Display device, display module and manufacturing method thereof

Abstract

The invention relates to a display module, which comprises an OLED panel and a heat dissipation film positioned on the back surface of the OLED panel, wherein the OLED panel can be reversely bent to be connected with a flexible circuit board positioned on one side of the heat dissipation film far away from the OLED panel; an adhesive layer is arranged on one surface of the heat dissipation film far away from the OLED panel; the adhesive layer consists of a plurality of sub-adhesive layers arranged at intervals; and the adhesive layer can be deformed to absorb forces generated when the flexiblecircuit board is in pressed connection on the OLED panel. The invention further relates to a display device and a manufacturing method of the display module. Due to the arrangement of the adhesive layer formed by a plurality of the sub-adhesive layers arranged at intervals, the adhesive layer is easy to deform, and most pressing energy is absorbed through the deformation of the adhesive layer, and thus the energy transmitted to the heat dissipation film is reduced, and the deformation of the heat dissipation film is reduced, so that the bad phenomenon of AMOLED die printing is effectively andreliably improved.

Description

technical field [0001] The invention relates to the technical field of display product production, in particular to a display module, a display device and a method for manufacturing the display module. Background technique [0002] Compared with the traditional liquid crystal display used in most mobile phones, AMOLED (Active-matrix organic light emitting diode) has a wider viewing angle, a higher refresh rate and a thinner size, and has become a smartphone The darling of the globalization wave and the first choice for flagship products. However, due to module assembly factors, FPC (flexible circuit board) needs to be folded and pressed. After FPC is pressed, AMOLED is prone to deformation due to its excellent flexibility in the pressed part of the FPC device area, and poor mold printing can be found under strong light. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a display module, a display device and a...
