[0006] in Figure 1a Because the bending starting position 101 of the 101 is not covered with the protective glue 102, there will be a sudden change in stress during bending, resulting in a kink, which will lead to direct failure of the circuit. Figure 1b The protective glue 102 coated on the display area will affect the display effect of the edge of the display area

Abstract

The invention provides a method for manufacturing a flexible display panel, comprising forming a flexible substrate on a carrier substrate; forming a display device layer on the flexible substrate; cutting the flexible substrate; A film layer; coating a protective glue on a bending start position at the junction of the display area and the bending area of ​​the flexible substrate; removing the film layer; and removing the flexible substrate from the The above-mentioned carrier substrate is detached, thereby avoiding corners at the starting position of bending or poor display effect at the edge of the display area, so as to improve the quality, yield and reliability of the display panel.

Description

technical field [0001] The invention relates to a manufacturing method of a display panel, in particular to a manufacturing method of a flexible display panel. Background technique [0002] With higher requirements for display devices, the frame of the display screen is designed to be smaller and smaller to obtain a better visual experience. Early manufacturers usually reduce the border area of ​​the display area through design and material optimization to achieve the effect of narrow borders. In recent years, due to the development of flexible display screens, the narrow frame technology has been developed to reversely bend the connection area between the display area and the driving circuit board to obtain a narrower or even borderless display screen. The connection area is called the bending area . [0003] Usually, protective glue needs to be coated on the film layer in the bending area. The protective glue not only protects the film layer and prevents the film layer f...
