Abstract

The present application provides a display module and a preparation method thereof. The display module includes: a display panel including at least one first curved portion; a support layer arranged under the display panel, and the support layer is opposite to the first The curved part is provided with a groove; the heat dissipation buffer layer is arranged under the supporting layer, and the heat dissipation buffer layer is provided with a second curved part relative to the first curved part; the first adhesive layer is arranged on the supporting layer and the heat dissipation buffer layer; wherein, the side of the first glue layer away from the heat dissipation buffer layer is provided with a first protrusion, and the first protrusion is filled in the groove, so The side of the first adhesive layer close to the heat dissipation buffer layer is provided with a second raised portion, and the second raised portion is connected to the second bent portion, so that poor display can be avoided.

Description

technical field [0001] The present application relates to a display technology, in particular to a display module and a preparation method thereof. Background technique [0002] With the continuous improvement of people's requirements for full-screen, how to increase the screen-to-body ratio of the display has become an urgent problem to be solved. At present, the screen-to-body ratio of a display is usually increased by increasing the bending angle of the screen, such as waterfall screens and four-curved screens currently on the market. However, the greater the bending angle of the screen and the more the number of bending sides, the more vulnerable the encapsulation layer is to stress damage and cracks when the display panels are 3D bonded, resulting in poor display. Contents of the invention [0003] Embodiments of the present application provide a display module and a manufacturing method thereof, which can avoid poor display. [0004] An embodiment of the present ap...
