Embodiment Construction

[0033] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0034] It should be noted that "on", "formed on" and "arranged on" mentioned in this article may mean that one layer is directly formed or set on another layer, or that a A layer is indirectly formed or disposed on another layer, ie there are other layers between the two layers. In this document, unless otherwise specified, the term "on the same layer" used means that two layers, parts, members, elements or parts can be formed by the same patterning process, and that the two layers, parts, members, Elements or parts are g...

Abstract

The invention discloses a display module, a manufacturing method and a display device.The display module comprises a display panel which comprises a first face and a second face which are oppositely arranged; the display panel comprises a first face and a composite film arranged on the first face, the composite film comprises a bonding layer, a buffer layer and a heat dissipation layer which are stacked in the direction from near to far away from the display panel, the buffer layer comprises a buffer body and a plurality of open grooves formed in the side, close to the heat dissipation layer, of the buffer body, and each open groove is filled with a heat conduction material; and the second surface is a light emitting side of the display panel. According to the embodiment of the invention, the heat conduction material is arranged in the slot of the buffer layer, so that the unit area of the heat conduction material is effectively reduced on the basis of ensuring the heat dissipation function, the cohesion of the heat conduction material in the unit area is improved, and the problem that the composite film is easy to bulge during subsequent maintenance in the prior art can be solved; the manufacturing process of the composite film is simplified, and the manufacturing cost of the display module is saved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module, a manufacturing method and a display device. Background technique [0002] Organic light emitting diode (OLED) display modules are widely used in various display devices due to their advantages such as self-illumination, wide viewing angle, wide color gamut, foldability and bendability. [0003] In the prior art, an OLED display module generally includes a display panel, and a composite film located on a side opposite to the light-emitting side of the display panel. The composite film can buffer the stress acting on the display panel and have a certain protective effect on the display panel. However, the composite membrane is prone to bulging during subsequent maintenance, thereby increasing the maintenance cost. Contents of the invention [0004] In order to solve at least one of the above problems, a first embodiment of the present invention provides a di...
