Abstract

Claims (29)

1 . A display device, comprising:

a display panel comprising pixels;

a cover element; and

a decorative element arranged on the cover element, wherein an individual brightness of the pixels of the display panel is adapted to a light transmissivity of the decorative element at the respective pixel positions, based on a correction map which comprises a determined light transmissivity of the decorative element at positions of the pixels, or a value derived therefrom.

2 . The display device according to claim 1 , wherein the adaptation of the individual brightness of the pixels is adjusted to a viewer position.

3 . The display device according to claim 1 , wherein the correction map is derived from a known pattern of the decorative element.

4 . The display device according to claim 1 , wherein the correction map is obtained in an end-of-line calibration process after production of the display device.

5 . The display device according to claim 1 , wherein the correction map is updatable during operation of the display device.

6 . The display device according to claim 1 , wherein the individual brightness of the pixels is adapted to the light transmissivity of the decorative element individually for different emission wavelengths of the pixels.

7 . The display device according to claim 1 , wherein the individual brightness of the pixels is adapted by controlling a pixel luminance when addressing the pixels with a drive signal.

8 . The display device according to claim 1 , wherein the display device is a 3D display device.

9 . The display device according to claim 1 , further comprising an integrated gesture sensing module or an integrated camera.

10 . A method for providing a correction map for a display device, comprising:

displaying a test image with the display device;

determining a light transmissivity of a decorative element of the display device at positions of pixels of a display panel of the display device;

storing the determined light transmissivity or a value derived therefrom in the correction map, and

adapting an individual brightness of the pixels on the correction map.

11 . The method according to claim 10 , wherein the method is performed in an end-of-line calibration process after production of the display device or in a calibration process during operation of the display device.

12 . A method for operating a display device, comprising:

displaying a test image with the display device;

determining a light transmissivity of a decorative element of the display at positions of pixels of a display panel of the display device

retrieving a correction map; and

adapting an individual brightness of pixels of a display panel of the display device by controlling a pixel luminance based on the correction map when addressing the pixels with a drive signal.

13 . A computer program code comprising instructions stored on a nontransient computer readable medium, which, when executed by at least one processor, cause the at least one processor to perform a method for operating a display device, comprising:

displaying a test image with the display device;

determining a light transmissivity of a decorative element of the display device at positions of pixels of a display panel of the display device; and

storing the determined light transmissivity or a value derived therefrom in the correction map;

retrieving a correction map; and

adapting an individual brightness of pixels of a display panel of the display device by controlling a pixel luminance based on the correction map.
