3: The way of luminance control with BRTP signal

When PWSEL is “L,” inputting signal pulse from the outside to BRTP enables to control the luminance.

The luminance can be controlled by the duty value of the input signal.

Duty = 100%: luminance is maximum. (100%)

Duty = 20%: luminance is minimum. (30%)

Regarding set up for frequency, refer to the below formula.

Set up frequency = Vsync frequency × (n + 0.25) or (n + 0.75)

But, please fix the frequency after evaluating the display quality sufficiently, because it can be disturbed due to

the frequency.
