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
',63
signal and
the combination of the M signal and the data in latch circuit (2).
Level Shifter
The level shifter changes logic control signals into LCD drive signals.
Latch Circuit (2)
240-bit latch circuit (2) latches data input from latch circuit (1), and outputs the latched data to the level
shifter, both at the falling edge of each clock 1 (CL1) pulse.
