DETAILED DESCRIPTION

[0010] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0011] The term "first" or "second" in the specification and claims of this application may include one or more of the features explicitly or implicitly. In the description of this application, unless otherwise specified, "plurality" means two or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the objects connected before and after are in an "or" relationship.

[0012] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0013] At present, mobile terminal devices are becoming more and more popular, and the application scenarios are becoming more diversified. The requirements for human-computer interaction functions of wearable devices, mobile phones, tablets, computers and other products with integrated display and finger touch functions are getting higher and higher. Therefore, the existing finger touch function can no longer meet the daily application needs in some application scenarios. A common expansion solution in related technologies is to add a set of electromagnetic pen functions to the display touch panel.

[0014] For example, Figure 1 As shown, the related art provides a schematic diagram of the routing of each channel of a display panel that has an electromagnetic pen function on the basis of having a finger touch function. The display panel may include a display area 101, a border area 102, a fan-out area 103 and a binding area 104. The display area (Display Area) of the display panel represents the actual effective display area of ​​the display panel, the border area (Border Area) of the display panel represents the border routing area of ​​the display panel, the fan-out area (Fanout Area) of the display panel represents the fan-out routing area of ​​the display panel, and the binding area (Bonding Area) of the display panel represents the area for binding the display panel and the flexible circuit board (FPC). Among them, the binding area is provided with a gold finger, and the gold finger includes a plurality of arranged conductive contacts, W represents the width of a single conductive contact, P represents the sum of the line width and line spacing of a single conductive contact, and L represents the sum of the line width and line spacing of all conductive contacts on the entire display panel. Among them, X and Y respectively represent the channel routing of the X direction (horizontal) and Y direction (vertical) of the electromagnetic pen function, and RX and TX respectively represent the channel routing of the receiving electrode and the driving electrode of the finger touch function.

[0015] refer to Figure 1 In order to add the electromagnetic pen function to the display panel, it is necessary to add multiple conductive touch pieces at the gold fingers set in the binding area 104 of the display panel to facilitate the transmission of the electromagnetic pen signal, which increases the size of L in the binding area 104 of the touch panel. Due to the limitations of the FPC process and the impedance of the binding area, the size of the binding area is more limited, and the problem of the increase in the size of "L" cannot be met may occur.

[0016] Based on this, the present application provides a display panel. The concept of the present application is to set a target conductive contact in the gold finger on the display panel. The target conductive contact can be connected to the first functional module via the first functional wiring in the first working state, and can be connected to the second functional module via the second functional wiring in the second working state, so that the first functional module and the second functional module can reuse the target conductive contact through the first functional wiring and the second functional wiring respectively. On the premise of adding the gold finger function, the number of conductive contacts required for the gold finger can be reduced, thereby improving the problem of an increase in the number of conductive contacts required for the gold finger due to the increase in the function of the display panel.

[0017] Furthermore, after simultaneously improving and removing the L-size limitation by reducing the number of conductive contacts required for the gold finger, the line width and line spacing of a single conductive contact can be increased, thereby reducing process defects and optimizing the impedance of the binding area.

[0018] For example, Figure 2 As shown, Figure 1 All the conductive contacts of the gold finger of the binding area 104 shown are further subdivided into functional areas ① to ⑥. In the related art, the functional areas are divided into 6 large functional areas from ① to ⑥, ① is the conductive contact connected to the display signal test point (Display Signal Test Point), ② is the conductive contact connected to the channel wiring of the electromagnetic pen X direction (Pen X), ③ is the conductive contact connected to the channel wiring of the touch receiving electrode (Touch RX), ④ is the conductive contact connected to the channel wiring of the touch driving electrode (Touch TX), ⑤ is the conductive contact connected to the channel wiring of the electromagnetic pen Y direction (Pen Y), and ⑥ is the conductive contact connected to the channel wiring of the display signal (Display Signal).

[0019] Among them, Figure 2 The gold fingers of the middle binding area 104 include multiple conductive contacts. In order from left to right, the first ① area may include a+70th to a+50th conductive contacts, the first ② area may include a+50th to a+40th conductive contacts, the first ③ area may include a+40th to a+20th conductive contacts, the first ④ area may include a+20th to a+10th conductive contacts, the first ⑤ area may include a+10th to ath conductive contacts, the ⑥ area may include ath to b+70th conductive contacts, the second ⑤ area may include b+70th to b+60th conductive contacts, the second ④ area may include b+60th to b+50th conductive contacts, the second ③ area may include b+50th to b+30th conductive contacts, the second ② area may include b+30th to b+20th conductive contacts, and the second ① area may include b+20th to bth conductive contacts.

[0020] Among them, Figure 2 In the example, the conductive contact connected to the display signal test point in area ① is used for timing debugging or problem analysis of the display panel, and is not used during normal lighting or touch control of the display panel. Moreover, the number of conductive contacts used for the display signal test point in area ① is generally greater than or equal to the sum of the number of conductive contacts used for the electromagnetic pen X channel in area ② and the number of conductive contacts used for the electromagnetic pen Y channel in area ⑤. Based on this, the embodiment of the present application can reuse the functional area ① with the functional area ②+⑤ on the display panel, saving the number of conductive contacts required for the gold finger.

[0021] For example, Figure 3 As shown, in the embodiment of the present application, the gold fingers of the binding area of ​​the display panel include multiple conductive contacts. In order from left to right, the first ① area (or the first ②+⑤ areas) may include a+50th to a+30th conductive contacts, the first ③ areas may include a+30th to a+10th conductive contacts, the first ④ areas may include a+10th to ath conductive contacts, the ⑥ area may include ath to b+50th conductive contacts, the second ④ areas may include b+50th to b+40th conductive contacts, the second ③ areas may include b+40th to b+20th conductive contacts, and the second ① area (or the second ②+⑤ areas) may include b+20th to bth conductive contacts. It can be seen that in the embodiment of the present application, the conductive contact pieces (②+⑤ areas) required for the electromagnetic pen function can reuse the conductive contact pieces of the display signal test points of the functional area ①. After the conductive contact pieces of the functional area ① are reused to realize the electromagnetic pen function, the number of conductive contact pieces saved can be the number of conductive contact pieces required for the electromagnetic pen function.

[0022] In addition, in addition to the conductive contact pieces required for the electromagnetic pen function described in the previous paragraph, which can reuse the conductive contact pieces of the display signal test points, the embodiments of the present application can also have other application scenarios. For example, the conductive contact pieces required for the touch function can also reuse the conductive contact pieces of the display signal test points, further reducing the number of conductive contact pieces in the gold fingers; for another example, the conductive contact pieces required for the electromagnetic pen function can reuse the conductive contact pieces of the touch function, and on the basis of time-sharing multiplexing of the electromagnetic pen function and the touch function, the number of conductive contact pieces in the gold fingers is further reduced, and so on. The embodiments of the present application do not limit the specific multiplexing scenarios of the conductive contacts in the display panel.

[0023] The display panel and the electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0024] like Figure 4As shown, the embodiment of the present application provides a display panel 100, which may include: a first functional module 110, a second functional module 120, a gold finger 130, a first functional wiring 140 and a second functional wiring 150; the first functional module 110 is connected to the first functional wiring 140, and the second functional module 120 is connected to the second functional wiring 150; The gold finger 130 includes a plurality of conductive contacts 131 ; there is at least one target conductive contact 1311 among the plurality of conductive contacts 131 , and the target conductive contact 1311 is a conductive contact connected to the first functional wiring 140 and the second functional wiring 150 respectively; Among them, the target conductive contact 1311 has a first working state and a second working state. In the first working state, the target conductive contact 1311 is connected to the first functional module 110 via the first functional wiring 140; in the second working state, the target conductive contact 1311 is connected to the second functional module 120 via the second functional wiring 150.

[0025] In the embodiment of the present application, the target conductive contact 1311 refers to a conductive contact connected to two different functional wirings respectively. The conductive contact 131 may include a non-target conductive contact, which is connected to only one functional wiring.

[0026] In an embodiment of the present application, the first functional module 110 and the second functional module 120 can be set in the display area of ​​the display panel 100; the gold finger 130 can be set in the binding area of ​​the display panel 100; the first functional wiring 140 and the second functional wiring 150 can be set in the fan-out area and the border area of ​​the display panel 100.

[0027] In an embodiment of the present application, the first functional module 110 and the second functional module 120 are used to implement different functions. For example, the first functional module 110 can be one of the display signal test functional module, the electromagnetic pen functional module and the touch functional module, and the second functional module 120 can be the other of the display signal test functional module, the electromagnetic pen functional module and the touch functional module.

[0028] In an embodiment of the present application, when the display panel needs to realize more functions, the present application can set a target conductive contact 1311 in the gold finger 130 on the display panel, and the first function wiring 140 and the second function wiring 150 can be connected to the target conductive contact 1311. Since the target conductive contact 1311 can be connected to the first function module 110 via the first function wiring 140 in the first working state, and can be connected to the second function module 120 via the second function wiring 150 in the second working state, the first function module 110 and the second function module 120 reuse the target conductive contact 1311 through the first function wiring 140 and the second function wiring 150 respectively. Under the premise of adding the gold finger function, the number of conductive contacts required for the gold finger 130 can be reduced, thereby improving the problem of an increase in the number of conductive contacts required for the gold finger due to the increase in the function of the display panel.

[0029] According to the display panel provided by the embodiment of the present application, the display panel includes a first functional module 110, a second functional module 120, a gold finger 130, a first functional wiring 140 and a second functional wiring 150; the first functional module 110 is connected to the first functional wiring 140, and the second functional module 120 is connected to the second functional wiring 150; the gold finger 130 includes a plurality of conductive contacts 131; there is at least one target conductive contact 1311 among the plurality of conductive contacts 131, and the target conductive contact 1311 is a conductive contact connected to the first functional wiring 140 and the second functional wiring 150 respectively; wherein the target conductive contact 1311 has a first working state and a second working state, in the first working state, the target conductive contact 1311 is connected to the first functional module 110 via the first functional wiring 140; in the second working state, the target conductive contact 1311 is connected to the second functional module 120 via the second functional wiring 150. In this way, in the scenario where the display panel adds functions, the present application can set a target conductive contact in the gold finger on the display panel, and the first function routing and the second function routing can be connected to the target conductive contact. Since the target conductive contact can be connected to the first function module via the first function routing in the first working state, and can be connected to the second function module via the second function routing in the second working state, the first function module and the second function module can reuse the target conductive contact through the first function routing and the second function routing respectively. On the premise of adding the gold finger function, the number of conductive contacts required for the gold finger can be reduced, thereby improving the problem of an increase in the number of conductive contacts required for the gold finger due to the increase in the function of the display panel.

[0030] In a specific embodiment, Figure 5As shown, in order to realize two working states of the target conductive contact sheet 1311 , the display panel 100 may further include a first switch 160 , and the first switch 160 is disposed between the first functional module 110 and the target conductive contact sheet 1311 .

[0031] Since the target conductive contact sheet 1311 is connected to the first functional module 110 via the first functional wiring 140 , the first switch 160 is disposed between the first functional module 110 and the target conductive contact sheet 1311 , and the first switch 160 may be disposed on the first functional wiring 140 .

[0032] Among them, the embodiment of the present application does not specifically limit the number of first switches 160. The number of first switches 160 can be the same as the number of target conductive contacts 1311. For example, when the target conductive contact 1311 includes one, the first switch 160 can also include one. For another example, when the target conductive contact 1311 includes multiple, the first switch 160 can also include multiple. One first switch 160 is correspondingly arranged between the first functional module 110 and one target conductive contact 1311. The control ends of multiple first switches 160 can be connected to the same control source through the same wire, and then, the unified operation of multiple first switches 160 can be achieved.

[0033] The first switch 160 is a device with a switch function, and the present application does not limit the specific type of the first switch 160 .

[0034] The first switch 160 can be used to control the conduction / interruption of the first functional wiring 140. Further, in the first working state of the target conductive contact 1311, the first functional wiring 140 is turned on by controlling the first switch 160 to be turned on, so that the target conductive contact 1311 is connected to the first functional module 110 via the first functional wiring 140. In addition, in the second working state of the target conductive contact 1311, the first functional wiring 140 can be interrupted by controlling the first switch 160 to be turned off, so that the target conductive contact 1311 can be disconnected from the first functional module 110 via the first functional wiring 140.

[0035] In a specific example, the second functional wiring 150 can remain in a conductive state in the first working state and the second working state of the target conductive contact 1311. In this case, in the second working state of the target conductive contact 1311, the target conductive contact 1311 is conductively connected to the second functional module 120 via the second functional wiring 150.

[0036] Alternatively, in another specific example, the second functional routing 150 can be in an interrupted state in the first working state of the target conductive contact 1311, and remain in a conductive state in the second working state of the target conductive contact 1311. In this case, in the second working state of the target conductive contact 1311, the target conductive contact 1311 is conductively connected to the second functional module 120 via the second functional routing 150.

[0037] It should be pointed out that the embodiment of the present application can switch the working state of the target conductive contact 1311 through the first switch 160, by controlling the first switch 160 to be turned on so that the target conductive contact 1311 enters the first working state, and by controlling the first switch 160 to be turned off so that the target conductive contact 1311 is switched from the first working state to the second working state.

[0038] In this way, the embodiment of the present application can set a first switch 160 between the first functional module 110 and the target conductive contact 1311, and switch the working state of the target conductive contact 1311 by controlling the first switch 160 to switch the target conductive contact 1311 between the first working state and the second working state, thereby realizing time-sharing multiplexing of the target conductive contact 1311.

[0039] In another specific embodiment, in order to avoid the two working states of the target conductive contact piece 1311 from interfering with each other, as shown in FIG. Figure 6 As shown, the display panel may further include a first switch 160 and a second switch 170 , wherein the first switch 160 is disposed between the first functional module 110 and the target conductive contact sheet 1311 , and the second switch 170 is disposed between the second functional module 120 and the target conductive contact sheet 1311 .

[0040] Among them, Figure 5 Compared with the embodiment shown in the figure, the embodiment of the present application adds a second switch 170 to the second functional wiring 150. The conduction / interruption of the second functional wiring 150 is controlled by the second switch 170, so that the target conductive contact 1311 can be switched between the first working state and the second working state. The first switch 160 and the second switch 170 are used together to avoid mutual interference between the two working states of the target conductive contact 1311.

[0041] Among them, since the target conductive contact sheet 1311 is connected to the second functional module 120 via the second functional wiring 150 , the second switch 170 is arranged between the second functional module 120 and the target conductive contact sheet 1311 , and the second switch 170 can be specifically arranged on the second functional wiring 150 .

[0042] Among them, the embodiment of the present application does not specifically limit the number of second switches 170. The number of second switches 170 can be the same as the number of target conductive contacts 1311. For example, when the target conductive contact 1311 includes one, the second switch 170 can also include one. For another example, when the target conductive contact 1311 includes multiple, the second switch 170 can also include multiple. One second switch 170 is correspondingly arranged between the second functional module 120 and one target conductive contact 1311. The control ends of multiple second switches 170 can be connected to the same control source through the same wire, and then, the unified operation of multiple second switches 170 can be achieved.

[0043] The second switch 170 is a device with a switch function, and the present application does not limit the specific type of the second switch 170 .

[0044] The second switch 170 can be used to control the conduction / interruption of the second functional wiring 150. For example, in the first working state of the target conductive contact 1311, by controlling the second switch 170 to be disconnected, the target conductive contact 1311 can be disconnected from the second functional module 120 via the second functional wiring 150; in the second working state of the target conductive contact 1311, by controlling the second switch 170 to be turned on, the target conductive contact 1311 can be turned on from the second functional module 120 via the second functional wiring 150.

[0045] It should be pointed out that in the first working state of the target conductive contact 1311, the second functional wiring 150 can be disconnected by controlling the second switch 170 to be disconnected, thereby avoiding the problem of distortion of the signal transmitted on the first functional wiring 140 caused by excessive load on the second functional wiring 150 and the second functional module 120.

[0046] In this way, the embodiment of the present application can set a first switch 160 between the first functional module 110 and the target conductive contact 1311, and control the first switch 160 to switch the working state of the target conductive contact 1311, so that the target conductive contact 1311 switches between the first working state and the second working state, thereby realizing time-division multiplexing of the target conductive contact 1311. At the same time, a second switch 170 is set between the second functional module 120 and the target conductive contact 1311, and in the first working state of the target conductive contact 1311, the second functional wiring 150 can be disconnected by controlling the second switch 170 to be disconnected, thereby avoiding the problem of distortion of the signal transmitted on the first functional wiring 140 caused by excessive load of the second functional wiring 150 and the second functional module 120.

[0047] In a specific embodiment, reference Figure 6, the working states of the first switch 160 and the second switch 170 can be opposite. For example, when the first switch 160 is turned on, the second switch 170 is turned off; when the first switch 160 is turned off, the second switch 170 is turned on.

[0048] For example, in the first working state of the target conductive contact 1311, the first functional wiring 140 is turned on by controlling the first switch 160 to be turned on, so that the target conductive contact 1311 is connected to the first functional module 110 via the first functional wiring 140. At the same time, the second functional wiring 150 is interrupted by controlling the second switch 170 to be turned off, thereby avoiding the problem of distortion of the signal transmitted on the first functional wiring 140 caused by excessive load on the second functional wiring 150 and the second functional module 120.

[0049] In addition, in the second working state of the target conductive contact 1311, the second functional wiring 150 is turned on by controlling the second switch 170 to be turned on, so that the target conductive contact 1311 is connected to the second functional module 120 via the second functional wiring 150. At the same time, the first functional wiring 140 is interrupted by controlling the first switch 160 to be turned off, thereby avoiding the problem of distortion of the signal transmitted on the second functional wiring 150 caused by excessive load on the first functional wiring 140 and the first functional module 110.

[0050] In this way, in the embodiment of the present application, the working states of the first switch 160 and the second switch 170 are opposite. By using the first switch 160 and the second switch 170 in combination, the target conductive contact 1311 can be flexibly switched between the first working state and the second working state, and mutual interference between the two working states of the target conductive contact 1311 can also be avoided.

[0051] In another specific embodiment, in order to further reduce the number of control signals of the first switch 160 and the second switch 170 and simplify the circuit structure of the display panel, the first switch 160 has a first control end and the second switch 170 has a second control end; the first control end and the second control end can be connected to the same control source (as shown in the figure).

[0052] In the embodiment of the present application, the control source may be a control chip on the display panel, and the control chip may be arranged in the fan-out area.

[0053] Of course, in other embodiments, the control source may also be a microcontroller chip on the mainboard of the electronic device, and the present application does not limit the specific type of the control source.

[0054] Among them, the first control end of the first switch 160 and the second control end of the second switch 170 can be connected to the same control source through the same wire, and then the first switch 160 and the second switch 170 can be synchronously controlled by the same control signal from the same control source, thereby reducing the number of control signals of the first switch 160 and the second switch 170 and simplifying the circuit structure of the display panel.

[0055] For example, in order to realize that the first switch 160 and the second switch 170 are controlled by the same control signal and the working states of the first switch 160 and the second switch 170 are opposite, the switch types of the first switch 160 and the second switch 170 can be different, so that the control principles of the first switch 160 and the second switch 170 are opposite. For example, the control principles of PMOS (P-channel metal oxide semiconductor field effect transistor) and NMOS (N-channel metal oxide semiconductor field effect transistor) are opposite. NMOS is in the on state when the gate receives a high-level signal and is in the off state when receiving a low-level signal; PMOS is in the on state when the gate receives a low-level signal and is in the off state when receiving a high-level signal.

[0056] Based on this, in the embodiment of the present application, the first switch 160 can be set to be one of NMOS and PMOS, and the second switch 170 can be the other of NMOS and PMOS.

[0057] In this way, the present application sets the first switch 160 and the second switch 170 of different control types, so that the first switch 160 and the second switch 170 are controlled by the same control signal and the working states of the first switch 160 and the second switch 170 are opposite.

[0058] Of course, in other embodiments, the present application may also adopt other circuit structures to realize that the first switch 160 and the second switch 170 are controlled by the same control signal, and the working states of the first switch 160 and the second switch 170 are opposite. For example, in other embodiments (not shown in the figure), the first switch 160 and the second switch 170 may be set to be of the same type, the first switch 160 and the second switch 170 are both NMOS, or the first switch 160 and the second switch 170 are both PMOS, the first control end of the first switch 160 is directly connected to the control source, and the second control end of the second switch 170 is connected to the same control source via an inverter. In this way, the first switch 160 and the second switch 170 are set to be of the same type, and an inverter is set at the second control end of the second switch 170, so that the working states of the first switch 160 and the second switch 170 are opposite.

[0059] In addition, in actual applications, the first switch 160 and the second switch 170 share a common mask with a cell test (CT) circuit in a display panel process and are fully compatible in terms of process. There is no additional design and process cost, etc., which can reduce the design cost and manufacturing cost of the first switch 160 and the second switch 170.

[0060] In addition, in actual application scenarios, the first functional module 110 and the second functional module 120 can implement different functions in different time periods. For example, the first functional module 110 can implement the test function of the display panel, and the second functional module 120 can implement the electromagnetic pen function of the display panel. Alternatively, in other embodiments, the present application can also implement the electromagnetic pen function of the display panel by the first functional module 110 and the second functional module 120 implements the test function of the display panel, and the present application does not limit this.

[0061] For another example, the first functional module 110 can implement the test function of the display panel, and the second functional module 120 can implement the finger touch function of the display panel. Alternatively, in other embodiments, the present application can also implement the finger touch function of the display panel by the first functional module 110, and the second functional module 120 implements the test function of the display panel, and the present application does not limit this.

[0062] For another example, the first functional module 110 can implement the electromagnetic pen function of the display panel, and the second functional module 120 can implement the finger touch function of the display panel. Alternatively, in other embodiments, the present application can also implement the finger touch function of the display panel by the first functional module 110, and the second functional module 120 implements the electromagnetic pen function of the display panel, and the present application does not limit this.

[0063] The following describes the various application scenarios mentioned above with specific examples.

[0064] In a specific embodiment, taking the first functional module 110 realizing the test function of the display panel and the second functional module 120 realizing the electromagnetic pen function of the display panel as an example, Figure 7-1 As shown, the first functional module 110 may include a display driving circuit 111, and the first functional wiring 140 may include a display test signal wiring 141; the second functional module 120 may include an electromagnetic pen electrode 121, and the second functional wiring 150 may include an electromagnetic pen signal wiring 151; The display driving circuit 111 may be connected to the target conductive contact sheet 1311 via the display test signal wiring 141 ; and the electromagnetic pen electrode 121 may be connected to the target conductive contact sheet 1311 via the electromagnetic pen signal wiring 151 .

[0065] The display driving circuit can output a display test signal, and the electromagnetic pen electrode can output an electromagnetic pen signal.

[0066] The display test signal may be an output signal (SP_OUT_R) and a start signal (SP_STV_R) of a scan PMOS tube in a display driving circuit. The present application does not limit the number and specific types of display test signals output by the display driving circuit.

[0067] Among them, the electromagnetic pen signal can be two signals (Pen_X1 and Pen_X2) of the electromagnetic pen transverse electrodes, or two signals (Pen_Y1 and Pen_Y2) of the electromagnetic pen longitudinal electrodes, etc. This application does not limit the number and specific types of electromagnetic pen signals output by the electromagnetic pen electrodes.

[0068] The electromagnetic pen electrode may include at least one of an electromagnetic pen transverse electrode and an electromagnetic pen longitudinal electrode. The electromagnetic pen transverse electrode may include at least one, and the electromagnetic pen longitudinal electrode may include at least one. The electromagnetic pen transverse electrode may output an electromagnetic pen transverse electrode signal, and the electromagnetic pen longitudinal electrode may output an electromagnetic pen longitudinal electrode signal.

[0069] For example, Figure 7-1 As shown, the electromagnetic pen electrode 121 may include: an electromagnetic pen transverse electrode 1211 and an electromagnetic pen longitudinal electrode 1212; the electromagnetic pen signal trace 151 includes an electromagnetic pen transverse electrode signal trace and an electromagnetic pen longitudinal electrode signal trace; the number of target conductive contact pads 1311 is N, and the N target conductive contact pads 1311 include a first target conductive contact pad 13111 and a second target conductive contact pad 13112; N is an integer greater than 1; The electromagnetic pen transverse electrode 1211 is connected to the first target conductive contact piece 13111 through the electromagnetic pen transverse electrode signal wiring; the electromagnetic pen longitudinal electrode 1212 is connected to the second target conductive contact piece 13112 through the electromagnetic pen longitudinal electrode signal wiring.

[0070] Figure 7-2 for Figure 7-1 The timing diagram of various signals on the display panel is shown. Figure 7-2In the first working state, the control signal of the first switch 160 is high level, the first switch 160 is turned on, the display driving circuit 111 can output the display test signal normally without additional requirements, and the electromagnetic pen electrode 121 does not receive or send any electromagnetic pen signal (which can be achieved by putting the electromagnetic pen control chip into sleep mode) to avoid interference of the electromagnetic pen signal on the display test signal. In the second working state, the control signal of the first switch 160 is low level, the first switch 160 is turned off, the display driving circuit 111 can output the display test signal normally without additional requirements, but because the first switch 160 is turned off, the display test signal routing 141 is interrupted, and there is no display test signal on the target metal contact sheet (such as the first target metal contact sheet 13111), which will not interfere with the electromagnetic pen signal.

[0071] refer to Figure 7-3 ,and Figure 7-1 Compared with the display panel shown in FIG. 1 , the display panel 100 further includes a second switch 170. Wherein, when the display panel further includes the second switch 170, the working state of the second switch 170 is opposite to that of the first switch 160. For example, the first switch 160 and the second switch 170 may both be NMOS, which is turned on when the switch control signal is at a high level, and is turned off when the switch control signal is at a low level.

[0072] Figure 7-4 for Figure 7-3 The timing diagram of various signals on the display panel is shown in Figure 7-4 In the first working state, the control signal of the first switch 160 is high level, the first switch 160 is turned on, the display driving circuit 111 can output the display test signal normally without additional requirements, and the electromagnetic pen electrode 121 does not receive or send any electromagnetic pen signal (which can be achieved by putting the electromagnetic pen control chip into sleep mode) to avoid the electromagnetic pen signal from interfering with the display test signal. In addition, in the first working state, the control signal of the second switch 170 is low level, the second switch 170 is turned off, and the electromagnetic pen signal wiring 151 is interrupted, which can avoid the risk of distortion of the display test signal caused by the load of the electromagnetic pen signal wiring 151 and the electromagnetic pen electrode 121.

[0073] In the second working state, the control signal of the first switch 160 is at a low level, the first switch 160 is disconnected, and the display driving circuit 111 can output the display test signal normally without additional requirements. However, since the first switch 160 is disconnected, the display test signal wiring 141 is interrupted, and there is no display test signal on the target metal contact piece, which will not interfere with the electromagnetic pen signal. In addition, in the second working state, the control signal of the first switch 160 is at a low level, the first switch 160 is disconnected, and the display test signal wiring 141 is interrupted, which can avoid the risk of distortion of the electromagnetic pen signal caused by the load of the display test signal wiring 141 and the display driving circuit 111.

[0074] In this way, the display driving circuit 111 and the electromagnetic pen electrode 121 reuse the target conductive contact 1311 through the display test signal routing 141 and the electromagnetic pen signal routing 151 respectively. Under the premise of adding the gold finger function, the number of conductive contacts required for the gold finger can be reduced, thereby improving the problem of an increase in the number of conductive contacts required for the gold finger caused by adding the electromagnetic pen function to the display panel.

[0075] In another specific embodiment, taking the first functional module 110 realizing the test function of the display panel and the second functional module 120 realizing the finger touch function of the display panel as an example, Figure 8 As shown, the first functional module 110 includes a display driving circuit 112, and the first functional wiring 140 includes a display test signal wiring 142; the second functional module 120 includes a touch electrode 122, and the second functional wiring 150 includes a touch signal wiring 152; The display driving circuit 112 is connected to the target conductive contact piece (eg, the third target conductive contact piece 13113 ) through the display test signal wiring 152 ; and the touch electrode 122 is connected to the target conductive contact piece through the touch signal wiring 152 .

[0076] The display driving circuit 112 can output a display test signal, and the touch electrode 122 can output a touch signal.

[0077] The display test signal may be an output signal (SP_OUT_R) and a start signal (SP_STV_R) of a scan PMOS tube in the display driving circuit 112 . The present application does not limit the number and specific types of display test signals output by the display driving circuit 112 .

[0078] The touch signal may be two touch receiving signals (Touch_RX1 and Touch_RX2), or two touch driving signals (Touch_TX1 and Touch_TX2), etc. The present application does not limit the number and specific types of touch signals.

[0079] For example, the touch electrodes may include at least one of touch receiving electrodes and touch driving electrodes. The touch receiving electrodes may output touch receiving signals, and the touch driving electrodes may input touch driving signals.

[0080] For example, refer to Figure 8, the touch electrode 122 may include: a touch receiving electrode 1221 and a touch driving electrode 1222; the touch signal trace 152 includes a touch receiving signal trace and a touch driving signal trace; the number of target conductive contact pads 1311 is M, and the M target conductive contact pads 1311 include a third target conductive contact pad 13113 and a fourth target conductive contact pad 13114; M is an integer greater than 1; The touch receiving electrode 1221 is connected to the third target conductive contact piece 13113 through a touch receiving signal wiring; the touch driving electrode 1222 is connected to the fourth target conductive contact piece 13114 through a touch driving signal wiring.

[0081] In addition, in practical applications, the number of conductive contact pads required for touch receiving electrodes is generally equivalent to the number of conductive contact pads required for touch driving electrodes, and the number of conductive contact pads required for touch receiving electrodes is generally equivalent to the number of conductive contact pads for display signal test points. Considering the consistency of load, the embodiment of the present application can use the conductive contact pads required for the entire group of touch receiving electrodes and reuse the conductive contact pads for display signal test points to ensure the consistency of load for the entire group of touch receiving electrodes. Alternatively, the conductive contact pads required for the entire group of touch driving electrodes are used and the conductive contact pads for display signal test points are reused to ensure the consistency of load for the entire group of touch driving electrodes. If in other embodiments, a part of the conductive contact pads required for touch receiving electrodes and a part of the conductive contact pads required for touch driving electrodes are used and the conductive contact pads for display signal test points are reused, the load of the entire group of touch receiving electrodes and the load of the entire group of touch driving electrodes may be inconsistent, affecting the touch reception and driving performance.

[0082] In the embodiment of the present application, in the first working state, the control signal of the first switch 160 is high level, the first switch 160 is turned on, the display driving circuit 112 can output the display test signal normally without additional requirements, and the touch electrode 122 does not receive or send any touch signal (which can be achieved by the touch chip sleeping) to avoid the touch signal from interfering with the display test signal. In addition, in the first working state, the control signal of the second switch 170 is low level, the second switch 170 is turned off, and the touch signal line 152 is interrupted, which can avoid the risk of distortion of the display test signal caused by the load of the touch signal line 152 and the touch electrode 122.

[0083] In the second working state, the control signal of the first switch 160 is at a low level, the first switch 160 is disconnected, and the display driving circuit 112 can output the display test signal normally without additional requirements. However, since the first switch 160 is disconnected, the display test signal wiring 142 is interrupted, and there is no display test signal on the target metal contact piece, which will not interfere with the touch signal. In addition, in the second working state, the control signal of the first switch 160 is at a low level, the first switch 160 is disconnected, and the display test signal wiring 142 is interrupted, which can avoid the risk of distortion of the touch signal caused by the load of the display test signal wiring 142 and the display driving circuit 112.

[0084] In this way, the display driving circuit 112 and the touch electrode 122 reuse the target conductive contact pads through the display test signal routing 142 and the touch signal routing 152, further reducing the number of conductive contacts in the gold finger, and thus more conductive contacts can be reserved in the gold finger for display signals. Furthermore, since the number of conductive contacts in the gold finger is reduced, the yield (or performance) risk caused by the need to reduce the line width and line spacing of a single conductive contact due to size limitations can be further reduced.

[0085] In another specific embodiment, taking the first functional module 110 realizing the electromagnetic pen function of the display panel and the second functional module 120 realizing the finger touch function of the display panel as an example, Fig. 9 As shown, the first functional module 110 includes an electromagnetic pen electrode 113, and the first functional wiring 140 includes an electromagnetic pen signal wiring 143; the second functional module 120 includes a touch electrode 123, and the second functional wiring 150 includes a touch signal wiring 153; The electromagnetic pen electrode 113 is connected to the target conductive contact piece through the electromagnetic pen signal wiring 143 ; the touch electrode 123 is connected to the target conductive contact piece through the touch signal wiring 153 .

[0086] The electromagnetic pen electrode can output an electromagnetic pen signal, and the touch electrode can output a touch signal.

[0087] For example, the electromagnetic pen electrode may include at least one of an electromagnetic pen transverse electrode and an electromagnetic pen longitudinal electrode. The electromagnetic pen transverse electrode may include at least one, and the electromagnetic pen longitudinal electrode may include at least one. The electromagnetic pen transverse electrode may output an electromagnetic pen transverse electrode signal, and the electromagnetic pen longitudinal electrode may output an electromagnetic pen longitudinal electrode signal.

[0088] For example, the touch electrodes may include at least one of touch receiving electrodes and touch driving electrodes. The touch receiving electrodes may output touch receiving signals, and the touch driving electrodes may input touch driving signals.

[0089] For example, refer to Fig. 9, the electromagnetic pen electrode 113 may include: an electromagnetic pen transverse electrode 1131 and an electromagnetic pen longitudinal electrode 1132; the electromagnetic pen signal trace 143 includes an electromagnetic pen transverse electrode signal trace and an electromagnetic pen longitudinal electrode signal trace; the number of target conductive contact pads 1311 is N, and the N target conductive contact pads 1311 include a first target conductive contact pad 13115 and a second target conductive contact pad 13116; N is an integer greater than 1; The electromagnetic pen transverse electrode 1131 is connected to the first target conductive contact piece 13115 through the electromagnetic pen transverse electrode signal wiring; the electromagnetic pen longitudinal electrode 1132 is connected to the second target conductive contact piece 13116 through the electromagnetic pen longitudinal electrode signal wiring.

[0090] And, reference Fig. 9 The touch electrodes 123 may include touch receiving electrodes 1231 and touch driving electrodes 1232 ; the touch signal wiring 153 may include touch receiving signal wiring and touch driving signal wiring.

[0091] Among them, the number of target conductive contacts 1311 is M (M equals N), and the M target conductive contacts 1311 include a third target conductive contact and a fourth target conductive contact; wherein the third target conductive contact and the above-mentioned first target conductive contact 13115 can be the same target conductive contact, and the fourth target conductive contact and the above-mentioned second target conductive contact 13116 can be the same target conductive contact.

[0092] The touch receiving electrode 1231 is connected to the third target conductive contact piece through a touch receiving signal wiring; and the touch driving electrode 1232 is connected to the fourth target conductive contact piece through a touch driving signal wiring.

[0093] In the embodiment of the present application, in the first working state, the control signal of the first switch 160 is high level, the first switch 160 is turned on, the electromagnetic pen electrode 113 can output the electromagnetic pen signal normally, and the touch electrode 123 does not receive or send any touch signal (which can be achieved by the touch chip sleep), so as to avoid the touch signal from interfering with the electromagnetic pen signal. In addition, in the first working state, the control signal of the second switch 170 is low level, the second switch 170 is turned off, and the touch signal wiring 153 is interrupted, which can avoid the risk of electromagnetic pen signal distortion caused by the load of the touch signal wiring 153 and the touch electrode 123.

[0094] In the second working state, the control signal of the first switch 160 is low level, the first switch 160 is disconnected, and the electromagnetic pen electrode 113 does not receive or send any electromagnetic pen signal (which can be achieved by putting the electromagnetic pen control chip into sleep mode) to avoid interference of the electromagnetic pen signal with the touch signal. In addition, in the second working state, the control signal of the first switch 160 is low level, the first switch 160 is disconnected, and the electromagnetic pen signal wiring 143 is interrupted, which can avoid the risk of distortion of the touch signal caused by the load of the electromagnetic pen signal wiring 143 and the electromagnetic pen electrode 113.

[0095] In this way, the electromagnetic pen electrode 113 and the touch electrode 123 reuse the target conductive contact 1311 through the electromagnetic pen signal routing 143 and the touch signal routing 153, further reducing the number of conductive contacts in the gold finger, and thus more conductive contacts can be reserved in the gold finger for display signals. Furthermore, since the number of conductive contacts in the gold finger is reduced, the yield (or performance) risk caused by the need to reduce the line width and line spacing of a single conductive contact due to size limitations can be further reduced.

[0096] Based on the same concept of the display panel provided in any of the above embodiments, an embodiment of the present application further provides an electronic device, which is described below by example.

[0097] like Fig.10 As shown, an embodiment of the present application provides an electronic device 10, which may include a display panel 100 provided by any of the above embodiments, and may implement all functions of the display panel 100. To avoid repetition, they will not be described again here.

[0098] In a specific embodiment, referring to Figure 11, the electronic device 10 provided in the embodiment of the present application may further include a flexible circuit board 200, and the flexible circuit board 200 may include a first functional element 210, a second functional element 220, a third functional wiring 240 and a fourth functional wiring 250; the first functional element 210 is connected to the third functional wiring 240, and the second functional element 220 is connected to the fourth functional wiring 250; the third functional wiring 240 and the fourth functional wiring 250 are respectively connected to the target conductive contact sheet 1311; In the first working state, the target conductive contact 1311 is connected to the first functional element 210 via the third functional wiring 240 ; in the second working state, the target conductive contact 1311 is connected to the second functional element 220 via the fourth functional wiring 250 .

[0099] It should be pointed out that the flexible circuit board 200 also has a gold finger 230. The gold finger 230 on the flexible circuit board 200 is similar to the gold finger 130 on the display panel. The gold finger 230 on the flexible circuit board also includes multiple conductive contacts. A conductive contact on the flexible circuit board can be bonded to a conductive contact on the display panel through a conductive glue, so that the gold finger 230 on the flexible circuit board is connected to the gold finger 130 on the display panel.

[0100] In this way, the first functional element 210 and the second functional element 220 on the flexible circuit board 200 reuse the conductive contacts through the third functional trace 240 and the fourth functional trace 250 respectively, which can correspondingly reduce the number of conductive contacts required for the gold fingers on the flexible circuit board.

[0101] In actual application scenarios, the first functional element 210 and the second functional element 220 can realize different functions in different time periods. For example, the first functional element 210 can be used to assist in realizing the test function of the display panel, and the second functional element 220 can be used to assist in realizing the electromagnetic pen function of the display panel. For another example, the first functional element 210 can be used to assist in realizing the test function of the display panel, and the second functional element 220 can be used to assist in realizing the finger touch function of the display panel. For another example, the first functional element 210 can be used to assist in realizing the electromagnetic pen function of the display panel, and the second functional element 220 can be used to assist in realizing the finger touch function of the display panel. The following is a specific description of the specific application scenario.

[0102] In a specific embodiment, Fig.12 As shown, in the electronic device, the display panel 100 may be as shown in FIG. Figure 7-1 Correspondingly, the first functional element 210 can be used to assist in realizing the test function of the display panel, and the second functional element 220 can be used to assist in realizing the electromagnetic pen function of the display panel.

[0103] like Fig.12 As shown, in the case where the first functional module 110 includes a display driving circuit 111 and the second functional module 120 includes an electromagnetic pen electrode 121, the first functional element 210 includes at least one test point 211; the second functional element 220 includes an electromagnetic pen control chip 221; When the target conductive contact sheet 1311 is in the first working state, the electromagnetic pen control chip 221 is in the dormant state.

[0104] In this way, in the first working state, the control signal of the first switch 160 is at a high level, the first switch 160 is turned on, and the display driving circuit 111 can output the display test signal normally without additional requirements. Since the electromagnetic pen control chip 221 is in a sleep state, the electromagnetic pen control chip 221 does not receive or send any electromagnetic pen signal, which can prevent the electromagnetic pen signal received or output by the electromagnetic pen control chip 221 from conflicting with the display test signal, thereby avoiding the electromagnetic pen signal from interfering with the display test signal.

[0105] In another specific embodiment, Fig.13 As shown, in the electronic device, the display panel 100 may be as shown in FIG. Figure 8 Correspondingly, the first functional element 210 can be used to assist in realizing the test function of the display panel, and the second functional element 220 can be used to assist in realizing the touch function of the display panel.

[0106] like Fig.13 As shown, in the case where the first functional module 110 includes a display driving circuit 112 and the second functional module 120 includes a touch electrode 122, the first functional element 210 includes at least one test point 212, and the second functional element 220 includes a touch chip 222; When the target conductive contact sheet 1311 is in the first working state, the touch control chip 222 is in the dormant state.

[0107] In this way, in the first working state, the control signal of the first switch 160 is at a high level, the first switch 160 is turned on, and the display driving circuit 112 can output the display test signal normally without additional requirements. Since the touch chip 222 is in a sleep state, the touch chip 222 does not receive or send any touch signal, which can prevent the touch signal received or output by the touch chip 222 from conflicting with the display test signal, thereby avoiding the touch signal from interfering with the display test signal.

[0108] In another specific embodiment, Fig.14 As shown, in the electronic device, the display panel 100 may be as shown in FIG. Fig. 9 Correspondingly, the first functional element 210 can be used to assist in realizing the touch function of the display panel, and the second functional element 220 can be used to assist in realizing the electromagnetic pen function of the display panel.

[0109] like Fig.14 As shown, in the case where the first functional module 110 includes the electromagnetic pen electrode 113 and the second functional module 120 includes the touch control electrode 123, the first functional element 210 includes the electromagnetic pen control chip 213, and the second functional element 220 includes the touch control chip 223; When the target conductive contact sheet 1311 is in the first working state, the touch control chip 223 is in the dormant state; when the target conductive contact sheet 1311 is in the second working state, the electromagnetic pen control chip 213 is in the dormant state.

[0110] Thus, in the first working state, the control signal of the first switch 160 is high level, the first switch 160 is turned on, the electromagnetic pen control chip 213 can normally receive or output the electromagnetic pen signal, and because the touch chip 223 is in a dormant state, the touch chip 223 does not receive or send any touch signal, which can prevent the touch signal received or output by the touch chip 223 from conflicting with the electromagnetic pen signal, and avoid the touch signal from interfering with the electromagnetic pen signal. In the second working state, the control signal of the second switch 170 is high level, the second switch 170 is turned on, the touch chip 223 can normally receive or output the touch signal, and because the electromagnetic pen control chip 213 is in a dormant state, the electromagnetic pen control chip 213 does not receive or send any electromagnetic pen signal, which can prevent the electromagnetic pen signal received or output by the electromagnetic pen control chip 213 from conflicting with the touch signal, and avoid the electromagnetic pen signal from interfering with the touch signal.
