Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display panels, in particular to an anti-static liquid crystal display panel. Background Art

[0002] The display screen commonly used in existing display modules is generally a liquid crystal display screen. The liquid crystal display panel in the liquid crystal display screen is usually composed of an upper glass and a lower glass with different functions bonded together by a frame glue. The box is filled with liquid crystal, and various circuit matrices are arranged on the lower glass. An electric field is formed by the circuit matrix, thereby controlling the rotation angle of the liquid crystal through the electric field and controlling the amount of light passing through to form different display images.

[0003] See also Figure 1 As shown, the existing liquid crystal display panel is usually cut into small panels from a large panel. In order to prevent static electricity from damaging the internal circuits of the liquid crystal display panel, it is necessary to set a static-conducting metal ring around each small panel unit on the large panel, and the metal rings on the adjacent small panel units on the left and right are connected by metal connecting wires, thereby forming a large static-discharging grid to release static electricity. However, when the large panel is cut into small panels, the metal connecting wires between the small panels will be exposed (the metal connecting wires extend to the edge of the small panel), so that a "channel" will be provided for external static electricity to be injected into the internal wiring of the liquid crystal display panel, causing certain static-electricity hazards. Utility Model Content

[0023] 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.

[0024] See also Figure 2 , Figure 3 and Figure 4 As shown, an anti-static liquid crystal display panel includes: a liquid crystal display panel body 10, an internal wiring area 100 is provided on the liquid crystal display panel body 10, an electrostatic metal ring 200 is provided around the periphery of the internal wiring area 100, an FPC500 (flexible circuit board) binding pad (pin; pad) is provided on the liquid crystal display panel body 10, the electrostatic metal ring 200 is connected to the FPC binding pad300, and the FPC binding pad300 is connected to a metal connecting wire 400, and the metal connecting wire 400 is used to connect the small panels on both sides of the liquid crystal display panel body 10 adjacent to each other; when the FPC500 is bound to the FPC binding pad300, an anti-static protective glue 600 is provided at the junction of the FPC500 and the edge of the liquid crystal display panel body 10, and the anti-static protective glue 600 partially covers the metal connecting wire 400 located near the edge of the liquid crystal display panel.

[0025] Please note that Figure 1As shown, it is a schematic diagram of an anti-static structure of an existing anti-static liquid crystal display panel in a large panel structure. In order to prevent static electricity from damaging the internal circuit a of the liquid crystal display panel, it is necessary to set a static-conducting metal ring b around each small panel unit on the large panel. The metal ring b is a GND (ground terminal) metal ring. The metal rings b on the adjacent small panel units on the left and right are connected by metal connecting wires c, thereby forming a large static discharge grid to release static electricity. However, when the large panel is cut into small panels, the metal connecting wires c between the small panels will be exposed (the metal connecting wires c extend to the edge of the small panel). In this way, it will provide a "channel" for external static electricity to be injected into the internal wiring of the liquid crystal display panel, causing certain static electricity hazards. Therefore, in the present invention, an electrostatic metal ring 200 is provided, and the electrostatic metal ring 200 is connected to the FPC binding pad300, so as to release static electricity; further, by providing a metal connecting wire 400 in the area where the FPC binding pad300 is provided on the liquid crystal display panel body 10, and connecting the metal connecting wire 400 to the FPC binding pad300, after the FPC500 is bound to the FPC binding pad300, an anti-static protective glue 600 can be provided at the junction of the FPC500 and the edge of the liquid crystal display panel body 10. The anti-static protective glue 600 can not only reduce the risk of damaging the edge of the liquid crystal display panel during the bending and assembly process of the FPC500, but also cover the metal connecting wire 400 at the edge, thereby avoiding the existence of a "channel" for static electricity to enter the liquid crystal display panel, thereby improving the anti-static effect.

[0026] Preferably, the antistatic protective glue 600 is a UV waterproof glue containing antistatic particles. That is, the antistatic protective glue 600 is arranged at the junction of the FPC 500 and the edge of the liquid crystal display panel body 10. Since the FPC 500 needs to be bent during assembly, adding the antistatic protective glue 600 here can not only reduce the risk of the FPC 500 damaging the edge of the liquid crystal display panel during the bending process, but also prevent water vapor from entering the FPC binding pad 300 to cause corrosion failure. At the same time, the metal connecting wire 400 at the edge is covered by the antistatic protective glue 600, so that the edge end of the metal connecting wire 400 is isolated from the outside world. At the same time, because the antistatic protective glue 600 contains antistatic particles, it can better prevent static electricity from entering from the exposed metal connecting wire 400, thereby improving the antistatic ability.

[0027] It should also be noted that when the LCD panel body 10 is in the uncut state, the metal connection lines 400 set on the FPC binding pad 300 connect the other small panels adjacent to the left and right sides, thereby forming a large electrostatic discharge grid to improve the electrostatic discharge efficiency. Furthermore, the end close to the FPC binding pad 300 is the bottom side of the LCD panel body 10. On the large panel, two cutting lines need to be set for the upper and lower rows of small LCD panels. Please refer to Figure 3 As shown, the first cutting line is to separate the upper and lower rows of small LCD panels, and the second cutting line is to cut off the metal connecting wires 400 outside the design area of ​​the small LCD panel. Then, the metal connecting wires 400 on both sides connected to the FPC binding pad 300 are exposed at the edge of the LCD panel body 10, so in order to prevent static electricity from entering the interior through the metal connecting wires 400, a layer of anti-static protective glue 600 is covered on the edge of the metal connecting wires 400 to play an anti-static role.

[0028] Specifically, the liquid crystal display panel body 10 includes an upper glass and a lower glass, the lower glass is arranged on one side of the upper glass, and the internal wiring area 100, the electrostatic metal ring 200, the FPC binding pad 300 and the metal connecting line 400 are respectively arranged on the lower glass.

[0029] Furthermore, the upper glass and the lower glass are bonded together into a box by means of frame glue.

[0030] In one embodiment, the bottom side of the lower glass extends away from the upper glass to form a binding protrusion, and the FPC binding pad 300 is arranged on the binding protrusion. The binding protrusion is a single-layer glass area, which is convenient for the subsequent binding of the FPC 500 and the IC chip. Furthermore, an IC chip binding area 700 is also arranged on the binding protrusion, and an IC chip is bound and arranged on the IC chip binding area 700.

[0031] Furthermore, the FPC 500 is connected to the FPC binding pad 300 by means of anisotropic conductive film (ACF) conductive adhesive. The ACF conductive adhesive has both unidirectional conductive function and adhesive fixing function.

[0032] Preferably, the FPC bonding pad 300 is a copper metal bonding pad.

[0033] Preferably, the thickness of the upper glass is 1.1 mm to 1.8 mm. For example, the thickness of the upper glass is 1.3 mm.

[0034] Preferably, the thickness of the lower glass is 1.1 mm to 1.8 mm. For example, the thickness of the lower glass is 1.3 mm.

[0035] 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.
