Description

Technical Field

[0001] The present invention relates to the technical field of display panel design and manufacturing, and in particular to a touch display panel and a display device. Background Art

[0002] With the continuous development of display panel manufacturing technology, people have put forward higher requirements on the quality and performance of touch display panels and devices.

[0003] Touch display technology has been gradually applied to various types of display devices. The touch display panel has the function of direct manual touch operation, which is convenient to use and simple to interact with, so it is favored by the market. When preparing a touch display panel, it is usually necessary to set up multiple touch electrodes and touch wiring. The setting method of these touch wiring directly affects the performance of the touch panel. With the popularization of full-screen narrow-frame display technology, in traditional touch display panels, when setting the drive wiring and sensing wiring corresponding to the above-mentioned different touch wirings, it is often necessary to reserve a larger frame area to arrange the above wirings, such as reserving a certain width frame in the bottom area of ​​the panel to accommodate the above-mentioned drive wiring and sensing wiring. When the drive wiring and the sensing wiring extend to the bottom area, they will also be arranged in the bottom area so that the different touch wirings are electrically connected to the corresponding control signal lines. However, in the prior art, when setting the above-mentioned drive wiring and sensing wiring, the drive wiring will occupy the position of the sensing wiring. At the same time, the sensing wiring extends longer in the bottom frame and has a larger resistance. Moreover, in this area, the wiring is densely arranged, and there is serious mutual interference between different signal wirings. When the display panel is touched and the touch signal is transmitted, the above-mentioned sensing wiring with larger resistance and other densely arranged touch wiring will affect the yield of touch reporting, thereby reducing the touch performance of the panel.

[0004] In summary, when the touch lines of the touch display panel prepared in the prior art are arranged in the bottom frame area, the resistance value of the sensing lines is relatively large, and the dense arrangement of the lines is not ideal, which is not conducive to improving the touch performance.

[0016] According to an embodiment of the present invention, the sensing signal wiring is insulated and arranged on the GOA wiring, and the driving signal wiring is arranged on the same layer as the sensing signal wiring.

[0017] According to one embodiment of the present invention, the sensing signal routing line further includes a bending section on a side of the bottom frame area close to the side frame area, the bending section bends toward one side of the second direction, and a projection of the bending section in the bottom frame area partially overlaps with the GOA routing line.

[0029] In conjunction with the accompanying drawings in the embodiments of the present invention, the following disclosure provides different implementation methods or examples to implement different structures of the present invention. In order to simplify the present invention, the components and settings of specific examples are described below. In addition, the examples of various specific processes and materials provided by the present invention are examples that ordinary technicians in the field can recognize the application of other processes. All other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0030] In the following detailed description, only certain embodiments of the present invention are shown and described simply by way of illustration. As those skilled in the art will appreciate, the embodiments described herein may be modified in various ways without departing from the spirit or scope of the present invention.

[0031] In the drawings, the thickness of layers, films, panels, regions, etc. may be exaggerated for clarity and for better understanding and ease of description. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present.

[0032] In addition, unless explicitly described to the contrary, the word "comprise" and its variations like "include" or "contain" will be understood to imply the inclusion of the discussed elements, but not necessarily the exclusion of other elements. Further, in the specification, the word "on..." refers to placement above or below an object part, and does not necessarily mean placement on the upper side of an object part based on the direction of gravity.

[0033] It will be understood that although the terms "first", "second", etc. may be used herein to describe various components, these components should not be limited by these terms. These components are only used to distinguish one component from another.

[0034] As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0035] It will also be understood that the terms “comprises” and / or “comprising” as used herein specify the presence of stated features or components, but do not exclude the presence or addition of one or more other features or components.

[0036] It will be understood that when a layer, region or component is referred to as being “formed on” another layer, region or component, it may be directly or indirectly formed on the other layer, region or component. For example, intervening layers, regions or components may be present.

[0037] In the following examples, the x-axis, y-axis, and z-axis are not limited to the three axes of the rectangular coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other.

[0038] In the embodiments of the present application, a touch display panel and a touch display device are provided to effectively improve the problem that the resistance value of the sensing wiring corresponding to the touch wiring in the narrow-frame touch display panel is large, thereby causing unsatisfactory touch effect and reporting rate.

[0039] like Figure 1 As shown, Figure 1 Schematic diagram of a planar structure of a touch display panel provided in an embodiment of the present application. The touch display panel includes a display area 101 and a frame area 11 arranged around the display area 101. The frame area 11 is mainly a non-display area of ​​the touch display panel. In the embodiment of the present application, when defining the above-mentioned frame area 11, when the touch display panel is a rectangular structure, the frame area 11 may include a bottom frame area 104, a first side frame area 102 and a second side frame area 103 arranged on both sides of the bottom frame area 104, and a top frame area arranged opposite to the bottom frame area.

[0040] Furthermore, a plurality of touch electrodes are arranged in the display area 101. For example, the touch electrodes are patterned in the display area, and the signals of the touch electrodes are led out through corresponding signal lines. When the panel is touched, the touch signals are transmitted through the signal lines, and the touch function of the display panel is realized.

[0041] In the embodiment of the present application, the touch electrode may include a sensing electrode and a driving electrode. At the same time, the sensing electrode transmits a signal through a sensing signal line 301, and the driving electrode transmits a touch signal through a driving signal line 302. Specifically, during the setting, the sensing signal line 301 (receive, RX) is led out from the display area 101 to the side frame area 11, such as Figure 1 In the embodiment, the sensing signal trace 301 is led out from the display area 101 to the first side frame area 102, and is extended in the first side frame area toward one side of the bottom frame area 104, such as being arranged in the side frame area along the first direction Y, and extending to the bottom frame area 104. The first direction Y may be parallel to the side frame of the display panel.

[0042] At the same time, the drive signal line 302 (transport, TX) extends in the display area 101 toward one side of the bottom frame area 104, and is led out from the display area 101 to the bottom frame area 104. When the drive signal line 302 close to the side frame area is extended downward to the bottom frame area 104, since the drive signal lines 302 on both sides are far away from the middle, the drive signal lines 302 also need to be arranged along the second direction X, such as the horizontal direction, and converge to the middle area.

[0043] Further, in the embodiment of the present application, a gate drive circuit 201 is also provided in the side frame area 11 on both sides, and the gate drive circuit 201 also includes a plurality of GOA routing lines 202. In the embodiment of the present application, the GOA routing lines 202 can realize the transmission of different control signals, such as the GOA routing lines including clock signal lines, voltage signal buses, digital signal lines, etc., and the plurality of GOA routing lines 202 are arranged along the side frame area, and extend into the bottom frame area 104, and are electrically connected to the driver integrated chip, thereby realizing the transmission purpose of the control signal. Optionally, when setting different types of signal lines in the above-mentioned GOA routing lines, some of the functional lines can be selected and arranged according to the structure in the embodiment of the present application, such as selecting the voltage signal line in the GOA routing line, and the voltage signal bus extends downward and is electrically connected to the output terminal on the bottom integrated chip, thereby realizing the transmission of the control signal on the integrated chip.

[0044] In the embodiment of the present application, since the above-mentioned different types of signal routings will all extend into the bottom frame area, the manner in which different signal routings are arranged in the bottom frame area will directly affect the size of their resistances and the influence relationship between them, thereby affecting their touch reporting yield and touch effect.

[0045] In the embodiment of the present application, when setting the above-mentioned routing lines in the bottom frame area 104, the GOA routing line 202, the sensing signal routing line 301 and the driving signal routing line 302 all have a first section 303, and each first section is a partial length corresponding to each signal routing line when entering the bottom frame area 104. The first section 303 is equivalent to an extension portion, which extends in the bottom frame area 104 through the extension portion and continues to be set downward to achieve electrical connection with other terminals. In the embodiment of the present application, the first section of each signal routing line is set on the side of the bottom frame area close to the display area. In the embodiment of the present application, the first section corresponding to each of the above-mentioned signal routing lines is an area with a certain length. Within this specific length area, each signal line is continuously set and continues to extend to the bottom of the bottom frame. In the following embodiments, the first section corresponding to each signal routing line may be a rectangular strip area set along the second direction X, see for details. Figure 1 In the bottom frame area, the first section of the GOA line 202 is located between the first section of the sensing signal line 301 and the first section of the driving signal line 302, and the first section of the sensing signal line 301 is arranged on a side close to the side frame area, see Figure 1 In the embodiment, the sensing signal wiring 301 is arranged on a side close to the first side frame area 102. In the embodiment of the present application, the above-mentioned first sections can be arranged along the first direction Y and parallel to each other.

[0046] In this way, by setting the sensing signal line 301 at the outermost edge position, when the sensing signal line 301 is routed along the second direction X, it only needs to travel a short distance to continue to converge downward, thereby reducing the overlapping area between the sensing signal line 301 and the GOA line 202 and the driving signal line 302, thereby effectively reducing the resistance value of the sensing signal line 301 and the interference problem of different signal lines.

[0047] like Figure 2 As shown, Figure 2 Provided in the embodiments of this application Figure 1 Simplified schematic diagram of the . Figure 1 In the routing structure, in the embodiment of the present application, when the above-mentioned different first sections are set, the distance D1 between the first section of the sensing signal routing 301 and the first section of the GOA routing 202 is less than or equal to the distance D2 between the first section of the GOA routing 202 and the driving signal routing 302.

[0048] Optionally, the difference between the distance D2 and the distance D1 is set between 150um and 220um. In this way, while ensuring the routing lengths of the sensing signal routing 301 and the GOA routing 202 in the bottom frame area, the length or area of ​​the overlapping areas between different signal routings can be avoided, thereby effectively avoiding mutual interference between different signal routings while reducing the resistance value of each routing.

[0049] Specifically, when setting the specific positional relationship of the above-mentioned different routings, the distance D1 between the first section of the sensing signal routing 301 and the first section of the GOA routing 202 is set to 10um to 400um. Optionally, the distance D1 is set to 50um, 200um, 220um or 250um, or is set according to different product requirements. At the same time, when setting the distance D2, the distance D2 can be set to 200um to 600um. Preferably, the distance D2 is set to 300um, 400um, 450um or other sizes. For example, when the distance D1 is set to 200um, the distance D2 is set to 400um, so that while ensuring sufficient routing length, the resistance value of the sensing signal routing 301 is reduced as much as possible, and the signal interference problem with other routings is effectively reduced, thereby improving its touch reporting yield and touch performance.

[0050] like Figure 3 As shown, Figure 3 This is a schematic diagram of the wiring of another touch display panel provided in an embodiment of the present application at the bottom frame area. Figure 2 In the structure, in the embodiment of the present application, when the above-mentioned GOA wiring 202, the sensing signal wiring 301 and the driving signal wiring 302 are set, on the side of the bottom frame area 104 close to the display area, the driving signal wiring 302 also includes a first horizontal segment 402, the sensing signal wiring 301 also includes a second horizontal segment 401, and the GOA wiring 202 also includes a third horizontal segment 403. The above-mentioned horizontal segments are all arranged along the second direction X direction, so that different wirings are bent and extended in the required direction to optimize the arrangement of the wiring in the bottom frame area.

[0051] During the setting, since the horizontal segments corresponding to different routing lines overlap, and the size of the overlapping area between different routing lines will affect the stability of each signal routing line during signal transmission. In the embodiment of the present application, in the bottom frame area 104, the third horizontal segment 403 and the first horizontal segment 402 have a first overlapping area, and at the same time, the second horizontal segment 401 and the third horizontal segment 403 have a second overlapping area, and the width of the first overlapping area is less than or equal to half of the width of the second horizontal segment 401 routing line, and at the same time, the width of the second overlapping area is less than or equal to half of the width of the first horizontal segment 402 routing line. In this way, since the size of the overlapping area between the different routing lines is limited, when the sensing signal routing line 301 and the driving signal routing line 302 and the GOA routing line 202 are transmitting signals, the crosstalk problem between different signals is effectively controlled, and the stability of signal transmission is guaranteed.

[0052] At the same time, setting different overlapping areas between the above-mentioned different routing lines can effectively improve the relative arrangement position relationship between the different routing lines, thereby reducing the spatial size of the routing lines in the bottom frame area and achieving a narrow frame.

[0053] Further, in the embodiment of the present application, in the display area and the side frame area, the sensing signal line 301 is insulated and arranged on the GOA line 202, such as a passivation layer or an insulating layer is arranged between the sensing signal line 301 and the GOA line 202, and at the same time, the driving signal line 302 can be arranged in the same layer as the sensing signal line 301. Optionally, when the above-mentioned driving signal line 302 and the sensing signal line 301 are arranged, such as on the side of the bottom frame area away from the display area, the driving signal line 302 can also be arranged on the sensing signal line 301 or at a corresponding position above it, such as an insulating layer is arranged between the driving signal line and the sensing signal line, and the wiring arrangement structure in the area is optimized by arranging the two signal lines in layers.

[0054] like Figure 4 As shown, Figure 4 This is a partial wiring diagram of the touch display panel provided in the embodiment of the present application. Figure 1-Figure 3 The structure in Figure 4 Only the arrangement of the sensing signal wiring 301 and the driving signal wiring 302 is shown. On the side of the bottom frame area 104 close to the first side frame area, the sensing signal wiring 301 needs to be bent at the rounded corner of the touch display panel. After bending, the first section of the bottom frame area can be changed from the vertical direction to the horizontal direction, and then extend downward to other areas of the bottom frame area.

[0055] See Figure 4In the embodiment of the present application, the sensing signal line 301 extends from the frame areas on both sides to the bottom frame area, and is symmetrically arranged in the bottom frame area relative to the axis of the touch display panel. In the embodiment of the present application, on the side of the bottom frame area 104 close to the first side frame area, the sensing signal line 301 also includes a bending section 405. Among them, the bending section 405 is mainly arranged at the rounded corner position of the touch display panel. And the two ends of the bending section 405 are respectively electrically connected to the sensing signal line arranged along the first direction in the first side frame area and the sensing signal line arranged along the second direction in the bottom frame area. And thus constitute a complete sensing signal line 301 in the embodiment of the present application.

[0056] In the embodiment of the present application, when the above-mentioned bending section 405 is set, the bending section 405 is bent toward one side of the second direction, so that the sensing signal line 301 becomes horizontal, and during the bending process, the projection of the bending section in the bottom frame coincides with part of the GOA line, so as to save the line layout and achieve a narrow frame.

[0057] Specifically, when the bending section of the sensing signal wiring 301 is bent, it includes a plurality of bending portions, and different bending portions have different angles with the second direction.

[0058] like Figure 5 As shown, Figure 5 It is a schematic diagram of the arrangement of the sensing signal routing in the bending section provided in the embodiment of the present application. In the embodiment of the present application, the bending portion may include a first bending portion 501 and a second bending portion 502, and the first bending portion 501 is close to one side of the first side frame area, and the second bending portion 502 is away from one side of the first side frame area. At the same time, each bending portion has an angle with the second direction X, such as the angle is sharply reduced α. In the embodiment of the present application, the above-mentioned angles corresponding to the different bending portions are different, and are away from the first side frame area, and the angle is less than the angle value at the position close to the first side frame area. In the embodiment of the present application, when the above-mentioned different bending portions are bent, the difference between the angles of the two adjacent bending portions is less than or equal to 23°. Optionally, the difference in the angle between the two adjacent bending portions is set to 12° or 15°, thereby effectively ensuring a smooth transition of the sensing signal routing and having an optimal arrangement structure, thereby improving touch performance.

[0059] In the embodiment of the present application, since a plurality of different sensing signal lines 301 need to be bent, in order to avoid the overlap between the sensing signal lines and other lines during the bending and to avoid forming a large resistance value, the line width of the bending portion corresponding to the middle area of ​​the bending portion is smaller than the line width of the bending portion at the edges of both sides of the bending section.

[0060] Furthermore, in the embodiment of the present application, when the above-mentioned bending section is set, the first bending portion 501 has a first width W1, and the second bending portion 502 has a second width W2, wherein the first width W1 is smaller than the second width W2, so that the wiring in the middle area with the largest bending angle is thinner, and more of the sensing signal wiring can be set in the smaller rounded area. At the same time, the resistance value of the sensing signal wiring is further reduced, so as to effectively improve the yield of the timing when the touch signal is transmitted. In the embodiment of the present application, after the above-mentioned structure is set, the resistance of the sensing signal wiring in the bottom frame area can be reduced from 2000 ohms in the prior art to 1000 ohms to 1300 ohms. Thereby effectively reducing the resistance value of the sensing signal wiring in this area and improving its touch effect and performance.

[0061] Furthermore, in the bottom frame area 104, a binding area is also provided on a side away from the display area, and a plurality of wire-changing holes are provided in the binding area, and the plurality of wire-changing holes can be arranged in sequence and spaced in the second direction. Since the above-mentioned GOA wiring, the sensing signal wiring 301 and the driving signal wiring 302 need to be switched to other film layers through the wire-changing holes and electrically connected to the corresponding control terminals, such as the above-mentioned sensing signal wiring and the driving signal wiring need to be switched through different wire-changing holes and electrically connected to the control signal lines in the touch display panel, such as the metal wiring corresponding to the source / drain in the panel, the signal transmission is realized.

[0062] Furthermore, the embodiment of the present application also provides a touch display device. Specifically, the touch display device includes the display panel provided in the embodiment of the present application, the display panel has high touch sensitivity and high reporting yield, and at the same time, the resistance value of the sensing signal wiring in the bottom frame area of ​​the display panel is small, and the overall performance is good.

[0063] In the embodiment of the present application, the touch display panel and the display device can be any product or component with display function and touch function, such as a mobile phone, a computer, an electronic paper, a display, etc., and the specific type is not specifically limited.

[0064] In summary, a touch display panel and a touch display device provided by an embodiment of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation modes of the present invention. The description of the above embodiments is only used to help understand the technical solution and core idea of ​​the present invention.
