Please refer to FIG. 3A to FIG. 3D, and refer to FIG. 1 to FIG. 2 together. FIG. 3A to FIG. 3D respectively illustrate schematic diagrams of electrostatic protection circuits according to four embodiments of the present invention. The static electricity protection circuit 140 includes a first electronic component and/or a second electronic component. As shown in FIG. 3A, the static electricity protection circuit 140 of the present embodiment includes a first electronic component and a second electronic component. The first electronic component is exemplified by a first diode D1, and the second electronic component is exemplified by a second diode. D2, the first diode D1 and the second diode D2 are electrically connected to each other in series, wherein the static electricity protection circuit 140 is electrically connected to the first voltage terminal VT1 and the second voltage terminal VT2, the first voltage The terminal VT1 and the second voltage terminal VT2 respectively provide a first voltage and a second voltage, and the first voltage is different from the second voltage. In a preferred embodiment, the first voltage is greater than the second voltage. In this embodiment, the cathode of the first diode D1 is electrically connected to the first voltage terminal VT1, and the anode thereof is electrically connected to the first conductive member 130. The cathode of the second diode D2 is electrically connected to the anode of the first diode, and the anode thereof is electrically connected to the second voltage terminal VT2. Specifically, the first diode D1 is electrically connected to the first conductive member 130 through the contact VT, and the cathode of the second diode D2 is electrically connected to the first conductive member 130 through the contact VT. Since the anode of the first diode D1 is electrically connected to the first conductive member 130, the cathode is electrically connected to the first voltage terminal VT1. Therefore, when the voltage of the first conductive member 130 is less than the first voltage and the first diode When the forward-directed voltage of D1 is summed, that is, when the first conductive member 130 does not have a large amount of static charge, the first diode D1 is not turned on. Moreover, when the voltage of the first conductive member 130 is greater than the difference between the second voltage and the forward voltage of the second diode D2, the second diode D2 is not turned on, and thus the first conductive member 130 is in a floating state. . In contrast, when the first conductive member 130 accumulates a large amount of positive static charge and raises its voltage to be greater than the sum of the first voltage and the forward voltage of the first diode D1, the first diode D1 is turned on. Therefore, the positive static charge can be conducted to the first voltage terminal VT1 through the first diode D1 to prevent the electrostatic discharge from damaging the components in the panel 100. Therefore, the sum of the first voltage and the forward conduction voltage of the first diode D1 can be designed to be slightly smaller than the electrostatic discharge voltage that the panel 100 can withstand to release the static charge before the panel 100 is damaged. For example, the first voltage may be from +7 to +15 volts, but not limited thereto. In addition, when the first conductive member 130 accumulates a large amount of negative static charge and causes its voltage to drop to be smaller than the difference between the second voltage and the forward voltage of the second diode D2, the second diode D2 is turned on, The negative static charge can be conducted through the second diode D2 to the second voltage terminal VT2 to prevent electrostatic discharge from damaging components within the panel 100. Therefore, the difference between the second voltage and the forward voltage of the second diode D2 can be designed to be slightly larger than the negative voltage of the electrostatic discharge that the panel 100 can withstand to release the static charge before the panel 100 is damaged. For example, the second voltage may be -7 to -15 volts, but is not limited thereto. It is worth mentioning that when the conductive member is directly electrically connected to the voltage terminal having a fixed voltage, the conductive member has a fixed voltage to shield the components in the panel 100, so the touch panel in the panel 100 It is shielded by the conductive member and cannot effectively sense the touch object. For example, when the touch panel is shielded by the conductive member, 10% to 20% of the sensing amount is decreased, thereby affecting the sensitivity of the touch panel to the touch. However, in the embodiment, since the first conductive member 130 is not electrically discharged, the first diode D1 and the second diode D2 are not turned on, so the first conductive member 130 can be in a floating state. Therefore, the first conductive member 130 does not have a shielding effect on the touch panel. Instead, the first conductive member 130 can improve the coupling capacitance between the touch object and the touch panel to improve the touch sensitivity. In other embodiments, the first voltage can be the highest voltage in panel 100 and the second voltage can be the lowest voltage in panel 100. In addition, in the embodiment, the first diode D1 and the second diode D2 can be fabricated in the active circuit layer 114 in conjunction with the process of the active circuit layer 114. For example, the first diode D1 and the second diode D2 may be a diode, a Zener diode, or other diodes suitable for the active circuit layer 114. , but not limited to this. In addition, the number of the first diodes D1 may be plural, and may be connected to each other in series or in parallel. Similarly, the number of the second diodes D2 may be plural, and may be connected to each other in series or in parallel.

In this embodiment, since the static charge entering the panel 100 via the protective plate 160 can be conducted to the static electricity protection circuit 140 through the conductive path of the first conductive member 130, the first diode D1 can be turned on or the second The conduction of the diode D2 conducts a large amount of positive static charge and negative static charge away from the first plate body 110. Therefore, by the electrostatic protection circuit 140 of the embodiment, the electrostatic protection function of the two types of electrostatic charges can be further performed. . In a variant embodiment, the static electricity protection circuit 140 may further include a first resistor R1 and a second resistor R2, wherein the first resistor R1 is connected between the first voltage terminal VT1 and the first conductive member 130, and the second resistor R2 is electrically connected. The first resistor R1 and the second resistor R2 are high-resistance resistors, and the first resistor R1 and the first resistor are connected to the second resistor VT2 and the first conductive member 130 (as shown in FIG. 3B). The connection of the two resistors R2 enables the first conductive member 130 to perform the function of electrostatically protecting the two types of static charges while being in a non-floating state. In another variant embodiment, the static electricity protection circuit 140 may include only the first diode D1 or the second diode D2 (as shown in FIGS. 3C and 3D), such that the panel 100 of the modified embodiment may be selected. The function of electrostatic protection of positive or negative static charge.

It can be seen from the above that when the external static charge enters the panel 100, the static charge can be transmitted to the static electricity protection circuit 140 through the conductive path of the first conductive member 130 to perform the function of electrostatic protection, thereby reducing the panel 100. The negative impact of external static charge on the panel 100 during operation, thereby achieving the effect of protecting the structure and operation of the panel 100.
