Symbol
This is the Common voltage. The voltage needs to be adjusted.
See "3 BLOCK DIAGRAM - Reference design of COM circuit".
Provide the gamma setting voltages from outside. Maintain the following voltage relationships.
VSS V4 V3 V2 V1 V0 VDD
H: External gamma setting voltage (V0-V4) is valid.
L: External gamma setting voltage (V0-V4) is invalid. (Internal gamma setting is valid.)
This pin inverts the signal input from the POL pin and outputs it following conversion to the VDD
potential at the rising edge of STB.
This pin inverts the input data signal. Input data in synchronization with the shift clock.
INV = L: Normal, INV = H: Data inversion
This pin inverts the output polarity. The polarity inversion signal data is captured at the rising edge of
STB.
The gamma-resistor is switched in accordance with the positive/negative polarity.
POL = H: Positive polarity
POL = L: Negative polarity
