Abstract

Claims (23)

1. A method of making a display device, comprising:

forming a plurality of light-emitting elements on a substrate defining a plurality of sub-pixels; each of the plurality of sub-pixels comprising one of the plurality of light-emitting elements; the plurality of light-emitting elements being arranged to be a light-emitting element array, the display device defining a plurality of pixels, each of the plurality of pixels comprising 2*2 sub-pixels in two adjacent rows and two adjacent columns, the light-emitting elements in each of the plurality of pixels configured to emit light of same color;

detecting whether each of the plurality of light-emitting elements is defective and recording positions of the light-emitting elements that are defective in the light-emitting element array;

setting a resolution of the display device to be a maximum resolution when it is detected that there is no defective light-emitting element in the light-emitting element array;

setting a resolution of the display device to be an adjustment resolution when it is detected that there are defective light-emitting elements in the light-emitting element array, and the adjustment resolution being less than the maximum resolution; and

when no defective light-emitting element is detected, and when all of the plurality of pixels and all of the plurality of sub-pixels are set to be full-color array, setting each of the plurality of light-emitting elements participates in displaying image, and configuring the 2*2 sub-pixels in two adjacent rows and two adjacent columns to be a pixel unit of the display device for light-emitting display.

2. The method of claim 1 , wherein the pixel unit consists of two sub-pixels emitting green light, one sub-pixel emitting blue light, and one sub-pixel emitting red light.

3. The method of claim 1 , wherein the pixel unit consists of two sub-pixels emitting red light, one sub-pixel emitting green light, and one sub-pixel emitting blue light.

4. The method of claim 1 , wherein the pixel unit consists of two sub-pixels emitting blue light, one sub-pixel emitting green light, and one sub-pixel emitting red light.

5. The method of claim 1 , wherein the pixel unit consists of four sub-pixels emitting light of four different colors.

6. The method of claim 1 , wherein when it is detected that there are defective light-emitting elements in the light-emitting element array, the step of setting the resolution of the display device to be the adjustment resolution comprises: counting a number of defective light-emitting elements in each of the plurality of pixels, recording a maximum number of defective light-emitting elements in the plurality of pixels as M, and the adjustment resolution is ¼ of the maximum resolution, and the M is greater than 0 and less than 4.

7. The method of claim 6 , wherein each of the plurality of pixels performs light-emitting display by N undefective light-emitting elements among the four light-emitting elements constituting the pixel, wherein N=4−M.

8. The method of claim 1 , wherein when it is detected that there are defective light-emitting elements and both all of the plurality of pixels and all of the plurality of sub-pixels are set to be full-color array, 2*2 pixels in two adjacent rows and two adjacent columns are configured to be a pixel unit of the display device for light-emitting display.

9. The method of claim 8 , wherein the pixel unit consists of two pixels emitting green light, one pixel emitting blue light, and one pixel emitting red light;

or the pixel unit consists of two pixels emitting red light, one pixel emitting green light, and one pixel emitting blue light;

or the pixel unit consists of two pixels emitting blue light, one pixel emitting green light, and one pixel emitting red light;

or the pixel unit consists of four pixels emitting light of four different colors.

10. The method of claim 8 , wherein the plurality of sub-pixels and the plurality of pixels form Bayer array format; the plurality of sub-pixels form a plurality of first units, a plurality of second units, and a plurality of third units;

each of the plurality of first units consists of 2*2 sub-pixels comprising two green sub-pixels emitting green light along a first diagonal, one red sub-pixel emitting red light, and one blue sub-pixel emitting blue light;

each of the plurality of second units consists of 2*2 sub-pixels comprising two green sub-pixels emitting green light along a second diagonal, one red sub-pixel emitting red light, and one blue sub-pixel emitting blue light;

the first diagonal and the second diagonal are perpendicular to each other, and the first unit and the second unit are alternately distributed in both X and Y directions;

each of the plurality of third units consists of 2*2 pixels comprising two green pixels emitting green light along a third diagonal, one red pixel emitting red light, and one blue pixel emitting blue light;

the third units are repeatedly distributed in the X and Y directions, the third diagonal is parallel to the first diagonal.
