Generally, consumers think that when buying a laser TV, you only need to buy a host, and the white wall at home can act as a screen. This perception is wrong. The laser TV must be equipped with a screen.

The white wall has the property of diffuse reflection and can be considered as a curtain with a gain of 1.0. If the light is projected from the front, the reflection effect is acceptable. If the front projection is used, it is not necessary to buy a special screen. However, laser TVs are different. This product uses a reflective ultra-short focal lens, and light is projected from diagonally below the screen. At this time, if the wall is slightly uneven, the picture will appear tortuous.
Since the coating of ordinary screens is designed to cope with the front projection, the reflection angle of the light projected from below is not well grasped, and the brightness of the entire screen will be lost. The anti-light principle of the anti-light curtain adopted by the laser TV is divided into an optical reflection part and an optical absorption part. The anti-light curtain has a complex Fesnier sawtooth mechanism. This structure can cope with the characteristics of laser TV and make the picture brighter.
This kind of anti-light curtain with core technology is more expensive. A 100-inch anti-light curtain costs about 5,000 yuan to buy. At present, the price of laser TVs has dropped rapidly, and there are already 4K laser TVs for 8,999 yuan. For consumers who do not understand this market, it is difficult to accept the phenomenon that the price of a screen is close to that of the host.
The price of laser TV has dropped, but the high-priced anti-light curtain has become a major obstacle to its popularization. Why is there no cheap anti-light curtain? This is because the anti-light curtain market is inherently small, the core technology is in the hands of a few brands, and there are many reasons such as craftsmanship and patents, so there is a lack of competitors in the market. These brands that have mastered the technology cannot judge the scale of the laser TV market, nor dare to invest on a large scale. The current model is to sell at high prices to ensure benefits. Therefore, the market price of anti-light curtains has remained high.
With the increasing sales of laser TVs, the number of brands in the curtain market will increase, and manufacturers with core technologies will continue to observe and adjust their strategies. It is expected that the price of anti-light curtains in the future will still have a lot of room for decline.
Fast Recovery Diode is a semiconductor device which possesses short reverse recovery time for rectification purpose at high frequency. A quick recovery time is crucial for rectification of high-frequency AC signal. Diodes are mostly used in rectifiers because they possess ultra-high switching speed.
