Controller
Control signal for output deselect level
˙The input signal is level-shifted from logic
voltage level to LCD driver voltage level ,
and controls LCD drive circuit
˙When the signal is low,the output (Y1
Y240) of LCD drive be set to level V5,the
contents of shift register are reset not read
˙When this signal return to high, the
operation returns to the normal status.
