Problems solved by technology

However, since the OLED display is just a display, its screen structure has limited strength, and the entire screen is emitting light and generating heat at the same time, so a large module adhesive needs to be attached to the back of the OLED display to enhance the screen. Anti-drop and uniform heat, heat dissipation effect
However, due to the relatively large module adhesive, air bubbles are likely to be generated during attachment, and if bubbles are generated, structural interference will be formed, affecting the appearance, and the module adhesive is not easy to reprocess, so the entire attachment process is labor-intensive and time-consuming. thereby increasing the manufacturing cost

Embodiment 1

[0040] Such as figure 1 As shown, this embodiment discloses a module adhesive 20 for adhering to the back of the display module 10. The module adhesive 20 includes an adhesive layer 21 and a composite structure 22, and the composite structure 22 passes through The adhesive layer is adhered to the back of the display module 20, and

[0041] Such as figure 2 As shown, the module adhesive 20 also includes a plurality of vent holes 28 , and the vent holes 28 penetrate through the adhesive layer 21 and the composite structure 22 in sequence.

[0042] The usual tape or sticker pasting process, due to the area of ​​the tape or sticker, cannot completely discharge the air between the tape or sticker and the surface to be pasted in time during the pasting process, resulting in a gap between the pasted tape or sticker and the pasting surface. There are air bubbles. A conventional method is to wet the surface to be pasted with an easy-drying liquid (such as a surfactant solution), so ...

Embodiment 2

[0058] Such as Figure 6As shown, this embodiment discloses an organic light emitting diode display module, including the module adhesive 20 in the above embodiment; it may also include:

[0059] The display screen 30 includes a display surface and a back surface facing away from the display surface;

[0060] Wherein, the module adhesive 20 is adhered to the back of the display screen 30 .

[0061] In a preferred embodiment, the outer contour shape of the module adhesive 20 is adapted to the contour shape of the display screen 30 .

[0062] In the above technical solution, the module adhesive 20 should protect the display screen 30 as much as possible without affecting the display effect of the display screen 30, so the size of the module adhesive 20 is often not smaller than the size of the display screen 30 . In addition to the protective function, the module back glue 20 can also add other materials or structures, so that the module back glue 20 has other functions besid...

Abstract

The invention discloses a module back adhesive for adhering to the back surface of a display module. The module back adhesive comprises an adhesive layer, a composite structure which is adhered to theback side of the display module through the adhesive layer, a plurality of vent holes which sequentially penetrate the adhesive layer and the composite structure, an organic light emitting diode display module comprising the above back adhesive and a display screen which comprises a display screen and a back surface facing away from the display surface, and the module back adhesive adheres to theback surface. According to an organic light emitting diode display module formed by the above technical scheme, a fragile display screen is protected by using the module back adhesive, at the same time, bubbles are not formed on the back surface of the formed organic light emitting diode display module, and the problems of mechanism interference, appearance affection, time and labor consumption and the like generated by the bubbles in the organic light emitting diode display module are avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a module adhesive and an organic light emitting diode display module. Background technique [0002] With the continuous improvement of people's quality of life, various mobile terminals have become people's favorite devices, especially mobile terminal products with large screens and high-resolution displays are especially popular, because users have more and more requirements for display screens High, more new technologies have been invested in mobile terminal displays, such as OLED (Organic Light-Emitting Diode, organic light-emitting diode) display technology, due to its self-illumination, wide viewing angle, almost infinitely high contrast, low power consumption, The advantages of extremely high response speed and easy realization of flexible display have gradually become the mainstream of mobile terminal display screens. As a new generation of display methods, they have grad...
