Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, and in particular to an anti-static in-cell liquid crystal display assembly. Background Technology

[0002] Incell is a technology that embeds touch panel functionality into liquid crystal pixels. It is a type of screen bonding technology. By embedding touch sensors into the liquid crystal display layer, Incell technology achieves the fusion of touch and display, making the screen thinner and lighter, reducing the air gap between the traditional touch screen and the display screen, and improving the display effect and touch sensitivity.

[0003] Currently, while existing anti-static in-cell LCD screen components can quickly conduct static electricity away along a preset direction when static electricity is generated in specific areas of the LCD, such as from the square-shaped ITO conductive layer to the ground line, effectively preventing static electricity accumulation and thus solving the problem of static whitening and improving the anti-static performance of the product, they cannot shield against external static interference while timely discharging static electricity. As a result, when facing complex and ever-changing static environments, the LCD screen is still susceptible to external static electricity intrusion, affecting its operational stability and reliability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot discharge static electricity in a timely manner while shielding against external static interference, resulting in the LCD screen still being susceptible to external static intrusion. Therefore, this invention proposes an anti-static In-cell LCD screen component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An antistatic in-cell LCD panel assembly, comprising:

[0007] The LCD screen body includes an upper polarizer, an upper glass substrate, a color filter, a liquid crystal layer, a touch film, a lower glass substrate, and a lower polarizer.

[0008] The LCD screen body is provided with a shielding conductive component, which is used to shield and discharge static electricity on the LCD screen body.

[0009] In one possible design, the shielding conductive component includes a shielding film wrapped around the main body of the liquid crystal screen. Aluminum foil film is attached to the bottom perimeter of the shielding film. Contact points are fixedly provided on the diagonal sides of the bottom of the aluminum foil film. Conductive lines are fixedly provided on one side of each of the two contacts. The aluminum foil film is in electrical contact with the contacts, and the contacts are in electrical contact with the conductive lines.

[0010] In one possible design, the upper polarizer is the top layer, the upper glass substrate is below the upper polarizer, the color filter is below the upper glass substrate, the liquid crystal layer is below the color filter, the touch film is below the liquid crystal layer, the lower glass substrate is below the touch film, and the lower polarizer is below the lower glass substrate, forming the bottom layer.

[0011] In one possible design, the upper polarizer, upper glass substrate, color filter, liquid crystal layer, touch film, lower glass substrate, and lower polarizer are all covered with the same edge-sealing adhesive.

[0012] In one possible design, the touch film is embedded inside and fused with the liquid crystal layer.

[0013] In one possible design, an FPC flexible board is provided on one side of the main body of the LCD screen, and the FPC flexible board is electrically connected to the lower glass substrate.

[0014] In this application, when it is first used, the main body of the LCD screen is composed of an upper polarizer, an upper glass substrate, a color filter, a liquid crystal layer, a touch film, a lower glass substrate, and a lower polarizer. After assembly, the same edge-sealing adhesive is applied to the outside of the LCD screen main body to fix the structure of each layer and prevent dust and moisture from entering, while facilitating subsequent bonding and assembly.

[0015] A shielding film is wrapped around the assembled LCD screen body. The shielding film can be used to shield external electromagnetic interference and discharge static electricity from the LCD screen body. Aluminum foil film is attached to the bottom four sides of the shielding film. The aluminum foil film has good conductivity, which helps static electricity to be conducted from the shielding film to the aluminum foil film. Contact points are fixedly set on the bottom diagonal sides of the aluminum foil film. The contact points absorb static electricity on the aluminum foil film and connect the conductive wire to the contact point. The conductive wire can be connected to the grounding terminal. The conductive wire is used to discharge the static electricity absorbed by the contact point to the grounding terminal, preventing static electricity accumulation from damaging the LCD screen.

[0016] An FPC flexible board is set on one side of the LCD screen body, and the FPC flexible board is electrically connected to the lower glass substrate. The FPC flexible board has flexibility and foldability, which facilitates the connection and layout of the LCD screen with other electronic devices.

[0017] This utility model has the following beneficial effects:

[0018] By incorporating a shielded conductive component, this invention not only effectively shields against external electrostatic interference, preventing it from adversely affecting the internal circuitry and components of the LCD screen, but also promptly discharges static electricity generated on the LCD screen body, preventing static electricity accumulation from damaging the LCD screen. This enhances the antistatic performance of the LCD screen, ensures its operational stability and reliability, and extends its service life. Attached Figure Description

The shielding conductive component is used to shield and discharge static electricity on the LCD screen body 1, thereby improving the antistatic performance of the component.

[0028] The upper polarizer 101 is placed as the top layer, followed by the upper glass substrate 102, color filter 103, liquid crystal layer 104, touch film 105, lower glass substrate 106 and lower polarizer 107 in sequence. The touch film 105 needs to be embedded inside the liquid crystal layer 104 and fused with it so that the two are tightly combined to form a whole.

[0029] The upper polarizer 101, upper glass substrate 102, color filter 103, liquid crystal layer 104, touch film 105, lower glass substrate 106 and lower polarizer 107 are all covered with the same edge-sealing adhesive 2. The edge-sealing adhesive 2 needs to be applied evenly to ensure tight adhesion between the layers, while preventing dust and moisture from entering, and facilitating subsequent bonding and assembly.

[0030] A shielding film 3 is applied and wrapped around the outer perimeter of the LCD screen body 1. The shielding film 3 must have good conductivity and shielding performance to effectively shield external electrostatic interference. During the wrapping process, it is necessary to ensure a tight fit between the shielding film 3 and the LCD screen body 1 to avoid gaps. An aluminum foil film 4 is applied around the bottom perimeter of the shielding film 3. The aluminum foil film 4 must be tightly fitted with the shielding film 3 to ensure good electrical contact. The function of the aluminum foil film 4 is to enhance the shielding effect and serve as a channel for static electricity discharge. Contact points 5 are fixedly provided on the diagonal sides of the bottom of the aluminum foil film 4. The contact points 5 can be fixed to the aluminum foil film 4 by welding or pasting, ensuring electrical contact with the aluminum foil film 4. A conductive wire 6 is fixedly provided on one side of each of the two contact points 5. The conductive wire 6 can be electrically connected to the contact point 5 by welding or crimping, and conduct static electricity to an external grounding device. The length and specifications of the conductive wire 6 can be selected according to actual needs to ensure that static electricity can be smoothly discharged and convenient for installation and connection to the grounding point.

An FPC flexible board 7 is provided on one side of the LCD panel body 1. The FPC flexible board 7 is electrically connected to the lower glass substrate 106. The FPC flexible board 7 is used to transmit the LCD panel's signals and power. It is necessary to ensure that the connection between it and the lower glass substrate 106 is firm and reliable. During the connection process, a dedicated connector or welding method can be used to connect, and the conductivity of the connection point must be good.
