Problems solved by technology

[0003] With the maturity of flexible OLED technology, there are more and more curved surface display products on the market; however, the lamination process of curved surface cover plate and flexible OLED in curved surface display OLED is complicated and the yield rate is low, and the gas in the curved edge area is difficult during lamination. discharge, it is easy to cause bad air bubbles, so optimizing the surface bonding process has become an urgent problem to be solved
[0004] In the curved display bonding process, there is a back plate bonding process. The back plate is bonded to the back of the flexible screen and then bonded to the curved cover plate. Because the back plate material is thick and hard, it will Severely affect the surface bonding effect, and easy to produce air bubbles

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0020] Such as figure 1 As shown, in the prior art, the back plate 11 is bonded to the back of the flexible OLED 12, and the thickness of the product increases after bonding; then the flexible OLED 12 bonded to the back plate 11 is bonded to the curved cover plate 13; The material stress at the bonding position is large, so the flexible OLED 12 is easily detached from the curved cover 13 at the bonding position of the curved edge, and air bubbles are generated...

Abstract

The invention discloses a backboard and an electronic device for a curved-display. The backboard includes a first region plate body and a second region plate body connected to each other, the first region plate body maintains a flat plate state when attached to a curved surface object, the second region plate body maintains a bent state when attached to a curved surface object, and the second region plate body is provided with a hollow or groove structure; the electronic device includes a cover plate with a curved portion and a flexible screen and the backboard attached to the cover plate, thefirst region plate body of the backboard is attached to a flat area of the flexible screen opposite to the cover plate, and the second area plate body of the backboard is attached to a curved area ofthe flexible screen opposite to the cover plate. The device can reduce the stress generated when the second region of the backboard fits the curved surface object, and prevent the generation of air bubbles during the bonding.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backplane for curved screens and electronic equipment. Background technique [0002] In the field of display technology, flat panel display technologies such as Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) have gradually replaced CRT (Cathode Ray Tube, cathode ray tube) displays. OLED display has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, flexible display and large-area full-color display, and many other advantages. It is recognized as the display device with the most development potential. [0003] With the maturity of flexible OLED technology, there are more and more curved surface display products on the market; however, the lamination process of curved surface cover plate and flexib...
