Problems solved by technology

[0003] As users have more and more demands on the flexible, bendable or folding performance of display terminal products, the requirements for the stability of the performance of flexible display products and the number of bending resistance are also getting higher and higher, especially for the driving of the bending area. The design of array film layer and light emitting unit brings more and more challenges

Abstract

The embodiment of the invention provides a display panel and a display device. An extra organic buffer layer is arranged on a substrate of the display panel; in a bent region, due to a concave-convexstructural design, the organic buffer layer comprises multiple "troughs" and "crests"; and devices having relatively large area proportions in a driving unit of the display panel are placed at the "crests" positions, thereby avoiding the problem of excessively high stress caused by the devices having the relatively large area proportions in bending operation. Meanwhile, all types of signal wires (patterned on a metal layer) with relatively low stress are arranged at the "troughs" positions. The devices and the signal wires are respectively arranged at the "troughs" positions and the "crests" positions of the organic buffer layer, so as to reduce the stress in the bent region.

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] At present, display technology has penetrated into every aspect of people's daily life, and correspondingly, more and more materials and technologies are used in display screens. Today, mainstream display screens mainly include liquid crystal display screens and organic light-emitting diode display screens. Among them, due to the self-luminous performance of the organic light-emitting diode (Organic Light-Emitting Diode) display, compared with the liquid crystal display, the most energy-consuming backlight module is omitted, so it has the advantage of being more energy-saving; in addition, the organic light-emitting diode display The screen is also flexible and bendable. By using a flexible substrate, multiple conductive layers are sequentially formed on the flexible substrate, including a thin-film...
