Abstract
A display device, a driving method thereof, and a timing controller thereof able to prevent image defects, such as image insensitiveness, non-uniform luminance, and gradation abnormality, which would otherwise occur when sensing data are not ordinarily acquired from data sequentially transmitted from a plurality of sensing configurations are disclosed.
Claims15
A display device comprising:
- a plurality of sensors each sequentially transmitting data including a transfer start code and sensing data;
- a sensing data acquirer configured to receive the data sequentially transmitted from each of the plurality of sensors in response to a synchronized clock signal and acquire the sensing data from the received data;
- and
- a compensator configured to determine an amount of video data to be compensated based on the sensing data and compensate the video data to be supplied to each of subpixels according to the determined amount to be compensated,
- wherein the synchronized clock signal has a clock edge evading entire transition periods of the data sequentially transmitted from the plurality of sensors.
2 more elements
A method of driving a display device comprising:
- receiving data from each of a plurality of data driver integrated circuits;
- determining whether or not a transfer start code in the data received from each of the plurality of data driver integrated circuits is recognizable;
- responsive to determining that the transfer start code is not recognizable, changing a clock signal until the transfer start code is recognizable;
- responsive to determining that the transfer start code is recognizable, acquiring sensing data from the data received from each of the plurality of data driver integrated circuits;
- determining an amount of video data to be compensated based on the sensing data;
- and
- compensating the video data to be supplied to each of subpixels according to the determined amount to be compensated.

A method of driving a display device comprising:
- receiving data from a plurality of data driver integrated circuits;
- determining whether or not a clock edge of a clock signal evades entire transition periods of the data received from the plurality of data driver integrated circuits;
- responsive to determining that the clock edge of the clock signal is present in the transition period the data received from at least one data driver integrated circuit among the plurality of data driver integrated circuits, changing the clock signal such that a clock edge thereof evades the entire transition periods of the data received from the plurality of data driver integrated circuits;
- responsive to determining that the clock edge of the clock signal evades the entire transition periods of the data received from the plurality of data driver integrated circuits, acquiring sensing data from the data received from the plurality of data driver integrated circuits;
- determining an amount of video data to be compensated based on the sensing data;
- and compensating the video data to be supplied to each of subpixels according to the determined amount to be compensated.
3 more elements
A timing controller comprising:
- a receiver receiving data from a plurality of data driver integrated circuits;
- a sensing data acquirer configured to receive the data received from the plurality of data driver integrated circuits in response to a synchronized clock signal and acquire the sensing data from the received data;
- and
- a compensator configured to determine an amount of video data to be compensated based on the sensing data acquired by the sensing data acquirer and compensate the video data to be supplied to each of subpixels according to the determined amount to be compensated
- wherein the synchronized clock signal has a clock edge evading entire transition periods of the data sequentially transmitted from the plurality of data driver integrated circuits.
