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 present invention discloses a display panel. The display panel comprises a bending region and a non-bending region connected with the bending region, and the display panel further comprises an array substrate. The array substrate comprises: a plurality of first pixel regions which are mutually arranged in parallel in multiple lines and arranged in the bending region; a plurality of second pixel regions which are mutually arranged in parallel in multiple lines and arranged in the non-bending region; and a plurality of flexible connection regions configured to connect with adjacent first pixel regions and connect with the first pixel regions and the second pixel regions, wherein each flexible connection region is internally provided with a slot, and each slot is filled with an organic photoresist layer. According to the invention, the slots are arranged in the flexible connection regions of the bending region to form an inorganic layer slot between two adjacent lines of pixel regionsin the bending region to separate from each two lines of pixel regions, and the slots are filled with the organic photoresist layers so as to effectively relieve the stress of each inorganic layer ormetal wiring corresponding 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. [...
