- W2947858825 abstract "Display technology is the main source for humans to obtain information and entertainment. Increased display screen size is a trend, whether on mobile phone or television, and projection display has become increasingly popular in achieving large screen displays. Previous projection display systems have used a traditional light bulb which cannot be modulated, so the power of the display device is constant and the contrast of the display device can only be improved by controlling the size of the aperture in the light path. With the appearance of solid-state light sources, i.e., lasers, the luminance of the light source can be modulated according to the image content so that the power of the light source can be reduced and the dynamic contrast can be improved simultaneously. A method to modulate the power of the laser light source on a frame-to-frame basis in response to the input image data is shown. An ultrahigh contrast is achieved with the laser display. A dynamic contrast of greater than 100,000:1 can be achieved, and the average power consumption of the laser TV can be reduced by about 20% with typical video source material." @default.
