With the development of display technology, stretchable display screens are getting more and more attention. Stretchable display screens are deformable display devices made of flexible materials, and have the advantages of small size, portability, low power consumption, and the like, and thus are increasingly widely used in various fields.

However, current stretchable displays remain to be improved.

Disclosure of Invention

The present invention is based on the discovery and recognition by the inventors of the following facts and problems:

In addition, the second sub-pixels in the first sub-pixel row 1 and the third sub-pixel row 3 are both shifted from the second sub-pixels in the second sub-pixel row 2 by a distance of 1 to 1.5 sub-pixels, as shown in fig. 2, the second sub-pixels 20A in the first sub-pixel row 1 are shifted from the second sub-pixels 20B in the second sub-pixel row 2 by a distance of 1 to 1.5 sub-pixels, and the second sub-pixels 20D in the third sub-pixel row 3 are shifted from the second sub-pixels 20C in the second sub-pixel row 2 by a distance of 1 to 1.5 sub-pixels.

That is, in the present embodiment, the 6 display pixels are formed by using 14 sub-pixels, and thus, the pixel density of the stretched display panel can be significantly increased by using the above pixel arrangement.

According to other embodiments of the present invention, referring to fig. 2, in a group of pixel arrays 210, each of a first subpixel row 1 and a third subpixel row 3 has two first subpixel groups and a second subpixel located between the two first subpixel groups, the second subpixel row 2 has four second subpixels arranged in two columns, and one first subpixel group, the two columns of second subpixels are arranged on both sides of the first subpixel group, wherein the first subpixel group is composed of two first subpixels with different colors. Specifically, as shown in fig. 2, the first sub-pixel row 1 has two first sub-pixel groups of first sub-pixels 10C and 10D, the second sub-pixel 20A is located between the two first sub-pixel groups, the third sub-pixel row 3 has two first sub-pixel groups of first sub-pixels 10E and 10F, the second sub-pixel 20D is located between the two first sub-pixel groups, the second sub-pixel row 2 has a first sub-pixel group of first sub-pixels 10A and 10B, and two columns of second sub-pixels 20B and 20C are arranged on both sides of the first sub-pixel group.

In the present embodiment, the second sub-pixel 20A in the first sub-pixel row 1 and the first sub-pixel group formed by the first sub-pixels 10A and 10B in the second sub-pixel row 2 constitute one display pixel, the second sub-pixel 20D in the third sub-pixel row 3 and the above-mentioned first sub-pixel group in the second sub-pixel row 2 constitute another display pixel, and the first sub-pixels 10A and 10B are shared by the above-mentioned two display pixels.

The first subpixel group formed by the first subpixels 10C and 10D on the right side of the first subpixel row 1 and the second subpixel 20B on the right side of the second subpixel row 2 form a display pixel, and the second subpixel 20C on the right side of the second subpixel row 2 and the first subpixel group formed by the first subpixels 10E and 10F on the right side of the third subpixel row 3 form a display pixel. That is, the present embodiment uses 16 sub-pixels to form 6 display pixels, so that the pixel density of the stretched display panel can be significantly increased by using the above pixel arrangement.

In the present invention, a display pixel in a display portion includes: two display pixels (referred to as first display pixels) configured by the first sub-pixels 10A and 10B and the two second sub-pixels 20A and 20D, respectively, and a display pixel (referred to as second display pixel) configured by the first sub-pixels 10C and 10D and the second sub-pixel 20B. The inventors have found that the arrangement of the plurality of sub-pixels constituting the first display pixels is concentrated, and the pitch between two first display pixels is small, which causes a problem of display unevenness if all the display pixels in the display portion are constituted by the first display pixels. The display pixels comprise the first display pixels and the second display pixels, the problem of uneven display can be relieved, the number of the display pixels in the display part can be increased, and the pixel density of the stretching display panel is improved. According to a preferred embodiment of the present invention, a pixel array (such as the pixel array shown in fig. 2) of 6 display pixels constituted by 16 sub-pixels is provided in the display section. Therefore, under the condition of remarkably improving the pixel density of the stretching display panel, the problem of uneven display can be further alleviated.

The color of the first sub-pixel and the second sub-pixel is not particularly limited, for example, a three primary color scheme of red, green and blue may be adopted, specifically, the first sub-pixel may be a red sub-pixel or a blue sub-pixel, and the second sub-pixel may be a green sub-pixel. Therefore, two first display pixels can be obtained by sharing the red sub-pixel and the blue sub-pixel, so that the pixel density of the stretching display panel is improved.
