Flexible folding screen and manufacturing method thereof

Abstract

The invention provides a flexible folding screen with good bending characteristics and a manufacturing method thereof. The flexible folding screen includes: a non-bending area located at both ends of the flexible folding screen; a bending area located at the The middle of the flexible folding screen; the non-bending area and the bending area include a substrate, an array film layer circuit, a flat layer, an anode film layer, a cathode film layer, a light-emitting layer, and a pixel defining layer , a plurality of separation units, an inkjet printing layer, wherein the anode film layer and the light-emitting layer located in the bending area are configured in a curved shape, and when the flexible folding screen is bent, the bending area A bending stress is released and deformation occurs in the same direction as a bending direction.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible folding screen with good bending properties and a manufacturing method thereof. Background technique [0002] OLED displays have high pixel density and excellent bendability. At the current level of OLED production, high pixel density means more device structure arrangements and more process flows. With the current development of OLEDs, dynamic curved screens have become a hot topic. However, due to the limitation of technology maturity, there are still many problems in the folding screen, one of which is that the mechanical action of the folding screen causes the TFT, evaporated film layer, packaging film layer, etc. in the bending area to break, thereby damaging the device or even causing the Aborted, curved screen display failure. [0003] The structure of a traditional OLED display includes a substrate, an array film layer circuit, a flat layer, an anode film layer, a cathode...

However, due to the limitation of technology maturity, there are still many problems in the folding screen, one of which is that the mechanical action of the folding screen causes the TFT, evaporated film layer, packaging film layer, etc. in the bending area to break, thereby damaging the device or even causing the Aborted, curved screen display failure

[0003] The structure of a traditional OLED display includes a substrate, an array film layer circuit, a flat layer, an anode film layer, a cathode film layer, a light emitting layer, a pixel defining layer, a plurality of separation units, an inkjet printing layer , each layer is arranged in a flat manner, but when the OLED display is folded, the flat design is likely to cause cracks or even breakage in each layer, which will affect the display effect of the display
