Abstract

The invention provides a flexible display module which comprises a plurality of functional layers, wherein the plurality of functional layers are divided into a plurality of functional groups, each functional group comprises two adjacent functional layers, and the two functional layers in at least one functional group are bonded in an adsorption mode. According to the flexible display module provided by the invention, the bonding between the two functional layers included in at least one functional group is changed from the original OCA layer bonding mode to the adsorption mode, so that the risk that the adjacent functional layers of the flexible display module are stripped due to the failure of the OCA layer is reduced or even completely eliminated, and the yield of the flexible display module is improved. Due to the adsorption mode, natural and non-adhesive bonding can be generated between the functional layers, and the bonding is reversible, so that when certain functional layers need to be replaced, the replacement of the corresponding functional layers can be completed by adjusting the adsorption force between the functional layers, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display module and a folding and rolling method thereof. Background technique [0002] In recent years, the Organic Light-Emitting Diode (OLED) display module has been recognized by the industry as the display module with the most development potential due to its advantages of wide viewing angle, high color gamut and low power consumption, and the development of flexible OLED display modules (referred to as flexible display modules) have gradually become the goal of industry development. [0003] Adjacent functional layers in existing flexible display modules are generally bonded by Optically Clear Adhesive (OCA) layers. Therefore, the solid OCA layer in flexible display module products accounts for a relatively large proportion, so that in practical applications, flexible When the display module is bent or curled, it is very easy to cause failure of the OCA layer, w...
