Description

Technical Field

[0001] The utility model relates to the fields of industrial, vehicle-mounted and other touch screens, and in particular to an anti-MURA display module structure. Background Art

[0002] Since the edges of the display area in industrial and automotive display screens need to be supported by frames or other components, the display screens become uneven when subjected to force, resulting in various marks. This phenomenon is called display MURA. The display MURA phenomenon easily causes the display module to be defined as a defective product. In the prior art, the method for improving the display MURA is not only costly, but also complicated in operation. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.

[0017] Figure 1 This is a schematic diagram of an anti-MURA display module structure in one embodiment of the utility model;

[0018] Figure 2 for Figure 1 Another structural schematic diagram of an anti-MURA display module structure;

[0019] Figure 3 for Figure 1 Schematic diagram of a backlight module structure of an anti-MURA display module structure DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1 , Figure 2 and Figure 3A MURA-proof display module structure 10 includes: a cover plate 100, a display screen 200 and a backlight module 300 which are arranged in sequence, the display screen 200 includes an outer frame 210 and a display area 220, the cover plate 100 is covered on the surface of the display screen 200, the cover plate 100 includes a non-visible area 110 and a visible area 120, the edge of the visible area 120 is set inward relative to the edge of the display area 220, the backlight module 300 is set on a side away from the surface of the display screen 200, the backlight module 300 includes a supporting layer 310, the supporting layer 310 is arranged opposite to the outer frame 210, and the supporting layer 310 is used to provide support for the display screen 200.

[0022] It should be noted that by appropriately shrinking the visible area 120 in the cover plate 100, the area of ​​the display area 220 of the display screen 200 that is prone to MURA phenomenon is blocked, especially the side of the IC chip and FPC binding position where the force is more serious, and the MURA phenomenon in this area is more obvious. Therefore, the visible area 120 of the cover plate 100 needs to be further retracted and blocked on this side, so that the display effect presented around the visible area 120 is the same; at the same time, a support layer 310 that can provide supporting force is provided behind the outer frame 210 of the display screen 200 to reduce the squeezing force generated when the user presses the display screen 200, thereby reducing the risk of MURA phenomenon in the display screen 200. The support layer 310 in this embodiment is made of a soft material with weak viscosity and relatively large compression. Therefore, while providing supporting force, the support layer 310 avoids having a large squeezing force on the display screen 200, which leads to serious MURA phenomenon.

[0023] See also Figure 2 In one embodiment, the backlight module 300 further includes a backlight glue frame 320 , a groove 321 is defined in the backlight glue frame 320 , the support layer 310 is disposed in the groove 321 , and the support layer 310 and the groove 321 are bonded by strong adhesive glue.

[0024] It should be noted that the backlight glue frame 320 is provided with a groove 321, so that the support layer 310 has a space for setting. Since a soft material with low viscosity is used in this embodiment, the support layer 310 and the groove 321 need to be bonded by a strong adhesive glue, so that the support layer 310 is fixed on the backlight glue frame 320 to avoid the support layer 310 310 The support force of the display screen 200 changes due to unstable adhesion, which makes the MURA phenomenon serious.

[0025] See also Figure 1 In one embodiment, the compression amount of the support layer 310 is 0.1 mm. This setting is to enable the support layer 310 to provide greater support force for the display screen 200 while reducing the pressure on the display screen 200, so that the interference fit between the support layer 310 and the display screen 200 needs to be controlled at 0.1 mm.

[0026] Please refer again Figure 1 In one embodiment, the cover plate 100 is made of tempered glass, which is not easily deformed, thereby preventing the MURA phenomenon from being serious due to the pressure exerted on the display screen 200 by the bending of the cover plate 100 during the use of the display module.

[0027] Please refer again Figure 1 In one embodiment, black ink is screen-printed on the non-visible area 110. This is to provide a shielding effect for the area prone to MURA phenomenon.

[0028] Please refer again Figure 1 In one embodiment, the cover plate 100 and the display screen 200 are bonded together by optical adhesive. This configuration is to ensure that the cover plate 100 and the display screen 200 are bonded together while maintaining the clarity of the display screen 200.

[0029] See also Figure 3 In one embodiment, the support layer 310 includes a first support horizontal bar 311, a second support horizontal bar 312, a first support vertical bar 313 and a second support vertical bar 314 forming a U-shape, a first limiting groove 315 is arranged at the upper end of the first support vertical bar 313, a second limiting groove 316 is arranged at the upper end of the second support vertical bar 314, the first limiting groove 315 and the second limiting groove 316 are arranged relatively parallel, the first support horizontal bar 311 is connected to the first limiting groove 315 and the second limiting groove 316, a first limiting portion 317 is arranged at the lower end of the first support vertical bar 313, a second limiting portion 318 is arranged at the lower end of the second support vertical bar 314, the first limiting portion 317 and the second limiting portion 318 are arranged relatively parallel, and the second support horizontal bar 312 is connected to the first limiting portion 317 and the second limiting portion 318.

[0030] It should be noted that the two ends of the first support cross bar 311 are connected to the first limiting groove 315 and the second limiting groove 316, and the second support cross bar 312 is connected to the first limiting portion 317 and the second limiting portion 318. This arrangement makes it difficult for the first support cross bar 311 and the second support cross bar 312, which are subjected to greater force, to change their positions, making the overall structure of the support layer 310 more stable, further improving the reliability of the anti-MURA display module structure.

[0031] 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.
