Abstract

The invention relates to the technical field of displays and display adhesion. The invention relates to an Adhesion method based on a curved surface flexible screen. The adhesion method based on the curved surface flexible screen comprises the steps of providing a first panel with a curved surface and an optical thermoplastic adhesive film, tearing off the first release film of the adhesive film,attaching the adhesive film to the surface of the first panel, arranging a second panel, tearing off the second release film, attaching one side, opposite to the first panel, of the adhesive film to the second panel, carrying out hot pressing and defoaming treatment on the first panel and the second panel, and curing the joint of the first panel and the second panel. The display device is manufactured by the film adhesion method. The adhesive film provided by the invention can be quickly attached to the first panel and the second panel; according to the display device, bubbles generated in thehot pressing process of the adhesive film are eliminated, stress at the attaching position of the first panel and the second panel is absorbed, the adhesive film is prevented from rebounding, the first panel and the second panel are prevented from deforming, the attaching yield between the first panel and the second panel is increased, the display effect of the display device is improved, and theservice life of the display device is prolonged.

Description

technical field [0001] The invention relates to the technical field of display and display bonding, in particular to a bonding method based on a curved flexible screen and a display device. Background technique [0002] With the continuous development of science and technology, various types of electronic equipment have been gradually used in people's life, study and work. Curved screen and curved screen equipment are widely used due to their good operation and visual effects; for protection A display in an electronic device is usually provided with a protective panel on the surface of the display by pasting a film. [0003] Because the side of the curved screen is curved and has an R angle, during the film attachment process, the adhesive film and the curved screen are not fully bonded or the bonding strength of the adhesive film is low, resulting in air bubbles between the curved screen and the adhesive film, and the adhesive film is attached After the shape of the curved...
