Table 4.3 Transparent dot data values
Color Format | Character Colors | bits per dot | transparency code |
Palette format | 16 colors | 4 bits / Dot | 0H (4 bits) |
256 colors | 8 bits / dot | 00H (8 Bit) | |
2048 colors | 16 bits / dot | 000H (lower 11 bits) | |
RGB format | 32768 colors | 16 bits / Dot | MSB (bit 15) is 0 |
16.77 million colors | 32 bits / dot | MSB ( (Bit 31) is 0 |
RGB dot data
- When the color format is RGB, the number of character colors can be selected from 32768 colors and 16.77 million colors. In the case of 16.77 million colors, RGB is specified by 8 bits, but in the case of 32768 colors, the upper 5 bits of 8 bits of RGB are specified, and the lower 3 bits are fixed to 0. The most significant bit is a transparent bit that specifies whether or not it is a transparent dot. When it is 0, it becomes a transparent dot.
∙ If the transparent code is specified to be disabled in the screen display enable register, the transparent bit is ignored.
The dot data in RGB format is shown in Figure 4.6.
