Detailed Description
Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Referring to fig. 1, the present invention provides a display panel, including: a display area AA and a non-display area BB positioned at the periphery of the display area AA; the display area AA includes a plurality of scan lines G extending in the first direction x; the non-display area BB includes two first driving units 10 and at least one second driving unit 20, the two first driving units 10 being located at opposite sides of the display area AA; wherein, the first driving unit 10 is disposed opposite to the display area AA in a first direction x, and the second driving unit 20 is disposed opposite to the display area AA in a second direction y, the first direction x intersecting the second direction y;
the first driving unit 10 includes a plurality of first shift registers 11, and an output terminal of each first shift register 11 is electrically connected to at least one scan line G; the second driving unit 20 includes a plurality of second shift registers 21, and an output terminal of each second shift register 21 is electrically connected to at least one scan line G through a connection line L;
in the first direction x, the length of the display panel 100 is d 1; in the second direction y, the length of the display panel 100 is d 2; wherein d1 is greater than d 2.
In this embodiment, the length of the display panel 100 in the first direction x is greater than the length of the display panel 100 in the second direction y, so that the display panel 100 has a wide-screen display function, at this time, the length of the scan line G extending along the first direction x is longer, and although the first shift register 11 can perform bilateral driving on the scan line G, that is, scan signals are input at both ends of the scan line G, the closer to the midpoint of the scan line G, the closer the scan signal is, the weaker the scan signal is.
Of course, the first shift register 11 may also perform staggered driving on the scan lines G, that is, the output end of the first shift register 11 is electrically connected to the odd-numbered scan lines G in the first driving unit 10 located at one side of the display area AA; in the first driving unit 10 located at the other side of the display area AA, the output end of the first shift register 11 is electrically connected to the even scan lines G, but the signal strength of the scan signal on the scan lines G tends to be weakened along the transmission direction.
Due to the existence of the second driving unit 20, the strength of the scanning signal of the scanning line G, i.e., the driving capability, can be enhanced by the second shift register 21. The second driving unit 20 is disposed opposite to the display area AA in the second direction y, and the other side of the display area AA opposite to the second driving unit 20 is generally used for setting the binding area 30 to bind the driving chip or the flexible circuit board, so that the second driving unit 20 does not occupy the frame non-display area where the first driving unit 10 is located, and does not affect the line arrangement of the scanning line G. Referring to fig. 2, in the present embodiment, the first shift registers 11 of the first driving unit 10 are in a cascade relationship, and the output end of the first shift register 11 is electrically connected to at least one scan line G, so as to implement a scan driving function for each scan line G in the display area AA. Specifically, the signal input end of the first-stage first shift register 11 is configured to receive a start signal STV1, and from the second-stage first shift register 11, the signal input end of the next-stage first shift register 11 is electrically connected to the output end of the previous-stage first shift register 11, so as to output a scanning signal to the scanning line G step by step, and drive the display area AA to display an image.
Referring to fig. 3, in the present embodiment, the second shift registers 21 of the second driving unit 20 are also in a cascade relationship, and the output ends of the second shift registers 21 are electrically connected to at least one scan line G through a connection line L, so as to enhance the scanning driving capability of each scan line G in the display area AA. Specifically, the signal input end of the first-stage second shift register 21 is configured to receive a start signal STV2, and from the second-stage second shift register 21, the signal input end of the second shift register 21 in the next stage is electrically connected to the output end of the second shift register 21 in the previous stage, so as to output a scanning signal to the scanning line G step by step, thereby improving the driving capability of the scanning line G. The start signal STV2 may be the same as the start signal STV1, or may be different from the start signal STV1, which is not limited in this embodiment.
It should be noted that the scan signal may be a forward scan signal or a reverse scan signal, which is not limited in this embodiment. In addition, there may be a plurality of arrangement manners of the connection lines L, the first shift register 11 and the second shift register 21 may be electrically connected to one or even a plurality of scan lines G, which is not specifically limited in this embodiment, but in order to more intuitively illustrate the technical solution of this embodiment, only the first shift register 11 and the second shift register 21 are respectively electrically connected to one scan line G, and the connection lines L are electrically connected to the scan lines G one by one along the first direction x in fig. 2 and 3.
The circuit structure of the first shift register 11 and the second shift register 21 can be seen from fig. 4, and includes transistors T1-T9 and capacitors C1-C2, where the transistor T is a P-type transistor having the functions of turning on at a low level and turning off at a high level; of course, the line structure of the shift register may be other, and this embodiment does not specifically limit this.
The following description refers to a high level signal as 1 and a low level signal as 0, wherein 1 and 0 represent logic levels thereof, which are provided only for better explaining the operation of the shift register provided in the present embodiment, and are not applied to the gate of each transistor T in specific implementation.
IN the stage T1, XCK is 1, CK is 0, and IN is 0, so that the transistor T1 is turned off, the rest of the transistors T are turned on, and OUT is 1, that is, a low level is written, and a high level is output; IN stage T2, XCK is 0, CK is 1, and IN is 1, so that transistors T2, T3, T4, T6, and T8 are turned off, and the rest of transistors T are turned on, but a low potential of the N1 node may be maintained by a capacitor C2, and a low level is output, that is, OUT is 0; IN the stage T3, XCK is 1, CK is 0, and IN is 1, so that the transistors T1, T5, and T7 are turned off, and the rest of the transistors T are turned on, OUT is 1, that is, CK is low, and the node N2 is low, outputting high; IN stage T4, XCK is 0, CK is 1, and IN is 1, so that transistors T2, T3, T4, T5, and T7 are turned off, the remaining transistors T are turned on, OUT is 1, that is, XCK low level, the low level of the N2 node is maintained by a capacitor C1, a high level is output, and the N1 node is made high level by a transistor T8; IN the stage T5, XCK is 1, CK is 0, and IN is 1, so that the transistors T1, T5, and T7 are turned off, the rest of the transistors T are turned on, and OUT is 1, that is, the N1 node is set to high level by the transistor T4, and the N2 node is stabilized to low level, thereby reducing ripple.
The display panel provided by the embodiment can effectively improve the driving capability of the scanning line by arranging the second driving unit; the second driving unit is arranged opposite to the display area in the second direction, so that the second driving unit does not occupy a non-display area where the first driving unit is located, and the narrow frame of the display device is facilitated; meanwhile, the second shift register in the second driving unit is electrically connected with the scanning line through the connecting line, the connecting line cannot influence the line arrangement of the scanning line of the display panel, the process difficulty can be effectively reduced, and the production efficiency of the display device is improved. In addition, the length of the display panel in the first direction is larger than that of the display panel in the second direction, so that wide-screen display is facilitated, wiring of the second driving unit can be more flexible and convenient, and the application range is wider.
In some alternative embodiments, please refer to fig. 1 and fig. 6 in combination, the scan lines G and the connecting lines L are arranged in different layers. In this embodiment, the connection lines L and the scan lines G are not on the same film layer, so that the connection lines L need to be electrically connected to the corresponding scan lines G through the via holes 40, and the connection lines L may be patterned together with other film layers of the display panel 10 except the film layer on which the scan lines G are located, so as to improve the film layer utilization rate of the display panel 100 and reduce the process difficulty, and at this time, the plurality of connection lines L may all be located on the same film layer or may be dispersed in a plurality of film layers; of course, a film layer may also be added on the display panel 100 for patterning the connecting lines L, and the embodiment is not limited thereto.
In some alternative embodiments, please refer to fig. 7, the extending direction of the connecting line L intersects the first direction x; the connection line L includes a connection portion L1 and a dummy portion L2, one end of the connection portion L1 is electrically connected to the second shift register 21, and the other end of the connection portion L1 is electrically connected to the dummy portion L2.
In this embodiment, the extending direction of the connecting line L intersects with the first direction x, and in order to more intuitively illustrate the technical solution of this embodiment, only the extending direction of the connecting line L is perpendicular to the first direction x. On the one hand, the output terminal of the second shift register 21 transmits the scan driving signal to the scan line G through the connection portion L1; on the other hand, the length difference between the connection lines L is reduced by the dummy section L2, so that the load difference between the connection lines L is also reduced, that is, the connection lines L are load-compensated by the dummy section L2, thereby improving the display uniformity of the display panel 100.
It should be noted that the lengths of the connection lines L and the distribution of the connection lines L with different lengths may be adjusted according to actual situations, and this embodiment does not specifically limit this, for example, all the connection lines L may be divided into multiple groups, and the lengths of each group of connection lines L are the same, that is, the lengths of the connection portion L1 and the dummy portion L2 are the same, which is beneficial to reducing the difficulty of the patterning process of the connection lines L and improving the production efficiency of the display panel.
Optionally, as shown in fig. 8, the extending directions of the connecting lines L are the same, and the lengths of the connecting lines L are also the same. In this embodiment, the extending direction and the length of each connecting line L are the same, so that the loads of the connecting lines L also tend to be the same, that is, the shorter the length of the connecting portion L1 is, the longer the length of the dummy portion L2 required for compensation is, and accordingly, the display uniformity of the display panel 100 can be further improved. Of course, the length distribution of the connecting lines L may be adjusted according to actual situations, and this embodiment does not specifically limit this.
In some alternative embodiments, please refer to fig. 9, the number of the second shift registers 21 in the second driving unit 20 is the same as the number of the scan lines G. Therefore, the output end of one second shift register 21 can be electrically connected with only one scanning line G, that is, the second shift register 21 and the scanning line G are in one-to-one connection relationship, so that the scanning signal on each scanning line G can be enhanced through the second shift register 21, and the driving capability of the second shift register can be improved.
In some alternative embodiments, please refer to fig. 10, the display panel 100 includes at least one bending region W and at least one non-bending region N, and the bending region W and the non-bending region N are adjacent to each other. Therefore, the display panel 100 can be bent along the bending area W to realize the folding function, and the folded display panel 100 is convenient to carry and can realize various display effects. The number of the bending regions W may be one or more according to practical situations, and the embodiment is not particularly limited thereto.
In this embodiment, the number of the second shift registers 21 in the second driving unit 20 may still be the same as the number of the scan lines G, and the second shift registers 21 may be arranged in the non-bending region N and connected to the scan lines G in a one-to-one manner, so as to avoid the bending operation from affecting the second shift registers 21, and effectively ensure the display effect of the display panel 100.
Optionally, as shown in fig. 11, there is one non-bending region N, and the second driving unit 20 is located in the non-bending region N. In this embodiment, the bending region W may be located in the non-display region BB, so that the operation of bending the display panel 100 along the bending region W does not affect the connection lines between the second shift registers 21 and the scan lines G in the second driving unit 20, and the display effect of the display panel 100 can be effectively ensured.
Optionally, referring to fig. 12, the number of the non-bending regions N is at least two, and at least one second driving unit 20 is disposed in at least one of the non-bending regions N. Specifically, the second driving unit 20 may be disposed in a part of the non-bending region N, or may be disposed in each non-bending region N; the number of the second driving units 20 may be one or more, so as to ensure that the driving capability of the scanning line G meets the requirement.
In this embodiment, since the second driving unit 20 is located in the non-bending region N, the operation of bending the display panel 100 along the bending region W will not affect the connection lines between the second shift registers 21 and the scan lines G in the second driving unit 20, and the display effect of the display panel 100 can be effectively ensured.
Optionally, as shown in fig. 13, in the first direction x, the length of the first non-bending region N1 is shorter, and the portion of the scan line G located in the first non-bending region N1 is correspondingly shorter, at this time, since the first non-bending region N1 is closer to the first driving unit 10 on one side thereof, the driving capability of the portion of the scan line G located in the first non-bending region N1 can be ensured to meet the requirement even without disposing the second driving unit 20 in the first non-bending region N1; the length of the second non-bending region N2 is longer, and the portion of the scan line G in the second non-bending region N2 is correspondingly shorter, so that the driving capability of the scan line G can be ensured to meet the requirement by increasing the number of the second driving units 20.
In some alternative embodiments, please refer to fig. 14, in the second driving unit 20, a size of at least one second shift register 21 is smaller than a size of the first shift register 11. In this embodiment, by setting the size of a certain number of second shift registers 21 to be smaller than the size of the first shift register 11, the arrangement of the second shift registers 21 in the non-display area BB can be performed under the condition that the number of the second driving units 20 is large, and the length of the non-display area BB in the second direction y is not increased, thereby being beneficial to realizing a narrow frame of the display device.
It should be noted that, although the size of a certain number of second shift registers 21 is designed to be smaller, the internal circuit structure of the second shift registers 21 may be the same as that of the larger second shift registers 21, and there are various ways to reduce the size of the second shift registers 21, which is not limited in this embodiment.
In some alternative embodiments, please refer to fig. 15, the length of the connection line L gradually increases from the central axis P of the display area AA to a direction approaching the first driving unit 10. That is, the closer the connecting lines L located on both sides of the central axis P are to the first shift register 11, the longer the connecting lines L are, so as to be beneficial to reducing the line load difference in the areas located on both sides of the central axis P and improve the display effect of the display panel 100.
In this embodiment, the arrangement of the connection lines L may be various, and fig. 15 only illustrates that the connection lines L located at two sides of the central axis P are connected with the odd-numbered scanning lines G and the even-numbered scanning lines G in an interlaced manner, but the present embodiment does not specifically limit this.
In some alternative embodiments, please refer to fig. 16, the output terminal of each second shift register 21 is electrically connected to at least two scan lines G through a connection line L. That is, one second shift register 21 may provide the scan signals for at least two scan lines G to improve the driving capability of the scan lines G. At this time, since the number of the second shift registers 21 is smaller than the number of the scanning lines G, the space occupied by the second driving unit 20 in the non-display area BB is reduced, which is advantageous for realizing a narrow frame of the display device.
In this embodiment, there are various ways in which each second shift register 21 is electrically connected to a scan line G through a connection line L, and this embodiment does not specifically limit this, and fig. 16 only illustrates that each second shift register 21 is electrically connected to two scan lines G through two connection lines L.
Alternatively, as shown in fig. 16, the output terminal of each first shift register 11 is electrically connected to at least two scan lines G. That is, one first shift register 11 can provide scanning signals for at least two scanning lines G, and since the number of the first shift registers 11 is less than that of the scanning lines G, it is beneficial to reduce the space occupied by the first driving unit 10 in the non-display area BB, so that a space can be provided for the arrangement of other lines, and it is also beneficial to implement the narrow frame of the display device.
Of course, a certain number of dummy shift registers may be added to the non-display area BB in fig. 16 to improve the stability of the scanning signal, so as to further improve the uniformity of the display panel 100, and both the position and the size of the dummy shift registers may be set according to actual needs, which is not limited in this embodiment specifically, for example, the dummy shift registers may be set opposite to the display area AA in the second direction y, and the size of the dummy shift registers is the same as the size of the second shift register 21.
The invention also provides a display device 200 comprising the display panel 100 provided by the invention.
Referring to fig. 17, a display device 200 of the present embodiment includes the display panel 100 according to any one of the above embodiments of the present invention. Fig. 17 illustrates the display device 200 by taking a tablet computer as an example.

by arranging the second driving unit, the driving capability of the scanning line can be effectively improved; the second driving unit is arranged opposite to the display area in the second direction, so that the second driving unit does not occupy a non-display area where the first driving unit is located, and the narrow frame of the display device is facilitated; meanwhile, the second shift register in the second driving unit is electrically connected with the scanning line through the connecting line, the connecting line cannot influence the line arrangement of the scanning line of the display panel, the process difficulty can be effectively reduced, and the production efficiency of the display device is improved.
