Problems solved by technology

[0004] In the existing flexible display screen, when the glass substrate and the flexible screen body are peeled off, because the material of the flexible screen body is relatively soft and the thickness is relatively thin, the signal line is prone to breakage at the position of the driver chip circuit, resulting in poor function of the flexible screen body

Abstract

The invention discloses a flexible display, a manufacturing method thereof and a piece of electronic equipment. The flexible display comprises a flexible display screen, a driving chip and a supporting device, wherein the flexible display screen comprises a flexible substrate that comprises a display area and a binding area; the driving chip is bound to the binding area; the supporting device covers the flexible substrate, and the supporting device located at the position of the binding area is provided with an opening. As the supporting device covers the entire flexible substrate, the flexible display and the manufacturing method thereof and the electronic equipment disclosed by the invention increase the strength of the bonding region, prevent the problem of poor function of the flexiblescreen body caused by that the signal lines are broken during peeling, reduce the attachment process of the support film, and make the flexible display thinner at the same time.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display, a manufacturing method thereof, and electronic equipment. Background technique [0002] The flexible display screen has the obvious advantage of flexible deformation, and can be bent and folded at a large angle. The use of this type of screen can effectively improve the portability of the device. As flexible display technology becomes more and more mature, flexible display screens are gradually integrated into mobile devices such as mobile phones and tablets to become the main tools of our lives. [0003] Existing flexible display screens generally include a glass substrate, a flexible screen body and a driver chip circuit that are sequentially combined. The flexible screen used for image display includes pixel units densely arranged on the flexible screen and signal lines arranged around the pixel units and routed along the edge of the flexible screen. The...
