324-output TFT-LCD Source Driver IC

Sharp Electronics 

Output Voltage Value

Two voltages are selected from all of the reference

voltages (V0-V63) by the upper 3-bit data (D5, D4

and D3) of the 6-bit input data (D5, D4, D3, D2, D1

and D0) taken by time sharing, and intermediate

value is determined by the lower 3-bit data (D2, D1

and D0).

LH168K

The Vi is a reference voltage (VHi or VLi) that is

determined by the polarity exchange input (REV

and REV2).

Relation between input data and output voltage

values is shown below.

(i = 0, 8, 16, 24, 32, 40, 48, 56, 63)
