Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, in particular to a HUD liquid crystal display module. Background Art

[0002] At present, in order to improve the antistatic ability of the HUD liquid crystal display module, a conductive cloth is usually pasted on the iron frame and continuously connected to the grounding copper leakage area on the FPC board. In this way, the iron frame is connected to the ground, so that the static electricity received on the iron frame can be quickly released through the grounding copper leakage area of the FPC board.

[0003] In the related art, since the FPC board needs to be bent and the bending angle is relatively large, the conductive cloth may be broken, resulting in the inability to release static electricity. Summary of the Utility Model

[0007] The thickness range of the conductive sponge is 1.0 mm to 1.1 mm.

[0008] The vertical distance from the FPC board to the first iron frame ranges from 0.90 mm to 0.95 mm.

[0009] The film material component further includes a second iron frame, and the second iron frame is disposed on the first iron frame.

[0010] The film material component further includes a first glass substrate, a first polarizer and a colloid. The first glass substrate is disposed on the first polarizer, the first polarizer is disposed on the colloid, and the colloid is disposed on the first iron frame.

[0014] The membrane material assembly further includes a protective glue, and the protective glue is disposed on the chip.

[0015] A gap is provided between the conductive sponge and the FPC board.

[0016] Compared with the prior art, the present utility model has at least the following advantages:

[0017] By providing a copper leakage area near the first iron frame of the FPC board, then attaching the conductive sponge in the copper leakage area, and making the conductive sponge conduct with the first iron frame, the static electricity is thus introduced into the ground. In addition, since the area near the first iron frame of the copper leakage area is a non-bending area, there is no risk of breakage. BRIEF DESCRIPTION OF THE DRAWINGS

For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] In order to improve the antistatic ability of the HUD liquid crystal display module, a conductive cloth is usually attached to the iron frame and extended all the way to the grounding copper leakage area on the FPC board. In this way, the iron frame is connected to the ground, so that the static electricity received on the iron frame can be quickly released through the grounding copper leakage area of the FPC board. In the related art, since the FPC board needs to be bent and the bending angle is relatively large, the conductive cloth may be broken, resulting in the inability to release static electricity.

[0024] In view of the above problems, an embodiment of the present application provides a HUD liquid crystal display module, which can release static electricity instead of attaching a conductive cloth.

[0025] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0027] It should be noted that the copper leakage area 310 is not in the bending area of the FPC board 300, and there is no risk of breakage, and it is close to the first iron frame 210. By setting the conductive sponge 100 to be in contact with the first iron frame 210, static electricity can be transmitted through the conductive sponge 100 to the copper leakage area 310 for release.

[0028] Please refer to Figure 1 , in an embodiment, the thickness range of the conductive sponge 100 is 1.0 mm to 1.1 mm. Specifically, the vertical distance range from the FPC board 300 to the first iron frame 210 is 0.90 mm to 0.95 mm.

[0029] It should be noted that the conductive sponge 100 has a certain amount of compression after assembly to ensure sufficient contact between the conductive sponge 100 and the first iron frame 210 and the copper leakage area 310.

[0030] Please refer to Figure 1, in one embodiment, the film component 200 further includes a second iron frame 220, and the second iron frame 220 is disposed on the first iron frame 210.

[0031] It should be noted that the second iron frame 220 is installed on the first iron frame 210 by a snap-fit method.

The first glass substrate 230 is disposed on the first polarizer 240, the first polarizer 240 is disposed on the colloid 250, and the colloid 250 is disposed on the first iron frame 210.

[0033] It should be noted that the first polarizer 240 plays a role in polarizing light, and the colloid 250 is double-sided adhesive.

[0034] Please refer to Figure 1 , in one embodiment, the film component 200 further includes a second glass substrate 260, and the second glass substrate 260 is disposed on the first glass substrate 230.

[0036] Please refer to Figure 1 , in one embodiment, the film component 200 further includes a second polarizer 270, and the second polarizer 270 is disposed on the second glass substrate 260.

[0042] Please refer to Figure 1 , in one embodiment, there is a gap between the conductive sponge 100 and the FPC board 300.

[0043] It should be noted that the distance from the conductive sponge 100 to both sides of the FPC board 300 is 0.5 mm to prevent the conductive sponge 100 from extending beyond the area of the FPC board 300 after attachment. In addition, to avoid interference between the conductive sponge 100 and the protective adhesive 290, the conductive sponge 100 is 0.8 mm away from the side edge of the first glass substrate 230.
