Embodiment 1

[0044] See figure 2 and image 3, the backplane 10 provided in this embodiment includes a base material 11 , a protective film 12 and a release film 13 . The substrate 11 is sandwiched between the protective film 12 and the release film 13 . The substrate 11 includes a first part 111 and a second part 112 , and the stiffness of the second part 112 is greater than that of the first part 111 . The first part 111 and the second part 112 are spliced ​​to form the base material 11 .

[0045] In this embodiment, the thickness of the first portion 111 is equal to the thickness of the second portion 112 . The first part 111 adopts polyimide (PI), and the material of the second part 112 is selected from polyethylene terephthalate (PET), optical material COP, SRF material, and polyurethane (PU) any of the It can be understood that, in other embodiments, the materials of the first part 111 and the second part 112 can also adopt other configurations, as long as the stiffness require...

Embodiment 2

[0055] See Figure 8 The structure of the backplane 10 provided in this embodiment is substantially the same as the structure of the backplane 10 provided in Embodiment 1, except that the first part 111 and the second part in this embodiment 112 varies in thickness. The thickness of the second portion 112 is greater than that of the first portion 111 , and the material of the first portion 111 is the same as that of the second portion 112 .

[0056] Specifically, in this embodiment, the second portion 112 has a thickness ranging from 70 μm to 100 μm, and the first portion 111 has a thickness ranging from 10 μm to 50 μm.

[0057] Preferably, the thickness of the second part 112 is 90 μm, and the thickness of the first part 111 is 20 μm-40 μm.

[0058] Preferably, the thickness of the second portion 112 may be twice the thickness of the first portion 111 .

[0059] The difference between the structure of the backplane 10 provided in this embodiment and the structure of the ba...

Embodiment 3

[0066] The structure of the backplane 10 provided in this embodiment is substantially the same as the structure of the backplane 10 provided in Embodiment 2, except that the material of the first part 111 is different from that of the second part 112 , the specific diagram can be found in Figure 9 and Figure 10 .

[0067] Specifically, in this embodiment, the first part 111 is made of polyimide (PI), and the material of the second part 112 is selected from polyethylene terephthalate (PET), optical material COP, SRF material, and any one of polyurethane (PU). It can be understood that, in other embodiments, the materials of the first part 111 and the second part 112 can also adopt other configurations, as long as the stiffness requirement is met.

[0068] The structure of the display module 100 provided in this embodiment is substantially the same as that of the display module 100 provided in Embodiment 2, except that the materials of different parts of the backplane 10 ar...

Abstract

The invention discloses a display module and a manufacturing method thereof.The display module comprises a bending area, the display module comprises a display panel and a back plate arranged on one side of the display panel, the back plate comprises a base material, and the base material comprises a first part and a second part; and the second part is close to the bending area of the display module relative to the first part, and the stiffness of the second part is larger than that of the first part. According to the display panel, the backboard is designed, the stiffness of the end, close to the bending area, of the backboard is effectively enhanced, and therefore the collapse problem caused by insufficient stiffness of the backboard is effectively solved, and the display panel is prevented from generating cracks and even being broken.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module and a manufacturing method thereof. Background technique [0002] Flexible display products have gradually become a new trend in the market. In order to improve the bending / bending performance of flexible display products, the industry generally adopts the method of thinning the backplane. For example, in folding display products, the ultra-thin backplane is used to replace the traditional relatively thick backplane. However, when the thickness of the backplane is reduced, its stiffness will decrease accordingly. After the bending operation, the end of the backplane is prone to collapse due to insufficient stiffness in the bending area near the display module. , resulting in cracks or even breakage of the display panel due to the collapse of the back plate. Contents of the invention [0003] The present invention provides a display module and a manufacturing...
