FEATURES
鈥?Selectable number of LCD drive outputs :
324/321/312/309
鈥?Built-in 6-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 at
324-output and 312-output modes. 1-port input for
each circuit of data inputs R, G and B at 321-
output and 309-output modes.
鈥?Possible to display 262 144 colors in 64 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
