LCD(HTPS) has a light-transmitting part (opening part) and a light-blocking part (such as wiring part). ) This technology can focus the light on the opening and let as much light as possible pass through the screen. On the substrate on the light incident side, a lens with a size approximately the same as that of a pixel is completely arranged. After using this technology, the brightness of the screen with a particularly small opening can be improved as high as 1.5 times to 1.6 times.
