Problems solved by technology

In this way, a new problem will arise. The infrared light transmittance is greatly reduced by the influence of the wiring density in the backplane circuit, which cannot achieve the purpose of the current infrared detection and other functions.

Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] The shapes and sizes of the components in the drawings do not reflect the real scale, but are only intended to schematically illustrate the content of the present invention.

[0026] A display panel provided by an embodiment of the present invention, such as Figure 1A , Figure 2A with Figure 3A As shown, including the display area, the display area is divided into a first area aa and a second area bb, the first area aa and th...

Abstract

The invention provides a display panel and a display device. The display panel includes a display region which is divided into a first region and a second region. Both the first region and the secondregion have multiple pixel units. The pixel units include light emitting devices and pixel driving circuits for driving the light emitting devices. In the first region and the second region of the same area, the number of the pixel driving circuits in the first region is greater than the number of the pixel driving circuits in the second region. Because the number of the pixel driving circuits inthe first region is greater than the number of the pixel driving circuits in the second region under the condition that the first region and the second region are of the same area, the occupied area of the pixel driving circuits in the second region is reduced, and the transmittance of the second region can be improved. Therefore, a photosensitive device can be set on the back of the display panelcorresponding to the second region, the bezel space originally needing to be occupied by the photosensitive device is canceled, the screen-to-body ratio of the display screen is increased, and a slimbezel is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Due to its own characteristics, OLED display devices are widely used. At present, with the development of small and medium-sized display screens, terminal display products are developing in the direction of smaller and smaller appearance frames. The smart functions that need to be equipped, such as infrared sensing functions and other photosensitive elements, will take up most of the frame. In order to solve this contradiction, a more effective solution is to place photosensitive elements such as infrared sensors on the back of the display. In this way, a new problem will arise. The infrared light transmittance is greatly reduced due to the influence of the wiring density in the backplane circuit, which cannot achieve the purpose of the current infrared detection and other functions.
