Abstract
Provided are a data processing device, a display device, and deterioration compensation method of the data processing device to determine a burn-in occurrence region by recognizing a user's touch in a display device including a touch function and accurately perform a degradation compensation on the burn-in occurrence region.
Claims14
A data processing device comprising:
- a reception circuit configured to recognize user's rubbing on a screen, to specify a rub region in which the screen rubbing occurs in a touch display panel in which a plurality of pixels are arranged, and to subsequently receive sensing region data for a pixel sensing region including the rub region from an external device specifying the pixel sensing region;
- and
- a degradation compensation circuit configured to classify pixels arranged in the pixel sensing region as a sensing target using the sensing region data, to receive pixel sensing data for the sensing target from a pixel sensing device, to determine whether a burn-in occurs in the pixel sensing region using the pixel sensing data, and to perform a degradation compensation on the sensing target when it is determined that a burn-in occurs in the pixel sensing region.
A display device comprising:
- a touch driving device configured to recognize a user's touch on a touch display panel through a plurality of touch sensors arranged in the touch display panel, to generate touch data including touch coordinate information for the touch, and to transmit the generated touch data to an external device;
- a pixel sensing device configured to sense characteristic values of a plurality of pixels arranged in the touch display panel;
- and
- a data processing device configured to, when the external device determines that a rub region for a user's screen rubbing occurs on the touch display panel using the touch data, receive sensing region data for a pixel sensing region including the rub region from the external device, to classify pixels arranged in the pixel sensing region as a sensing target using the sensing region data, to receive pixel sensing data including only characteristic values of the sensing target from the pixel sensing device, and to subsequently determine whether a burn-in occurs in the pixel sensing region using the pixel sensing data.

A degradation compensation method of a data processing device, the degradation compensation method comprising:
- a region information receiving operation in which, when an external device receiving touch data from a touch driving device determines that a rub region for a user's screen rubbing occurs in a touch display panel using the touch data, sensing region data for a pixel sensing region including the rub region is received from the external device;
- a sensing region classifying operation in which pixels of the pixel sensing region are classified as a sensing target using the sensing region data;
- a partial sensing data receiving operation in which partial sensing data, including only characteristic values of the sensing target, is received from a pixel sensing device sensing characteristic values of a plurality of pixels arranged in the touch display panel;
- a degradation determining operation in which sensing data for comparison to be compared with the partial sensing data is selected among previously stored general sensing data including the characteristic values of the plurality of pixels and whether a burn-in occurs in the pixel sensing region is determined using the partial sensing data and the sensing data for comparison;
- and
- a degradation compensation operation in which a degradation compensation is performed on the sensing target when it is determined that a burn-in occurs in the pixel sensing region.
