FEATURES
鈥?Number of LCD drive outputs : 384
鈥?Built-in 8-bit digital input DAC
鈥?Dot-inversion drive : Outputs the inverted gray
scale voltages between LCD drive pins next to
each other
鈥?2-port input for each circuit of data inputs R, G
and B, and it is possible to sample and hold
display data of two pixels at the same time
鈥?Possible to display 16.7 million colors in 256 gray
scales with reference voltage input of 18 gray
scales : This reference voltage input corresponds
to 鈥?correction and intermediate reference voltage
input can be abbreviated
鈥?Cascade connection
鈥?Sampling sequence :
Output shift direction can be selected
