A method for full bonding of a curved screen and a flat display module and an integrated screen

Abstract

The invention discloses a curved screen and flat panel display module full-lamination method, which comprises the following steps: designing and manufacturing a frame, fixing a frame-pasting curved screen and the frame through a positioning fixture, injecting liquid optical cement, putting a flat panel liquid crystal display module, fixing through the positioning fixture to form an integrated screen, putting the positioning fixture and the integrated screen into a heating device and carrying out heating curing, removing the positioning fixture and the integrated screen out of the heating device after completing the above steps, dismounting the positioning fixture, removing spilled cement residue at the edge of the frame and completing lamination. The invention also discloses a curved screen and flat panel display module full-laminated integrated screen prepared according to the above processing method. By arranging the frame between the curved screen and the flat panel liquid crystal display module, lamination of a curved-surface product is converted into traditional flat-panel type lamination. The operation steps are simple. Investment in equipment and fixture is less. Batch production is convenient to realize.

Description

technical field [0001] The invention relates to the field of optical full bonding, in particular to a method and device for full bonding of a curved screen and a flat display module. Background technique [0002] The curved display has a beautiful curved appearance and a wide viewing angle, and the curved curved display conforms to the spherical characteristics of the human eyeball, which can eliminate visual distortion at the edge of the screen, make every point on the screen reach the same distance from the eyes, and create a natural and comfortable environment. Perceptual experience. With the gradual maturity of technology, curved displays are widely used in mobile phones, notebooks, TVs, etc., and may become the mainstream choice of future users, with broad market prospects. important. [0003] At present, the so-called lamination methods of screens and display modules in the industry can be divided into non-full lamination and full lamination. The non-full lamination...

Problems solved by technology

The disadvantage is that air bubbles are easily generated during the bonding process, and the tiny air bubbles that cannot be found during bonding may expand with time. In order to avoid affecting the yield of the bonded product due to air bubbles, it is necessary to use an autoclave or a vacuum centrifuge. degassing

Since optical tape or UV glue cannot be reworked, most of the defective products produced by lamination can only be scrapped, which increases the cost pressure of lamination

In addition to the complex process and large investment in equipment, the existing bonding technology for curved screens and flat display modules also requires the flexibility and thermal bending characteristics of the display module, such as the "flexible display device" with application number 201420227027.X Curved surface 3D bonding system" requires the display device to be a flexible display device, and the application number is 201510127000.2 "A fully bonded curved surface touch display screen and its manufacturing process" requires "putting the OLED display on a pre-laminated part Natural bending and shaping on the mold with the same hot bending shape”
