Description
Input/output for chip select or data of the shift register.
AC signal input for LCD driving waveform
-The input signal is level-shifted from logic voltage level to the LCD
driver voltage level, and it controls the LCD driver circuit
-Normally, inputs a frame inversion signal.
The LCD driver output pin’s output voltage level can be set using the
shift register output signal and the FR signal.
Latch pulse input/shift clock input for the shift register.
Display data shift clock input for segment mode.
Control input for deselect output level.
Input pin for display data.
Power supply for logic.
Ground (0V)
Positive power supply for LCD driving voltage. *
Ground (0V)
No connection
Anode of backlight
Cathode of backlight.
* This pin should be NC (No Connection) when Built-in DC/DC converter is used
