[0007] The non-display area is provided with a multi-way splitter circuit, which is used to output data signals to the multiple data lines in a time-division manner. The multi-way splitter circuit includes multiple control lines and multiple thin-film transistors. The gate of each thin-film transistor is connected to one of the control lines, and the drain of each thin-film transistor is connected to one of the data lines.

[0008] An electrostatic discharge unit is provided between two adjacent control lines, and the electrostatic discharge unit is used to release the electrostatic charge in the control lines.

[0009] Based on the above display panel, optionally, the electrostatic discharge unit includes a first component and a second component; the first component and the second component are respectively connected to one of the two adjacent control lines;

[0010] The first component includes a first electrostatic discharge section, and the second component includes a second electrostatic discharge section. The first electrostatic discharge section and the second electrostatic discharge section are arranged in parallel to form an electrostatic discharge structure for releasing electrostatic charge.

[0011] Based on the above display panel, optionally, the first component includes a plurality of first electrostatic discharge parts, and the second component includes a plurality of second electrostatic discharge parts. The plurality of first electrostatic discharge parts and the plurality of second electrostatic discharge parts are arranged alternately, so that any first electrostatic discharge part and a second electrostatic discharge part are arranged parallel and overlapping.

[0012] Based on the above display panel, optionally, the first electrostatic discharge part is a first strip structure, the second electrostatic discharge part is a second strip structure, the first strip structure and the second strip structure extend towards each other, the first strip structure and the second strip structure are arranged in parallel, and the first strip structure and the second strip structure overlap in a direction perpendicular to their extension direction.

[0013] Based on the above display panel, optionally, the number of electrostatic discharge units between adjacent control lines is multiple.

[0014] Based on the above display panel, optionally, the control line includes a first sub-line and a second sub-line connected to each other. The first sub-line is disposed on the same layer as the gate of the thin-film transistor, and the second sub-line is disposed on the same layer as the drain of the thin-film transistor. The first sub-line is connected to a control signal input terminal, which is used to input a control signal to the control line, and the second sub-line is connected to the gate of the thin-film transistor.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below in conjunction with the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Application Overview

[0032] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of an existing display panel. The display panel 1 includes a display area 11 and a non-display area 12 disposed on at least one side of the display area 11.

[0033] The display area 11 includes multiple arrayed sub-pixels 21, multiple data lines 22, and multiple gate lines 23; the non-display area 12 includes a data driving circuit 24 and a gate driving circuit 25.

[0034] Multiple data lines 22 are connected to a data driving circuit 24 and, driven by the data driving circuit 24, provide data signals to multiple sub-pixels 21 respectively. Multiple gate lines 23 are connected to a gate driving circuit 25 and, driven by the gate driving circuit 25, provide gate driving signals to multiple sub-pixels 21 respectively. Each sub-pixel 21 emits light under the combined action of the corresponding data signal and gate driving signal, thereby ultimately realizing the display function of the display panel. It should be noted that, unless otherwise specified, "multiple" in various parts of this invention refers to at least two lines, and similarly, "multiple" refers to at least two lines.

[0035] In practice, to reduce costs and other reasons, the number of output channels of the data driver circuit 24 is usually reduced. To achieve this, refer to... Figure 2The display panel includes a multiplexer circuit 26 at the output of the data driver circuit 24. A multiplexer (Demultiplexer, Demux), also known as a data distributor, demodulator, or demultiplexer, is a combinational logic circuit that sends input signals to designated outputs based on different states of the input address code. In this scheme, the multiplexer circuit 26 is used to output data signals to multiple data lines 22 in a time-division manner. Specifically, the multiplexer circuit 26 includes one input and at least two outputs. Figure 2 (Only two are shown in the figure), in which, by controlling the input terminal of the multiplexer circuit 26 to be connected to different output terminals at different times, the same output channel of the data drive circuit 24 can be controlled to provide data signals to different data lines 22.

[0036] Furthermore, during the manufacturing process of the display panel, AT testing is required. During AT testing, various circuits, including multiplexers, need to be connected to the AT circuit and tested using the AT circuit. Inevitably, static electricity will be introduced from the AT circuit into the display panel during this testing process. For example, in some designs, the multiplexer uses thin-film transistors to perform the distribution function. Static electricity may accumulate at the thin-film transistors of the multiplexer. When the accumulated static charge reaches a certain value, electrostatic discharge (ESD) may occur, which may damage the thin-film transistors, thereby affecting the final display performance of the display panel and even affecting the normal use of the product.

[0037] To address the issue of electrostatic discharge (ESD) damage, some solutions extend the length of the connection line between the multiplexer and the AT circuit, thus increasing the distance static electricity travels from the AT circuit to the multiplexer. This spreads the static charge along the path from the AT circuit to the multiplexer, reducing the likelihood of ESD. Other solutions incorporate barrier structures made of materials such as P-Si (P-type silicon) along the path from the AT circuit to the multiplexer to provide some protection against ESD. However, when the amount of static charge is significant, none of these solutions can completely prevent ESD damage to the thin-film transistors in the multiplexer.

[0038] Based on this, the present invention provides another solution to improve the problem of electrostatic discharge (ESD) injury. The following examples or embodiments illustrate specific implementation schemes in a non-limiting manner.

[0039] Exemplary display panel

[0040] Continue to refer to Figure 1 , Figure 2 and refer to Figure 3 and Figure 4 ,in, Figure 3This is a partial top view of the multi-channel splitter circuit of a display panel provided in one embodiment of the present invention. Figure 4 for Figure 3 The circuit schematic. First, it should be noted that... Figure 3 In this context, structures with the same fill pattern are located on the same layer of the display panel, while structures with different fill patterns are located on different layers of the display panel. Figure 3 The "square A" with black fill indicates that structures on different layers are electrically connected to each other through the connection structure here. Figure 1 and Figure 2 Based on the display panel shown, as Figure 3 and Figure 4 As shown, the multiplexer circuit 26 of the display panel in this embodiment includes multiple control lines 261 and multiple thin-film transistors 262. The gate G of each thin-film transistor 262 is connected to one of the control lines 261, and the drain D of each thin-film transistor 262 is connected to one of the data lines. Furthermore, an electrostatic discharge unit 27 is provided between two adjacent control lines 261, and the electrostatic discharge unit 27 is used to release the electrostatic charge in the control lines 261.

[0041] Specifically, the working principle of the multiplexer circuit 26 is as follows: the source S of the thin-film transistor 262 in the multiplexer circuit 26 is connected to the output channel of the data drive circuit. Figure 3 and Figure 4 The data driving circuit (not shown) is used to receive data signals; the gate G is connected to one of the control lines 261 of the multiplexer circuit 26 to control the conduction and cutoff of the source S and drain D; the drain D is connected to the driving transistor of the driven sub-pixel (not shown) through the data line. Since the data signal can be transmitted to the corresponding sub-pixel when the source S of the thin film transistor 262 receives the data signal and is turned on by the drain D, different control signals are output through different control lines 261 at different times, so that different thin film transistors 262 are turned on, that is, data signals can be output to different data lines in the end.

[0042] During AT testing, the multiple control lines 261 of the multiplexer circuit 26 are connected to the ATPAD (pads) of the AT circuit, inevitably introducing static electricity. This static charge accumulates on the control lines 261, causing a change in the gate voltage (G) of the thin-film transistor (TFT) 262. As the static charge accumulates, the voltage difference between the gate (G) and the source (S) (and / or drain (D)) increases. When the voltage difference reaches a certain value, a discharge occurs, causing the gate (G) and source (S) (and / or drain (D)) to break down, leading to the failure of the TFT 262. After the TFT 262 fails, some data lines cannot receive data signals from the data drive circuit, thus affecting the display effect of the display panel.

[0043] In this embodiment, an electrostatic discharge unit 27 is provided between at least two adjacent control lines 261. Since the amount of electrostatic charge accumulated on adjacent control lines 261 is usually different, when electrostatic charge accumulates on control lines 261, if the voltage difference between two adjacent control lines 261 increases to a certain value, discharge will occur at the electrostatic discharge unit 27, thereby releasing the accumulated electrostatic charge and preventing the electrostatic charge from discharging at a certain thin-film transistor 262, thus preventing the thin-film transistor 262 from being broken down.

[0044] It should be noted that, Figure 3 In the corresponding embodiment, the number of control lines 261 shown is 4, that is, the 4 control lines 261 are mux1, mux2, mux3 and mux4 respectively. However, it is understood that this is only exemplary. In fact, the number of control lines 261 is not limited to 4 and can be adjusted to more or fewer according to actual needs.

[0045] also, Figure 3 In the corresponding embodiment, an electrostatic discharge unit 27 is provided between each pair of adjacent control lines 261. This allows for discharge when the voltage difference caused by static electricity accumulation between any two adjacent control lines 261 exceeds a specific value, thereby effectively protecting the thin-film transistors 262 connected to all control lines 261. However, it is understood that in other embodiments, the electrostatic discharge unit 27 may only be provided between some adjacent pairs of control lines 261; for example, the electrostatic discharge unit 27 may be omitted. Figure 3 The electrostatic discharge unit 27 between the control lines mux1 and mux2 can still achieve electrostatic protection to a certain extent, preventing the thin-film transistor 262 from being electrostatically damaged.

[0046] In addition, such as Figure 3As shown, the number of electrostatic discharge units 27 between adjacent control lines 261 can be multiple (three are shown in the figure). This increases the area and surface area for electrostatic discharge, making it easier to perform electrostatic discharge and better achieving electrostatic protection.

[0047] The working principle of the electrostatic discharge unit 27 of the present invention has been explained above. The specific implementation scheme that can realize the above principle will be described below with reference to the accompanying drawings.

[0048] Reference Figure 5 , Figure 5 for Figure 3 An enlarged view of the electrostatic discharge unit in the image. (See image for reference.) Figure 5 As shown, in this embodiment, the electrostatic discharge unit 27 includes a first component 271 and a second component 272; the first component 271 and the second component 272 are respectively connected to one of two adjacent control lines 261; the first component 271 includes a first electrostatic discharge section 271a, and the second component 272 includes a second electrostatic discharge section 272a; the first electrostatic discharge section 271a and the second electrostatic discharge section 272a are arranged in parallel to form an electrostatic discharge structure for releasing electrostatic charge.

[0049] And, as Figure 3 and Figure 5 As shown, the first electrostatic discharge unit 271a and the second electrostatic discharge unit 272a are respectively connected to the corresponding control line 261 via the first connecting part 271b and the second connecting part 272b, realizing electrical connection with the corresponding control line 261. This allows the electrostatic charge on the corresponding control line 261 to be transferred to the first electrostatic discharge unit 271a and the second electrostatic discharge unit 272a. Since the first electrostatic discharge unit 271a and the second electrostatic discharge unit 272a are arranged in parallel with a very small gap, discharge can occur when the voltage difference between them reaches a small value. This prevents the electrostatic charge on the control line 261 from continuing to propagate towards the thin-film transistor 262, thus protecting the thin-film transistor 262.

[0050] Furthermore, continue to refer to Figure 5As shown, the first component 271 includes a plurality of first electrostatic discharge portions 271a, and the second component 272 includes a plurality of second electrostatic discharge portions 272a. The plurality of first electrostatic discharge portions 271a and the plurality of second electrostatic discharge portions 272a are arranged alternately, such that any first electrostatic discharge portion 271a is parallel to and overlaps with a second electrostatic discharge portion 272a. Thus, by arranging the plurality of first electrostatic discharge portions 271a and the plurality of second electrostatic discharge portions 272a alternately, and with any first electrostatic discharge portion 271a parallel to and overlapping with a second electrostatic discharge portion 272a, multiple electrostatic discharge structures can be formed, increasing the area available for electrostatic discharge, increasing the possibility of electrostatic discharge, and better achieving the electrostatic protection function.

[0051] Of course, it is understandable that there may be only one first electrostatic discharge section 271a and / or second electrostatic discharge section 272a. Furthermore, Figure 5 In some embodiments, there are two first electrostatic discharge units 271a and two electrostatic discharge units 272a. However, in other embodiments, there are three or more first electrostatic discharge units 271a and two electrostatic discharge units 272a. That is to say, the present invention does not limit the number of first electrostatic discharge units 271a and two electrostatic discharge units 272a in each electrostatic discharge unit 27, and the design can be made according to actual needs.

[0052] And, as Figure 5 As shown, the first electrostatic discharge section 271a is a first strip-shaped structure, and the second electrostatic discharge section 272a is a second strip-shaped structure. The first and second strip-shaped structures extend towards each other and are arranged parallel to each other, overlapping in a direction perpendicular to their extension direction. By making both the first and second electrostatic discharge sections 271a and 272a strip-shaped structures, the area occupied by the first and second electrostatic discharge sections 271a and 272a can be reduced while ensuring their parallelism. This facilitates the placement of the first and second electrostatic discharge sections 271a and 272a between adjacent control lines 261 during actual fabrication.

[0053] also, Figure 5 In the electrostatic discharge unit 27 shown, the first electrostatic discharge section 271a and the second electrostatic discharge section 272a are perpendicular to the extension directions of their respective corresponding connecting sections, which facilitates the formation of each part of the electrostatic discharge unit 27 in actual manufacturing processes. However, it is understood that the function can still be achieved even when the extension directions of the first electrostatic discharge section 271a and the second electrostatic discharge section 272a are not perpendicular to their respective connecting sections.

[0054] Continue to refer to Figure 3In some embodiments, the control line 261 includes a first sub-line 261a and a second sub-line 261b connected to each other. The first sub-line 261a is disposed on the same layer as the gate G of the thin-film transistor 262, and the second sub-line 261b is disposed on the same layer as the drain D of the thin-film transistor 262 (the gate G and the drain D are on different layers). The first sub-line 261a is connected to a control signal input terminal, which is used to input a control signal to the control line 261. The second sub-line 261b is connected to the gate G of the thin-film transistor 262. The electrostatic discharge unit 27 is electrically connected to the first sub-line 261a.

[0055] Specifically, in the actual fabrication process, the thin-film transistor 262 and the control line 261 are formed in specific process stages. For example, in some embodiments, a first metal layer (which may be referred to as metal layer M1 in the art) may be formed on other previously formed film layer structures (such as buffer layer or insulating layer), and the first metal layer may be etched to form the gate G in the corresponding region of the thin-film transistor 262 and the first sub-line 261a of the control line 261 in the corresponding region of the control line 261. Next, an entire insulating layer is formed on top of it, and then specific locations on the insulating layer are etched to form vias for the connection lines to pass through. Then, an entire third metal layer (referred to in the art as metal layer M3) is formed on the insulating layer, and the entire third metal layer is etched to form the drain D (and source S) in the corresponding regions of the drain D (and source S), and the second sub-line 261b of the control line 261 in the corresponding region of the control line 261. The second sub-line 261b and the first sub-line 261a are interconnected through vias previously etched on the insulating layer. Thus, the thin-film transistor 262 and the control line 261 are fabricated. Based on this, the first sub-line 261a can obtain a control signal from a connected control signal input terminal (not shown in the figure) and control the state of the gate G through the second sub-line 261b, thereby controlling the source S and drain D of the thin-film transistor 262 to be turned on or off.

[0056] Furthermore, since the first sub-line 261a is farther away from the thin-film transistor 262 than the second sub-line 261b, the electrostatic discharge unit 27 is electrically connected to the first sub-line 261a. In other words, the electrostatic discharge unit 27 is set at a position relatively far away from the thin-film transistor 262, which can better prevent electrostatic discharge from damaging the thin-film transistor 262 and also better prevent the electrostatic discharge unit 27 from affecting the thin-film transistor 262 when discharging electrostatic discharge.

[0057] Based on this, in some embodiments, the electrostatic discharge unit 27 can be disposed in the same layer as the first sub-line 261a. In this way, the electrostatic discharge unit 27 can be etched and formed in the same process stage as the first sub-line 261a, thereby avoiding a significant increase in process steps.

[0058] In other embodiments, considering that in some scenarios the resistivity of the second sub-line 261b (e.g., a three-layer metal structure of titanium, aluminum, and titanium) is generally lower than that of the first sub-line 261a (e.g., molybdenum), the electrostatic discharge unit 27 can be disposed in the same layer as the second sub-line 261b when the resistivity of the second sub-line 261b is lower than that of the first sub-line 261a. That is, the electrostatic discharge unit 27 can be etched and formed in the same process stage as the second sub-line 261b, and the electrostatic discharge unit 27 (through a via on the insulating layer) can be electrically connected to the first sub-line 261a. Thus, compared to the scheme of setting the electrostatic discharge unit 27 and the first sub-line 261a on the same layer, although it requires additional process steps (that is, it requires additional steps to form vias for connecting the electrostatic discharge unit 27 and the first sub-line 261a), since the resistivity of the second sub-line 261b is less than that of the first sub-line 261a, static electricity is more easily released on the electrostatic discharge unit 27, thereby achieving a better protection function.

[0059] Furthermore, in practice, since there is also an insulating layer between the second sub-line 261b and the connection line of the drain D (the connection line of the drain D refers to the connection line between the drain D and the data line), when static electricity is released on the static discharge unit 27 in the same layer as the second sub-line 261b, this insulating layer can act as a protective layer to prevent the connection line of the drain D from being affected.

[0060] In addition, continue to refer to Figure 3 In practice, in existing solutions, the spacing between two adjacent first sub-lines 261a is generally equal to the spacing between two adjacent second sub-lines 261b. However, in this case, because the spacing between some adjacent first sub-lines 261a is small, it may be inconvenient to set up electrostatic discharge units 27 between adjacent first sub-lines 261a. Based on this, in some embodiments, the position of some first sub-lines 261a can be appropriately adjusted. Figure 3 The adjusted positions of each first sub-line 261a are shown, such that the distance between two adjacent first sub-lines 261a is greater than the distance between two adjacent second sub-lines 261b, thereby enabling the electrostatic discharge unit 27 to be disposed in the gap between two adjacent first sub-lines 261a.

[0061] It should be noted that, in addition to the structures and films mentioned in the above embodiments, the display panel also includes other structures and films necessary to realize its function, but the present invention does not modify them, so they will not be described in detail.
