Problems solved by technology

The driving circuit is generally composed of multiple cascaded shift register units. Therefore, in the current display panel, the area where the driving circuit is located cannot be used for display, resulting in a large frame area of ​​the display panel, which limits the screen size of the display panel. increase in proportion

Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology and are used to increase the screen-to-body ratio of the display panel. The base substrate included in the display panel includes a main display area and a first auxiliary display area. The main display area includes a first light emitting device and a first pixel circuit electrically connected. The first auxiliary display area includes a driving circuit and a second light-emitting device, and the second light-emitting device is located on a side of the driving circuit away from the substrate; the driving circuit is electrically connected to the first pixel circuit. The density of the second light emitting device is greater than or equal to the density of the first light emitting device.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. 【Background technique】 [0002] Organic Light-Emitting Diode (OLED) display panels are widely used in the field of display technology due to their many advantages, such as active light emission, high contrast ratio, and no viewing angle limitation. Moreover, with the development of display technology, narrow-frame display screens have gradually attracted people's attention due to their simplicity and large viewing area. [0003] Currently, an OLED display panel generally includes a plurality of sub-pixels located in a display area and a driving circuit located in a non-display area for driving these sub-pixels to charge. The driving circuit is generally composed of a plurality of cascaded shift register units. Therefore, in the current display panel, the area where the driving circuit is located cannot be used for display, re...
