Note) In case of lower frequency, the deterioration of display quality, flicker etc., may be

occurred.

7-2) Horizontal display position

①In case ENAB is active

The horizontal display position is determined by ENAB signal and the input data

corresponding to the rising edge of ENAB signal is displayed at the left end of the active area.
