[0012] At least one group of data signal lines includes a first data signal line and a second data signal line. Both the first and second data signal lines extend along the first direction and are arranged along the second direction. The first and second data signal lines within the same data signal line group are electrically connected to the same data signal output terminal.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. Based on the basic concepts disclosed and indicated in the embodiments of this invention, all other embodiments obtained by those skilled in the art are within the scope of protection of this invention.

[0036] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention. Figure 2 yes Figure 1 A cross-sectional structural diagram along the A-A' direction. Figure 3 yes Figure 1An enlarged structural diagram of region B in the middle. See also... Figures 1-3 This invention provides a display panel including a first display area 10 and a second display area 20. The display panel also includes multiple sets of sub-pixel groups 30, multiple sets of data signal line groups 40, and multiple sets of control unit groups 50. Multiple sub-pixels 310 in the sub-pixel groups 30 are arranged along a first direction X, and each sub-pixel group 30 includes multiple first sub-pixels 311 located in the first display area 10 and multiple second sub-pixels 312 located in the second display area 20. At least one set of data signal line groups 40 includes first data signal lines 410 and second data signal lines 420. Both the first data signal lines 410 and the second data signal lines 420 extend along the first direction X and are arranged along the second direction Y. The first data signal lines 411 and... The second data signal line 412 is electrically connected to the same data signal output terminal 420, and the first data signal line 411 is located on the side of the second data signal line 412 away from the sub-pixel group 30 connected to the data signal line group 40. The first data signal line 411 is electrically connected to the first sub-pixel 311, and the second data signal line 412 is electrically connected to the second sub-pixel 312. The first direction X and the second direction Y intersect and are both parallel to the plane where the display panel is located. The control unit group 50 includes at least one control unit 510. The control unit 510 is electrically connected between the data signal output terminal 420 and the data signal line 410 and is used to control the data signal output by the data signal output terminal 420 to be transmitted to the first sub-pixel 311 and the second sub-pixel 312 in a time-division manner.

[0037] For details, see Figures 1-3 The display panel includes a first display area 10 and a second display area 20, wherein the first display area 10 can be a transparent display area and the second display area 20 can be a normal display area. The light transmittance of the first display area 10 is greater than that of the second display area 20. The display panel also includes multiple sets of sub-pixel groups 30, which are arranged along a second direction Y. Each set of sub-pixel groups 30 includes multiple sub-pixels 310, which are arranged along a first direction X. The multiple sets of sub-pixel groups 30 include a portion of sub-pixel groups 30 that overlaps with the first display area 10 along the thickness direction of the display panel. This portion of sub-pixel groups 30 includes a first sub-pixel 311 located in the first display area 10 and a second sub-pixel 312 located in the second display area 20.

[0038] It should be noted that, Figure 1 The first display area 10 is described only by way of example in the area of ​​the display panel near the top edge. The present invention does not limit this. In other embodiments, the first display area 10 may also be located in other areas of the display panel.

[0039] like Figure 2As shown, the display panel also includes an array substrate 300 and sub-pixels 310 located on the array substrate 300. The array substrate 300 can be a low-temperature polycrystalline silicon array substrate, an IGZO (indium gallium zinc oxide) array substrate, or other types of substrates with TFT arrays. The array substrate 300 is provided with multiple pixel driving circuits 500 for driving the sub-pixels 310. Each pixel driving circuit 500 is at least used to provide data signals to the sub-pixels 310. It should be noted that the specific structure of the pixel driving circuit is not limited in this embodiment of the invention. It can include two thin-film transistors and one storage capacitor (i.e., a "2T1C" pixel driving circuit), or it can include seven thin-film transistors and one storage capacitor (i.e., a "7T1C" pixel driving circuit), as long as it can normally drive the sub-pixels 310 to emit light and display. Furthermore, the structure of the thin-film transistors can be a top-gate structure or a bottom-gate structure; the structure of the thin-film transistors is not limited here. For example, if the thin-film transistor T has a top-gate structure, the array substrate 300 may include a buffer layer, an active layer, a first insulating layer, a first metal layer, an MC metal layer, and a second metal layer stacked sequentially. The channel of the thin-film transistor is located in the active layer, the gate of the thin-film transistor is located in the first metal layer, the upper and lower plates of the storage capacitor may be located in the first metal layer and the MC metal layer, respectively, and the source and drain of the thin-film transistor are located in the second metal layer. Further, the sub-pixel 310 includes a functional layer 300a near the array substrate 300. Taking an organic light-emitting display panel as an example, 300a includes a first electrode, a light-emitting functional layer, and a second electrode stacked sequentially. The drain of the thin-film transistor T is connected to the first electrode. In addition, the light-emitting functional layer may be a stack of layers including a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer. Specifically, when no voltage is applied to the first electrode and the second electrode, the sub-pixel 310 does not emit light. When a voltage is applied to the first electrode and the second electrode, the first electrode injects holes into the hole injection layer, and the second electrode injects electrons into the electron injection layer. The holes and electrons recombine in the light-emitting layer to form photoexcitons, which emit light.

[0040] like Figure 3As shown, the display panel also includes multiple sets of data signal line groups 40. Each set of data signal line groups 40 includes a data signal line 410, which is electrically connected to a corresponding sub-pixel group 30, thereby providing data signals to the sub-pixel group 30. At least one set of data signal line groups 40 includes a first data signal line 411 and a second data signal line 412. That is, among the multiple sets of data signal line groups 40, there is a portion of data signal line groups 40 that overlaps with the first display area 10 along the thickness direction of the display panel. This portion of data signal line groups 40 includes a first data signal line 411 and a second data signal line 412. Both the first data signal line 411 and the second data signal line 412 extend along a first direction X and are arranged along a second direction Y. The first data signal line 411 is electrically connected to the first sub-pixel 311 located in the first display area 10, and is used to provide data signals to the first sub-pixel 311. The data signal, the second data signal line 412 is electrically connected to the second sub-pixel 312 located in the second display area 20, and is used to provide data signals to the second sub-pixel 312. The first data signal line 411 and the second data signal line 412 in the same data signal line group 40 are provided with data signals by the same data signal output terminal 420. The data signals of the first data signal line 411 and the second data signal line 412 are controlled to be transmitted to the first sub-pixel 311 and the second sub-pixel 312 in a time-division manner by at least one control unit 510 connected between the data signal output terminal 420 and the data signal line 410. Since the first display area 10 is a transparent display area and the second display area 20 is a normal display area, in order to ensure display uniformity, the data signal transmitted by the first data signal line 411 may be different from the data signal transmitted by the second data signal line 412. That is to say, the data signal transmitted by the first data signal line 411 is outside the range of the normal data signal (the normal data signal can be understood as the data signal required for the normal display of the second sub-pixel 312 of the second display area 20). As a result, the first data signal line 411 will generate a coupling capacitance with the second sub-pixel 312 of the second display area 220, causing signal disturbance.

[0041] To address this, this embodiment of the invention sets the first data signal line 411 in the same data signal line group 40 to be located on the side of the second data signal line 412 away from the sub-pixel group 30 electrically connected to the data signal line group 40. That is, in the same data signal line group 40, the second data signal line 412, which transmits normal data signals, is located between the first data signal line 411 and the sub-pixel group 30, where the transmitted data signals are outside the range of normal data signals. In this way, the second data signal line 412 shields the signal disturbance of the first data signal line 411, preventing the data signals transmitted by the second data signal line 412 from affecting the light emission brightness of some sub-pixels of the sub-pixel group 30, thereby improving the display effect of the display panel.

[0042] It should be noted that the data signal transmitted by the first data signal line 411 is outside the range of the normal data signal. This can be understood as follows: when the array substrate 300 includes N-type thin-film transistors, in order to ensure the display uniformity of the first display area 10 and the second display area 20, when scanning the first display area 10, the data signal transmitted by the first data signal line 411 needs to be greater than the normal data signal to improve the luminous brightness of the first sub-pixel 311 in the first display area 10; while when the array substrate 300 includes P-type thin-film transistors, in order to ensure the display uniformity of the first display area 10 and the second display area 20, when scanning the first display area 10, the data signal transmitted by the first data signal line 411 needs to be less than the normal data signal to improve the luminous brightness of the first sub-pixel 311 in the first display area 10.

[0043] In summary, the embodiments of the present invention, by setting at least one control unit between the data signal line and the data signal output terminal, control the data signals output by the first data signal line and the second data signal line to be transmitted to the first sub-pixel and the second sub-pixel in a time-division manner. In the same data signal line group, the first data signal line is located on the side of the second data signal line away from the sub-pixel group connected to the data signal line group. That is, in the interconnected data signal line group and sub-pixel group, the second data signal line is located between the first data signal line and the sub-pixel group. Thus, the second data signal line shields the signal disturbance caused by the first data signal line outside the normal data signal range, thereby improving the display effect of the display panel.

[0044] Based on the above embodiments, see below. Figure 3 The control unit group 50 includes a first control unit 511, which is electrically connected between the data signal output terminal 420 and the first data signal line 411.

[0045] Specifically, such as Figure 3As shown, the control unit group 50 may include a control unit 510, which may be a first control unit 511. The first control unit 511 is electrically connected between the data signal output terminal 420 and the first data signal line 411. That is, the input terminal of the first control unit 511 can be electrically connected to the data signal output terminal 420, and the output terminal of the first control unit 511 can be electrically connected to the first data signal line 411. In addition, the data signal output terminal 420 is also electrically connected to the second data signal line 412, and the second data signal line 412 is electrically connected to the second sub-pixel 312. Thus, when scanning the first display area 10, the first control unit 511 is turned on, and the first data signal line 411 transmits data signals to the first sub-pixel. The first sub-pixel 311 is illuminated by the first data signal line 412. When the second display area 20 is scanned, the first control unit 511 is turned off, and the second data signal line 412 transmits a data signal to the second sub-pixel 312 to illuminate it. The signal transmitted by the second data signal line 412 is a normal data signal, while the data signal transmitted by the first data signal line is outside the range of normal data signals. By positioning the second data signal line 412 between the first data signal line 411 and the sub-pixel group 30, signal disturbances from the first data signal line 411 are shielded, preventing the data signal transmitted by the first data signal line 411 from affecting the illumination brightness of some sub-pixels in the sub-pixel group 30, thus improving the display effect of the display panel. Furthermore, in this embodiment of the invention, the data signal output from the data signal output terminal 420 can be transmitted to the first sub-pixel 311 and the second sub-pixel 312 in a time-division manner using only the first control unit 511. This simplifies the control method, simplifies the circuit structure, and reduces production costs.

[0046] In yet another embodiment, Figure 4 yes Figure 1 Another enlarged structural diagram of region B in the middle is shown below. Figure 4 The control unit group 50 includes a second control unit 512, which is electrically connected between the data signal output terminal 420 and the second data signal line 412.

[0047] Specifically, such as Figure 4As shown, the control unit group 50 may include a control unit 510, which may be a second control unit 512. The second control unit 512 is electrically connected between the data signal output terminal 420 and the second data signal line 412. That is, the input terminal of the second control unit 512 can be electrically connected to the data signal output terminal 420, and the output terminal of the second control unit 512 can be electrically connected to the second data signal line 412. In addition, the data signal output terminal 420 is also electrically connected to the first data signal line 411, and the first data signal line 411 is electrically connected to the first sub-pixel 311. Therefore, when scanning the first display area 10, the second control unit 512 is turned off, and the first data signal line 411 transmits data signals to the first sub-pixel 311. A first sub-pixel 311 is used to emit light. When the second display area 20 is scanned, the second control unit 511 is turned on, and the second data signal line 412 transmits a data signal to the second sub-pixel 312 to emit light. The signal transmitted by the second data signal line 412 is a normal data signal, while the data signal transmitted by the first data signal line is outside the range of normal data signals. By setting the second data signal line 412 between the first data signal line 411 and the sub-pixel group 30, signal disturbances of the first data signal line 411 are shielded, preventing the data signal transmitted by the first data signal line 411 from affecting the brightness of the sub-pixel group 30, thus improving the display effect of the display panel. In addition, in this embodiment of the invention, the data signal output from the data signal output terminal 420 can be transmitted to the first sub-pixel 311 and the second sub-pixel 312 in a time-division manner using only the second control unit 512. The control method is simple, the circuit structure is simplified, and the production cost is reduced.

[0048] Optional, Figure 5 yes Figure 1 Another enlarged structural diagram of region B in the middle is shown below. Figure 5 The control unit group 50 includes a third control unit 513 and a fourth control unit 514. The third control unit 513 is electrically connected between the data signal output terminal 420 and the first data signal line 411, and the fourth control unit 514 is electrically connected between the data signal output terminal 420 and the second data signal line 412.

[0049] Specifically, such as Figure 5As shown, the control unit group 50 may further include multiple control units 510, which may include a third control unit 513 and a fourth control unit 514. The third control unit 513 is electrically connected between the data signal output terminal 420 and the first data signal line 411, and the fourth control unit 514 is electrically connected between the data signal output terminal 420 and the second data signal line 412. That is, the input terminals of both the third control unit 513 and the fourth control unit 514 are electrically connected to the data signal output terminal 420. The output terminal of the third control unit 513 can be electrically connected to the first data signal line 411, which is electrically connected to the first sub-pixel 311. The output terminal of the fourth control unit 514 can be electrically connected to the second data signal line 412, which is electrically connected to the second sub-pixel 312. Therefore, when the display panel is scanning the first display area 10, the third control unit 513... When the display panel is scanning the second display area 20, the third control unit 513 is turned off, the fourth control unit 514 is turned on, and the data signal output by the data signal output terminal 420 is transmitted to the second sub-pixel 311 through the second data signal line 412. To ensure the uniformity of the display panel, the data signal transmitted by the second data signal line 412 is a normal data signal, while the data signal transmitted by the first data signal line 411 is outside the range of normal data signals. By setting the second data signal line 412 between the first data signal line 411 and the sub-pixel group 30, the signal disturbance of the first data signal line 411 is shielded, preventing the data signal transmitted by the first data signal line 411 from affecting the brightness of some sub-pixels of the sub-pixel group 30, thus improving the display effect of the display panel. Furthermore, by controlling the data signal transmitted to the first sub-pixel 311 through the third control unit 513 and the data signal transmitted to the second sub-pixel 312 through the fourth control unit 514, compared with the time-division multiplexing method of controlling the data signal transmission through a single control unit 510, the capacitive load of the data signal line 410 can be made more stable, which is beneficial to improving the shielding effect of data disturbance.

The second sub-pixel 312 includes a third sub-pixel 312a located in the first sub-display area 210 and a fourth sub-pixel 312b located in the second sub-display area 220. The second data signal line 412 includes a first sub-data signal line located in the first sub-display area 210.

[0051] For details, see Figure 6 and Figure 7 In other embodiments, the first display area 10 may also be located on one side of the display panel near the center area of ​​the display panel. In this case, the second display area 20 includes a first sub-display area 210 and a second sub-display area 220 located on opposite sides of the first display area 10. Along the first direction X, the first sub-display area 210 is located on the side of the first display area 10 away from the data signal output terminal 420, and the second sub-display area 220 is located on the side of the first display area 10 closer to the data signal output terminal 420. The sub-pixel 410 includes a first sub-pixel 411 and a second sub-pixel 312. The first sub-pixel 411 is located in the first display area 10, and the second sub-pixel 312 includes a third sub-pixel 312a and a fourth sub-pixel 312b.

[0052] The control unit group 50 may include multiple control units 510. The multiple control units 510 may include a fifth control unit 515 located in the first sub-display area 210 and a sixth control unit 516 located in the second sub-display area 220. The input terminal of the fifth control unit 515 is electrically connected to the data signal output terminal 420 through the first data signal line 411, and the output terminal of the fifth control unit 515 is electrically connected to the first sub-data signal line 412a. The first sub-data signal line 412a is electrically connected to the third sub-pixel 312a. The input terminal of the sixth control unit 516 is electrically connected to the data signal output terminal 420, and the output terminal of the sixth control unit 516 is electrically connected to the second sub-data signal line 412b. The second sub-data signal line 412b is electrically connected to the fourth sub-pixel 312b. In other words, the fifth control unit 515 is electrically connected between the first sub-data signal line 412a and the first data signal line 411, and the sixth control unit 516 is electrically connected between the second sub-data signal line 412b and the data signal output terminal 420. Therefore, when the display panel scans the first sub-display area 210, the fifth control unit 515 is turned on, and the sixth control unit 516 is turned off. The data signal output from the data signal output terminal 420 passes through the... A data signal line 411 and a first sub-data signal line 412a are transmitted to the third sub-pixel 312a of the first sub-display area 210. When the display panel scans the first display area 10, the fifth control unit 515 is turned off and the sixth control unit 516 is turned off. The data signal output by the data signal output terminal 420 is transmitted to the first sub-pixel 311 of the first display area 10 through the first data signal line 411. When the display panel scans the second sub-display area 220, the fifth control unit 515 is turned off and the sixth control unit 516 is turned on. The data signal output by the data signal output terminal 420 is transmitted to the fourth sub-pixel 312b of the second sub-display area 220 through the second sub-data signal line 412b.

[0053] To ensure the uniformity of the display panel, when scanning the first sub-display area 210, the data signal transmitted by the first data signal line 411 is a normal data signal. When scanning the first display area 10, the data signal of the first data signal line 411 is outside the range of normal data signals. When scanning the second sub-display area 220, the data signal transmitted by the second sub-data signal line 412b is a normal data signal. By setting the first sub-data signal line 412a between the first data signal line 411 and the sub-pixel group 30, and the second sub-data signal line 412b between the first data signal line 411 and the sub-pixel group 30, the signal disturbance of the first data signal line 411 is shielded by the first and second sub-data signal lines 412a and 412b, preventing the data signal transmitted by the first data signal line 411 from affecting the brightness of the sub-pixel group 30, thus improving the display effect of the display panel. Furthermore, when scanning the first display area 10 and the second sub-display area 220, only one sixth control unit 516 is needed to realize the time-division transmission of the data signal output from the data signal output terminal 420 to the first sub-pixel 311 and the fourth sub-pixel 312b. The control method is simple, the circuit structure is simplified, and the production cost is reduced.

[0054] Based on the above embodiments, see below. Figure 7 The first sub-data signal line 412a and the second sub-data signal line 412b are disconnected in the first display area 10, and the fifth control unit 515 and the sixth control unit 516 are connected to the same control signal line.

[0055] Specifically, such as Figure 7As shown, the second data signal line 412 includes a first sub-data signal line 412a located in the first sub-display area 210 and a second sub-data signal line 412b located in the second sub-display area 220. The first sub-data signal line 412a and the second sub-data signal line 412b are disconnected in the first display area 10. In this way, the number of traces in the first display area 10 can be reduced, and wiring space can be saved. Furthermore, the fifth control unit 515 and the sixth control unit 516 are connected to the same control signal line. When scanning the first sub-display area 210, the fifth control unit 515 and the sixth control unit 516 are simultaneously turned on, and the data signal output by the data signal output terminal 420 is transmitted to the third sub-pixel 312a through the first data signal line 411 and the first sub-data signal line 412a. When scanning the first display area 10, the fifth control unit 515 and the sixth control unit 516 are simultaneously turned off, and the data signal output by the data signal output terminal 420 is transmitted to the first sub-pixel 311 through the first data signal line 411. When scanning the second sub-display area 220, the fifth control unit 515 and the sixth control unit 516 are simultaneously turned on, and the data signal output by the data signal output terminal 420 is transmitted to the fourth sub-pixel 312b through the second sub-data signal line 412b. Thus, compared with the scheme where the five control units 515 and the sixth control unit 516 are controlled separately, the control method of the control unit is simpler.

[0056] It should be noted that when scanning the first sub-display area 210, the fifth control unit 515 and the sixth control unit 516 are simultaneously turned on. The data signal output by the data signal output terminal 420 can be transmitted to the third sub-pixel 312a through the first data signal line 411 and the first sub-data signal line 412a, and can also be transmitted to the fourth sub-pixel 312b through the second sub-data signal line 412b. However, since the scanning signal does not scan the second sub-display area 220, the fourth sub-pixel 312b does not emit light.

[0057] Optional, Figure 8 yes Figure 6 Another enlarged structural diagram of region C is shown below. Figure 8 The first sub-data signal line 412a and the second sub-data signal line 412b are connected and disposed in the first display area 10, and both the first sub-data signal line 412a and the second sub-data signal line 412b are insulated from the first sub-pixel 311.

[0058] Specifically, the second data signal line 412 includes a first sub-data signal line 412a located in the first sub-display area 210 and a second sub-data signal line 412b located in the second sub-display area 220. The first sub-data signal line 412a and the second sub-data signal line 412b are connected and disposed in the first display area 10, and both the first sub-data signal line 412a and the second sub-data signal line 412b are insulated from the first sub-pixel 311. When scanning the first sub-display area 210, the data signal transmitted by the data signal output terminal 420 is transmitted to the third sub-pixel 312a through the second data signal line 412; when scanning... When scanning the first display area 10, the data signal transmitted by the data signal output terminal 420 is transmitted to the first sub-pixel 311 through the first data signal line 411; when scanning the second sub-display area 220, the data signal transmitted by the data signal output terminal 420 is transmitted to the fourth sub-pixel 312b through the second data signal line 412. In this way, when scanning the first display area 10, the data signal is transmitted through the first data signal line 411, and when scanning the first sub-display area 210 and the second sub-display area 220 of the second display area 20, the data signal is transmitted through the second data signal line 412, which simplifies the data signal transmission method.

[0059] In yet another embodiment, Figure 9 yes Figure 6 Another enlarged structural diagram of region C is shown below. Figure 9 The second display area 20 includes a first sub-display area 210 and a second sub-display area 220. Along the first direction X, the first sub-display area 210 is located on the side of the first display area 10 away from the data signal output terminal 420, and the second sub-display area 220 is located on the side of the first display area 10 close to the data signal output terminal 420. The second sub-pixel 312 includes a third sub-pixel 312a located in the first sub-display area 210 and a fourth sub-pixel 312b located in the second sub-display area 220. The second data signal line 412 includes a first sub-data signal line 412a located in the first sub-display area 210 and a second sub-data signal line 412b located in the second sub-display area 220. The third sub-pixel 312a is electrically connected to the first sub-data signal line 412a, and the fourth sub-pixel 312b is electrically connected to the second sub-data signal line 412b. The control unit group 50 includes a seventh control unit 517, an eighth control unit 518, and a ninth control unit 519. The seventh control unit 517 is electrically connected between the first sub-data signal line 412a and the first data signal line 411. The eighth control unit 518 is electrically connected between the first data signal line 411 and the data signal output terminal 420. The ninth control unit 519 is electrically connected between the second sub-data signal line 412b and the data signal output terminal 420.

[0060] Specifically, such as Figure 6 and Figure 9As shown, when the first display area 10 is located on one side of the display panel near the center, the second display area 20 includes a first sub-display area 210 and a second sub-display area 220 located on opposite sides of the first display area 10. Along the first direction X, the first sub-display area 210 is located on the side of the first display area 10 away from the data signal output terminal 420, and the second sub-display area 220 is located on the side of the first display area 10 closer to the data signal output terminal 420. The sub-pixel 410 includes a first sub-pixel 411 and a second sub-pixel 312. The first sub-pixel 411 is located in the first display area 10, and the second sub-pixel 312 includes a third sub-pixel 312a and a fourth sub-pixel 312b. The third sub-pixel 312a is located in the first sub-display area 210, and the fourth sub-pixel 312b is located in the second sub-display area 220. The data signal line 410 includes a first data signal line 411 and a second data signal line 412. The first data signal line 411 is located in the first display area 10 and the second display area 20. The second data signal line 412 includes a first sub-data signal line 412a located in the first sub-display area 210 and a second sub-data signal line 412b located in the second sub-display area 220.

[0061] The control unit group 50 may include multiple control units 510. The multiple control units 510 may include a seventh control unit 517 located in the first sub-display area 210, and an eighth control unit 518 and a ninth control unit 519 located in the second sub-display area 220. The input terminal of the seventh control unit 517 is electrically connected to the output terminal of the eighth control unit 518 through a first data signal line 411. The input terminal of the eighth control unit 518 is electrically connected to the data signal output terminal 420. The output terminal of the seventh control unit 517 is electrically connected to the first sub-data signal line 412a. The first sub-data signal line 412a is electrically connected to the third sub-pixel 312a. The input terminal of the ninth control unit 519 is electrically connected to the data signal output terminal 420, and the output terminal of the ninth control unit 519 is electrically connected to the second sub-data signal line 412b. The second sub-data signal line 412b is electrically connected to the fourth sub-pixel 312b. In other words, the seventh control unit 517 is electrically connected between the first sub-data signal line 412a and the first data signal line 411, the eighth control unit 518 is electrically connected between the first data signal line 411 and the data signal output terminal 420, and the ninth control unit 519 is electrically connected between the second sub-data signal line 412b and the data signal output terminal 420. Therefore, when scanning the first sub-display area 210, the seventh control unit 517 and the eighth control unit 518 are turned on, while the ninth control unit 519 is turned off, and the data signal output... The data signal output from the output terminal 420 is transmitted to the third sub-pixel 312a of the first sub-display area 210 through the first data signal line 411 and the first sub-data signal line 412a. When scanning the first display area 10, the seventh control unit 517 and the ninth control unit 519 are turned off, and the eighth control unit 518 is turned on. The data signal output from the data signal output terminal 420 is transmitted to the first sub-pixel 311 of the first display area 10 through the first data signal line 411. When scanning the second sub-display area 220, the seventh control unit 517 and the eighth control unit 518 are turned off, and the ninth control unit 519 is turned on. The data signal output from the data signal output terminal 420 is transmitted to the fourth sub-pixel 312b of the second sub-display area 220 through the second sub-data signal line 412b.

[0062] To ensure the uniformity of the display panel, when scanning the first sub-display area 210, the data signal transmitted by the first data signal line 411 is a normal data signal. When scanning the first display area 10, the data signal of the first data signal line 411 is outside the range of normal data signals. When scanning the second sub-display area 220, the data signal transmitted by the second sub-data signal line 412b is a normal data signal. By setting the first sub-data signal line 412a to be located between the first data signal line 411 and the sub-pixel group 30, and the second sub-data signal line 412b to be located between the first data signal line 411 and the sub-pixel group 30, the signal disturbance of the first data signal line 411 is shielded by the first and second sub-data signal lines 412a and 412b, preventing the data signal transmitted by the first data signal line 411 from affecting the brightness of some sub-pixels of the sub-pixel group 30, thus improving the display effect of the display panel. Furthermore, when scanning the first display area 10 and the second sub-display area 220, the data signal transmitted to the first sub-pixel 311 is controlled by the eighth control unit 518, and the data signal transmitted to the fourth sub-pixel 312b is controlled by the ninth control unit 519. Compared with the time-division method of controlling the data signal transmission by a single control unit 510, the capacitive load of the data signal line 410 can be made more stable, which is beneficial to improving the shielding effect of data disturbance.

[0063] Based on the above embodiments, see below. Figure 9 The first sub-data signal line 412a and the second sub-data signal line 412b are disconnected in the first display area 10. The seventh control unit 517 and the ninth control unit 519 are connected to the same control signal line. The seventh control unit 517 and the eighth control unit 518 are connected to different control signal lines and receive enable control signals in a time-division manner.

[0064] Specifically, such as Figure 9As shown, the second data signal line 412 includes a first sub-data signal line 412a located in the first sub-display area 210 and a second sub-data signal line 412b located in the second sub-display area 220. The first sub-data signal line 412a and the second sub-data signal line 412b are disconnected in the first display area 10, thus reducing the number of traces in the first display area 10 and saving wiring space. Furthermore, the seventh control unit 517 and the ninth control unit 519 are connected to the same control signal line, while the seventh control unit 517 and the eighth control unit 518 are connected to different control signal lines. When scanning the first sub-display area 210, the seventh control unit 517, the eighth control unit 518, and the ninth control unit 519 are simultaneously activated. The data signal output from the data signal output terminal 420 is transmitted to the third sub-pixel 312a through the first data signal line 411 and the first sub-data signal line 412a. When scanning the first display area 10, the seventh control unit 517 and the ninth control unit 519 are simultaneously activated. When the time limit is reached, the eighth control unit 518 is turned on, and the data signal output by the data signal output terminal 420 is transmitted to the first sub-pixel 311 through the first data signal line 411. When scanning the second sub-display area 220, the seventh control unit 517 and the ninth control unit 519 are turned on simultaneously, the eighth control unit 518 is turned off, and the data signal output by the data signal output terminal 420 is transmitted to the fourth sub-pixel 312b through the second sub-data signal line 412b. Thus, compared with the scheme of separate control of the seventh control unit 517 and the ninth control unit 519, the control method of the control unit is simpler.

[0065] Optional, Figure 10 yes Figure 6 Another enlarged structural diagram of region C is shown below. Figure 10 In other embodiments, the control unit group 50 may include a plurality of control units 510. The plurality of control units 510 may include a seventh control unit 517 and a tenth control unit 5110 located in the first sub-display area 210, and an eighth control unit 518 and a ninth control unit 519 located in the second sub-display area 220. The seventh control unit 517 is electrically connected between the first sub-data signal line 412a and the tenth control unit 5110. The tenth control unit 5110 is electrically connected between the seventh control unit 517 and the first data signal line 411. The eighth control unit 518 is electrically connected between the first data signal line 411 and the data signal output terminal 420. The ninth control unit 519 is electrically connected between the second sub-data signal line 412b and the data signal output terminal 420.

[0066] In yet another embodiment, Figure 11 yes Figure 6 Another enlarged structural diagram of region C is shown below. Figure 11Multiple sub-pixel groups 30 are arranged along the second direction Y, and a signal shielding line 60 is also included between any two adjacent sub-pixel groups 30 along the second direction Y.

[0067] Specifically, such as Figure 11 As shown, the display panel includes multiple sub-pixel groups 30, which are arranged along the second direction Y. The data signal group 40 includes a first data signal line 411 and a second data signal line 412. In the same data signal line group 40, the first data signal line 411 is located on the side of the second data signal line 412 away from the sub-pixel group 30. That is, in the interconnected sub-pixel groups 30 and data signal group 40, the first data signal line 411 is located on the outermost side. Consequently, the first data signal line 411 is relatively close to the adjacent sub-pixel group 30. Since the data signal transmitted by the first data signal line 411 is outside the range of normal data signals, the data signal transmitted by the first data signal line 411 will cause signal disturbance to the adjacent sub-pixel group 30. Therefore, by setting a signal shielding line 60 between any two adjacent sub-pixel groups 30, where the signal shielding line 60 can be a power signal line set between adjacent sub-pixel groups 30, the signal disturbance of the first data signal line 411 is shielded by the signal shielding line 60, so as to avoid affecting the light emission brightness of the adjacent sub-pixel groups.

[0068] In yet another embodiment, Figure 12 yes Figure 1 Another enlarged structural diagram of region B in the middle is shown below. Figure 12 The display panel also includes a transition area 70 between the first display area 10 and the second display area 20. The transition area 70 includes a fifth sub-pixel 710, which is connected to both the first data signal line 411 and the second data signal line 412.

[0069] Specifically, such as Figure 12As shown, the display panel also includes a transition area 70 between the first display area 10 and the second display area 20. It can be understood that the transition area 70 is located at the boundary between the first display area 10 and the second display area 20. The sub-pixel group 30 includes a first sub-pixel 310 located in the first display area 10, a second sub-pixel 312 located in the second display area 20, and a fifth sub-pixel 710 located in the transition area 70. When the transition area finishes scanning the first display area 10 and starts scanning the second display area 20, it needs to switch from the first data signal line 411 to the second data signal line 412. That is, the third control unit 513 needs to be turned off and the fourth control unit 514 needs to be turned on. During this process, the second data signal line 412 in the transition area 70 will undergo a relatively long charging and discharging process, which will cause the data signal transmitted by the second data signal line 412 after the switch to not reach the normal data signal in time. Therefore, by setting the fifth sub-pixel 710 located in the transition area 70 to connect the first data signal line 411 and the second data signal line 412 at the same time, the data signal of the second data signal line 412 can reach the requirement of the normal data signal in time.

[0070] In yet another embodiment, Figure 13 yes Figure 1 Another enlarged structural diagram of region B in the middle is shown below. Figure 13 The second display area 20 also includes at least one switch circuit 230, which is electrically connected between the second data signal line 412 and the control unit group 50. The input terminal of the switch circuit 230 is electrically connected to the fixed potential signal terminal 240.

[0071] Specifically, such as Figure 13 As shown, the control unit group 50 includes a third control unit 513 and a fourth control unit 514. The third control unit 513 is electrically connected between the data signal output terminal 420 and the first data signal line 411, and the fourth control unit 514 is electrically connected between the data signal output terminal 420 and the second data signal line 412. When the display panel is scanning the first display area 10, the third control unit 513 is turned on, and the fourth control unit 514 is turned off. The data signal output by the data signal output terminal 420 is transmitted to the first sub-pixel 311 through the first data signal line 411, that is, during the scanning of the first display area 10... When the first display area 10 is in operation, the second data signal line 412 is set to float. A switch circuit 230 is then set between the second data signal line 412 and the fourth control unit 514. The input terminal of the switch circuit 230 is electrically connected to the fixed potential signal terminal 240, and the output terminal of the switch circuit 230 is electrically connected to the second data signal line 412. Thus, when scanning the first display area 10, the switch circuit 230 is turned on, and a fixed potential signal is provided to the second data signal line 412 through the fixed potential signal terminal 240, which can further shield the signal disturbance of the first data signal line 411.

[0072] Optionally, based on the above embodiments, see also... Figure 3 The first display area 10 includes a transparent display area, and the second display area 20 surrounds at least a portion of the first display area 10. The opening area of ​​the first sub-pixel 311 is smaller than the opening area of ​​the second sub-pixel 312.

[0073] Specifically, the transparent display area can house devices such as cameras and fingerprint recognition modules. Therefore, it is necessary to reduce the area of ​​the sub-pixels in the transparent display area to improve the transmittance of the transparent display area. That is, by setting the opening area of ​​the first sub-pixel 311 to be smaller than the opening area of ​​the second sub-pixel 312, the transmittance of the first display area 10 can be guaranteed. Furthermore, during the driving process, the display uniformity of the display panel can be guaranteed by setting the driving voltage of the first sub-pixel 311 to be greater than the driving voltage of the second sub-pixel 312.

[0074] Based on the same inventive concept, embodiments of the present invention also provide a method for driving a display panel. Figure 14 This is a flowchart illustrating a driving method for a display panel according to an embodiment of the present invention. See also... Figure 3 and Figure 14 The display panel includes a first display area and a second display area. It also includes multiple sets of sub-pixel groups, multiple sets of data signal line groups, and multiple sets of control unit groups. Multiple sub-pixels in each sub-pixel group are arranged along a first direction, and each sub-pixel group includes multiple first sub-pixels located in the first display area and second sub-pixels located in the second display area. At least one set of data signal line groups includes first data signal lines and second data signal lines. Both the first and second data signal lines extend along the first direction and are arranged along a second direction. The first and second data signal lines within the same data signal line group are electrically connected to the same data signal output terminal. The first data signal line is located on the side of the second data signal line away from the sub-pixel group connected to the data signal line group. The first data signal line is electrically connected to the first sub-pixel, and the second data signal line is electrically connected to the second sub-pixel. The first and second directions intersect and are both parallel to the plane of the display panel. Each control unit group includes at least one control unit electrically connected between the data signal output terminal and the data signal lines. Based on this, the driving method for the display panel provided in this embodiment of the invention includes:

[0075] S110. In the first stage, a first control signal is output to the control unit to control the data signal output from the data signal output terminal to be transmitted to the first sub-pixel through the first data signal line.

[0076] The first stage can be the scanning stage of the first display area, which can be a transparent display area. Since the transparent display area needs to house devices such as cameras and fingerprint recognition modules, the opening area of ​​the first sub-pixel in the first display area needs to be smaller than the opening area of ​​the second sub-pixel in the second display area to ensure the transmittance of the first display area. Therefore, in the first stage, a first control signal needs to be output to the control terminal of the control unit to enable the control unit to conduct. Data signals are output to the first data signal line through the data signal output terminal. At this time, the data signal transmitted by the first data signal line is outside the range of normal data signals, which will generate coupling capacitance and cause signal disturbance, thereby affecting the light emission brightness of other sub-pixels. The signal disturbance is shielded by the second data signal line set between the first data signal line and the sub-pixel, thereby improving the display effect of the display panel.

[0077] S120. In the second stage, a second control signal is output to the control unit to control the data signal output from the data signal output terminal to be transmitted to the second sub-pixel through the second data signal line.

[0078] The second stage can be the scanning stage of the second display area, which can be the normal display area. In the second stage, a second control signal needs to be output to the control unit to make the control unit stop. The data signal output terminal outputs a data signal to the second data signal line. At this time, the data signal transmitted by the second data signal line is a normal data signal to ensure the uniformity of the display of the first display area and the second display area.

[0079] In summary, in this embodiment of the invention, the first data signal line and the second data signal line within the same data signal line group are electrically connected to the same data signal output terminal, and the first data signal line is located on the side of the second data signal line away from the sub-pixel group connected to the data signal line group. Thus, in the first stage, when the control unit controls the first data signal line to output a data signal to the first sub-pixel, the second data signal line shields the signal disturbance of the first data signal line outside the range of the normal data signal, preventing the data signal transmitted by the second data signal line from affecting the luminous brightness of the sub-pixel group, thereby improving the display effect of the display panel.

[0080] Based on the same inventive concept, embodiments of the present invention also provide a display device.
