Problems solved by technology

[0003] As the lower frame of the display panel becomes narrower, the bending radius of the display panel needs to be smaller and smaller. When the bending radius is reduced, the adhesive layer used to bond the bending area of ​​the display substrate also needs to be smaller and smaller. Thin, under such a thickness, the adhesive layer will be difficult to be absorbed by the adsorption equipment, and it is prone to problems such as wrinkles after adsorption

Embodiment Construction

[0040] In order to illustrate the present application more clearly, the present application will be further described below in conjunction with the embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present application.

[0041] Compared with traditional screens, flexible displays are not only lighter and thinner in size, but also lower in power consumption than original devices, which helps to improve the battery life of the device. At the same time, based on its bendable and flexible characteristics, Its durability is also much higher than that of previous screens, reducing the probability of accidental damage to equipment. Therefore, the technology for flexible display screens needs to be improved day by day.

[0042] At present, the low...

Abstract

The embodiment of the invention discloses an adhesive tape and a preparation method of a display panel. The adhesive tape comprises a release film, a colloid, first foam and second foam, wherein the first side surface of the colloid is attached to the first side surface of the release film; and the first foam and the second foam are located on the two sides of the colloid and fixedly connected tothe first side surface of the release film. According to the adhesive tape, the release film is attached to the surface of the colloid, so the adhesive tape can be conveniently adsorbed by adsorptionequipment, and the colloid is prevented from being polluted when moved; and the adhesive tape is easily adsorbed through arrangement of the first foam and the second foam, and wrinkles of the adhesivetape can be effectively prevented.

Description

technical field [0001] This application relates to the field of display technology. More specifically, it relates to a preparation method of an adhesive tape and a display panel. Background technique [0002] In recent years, high screen-to-body ratio has become the mainstream design solution in the display field and is favored by consumers. Since the flexible display OLED has the advantages of being foldable, rollable, thin and portable, and can be produced by low-cost processes such as inkjet printing, it provides more design ideas for end products. Utilizing the bendability of the flexible substrate, the effect of narrow frame can be achieved by bending the pixel lead-out line to the position of the external circuit. After the display panel is bent, the upper and lower surfaces opposite to each other after bending are bonded together by means of double-sided adhesive tape. [0003] As the lower frame of the display panel becomes narrower, the bending radius of the disp...
