Overlay block mix mode is following 4 ways listed below:
Transparent (Display)

Background Transparent (0 bits = Display)
Translucent ((D OSD)/2)
RGB Offset and Gamma controller Block:
The RGB offset function is used to adjust brightness of RGB data. It provides a simple shift
(positive or negative) for each of the 3 color channels.
The Gamma Correction Block controls the linearity of RGB data.
It is used to adjust the RGB data according to the individual display characteristics and human
eyes favorite. In addition, the gamma table may be used for contrast, brightness, and white
balance (temperature) adjustment. The Gamma Correction linearity can be programmed
through host interface.
Dithering Block
The Dithering Block generates output RGB data for TFT panels that have fewer than 8 bits for
R, G and B input. Mascot V uses a proprietary algorythm to generate smooth shade colors.
Panel Interface
Mascot V chip interfaces with all commonly used active matrix flat panel, e.g. 640x480,
800x600, and 1024x768 .
