Display Color
The HD66841 converts the RGB color data normally used for CRT display into monochrome, 8-level gray
scale, or 8-color display data.
Monochrome Display (Mode 1 to 5):
The HD66841 displays two colors: black (display on) and white
(display off). As shown in Table 10, the CRT display RGB data is ORed to determine display on/off.
8-Level Gray Scale Display (Mode 6 to 8):
The HD66841 thins out data on certain lines or dots to provide
an 8-level gray-scale display based on CRT display color (luminosity). The relationship between CRT
display color (luminosity) and LCD gray scale (contrast) is shown in Table 11.
This relationship corresponds to the default values in palette registers; the correspondence between color
and gray scale can be changed by writing data into palette registers.
