLED TV, whether from energy efficiency, or from the speed of response, brightness, contrast, viewing angle, etc. are better than the "predecessor" LCD TV, but LCD TV cheap ah. OLED TV will still face a lot of challenges in the future, because it also has a lot of its own shortcomings.
These are my personal opinions, and I welcome any criticism.
75 inches above the choice of LCD, 75 inches below the choice of OLED, if not bad money can also choose 88 inches OLED. If you're looking for the best value for money, you can go for the 88" OLED.
Last week, we decorated Mr. Lee's home almost, beds and furniture were moved in. The next step is to install the appliances.
On the choice of TV, Mr. Lee also asked the same question. What exactly is the best way to choose a TV?
I gave Mr. Lee an idea.
First, determine the size of the TV according to the living room.So that you know the specifications of the TV in harmony with their living room. I provided him with a copy of the China Electronic Video Association's "New Standard Table for Color TV Purchase Size".
According to the above table, Mr. Li's living room is 3.6m wide, so he needs to install a 75-inch 4K TV.
Second, refer to the size of the TV. Initially determine a budget.
Mr. Lee purchased a TV budget of $5,000-10,000.
Third, is based on this budget to filter which type of TV.
$5,000-10,000 basically identifies LCD TVs, and you can rule out OLED TVs, because mid-range OLED TVs are as low as fifteen thousand.
Four, take advantage of the "May Day" business activities, we accompanied him to the home appliance mall.
Found the boss, explaining that we decorate the company intends to purchase a LCD 75-inch 4K TV, the boss recommended to us a few recent sales of better TV sets.
As you can see from the table above, the Samsung UA75TU8000 and the Toshiba 75M540F should be excluded first, neither the hardware nor the performance has any advantage.
And the TCL 75 Q10 is just a higher value, the other thing that says it all is that it comes with Anbridge audio and supports Dolby Vision and Dolby Atmos. The best of these is the Thunderbird 75R635C.
This is a very cost-effective HDR TV, whether it is in terms of picture quality, or hardware performance is very good, the sound quality is also an immersive feeling, and the software optimization problems, now optimized has been very good.
I recommend that Mr. Lee get the strongest of these Thunderbird. Mr. Lee is also interested in this TV, asked the price, usually 8500 yuan, now the event price of 8000 yuan.
Then we examined the quality of the TV in 3 ways.
1, high contrast
Only high contrast can make the black bit reproduction, if the contrast is low, the original black bit will become gray, the image will become flat and lack of realism.
It's easy to look at the contrast when you buy a TV, because the cheaper TVs have a yellowish display when there is no signal on the screen, and the more expensive ones are darker and have higher contrast.
You can see if the picture is dark enough when there is no picture input. To judge the quality.
2, clarity should be good.
In fact, the clarity should be divided into static clarity and dynamic clarity, the former is mainly affected by the resolution, contrast and other factors, the latter is mainly affected by the time.
In the implemented HD standards, the "image clarity (static) motion picture trailing time" to assess the performance of the TV's clarity, the shorter the better, generally up to 20 milliseconds or so, even if it is good.
3. Is there a bad spot on the screen?
Look carefully at the screen to see if there are bright spots and dark spots on the screen, picking the LCD TV when the screen is set to all green and all blue, looking for dark spots in the all-green screen, looking for bright spots in the all-blue screen.
Once there is a bright spot or a dark spot is very easy to see, if not, it shows that there is no screen bad spot.
We picked a relatively good performance of the TV, and to the boss that our company will be with him in the future and long-term cooperation, the last 7500 yuan to take, Mr. Lee is very satisfied, happy to say: "I did not expect to get into the hands of cost-effective so high TV, the price of the hands than my budget is still low, worth it! "
V. Conclusion:
This is the whole process of purchasing a TV set, I hope that the purchasing ideas and quality grasp on your inspiration.
Traditional liquid crystals, generally known as LCDs, and OLEDs are completely different devices from LEDs. It is an organic light-emitting diode. The two light-emitting principle is different, LCD mainly rely on the backlight layer of light-emitting, while OLED is self-luminous.
Compared to traditional LCD TVs, OLED TVs have many advantages:
1, thin thickness: light weight, good anti-vibration performance: its structure is solid, it will not be easy to crack, scratch phenomenon.
2, good viewing angle: the viewing angle of this TV set is extremely good, the viewer sits in the left and right angle of the place, will not produce visual distortion distortion phenomenon.
3, fast response time: the TV set boot, change the response time is extremely agile, the TV set in the display of the "motion picture", there is absolutely no shadow phenomenon. Bring excellent viewing experience. As you can see, LOED screen TV has outstanding advantages. However, it is also expensive, much higher than the price of traditional LCD TVs of the same size.
Also, imported LOED TVs are again much higher than domestic ones. Consumers can make the right choice according to their respective budgets.
OLED benefits are good color reproduction, but the use of the family does not reflect, unless you have two at the same time to compare, the disadvantage is that the price is high, high power consumption, short life. LCD screen are currently good, but the same size do not choose the price is too low, the price is worth every penny, too high some features can not be used.
OLED TV does not need a backlight, the use of self-luminous mode, so the corresponding speed faster, wider viewing angle, basically no light leakage, picture clarity performance is better, very thin and light, relatively low power consumption, due to the use of organic materials OLED light-emitting, so the service life is not as good as half of the LCD TVs, but also expensive, color purity compared to the LCD TVs there is a gap, the OLED TVs have a lot to offer, but the OLED TVs have a lot to offer. It should be said that OLED TV in terms of technical maturity is not very high. The traditional LCD TV technology maturity is very high, the price is lower than the OLED, although in the response speed, contrast, viewing angle and so on and oled have a certain gap, but the gap is not very big, and the latest miniLED TV and oled TV basically no big difference. So the current choice of TV, it is recommended to give priority to the choice of traditional LCD TV, recommended to choose Huawei, Hisense, Philips and other large manufacturers of TV products, in the sound, picture quality performance, system smoothness and expand the function of the performance is better. If you like to taste, you can also consider Xiaomi TV 6 OLED, the cost performance is quite high. Here is a brief introduction to a few of the better LCD TVs and LED TVs.
Huawei Wisdom Screen V55Huawei Wisdom Screen V55 adopts a 55-inch 4K 92% DCI-P3 high color gamut screen, supports 120HZ high refresh rate, adopts a 16-partitioned backlighting system, with a maximum brightness of 750nit, which is already illegally close to that of the Xiaomi Mi 6 OLED Smart TV, and with its own Hongqiao chip and Hongmeng system, it delivers excellent HDR ViVID Hongbao picture quality, Huawei Smart Screen V55 adopts Deware 75W high-power audio system, the overall sound quality and picture quality performance is excellent, thanks to Huawei's own Hongmeng system and the depth of the Hongbao chip optimization, in terms of system smoothness is better than the ordinary Android TV one step. In addition, Huawei Wisdom Screen V55 adopts a 24 million AI Wisdom Eye camera, which supports AI fitness, video calls and other functions, and supports Huawei Hongmeng distributed cross-screen function, and the expansion function is also very good. Huawei wisdom screen although the LCD panel, but relying on the Huawei Hongmeng system and Hongbao chip joint picture quality enhancement engine, the picture quality performance is still very good, the current Huawei wisdom screen V55 Jingdong price of 5,499 yuan, cost-effective is still good, you can consider getting it.
Huawei Wisdom Screen V75 Super MiniLEDHuawei Wisdom Screen V75 Super MiniLED is Huawei's first MiniLED Wisdom Screen, using 46080 MiniLEDs, 2880 physical partitions, the highest brightness of up to 3000nitgs, with its own Hongmeng system and Hongbao Chip picture quality enhancement engine, in the overall Picture quality performance is not at all inferior to mainstream OLED TVs in the market, Huawei Wisdom Screen V75 Super MiniLED adopts the Diwalay 20-unit sound system, which supports the formation of a distributed speaker system with Huawei Smart Speaker, and the overall sound quality performance is very good. Huawei Wisdom Screen V75 Super MiniLED also adopts a 24 million AI Wisdom Eye camera, relying on Hongmeng's powerful distributed capabilities, the overall expansion ability is very powerful. It should be said that Huawei Wisdom Screen V75 Super MiniLED, relying on the powerful MiniLED backlighting system, as well as Huawei Hongmeng and Hongbao picture quality enhancement engine, the picture quality is fully comparable to the mainstream OLED TVs in the market, and the price is more favorable. If for the picture quality requirements are very high, choose LCD TV, Huawei Smart Screen V75 Super MiniLED is undoubtedly a better choice.
Xiaomi TV 6 OLEDOverall traditional LCD TVs and OLED TVs have their own advantages, LCD TVs have a very high degree of technological maturity, relatively cost-effective, and OLEDs have a greater advantage in terms of responsiveness, contrast, viewing angle, etc., but the price is higher, and the degree of technological maturity is not as good as LCD TVs. In addition to choosing a smart TV in addition to considering the picture quality, but also consider the sound quality, system smoothness, expanding functionality, etc., so if the recommendation, I personally prefer the traditional LCD TV, if you just consider the taste, OLED TV is also can be considered.
