Patent ID: 11908422
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A data driving circuit, comprising:
a digital-analog converter to receive image data of a digital format, to receive a reference voltage to generate a plurality of gamma reference voltages based on the reference voltage, and to convert the image data of the digital format into analog data signals of an analog format based on a portion of the plurality of gamma reference voltages,
wherein the digital-analog converter comprises:
a plurality of gamma decoders to generate a plurality of global gamma reference voltages, each of the plurality of global gamma reference voltages being generated based on at least some of the plurality of gamma reference voltages; and
a decoder to output one of the plurality of global gamma reference voltages corresponding to the image data of the digital format to generate the analog data signals, and
wherein at least some of the plurality of gamma decoders are turned off while remaining gamma decoders among the plurality of gamma decoders except for the at least some of the plurality of gamma decoders maintain a turn-on state,
wherein the at least some of the plurality of gamma decoders are turned off based on the image data of the digital format.
