Block Functions
LCD Drive Circuit
The 240-bit LCD drive circuit generates three voltage levels VH, VL, and VM, which drive the LCD panel.
One of these three levels is output to the corresponding Y pin, depending on the data in latch circuit (2), the
correction signals (CC1 to CC4), and the
DISP
signal.
Correction Circuit
This circuit corrects the shadowing volume.
(2.1) The circuit compares the crosstalk correction signals (CC1 and CC2) from the external circuits and
present output, and determines whether the effective value is increased due to crosstalk. If the effective
value is increased, the output level is reset to the VM level.
