It should be noted that, in case of conflict, different features in the embodiments of the present application may be combined with each other.
Before the technical scheme of the application is introduced, the structures of some existing common touch display screens are simply introduced.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a partial film structure of a touch display screen. As shown in the figure, the touch display screen 1 'may include a touch module 11', a display panel 12 ', a first Flexible Printed Circuit (FPC) 14', a second Flexible Printed Circuit 15 ', and a chip 16'. The touch module 11 ' may include a touch substrate 111 ' on one side of the display panel 12 ' and a touch functional layer 112 ' on one side of the touch substrate 111 ' away from the display panel 12 ', and the touch module 11 ' and the display panel 12 ' are encapsulated by an encapsulating material 13 '.
The touch function layer 112 ' includes a touch pattern (not shown) formed by touch electrodes and touch pins (not shown), and the touch pins are connected to bonding pins 113 ' on the touch module 11 ' through conductive leads. The bonding pins 113 'of the touch module 11' are bonded to the bonding pins 141 'of the first flexible circuit board 14', so as to electrically connect the touch module 11 'and the first flexible circuit board 14'. The bonding pins 142 ' of the first flexible circuit board 14 ' are bonded to the bonding pins 152 ' of the second flexible circuit board 15 ' to electrically connect the first flexible circuit board 14 ' and the second flexible circuit board 15 ', so as to establish a signal path between the chip 16 ' on the second flexible circuit board 15 ' and the touch module 11 '.
Display driving wires (not shown in the figure) on the display panel 12 ' are connected to the bonding pins 121 ', and the display panel 12 ' is electrically connected to the second flexible circuit board 15 ' through bonding between the bonding pins 121 ' and the bonding pins 151 ', so as to establish a signal path between the chip 16 ' on the second flexible circuit board 15 ' and the display panel 12 '.
In the above structure, three times of bonding is required, which increases the production cost of the touch display screen 10'. Meanwhile, the touch display screen 10' manufactured by the method is thick and cannot be thinned further, so that the market competitiveness of the product is reduced.
Further, referring to fig. 2, fig. 2 shows a partial film structure diagram of another touch display screen, as shown in the figure, the touch display screen 2 ' may include a touch module 21 ', a display panel 22 ', a flexible circuit board 25 ' and a chip 26 '. The touch module 21 'may include a touch substrate 211' on one side of the display panel 22 'and a touch function layer 212' on one side of the touch substrate 211 'close to the display panel 22'. The touch module 21 ' and the display panel 22 ' are encapsulated by the encapsulating material 23 '.
The touch functional layer 212 ' may include a touch pattern (not shown) and a touch pin (not shown) formed by a touch electrode, and the touch module 21 ' forms a protrusion structure and contacts with a corresponding protrusion structure 221 ' on the display panel 220 ' through the electrical contact surface 212a ', so as to establish a signal channel between the touch module 21 ' and the display panel 22 '. The display panel 22 'establishes a signal path between the touch module 21' and the chip 26 'on the flexible circuit board 25' through bonding between the bonding pins 222 'and the bonding pins 251'.
The touch display screen 2 'shown in fig. 2 has a small number of bonding times, and only one flexible circuit board is needed, so that the defects in the touch display screen 1' shown in fig. 1 can be overcome. However, the touch display screen 2' shown in fig. 2 has a phenomenon of poor touch or touch failure in actual use. The inventor analyzes and discovers that a large number of touch display screens 2' with the phenomenon is basically caused by the interference of the touch signals by external signals. Meanwhile, the inventor also finds that the more serious the attenuation of the touch signal in the transmission process, the more the touch signal is interfered by an external signal, the attenuation degree of the touch signal in the transmission process is related to the impedance on the transmission route of the touch signal, and the greater the impedance is, the more obvious the attenuation is.
The inventor further finds that in the touch display screen 2 ' shown in fig. 2, the touch pins are distributed on the bump structure of the touch module 21 ', please refer to fig. 3, fig. 3 shows a touch pin distribution diagram on the electrical contact surface 212a ' of the bump structure shown in fig. 2, as shown in the figure, the touch pins 2121 ' are distributed on the electrical connection surface 212a ' at intervals, and due to the limitation of the size of the bump structure, the touch pins 2121 ' on the electrical connection surface 212a ' are very thin, which makes the electrical contact area between the touch pins 2121 ' and the conductive pins on the corresponding bump structure 221 ' small, which increases the impedance of the transmission route of the touch signal and increases the interference of the external signal to the touch signal.
In order to solve the above technical problems, the inventor innovatively designs the following technical scheme that the impedance of a touch signal transmission line can be reduced by making the touch pins and the conductive pins have a large electrical contact area. Specific implementations of the present application will be described in detail below with reference to the accompanying drawings.
First embodiment
Referring to fig. 4, fig. 4 is a schematic diagram illustrating a film layer structure of a touch display screen 2 according to a first embodiment of the present disclosure.
The touch display screen 2 provided in this embodiment may include a touch module 21 and a display panel 22, and the touch module 21 may include a touch substrate 211 and a touch functional layer 212.
The touch function layer 212 is located on one side of the touch substrate 211 close to the display panel 22. Referring to fig. 5, the touch functional layer 212 may include a touch pattern 210 formed by touch electrodes 2122, and touch pins 2121 correspondingly connected to the touch electrodes 2122, wherein the touch pins 2121 are distributed in the wiring region 220 around the touch pattern 210, and the touch pins 2121 and the touch electrodes 2122 are connected by conductive leads 2123.
The display panel 22 is provided with conductive pins 221 corresponding to the touch pins 2121 on a side thereof close to the touch substrate 211.
The display panel 22 and the touch module 21 are packaged by the packaging material 23, and the touch pins 2121 are electrically connected to the conductive pins 221.
In the above structure, the touch pins 2121 are distributed in the wiring region 220 around the touch pattern 210, so that the touch pins 2121 have a larger installation space, and the touch pins 2121 and the conductive pins 221 have a larger electrical contact area, thereby reducing the impedance of a transmission line of a touch signal and reducing the influence of an interference signal on the touch signal.
Referring to fig. 4 again, the touch display screen 2 may further include a flexible circuit board 24 and a chip 25 disposed on the flexible circuit board 24, and the flexible circuit board 24 is bonded to the display panel 22 through a bonding pin 241 and a bonding pin 222 disposed on the display panel 22, so as to achieve connection between the flexible circuit board 24 and the display panel 22. In this embodiment, the chip 25 may be a Touch and Display Driver integrated chip (TDDI IC) integrating Touch and Display functions, and the chip 240 may also be two independent chips respectively providing Touch signals and Display driving signals.
Referring to fig. 5 and fig. 6, in a possible implementation manner of the embodiment of the present disclosure, each touch electrode 2122 may be correspondingly configured with two touch pins 2121, and the two touch pins 2121 may be respectively located at two sides of the touch electrode 2122. In this embodiment, taking the touch electrode X5 shown in fig. 6 as an example, the touch pins 2121 corresponding to the touch electrode X5 can be Pad-X51 and Pad-X52, respectively, and the touch pins Pad-X51 and Pad-X52 are disposed on two sides of the touch electrode X5. In addition, in order to standardize the layout position of each touch pin 2121 and simplify the wiring layout between the touch pin 2121 and the touch electrode 2122, the touch pin 2121 and the touch electrode 2122 may be disposed nearby. Alternatively, the touch pins Pad-X51 and Pad-X52 can be disposed in the wiring area 220 corresponding to the area between the touch electrode X4 and the touch electrode X6.
Referring to fig. 7, in another possible implementation manner of the embodiment of the present application, each touch electrode 2122 may be configured with one touch pin 2121, the touch pin 2121 is located at one side of the touch electrode 2122, and the touch pins 2121 of two adjacent touch electrodes 2122 are located at different sides, so that the arrangement space of the touch pins 2121 can be increased. Taking the touch electrode X5 and the touch electrode X6 in fig. 7 as an example, the touch pin 2121 corresponding to the touch electrode X5 is Pad-X5, and the touch pin 2121 corresponding to the touch electrode X6 is Pad-X6, where Pad-X5 may be located on the upper side of the touch electrode X5, and Pad-X6 may be located on the lower side of the touch electrode X6. In order to simplify the wiring layout of the touch pins 2121 and the touch electrodes 2122, the touch pins 2121 and the touch electrodes 2122 are disposed nearby. Alternatively, the touch pins Pad-X5 may be disposed in the wiring area 220 corresponding to the area between the touch electrode X4 and the touch electrode X6, and the touch pins Pad-X6 may be disposed in the wiring area 220 corresponding to the area between the touch electrode X5 and the touch electrode X7.
Further, in the embodiment of the present application, referring to fig. 8, the touch pins 2121 may be located in an extending direction of the touch electrode 2122 connected to the touch pins 2121. Thus, when the touch functional layer 212 is manufactured, only the touch electrode 2122 needs to be extended appropriately, so that the touch electrode 2122 is directly connected to the touch pin 2121, and the conductive lead 2123 connecting the touch electrode 2122 and the touch pin 2121 does not need to be manufactured, which can reduce the manufacturing process of the touch functional layer 212.
The shapes of the touch electrode 2122 and the touch pattern 210 shown in fig. 5-8 are only an example for explaining the technical solution provided in the embodiments of the present application, and it should not be understood that the technical solution of the present application is only applicable to the structure shown in the above schematic diagram, and in other embodiments of the present application, the shapes of the touch electrode 2122 and the touch pattern 210 may be modified.
