Problems solved by technology

When the flexible OLED screen is impacted by external force, or undergoes repeated bending, curling or laser lift-off (LLO), the inside of the screen is easily affected by stress and strain, especially for the array substrate, where the metal wiring, inorganic layer and OLED materials are prone to cracking, causing screen display failure

Abstract

The invention discloses a display panel, which has a bending area and a non-bending area connected with the bending area; the display panel includes an array substrate; the array substrate includes a plurality of first pixel areas arranged in parallel to each other into multiple rows and arranged in the bending area; several second pixel regions are arranged in parallel to each other in multiple rows and arranged in the non-bending region; and a plurality of flexible connection regions are used to connect the adjacent first pixel regions and are The first pixel area and the second pixel area are connected, wherein there is a slot in each flexible connection area, and an organic photoresist layer is filled in the slot. In the display panel and display device of the present invention, a slot is provided in each flexible connection area of ​​the bending area, so that there is an inorganic layer slot between two adjacent rows of pixel areas in the bending area, and the two rows of pixels The separation and the filling of the organic photoresist layer in the slots effectively relieve the stress of the corresponding inorganic layers or metal wirings in the display panel, especially in the array substrate.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a display panel and a display device. Background technique [0002] With the development of display technology, centered on OLED display technology, the development and application of a new generation of display technology is in full swing, and has been gradually applied to many fields, such as wearable devices such as smart bracelets, smart watches, VR (Virtual Reality (virtual reality) equipment, mobile phones, e-books and e-newspapers, televisions, personal portable computers, etc. The future of display is OLED, and the future of OLED is flexible display. The current development of "flexible display" technology is just the beginning, and what we have seen is only the tip of the iceberg. With the rapid development of emerging electronic products and the Internet of Things, flexible display technology is clearly the development direction of future electronic products. [...
