Abstract
Description
Display panels, display modules and terminal equipment Technical Field
[0001] The present application relates to the field of display technology, and in particular to a display panel, a display module and a terminal device. Background Art
[0002] Compared with hole-punch and waterdrop-shaped screens, the notch area of the notch-shaped screen has a much lower pixel setting density than the non-notch area. Therefore, the capacitance difference of the scanning lines in the notch area and the non-notch area is relatively large. This difference will lead to differences in the reset and write stages of the pixel circuit, and ultimately the display effects of the two areas are different, resulting in problems with screen display in the notch area. In order to reduce this capacitance difference, it is urgently necessary to provide a display panel to compensate for the capacitance difference of the scanning lines in the notch area and the non-notch area.
[0003] Therefore, the existing display panel has a technical problem that the irregular display area of the display area and the normal display area are displayed separately. SUMMARY OF THE INVENTION

[0017] Modes for Carrying Out the Invention
[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; and "inside" and "outside" refer to the outline of the device.
[0019] Please refer to Figures 1, 2, 3 and 4. The display panel provided in the present application includes a driving unit 30, a first scanning line 10 and a second scanning line 20 connected to the driving unit 30 and transmitting different signals, the first scanning line 10 includes a first routing line 101 located in the special-shaped display area 3, and the second scanning line 20 includes a second routing line 201 located in the special-shaped display area 3. The display panel includes a first compensation line 40 and a second compensation line 50. The first compensation line 40 and the first routing line 101 are connected to the same signal, and the first compensation line 40 and the first routing line 101 are overlapped in the film thickness direction. The second compensation line 50 and the second routing line 201 are connected to the same scanning signal, and the second compensation line 50 and the second routing 201 are overlapped in the film thickness direction.
[0020] Among them, the first scan line 10 also includes a third line 102 located in the normal display area 4, the second scan line 20 also includes a fourth line 202 located in the normal display area 4, the first line 101 and the third line 102 are insulated, and the second line 201 and the fourth line 202 are insulated.
[0021] The non-display area 2 of the display panel includes a GOA area 7 , and the driving unit 30 is disposed in the GOA area 7 .
[0022] The non-display area of the display panel is further provided with a VSS wiring 60 , and the VSS wiring 60 is provided on a side of the special-shaped winding area 4 away from the display area 1 .
[0023] The display panel includes a display area 1 and a non-display area 2. The display area 1 includes an irregular display area 3 and a normal display area 4. The pixel setting density in the irregular display area 3 is less than the pixel setting density in the normal display area 4.
[0024] It can be understood that since the pixel setting density in the special-shaped display area 3 is much smaller than the pixel setting density in the normal display area 4, there will be a large difference in the capacitance of the scanning lines in the special-shaped display area 3 and the normal display area 4. By setting the compensation line to compensate for the capacitance of the scanning lines in the special-shaped display area 3, the capacitance of the same type of scanning lines in the special-shaped display area 3 and the normal display area 4 will tend to be the same.
[0025] It should be noted that the overlapping arrangement in the film thickness direction means that the arrangement can be partially overlapping or overlapped.
[0026] In this embodiment, by setting the first compensation line 40 and the second compensation line 50, the first compensation line 40 and the first wiring 101 are overlapped in the film thickness direction, and the second compensation line 50 and the second wiring 201 are overlapped in the film thickness direction, and the capacitance compensation is performed on the first wiring 101 of the first scanning line 10 and the second wiring 201 of the second scanning line 20 located in the special-shaped display area 3, respectively, to reduce the capacitance difference between the first scanning line 10 and the second scanning line 20 in the special-shaped display area 3 and the normal display area 4, thereby reducing the risk of split screen between the special-shaped display area 3 and the normal display area 4.
[0027] The technical solution of this application is now described in conjunction with specific embodiments.
[0028] The scan lines of the present application include Pscan scan lines, Nscan scan lines, and EM scan lines. The priority of capacitance compensation for the Pscan scan lines, Nscan scan lines, and EM scan lines is Pscan scan lines>Nscan scan lines>EM scan lines. Due to consideration of the space for setting compensation lines in the non-display area 2, the present application gives priority to compensating the first scan line 10 and the second scan line 20, wherein the first scan line 10 can be the Pscan scan line and the second scan line 20 can be the Nscan scan line; in addition, it can be understood that when there is sufficient space in the non-display area 2 for setting compensation lines, a third compensation line can also be set. The third compensation line is used to compensate for the capacitance of the EM scan line in the special-shaped display area 3, so that the capacitance of the EM scan line in the special-shaped display area 3 is close to the capacitance of the EM scan line in the normal display area 4.
[0029] Please refer to Figure 2. The shapes and settings of the first compensation line and the second compensation line in Figure 2 are only for reference. Both ends of the compensation line need to be connected to corresponding compensation signals. For example: the first compensation line compensates the first routing line, and the first compensation line and the first routing line are connected to the same signal, that is, when the first routing line is a Pscan scanning line and is connected to the Pscan scanning line signal, the first compensation line also needs to be connected to the Pscan scanning line signal; similarly, for the second compensation line to compensate the second routing line, the second compensation line and the second routing line are connected to the same signal, that is, when the second routing line is an Nscan scanning line and is connected to the Nscan scanning line signal, the second compensation line also needs to be connected to the Nscan scanning line signal.
[0030] The driving unit 30 includes a Pscan driving unit 30, an Nscan driving unit 30, and an EM driving unit 30. The Pscan scanning line is electrically connected to the Pscan driving unit 30 and transmits a Pscan signal. The Nscan scanning line is electrically connected to the Nscan driving unit 30 and transmits a Pscan signal. The EM scanning line is electrically connected to the EM driving unit 30 and transmits a Pscan signal. Specifically, the difference between the Pscan scanning line, the Nscan scanning line, and the EM scanning line can be seen in FIG5. FIG5 is a 7T2C circuit structure diagram, wherein T1 is a driving transistor, T2 to T7 are switching transistors, and the Pscan signal, Nscan signal, and EM signal are electrically connected to each transistor. The input relationship of the tube is shown in the figure, where Pscan(n) is the Pscan signal of a row of scan lines, Pscan(n-1) is the Pscan signal of the row above Pscan(n), Nscan(T3) is the Nscan signal at the gate of the T3 switching transistor, Nscan(T4) is the Nscan signal at the gate of the T4 switching transistor, VDD is a constant voltage high level, VSS is a constant voltage low level, and Vdata is a data line signal; it should be noted that the circuit diagram shown in Figure 5 is only an example to illustrate the connection relationship and functional difference of the Pscan scan line, Nscan scan line, and EM scan line. This application includes but is not limited to this circuit structure, and other circuit structures should also fall within the scope of protection of this application.
[0031] The present application may be an LTPO display panel. Other display panels with the technical problem of split-screen display of the irregular display area 3 and the normal display area 4 of the display area 1 also fall within the scope of protection of the present application. The following embodiments are explained using the LTPO display panel as an example.
[0032] The special-shaped display area 3 of the present application may be a Notch area, which may also be called a bangs area or a gap area, and the normal display area 4 is the normal display area 1 .
[0033] In one embodiment, referring to FIG. 1 , the first scan line 10 is a Pscan scan line, and the second scan line 20 is an Nscan scan line.
[0034] It can be understood that, according to the compensation priority, the first scan line 10 is the Pscan scan line and the second scan line 20 is the Nscan scan line. After compensation, it is more conducive to reducing the risk of split screen between the special-shaped display area 3 and the normal display area 4.
[0035] In one embodiment, the display panel further includes a third scan line, and the third scan line is an EM scan line.
[0036] The display panel further includes a third compensation line, the EM scanning line includes a fifth line located in the special-shaped display area 3 and a sixth line located in the normal display area 4, and the third compensation line and the fifth line are overlapped in the film thickness direction.
[0037] It can be understood that by overlapping the third compensation line and the fifth line in the film thickness direction, the capacitance value of the fifth line can be compensated, so that the capacitance between the fifth line and the sixth line tends to be the same, further reducing the risk of split screen between the special-shaped display area 3 and the normal display area 4.
[0038] In one embodiment, referring to Figure 6, the display panel is an LTPO display panel, which includes a substrate 110, a plurality of metal layers arranged above the substrate 110, and a plurality of insulating layers, the plurality of metal layers include a first gate layer, a second gate layer, a third gate layer, a first source-drain layer, a second source-drain layer, a third source-drain layer, and an anode layer sequentially arranged above the substrate 110, and the insulating layer is arranged between adjacent metal layers.

A first gate layer 170 is provided, a second gate insulating layer 180 is provided on the side of the first gate layer 170 away from the substrate 110, a second gate layer 190 is provided on the side of the second gate insulating layer 180 away from the substrate 110, a first interlayer insulating layer 200 is provided on the side of the second gate layer 190 away from the substrate 110, a second active layer 210 is provided on the side of the first interlayer insulating layer 200 away from the substrate 110, and a third active layer 210 is provided on the side of the second active layer 210 away from the substrate 110. A gate insulating layer 220 is provided, and a third gate layer 230 is provided on the side of the third gate insulating layer 220 away from the substrate 110. A second interlayer insulating layer 240 is provided on the side of the third gate layer 230 away from the substrate 110. A first source-drain electrode layer 250 is provided on the side of the second interlayer insulating layer 240 away from the substrate 110. A first planarizing layer 260 is provided on the side of the first planarizing layer 260 away from the substrate 110. Two source and drain layers 270, a second flat layer 280 is provided on the side of the second source and drain layer 270 away from the substrate 110, a third source and drain layer 290 is provided on the side of the second flat layer 280 away from the substrate 110, a third flat layer 300 is provided on the side of the third source and drain layer 290 away from the substrate 110, an anode layer 310 is provided on the side of the third flat layer 300 away from the substrate 110, and a pixel definition layer 320 is provided on the side of the anode layer 310 away from the substrate 110.
[0040] In one embodiment, referring to FIG. 3 , a first wiring 101 and a second wiring 201 are disposed in the special-shaped winding area 5 , and the first compensation line 40 and the second compensation line 50 are disposed in the special-shaped winding area 5 .
[0041] The first line 101 may be a Pscan scanning line, and the second line 201 may be an Nscan scanning line.
[0042] The special-shaped winding area 5 is used for winding various lines, including but not limited to Pscan scanning lines, Nscan scanning lines, and EM scanning lines.
[0043] It is understandable that by using the existing special-shaped winding area 5 to set the first compensation line 40 and the second compensation line 50, there is no need to increase the width of the display panel frame to set the first compensation line 40 and the second compensation line 50, which is conducive to achieving a narrow frame design.
[0044] In this embodiment, by disposing the first compensation line 40 and the second compensation line 50 in the existing special-shaped winding area 5 , the frame width can be reduced to achieve a narrow frame.
[0045] In one embodiment, referring to FIG. 4 , the non-display area further includes an additional compensation area 6 , the non-display area is provided with a VSS trace 60 , the additional compensation area 6 is located between the special-shaped display area 3 and the VSS trace 60 , and the first compensation line 40 and the second compensation line 50 are provided in the additional compensation area 6 .
[0046] The additional compensation area 6 may be an area formed by increasing the width of the frame, or may be an area outside the special-shaped winding area 5 .
[0047] The first line 101 may be a Pscan scanning line, and the second line 201 may be an Nscan scanning line.
[0048] It can be understood that since both the Pscan scan line and the Nscan scan line can be compensated by setting compensation lines in the additional compensation area 6, for the implementation method in which the Pscan scan line performs capacitance compensation in the additional compensation area 6, this implementation method also uses the additional compensation area 6 to compensate the Nscan scan line. The Nscan scan line and the Pscan scan line share the additional compensation area 6 for compensation, and no additional area is required to compensate the Nscan scan line, thereby not increasing the border width, which is conducive to narrow border design.
[0049] It can be understood that since the wiring of the special-shaped winding area 5 is relatively dense and there is a problem of insufficient space at the display panel frame, based on this, an additional compensation area 6 can be added to place the compensation line, and the first line 101, the second line 201, and the third line can all be wound to the additional compensation area 6. The compensation line is overlapped with at least one of the first line 101, the second line 201, and the third line in the additional compensation area 6, which can increase the capacitance of at least one of the first line 101, the second line 201, and the third line, thereby reducing the risk of split screen between the special-shaped display area 3 and the normal display area 4.
[0050] In this embodiment, since the space of the existing non-display area 2 is limited, by increasing the border width to set an additional additional compensation area 6 or forming the additional compensation area 6 on both sides of the special-shaped winding area 5, more first compensation lines 40 can be set, thereby further increasing the overlapping area between the first compensation line 40 and the first routing line 101, and more second compensation lines 50 can be set, thereby further increasing the overlapping area between the second compensation line 50 and the second routing line 201; enough first compensation lines 40 can be set to make the capacitance of the first routing line 101 and the third routing line 102 tend to be the same, and enough second compensation lines 50 can be set to make the capacitance of the second routing line 201 and the fourth routing line 202 tend to be the same.
[0051] In some embodiments, the first scanning line 10 and the second scanning line 20 can be respectively provided in the same layer as any two different metal layers.
[0052] Furthermore, the first compensation line 40 is disposed in a metal layer adjacent to the first scan line 10 , and the second compensation line 50 is disposed in a metal layer adjacent to the second scan line 20 .
[0053] Here, the first scanning line 10 is a Pscan scanning line, and the second scanning line 20 is an Nscan scanning line.
[0054] For the Pscan scanning line, the Pscan scanning line can be set in the same layer as any film layer of the first gate layer, the second gate layer, the third gate layer, the first source and drain layer, the second source and drain layer, the third source and drain layer, and the anode layer.
[0055] For example: the Pscan scanning line can be set in the same layer as the first gate layer, and the first compensation line 40 is set in the same layer as the second gate layer. Since the first compensation line 40 and the first routing line 101 in the Pscan scanning line are located in adjacent metal layers, the capacitance of the first routing line 101 can be increased by overlapping the first compensation line 40 and the first routing line 101.
[0056] For another example, the Pscan scanning line can be provided in the same layer as the second gate layer. In this case, the first compensation line 40 can be provided in the same layer as the first gate layer or the third gate layer.
[0057] Similarly, for the Nscan scanning line, the Nscan scanning line can be set in the same layer as any film layer of the first gate layer, the second gate layer, the third gate layer, the first source and drain layer, the second source and drain layer, the third source and drain layer, and the anode layer, and the Nscan scanning line and the Pscan scanning line are set in different layers.
[0058] For example: the Nscan scanning line can be set in the same layer as the first gate layer, and the second compensation line 50 is set in the same layer as the second gate layer. Since the second compensation line 50 and the second routing line 201 in the Nscan scanning line are located in adjacent metal layers, the capacitance of the second routing line 201 can be increased by overlapping the second compensation line 50 and the second routing line 201.
[0059] For another example, the Nscan scanning line can be provided in the same layer as the second gate layer. In this case, the second compensation line 50 can be provided in the same layer as the first gate layer or the third gate layer.
[0060] For another example, the Nscan scanning line can be provided in the same layer as the third gate layer. In this case, the second compensation line 50 can be provided in the same layer as the first gate layer or the third gate layer.
[0061] In one embodiment, referring to Figures 7 and 8, the first wiring 101 is arranged in the same layer as the third gate layer, the first compensation line 40 is arranged in the same layer as the first source and drain layer, the second wiring 201 is arranged in the same layer as the second source and drain layer, and the second compensation line 50 is arranged in the same layer as the third source and drain layer or the anode layer.
[0062] It can be understood that since the first compensation line 40 is provided on the side of the second wiring 201 close to the substrate 110, the first compensation line 40 can also be arranged to overlap with the second wiring 201. Then, the second wiring 201 can further increase the capacitance of the second wiring 201 of the special-shaped display area 3 through the overlap of the first compensation line 40 and the second compensation line 50, so that the capacitance of the special-shaped display area 3 and the normal display area 4 tend to be the same.
[0063] In one embodiment, referring to FIG. 9 , the second wiring 201 is disposed on the same layer as the third gate layer, and the second compensation line 50 is disposed on the same layer as the first source and drain layer.
[0064] In one embodiment, the first wiring 101 is arranged in the same layer as the second gate layer, the first compensation line 40 is arranged in the same layer as the third gate layer, the second wiring 201 is arranged in the same layer as the first source and drain layer, and the second compensation line 50 is arranged in the second source and drain layer.
[0065] The present application provides a display panel that simultaneously compensates for the Pscan scan lines and the Nscan scan lines. For a display panel having an irregular display area 3 and a normal display area 4 with different pixel setting densities or pixel numbers, wherein the pixel setting density or pixel number of the irregular display area 3 is less than the pixel setting density or pixel number of the normal display area 4, the capacitance of the Pscan scan lines and the Nscan scan lines of the irregular display area 3 can be compensated so that the capacitance of the Pscan scan lines and the Nscan scan lines of the irregular display area 3 and the capacitance of the Pscan scan lines and the Nscan scan lines of the normal display area 4 tend to be the same, thereby reducing the capacitance difference of the Pscan scan lines and the Nscan scan lines in the irregular display area 3 and the normal display area 4, and reducing the risk of split screen between the irregular display area 3 and the normal display area 4 due to the capacitance difference of the Pscan scan lines and the Nscan scan lines.
