[0003] When the touch screen is used in the actual environment, especially in a dry environment, the screen surface is prone to excessive static electricity. When the user touches the screen, local discharge will occur, affecting the user experience. Secondly, under the influence of static electricity, the screen is very easy to absorb the surrounding dust. The dust will adhere to the screen surface and enter the interior of the screen through its heat dissipation holes, sound holes and other pores. Not only will a layer of dirt film be formed on the surface of the screen, affecting the visual effect, but the dust entering the interior will change the impedance between the circuit board lines and reduce the insulation resistance of the device, thereby affecting the normal function of the tablet device and even causing electrical breakdown and short circuit accidents.

DETAILED DESCRIPTION

[0029] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] like Figure 1-7 As shown in the figure, it is an embodiment of the present invention. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a touch-sensitive flat panel display screen, comprising a display screen composed of a display screen housing 1 and a display screen panel assembly 2. The front side surface of the display screen housing 1 is provided with card slots on four sides, namely a first card slot 11, a second card slot 12, a third card slot 13 and a fourth card slot 14. A seal is clamped in each card slot, namely a first seal 111 in the first card slot 11, a second seal 121 in the second card slot 12, a third seal 131 in the third card slot 13 and a fourth seal 141 in the fourth card slot 14. The four card slots are arranged at intervals, and the four card slots are all long strip structures with the same width and depth.

[0031] Among them, a panel cavity 15 for installing the display panel assembly 2 is opened on the front side surface of the display housing 1 at the middle position of the four card slots, and second grooves 151 are opened on the opposite sides of the panel cavity 15, wherein the second grooves 151 are vertical structures and are respectively located on the side walls and bottom surface of the panel cavity 15, and the number of second grooves 151 is multiple, and the second grooves 151 on both sides are respectively on the same side and close to the first card slot 11 and the third card slot 13, and the bottom surface of the second groove 151 is lower than the bottom surface of the panel cavity 15, and the side surface is recessed towards the side surface of the panel cavity 15, so it will not affect the installation of the display panel assembly 2.

[0032] Furthermore, the bottom of the first card slot 11 and the third card slot 13 are each provided with a plurality of conductive sheets 4 extending to the bottom of the display panel assembly 2, and the conductive sheets 4 are electrically connected to the bottom end of the display panel assembly 2. The bottom surfaces of the first card slot 11 and the third card slot 13 are each provided with a first groove 112 connected to the second groove 151, and the number of the first grooves 112 in the first card slot 11 and the third card slot 13 is the same as the number of the second grooves 151. The first groove 112 and the second groove 151 form a cavity consistent with the shape of the conductive sheet 4 for placing the conductive sheet 4, thereby achieving electrical connection between the conductive sheet 4 and the display panel assembly 2, so that the static electricity generated by the display panel assembly 2 is initially diverted by the conductive sheet 4.

[0033] Furthermore, a connecting port 3 is opened between each two adjacent card slots, and the interior of the connecting port 3 is filled with a conductive block 31. The two ends of the conductive block 31 respectively extend into two different card slots. The conductive block 31 can electrically connect the internal structures of the two adjacent card slots, so that the structures inside the four card slots can achieve the effect of electrostatic transmission.

[0034] Furthermore, an installation opening 8 is provided at one end of the first card slot 11, the second card slot 12 and the fourth card slot 14, and a sealing block 81 is installed inside the installation opening 8 by means of a small bolt. A card slot 132 is provided in the middle of the third card slot 13, and a sealing block 81 is also installed inside the card slot 132. When the seal is installed in the card slot, it can be connected by vertical pressing or horizontally sliding along the notch at one end of the card slot. After the seal is installed in the card slot, the sealing block 81 is installed at one end of the card slot to achieve sealing of the card slot.

[0035] Furthermore, the four seals have the same structure and all include a positioning layer 9, the bottom and side of the positioning layer 9 are respectively provided with conductors electrically connected to the conductive sheet 4 and the conductive block 31, and the top of the positioning layer 9 is provided with an isolation layer 91, the isolation layer 91 includes a thin film integrated circuit layer fixedly attached to the top of the positioning layer 9, the thin film integrated circuit is electrically connected to the conductors at the bottom and side of the positioning layer 9, and the static electricity generated by the display panel assembly 2 is transferred to the thin film integrated circuit layer through the conductive sheet 4 and the conductors in the positioning layer 9;

[0036] Among them, the positioning layer 9 also includes a conductive hydrogel layer attached to the top of the thin film integrated circuit layer, and an anti-wear rubber layer is attached to the top of the conductive hydrogel layer. The anti-wear rubber layer is insulated and exposed on the outer surface of the display screen housing 1. The anti-wear rubber layer and the hydrogel layer are adhered to each other, and the anti-wear rubber layer can be torn off for easy replacement. The thin film integrated circuit layer, the conductive hydrogel layer and the anti-wear rubber layer are consistent in shape and attached up and down. When the static electricity transmitted to the thin film integrated circuit layer continues to be transmitted to the conductive hydrogel layer, since there are a large number of water molecules in the hydrogel, when the static electricity approaches and contacts, due to the conductivity of water, the charge can be transmitted and neutralized through the water, thereby achieving the effect of eliminating static electricity. The anti-wear rubber layer attached to the outside of the conductive hydrogel layer can completely block the charge, so that when the user uses the flat panel display, there will be no static interference.

[0037] Furthermore, the inner wall of each card slot is provided with a first baffle 5, a second baffle 6 and a third baffle 7, all of which are made of rubber and have certain elasticity and deformation ability. The second baffle 6 and the third baffle 7 are on the same side and are arranged opposite to the first baffle 5. The two sides of the positioning layer 9 are respectively provided with a first reinforcement strip 92, a second reinforcement strip 93 and a third reinforcement strip 94, all of which are also made of rubber. The second baffle 6 and the third baffle 7 are on the same side as the first reinforcement strip 92 and the second reinforcement strip 93 and are in contact with each other up and down. The first baffle 5 and the third reinforcement strip 94 are on the same side and are in contact with each other up and down, which can improve the connection strength between the seal and the card slot and ensure the normal function and stability of the equipment during use.

[0038] When the above embodiment is working, the four seals are respectively installed in the corresponding card slots, and the second baffle 6 and the third baffle 7 are on the same side as the first reinforcement strip 92 and the second reinforcement strip 93 and are in contact with each other up and down, and the first baffle 5 and the third reinforcement strip 94 are on the same side and are in contact with each other up and down, which can improve the connection strength between the seal and the card slot. After installation, the sealing block 81 is installed at one end of the card slot to achieve the blocking of the card slot. The static electricity generated by the display panel assembly 2 is transmitted to the thin film integrated circuit layer through the conductive sheet 4 and the conductor in the positioning layer 9. The static electricity of the thin film integrated circuit layer continues to be transmitted to the conductive hydrogel layer. Since there are a large number of water molecules in the hydrogel, when static electricity approaches and contacts, due to the conductivity of water, the charge can be transmitted and neutralized through the water, thereby achieving the effect of eliminating static electricity. The anti-wear rubber layer attached to the outside of the conductive hydrogel layer can completely block the charge, thereby improving the user experience.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
