Problems solved by technology

However, there are currently problems of insufficient and uneven diffusion of point-like colloids, which in turn leads to the existence of pores and bubbles inside the planar colloids formed by diffusion.
Moreover, the existence of pores and air bubbles provides a channel for external substances such as water and oxygen to invade the screen body in the bending area, causing great hidden dangers to the reliability of the screen body

Abstract

The invention provides a display panel, a pressing device and a preparation method of the display panel, and the display panel comprises a screen body which comprises a display part, a bending part and an extension part which are connected in sequence, and the display part and the extension part are oppositely arranged at an interval; wherein the bending part comprises a first surface and a second surface, the first surface and the second surface are arranged oppositely, and the second surface faces a gap between the display part and the extension part; the protective glue at least covers the first surface and / or the second surface, and the surface of the side, away from the bent part, of the protective glue is provided with a concave-convex structure; wherein the concave-convex structure is formed by pressing the protective glue by a pressing jig. Through the design mode, the probability of existence of pores and bubbles in the protection glue can be reduced.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a display panel, a pressing device and a preparation method of the display panel. Background technique [0002] In order to achieve a full screen effect, the non-display area of ​​the screen body is generally bent so that the frame size of the display panel is as small as possible. However, after the non-display area of ​​the screen body is bent, the bent area of ​​the screen body is very prone to cracks due to stress. [0003] In order to reduce the occurrence of cracks, protective glue is generally coated on the surface of the bending area of ​​the screen body at present. Moreover, the current protective glue is generally formed by dot-like glue coating, and the dot-like colloid formed by dot-like glue will automatically diffuse to form a planar colloid. However, there are currently problems of insufficient and uneven diffusion of point-like colloids, w...
