Sharing the pros and cons of three different types of TVs

The first is the size and weight. Due to the weight and size of the CRT tube, CRT displays are limited to 40 inches or more, so CRT TVs on the market are only up to 34 inches, and not many people can fit more than 34 inches of CRT TVs in their living rooms. Despite the recent progress of spherical CRTs to flat screen CRTs, there is not much difference between the size and weight of CRT TVs.

The second is the issue of image stability and detail. Because CRT is a scanning method, using the principle of human vision to form an image, although human vision can not be seen, but look at a long time on the visual aspects of visual fatigue, and the use of scanning line imaging, it is difficult to present a detailed picture.

Third, and most criticized, is the problem of radiation. Because CRT monitors use electron guns to shoot out electron beams, there is the problem of radiation. Long-term exposure to a small amount of radiation, more or less on the human body will have an impact, parents want us to watch TV to keep a distance is not unreasonable. The European Union and the United States California *** based on environmental considerations, has announced that it will gradually ban CRT computer monitors, in the visible future, CRT TV will inevitably step on the same fate.

Advantages of LCD TVs

One, LCD TVs use a backlight module to emit light, basically, the service life of up to 100,000 hours or more, and the damage rate of the LCD panel is low, and the cost of consumables is also low (only need to replace the backlight module).

Second, the radiation is divided into electric field radiation and electromagnetic radiation, because LCD monitors and traditional monitors display principle is very different, regardless of which form of radiation is much lower than the intensity of traditional monitors. For parents worried about radiation, LCD TVs are the best solution for traditional TV radiation.

Disadvantages of LCD TVs

On the other hand, LCD TVs have the advantage of being able to show the true color of black, and the darker the color, the less contrasting the shadows are.

Second, the drag problem, also known as the reaction time, although less obvious in the small size of the LCD screen, but once enlarged to the LCD TV, it is easier to produce drag, especially when showing fast action movie more obvious.

Third, the panel of bright and dark points of the problem, LCD TVs, each point of light has a separate crystal to control the strength of its current, if the point of the crystal is broken, it will cause the point of light forever light (bright) or not bright (dark), and the color of the point of light when the color will be fixed in a certain color.

Fourth, the volume of thin, readers may find it strange, this should be the advantages rather than disadvantages of LCD TV ah! Most of the current LCD TVs are mostly 16 to 9 wide screen modeling, than the traditional four to three visual range of much longer, due to the display screen elongated, but visually smaller than the traditional four to three screen. So used to the traditional 29-inch tube TV people, change the 30-inch wide-screen LCD TV, always feel the display screen is smaller, which is purely visual error, but it is the consumer in the purchase of 30-inch LCD TV has a certain impact, many manufacturers will try to install speakers at both ends of the screen, so that the overall shape seems to be bigger.

Advantages of plasma TV

First, in the 40-inch to 50-inch thin TV, plasma TV's technological development is more mature than LCD TVs and rear-projection TVs, and the current cost per inch is also lower than that of LCD TVs, and the body shape is much thinner than that of rear-projection TVs, which gives plasma TVs a considerable leading edge in the aggregate.

Secondly, plasma TVs do not use magnetic bias or focusing mode to display images, so even if there is a strong magnetic interference, the display image will still be natural and there will be no color bias.

Third, plasma TVs directly emit light from each pixel, so that not only is the picture not distorted in large-size full-flat displays, but the picture quality is quite detailed, and there is no problem with the viewing angle.

Disadvantages of plasma TV

First, the life of the problem, because the plasma TV belongs to the self-luminous, the panel will be because of the attenuation (Burn-in) and make the display color bias, the theoretical half-life of the luminous body (recession to 50%) of the time of 30,000 hours, much lower than the life of 100,000 hours of LCD TVs.

Second, the same as LCD TVs, in the black part of the presentation to be improved. Because plasma TVs use ionic discharge, once the ions are excited by the electrodes, a small portion of the ions will remain to continue the discharge, which will make the darkest pixels are still slightly bright, and present a dark gray instead of black.

Third, due to the luminous principle of the plasma TV, if it is fixed for a long time in the same image or picture, resulting in a continuous discharge of ions against the fixed point, will accelerate the panel exhaustion; viewing four to three picture, the best use of sixteen to nine full-screen playback, so as to avoid prolonged use, resulting in the central attenuation of the screen than the two sides of the more, in short, the plasma TV will be a light-emitting unbalanced problem, so you have to The first is to use a balanced picture to avoid early decay in some areas.

Fourth, the issue of power consumption, plasma TV is quite consuming, the past 42-inch models of power consumption of more than 500 watts, even the latest 43-inch plasma TV, power consumption of nearly 300 watts, no wonder some people joked that the use of plasma TV in the winter, home will not need to turn on the furnace, which is also known as the plasma TV in the power consumption of the disadvantage. This means that there is no need to worry about the quality of the TV set, as it will be difficult to move it around.
