Panel type

There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.

OLED
Panel bit depth

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.

10 bits
FRC

Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.

No
Colors

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.

1073741824 colors
30 bits
