Set dark area dynamic Y γ gain [1C] to MIN [03], and dark area static Y γ gain [1C] to 0dB [17].
Set PS1 to V
Set PS1 VDGP [V], and measure #43 picture period voltage VDDGMIN [V].
Set dark area dynamic Y γ gain [1C] to MAX [D7], PS2 to 1.2 V, measure voltage VDDGMAX [V] of #43
picture period when PS1 is VDGP [V], and calculate the following equations.
