What's the difference between a laser projector and an ordinary projector? Why do so many people recommend laser projectors?
1. First of all, the biggest difference between them is the light source. Laser projection uses solid-state laser as light source, while traditional projectors and most of them use ultra-high pressure mercury lamps. Their life span is also different. The service life of laser light source can reach more than 20,000 hours, and it can be used for 8.5 years based on 8 hours per day. The life of a projector is 5000 hours, and it is usually used for about 2 years. This also leads to the high cost of the laser light source itself and the large one-time investment cost, but the subsequent replacement cost is small, while the light bulb is just the opposite;
2. Ordinary projection adopts the principle of LCD projection, and the image is still displayed on the existing panel, but the picture is projected onto the curtain through a stronger light source and lens; Laser projection adopts DLP projection, and its principle is to use many small mirrors, each of which controls the angle of light to achieve different intensity control, and the emitted light hits the curtain through the lens to form an image;
3. The limitation of projection distance and principle leads to higher requirements for space for general projectors, which requires greater indoor environment and projection distance; The laser uses reflective short-focus projection, so it can project a large picture of 100 inch or more at a distance of half a meter;
4. Traditional projectors have a long projection distance and need a good curtain, but most of them adopt the principle of diffuse reflection to avoid direct reflection of strong light, so the light resistance is weak. The laser projection based on the reflective off-line projection principle can shorten the projection distance, with higher brightness and stronger light resistance.
As far as this product is concerned, the hardware configuration of Betan Laser Projection X3 is the highest in the same price range, and the brightness of the laser light source he uses is as high as 3200ANSI lumens, which is similar to the current light bulb machine. It is no problem to open the curtains during the day.
Betancon X3 projector has MediaTek MT9669 quad-core chip, 3GB memory and 64GB Emmc 5. 1 flash memory. The processor supports global MEMC motion compensation technology, HDR 10+ decoding, and has AI intelligent image quality enhancement function.
In terms of software, the projector is equipped with Betancon OS system, which can connect 5GHz WiFi to request movies, TV series and other resources, and also supports remote retrieval function. The projector supports active shutter 3D technology and can watch 3D movies.
In terms of audio, Betancon X3 has two built-in 10W speakers, supports the viper sound effect, and has Dolby and DTS certification. In addition, the projector has a built-in heat pipe to ensure heat dissipation in a small volume.
So, no wonder so many people recommend it!
