Key Features
- Selectable number of LCD drive outputs : 324/321/312/309
- Built-in 6-bit digital input DAC
- Dot-inversion drive : Outputs the inverted gray scale voltages between LCD drive pins next to each other
- 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 321output and 309-output modes.
- Possible to display 262 144 colors in 64 gray scales with reference voltage input of 18 gray scales : This reference voltage input corresponds to ‹ correction and intermediate reference voltage input can be abbreviated
