[0026] 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.

[0027] 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.

[0028] 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.

[0029] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0030] See also Figures 1 to 8 As shown, the embodiment of the present application provides a liquid crystal display module 10 with a retaining wall to prevent LCD cracking, including a FOG component 11 and a BL 12. The FOG component 11 includes an upper POL 111, an LCD-CF 12, an LCD-TFT 13, a lower POL 114, an FPC 115 and an IC 116, and the BL 12 includes a retaining wall structure 121.

[0031] In the embodiment of the present application, the side of the four sides of the lower POL114 that is on the same side as the IC116 is larger than the corresponding side of the LCD by a first dimension, and the remaining three sides of the four sides of the lower POL114 are larger than the corresponding sides of the LCD by a second dimension, the first dimension is larger than the second dimension, and the lower POL114 is provided with an avoidance position 1141 at the position of the IC116. This arrangement can avoid "hard-on-hard" interference collision between the glass and the edge of the casing, because the upper POL111 and the lower POL114 are both neutral soft rubber materials, thereby protecting the surroundings of the glass from being hit by hard objects. As an example, Figure 6 As shown, the first dimension is 0.2 mm and the second dimension is 0.1 mm.

[0032] In the embodiment of the present application, the inner side of the retaining wall structure 121 exceeds the edge of the lower POL 114. This arrangement can support and protect the single-layer area 1131 of the LCD-TFT and prevent the retaining wall structure 121 of the BL 12 from being broken due to displacement and impact caused by falling.

[0033] In some embodiments of the present application, the distance from the side of the upper POL111 on the same side as IC116 to IC116 is at least the third dimension, and the remaining three sides of the four sides of the upper POL111 are larger than the corresponding sides of the LCD by the second dimension, and the third dimension is larger than the first dimension. Such a setting can ensure a good lighting effect. As an example, Figure 6 As shown, the third dimension is 0.8 mm.

[0034] As an optional implementation of this embodiment, BL12 further includes a light shielding glue 122 disposed on the retaining wall structure 121, and the lower POL114 is bonded and connected to the light shielding glue 122. As an example, the light shielding glue 122 is in a square shape. As an example, BL12 further includes a backlight assembly 123, for example, the backlight assembly 123 includes a light bar or a light belt.

[0035] The above-mentioned liquid crystal display module 10 with retaining walls for preventing LCD cracking can avoid direct "hard collision" between the surrounding areas of the LCD and the retaining wall structure 121 of BL12 during mechanical experiments by optimizing the structural design of the upper POL111 and the lower POL114, thereby preventing the LCD from cracking and enhancing the protection of the LCD.

[0036] In some other embodiments of the present application, an electronic device is provided, comprising a liquid crystal display module 10 with a retaining wall for preventing LCD cracking provided by any of the above embodiments.

[0037] In summary, the liquid crystal display module 10 and electronic device with a retaining wall for preventing LCD cracking provided in the embodiment of the present application can prevent the LCD from directly hitting the retaining wall structure 121 of BL12 around the LCD, thereby preventing the LCD from cracking. This can effectively improve the stability of the extreme condition test of the mechanical reliability performance experiment of the whole machine module, speed up the progress of the client experimental test, save costs, and speed up the confirmation progress of the product terminal customers, thereby buying time for the introduction of mass production.

[0038] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
