Problems solved by technology
[0002]Restricted by the nature of the material itself and the process, super-sized display screens, such as display wall products, are generally realized by splicing, and the key of the splicing display screen is The problem is how to solve the problem that the seams cannot be displayed and the display screen produces dark strips
[0003] In the prior art, since the frame width of a single OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display screen is relatively large, even if the connection structure is bent to The opposite side of the light-emitting surface, but the width of the frame of the OLED display still cannot meet the requirements of visually eliminating the stitching seam

Abstract
The embodiment of the invention provides a flexible substrate, a display screen and a display device. According to the flexible substrate, a first electrode and a second electrode of an organic light-emitting unit are led out to the side, away from the organic light-emitting layer, of the flexible substrate through a lead-out structure, so that the flexible substrate can be connected with a driving circuit through the lead-out structure; a fan-out line, a binding area, a film pasting and bending process buffer area of a flexible circuit board and the like do not need to be arranged in the formed frame area of the display screen, and the frame width can be greatly reduced; when the display screen is a spliced screen, the width of the frame is greatly reduced, so that the difference betweenthe width of a splicing seam and the distance between sub-pixels is small, the splicing seam is visually eliminated, and the display effect of the spliced display screen is improved; and the lead-outstructure is arranged in a dark area, so that an erosion path of water and oxygen to the organic light-emitting unit is not provided, and the water and oxygen invasion performance of the flexible substrate is ensured.
Description
technical field [0001] The present application relates to the field of display technology, in particular, the present application relates to a flexible substrate, a display screen and a display device. Background technique [0002] Due to the nature of the material itself and the limitation of the process, super-sized display screens, such as display wall products, are generally realized by splicing, and the key problem of the splicing display screen is how to solve the problem that the display screen cannot be displayed at the splicing seam. The problem with dark bars. [0003] In the prior art, since the frame width of a single OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display screen is large, even if the connection structure is bent to the opposite side of the light-emitting surface, the width of the frame frame of the OLED display screen remains the same. The requirement to visually eliminate seams cannot be met. Contents of the invention [0...
