BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.

[0018] Figure 1 This is a schematic structural diagram of a TFT that is easy to discharge static electricity in one embodiment of the utility model;

[0019] Figure 2 for Figure 1 A schematic diagram of a binding region of a TFT structure that is easy to release electrostatic discharge; DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1 and Figure 2A TFT structure that is easy to release static electricity includes: a TFT body 10 and an electrostatic guide line 20. A binding area 100 is opened on one side of the TFT body 10. An FPC binding position 110 is set on the binding area 100. A pin piece 111 is set on the FPC binding position 110. The pin piece 111 includes a plurality of long pins 111a. The long pins 111a are connected to the electrostatic guide line 20. A first conductive position 120 and a second conductive position 130 are respectively set at both ends of the binding area 100. The first conductive position 120 and the second conductive position 130 are relatively parallel.

[0022] It should be noted that before TFT10 is bound to the IC chip and the FPC, the long pin 111a on the pin sheet 111 is connected to the electrostatic guide line 20 to release the static electricity in TFT10, so that no charge remains in TFT10, thereby improving the ESD performance of the TFT10 product and ensuring product quality; a first conductive position 120 and a second conductive position 130 are respectively set at both ends of the binding area 100, and silver paste is spot-coated on the first conductive position 120 and the second conductive position 130, so that after TFT10 is attached to the polarizer, the static electricity in the polarizer is released, further ensuring that there is no charge remaining in the TFT10 display module, thereby avoiding problems such as VCOM level being affected, afterimages, flickering, and touch failure.

[0023] Please refer again Figure 2 In one embodiment, the pin sheet 111 further includes a plurality of short pins 111b, and the long pins 111a and the short pins 111b are arranged relatively neatly. Such an arrangement makes the pin sheet 111 compact, thereby facilitating the subsequent connection between the FPC binding position 110 on the TFT 10 and the FPC.

[0024] Please refer again Figure 2 In one embodiment, the long pin 111a includes a VCOM pin, a GND pin and a DUMMY pin. The GND pin and the DUMMY pin are used to separate different signal lines to prevent the conductive process of the electrostatic guide line 20 from being disturbed. At the same time, the GND pin and the VCOM pin can be used as a reference level of the TFT10. When the reference level of the TFT10 is affected, the display becomes abnormal, indicating that there is static electricity in the TFT10.

[0025] Please refer again Figure 2 In one embodiment, the pin sheet 111 further includes positioning pins 111c, which are disposed at both ends of the pin sheet 111. The purpose of providing the positioning pins 111c is to facilitate the machine to grasp and position the TFT 10 when it is bound to the FPC.

[0026] Preferably, the positioning pin 111c is in a "T" shape.

[0027] Please refer again Figure 2 In one embodiment, pin numbers 112 are provided at both ends of the FPC binding position 110, and anti-warping pins 113 are provided between the pin numbers 112 and the positioning pins 111c. The purpose of providing the anti-warping pins 113 is to prevent the edge of the FPC from warping, thereby affecting the function of the FPC.

[0028] Please refer again Figure 2 In one embodiment, a cutting portion 140 is provided on the main body of TFT10, and the cutting portion 140 is provided between the FPC binding position 110 and the electrostatic guide line 20. After the static electricity in TFT10 is discharged, the electrostatic guide line 20 is cut along the edge of TFT10 and separated from the long pin 111a, so that TFT10 can be connected to other components of the display module.

[0029] In one embodiment, the pin width in the pin sheet 111 is 0.06mm-0.07mm, and the spacing between the pins is 0.04mm-0.06mm. When the pin width is less than 0.06mm, the current carrying capacity is reduced. When the pin width is greater than 0.07mm, the current interconnection is poor, thereby affecting the efficiency of static electricity extraction. When the spacing between the pins is less than 0.04mm, the difficulty of pin welding will increase. When the spacing between the pins is greater than 0.06mm, the space occupied by the pins increases, which greatly reduces the compactness of the pin sheet 111.

[0030] A TFT panel includes a TFT structure that is easy to release static electricity. A plurality of TFTs 10 are arranged on the TFT panel. A guide line grounding area is arranged on the TFT panel. The guide line grounding area is arranged at two ends of the TFT panel.

[0031] It should be noted that in order to facilitate the discharge of static electricity in TFT10, when TFT10 is on the TFT panel, the static electricity is conducted to the ground. A guide line grounding area is provided on the TFT panel, and the static electricity guide lines 20 connected to each TFT10 converge here to uniformly conduct the static electricity to the ground, making the TFT panel structure compact.

[0032] 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.
