Embodiment Construction

[0068] In the field of display technology, curved screen display panels are more and more widely used. figure 1 It is a schematic diagram of an AMOLED screen body and a glass cover in the bonding stage in the related art, as shown in figure 1 As shown, a suction cup 1 is used to fix the curved glass cover 2 , and then a silicone pad 3 is used to press the flat AMOLED screen 4 and the glass cover 2 to realize the bending of the edge of the AMOLED screen 4 . However, in the bonding process of the current curved screen display panel, since the glass cover is a curved surface, after pressing the flat AMOLED screen and the glass cover, due to the uneven force on the AMOLED screen as a whole, it is easy to appear on the curved surface. Fit bubbles, and because of insufficient bonding pressure, it is easy to make the optical glue and the glass cover insufficiently bonded, resulting in poor bonding, especially when the AMOLED screen is bonded to the large curvature glass cover or mult...

Abstract

The invention provides a cover plate, a display panel and a preparation method of the display panel, and relates to the technical field of display, in order to solve the technical problem that an existing curved surface cover plate is poor in attachment, the cover plate is applied to the display panel, the display panel is provided with a plane area and a curved surface area which are connected with each other, and the cover plate is provided with a plane part and a to-be-bent part which are connected with each other. The cover plate comprises at least two layers of flexible cover bodies which are mutually overlapped, and a hot melt adhesive layer is arranged between every two adjacent flexible cover bodies; and the hot melt adhesive layer at least covers the flexible cover body in the to-be-bent part. According to the invention, the cover plate and the display module can be tightly attached, and the use performance of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a cover plate, a display panel and a method for preparing the display panel. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panels have been widely used in various electronic products due to their advantages such as self-illumination, wide viewing angle, and fast response. Among them, with the development of flexible display panel technology and full-screen , The flexible AMOLED curved screen display panel has become the vane of the mobile phone industry. [0003] In the preparation process of the curved screen display panel, the flexible AMOLED curved surface display panel is realized by the curved surface bonding technology in the module stage, that is, the curved surface cover plate and the AMOLED screen body are pressure bonded in a vacuum environment. Before bonding, the glass cover plate It is a curved surface, and ...
