The "Bayer format" mentioned in this article refers to an arrangement format of sub-pixels in a digital image invented by Bryce Bayer, a scientist at Eastman Kodak Company, also known as a Bayer array. The human eye is more sensitive to green, so in the Bayer format, the sub-pixels whose emission color is green (G) are the sub-pixels whose emission color is red (R) and the sub-pixels whose emission color is blue (B). The sum, and in the Bayer array, consists of green sub-pixels accounting for 1/2 in number, red sub-pixels accounting for 1/4 in number, and blue sub-pixels accounting for 1/4 in number. In the Bayer array, the four sub-pixels in two adjacent rows and two adjacent columns are two green sub-pixels, one red sub-pixel and one blue sub-pixel. The pixels form a matrix with multiple rows and multiple columns to form the Bayer array.

The "resolution" mentioned herein refers to the number of pixels that a display device can display. When the size of the display screen of the display device is fixed, the higher the display resolution, the clearer the image.

In this embodiment, all the light emitting elements 10 emit the same color light in the three primary colors of red, green and blue (RGB), that is, the display device 100 may be a single-color display device.

Refer to Figure 3. In this embodiment, the light-emitting elements 10 of the light-emitting element array 11 may emit light of different colors, that is, the display device 100 may be a multi-color display device (full-color array display device).

In one embodiment, each light-emitting element 10 emits light of one of the three primary colors of red, green and blue (RGB), and all large sub-pixels 13 and all sub-pixels 12 are set in the Bayer array format. The Bayer array format is a type of full-color array. Specifically, in the Bayer array format formed by all the sub-pixels 12, the green-emitting sub-pixels 12G, A sub-pixel 12R emitting red light and a sub-pixel 12B emitting blue light form a first small cell C1, which is distributed by two adjacent two rows and two adjacent columns in a second diagonal line I2. A sub-pixel 12G emitting green light, a sub-pixel 12R emitting red light, and a sub-pixel 12B emitting blue light form a second small unit C2, and the first diagonal line I1 and the second pair The corner lines I2 are perpendicular to each other, and the first small cell C1 and the second small cell C2 are alternately distributed in the X direction and the Y direction to form the Bayer array format composed of all sub-pixels 12; In the Bayer array format formed by the sub-pixels 13, two large sub-pixels 13G emitting green light and one emitting The large sub-pixel 13R and a large sub-pixel 13B emitting blue light form a large cell C3, which is repeatedly distributed in the X and Y directions to form the Bayer composed of all the large sub-pixels 13 Array format.

When the light-emitting element 10 does not emit light, it is determined as a damaged light-emitting element; or when the light-emitting element 10 emits a brightness lower than a predetermined brightness, it is determined as a damaged light-emitting element.

In step S3, when and it is detected that there is no damaged light-emitting element 10 in the light-emitting element array 11 and all the light-emitting elements 10 of the large sub-pixels 13 have the same light-emitting color (that is, the display device 100 is a monochrome display time), each light-emitting element 10 of the light-emitting element array 11 is set to participate in displaying an image, and a sub-pixel 12 is a pixel unit 14 when the light-emitting element array 11 performs light-emitting display, as shown in FIG. 4 . Show. That is, the resolution of the display device 100 is configured to be the maximum resolution. One pixel unit 14 is one image pixel point when the image is displayed, that is, the smallest display unit when the image is displayed.

In step S3, when all large sub-pixels 13 and all sub-pixels 12 are set to a full-color array and it is detected that there is no damaged light-emitting element 10 in the light-emitting element array 11, they will be distributed in adjacent The four sub-pixels 12 in two rows and two columns are one pixel unit 14 when the display device 100 performs light-emitting display.

The method for manufacturing a display device according to claim 5, wherein when all large sub-pixels and all sub-pixels are set in a full-color array and it is detected that there are damaged light-emitting elements in the light-emitting element array, The four large sub-pixels distributed in two adjacent rows and two columns are one pixel unit when the display device performs light-emitting display. The method for manufacturing a display device according to claim 5, wherein the pixel unit is composed of two large sub-pixels emitting green light, one large sub-pixel emitting blue light, and one large sub-pixel emitting red light formed by two sub-pixels emitting red light, one sub-pixel emitting green light, and one sub-pixel emitting blue light; or two sub-pixels emitting blue light and one sub-pixel emitting green light A pixel is formed with one sub-pixel emitting red light; or with four large sub-pixels that all emit different colors. The method for manufacturing a display device according to claim 3 or 8, wherein two sub-pixels emitting green light and one emitting sub-pixel located in two adjacent rows and two adjacent columns are distributed in a first diagonal line. The red sub-pixel and one blue-emitting sub-pixel form a first small unit, which consists of two second diagonally distributed green-emitting sub-pixels located in two adjacent rows and two adjacent columns. A pixel, a sub-pixel emitting red light, and a sub-pixel emitting blue light form a second small unit, the first diagonal line intersects the second diagonal line, and the first small unit and the first small unit Two small cell loops are alternately distributed in the X direction and the Y direction; two large sub-pixels that emit green light and one emission A large sub-pixel for red light and a large sub-pixel for emitting blue light form a large unit, and the third diagonal line is parallel to the first diagonal line; the large unit is repeatedly distributed in the X direction with the Y direction; thus all sub-pixels form a Bayer array format simultaneously with all large sub-pixels.
