Embodiment 1

[0033] Such as figure 2 As shown, it is a schematic structural diagram of the foldable display module provided in Embodiment 1 of the present application. The foldable display module includes a flexible display panel 201, the front of the flexible display panel 201 is a display surface, and the back of the flexible display panel 201 is a non-display surface. The non-display surface side of the flexible display panel 201 is sequentially provided with a flexible supporting layer 202 and a heat dissipation layer 203 from top to bottom, and the display surface side of the flexible display panel 201 is sequentially provided with a touch panel from bottom to top. 204 , a polarizer 205 , a flexible cover 206 , and a protective film 207 . Moreover, two adjacent film layers are bonded to each other through the adhesive material layer 208 .

[0034] In this embodiment, the thickness of the flexible supporting layer 202 may be 300 microns. Specifically, the thickness of the flexible ...

Embodiment 2

[0050] Such as image 3 As shown, it is a schematic structural diagram of the foldable display module provided in Embodiment 2 of the present application. The structure of the foldable display module in this embodiment is the same / similar to the structure of the foldable display module in the first embodiment above, the difference is that in this embodiment, the flexible supporting layer 202 in the folding area A is thinned. The way is to facilitate the patterned thinning of folding, that is, the flexible supporting layer 202 of the folding area A is provided with non-equal thickness, and the thickness of the flexible supporting layer 202 corresponding to the folding area A is determined by the The middle part of the folding area A decreases toward both sides.

[0051] Specifically, the foldable display module is folded inwardly. The part of the flexible supporting layer 202 corresponding to the folding area A and the rest are continuous film layers, and the part of the flex...

Embodiment 3

[0055] Such as Figure 4 As shown, it is a schematic structural diagram of the foldable display module provided in the third embodiment of the present application. The structure of the foldable display module in this embodiment is the same / similar to the structure of the foldable display module in the first embodiment above, the difference is that in this embodiment, the flexible supporting layer 202 in the folding area A is thinned. The way is to facilitate patterned thinning of the folding, that is, the thickness of the flexible supporting layer 202 corresponding to the folding area A decreases from the middle of the folding area A to both sides.

[0056] Specifically, the part of the flexible supporting layer 202 corresponding to the folding area A and the rest are continuous film layers, and the part of the flexible supporting layer 202 corresponding to the folding area A includes a first arc surface 202c and a second arc surface 202c. surface 202d, the first arc surface ...

Abstract

The invention provides a foldable display module. The foldable display module comprises a folding area and non-folding areas located on the two sides of the folding area; the foldable display module comprises a flexible display panel and a flexible supporting layer arranged on the back of the flexible display panel; and the thickness of the flexible supporting layer ranges from 150 micrometers to1000 micrometers, and the thickness of the portion, corresponding to the folding area, of the flexible supporting layer is smaller than that of the portion, corresponding to the non-folding areas, ofthe flexible supporting layer. Accordingly, by adopting a single film layer obtained after thinning treatment is conducted on the folding area to replace the mainstream back plate-foam-metal supporting layer stacking design on an existing foldable device, the material and manufacturing cost of the existing foldable device is effectively lowered.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a foldable display module. Background technique [0002] OLED (Organic Light Emitting Diode, organic electroluminescent display) has become one of the research hotspots in the field of flexible display due to its excellent performance such as fast response speed, wide viewing angle, high brightness, low power consumption and anti-bending characteristics. At present, due to material and technical bottlenecks, small-radius dynamic folding flexible displays have problems such as film peeling, scratches, wrinkles, and poor pen and ball drop performance. All mainstream panel makers are trying to improve these problems by optimizing the display panel stack design. The main improvement method is to add functions such as backplate, foam, and metal sheet to the non-display surface of the panel. layer. Such as figure 1 As shown, the dynamic folding flexible display adds three...
