Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device provided in the prior art. As shown in fig. 1, in the display device provided in the related art, the display panel includes a display area and a non-display area disposed adjacent to the display area. The non-display area comprises a binding area, the binding area is provided with a plurality of first pad groups and second pad groups, the first pad groups are bound with driving chips, the second pad groups are bound with flexible circuit boards, and the flexible circuit boards and the driving chips are rectangular.
The first bonding pad group comprises a driving chip input bonding pad and a driving chip output bonding pad, the driving chip output bonding pad is located on one side, close to the display area, of the driving chip input bonding pad, the driving chip input bonding pad is sequentially arranged in a first direction to form a straight line, the driving chip output bonding pad is sequentially arranged in the first direction to form a straight line, and the first direction is perpendicular to the direction from the display area to the binding area.
Wherein, the non-display area is also provided with a fan-shaped wiring in a zigzag shape. The fan-shaped wiring comprises a first section and a second section which are connected with each other, the first section is vertical to the first direction, and the second section is inclined. And the farther away from the display panel bezel, the longer the length of the first segment.
It should be noted that, since the space of the first segment of the fan-shaped trace is not utilized, the second pad group required for binding the flexible circuit board of the display panel and the first pad group required for binding the driver chip need to move downward, which is not favorable for the narrow frame design of the display device.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a display device according to a first implementation manner of the present application. As shown in fig. 2, the display device 10 provided in the embodiment of the present application includes a display area 10a and a non-display area 10b disposed adjacent to the display area 10 a. The non-display area 10b includes a sector 10c and a binding area 10d disposed adjacent to the sector 10 c.
Wherein the bonding region 10d is provided with the first pad group 101. The first pad group is bound with a driver chip 102, and the driver chip 102 is in a zigzag shape.
The first pad group 101 includes a driver chip input pad 1011 and a driver chip output pad 1012. The driver chip output pads 1012 are located on a side of the driver chip input pads 1011 close to the display area 10a, and the driver chip input pads 1011 are sequentially arranged in a zigzag shape along the first direction X, and the driver chip output pads 1012 are sequentially arranged in a zigzag shape along the first direction X. The first direction X is perpendicular to the direction of the display area 10a to the binding area 10 d.
It should be noted that, for the first reason, since the driving chip output pads 1012 are sequentially arranged in a zigzag shape along the first direction X, the length of the straight line segment of the fan-shaped trace can be reduced, so that the space of the straight line segment of the fan-shaped trace can be utilized, the overall length of the driving chip and the fan-shaped trace in the first direction can be further shortened, the reduction of the frame of the display device is facilitated, and the realization of the narrow frame of the display device is facilitated.
Second, the driver chip output pads 1012 are sequentially arranged in a zigzag shape along the first direction X, and the driver chip input pads 1011 are sequentially arranged in a zigzag shape along the first direction X, so that the driver chip 102 can be in a zigzag shape. Therefore, the driving chip 102 can form a space for placing other components on the side far away from the display area 10a, which further helps to reduce the frame of the display device and helps to realize a narrow frame of the display device.
It should be noted that the display area 10a includes a plurality of signal lines extending vertically and arranged horizontally. Optionally, the signal line may be one or both of a data line and a touch signal line.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a display device according to a second implementation manner of the present application. As shown in fig. 3, in the display device 10 provided in the embodiment of the present application, the display device 10 further includes fan-shaped traces 103. The fan-shaped trace 103 is located on one side of the driving chip output pad 1012 close to the display area 10 a.
It should be noted that the sector trace 103 provided in the embodiment of the present application is in a zigzag shape. The fan-shaped trace 103 includes a first section and a second section connected to each other, the first section is perpendicular to the first direction, and the second section is inclined. Because drive chip output pad 1012 is zigzag, consequently, fan-shaped first section of walking line 103 all can not be too long to can reduce the shared space of fan-shaped first section of walking line 103, and then can shorten drive chip and fan-shaped whole length of walking line on the first direction, help reducing display device's frame, help the realization of display device narrow frame.
It should be noted that the sector trace 103 is used for inputting a data signal into the display panel, so one end of the sector trace 103 is connected to the driving chip output pad 1012, and the other end of the sector trace 103 is connected to a signal line in the display area 10 a. The sector trace 103, the driver chip output pad 1012, and the signal lines in the display area 10a are all in a one-to-one correspondence relationship.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a third implementation manner of a display device according to an embodiment of the present disclosure. As shown in fig. 4, in the display device 10 provided in the embodiment of the present application, the driver chip input pads 1011 include at least two first oblique segments connected in sequence, and the first oblique segments are composed of at least three driver chip input pads 1011 arranged in sequence. The driving chip output pads 1012 include at least two second oblique segments connected in sequence, and the second oblique segments are composed of at least three driving chip output pads 1012 arranged in sequence.
In the same first inclined segment, an included angle formed by a connecting line of the first driver chip input pad 1011 and the last driver chip input pad 1011 and the first direction is defined as a first included angle a1, and the first included angle a1 is greater than 30 degrees and less than 80 degrees. The first included angle a1 is 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, or 80 degrees. The particular value of first included angle a1 is determined by the particular requirements of the use of display device 10.
In the same second inclined segment, an included angle formed by a connecting line of the first driver chip output pad 1012 and the last driver chip output pad 1012 and the first direction is defined as a second included angle a2, and the second included angle a2 is greater than 30 degrees and less than 80 degrees. The second included angle a2 is 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, or 80 degrees. The particular value of second included angle a2 is determined by the particular requirements of the use of display device 10.
It should be noted that the first included angle a1 and the second included angle a2 cannot be too large or too small. When the first included angle a1 and the second included angle a2 are too large, the length of the first segment of the fan-shaped trace 103 is too long, and the space of the first segment of the fan-shaped trace 103 is utilized less, which is not favorable for realizing the narrow frame of the display device 10. In addition, when the first included angle a1 and the second included angle a2 are too small, the length of the space formed by the driving chip 102 on the side far away from the display area 10a along the first direction X is small, which is not favorable for placing other components and is not favorable for realizing a narrow frame of the display device 10. Therefore, the display device 10 provided in the embodiment of the present application not only can make full use of the first space of the sector trace 103 by defining the first included angle a1 and the second included angle a2 to be greater than 30 degrees and less than 80 degrees, but also is convenient for placing other components in the space formed by the driving chip 102 on the side far away from the display area 10a, thereby facilitating the implementation of the narrow frame of the display device 10.
Referring to fig. 5, fig. 5 is a first structural schematic diagram of a fourth implementation manner of a display device according to an embodiment of the present application. As shown in fig. 5, in the display device 10 provided in the embodiment of the present application, the driving chip output pad 1012 includes a first driving chip output pad 1012a and a second driving chip output pad 1012 b. The first driver chip output pads 1012a and the second driver chip output pads 1012b are arranged in a zigzag shape along the first direction X, and the first driver chip output pads 1012a are located on one side of the second driver chip output pads 1012b close to the display area 10 a.
Among them, the fan-shaped traces 103 are complicated in wiring, that is, the distance between adjacent fan-shaped traces 103 is small. The fan-shaped traces 103 are disposed in a one-to-one correspondence with the driver chip output pads 1012. Therefore, the embodiment of the present application divides the driving chip output pads 1012 into two rows, and specifically, divides the driving chip output pads 1012 into the first driving chip output pads 1012a and the second driving chip output pads 1012b, and arranges them into one row, respectively.
It should be noted that the driving chip output pads 1012 of the embodiment of the present application are divided into two rows, which is not only beneficial to the arrangement of the wiring connection of the fan-shaped traces 103, and prevents the phenomenon of cross trace at the connection between the driving chip output pads 1012 and the fan-shaped traces 103, but also can avoid the phenomenon of signal interference when the driving chip output pads 1012 transmit signals to the fan-shaped traces 103.
Please refer to fig. 6. Fig. 6 is a second structural diagram of a fourth implementation of a display device according to an example of the present application. As shown in fig. 6, in the display device 10 provided in the embodiment of the present application, the first driver chip output pad 1012a and the second driver chip output pad 1012b are disposed in a staggered manner.
It should be noted that both the first driver chip output pad 1012a and the second driver chip output pad 1012b need to be connected to the fan-shaped trace 103. Therefore, if the first driver chip output pad 1012a and the second driver chip output pad 1012b are disposed opposite to each other, a phenomenon that a connection between the first driver chip output pad 1012a and the sector trace 103 crosses a connection between the second driver chip output pad 1012b and the sector trace 103 may occur, so that signals transmitted by the sector trace 103 may be interfered. Therefore, in the embodiment of the present application, the first driver chip output pad 1012a and the second driver chip output pad 1012b are disposed in a staggered manner, so that the above phenomenon can be avoided. Of course, the driver chip output pads 1012 may also be arranged in multiple rows, and the multiple rows of driver chip output pads 1012 are all arranged in a staggered manner. Similarly, the driver chip input pads 1011 may be arranged in a plurality of rows, and the driver chip input pads 1011 in the plurality of rows may be arranged in a staggered manner.
Referring to fig. 7, fig. 7 is a first structural diagram of a display device according to a fifth implementation manner of the embodiment of the present application. As shown in fig. 7, in the display device 10 provided in the embodiment of the present application, the non-display area 10b is further provided with a plurality of second pad groups 104, the flexible circuit boards 105 are respectively bound to the second pad groups 104, and the flexible circuit boards 105 are located on a side of the driver chip 102 away from the display area 10 a.
It should be noted that the driving chip 102 requires the flexible circuit board 105 to provide signals, and therefore the flexible circuit board 105 needs to be provided. And the flexible circuit board 105 needs to be connected to the GOA circuits located on the left and right frames of the display device 10, therefore, the flexible circuit board 105 needs to be located on the side of the driver chip 102 away from the display area 10 a.
In addition, the side of the flexible circuit board 105 away from the display area 10a needs to be farther away from the display area 10a than the side of the driver chip 102 away from the display area 10 a. So that the flexible circuit board 105 can reserve a part of the space for connecting the GOA circuits located on the left and right frames of the display device 10.
Referring to fig. 8, fig. 8 is a second structural schematic diagram of a display device according to a fifth implementation manner of the present application. As shown in fig. 8, in the display device 10 provided in the embodiment of the present application, two sides of the driving chip 102 away from the display area 10a are bent to form a groove 106. The flexible circuit board 105 is disposed in the recess 106.
Among them, it should be noted that, since the space of the groove 106 is large enough to accommodate the flexible circuit board 105. Therefore, by disposing the flexible circuit board 105 in the groove 106, the distance between the driving chip 102 and the flexible circuit board 105 in the first direction X can be shortened, thereby facilitating the implementation of a narrow bezel of the display device 10.
Referring to fig. 9, fig. 9 is a third structural schematic diagram of a display panel according to a fifth implementation manner of the embodiment of the present application. As shown in fig. 9, in the display device 10 provided in the embodiment of the present application, the second pad group 104 includes flexible circuit board pads 107, and the flexible circuit board pads 107 are sequentially arranged along the first direction X to form a zigzag shape.
It should be noted that, the flexible circuit board pads 107 need to be arranged in one-to-one correspondence with the driver chip input pads 1011, and the driver chip input pads 1011 are sequentially arranged along the first direction X to form a zigzag shape. Therefore, the flexible circuit board pads 107 are arranged in the first direction X in a zigzag manner, which not only shortens the length of the connection line connecting the flexible circuit board pads 107 and the driver chip input pads 1011, but also facilitates reducing the cost of the display device 10.
In addition, the flexible circuit board pads 107 are sequentially arranged in a zigzag shape along the first direction X, so that the flexible circuit board 105 can be arranged in a zigzag shape, the distance between the driving chip 102 and the flexible circuit board 105 in the first direction X can be reduced, a space for placing other structures is formed on one side of the flexible circuit board 105 away from the display area 10a, and the realization of the narrow frame of the display device 10 is facilitated.
Referring to fig. 10, fig. 10 is a schematic structural diagram of a display panel according to a sixth implementation manner of the present application. As shown in fig. 10, in the display device 10 provided in the embodiment of the present application, the number of driver chip output pads 1012 is greater than the number of driver chip input pads 1011.
It should be noted that, since the number of the fan-shaped traces 103 is much greater than the number of the pads 107 of the flexible circuit board, the number of the driver chip output pads 1012 is much greater than the number of the driver chip input pads 1011. Therefore, the number of driver chip output pads 1012 is made larger than the number of driver chip input pads 1011, and the cost of the display device 10 can be reduced.
