3.2.2 Gain/Brightness Control

MTL004 provides Gain and Brightness control to adjust the contrast and brightness of output color by

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

Auto-white balance can be achieved by using this function.

3.2.3 Gamma Correction

Gamma Correction is used to compensate the non-linearity of LCD display panel. MTL004 contains an 8-bit

Gamma table to fix this phenomenon.

3.2.4 Color Dithering

MTL004 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. The

dithering function works in two modes:

¨ Static dithering: Dithering coefficient is fixed.

¨ Temporal dithering: Dithering coefficient is time dependent.

3.3 Output Processor

General Description

Output processor provides the interface for both LCD panel and OSD controller. The output frame rate must

be equal to the input frame rate and output display time must be equal to input display time since there is no

frame buffer present.
