[0047] The structural principle and working principle of the present application will be described in detail below in combination with the drawings:

[0048] Figure 1 is an unfolded structure diagram of a display panel according to an embodiment of the present application, Figure 2 is a folded structure diagram of the display panel shown in Figure 1 . As shown in Figures 1-2 , the display panel 100 of the present application comprises a first panel 101, a second panel 103, and a first flexible circuit board 106, the first panel 101 and the second panel 103 are oppositely arranged, the first flexible circuit board 106 is arranged between the first panel 101 and the second panel 103, and the first panel 101 and the second panel 103 are electrically connected through the first flexible circuit board 106.

[0049] As shown in Figure 1 , the first panel 101 has a display area AA and a peripheral area BA arranged adjacently, the peripheral area BA surrounds the display area AA, the peripheral area BA is provided with a first circuit unit 102, the first circuit unit 102 can be arranged in the peripheral area BA below the display area AA, the first circuit unit 102 for example comprises a multiplexer circuit (MUX) and a lead, and can also include other circuit units, and the present application is not limited thereto.

[0050] In an embodiment, the display panel 100 further comprises a gate drive circuit (such as a GOA circuit), the first circuit unit 102 (such as part of the lead) can be electrically connected with the gate drive circuit to transmit at least one driving signal. The gate drive circuit can be arranged in the peripheral area BA, for example, arranged in Figure 1The gate driving circuit can also be disposed in the peripheral area BA on the left and / or right sides of the central display area AA. The display area AA has multiple data signal lines (not shown in the figure) and multiple gate signal lines (not shown in the figure). The multiple data signal lines extend along a first direction, and the multiple gate signal lines extend along a second direction. The first direction and the second direction intersect, for example, perpendicular to each other. The multiple data signal lines are electrically connected to the first circuit unit 102 (such as a multiplexer circuit), and the multiple gate signal lines are electrically connected to the gate driving circuit. The gate driving circuit is electrically connected to a portion of the leads in the first circuit unit 102. In another embodiment, the display area AA also has multiple touch signal lines (not shown in the figure). The multiple touch signal lines can extend along the first direction and be electrically connected to another portion of the leads in the first circuit unit 102. The first circuit unit 102 can be formed of multiple conductive metal layers. The aforementioned multiplexer circuit, leads, etc., can be conductive metal layers of different layers to transmit different signals.

[0051] The second panel 103 is arranged back-to-back with the first panel 101. The second panel 103 has an electrically connected control unit 111 and a second circuit unit 105. The first circuit unit 102 and the second circuit unit 105 are electrically connected via a first flexible circuit board 106, thereby electrically connecting the first panel 101 and the second panel 103. In this invention, the second panel 103 can accommodate some of the circuitry located below the display area in the prior art. Simultaneously, the first flexible circuit board 106 is used to bend the second panel 103 behind the display panel 100, allowing the display panel 100 to meet the requirements of a narrow bezel.

[0052] The control unit 111 generates multiple signals for the normal operation of the display panel 100. These signals are electrically connected to the second circuit unit 105 via the first signal line group 104 and transmitted to the first circuit unit 102 in the first panel 101 via the first flexible circuit board 106. The first circuit unit 102 is electrically connected to the display area AA (and the gate driving circuit, etc.). The multiple signals generated by the control unit 111 can be data signals or drive signals, etc. The drive signals can include clock signals, touch signals, etc., and this invention is not limited thereto. The data signals provided by the control unit 111 can be sequentially transmitted to the data signal lines in the display area AA via the second circuit unit 105 and the first circuit unit 102 (e.g., a multiplexer circuit). The clock signals provided by the control unit 111 can be transmitted to the gate driving circuit via the second circuit unit 105 and the first circuit unit 102 (e.g., some leads) to generate multiple gate driving signals, which are then transmitted to the gate signal lines in the display area AA. The touch signals provided by the control unit 111 can be transmitted to each touch signal line in the display area AA through the second circuit unit 105 and the first circuit unit 102 (e.g., other leads).

[0053] In one embodiment, a test key can also be disposed on the second panel 103. In the manufacturing process, the first panel 101 and the second panel 103 are manufactured on the same mother board. Thus, the test key on the second panel 103 can be used to simulate the electrical measurement or line width monitoring of the relevant film layer on the first panel 101. Alternatively, the identity information (e.g. chip ID) of each display panel 100 can be manufactured on the corresponding second panel 103 to further reduce the wiring / elements on the first panel 101.

[0054] In order to avoid the signals generated by the control unit 111 from being affected by the static electricity caused by the charge accumulation, in the present application, the first electrostatic protection circuit ESD1 is disposed in the second circuit unit 105. The signals generated by the control unit 111 are respectively electrically connected to the first electrostatic protection circuit ESD1 through the first signal line group 104, and then transmitted to the first circuit unit 102 through the first flexible circuit board 106. Thus, the signals generated by the control unit 111 can be effectively protected by the first electrostatic protection circuit ESD1, and the display area AA, the gate drive circuit, and the circuit of the first circuit unit 102 in the first panel 101 can be prevented from being affected by the static electricity and being damaged (e.g. being burned by the large current / large voltage). In addition, in the present application, the first electrostatic protection circuit ESD1 is disposed on the second panel 103, which can provide sufficient space for the disposition of the first electrostatic protection circuit ESD1. In one embodiment, all the signals of the control unit 111 can be connected to the first electrostatic protection circuit ESD1 and protected by the first electrostatic protection circuit ESD1, and the occupied area of the circuit in the peripheral area BA of the first panel 101 can be reduced to meet the requirement of narrow frame.

[0055] In the present embodiment, the first electrostatic protection circuit ESD1 corresponding to the gate drive circuit (e.g. GOA circuit) and the signal lines (e.g. data signal lines) in the display area AA is disposed on the second panel 103. Thus, the signals generated by the control unit 111 can be transmitted to the first circuit unit 102 on the first panel 101 through the first electrostatic protection circuit ESD1 on the second panel 103, and then transmitted to the gate drive circuit and the signal lines in the display area AA by the first circuit unit 102. Not only the lines of the gate drive circuit can be protected, but also the first circuit unit 102 and the signal lines in the display area AA can be protected. In another embodiment, the corresponding electrostatic protection circuit can be disposed according to the circuit to be protected, which is not limited thereto.

[0056] In one embodiment, the electrostatic protection circuit can include a plurality of switch units, a first input terminal and a second input terminal, the plurality of switch units are connected to each signal line in the signal line group one by one, each switch unit includes a first switch module (e.g. TFT switch) and a second switch module (e.g. TFT switch), the first switch module has a first control terminal, a first terminal and a second terminal, the first control terminal is connected to the first terminal, and the second terminal is connected to the corresponding signal line; the second switch module has a second control terminal, a third terminal and a fourth terminal, the second control terminal is connected to the third terminal and connected to the second terminal of the first switch module; the first input terminal is connected to the first terminal of the first switch module, and the second input terminal is connected to the fourth terminal of the second switch module; the first input terminal receives a first voltage signal, and the second input terminal receives a second voltage signal, the first voltage signal is smaller than the second voltage signal; when the corresponding connected signal line has a positive voltage exceeding a first preset value, the second switch module is opened, and the positive voltage is discharged from the second input terminal; when the corresponding connected signal line has a first negative voltage smaller than a second preset value, the first switch module is opened, and the negative voltage is discharged from the first input terminal. The architecture of the electrostatic protection circuit is not limited thereto.

[0057] Figures 3-6 is a schematic diagram of the unfolded structure of the display panel of another embodiment of the present application.

[0058] Figure 1 In the embodiment shown, the first electrostatic protection circuit ESD1 is arranged in the second circuit unit 105, and the first electrostatic protection circuit ESD1 is electrically connected to a plurality of signals generated by the control unit 111. The arrangement of the electrostatic protection circuit in the display panel 100 is not limited thereto. In another embodiment, as shown in Figure 3As shown, a second electrostatic protection circuit ESD2 is further arranged in the first circuit unit 102 of the first panel 101, the first circuit unit 102 outputs a second signal line group 107, the second electrostatic protection circuit ESD2 is electrically connected to the second signal line group 107 via, for example, partial lead lines in the first circuit unit 102, the second signal line group 107 includes a driving signal line electrically connected to the gate driving circuit, the driving signal line, for example, transmits a clock signal or the like to the gate driving circuit. After partial signals generated by the control unit 111 are transmitted to the second electrostatic protection circuit ESD2, the second electrostatic protection circuit ESD2 transmits the signals to the gate driving circuit via the second signal line group 107, so that the second electrostatic protection circuit ESD2 can protect the gate driving circuit. The second electrostatic protection circuit ESD2 is closer to the gate driving circuit, and the protection effect is better. At this time, the first electrostatic protection circuit ESD1 can be electrically connected only to other circuits (such as data signal lines and / or touch signal lines in the display area AA) except the gate driving circuit to protect them, thus, by cooperation of the first electrostatic protection circuit ESD1 on the second panel 103 and the second electrostatic protection circuit ESD2 on the first panel 101, protection of each circuit structure on the first panel 101 is realized, and since the first panel 101 is provided only with the electrostatic protection circuit corresponding to the gate driving circuit, the occupied space is small, which meets the narrow frame requirement.

[0059] At present, the display panel also has a touch function, so that the touch switch circuit is arranged on the display panel. The touch switch circuit is generally arranged in the peripheral area on the opposite side of the display area with the control unit, for example, the control unit is arranged on the lower side of the display area, and the touch switch circuit is arranged on the upper side of the display area, and the driving signal / control signal output by the control unit can be transmitted to the touch switch circuit via the signal lines arranged on the left and right sides of the display area. Figure 4 In the embodiment shown, the display panel 100 is further provided with a touch switch circuit 108, which is different from the prior art, and is arranged on the second panel 103 instead of being arranged on the upper side of the display area AA of the first panel 101. The touch switch circuit 108 can be arranged in the second circuit unit 105, or can be separately arranged in other areas on the second panel 103, which is not limited in the present application. Since the peripheral area BA on the first panel 101 no longer needs to be provided with the touch switch circuit, the frame width of the display panel 100 can be reduced.

[0060] In an embodiment, the touch switch circuit 108 is located between the control unit 111 and the first ESD protection circuit ESD1, which can be formed by the first metal layer (M1), the second metal layer (M2), and the third metal layer (M3). The display panel 100 further comprises a third signal line group 109, both ends of which are electrically connected to the touch switch circuit 108 and the first ESD protection circuit ESD1, respectively. After the touch signal generated by the control unit 111 is transmitted to the touch switch circuit 108, the touch switch circuit 108 outputs the touch signal via, for example, the third metal layer (M3), and transmits the touch signal to the first ESD protection circuit ESD1 through the third signal line group 109, and then to the plurality of touch signal lines in the display area AA. At the same time, the non-touch signal (such as a data signal, a clock signal, etc.) generated by the control unit 111 can be transmitted to the first ESD protection circuit ESD1, the first flexible circuit board 106, and then to the gate drive circuit, the data signal line in the display area AA, etc. after insulatingly passing through the touch switch circuit 108 (via the first metal layer and / or the second metal layer which are insulated from the touch switch circuit 108) or bypassing the touch switch circuit 108. Thus, while the touch switch circuit 108 is arranged on the second panel 103 to reduce the frame width of the first panel 101, the related circuits on the second panel 103 and the first panel 101 can be protected from static electricity by the first ESD protection circuit ESD1 on the second panel 103.

[0061] In an embodiment, the first panel 101 needs to be tested before being bonded with the second panel 103, the first flexible circuit board 106, etc. Figure 5 In the illustrated embodiment, the display panel 100 further comprises a test switch circuit 110, which can comprise a test circuit and a connection pad connected thereto. The test switch circuit 110 is arranged on the first panel 101 and between the first flexible circuit board 106 and the second ESD protection circuit ESD2, and can be electrically connected to the display area AA via the first circuit unit 102. An external test signal can be transmitted to the display area AA via the connection pad and the test switch circuit 110 to test the display area AA. After the test is completed, the connection between the test switch circuit 110 and the display area AA can be cut off; or, during normal display, the test switch circuit 110 is controlled to output no unnecessary electrical signal. It should be noted that, Figure 5 For example only, the position of the test switch circuit 110 is not limited thereto.

[0062] As Figure 1 illustrated, the control unit 111 can be a driving chip (IC), and a plurality of connection pads (pads) can be arranged on the second panel 103 for bonding the driving chip. For example, Figure 1 ,Figure 6 As shown, Figure 1 Different from the embodiment shown, Figure 6 In the embodiment shown, the control unit 111 of the display panel 100 is not directly bound to the second panel 103, but is disposed on the second flexible circuit board 112, which is bound to the second panel 103 and electrically connected to the second signal line group 107, so that the control unit 111 is electrically connected to the first signal line group 104.

[0063] In the present application, the thickness of the second panel 103 is not greater than one half of the thickness of the first panel 101. The first panel 101, for example, includes a thin film transistor (TFT) array substrate and a color film (CF) substrate, and the array substrate and the color film substrate are oppositely disposed. In an embodiment, the array substrate, the color film substrate, and the second panel are made of the same material, for example, a glass substrate, at which time the control unit 111 can be directly bound to the second panel 103, and the present application is not limited thereto. In another embodiment, the array substrate, the color film substrate, and the second panel can be made of different materials, for example, the array substrate and the color film substrate are made of a glass substrate, and the second panel 103 is made of a PCB board, at which time the control unit 111 can be bound to the second panel 103 through the second flexible circuit board 112, and the control unit 111 and the second flexible circuit board 112 can be a COF (chip on Film, chip on film).

[0065] It should be noted that, Figure 1 、 Figures 3-6 The circuit arrangement mode in the embodiment shown is not unique, and can be combined and arranged as needed, and the present application is not limited thereto.
