3.2.2 Gain/Brightness Control

MTL005 provides Gain and Brightness control to adjust the contrast and brightness of output color by

programming gain and brightness coefficients. This adjustment is applied to RGB colors individually. Auto-

white balance is possible by using this function.

3.2.3 Gamma Correction

Gamma Correction is used to compensate the non-linearity of LCD display panel. MTL005 contains a 8-bit

Gamma table to fix this phenomenon.

3.2.4 Color Dithering

MTL005 supports true color (8 bits per color) or high color (6 bits per color) display.

In the latter case, users can turn on dithering function to avoid artificial contour due to truncation. For

dithering, it supports two methods:

¨ Static dithering: Dithering coefficient is fixed.

¨ Temporal dithering: Dithering coefficient will change by time.
