Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display panel, and more particularly to a liquid crystal display panel which can effectively prevent external electrostatic damage. t [Prior Art] At present, liquid crystal display devices are gradually replacing the traditional cathode ray tube (CRT) display device for computers, and because the liquid crystal display device is light, thin and small, it is very suitable. Used in desktop computers, laptops, personal digital assistants (PDAs), mobile phones, televisions, and a variety of office automation and audiovisual equipment. Generally, a liquid crystal display device includes a liquid crystal display panel for displaying a face and a backlight module for providing the liquid crystal display panel with a light source for display. 1 and FIG. 2, FIG. 1 is an exploded perspective view of a prior art liquid crystal display panel, and FIG. 2 is a schematic view of the liquid crystal display panel 1 shown in FIG. The liquid crystal display panel 10 includes a display area 1〇3, a terminal area 〇1 adjacent to the display area 103, a driving integrated circuit wafer 114, and a flexible circuit board 116. The drive integrated circuit wafer 114 is disposed on the surface of the terminal region 101. The flexible circuit board 116 is used to connect the driving integrated circuit chip 114 and an external circuit (not shown). The display area 103 includes a plurality of driving lines (not shown) and a ground line 108. The driving line is used to transmit a driving voltage required for display of the liquid crystal display panel 1 , which generally includes a scan driving line and a data driving line. The grounding wire 108 extends to the terminal area 1〇1 for absorbing the electricity generated by the external environment. ^Sub-area 1CU includes a plurality of terminals U1 and a plurality of connection terminals 1 Mountain 12. The plurality of terminals m are formed by extending the drive line of the display area (10) to the terminal area 101. The plurality of connection terminals 112 respectively correspond to the plurality of terminals 111 and are not connected to each other. The driver integrated circuit chip 4 is electrically connected to the plurality of terminals U1 and the number of terminals + 112, respectively. The flexible circuit board 116 is electrically connected to the driving integrated circuit wafer 114 via the complex connection terminal 112. The display signal generated by the external circuit is transmitted to the driving integrated circuit chip 114 by the flexible circuit board ι 6 , and the display signal is processed by the driving integrated circuit chip 114 to be converted into a corresponding driving voltage, and The plurality of terminals 111 are transmitted to the drive line. However, although the grounding wire 108 can absorb a part of the static electricity, there is still a large amount of static electricity generated by the terminal 111 and the grounding wire 108 being exposed to the external environment and entering the liquid crystal display panel 10 at the moment. The exposed terminal U1 of the exposed light enters the display area 103 and the driving integrated circuit chip 114, destroying the driving line, or causing the driving integrated circuit wafer 114 to generate an abnormal operation, thereby destroying the driving integrated body. The circuit chip U4, therefore, the liquid crystal display panel 1 has a low electrostatic protection capability. In order to solve the above problems, the industry proposes another electrostatic protection measure, that is, an electrostatic discharge protection unit is arranged for each drive line, and the lead end is electrically connected to the ground line via the electrostatic discharge protection unit, when static electricity enters from the outside. At the time of the terminal, it is first absorbed by the ESD protection unit to the ground line, thereby reducing the static electricity entering the driving line and driving the integrated circuit chip, and improving the electrostatic protection capability of the liquid crystal display panel to some extent. 200947028

FIG. 3 is an exploded perspective view of the first embodiment of the liquid crystal display panel of the present invention, and FIG. 4 is a schematic view showing the assembled liquid crystal display panel 20 of FIG. The liquid crystal display panel 20 includes a terminal region 201, a display region 203 adjacent to the terminal region 201, a driving integrated circuit wafer 214, a flexible circuit board 216, and an anisotropic conductive film (ACF). 218. The driver integrated circuit wafer 214 and the flexible circuit board 216 are fixed to the terminal region 201 by the anisotropic conductive film 218. The display area 203 includes a plurality of scan drive lines 230, a plurality of data drive lines 232, and a plurality of thin film transistors 234. The plurality of scan driving lines 230 are arranged in parallel with each other. The data driving lines 232 are respectively arranged perpendicular to the scanning driving lines 230. The minimum area enclosed by the scanning driving lines 230 and the data driving lines 232 defines a pixel area ( Not marked). The thin film β transistor 234 is located in each pixel region. The scan drive line 230 transmits a scan voltage to the thin film transistor 234 to control its turn on or off. The data drive line 232 transmits the desired data voltage to the thin film transistor 234 to achieve a facet display of the pixel area in which the thin film transistor 234 is located. The terminal area 201 includes a plurality of terminals 211 and a plurality of connection terminals 212. The plurality of terminals 211 are formed by extending the scan driving line 230 and the data driving line 232 of the display area 203 to the terminal area 201, respectively. The plurality of connection terminals 212 are respectively provided with conductive pattern layers of opposite connection ends (not shown), which respectively correspond to the plurality of extraction terminals 211. The anisotropic conductive film 218 200947028 is a thermosetting or thermoplastic resin film containing conductive particles (not shown) having a shape corresponding to the terminal region 201. The driving integrated circuit chip 214 includes a plurality of input pins (not shown) and a plurality of output pins (not shown), which are respectively pressed in the direction perpendicular to the terminal region 201 by the anisotropic conductive film 218 to The plurality of connection terminals 212 and the plurality of terminals 211 are electrically connected to the corresponding one of the connection terminals 212 by the conductive particles vertically connected by the extrusion in the anisotropic conductive film 218. The plurality of conductive particles vertically connected in the anisotropic conductive film 218 are electrically connected to the corresponding one of the terminals 211. Referring to FIG. 5 together, a schematic cross-sectional view of the flexible circuit board 216 of the liquid crystal display panel 20 shown in FIG. 3 along the line V-V is shown. The flexible circuit board 216 includes an insulating base film 260, a plurality of conductive lines 262, a plurality of gold fingers 263, a ground line 265, and a protective film 267. The material of the insulating base film 260 is Polythylene Terephthalate (PET), Polyimide (PI), etc., which defines an opening 261, and the opening 261 and the driving integrated circuit Wafers 214 are matched. The plurality of conductive lines 262 and the plurality of gold fingers 263 are disposed on a surface of the insulating base film 260 facing the terminal region 201. The plurality of gold fingers 263 are respectively formed from the ends of the plurality of conductive lines 262, which are adjacent to the openings 261 and respectively correspond to the plurality of connection terminals 212. The protective film 267 is an insulating film covering the plurality of conductive traces 262 to sandwich the conductive traces 262 from the insulating base film 260 and expose the plurality of gold fingers 263 to the outside. The grounding wire 265 is disposed on the surface of the insulating base film 260 facing away from the terminal region 201, and is disposed along the edge of the surface of the insulating base film 260. The flexible circuit board 216 is pressed into the terminal area 201 in the direction perpendicular to the terminal area 201 by the anisotropic conductive film 218, so that it completely covers the terminal end 211 and the connection terminal 212 of the terminal area 201. The insulating base film 260 of the flexible circuit board 216 is insulated from the external environment. The driving integrated circuit chip 214 passes through the opening 261. The plurality of gold fingers 263 are electrically connected to the plurality of connecting terminals 212 by the conductive particles in the anisotropic conductive film, so that the display signal generated by the external circuit is generated. The display circuit is processed by the driving integrated circuit chip 214 to be converted into a corresponding driving voltage by the conductive circuit 262 of the flexible circuit board 216 and transmitted to the driving integrated circuit chip 214 via the connecting terminal 212. The plurality of terminals 211 are transmitted to the scan driving line 230 and the data driving line 232 to realize the display of the display area 203. Compared with the prior art, the liquid crystal display panel 20 of the present invention covers the terminal region 201 of the flexible circuit board 216, and the insulating base film 260 of the flexible circuit board 216@ causes the terminal 211 of the terminal region 201 and the connection. The terminal 212 is insulated from the external environment, so that the external static electricity cannot penetrate the lead-out end 211 and the connecting terminal 212 through the insulating base film 260 of the flexible circuit board 216, that is, the external static electricity is cut into the lead-out end 211 and the connecting terminal 212. The path prevents the external static electricity from entering the driving integrated circuit chip 214 and the driving line of the display area 203 via the terminal 211 and the connecting terminal 212, thereby improving the anti-static interference capability of the liquid crystal display panel 20. In addition, only the grounding wire 265 is exposed on the surface of the insulating base film 260, and external static electricity can be gradually released by the grounding wire 265 to prevent external static electricity from being deposited on the surface of the flexible circuit board 216 to the liquid crystal display panel 20 Other components around it cause damage or damage to the operator, improving their operational safety. Referring to FIG. 6, the second embodiment of the liquid crystal display panel of the present invention is not intended to be the same as the liquid crystal display panel 30. The main difference is that the flexible circuit board 316 has a conductive line ( The driving circuit chip 314 is directly formed on the flexible circuit board 316, and the input pin and the output pin thereof are respectively associated with the conductive line and the flexible circuit board 316. The gold finger 363 is electrically connected. The liquid crystal display panel 30 does not include a connection terminal, and the gold finger 363 is directly and electrically connected to the terminal 311. The display signal enters the driving integrated circuit wafer 316 via the conductive line, and is processed and outputted to the driving line of the display area by the gold finger 363 and the leading end 311. The liquid crystal display panel 30 directly forms the driving integrated circuit wafer 314 on the flexible circuit board 316, thereby eliminating the need to directly press the driving circuit collective wafer 314 to the terminal region, thereby reducing the possibility that the pressing process may cause damage to the terminal region. The probability of a certain degree of increase in its yield. The present invention is not limited to the above embodiments. For example, a surface of the driving integrated circuit wafer 214 and the opening 261 may be coated with a protective adhesive to prevent static electricity from being driven by the integrated circuit wafer 214 and the opening 261. The gap that may exist between them enters the inside and acts as a waterproof seal. The flexible circuit board 216 does not include the opening 261. When the flexible circuit board 216 is pressed into the terminal area 201, it does not press the corresponding portion of the integrated circuit wafer 214. 12 200947028 In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law.
