Abstract
Description
Technical Field
[0001] The utility model relates to the field of display module production and manufacturing, in particular to a display module structure. Background Art
[0002] In a display module, it generally includes a cover plate, a display screen and a backlight structure. The conduction of the display screen and the backlight structure is generally achieved by setting an FPC, that is, the FPC is bound to the display screen and the backlight structure. The display screen FPC in the display module is usually bent before shipment. Some products also require the addition of double-sided adhesive on the display screen FPC and the retention of the double-sided adhesive protective film for shipment. However, since the double-sided adhesive is located on the side close to the backlight after the FPC is bent, that is, the double-sided adhesive is between the display screen FPC and the backlight structure, it is impossible to observe whether the double-sided adhesive is missing or whether the protective film on the double-sided adhesive surface has fallen off. The missing double-sided adhesive or the falling off of the protective film will make it impossible for end customers to use it and affect production efficiency.
[0003] In view of the above, a display module structure is proposed, so that it is possible to directly observe whether the double-sided adhesive has any missing parts and whether the double-sided adhesive protective film has any falling-off problems. Utility Model Content

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a display module structure 10 includes: a cover plate 100, a display screen and a backlight structure 300, which are stacked in sequence; a display screen FPC (flexible circuit board) 210 is bound to the display screen, a double-sided adhesive attachment area is provided on the display screen FPC210, a double-sided adhesive 220 is attached to the double-sided adhesive attachment area, and a protective film 230 is attached to the side of the double-sided adhesive 220 away from the display screen FPC210, a first avoidance hole 211 is opened on the display screen FPC210, the first avoidance hole 211 is located on the double-sided adhesive attachment area, and a second avoidance hole 221 is also opened on the double-sided adhesive 220, and the first avoidance hole 211 is aligned with the second avoidance hole 221.
[0027] It should be noted that, usually, after the display screen FPC210 is folded to the back, the double-sided adhesive 220 and the protective film 230 are located between the display screen FPC210 and the backlight structure 300, making it impossible to directly observe whether the double-sided adhesive is missing or whether the protective film 230 falls off. Therefore, in the present utility model, by opening a first avoidance hole 211 on the display screen FPC210, and at the same time opening a second avoidance hole 221 on the double-sided adhesive 220, and aligning the first avoidance hole 211 with the second avoidance hole 221, it is possible to directly observe whether there is a protective film 230 through the first avoidance hole 211 and the second avoidance hole 221. If the protective film 230 is not seen, it can be determined that the double-sided adhesive 220 is missing or the protective film 230 on the double-sided adhesive 220 falls off, and rework is required to prevent defective products from flowing to end customers and affecting customer use. At the same time, it should be noted that when opening the first avoidance hole 211, it is necessary to avoid the wiring structure on the display screen FPC.
[0028] In one embodiment, a color printing layer is printed on the side of the protective film 230 facing the double-sided adhesive 220. The color printing layer can be easily identified by naked eyes.
[0029] In another embodiment, the protective film 230 is a color protective film. The protective film 230 can also be a colored protective film 230 directly, so that it can be quickly identified by naked eyes.
[0030] In one embodiment, the first avoidance hole 211 is in a square structure. The four corners of the first avoidance hole are in an arc angle structure, so that stress concentration at the corners can be avoided, which may cause the display screen FPC to tear. Similarly, the second avoidance hole is in a square structure, and the four corners of the second avoidance hole are in an arc angle structure.
[0031] In one embodiment, a tear handle 231 is provided on the protective film 230. The tear handle 231 facilitates tearing the protective film 230.
[0032] Furthermore, a device area is provided on the display screen FPC 210, and a device protection paper 212 is attached to the device area. The device protection paper 212 isolates and protects the components on the device area to prevent external dust or foreign matter from contaminating and damaging the components.
[0033] Furthermore, a backlight FPC 310 is bound to the backlight structure 300, the backlight FPC 310 is connected to the display screen FPC, and the backlight FPC is covered with a backlight FPC protection paper 311. The backlight FPC protection paper 311 isolates and protects the binding part on the backlight FPC.
[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
