Patent ID: 11893945
Assignee: LG DISPLAY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. The display device of claim 1, wherein each of the gamma compensation voltage generator includes:
a first circuitry that divides the reference voltage using a voltage divider circuit and selects, from the divided reference voltages, gamma reference voltages including an uppermost gamma reference voltage and a lowest gamma reference voltage;
a second circuitry that divides the gamma reference voltages and selects the remaining gamma reference voltages from the divided reference voltages; and
a third circuitry that divides the gamma reference voltages output from the first circuitry and the second circuitry and outputs gray scale-specific gamma compensation voltages,
wherein the first circuitry, the second circuitry, and the third circuitry are integrated in a drive integrated circuit (IC) or the third circuitry is integrated in the drive IC.
