Problems solved by technology

When the heat dissipation film is attached to the curved surface of the four peripheral corners, the four corners are in a compressed state, and the heat dissipation film itself is not stretchable, and the excess heat dissipation film is easy to form wrinkles, so that air bubbles will appear between the heat dissipation film and the display screen. , and the wrinkles when the heat dissipation film is attached are likely to cause defects such as cracks on the display screen.

Abstract

The embodiment of the invention provides a display module. The display module comprises a display panel; the cover plate is arranged on the light emitting side of the display panel; the heat dissipation layer is arranged on the back side of the display panel; the back side deviates from the light emitting side; peripheral edge areas of the cover plate, the display panel and the heat dissipation layer are bent towards the back side of the display panel to form cambered surfaces matched with each other in shape; the display panel further comprises a plane part; the peripheral edge area of the display panel is arranged on the periphery of the plane part in a surrounding manner; at least part of an orthographic projection edge line of the display module on a plane where the plane part of the display panel is located is an arc line; and the heat dissipation layer is provided with a telescopic structure in the cambered surface area with the arc edge.

Description

technical field [0001] The embodiments of the present disclosure belong to the field of display technology, and in particular relate to a display module, a preparation method thereof, and a display device. Background technique [0002] At present, OLED flexible display devices that can be bent, folded and stretched are being actively developed. In the disclosed technology, the edge area on the display side of the display screen is set as a curved surface, and the corners of the display screen are set as rounded corners. A heat dissipation film is attached to the back of the display screen to conduct timely conduction and release of the heat when the display screen is displayed. When the heat dissipation film is attached to the curved surfaces of the four peripheral corners, the four corners are in a compressed state, and the heat dissipation film itself is not stretchable. , and the wrinkles when the heat dissipation film is attached can easily lead to defects such as crack...
