The technical contents of the present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of a display panel according to the present invention. As shown in fig. 1, in an embodiment of the present invention, the display panel includes: a first display area 1, a second display area 2, a first driving unit 3, a second driving unit 4, and a border area 5. The display panel may be a liquid crystal display panel or an organic light emitting display panel.
Specifically, the display panel includes a first display area 1 and a second display area 2 sequentially arranged in a first direction (X-axis direction in fig. 1). In the embodiment shown in fig. 1, the display panel comprises a plurality of first display areas 1 and a plurality of said second display areas 2. In fig. 1, a display panel having 4 first display regions and 4 second display regions is taken as an example for illustration, but the invention is not limited thereto. The number of the display areas can be adjusted according to the size or requirement of the display panel, which is not described herein.
As shown in fig. 1, the plurality of first display regions 1 and the plurality of second display regions 2 are alternately arranged in the first direction (X-axis direction in fig. 1). That is, the odd-numbered display regions (e.g., the first display region, the third display region) from left to right along the X-axis direction in fig. 1 are the first display region 1, and the even-numbered display regions (e.g., the second display region, the fourth display region) are the second display region 2. It should be noted that the first display area 1 and the second display area 2 in the embodiment of the invention refer to two adjacent display areas electrically connected to the driving units with different voltage levels, wherein the voltage levels of the driving units electrically connected to each of the first display areas or the second display areas may also be different. A border region 5 is included between each of the adjacent first and second display regions 1 and 2. In the present invention, the electrical connection means a mutual conductive connection.
Fig. 2 is a schematic structural diagram of a display panel according to the present invention. In order to show the structure of the display panel more clearly, fig. 2 illustrates a first display area and a second display area adjacent to each other in fig. 1 as an example.
As shown in fig. 2, the first display region 1 includes a plurality of first data lines 11 arranged in a first direction (X-axis direction in fig. 2) and extending in a second direction (Y-axis direction in fig. 2). The first driving unit 3 is electrically connected to the first display region 1 through a plurality of first data lines 11 in the first display region 1. Specifically, the first display region 1 may include a plurality of thin film transistors electrically connected to the first data lines 11 for driving the pixel electrodes in the first display region 1. The first driving unit 3 is electrically connected to the thin film transistor in the first display region 1 through the first data line 11, and then transmits a driving signal to the corresponding thin film transistor, so as to drive the first display region 1.
The second display region 2 includes a plurality of second data lines 21 arranged along the first direction (X-axis direction in fig. 2) and extending along the second direction (Y-axis direction in fig. 2), i.e., the extending direction and the arrangement direction of the second data lines 21 are the same as those of the first data lines 11. Similarly, the second driving unit 4 is electrically connected to the second display region 2 through a plurality of second data lines 21 in the second display region 2.
The border area 5 is located between the first display area 1 and the second display area 2. The boundary region 5 has at least one third data line 51 therein. The third data line 51 may be alternately electrically connected to the first driving unit 3 and the second driving unit 4. In the embodiment shown in fig. 2, the border area 5 has one third data line 51 therein. The term "alternately electrically connected" means that the third data line 51 is electrically connected to the first driving unit 3 in one display period and electrically connected to the second driving unit 4 in another display period, and the specific time period and manner of electrically connecting the first driving unit or the second driving unit can be referred to below. The display panel of the embodiment of the invention is alternately and electrically connected with the first driving unit and the second driving unit through the third data line in the boundary area between the first display area and the second display area, and the boundary area is alternately driven by the first driving unit and the second driving unit, so that the boundary area between the first display area and the second display area can be gradually transited in the display process, and further, the boundary line formed in the boundary area when the display panel displays the low-gray-scale pure gray picture sensitive to human eyes is weakened or eliminated, thereby improving the display effect of the display panel.
Further, the display panel includes at least one selection switch element. In the embodiment shown in fig. 2, a selection switch element 6 is included between adjacent ones of the first display areas 1 and one of the second display areas 2. Wherein the selection switch element 6 is electrically connected to one of the third data lines 51 located in the boundary region 5, and the selection switch element 6 is used for alternately electrically connecting the third data line 51 to the first driving unit 3 and the second driving unit 4 according to the control signal.
Fig. 3 is a schematic circuit diagram of a selection switch element of a display panel according to the present invention. As shown in fig. 3, the selection switch element 6 includes a first thin film transistor 61 and a second transistor 62.
The source 611 of the first thin film transistor 61 is connected to the first driving unit 3, the drain 612 of the first thin film transistor 61 is connected to the third data line 51, and when the first thin film transistor 61 is turned on, the first driving unit 3 and the third data line 51 are electrically connected.
Similarly, the source 621 of the second thin film transistor 62 is connected to the second driving unit 4, the drain 622 of the second thin film transistor 62 is connected to the third data line 51, and when the second thin film transistor 62 is turned on, the second driving unit 4 and the third data line 51 are electrically connected.
Further, the display panel also comprises a control signal source 7. Wherein the control signal source 7 may be integrated in the same integrated circuit as the first drive unit 3 or the second drive unit 4. In the embodiments shown in fig. 2 and 3, the control signal source 7 is integrated with the first drive unit 3 in an integrated circuit 8. The control signal source 7 is configured to provide a control signal to the selection switch element 6, and further, the first thin film transistor 61 and the second thin film transistor 62 of the selection switch element 6 are alternately turned on according to the control signal provided by the control signal source 7. The control signal provided to the first thin film transistor 61 and the second thin film transistor 62 is a voltage signal. When the voltage signal is higher than the first threshold, the first thin film transistor 61 is turned on, that is, the third data line 51 is electrically connected to the first driving unit 3; when the voltage signal is lower than the second threshold, the second thin film transistor 62 is turned on, i.e., the third data line 51 is electrically connected to the second driving unit 4.
Further, the present invention also provides a driving method of the display panel shown in fig. 1 to 3. In an embodiment of the present invention, the display panel includes a first display period and a second display period in the display process, the first display period and the second display period alternating with each other. Further, the driving method includes the steps of: in the first display period, the third data line is electrically connected with the first driving unit; the third data line is electrically connected to the second driving unit in the second display period. Optionally, the first display period and the second display period are equal in duration. The duration is the display time of one frame of picture.
As shown in fig. 2 and fig. 3, in the first display period, the selection switch element 6 turns on the third data line 51 and the first driving unit 3 according to the control signal. In the second display period, the selection switch element 6 turns on the third data line 51 and the second driving unit 4 according to the control signal. The control signal sent by the control signal source 7 is a voltage signal. In the first display period, the voltage signal is higher than the first threshold, and further, the first thin film transistor 61 is turned on and the second thin film transistor 62 is turned off, so that the first driving unit 3 and the third data line 51 are electrically connected. In the second display period, the voltage signal is lower than the second threshold, and the second thin film transistor 62 is turned on and the first thin film transistor 61 is turned off, so that the second driving unit 4 and the third data line 51 are electrically connected. The display panel realizes that the third data line in the boundary area is alternately and electrically connected with the first driving unit and the second driving unit through the driving method, so that the boundary area of the display panel can be gradually transited in the display process, and further, the boundary line formed in the boundary area when the display panel displays a low-gray-scale pure gray picture sensitive to human eyes is weakened or eliminated, and the display effect of the display panel is improved.
Fig. 4 is another embodiment of the display panel of the present invention, and fig. 4 is a schematic circuit diagram of a selection switch element of another display panel according to another embodiment of the present invention. Unlike the display panel shown in fig. 2 and 3 described above, each border area includes a plurality of third data lines. The display panel comprises a plurality of selection switch elements, and each selection switch element is electrically connected with the third data lines in a one-to-one correspondence mode. The selection switch element controls the first driving unit and the second driving unit to be alternately electrically connected with the corresponding third data lines according to the control signal.
Specifically, in the embodiment shown in fig. 4, the border area 5 includes two third data lines 51 and 51 ', and the display panel includes two selection switch elements 6 and 6'. As shown in fig. 4, the selection switch element 6 is electrically connected to the third data line 51, and the selection switch element 6 'is electrically connected to the third data line 51'. The selection switch elements 6 and 6' have the same structure and may both have the structure shown in fig. 3, i.e., each include a first thin film transistor and a second thin film transistor. The selection switch element 6 controls the first driving unit 3 and the second driving unit 4 to be alternately electrically connected with the third data line 51 according to the control signal; the selection switch element 6 'controls the first driving unit 3 and the second driving unit 4 to be alternately electrically connected to the third data line 51' according to the control signal. Wherein the control signals received by the selection switch element 6 and the selection switch element 6' are provided by the same control signal source 7. In the embodiment shown in fig. 4, the control signal source 7 is integrated with the first drive unit 3 in an integrated circuit 8.
Further, in this embodiment, in the driving process of the driving method of the present invention, in the first display period, each selection switch element controls the first driving unit to be electrically connected to the corresponding third data line according to the control signal; in the second display period, each selection switch element controls the second driving unit to be electrically connected with the corresponding third data line according to the control signal. Taking fig. 4 as an example, in the first display period, the selection switching elements 6 and 6 'may control the first driving unit 3 to be electrically connected with the third data lines 51 and 51' according to the control signal. In the second display period, the selection switching elements 6 and 6 'may control the second driving unit 4 to be electrically connected with the third data lines 51 and 51' according to the control signal.
In this embodiment, since the number of the third data lines is increased in the boundary area, each of the third data lines can be alternately electrically connected to the first driving unit and the second driving unit, so that the effect of the gradual transition of the boundary area in the display process in the embodiment shown in fig. 2 can be further enhanced, and the display effect of the display panel can be improved, which is not described herein again.
It should be noted that, although the boundary region having two third data lines is illustrated in fig. 4 as an example, the boundary region is not limited to this, in other embodiments of the present invention, the boundary region may include more third data lines, for example, three, four, or five third data lines, and each third data line is electrically connected to one selection switch element, so as to achieve a gradual transition effect of the boundary region in the display process, which is not described herein again.
In addition, since in the above-mentioned embodiment shown in fig. 4, the third data lines 51 and 51 'both use the circuit connection manner shown in fig. 3 and are both controlled by the same control signal, the third data lines 51 and 51' are driven by the same driving unit (e.g., both driven by the first driving unit or both driven by the second driving unit) in the same display period. However, in other embodiments of the present invention, the third data lines 51 and 51' may also be implemented to be driven by the first driving unit and the second driving unit, respectively, in the same display period. For example, in these embodiments, the selection switch element 6 electrically connected to the third data line 51 may still use the circuit configuration in fig. 3 (i.e., the source of the first thin film transistor is connected to the first driving unit, and the source of the second thin film transistor is connected to the second driving unit). In the selection switch element 6 'electrically connected to the third data line 51', the source of the first thin film transistor is connected to the second driving unit, and the source of the second thin film transistor is connected to the first driving unit, i.e., it can be understood that the two driving units correspondingly connected to the two thin film transistors of the selection switch element shown in fig. 3 are opposite. Furthermore, after receiving the same control signal, both the selection switch elements 6 and 6 'are turned on by the first thin film transistor or both the selection switch elements 6 and 6', but because the sources of the selection switch element 6 and the selection switch element 6 'are respectively connected to the first driving unit and the second driving unit, the third data lines 51 and 51' are respectively in driving electrical connection with the first driving unit and the second driving unit, that is, the first driving unit and the second driving unit respectively drive the two third data lines in the same display period.

It should be noted that, since the two third data lines in fig. 5 are respectively controlled by two control signals, in other embodiments of the present invention, in the first display period, the selection switch element 6 may electrically connect the third data line 51 to the first driving unit 3 according to the control signal provided by the control signal source 7, and the selection switch element 6 ' may electrically connect the third data line 51 ' to the second driving unit 4 according to the control signal provided by the control signal source 7 '; in the second display period, the selection switch element 6 may electrically connect the third data line 51 to the second driving unit 4 according to the control signal provided by the control signal source 7, and the selection switch element 6 ' may electrically connect the third data line 51 ' to the first driving unit 3 according to the control signal provided by the control signal source 7 ', and these embodiments can be implemented as well. In these embodiments, since different third data lines can be controlled by different control signals, the boundary region can have greater adjustability, and further, transition in the display process is more uniform, and the display effect of the display panel is improved, which is not described herein again.
Further, the present invention also provides a display device including the display panel shown in fig. 1 to 5. Because the display device is provided with the display panel, the display panel can enable the boundary region to be in smooth transition in the display process, and further, the boundary line formed in the boundary region when the display panel displays the low-gray-scale pure gray picture sensitive to human eyes is weakened or eliminated, so that the display effect of the display device can be improved, and the description is omitted.
In summary, the display panel and the display device provided in the embodiments of the present invention are electrically connected to the first driving unit and the second driving unit alternately through the third data line in the boundary region between the first display region and the second display region, and the boundary region is driven alternately by the first driving unit and the second driving unit, so that the boundary region between the first display region and the second display region can be gradually transited in the display process, and further, the boundary line formed in the boundary region when the display panel displays the low-gray-scale pure gray image sensitive to human eyes is reduced or eliminated, thereby improving the display effect of the display panel.
