Problems solved by technology

However, in order to achieve better bending ability and mitigation effect, MS usually has a pattern design in the bending area, that is, many holes or grooves will be formed in the bending area, which will inevitably lead to the upper OCA in the hole area. sag downwards, forming a step difference, which causes wrinkles on the upper display panel, which affects the display effect; on the other hand, with continuous bending during use, the OCA adhesive layer will be squeezed into the cavity, making the OCA Decreased adhesion, greatly increasing the risk of film peeling

Abstract

The application discloses a flexible display module, a preparation method thereof and a flexible display device. The flexible display module comprises a metal sheet, a first adhesive layer, a back plate, a second adhesive layer, and a display panel. A plurality of through holes are formed in the metal sheet at least in a bending area; the first adhesive layer is arranged on the metal sheet and completely fills the holes in the metal sheet; the back plate is arranged on the first adhesive layer; the second adhesive layer is arranged on the back plate; and the display panel is arranged on the second adhesive layer. The lower part of the first adhesive layer is designed into the special shape which completely fills the holes in the metal sheet, so that the risk that the upper display panel wrinkles and the display module layer is stripped can be effectively reduced, and the reliability of the folding function of the display module is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible display module, a manufacturing method thereof, and a flexible display device. Background technique [0002] Flexible display technology is an important trend in the development of AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode) mobile phones, and major panel manufacturers are in the process of intensive development. Among them, since the end of 2018, several companies have publicly released folding display devices, which can provide users with a larger display screen when in use, and can be folded when not in use, occupying a small storage space , has been widely sought after by consumers. [0003] In the existing foldable display module, a buffer layer and a protective layer such as BP (Back plate, back plate) and MS (Metal sheet, metal sheet) are usually arranged under the display panel. Among them, the se...
