Display device and preparation method thereof

Abstract

The embodiment of the invention provides a display device and a preparation method thereof, and relates to the technical field of display. The amount of optical cement is controlled to avoid infirm attachment and cement overflow. The display device comprises a display module, a to-be-attached part stacked on the light emitting side of the display module, and the optical cement, wherein the to-be-attached part comprises a visible area and a frame area surrounding the visual area, and the optical cement is arranged between the display module and the to-be-attached part; the optical cement is used for making the display module attached to the to-be-attached part, and the orthographic projection, on the plane where the to-be-attached part is located, of the optical cement covers the visible area; a first cement collecting groove area is formed in the frame area; the surface of the side, close to the optical cement, of the first cement collecting groove area is provided with a first cementcollecting groove; the orthographic projection, on the plane where the first cement collecting groove area is located, of the edge of the optical cement is located in the first cement collecting groove area. The display device is used for display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a method for preparing the display device. Background technique [0002] The display device is used in portable mobile terminals, such as tablet computers, smart phones, notebook computers and other electronic products, and the display device mainly includes a display module and a cover plate. [0003] With the continuous development of electronic products, users have higher and higher requirements for electronic product screens, and consequently, higher and higher requirements for the bonding process between the display module and the cover plate. [0004] At present, the following methods are used for lamination: one is the glue lamination process, which has the advantage of using less materials, but the light transmittance of the display device will deteriorate after lamination. And the way of attaching only one round (square shape) along the fra...

Problems solved by technology

[0005] However, liquid optical adhesive (LOCA) has strong fluidity, and it is difficult to control the amount in the lamination process. A small amount will cause poor bonding, and a large amount will cause glue overflow.
