[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0025] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.
[0026] See also Figures 1 to 5 As shown, the embodiment of the present application provides a liquid crystal display module 10 for preventing LCD from cracking, including CG11, OCA12, FOG component 13, BL14 and composite foam 15.
[0027] The FOG assembly 13 includes an upper POL 131 , an LCD-CF 132 , an LCD-TFT 133 , a lower POL 134 , and an FPC 135 and an IC 136 .
[0028] In the embodiment of the present application, a composite foam 15 is arranged in the Z direction of the single-layer area 1331 of the LCD-TFT, and a clearance position 152 is arranged in the composite foam 15 at the position of the IC136. It should be understood that the clearance position 152 is used to provide space to accommodate the IC136. For example, the Z direction is the direction of the single-layer area 1331 of the LCD-TFT facing the CG11. The composite foam 15 arranged in the Z direction can reduce the force in the direction of deformation shearing of the single-layer area 1331 of the LCD-TFT during the mechanical experiment, and play a protective role.
[0029] The above-mentioned liquid crystal display module 10 for preventing LCD cracking, based on the sandwich structure formed by the upper POL131 and the lower POL134, can buffer the single-layer area 1331 of the LCD-TFT in the Z direction by adding a composite foam 15 in the Z direction to prevent the LCD from cracking.
[0030] In some embodiments, the composite foam 15 includes a composite hard foam layer 151 and a graphene layer 153, and the hard foam layer 151 is provided with an avoidance position 152 at the position of IC 136. The graphene layer 153 can play a cooling role at the position of IC 136 to prevent the temperature at the position of IC 136 from rising too high and affecting the experimental performance.
[0031] As an example, the hard foam layer 151 and the single-layer area 1331 of the LCD-TFT are bonded by an adhesive.
[0032] The above-mentioned liquid crystal display module 10 for preventing LCD from cracking can not only prevent LCD from cracking, but also avoid excessive temperature rise at the position of IC136 by adding composite foam 15 in the Z direction of the single-layer area 1331 of LCD-TFT.
[0033] In some embodiments, the edge size of the composite foam 15 is indented by 0.1 mm with respect to the edge of the LCD.
[0034] In other embodiments of the present application, an electronic device is provided, comprising a liquid crystal display module 10 for preventing LCD cracking provided by any of the above embodiments. As an example, the electronic device is a mobile phone or a vehicle-mounted display device.
[0035] In summary, the liquid crystal display module 10 and electronic device for preventing LCD cracking provided by the embodiment of the present application, based on the sandwich structure formed by the upper POL 131 and the lower POL 134, can buffer the single-layer area 1331 of the LCD-TFT in the Z direction by adding a composite foam 15 in the Z direction to prevent the LCD from cracking; and can also play a cooling role through the graphene layer 153 to avoid excessive temperature rise at the IC 136 position and affect the experimental performance. In this way, the stability of the extreme condition test of the mechanical reliability performance experiment of the whole machine module can be effectively improved, the progress of the client experimental test can be accelerated, the cost can be saved, and the confirmation progress of the end customer of the product can be accelerated, and time can be gained for the introduction of mass production.
