The gray scale effect is generated by controlling the pulse width (PW) of current drive phase, except GS0
there is no pre-charge (phase 2, 3) and current drive (phase 4). The driving period is controlled by the gray
scale settings (setting 0 ~ setting 180). The larger the setting, the brighter the pixel will be. The Gray Scale
Table stores the corresponding gray scale setting of the 16 gray scale levels (GS0~GS15) through the
software commands B8h or B9h.
As shown in
Note that the frame frequency is affected by GS15 setting.
