Abstract
A display apparatus and a control method thereof are provided. The method includes receiving image data, processing the image data, and dividing a display panel into a plurality of regions, synchronizing a scanning timing of the image data at which the processed image data is scanned in a first region among the plurality of regions with a backlight-on timing of the display panel, and outputting the processed image data in the display panel. The outputting the processed image data includes compensating and outputting the processed image data according to a relation between a scanning timing of the image data for each region of the plurality of regions of the display panel and the synchronized backlight-on timing.
Claims20
A control method to control a display apparatus, the method comprising:
- receiving image data;
- processing the image data;
- and
- dividing a display panel into a plurality of regions, synchronizing a scanning timing of the image data at which the processed image data is scanned in a first region among the plurality of regions with a backlight-on timing of the display panel, and outputting the processed image data in the display panel,
- wherein the outputting the processed image data comprises:
- compensating and outputting the processed image data according to a relation between a scanning timing of the image data for each region of the plurality of regions of the display panel and the synchronized backlight-on timing;
- compensating image data included in the first region, to which a first scanning timing is applied, from among the plurality of regions based on a first Dynamic Capacitance Compensation (DCC) gain value;
- and
- compensating image data included in a second region, to which a second scanning timing is applied, from among the plurality of regions based on a second DCC gain value larger than the first DCC gain value, the second scanning timing being slower than the first scanning timing, and
- wherein the first region and the second region have the same backlight-on timing.
A display apparatus comprising:
- a display panel;
- a plurality of backlights configured to supply light to the display panel;
- a backlight driver configured to control the plurality of backlights;
- and
- a processor configured to:
- control the backlight driver to process image data received in the display panel, divide the display panel into a plurality of regions;
- synchronize a scanning timing of the image data at which the processed image data is scanned in a first region among the plurality of regions with a backlight-on timing of the display panel;
- compensate and output the processed image data according to a relation between a scanning timing of the image data for each region of the plurality of regions of the display panel and the synchronized backlight-on timing;
- compensate image data included in the first region, to which a first scanning timing is applied, from among the plurality of regions based on a first Dynamic Capacitance Compensation (DCC) gain value;
- and
- compensate image data included in a second region, to which a second scanning timing is applied, from among the plurality of regions based on a second DCC gain value larger than the first DCC gain value, the second scanning timing being slower than the first scanning timing,
- wherein the first region and the second region have the same backlight-on timing.
