Problems solved by technology

The four-curved screen faces more serious problems in the production process than the hyperboloid, among which the risk of film breakage is particularly prominent
How to solve the problem that the stress concentration encountered in the bending and bonding process of the four-curved surface causes the film layer to break and cause the screen to fail to emit light has become a difficulty in packaging technology.

Abstract

The invention provides a flexible display module, a display device and a manufacturing method of the display device. The flexible display module comprises a display area and a peripheral area surrounding the display area; the peripheral area is provided with a first retaining wall and a second retaining wall; a first buffer structure is arranged between the first retaining wall and the second retaining wall; and the first buffer structure is sequentially covered with a first inorganic packaging layer, an organic packaging layer and a second inorganic packaging layer.

Description

technical field [0001] The present application relates to the field of display and touch control, and in particular to a flexible display module, a display device and a manufacturing method of the display device. Background technique [0002] A known hyperbolic screen on the market mainly uses a flexible screen to generate a certain curvature on both sides of the screen, so that the screen can be extended on both sides of the device, and has the effect of display and touch. The hyperboloid screen has gradually become the mainstream product in the high-end market, and another four-curved screen is gradually being developed. The four-curved mobile phone screen can set a certain curvature on all four sides, so that the screen is curved on each side. The four-curved screen faces more serious problems in the production process than the double-curved screen, among which the risk of film breakage is particularly prominent. How to solve the problem that the stress concentration en...
