Abstract

A display device adapted to minimize brightness deterioration and motion blurring in a motion picture and a driving method thereof are disclosed. The display device may include a data aligning part that analyzes a gray level of input data and inserts black data into frame data having less than a designated reference gray level; and a driver that displays the data from the data aligning part in a display panel.

Claims

1. A display device, comprising:

a data aligning part that analyzes a gray level of input data and inserts black data into data having less than a designated reference gray level to align data; and

a driver that displays the data from the data aligning part in a display panel.

2. The display device according to claim 1, wherein the data aligning part does not insert the black data into data having at least the designated reference gray level.

3. The display device according to claim 1, wherein the driver includes:

a data driver that converts the data aligned by the data aligning part into an analog data voltage and supplies the analog data voltage to data lines of the display panel; and

a scan driver that sequentially supplies a scan pulse to scan lines that cross the data lines.

4. The display device according to claim 3, wherein the driver further includes a timing controller that supplies the input data to the data aligning part, supplies the data aligned by the data aligning part to the data driver, and controls the data driver and the scan driver.

5. The display device according to claim 4, wherein the data aligning part is embedded within the timing controller.

6. The display device according to claim 4, wherein the timing controller includes a signal controller.

7. The display device according to claim 6, wherein the signal controller generates a vertical/horizontal synchronization signal, a clock signal and a data enable signal.

8. The display device according to claim 4, wherein the timing controller samples digital video data in accordance with a pixel clock.

9. The display device according to claim 1, wherein the data aligning part inserts the black data for one frame period.

10. The display device according to claim 1, wherein the device is a liquid crystal display device or an organic light emitting diode device.

19. The displaying method according to claim 1, further comprising:

inserting the black data for one frame period.

11. A displaying method, comprising:

aligning data by analyzing a gray level of input data and inserting black data into data having less than a designated reference gray level; and

displaying the aligned data in a display panel.

12. The displaying method according claim 11, further comprising:

not inserting the black data into data having at least the designated reference gray level.

13. The displaying method according to claim 11, further comprising:

converting the aligned data into an analog data voltage and supplying the analog data voltage to data lines of the display panel; and

sequentially supplying a scan pulse to scan lines that cross the data lines.

14. The displaying method according to claim 13, further comprising:

providing a timing controller that supplies the input data to a data aligning part, supplies the data aligned by the data aligning part to a data driver, and controls the data driver and a scan driver.

15. The displaying method according to claim 14, wherein the data aligning part is embedded within the timing controller.

16. The displaying method according to claim 14, wherein the timing controller includes a signal controller.

17. The displaying method according to claim 16, further comprising:

generating a vertical/horizontal synchronization signal, a clock signal and a data enable signal.

18. The displaying method according to claim 14, further comprising:

sampling digital video data in accordance with a pixel clock.

20. The displaying method according to claim 11, wherein the display panel is a liquid crystal display panel or an organic light emitting diode panel.
