DESCRIPTION

The LH168K is a 324-output TFT-LCD source driver IC which can simultaneously display 262 144 colors in 64 gray scales.

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 321-output 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

• Cascade connection

• Sampling sequence : Output shift direction can be selected XO1, YO1, ZO1/XO108, YO108, ZO108 or ZO108, YO108, XO108/ZO1, YO1, XO1

• Shift clock frequency : 55 MHz (MAX.)

• Supply voltages

— VCC (for logic system) : +2.7 to +3.6 V

— VLS (for LCD drive system) : +12 V (MAX.)

• Package : 395-pin TCP (Tape Carrier Package)
