Problems solved by technology

[0004] At present, the first thing that affects the bonding yield is the bubbles generated during the bonding process. The bubbles will affect the optics and the appearance of the entire screen, which will seriously cause the film to peel off when the screen is bent, so the bonding bubbles are not allowed.
In addition, the thickness of the adhesive and film materials currently used for lamination are relatively thick, and the flexibility of the material itself is limited, which is not suitable for bending with a small radius of curvature.

Embodiment 2

[0065] Such as Figure 1 to Figure 6 As shown, an AMOLED panel 1 , encapsulation layer 3 and functional layer 4 are provided, similar to the AMOLED panel 1 , encapsulation layer 3 and functional layer 4 in the existing display screen. After providing such AMOLED panel 1, encapsulation layer 3 and functional layer 4, it is necessary to bond the AMOLED panel 1, encapsulation layer 3 and functional layer 4 together. All of them are coated on the lower surface of the encapsulation layer and the functional layer, or a layer of adhesive material is completely coated on the upper surface of the AMOLED panel and the encapsulation layer, but the disadvantages of such an arrangement have been described in the first embodiment above. I won't go into details here.

[0066] Therefore, in order to overcome the adverse effects caused by the original bonding method, the present invention is to arrange a number of adhesive material units at intervals on the AMOLED panel 1, the encapsulation l...

Abstract

The invention relates to the field of semiconductor light-emitting devices, in particular to a manufacturing method for a display screen and the display screen. Adhesive material units which are distributed at intervals are adopted and then attached in a staggered mode, appropriate adhesive materials are selected during early-stage setting, the interval between every two vertical adjacent rubber material units is regulated so that different attaching structures can be obtained, bubbles in attachment space formed after attachment are reduced, the buckling stress can be reduced so that flexible folding display can be better facilitated, adverse effects of the shrinkage effect of the adhesive materials on display devices are effectively eliminated, and the product yield is improved.

Description

technical field [0001] The invention relates to the field of semiconductor light emitting devices, in particular to a method for preparing a display screen and a display screen. Background technique [0002] At present, AMOLED has been widely used in mobile devices. Compared with traditional LCD, it has the following advantages: first, the AMOLED display screen is very thin, and the touch layer can be integrated in the screen, which is more advantageous for ultra-thin phones; second, AMOLED is self-illuminating, a single pixel does not work when displaying black, and has the characteristics of low power consumption when displaying dark colors; third, AMOLED can be made into a flexible screen, which is less prone to damage than LCD screens with glass substrates; fourth, it has a wide color gamut , can reach 110% NTSC, the color that cannot be accurately reproduced on the offloaded LCD can be expressed on the AMOLED; fifth, it has high contrast, theoretically the contrast can ...
