7.11 Display Data Structure and Gradation Control
For the purpose of gradation control, one pixel requires multiple bits of display RAM. The EM65568 has 4-bit data per output
to achieve the gradation display.
The three outputs of the segment driver are used for one pixel of RGB, and the EM65568 is connected to an STN color LCD
panel. It can display 128*130 pixels with 4096 colors (4 bits * 4 bits * 4 bits). In this case, since the gradation display data is
processed by a single access to the memory, the data can be rewritten fast and naturally.
The weighting for each data bit is dependent on the status of the SWAP bit and the REF bit that is selected when data is written
to the display RAM.
* This specification is subject to be changed without notice.
