[0042] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0043] As described in the background art, as shown in Figure 8 In order to improve the anti-static ability of PMOLED, the ITO wire 1-2 of ESD is usually led out at the "T" type alignment mark 1-1 at both ends of the glass binding position, and the shape is a circle around the glass periphery. The anti-static ITO wire is led out from the short side of the alignment mark 1-1, and after winding around the glass periphery, it is connected to the short side of the alignment mark at the other end. This connection method has the risk of ESD striking the adjacent binding position pin under the action of high strength and frequency static electricity.

[0044] In order to solve this technical problem, the present application provides an ESD static line optimization structure of liquid crystal screen, which is applied to the ESD static line.

[0045] Specifically, please refer to Figures 1-8 The ESD static line optimization structure of the liquid crystal screen specifically comprises:

[0046] ESD line body 1, which is arranged between the polarizing plate 11 and the glass substrate 12;

[0047] FPC pin 2, which further extends T-shaped corner 21 on both sides, and the T-shaped corner 21 has lead pin 210;

[0048] One end of the ESD line body 1 is connected to the surface of the lead pin 210 on one side of the T-shaped corner 21, and the other end is wired along the edge of the glass substrate 12 and connected to the other T-shaped corner 21;

[0049] Among them, the ESD line body 1 is combined to form an electrostatic protection area 13 for electrostatic protection of the control line 14 and IC 15 inside.

[0050] The utility model provides an optimized structure of the ESD electrostatic line of the LCD screen, which leads out the two ends of the ESD line body 1 through the ends of the lead-out pins 210, thereby increasing the distance between the lead-out end of the ESD line body 1 and the FPC pin 2, thereby reducing the situation where ESD damages the adjacent binding position pins.

[0051] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0052] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0054] Example 1

[0055] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, an optimized structure of an ESD electrostatic line of a liquid crystal display includes: an ESD line body 1, which is arranged between a polarizer 11 and a glass substrate 12;

[0056] The FPC pin 2 has T-shaped corners 21 extending from both sides thereof, and the T-shaped corners 21 have lead pins 210;

[0057] One end of the ESD line 1 is connected to the surface of the lead-out pin 210 on one side of the T-shaped corner 21, and the other end is routed along the edge of the glass substrate 12 and connected to another T-shaped corner 21, wherein the ESD line 1 encloses an electrostatic protection area 13 for electrostatic protection of the control circuit 14 and IC15 therein.

[0058] The IC15 is arranged below the control circuit 14, and the IC15, FPC pin 2 and control circuit 14 are all arranged on the glass substrate 12. Figure 3 As shown, the left side of the T-shaped angle 21 has a lead pin 210;

[0059] The ESD line 1 includes a U-shaped enclosed section 16 and a lead-out section 17;

[0060] The two lead-out sections 17 are respectively arranged on two sides of the FPC pin 2 and connected with the end of the corresponding U-shaped enclosing section 16. Specifically, the lead-out section 17 is connected with the lead-out pin 210 in the T-shaped corner 21 on the two sides of the FPC pin 2. In the process of electrostatic protection, when the static electricity on the glass substrate 12 is led out towards the direction of the FPC pin 2, the static electricity is led into the FPC pin 2 through the lead-out pin 210. Since the design distance between the lead-out pin 210 and other pins on the FPC pin 2 is increased, compared with the traditional ESD static wire, the ESD injury to the adjacent binding position pin is reduced, and the electrostatic protection effect of the liquid crystal screen is improved.

[0061] The electrostatic lead-out process in the embodiment is as follows: when the strong static electricity impact current impacts on the LCD and enters the control line 14 through the gap of the LCD, the ESD wire body 1 surrounding the periphery of the control line 14 can shield the static electricity, and finally guide the static electricity to the FPC pin 2. The ESD current guided to the FPC pin 2 is grounded and discharged through the static electricity release module on the PCB. The release of the static electricity is completed (the FPC pin 2 is connected with the PCB through the FPC, and the position where the FPC pin is connected on the PCB has a static electricity release grounding wire. The structure principle of the above-mentioned static electricity release is a mature and perfect prior art, and therefore is not further described in the embodiment).

[0062] Embodiment 2

[0063] The ESD static wire optimization structure of the liquid crystal screen provided in embodiment 1 is further optimized. Specifically, as shown in Figure 4 and Figure 8 The U-shaped enclosing section 16 and the control line 14 on the inner side leave a static electricity isolation area 160, and the U-shaped enclosing section 16 and the edge of the glass substrate 12 leave a wiring area 161.

[0064] The width of the static electricity isolation area 160 is greater than the width of the wiring area 161.

[0065] When the ESD wire body 1 is arranged and wired around the glass substrate 12, and in the case where the wiring space is allowed, the wiring around the glass substrate 12 is also as far as possible from the edge of the inner control line, so as to avoid the ESD injury to the adjacent line, and further improve the ESD protection effect of the liquid crystal screen.

[0066] Embodiment 3

[0067] The ESD static wire optimization structure of the liquid crystal screen provided in embodiment 1 or 2 is further optimized. As shown in Figure 5 and Figure 6As shown, the lead-out section 17 has a parallel section 170 and a vertical section 171 , and an angle 172 is formed between the parallel section 170 and the vertical section 171 , wherein the angle 172 in this embodiment is ninety degrees;

[0068] One end of the parallel section 170 is connected to the lead-out pin 210 of the T-shaped angle 21, and the parallel section 170 and the lead-out pin 210 are located on the same straight line. In this way, when the ESD line 1 is conducting static electricity, it is always at the farthest distance from the T-shaped angle 21 before it is introduced into the FPC pin 2. This minimizes the possibility of ESD damaging the adjacent binding pins in the FPC pin 2, so that the static electricity can only be introduced into the lead-out pin 210, thereby ensuring the stability of static electricity conduction.

[0069] One end of the vertical section 171 is connected to the end of the U-shaped enclosed section 16 .

[0070] Example 4

[0071] The ESD electrostatic line optimization structure of the liquid crystal screen provided in Example 3 is further optimized, such as Figure 5 and Figure 6 As shown, the surface of the lead pin 210 is also connected to a shunt line 18, and one end of the shunt line 18 is connected to an electrostatic introduction sawtooth 180;

[0072] Among them, an electrostatic lead-out sawtooth 181 is further provided on one side of the electrostatic lead-in sawtooth 180, and the electrostatic lead-out sawtooth 181 is connected to the ESD line 1, and a gap is left between the electrostatic lead-out sawtooth 181 and the electrostatic lead-in sawtooth 180;

[0073] The ESD line 1 and the shunt line 18 are both ITO lines;

[0074] Through the design of the shunt line 18, when the static electricity is concentrated on the ESD line 1, the static electricity that is to be led toward the FPC pin 2 can be attracted and diverted through the cooperation of the static electricity introduction serrations 180 and the static electricity lead-out serrations 181. In this way, after the concentrated ESD static electricity is diverted, the static electricity will first be introduced into the lead-out pin 210 through the shunt line 18, and the static electricity with it will subsequently be introduced into the lead-out pin 210 through the lead-out section 17, thereby realizing the orderly diversion and lead-out of static electricity, avoiding concentrated release on the lead-out pin 210, and further avoiding the situation where the concentrated static electricity current easily damages the adjacent binding pins in the FPC pin 2.

[0075] The use process of the ESD static wire optimization structure of the liquid crystal screen is as follows: in the case that the wiring space is allowed, the wiring around the glass substrate 12 is as far away from the edge of the internal control route 14 as possible, then the two ends of the ESD wire body 1 are led out through the end of the lead pin 210, the spacing between the leading end of the ESD wire body 1 and the FPC lead pin 2 is increased, in this way, the ESD damage to the adjacent binding position lead pin in the FPC lead pin 2 is reduced by the mode of leading in the static electricity at the end of the lead pin 210, and the ESD static protection effect of the liquid crystal screen is improved;

[0076] Meanwhile, through the design of the shunt wire body 18, when the ESD wire body 1 is concentrated in static electricity, the static electricity can be attracted and shunted through the cooperation of the static electricity leading-in sawtooth 180 and the static electricity leading-out sawtooth 181, the static electricity is input into the FPC lead pin 2 in batches for static electricity leading-out, and the situation that the static electricity current is concentrated and easily damages the adjacent binding position lead pin in the FPC lead pin 2 is further avoided.
