scanning control circuit
1-, 2-, 16-, 32-line scanning control circuit
Selects the number of simultaneously scanned lines, and controls the shift register. Consists of a
decoder and a counter.
Gate drive waveform switching circuit
Generates control signals enabling support of different drive systems: dot inversion, counter-electrode
inversion, and drive using coupling capacitances.
Bidirectional shift register
Shifts the scanning signal bidirectionally in accordance with the shift-direction switching signal SHL.
Level shifter
Steps up the V
CC
and GND level signal amplitudes to the V
LCD
and V
EE
levels.
Gate-line drive circuit
Selects and outputs one of three levels—gate-on voltage VH, gate-off voltage VL, or VM—according
to the stepped-up scanning signal and alternation signal M.
