[0030] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] One embodiment of this application provides a display module structure that facilitates pressure holding detection, which will be referred to below. Figures 1-3 This application provides a detailed description of a display module structure that facilitates pressure holding testing, such as... Figure 1-3 As shown, an embodiment 1 of this application provides a display module structure for easy pressure holding detection, comprising:

[0033] Backlight module 100;

[0034] TFT glass 200 is bonded to the backlight module 100;

[0035] CF glass 300 is bonded to the TFT glass 200;

[0036] The cover glass 500 is bonded to the CF glass 300 using OCA adhesive 400;

[0037] The cover glass 500 includes a pressure-holding area 700, on which a pressure test paper 600 is provided.

[0038] In this embodiment, the pressure-holding area 700 is arranged around the visible area of ​​the display module structure.

[0039] In this embodiment, in order to ensure accurate testing, the pressure test area 601 of the pressure test paper 600 is entirely located on the pressure holding area 700. The pressure holding area 700 is provided with a pressure holding detection area, and the pressure test paper is placed on the pressure holding detection area. The width of the pressure holding detection area is greater than the width of the pressure test area 601 of the pressure test paper 600, and the length of the pressure holding detection area is greater than the length of the pressure test area 601 of the pressure test paper 600.

[0040] It can be understood that the pressure holding test area is any area in the pressure holding area that meets the above conditions.

[0041] In this embodiment, the pressure test paper 600 includes a protective layer, a pressure sensing layer, and a base layer stacked sequentially from top to bottom, including a pressure test area 601 and a tearing area 602.

[0042] The protective layer is usually made of materials such as polyester film, which mainly serves to protect the internal sensitive materials from the influence of the external environment, such as scratches and contamination. At the same time, it also enables the pressure test paper 600 to have good flexibility and abrasion resistance during use. The thickness is generally 10-20 micrometers.

[0043] The pressure-sensitive layer contains pressure-sensitive chemicals that change color when subjected to pressure. It is typically composed of microencapsulated colorants and developers, and has a thickness of 50-100 micrometers.

[0044] The base layer is typically made of paper or plastic film, which supports the pressure-sensitive coating in the middle, providing a certain strength and stability, and facilitating the use and storage of the pressure test paper 600. The thickness is 50-100 micrometers.

[0045] In this embodiment, the color-changing pressure of the pressure-sensitive layer is 20 N / cm. 2 That is, when the pressure on the pressure test paper 600 reaches 20 N / cm 2 The pressure-sensitive layer will change color when the pressure is applied, indicating that a pressure-holding process has been completed.

[0046] Understandably, the pressure test paper 600 can be selected with a matching color-changing pressure according to the pressure holding pressure in the actual pressure holding process.

[0047] In this embodiment, the pressure-sensitive layer will change to any one of the colors red, yellow, or blue when the pressure reaches the color-changing pressure.
