Description

Display panel and display device

Technical Field

The present invention relates to the field of display technologies, and in particular, to a display panel and a display device.

Background

Currently, display technology has penetrated various aspects of people's daily life, and accordingly, more and more materials and technologies are used for display screens. The display panel is used as an important component of the display device to realize the display function of the display device. Nowadays, the mainstream display screen mainly includes a liquid crystal display panel and an Organic Light-Emitting display panel (OLED).

The liquid crystal display panel has the advantages of lightness, thinness, low power consumption, low radiation and the like, and is widely applied to various fields. Organic Light Emitting Diodes (OLEDs) are increasingly used in high performance display as a current-mode light emitting device, and OLED display panels have many excellent characteristics such as self-luminescence, wide viewing angle, fast response speed, high contrast, wide color gamut, low energy consumption, thin panels, rich colors, flexible display, and wide operating temperature range, and are thus known as "star" flat panel display technologies of the next generation.

sub-Pixels of the liquid crystal display panel are usually arranged in an RGB standard array, and the distance between adjacent sub-Pixels is small, so that the design of high image resolution (Pixels Per Inc, PPI) can be realized, and the design is relatively perfect; for the organic light emitting display panel, because the service life of each color sub-pixel of the organic light emitting display panel is different, each color sub-pixel needs to be designed to be different in size, and in addition, the size of the opening of the high-precision metal mask directly determines the size of the sub-pixel, so that the high-precision metal mask has a limitation on the preparation process, each color sub-pixel is designed to be a circular structure and the like which are symmetrical, and each color sub-pixel is designed to be a special pixel arrangement by a common algorithm for uniform color mixing, so that the standard RGB matrix arrangement is difficult to be made, but special pixel arrangement structures such as delta arrangement and 2in 1 arrangement are adopted, but the special pixel arrangement structures inevitably cause a small opening ratio, namely a pixel definition layer is not fully utilized, the space of the display panel is wasted, and the high image resolution is difficult to be realized.

Therefore, it is desirable to provide a display panel and a display device capable of improving image resolution.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

In view of the small aperture ratio caused by the inevitable pixel arrangement structure in the related art, the incomplete utilization of the pixel definition layer, the waste of the space of the display panel, and the difficulty in achieving high image resolution, the inventor has made the following researches on the related art, referring to fig. 1, 2, and 3, fig. 1 is a schematic plane structure diagram of a display panel provided in the related art, fig. 2 is a schematic plane structure diagram of another display panel provided in the related art, fig. 3 is a schematic plane structure diagram of a pixel arrangement mode provided in the related art, and the pixel arrangement modes in fig. 1, 2, and 3 are arrangement modes commonly used in the related art. In fig. 1, three sub-pixels are a pixel repeating unit 010, and the pixel repeating unit 010 has a first sub-pixel 001, a second sub-pixel 002, a third sub-pixel 003, a first sub-pixel 001, and a second sub-pixelOpenings of the

pixels

002 and 003 are circular, a connecting line of centers of the first subpixel 001, the second subpixel 002 and the third subpixel 003 in the same pixel repeating unit 010 forms a triangle, the arrangement positions of the first subpixel 001, the second subpixel 002 and the third subpixel 003 in the two pixel repeating units 010 in the column direction Y are different, and it can be seen from fig. 1 that a region K1 between adjacent subpixels wastes space, the space of the region K1 is large, but no subpixel is arranged, so that the pixel arrangement mode in fig. 1 cannot realize high image resolution. In fig. 2, four sub-pixels are a pixel repeating unit 010, one pixel repeating unit 010 has a first sub-pixel 001, a second sub-pixel 002 and two third sub-pixels 003, openings of the first sub-pixel 001, the second sub-pixel 002 and the third sub-pixels 003 are circular, a region K2 between the first sub-pixel 001 and the second sub-pixel 002 and between the two third sub-pixels 003 causes space waste, and the region K2 has a large space but is not provided with any sub-pixel, so the pixel arrangement of fig. 2 can not realize high image resolution. FIG. 3 is an enlarged view of the pixel arrangement, and the sub-pixels in FIG. 3 are exemplified by Pentile arrangement, assuming that the width of the second sub-pixel 002 in the row direction X is 10 μm, the redundant length of the sub-pixel during deposition is 10 μm (the length of the non-opening area), and the sub-pixel length is 40 μm, as shown in FIG. 3, the area of the hollow area K3 surrounded by three sub-pixels approximates to the triangle area 50um with the base length and the height both being 10um ² (ii) a While the effective area of a single sub-pixel is about: 10 × 40=400um ² Therefore, the effective area wasted in one pixel unit is about: 50/(400 × 3) =4.2%. In summary, the pixel arrangement in the related art wastes space, and it is difficult to realize high resolution.

In view of the above, the present invention provides a display panel and a display apparatus for realizing high image resolution of the display panel, and the detailed embodiments of the display panel and the display apparatus are described below.

In fig. 6, the third subpixel 2003 is illustrated as an L-shaped structure, and the second subpixel 2002 is illustrated as a rectangle, in the structure in fig. 6, similarly, the second subpixel 2002 and the third subpixel 2003 are disposed around the first subpixel 2001, the first subpixel 2001 is disposed in a half-surrounded space 3000 formed by the L-shaped structure of the third subpixel 2003, and the first subpixel 2001 is disposed in a space between the second subpixel 2002 and the third subpixel 2003, so that space waste of a position other than the opening A2 is less, the area of the opening A1 of the subpixel is maximally increased, the space utilization rate of the display panel 100 is increased, and the image resolution of the display panel 100 is increased. In fig. 7, the second subpixel 2002 is in an L-shaped structure, the third subpixel 2003 is in a rectangular shape, the first subpixel 2001 is located in a half-surrounded space 3000 formed by the L-shaped structure of the second subpixel 2002, and the first subpixel 2001 is arranged in a space between the second subpixel 2002 and the third subpixel 2003, so that the waste of a position space other than an opening A2 is less, the area of an opening A1 of the subpixel is increased to the maximum, the space utilization rate of the display panel 100 is increased, and the image resolution of the display panel 100 is increased. It should be noted that the first sub-pixel 2001 may also be partially located in the semi-enclosed space 3000, which is not shown in the figure.
