5.3 Power On/Off Sequence
The HX8257-A has a power ON/OFF sequence control function. When DISP pin is pulled “H”,
blank data is outputted for 10-frames first, from the falling edge of the following VSYNC signal.
Similarly, when DISP is pulled “L”, 10-frames of blank data will be outputted from the falling
edge of the following VSYNC, too. The blank data would be gray level 0 for normally black LC
(NBW= “H”), and be gray level 255 for normally white LC (NBW= “L”).
