Description of the Invention: [Technical Field] The present invention relates to a flexible circuit board, and more particularly to a flexible circuit board that considers electrostatic discharge protection. [Prior Art] The bonding structure of Chip On Flex (c〇F) is to package the driver integrated circuit on a flexible circuit board in a flip chip manner, and then bond it to the display panel. Therefore, COF can achieve the purpose of downsizing and integrating multi-function chipsets. Figure 1 illustrates a layout of a conventional COF. A flexible stencil 100 has a plurality of driver integrated circuits 110, and each of the driver integrated circuit 110 pins is connected to the pads 101 or 102 via wires printed on the substrate 100 for bonding with the display panel or the printed circuit board. use. The driver integrated circuit 110 is disposed on the flexible substrate 1A by COF technology. The integrated circuit 11A can be electrically connected to the pads 101 and 102 by printing the wires on the substrate 100. There are also some wires on the substrate 100 that are directly electrically connected between the pads 101 and 102 without passing through the integrated circuit 11 . After the COF package is completed, the flexible circuit board 104 can be cut along the cutting line 1〇3. The cut flexible circuit board 104 can be disposed between the display panel and the printed circuit board. Figure 2 is a diagram showing a flexible circuit board 104 connected between the display panel 210 and the printed circuit board 22A. Referring to FIG. 2 and FIG. 2, the soldering pad 1〇1 of the flexible circuit board 104 is lightly connected to the display panel 21〇, and the solder pad 102 of the soft lightning path is coupled to the printed circuit board 220. Therefore, the printed circuit board 220 can transmit the image data and control signals to the drive 1378744 NVT-2006-146 23346 twf.doc/e integrated circuit 110 via the pads 1〇2. The driver integrated circuit 110 can transmit the driving nickname to the display panel 210 via the pad 1〇1. Of course, the printed circuit board 22 can also directly transmit certain signals directly to the display panel 210 via the bonding pads 1〇2 and the pads 1〇1 without passing through the integrated circuit 11(). The conventional flexible circuit board 104 shown in Fig. 1 does not take into account the damage of the static electricity generated on the production line to the integrated circuit 11A on the production line. Therefore, effective electrostatic discharge protection is required to protect the integrated circuit on the flexible circuit board 1〇4. Figure 3 is a solution disclosed in the Patent Publication No. 1228819 of the Republic of China. The flexible circuit board 3〇4 of the substrate 300 is connected to the conductive protection wires 3〇5 through the pads 3〇2 and the wires printed on the substrate 300. With the conductive protection wire 305, the flexible circuit board 3〇4 can guide the static electricity to the production line machine to achieve the electromagnetic static prevention function. After the c〇F package is completed, the flexible circuit board 304 can be cut along the cutting line 303. Since the conductive protection line 305 has been cut, the operation of the flexible circuit board 1〇4 after cutting is not affected by the conductive protection line 305. However, conventional COF flexible boards do not take into account the effects of static electricity on the integrated circuit during assembly. Figure 4 is an illustration of an electrostatic discharge event that occurs with conventional flexible circuit board 400 during assembly. Liquid crystal panels or printed circuit boards often accumulate large amounts of static charge due to poor production environments. After the conventional flexible circuit board 4 is electrically connected between the liquid crystal display panel and the printed circuit board, the static electricity accumulated on the liquid crystal display panel instantaneously flows to the printed circuit board via the wire 401; or the static electricity of the printed circuit board is passed through The wire 401 instantaneously flows to the liquid crystal display panel β. During the process of electrostatic current flowing through the wire 401, the static electricity is coupled to the integrated electrical energy 6 1378744 NVT-2006-146 23346 twf.doc/e Ludouchuan The wire is discharged and damaged. [Invention] The anti-supply method considers the electrostatic discharge board of the electric discharge board, so that the protection object on the flexible circuit board is not damaged by static electricity.

As an example, the inventors of the present invention can make other types of flexible circuit boards according to their needs, which are also within the scope of the present invention. As described above, C〇;p encapsulates the integrated circuit on a flexible substrate in a flip chip manner. For example, the connection line between the liquid crystal display panel and the printed circuit board can be connected using c〇F. Since the driver integrated circuit is configured on a flexible circuit board, the COF can achieve a reduction in printed circuit board size and integration of a multi-function chip set. The COF circuit board may be a two-layer structure in which copper and polyimide are combined. It has excellent heat resistance, high transparency, and flexibility. Figure 5 is a diagram showing an embodiment of a flexible circuit board in consideration of electrostatic discharge protection in accordance with the present invention. The flexible circuit board 500 can be used to be electrically connected between the first substrate and the second substrate. For example, the flexible circuit board 500 can be electrically connected between the liquid crystal display panel and the printed circuit board (PCB), or can be electrically connected between the printed circuit board and the printed circuit board. In the following embodiments, the "first substrate" is implemented by a display panel, and the "second substrate" is realized by a printed circuit board. 8 1378744 NVT-2006-146 23346twf.doc/e In Figure 5, the wires printed on the flexible circuit board $(8) are indicated by only a small number of solid black lines. The flexible circuit board 500 includes a component arrangement region 51A, a first electrical path 520, a second electrical path 53A, and an electrostatic discharge protection conductor. A plurality of first electrical paths connected between the display panel and the printed circuit board are disposed on the substrate of the flexible circuit board 5GG to provide a signal conducting path between the display panel and the printed circuit board. For example, the printed circuit board can be electrically connected to the display panel through the pad 501, the first electrical path 52A, and the pad 5〇2. Further disposed on the substrate of the flexible circuit board 500 is connected between the display panel and the component arrangement area 510, and connected to the component arrangement area 51, a plurality of second electrical paths between the printed circuit boards to provide component configuration. A signal conducting path between the region 510 and the printed circuit board (or display panel). For example, the component placement region 510 can be electrically connected to the display panel through the pad 5〇3, the second electrical path 530, and the pad 504. Component placement area 510 can be used to configure at least one protection object. The subject matter of this protection may be an integrated circuit (such as a driver) or other elements. Here, the integmed circuit (ic) 61 〇 will represent the protection target. Figure 6 is an illustration of an embodiment of the flexible circuit board of Figure 5 configured with at least one guard in accordance with the present invention. Referring to Fig. 5 and Fig. 6, the driver integrated circuit 61 is flip-chip mounted on the component arrangement region 510 and connected to the pads in the component placement region 51A. Therefore, the driver integrated circuit 610 can be connected to the printed circuit board and the display panel through a plurality of second electrical paths disposed on the substrate of the flexible circuit board 5. For example, the driver integrated circuit 61 can be electrically connected to the display panel through the pad 5〇3, the second electrical path 530, and the pad 504. 9 ^^2006-146 23346twf.d〇c/e The protective conductor 540 is disposed between the first electrical path 520 and the second conductive 53G and is insulated from each other. This electrostatic discharge protection is a conductive material other than steel crucibles. The electrostatic discharge protection (5) eMing function prevents the first electric guard 2 from being electrostatically coupled to the second electrical path 530', thereby preventing the internal anti-personal material (such as the integrated circuit (10)) from being damaged by electrostatic discharge. In this embodiment, the ESD protection conductor 54A can be electrically soldered to the inside of the electrical body 510 (this soldering is used to electrically connect to the power supply pin of the product β_). For example, the ESD protection conductor 540 ^ The power source is electrically connected to the driver integrated circuit 61 by the soldering pad 505. Therefore, when the electrostatic discharge is coupled from the first electrical path 52 to the electrostatic discharge preventing conductor 54G, the electrostatic current passes through the driving scum The circuit 610 is internally connected to the printed circuit board by the power rail VDD, or is guided to the printed circuit by the motor VDD, the ESD protection MOSFET, and the power rail GND of the movable body 1 (61). Circuit board. Of course, it is also possible to configure a grounding electrical path (not shown) on the flexible circuit board 500 to pass the static electricity through the electrostatic discharge protection conductor 540, the pad 505, and the ground electrical path (not shown). Guided to the printed circuit board, The electrostatic current is prevented from entering the driver integrated circuit 61. Therefore, the electrostatic discharge protection conductor 54 can reduce the probability of electrostatic discharge coupling to the second electrical path 530. This embodiment does not require changing the "printed circuit board and the flexible circuit board 500". The contact terminal between the two or the "contact terminal between the display panel and the flexible circuit board 500" only needs to change the layout of the flexible circuit board 500. 1378744 NVT-2006-146 23346twf.doc/e Copper St. Figure 6) The electrostatic discharge protection conductor 540 is between the large surface 530, the path 520 and the second electrical path can be used according to its needs. He = the inventor C4n is only the electrostatic discharge protection conductor 117 is a two-example embodiment of the electrostatic discharge prevention according to the present invention. The flexible circuit board 700 of this embodiment implements an electrostatic discharge protection conductor, and disposes the electrostatic discharge iH1174! on the first electrical path 720 and the second electrical path. Compared with the prior embodiment, the present embodiment can be preferably used. The inventors can increase the number of electrostatic discharges according to their needs. For example, it is an implementation example of a flexible circuit board according to the present invention (4) - a test for discharge protection. The flexible circuit board 8 is provided with a first electrostatic discharge protection conductor 840 and a second electrostatic discharge protection conductor 850 between the first electrical path 82A and the second electrical path (4). The first electrical path 820, the second electrical path 830, the first electrostatic discharge protection conductor 84A, and the second electrostatic discharge protection conductor 85A are insulated from each other. The material of the electrostatic discharge protection conductors 840 and 850 may be copper or other conductive material. The ESD protection conductors 840 and 85 can perform a shielding function to avoid the first electrical path 82 and the second electrical path 83〇, thereby preventing the protection target (such as a circuit) from being electrostatically discharged. Damaged. " In this embodiment, the ESD protection conductors 840 and 850 can be electrically connected to different pads in the component arrangement region, and through these solders 11 LJ / Ο NVT-2006-146 23346twfdoc / e padding The protective conductor connected to the integrated circuit 810 can be electrically discharged through the first soldering wire.
