Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
In order to solve the problem that the reliability of connection between a driving chip and a touch trace is reduced due to the fact that the via hole of the existing fan-out area is easily corroded, the embodiment of the application provides a display panel and a display device, and the display panel and the display device are described below with reference to the accompanying drawings.
For example, referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the application. The embodiment of the application provides a display device 1, and the display device 1 may include a display panel 10 and a housing 20, where the housing 20 is connected to the display panel 10 to carry the display panel 10. The display device 1 may be a mobile electronic device such as a mobile phone, a tablet, a computer, etc., and the display device 1 may also be a device with display and touch functions such as a computer device, a video playing device, a television, a vehicle-mounted computer, etc.
The display panel 10 is a component for displaying in the display device 1, and a user may perform a touch operation on the display panel 10 to achieve different playing effects. With the development of touch technology, the integration of touch panels and liquid crystal panels includes an "In-cell" method and an "On-cell" method, where In-cell refers to the embedding of touch panel functions into liquid crystal pixels, and On-cell refers to the embedding of touch panel functions between a color filter substrate and a polarizing plate. The present application is illustrated with respect to a display panel 10 prepared by an In-cell method. The driving chip and the touch wire cannot be connected in one-to-one correspondence due to the limitation of the setting positions of the driving chip and the touch wire. In the prior art, through holes are formed in the fan-out area to realize layer-changing transverse overline so as to realize corresponding connection between the driving chip and the touch control wiring. However, the via hole of the fan-out area is easily corroded, resulting in reduced connection reliability between the driving chip and the touch trace.
It should be noted that, the fan-out area may be understood as an area where the wires of the display area converge to the non-display area to present a fan-shaped wire arrangement, and thus, the fan-out area may correspond to a portion of the display area and a portion of the non-display area.
In order to solve the above-described problems, the embodiment of the present application improves the wiring manner of the display panel 10.
For example, please refer to fig. 1 in combination with fig. 2, fig. 2 is a schematic diagram of a first structure of a display panel in the display device shown in fig. 1. The display panel 10 may include a display area A-A and a non-display area B-B disposed around the display area A-A, it being understood that the non-display area B-B may be used for wiring, and at the same time, the non-display area B-B may be used for connection with the case 20, and a portion of the non-display area B-B connected with the case 20 may be referred to as a bezel area of the display device 1.
For example, please refer to fig. 3 and fig. 4 in combination with fig. 1 and fig. 2, fig. 3 is a schematic cross-sectional view of a portion of the structure of the display panel shown in fig. 2, and fig. 4 is a schematic second schematic structural view of the display panel of the display device shown in fig. 1. The display panel 10 may further include a pixel layer 11, a touch layer 12, a driving chip 13, a plurality of data traces 14, and a plurality of touch traces 15.
The pixel layer 11 may include a plurality of pixel electrodes 110, and the plurality of pixel electrodes 110 are disposed in the display regions A-A. For example, the plurality of pixel electrodes 110 may be arranged in an array of M rows and N columns in the display area A-A. The touch layer 12 is disposed on one side of the pixel layer 11, and the touch layer 12 includes a plurality of touch electrodes 120, and each touch electrode 120 is disposed corresponding to the plurality of pixel electrodes 110. It should be noted that the number of the touch electrodes 120 is less than the number of the pixel electrodes 110, and the area of each touch electrode 120 is greater than the area of each pixel electrode 110. For example, the touch electrodes 120 may be arranged in an array of K rows and L columns, and one touch electrode 120 may be disposed corresponding to the plurality of pixel electrodes 110. For example, each touch electrode 120 may be disposed corresponding to 50 rows and 50 columns of pixel electrodes 110.
Note that, the touch electrode 120 may also be referred to as a common electrode, and a capacitance or an amount of charge stored between the pixel electrode 110 and the common electrode is used to be transferred to the driving TFT (Thin Film Transistor ) to control the display of the display device 1. The capacitance or the charge amount formed between the touch electrode 120 and the finger of the user is used to transfer the position information touched by the finger to the driving chip 13, so that the display device 1 displays the preset picture information according to the position information touched by the finger.
For example, the driving chip 13 is disposed in the non-display area B-B of the display panel 10, and the driving chip 13 may include a plurality of touch pins 131 and a plurality of data pins 130. It should be noted that, the driving chip 13 may not only receive the position information of the finger touching the touch electrode 120, but also process the position information of the touched touch electrode 120 and transmit control information to the pixel electrode 110, so that the area corresponding to the touched touch electrode 120 displays the preset image information.
The plurality of data traces 14 are disposed on a side of the pixel layer 11 facing away from the touch layer 12, and the plurality of data traces 14 are respectively connected to the plurality of pixel electrodes 110 and the plurality of data pins 130. It should be noted that, each data trace 14 may be connected to a row of pixel electrodes 110, and then a row of pixel electrodes 110 is correspondingly connected to one data pin 130, and a plurality of rows of pixel electrodes 110 are correspondingly connected to a plurality of data pins 130.
The plurality of touch traces 15 and the plurality of data traces 14 are disposed at the same layer and at intervals in the display area A-A. For example, in the display area A-A, each touch trace 15 may be disposed between two adjacent data traces 14. The touch traces 15 are respectively and correspondingly connected to the touch electrodes 120 and the touch pins 131. It should be noted that, each touch trace 15 is correspondingly connected to one touch electrode 120 and one touch pin 131, so as to accurately sense the touched position of the touch electrode 120. All touch traces 15 do not intersect with all data traces 14 projected onto the non-display area B-B. For example, the touch trace 15 may be connected to the touch pin 131 by providing a winding structure. By setting the touch running line 15 and the data running line 14 not to cross in the non-display area B-B, for example, the connection between the touch running line 15 and the touch pin 131 can be realized through a winding structure, no through holes are required to be formed or the number of the through holes can be reduced, and the problem of reduced connection reliability of the touch running line and the driving chip caused by the cross line of the through holes is avoided. In addition, the arrangement of the non-display area B-B via holes is reduced or eliminated, so that the space of the non-display area B-B of the display panel 10 can be saved, and convenience is brought to the realization of a narrow frame. In addition, the length of the winding structure of the touch trace 15 in the non-display area B-B is much smaller than that of the touch trace 15 in the display area A-A, so that the winding structure basically does not increase the voltage drop problem of the touch trace 15, thereby improving the reliability of connection between the touch trace 15 and the driving chip 13.
It should be noted that, in the manufacturing process of the display panel 10, different materials such as a metal layer and an insulating layer are disposed layer by layer to manufacture the display panel. For the bottom gate thin film transistor, a first metal layer may be prepared as a gate electrode of the thin film transistor, and a second metal layer may be disposed as a source electrode and a drain electrode of the thin film transistor after an insulating layer is laid. Then, an insulating layer and two conductive layers are provided as the touch layer 12 and the pixel layer 11, respectively. It will be appreciated that the above-mentioned layer structure is generally disposed in the display area A-A, and the structure of the non-display area B-B is fabricated together with the display area A-A, so that the non-display area B-B is also generally a laminated structure, including two metal layers, and two metal layers may be selected for the data pins 130 and the touch pins 131 of the driving chip 13 to be disposed. For example, all the data pins 130 and all the touch pins 131 may be set to the same layer, i.e., the first metal layer is selected or the second metal layer is selected to fabricate the data pins 130 and the touch pins 131. Of course, all the data pins 130 and all the touch pins 131 may be layered, that is, one of the nc pins 130 and the touch pins 131 is made of a first metal layer, and the other of the nc pins 130 and the touch pins 131 is made of a second metal layer.
For the arrangement of the data pins 130 and the touch pins 131 in the same layer or in different layers, the embodiment of the application can realize the scheme of avoiding the overline through a winding structure. The following will explain separately.
In the first case, i.e., the case shown in fig. 4, the plurality of touch pins 131 and the plurality of data pins 130 are arranged in the same layer. For example, the plurality of data pins 130 may be divided into a plurality of data pin groups 132, and the plurality of touch pins 131 may be divided into a plurality of touch pin groups 133. Each set of touch pins 133 is disposed between two adjacent sets of data pins 132. Each data pin group 132 may include adjacent first and second data pins 130a and 130b. The first data pins 130a and the second data pins 130b are disposed in two adjacent rows, and the projection of the second data pins 130b on the first data pins 130a is not overlapped with the first data pins 130 a. Each touch pin group 133 may include a first touch pin 131a and a second touch pin 131b. The first touch pins 131a are adjacent to and arranged in the same row as the first data pins 130a, the second touch pins 131b are adjacent to and arranged in the same row as the second data pins 130b, and the projection of the second touch pins 131b on the first touch pins 131a is not overlapped with the first touch pins 131 a. It will be appreciated that the first data pin 130a and the first touch pin 131a are adjacent to each other and are arranged in the same row at intervals, the second data pin 130b and the second touch pin 131b are adjacent to each other and are arranged in another row at intervals, and the second data pin 130b and the second touch pin 131b are empty or are arranged in a staggered manner.
The plurality of touch traces 15 may include a first touch trace 15a, where the first touch trace 15a is disposed between two adjacent data traces 14 in the display area A-A. The first touch trace 15a is disposed between the first data pin 130a and the second data pin 130B in the non-display area B-B, is disposed around the second data pin 130B, and is connected to the first touch pin 131 a. It will be appreciated that the first touch trace 15a bypasses the first data pin 130a and the second data pin 130b to connect with the first touch pin 131a, rather than connecting by way of opening a via hole and transversely crossing the line, so that the problem of unreliable connection caused by corrosion of the via hole can be reduced.
The first touch trace 15a may include a first bending section 151, a second bending section 152, and a third bending section 153 connected in sequence. At least a portion of the first bending section 151 is disposed in the non-display area B-B, and the second bending section 152 is disposed at one side of the first data pin 130 a. The third bending section 153 is disposed around the second data pin 130b, and an end of the third bending section 153 away from the second bending section 152 is connected to the first touch pin 131 a. The sum of the lengths of the second bending section 152 and the third bending section 153 is smaller than the length of the first touch trace 15a in the display area A-A. It can be appreciated that, since the area of the display area A-A of the display panel 10 is much larger than that of the non-display area B-B, the length of the first touch trace 15a in the display area A-A is much longer than that of the first touch trace 15a in the non-display area B-B. In this way, although the first touch trace 15a is provided with the winding structure in the non-display area B-B to increase the length of the first touch trace 15a in the non-display area B-B, the length of the winding structure is much smaller than the length of the first touch trace 15a in the display area A-A, so that the part of the winding structure does not cause excessive voltage drop. Therefore, the arrangement of the winding structure can increase the reliability of the connection between the non-display area B-B touch trace 15 and the touch pin.
In an exemplary embodiment, the first touch pin 131a may include a first side facing the display area A-A and a second side opposite to the first side, and the first touch trace 15a bypasses the second data pin 130b and is connected to the second side of the first touch pin 131 a.
For each group of touch pins 133, the connection between the first touch pin 131a and the first touch trace 15a and the connection between the second touch pin 131b and the other touch trace 15 are different. For example, the plurality of touch traces 15 may further include a second touch trace 15b, where the second touch trace 15b is adjacent to and spaced apart from the first touch trace 15 a. The second touch pin 131B may include a first side facing the display area A-A and a second side opposite to the first side, and the second touch trace 15B is connected to the first side of the second touch pin 131B in the non-display area B-B. It is understood that the connection between the second touch trace 15b and the second touch pin 131b does not need a winding structure, which is determined by the positional relationship between the touch pin 131 and the data pin 130. Therefore, the length of the second touch trace 15B in the non-display area B-B is smaller than that of the first touch trace 15a in the non-display area B-B.
Illustratively, the first data pin 130a includes a first side facing the display area A-A and a second side opposite the first side. The second data pin 130b also includes a first side facing the display area A-A and a second side opposite the first side. The plurality of data traces 14 includes adjacent first data traces 14a and second data traces 14b, the first data traces 14a being connected to a first side of the first data pin 130a and the second data traces 14b being connected to a first side of the second data pin 130b. It should be noted that, in this case, only the first touch trace 15a needs to be wound, and compared with the manner of winding the first touch trace 15a, the second touch trace 15b, the first data trace 14a and the second data trace 14b, the winding of the first touch trace 15a is simpler and more convenient.
It should be noted that, in the embodiment of the present application, the arrangement of the touch trace 15 and the data trace 14 in the non-display area B-B is not limited to the above-mentioned manner of winding the first touch trace 15 a.
For example, please refer to fig. 1-4 in combination with fig. 5, fig. 5 is a third structural schematic diagram of the display panel in the display device shown in fig. 1. The first touch trace 15a may be replaced by a first data trace 14a, that is, the first data trace 14a is disposed between the first touch pin 131a and the second touch pin 131B in the non-display area B-B and connected to the first data pin 130 a. It will be appreciated that in this manner, the first data trace 14a is routed, and the first data trace 14a bypasses the second touch pin 131b and is connected to the second side of the first data pin 130 a. The first touch trace 15a is connected to a first side of the first touch pin 131a, the second touch trace 15b is connected to a first side of the second touch pin 131b, and the second data trace 14b is connected to a first side of the second data pin 130b. Likewise, by setting the touch trace 15 and the data trace 14 not to cross in the non-display area B-B, for example, connection between the touch trace 15 and the touch pin 131 can be realized through a winding structure, no via holes are required to be formed or the number of via holes can be reduced, so that the problem of reduced connection reliability between the touch trace and the driving chip caused by via hole line crossing is avoided. In addition, the arrangement of the non-display area B-B via holes is reduced or eliminated, so that the space of the non-display area B-B of the display panel 10 can be saved, and convenience is brought to the realization of a narrow frame.
In the second case, please refer to fig. 1-5 and fig. 6, fig. 6 is a fourth structural diagram of the display panel in the display device shown in fig. 1. The plurality of touch pins 131 and the plurality of data pins 130 are arranged in layers. For example, the plurality of touch pins 131 may be fabricated using a first metal layer, and the plurality of data pins 130 may be fabricated using a second metal layer. In this case, the plurality of touch pins 131 and the plurality of data pins 130 may also be divided into a plurality of touch pin groups 133 and a plurality of data pin groups 132, respectively. The arrangement of each touch pin group 133 and each data pin group 132 is the same as that in the first case, except that the plurality of touch pins 131 and the plurality of data pins 130 are different layers. Therefore, reference may be made to the description of the first case, and the description is not repeated here.
Since the touch trace 15 and the touch pin 131 are disposed on different layers, the layer where the first data pin 130a is disposed may be provided with the first via hole 16a, so that the first touch trace 15a passes through the first via hole 16a and bypasses the projection of the second data pin 130b on the first touch pin 131a to connect with the first touch pin 131 a. It should be noted that, although the first via hole 16a is provided, in the embodiment of the present application, the connection between the touch trace 15 and the touch pin 131 is still realized by a winding manner, so that the problem of unreliable connection caused by via hole line crossing can be reduced.
The second touch trace 15b is disposed adjacent to and spaced apart from the first touch trace 15a in the display area A-A. The layer of the first data pin 130a is further provided with a second via hole 16b, so that the second touch trace 15b penetrates through the second via hole 16b and is connected with the second touch pin 131b.
In the first case, the first data trace 14a may be used to replace the first touch trace 15a to implement the winding structure, which is not described herein.
Exemplary, the embodiment of the present application further provides a display panel 10, and the structural composition of the display panel 10 may refer to fig. 1 to 6 and the above description, which are not repeated here. The difference between the embodiment of the present application and the above-mentioned fig. 1 to 6 is that at least one touch trace 15 bypasses the data trace 14 and the data pin 130 in the non-display area B-B and is connected to the touch pin 131, so that the touch trace 15 does not cross the data trace 14. That is, one of the plurality of touch traces 15 may have a winding structure, and the rest of the touch traces 15 may be arranged across the wires. Two, three or all of the touch traces 15 may have a winding structure, and the touch traces may be selected according to needs, which is not limited herein, so long as a scheme of reducing the arrangement of the via-crossing structure is implemented, thereby reducing the problem of unreliable connection caused by corrosion of the via.
In the display panel 10 and the display device 1 provided in the embodiments of the present application, the touch trace 15 and the data trace 14 are set to be non-intersecting in the non-display area B-B, for example, the connection between the touch trace 15 and the touch pin 131 can be realized through a wire winding structure, no via holes need to be formed or the number of via holes can be reduced, so that the problem of reduced connection reliability between the touch trace and the driving chip caused by via hole line crossing is avoided. In addition, the arrangement of the non-display area B-B via holes is reduced or eliminated, so that the space of the non-display area B-B of the display panel 10 can be saved, and convenience is brought to the realization of a narrow frame.
