1. RGB three primary colors: The time division method does not require CF to segment the three RGB colors, but is operated by the three RGB backlights separately. Not using CF can reduce the cost of LCD, without the absorption of CF color layer can greatly improve the efficiency of light utilization, without the need to divide into three sub pixels, it can improve the pixel aperture ratio or improve the resolution of TFT-LCD. The backlight of RGB three primary colors each plays a role, which is beneficial for improving the display quality of TFT-LCD.
2. RGB brightness control: Control the brightness of the RGB primary colors sequentially through the liquid crystal effect in the corresponding area of the pixel. Compared with the pixel segmentation method, controlling three sub pixels in space has changed to controlling one complete pixel, but in time it has changed from 1/60 second (I6 To achieve LCD control within 7ms, it takes 1/180 second (5 Realize LCD control within 6ms.
To achieve color display using time division method and achieve excellent display quality. The response speed of LCD should reach 1/3 of the frame rate (2-3ms) at the slowest. Fast LCD response also requires fast circuit driving capability. Therefore, these requirements for liquid crystal materials and liquid crystal display modes are a major bottleneck in the application of time division method.
3. RGB color fusion: Time segmentation method utilizes the temporal fusion of colors. The ideal imaging condition is to project one frame of blue, one frame of green, and one frame of red onto the same position on the retina, in order to ensure that the three frames can be visually reproduced completely.
If these three frames are projected at different positions on the retina, the observer will form a separation and misalignment of the three frames during visual reproduction, known as the color separation effect. The phenomenon of color separation not only reduces visual quality, but also causes dizziness when viewed for a long time. So, the potential color separation effect is another major bottleneck in the application of time division methods.
