The LCD panel largely determines the brightness, contrast, color and viewing angle of the LCD. The rapid development of liquid crystal panel is closely related to liquid crystal. Its output, advantages and disadvantages, market environment and other factors are all related to the quality, price and market trend of LCD itself, because about 80% of the cost of an LCD is concentrated on the panel.
The price trend of LCD panel directly affects the price of LCD, and the quality and technology of LCD panel are also related to the overall performance of LCD. In addition, an indispensable technology of the LCD panel is whether the LCD panel can achieve the color of 16.7M of true color display, because from the color point of view, the LCD includes the concept of true color display, that is to say, all three color channels of R.G.B (red, green and blue) have the ability to physically display 256 gray scales.
Not all LCD panel products can physically display true colors. If they have the ability to physically display 167772 16 colors, that is, what we call 16.7M colors at present, then each color channel can display 256 (the eighth power of 2 =256) gray levels, and then it will reach 16.7.
On the other hand, if the color of the LCD panel is 16.2M, the color reproduction ability is relatively weak, and the color of 16.7M can be achieved through hardware dithering, but after all, the color achieved through some technical links is not true, so each channel can only display 64 (the 6th power of 2 =64) gray levels, and it can only be a 6bit panel, which is a pseudo-true color panel.
Compared with the two panels, the 6bit panel can only display 262 144 colors (64×64×64=262 144), and the 8bit panel can display 167772 16 colors (256× 256× 256 =
