‹ (gamma) Correction Value

Between reference voltage input pins, 7 or 8

resistors of the same resistance value are

connected in series.

When the resistance ratio between respective

LH168A

reference voltage input pins matches the reference

voltages (V2 to V9) for ‹ correction of LCD panel,

the external power supply of the intermediate

voltages (for V2 to V9 pins) is not required.
