8.5.2.2

Frame inversion mode (driving scheme B)

In frame inversion mode, the DC value is compensated across two frames and not within

one frame. Changing the inversion mode to frame inversion reduces the power

consumption, therefore it is useful when power consumption is a key point in the

application.

Frame inversion may not be suitable for all applications. The RMS voltage across a

segment is better defined, however since the switching frequency is reduced there is

possibility for flicker to occur.

8.5.3 Command: Display-ctrl

The Display-ctrl command enables or disables the display.
