[0033] To make the purpose, technical solutions and effects of this application clearer and more specific, the following further describes this application in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain this application and are not intended to limit this application.

[0034] To address the technical issue of significant delay in the ending edge of a scan signal during forward or reverse scanning, this embodiment provides a display panel. Referring to Figures 1 to 15 , as shown in Figures 1 and 3 , the display panel includes a plurality of scan lines arranged sequentially along a first direction DR1, a waveform adjustment module 100, a potential transmission line VL, a forward scan control line U2D, and a reverse scan control line D2U. The plurality of scan lines include the N-1th scan line G(N-1), the Nth scan line G(N), and the N+1th scan line G(N+1), where N is an integer greater than or equal to 2. The output terminal of the waveform adjustment module 100 is electrically connected to the N+1th scan line G(N+1), the first control terminal of the waveform adjustment module 100 is electrically connected to the N-1th scan line G(N-1), and the second control terminal of the waveform adjustment module 100 is electrically connected to the N+1th scan line G(N+1). The waveform adjustment module 100 is located in the display area AA of the display panel. The potential transmission line VL is electrically connected to the first input terminal of the waveform adjustment module 100. The forward scan control line U2D is electrically connected to the second input terminal of the waveform adjustment module 100 or the third control terminal of the waveform adjustment module 100. The reverse scan control line D2U is electrically connected to the third input terminal of the waveform adjustment module 100 or the fourth control terminal of the waveform adjustment module 100.

[0035] It can be understood that the display panel provided in this embodiment can reduce the duration of the end edge of the scanning signal during the forward scan or reverse scan process through the control of the waveform adjustment module 100 by the N-1th scanning line G(N-1), the N+1th scanning line G(N+1), the potential transmission line VL, the forward scanning control line U2D and the reverse scanning control line D2U, thereby improving the technical problem of the large delay of the scanning signal in the display panel; this is conducive to increasing the charging time of each pixel in the display panel or increasing the refresh frequency of the display panel, and thus is conducive to promoting the development of high-frequency display and / or high resolution of the display panel.

[0036] Furthermore, the display panel and the display device can improve the delay problem of the scanning signal during forward scanning, and can also improve the delay problem of the scanning signal during reverse scanning, thereby providing greater freedom for the assembly of the display panel.

[0037] It should be noted that the first direction DR1 may be an arrangement direction of a plurality of scan lines, and the second direction DR2 may be an extension direction of each scan line.

[0038] Among them, the reverse scan control line D2U, the potential transmission line VL and the forward scan control line U2D electrically connected to the same waveform adjustment module 100 can be arranged in sequence along the second direction DR2, which is beneficial to reducing the transmission distance between the reverse scan control line D2U, the potential transmission line VL and the forward scan control line U2D and the waveform adjustment module 100.

[0039] The display panel may further include a plurality of data lines arranged sequentially along a second direction DR2, such as a first data line datar, a second data line datag, and a third data line datab. Each scan line intersects with each data line to form an array of sub-pixels 200. The first data line datar may be electrically connected to a column of red sub-pixels 200 (R). The second data line datag may be electrically connected to a column of green sub-pixels 200 (G). The third data line datab may be electrically connected to a column of blue sub-pixels 200 (B).

[0040] Specifically, the reverse scan control line D2U is adjacent to and parallel to the first data line datar, and the reverse scan control line D2U is located on the left side of the first data line datar. The potential transmission line VL is adjacent to and parallel to the second data line datag, and the potential transmission line VL is located on the left side of the second data line datag. The forward scan control line U2D is adjacent to and parallel to the third data line datab, and the forward scan control line U2D is located on the left side of the third data line datab. This can reduce the loss of the pixel aperture ratio. As shown in Figure 3, when there is no adjacent and parallel reverse scan control line D2U, potential transmission line VL and forward scan control line U2D on the left side of the corresponding data line, the display panel will also configure a virtual line Dummy adjacent to and parallel to the corresponding data line to balance the consistent coupling effect on each data line.

[0041] Among them, each sub-pixel 200 can be a sub-pixel of passive display, such as a sub-pixel using liquid crystal display. In this case, each sub-pixel 200 can include a thin film transistor, one of the drain or source of the thin film transistor is connected to the corresponding data line, the other of the drain or source of the thin film transistor is connected to the common voltage line con, and the gate of the thin film transistor is connected to the corresponding scan line.

[0042] In one embodiment, as shown in Figure 2, the waveform adjustment module 100 includes a first transistor NTA, a second transistor NTB and a third transistor NTC. The first electrode of the first transistor NTA is electrically connected to the reverse scan control line D2U, and the gate of the first transistor NTA is electrically connected to the N-1th scan line G(N-1); the first electrode of the second transistor NTB is electrically connected to the forward scan control line U2D, and the gate of the second transistor NTB is electrically connected to the N+1th scan line G(N+1); the gate of the third transistor NTC is electrically connected to the second electrode of the first transistor NTA and the second electrode of the second transistor NTB, the first electrode of the third transistor NTC is electrically connected to the potential transmission line VL, and the second electrode of the third transistor NTC is electrically connected to the Nth scan line G(N).

[0043] It should be noted that the first electrode can be either a source or a drain, and the second electrode can be the other of the source or the drain. For example, when the first electrode is a source, the second electrode is a drain; or when the first electrode is a drain, the second electrode is a source.

[0044] During the forward scan process, when the N+1th scan line G(N+1) controls the second transistor NTB to turn on, the forward scan control line U2D also controls the third transistor NTC to turn on. At this time, the potential in the Nth scan line G(N) is adjusted to the potential of the potential transmission line VL.

[0045] During the reverse scan process, when the N-1th scan line G(N-1) controls the first transistor NTA to turn on, the reverse scan control line D2U also controls the third transistor NTC to turn on. At this time, the potential in the Nth scan line G(N) is also adjusted to the potential of the potential transmission line VL.

[0046] In this way, the verticality of the ending edge of the N-th level scanning signal in the N-th scanning line G(N) can be improved during the forward scanning process, and the verticality of the ending edge of the N-th level scanning signal in the N-th scanning line G(N) can be improved during the reverse scanning process. The ending edge of a positive pulse refers to the falling edge of the pulse, and the ending edge of a negative pulse refers to the rising edge of the pulse.

[0047] In one embodiment, the first transistor NTA, the second transistor NTB and the third transistor NTC are all N-channel thin film transistors; the potential transmission line VL is used to transmit a low potential signal, which is used to control the N-channel thin film transistors to be in a cut-off state.

[0048] It should be noted that when the scanning signals transmitted in each scanning line have positive pulses, this embodiment can make the positive pulses of each scanning signal have a steeper or vertical falling edge to be closer to the ideal waveform of the pulse.

[0049] In one embodiment, the first transistor NTA and the second transistor NTB are both P-channel thin film transistors, and the third transistor NTC is an N-channel thin film transistor; the potential transmission line VL is used to transmit a high potential signal, and the high potential signal is used to control the P-channel thin film transistor to be in a cut-off state.

[0050] It should be noted that when the scanning signals transmitted in each scanning line have a negative pulse, this embodiment can make the negative pulse of each scanning signal have a steeper or vertical rising edge to be closer to the ideal waveform of the pulse.

[0051] In one embodiment, as shown in FIG4 , the waveform adjustment module 100 includes a fourth transistor T1, a fifth transistor T2, a sixth transistor T3, and a seventh transistor T4. A first electrode of the fourth transistor T1 is electrically connected to the potential transmission line VL, and a gate of the fourth transistor T1 is electrically connected to the forward scan control line U2D; a first electrode of the fifth transistor T2 is electrically connected to the second electrode of the fourth transistor T1, a gate of the fifth transistor T2 is electrically connected to the N+1th scan line G(N+1), and a second electrode of the fifth transistor T2 is electrically connected to the Nth scan line G(N); a first electrode of the sixth transistor T3 is electrically connected to the first electrode of the fourth transistor T1, and a gate of the sixth transistor T3 is electrically connected to the reverse scan control line D2U; a first electrode of the seventh transistor T4 is electrically connected to the second electrode of the sixth transistor T3, a gate of the seventh transistor T4 is electrically connected to the N-1th scan line G(N-1), and a second electrode of the seventh transistor T4 is electrically connected to the Nth scan line G(N).

[0052] It should be noted that, during the forward scanning process, the forward scanning line controls the fourth transistor T1 to be in the on state. When the N+1th scanning line G(N+1) controls the fifth transistor T2 to be turned on, the potential in the Nth scanning line G(N) is adjusted to the potential of the potential transmission line VL.

[0053] During the reverse scanning process, the reverse scanning line controls the sixth transistor T3 to be in the on state. When the N-1th scanning line G(N-1) controls the seventh transistor T4 to be turned on, the potential in the Nth scanning line G(N) is adjusted to the potential of the potential transmission line VL.

[0054] It can be understood that this can improve the verticality of the ending edge of the N-th level scanning signal in the N-th scanning line G (N) during the forward scanning process, and can also improve the verticality of the ending edge of the N-th level scanning signal in the N-th scanning line G (N) during the reverse scanning process.

[0055] In one embodiment, the fourth transistor T1, the fifth transistor T2, the sixth transistor T3 and the seventh transistor T4 are all N-channel thin film transistors; the potential transmission line VL is used to transmit a low potential signal, which is used to control the N-channel thin film transistors to be in an off state.

[0056] It should be noted that when the scanning signals transmitted in each scanning line have positive pulses, this embodiment can make the positive pulses of each scanning signal have a steeper or vertical falling edge to be closer to the ideal waveform of the pulse.

[0057] In one embodiment, the fourth transistor T1 and the sixth transistor T3 are both N-channel thin film transistors, and the fifth transistor T2 and the seventh transistor T4 are both P-channel thin film transistors; the potential transmission line VL is used to transmit a high potential signal, and the high potential signal is used to control the P-channel thin film transistor to be in an off state.

[0058] It should be noted that when the scanning signals transmitted in each scanning line have a negative pulse, this embodiment can make the negative pulse of each scanning signal have a steeper or vertical rising edge to be closer to the ideal waveform of the pulse.

[0059] Figure 5 is a schematic comparison of the improved non-irregular display panel provided by an embodiment of the present application before and after improvement. The non-irregular display panel may include, but is not limited to, a display panel having a rectangular display area AA. Specifically, the display area AA can be divided into four regions: Region A, Region B, Region C, and Region D. Regions A and B are located near the first gate driver circuit GOA1 and the second gate driver circuit GOA2 and are symmetrical about the center of the display area AA. Regions C and D are located away from the first gate driver circuit GOA1 and the second gate driver circuit GOA2 and are symmetrical about the center of the display area AA. To improve the delay of the trailing edge of the scan signal in the display area AA, a corresponding number of waveform adjustment modules 100 are placed in Regions A, B, C, and D, respectively. In Regions A and B, one waveform adjustment module 100 is configured for every M sub-pixels 200, and in Regions C and D, one waveform adjustment module 100 is configured for every N sub-pixels 200, where M and N are integers, and M is less than or equal to N.

[0060] Before the waveform adjustment module 100 is configured in the display area AA, the falling edges of the corresponding scanning signals in areas A, B, C, and D are shown in a row of waveforms corresponding to "ultra-wide screen" in FIG5 . It can be seen that the delay of each falling edge is relatively large.

[0061] After the waveform adjustment module 100 is configured in the display area AA, the falling edges of the corresponding scanning signals in areas A, B, C, and D are shown in a row of waveforms corresponding to the "ultra-wide screen + waveform adjustment module" in Figure 5. It can be seen that the delay of each falling edge is small, and each falling edge is also steeper or vertical.

[0062] The IC is a data driver or a data driver chip, which can provide corresponding data signals for each data line.

[0063] 6 , 7 , 8 and 9 respectively show a form of a special-shaped display panel. Compared with FIG. 5 , the display areas AA shown in FIG. 6 to FIG. 9 are all non-rectangular areas.

[0064] For example, the display area AA shown in Figure 6 has its lower left corner hollowed out. In this case, the first gate drive circuit GOA1 provides corresponding scan signals for each scan line from the right side, the second gate drive circuit GOA2 provides corresponding scan signals for each scan line in the normal display area AA domain from the left side, and the third gate drive circuit GOA3 provides corresponding scan signals for each scan line in the special-shaped display area AA domain from the left side.

[0065] The bottom edge area of ​​the display area AA shown in FIG7 is hollowed out. In this case, the first gate driving circuit GOA1 provides corresponding scanning signals to each scanning line from the right side, and the second gate driving circuit GOA2 provides corresponding scanning signals to each scanning line from the left side.

[0066] The display area AA shown in FIG8 has its center area hollowed out. In this case, the first gate driving circuit GOA1 provides corresponding scanning signals to each scanning line from the right side, and the second gate driving circuit GOA2 provides corresponding scanning signals to each scanning line from the left side.

[0067] The display area AA shown in Figure 9 has its left edge area hollowed out. In this case, the first gate drive circuit GOA1 provides corresponding scan signals to each scan line from the right side, the second gate drive circuit GOA2 provides corresponding scan signals to each scan line in the upper part from the left side, the third gate drive circuit GOA3 provides corresponding scan signals to each scan line in the middle part from the left side, and the fourth gate drive circuit GOA4 provides corresponding scan signals to each scan line in the lower part from the left side.

[0068] In one embodiment, as shown in Figures 8 to 15, the display panel includes a waveform adjustment module 100 configured to improve the ending edge of the scanning signal in the display area AA, the display area AA includes a first display partition AA1 and a second display partition AA2 arranged in a first direction DR1, the second display partition AA2 is located within the projection of the first display partition AA1 in the first direction DR1, and the second display partition AA2 covers the portion of the projection of the first display partition AA1 in the first direction DR1.

[0069] A first gate driving circuit GOA1 and a second gate driving circuit GOA2 are respectively provided on both sides of the first display area AA1 . Each scan line in the first display area AA1 is electrically connected to the first gate driving circuit GOA1 and the second gate driving circuit GOA2 .

[0070] One or two of the first gate drive circuit GOA1, the second gate drive circuit GOA2, the third gate drive circuit GOA3 and the fourth gate drive circuit GOA4 are provided on both sides of the second display partition AA2, and each scan line in the second display partition AA2 is electrically connected to one or two of the first gate drive circuit GOA1, the second gate drive circuit GOA2, the third gate drive circuit GOA3 and the fourth gate drive circuit GOA4.

[0071] The first display area AA1 includes a plurality of first display sub-areas sequentially arranged along the second direction DR2 . The density of the waveform adjustment module 100 in each first display sub-area increases as the distance from the first gate driving circuit GOA1 and the second gate driving circuit GOA2 increases.

[0072] The second display area AA2 includes multiple second display sub-areas arranged in sequence along the second direction DR2, and the density of the waveform adjustment module 100 in each second display sub-area increases as the distance from one or two of the first gate drive circuit GOA1, the second gate drive circuit GOA2, the third gate drive circuit GOA3 and the fourth gate drive circuit GOA4 increases.

[0073] It can be understood that the display panel provided in this embodiment, by constructing differentiated densities of the waveform adjustment module 100 in each display partition with different gate drive circuit configurations, can not only improve the technical problem of large delay of the scanning signal in the display panel, but also enable the scanning signal to have the same or similar delay at different positions in the display area AA, which is beneficial to improving the uniformity of the display.

[0074] It should be noted that the density of the waveform adjustment module 100 in each first display sub-area increases as the distance from the first gate drive circuit GOA1 and the second gate drive circuit GOA2 increases, and the density of the waveform adjustment module 100 in each second display sub-area increases as the distance from one or two of the first gate drive circuit GOA1, the second gate drive circuit GOA2, the third gate drive circuit GOA3 and the fourth gate drive circuit GOA4 increases. Such a density arrangement of the waveform adjustment module 100 is conducive to achieving the same end edge delay of the scanning signal at different positions in the display area AA, and thus is conducive to achieving a uniform display effect in the display area AA.

[0075] In one embodiment, as shown in Figures 10 and 11, the first side of the first display partition AA1 is aligned with the first side of the second display partition AA2 in the first direction DR1, the second side of the first display partition AA1 is not aligned with the second side of the second display partition AA2 in the first direction DR1, and the first side and the second side are respectively located on both sides of the display area AA in the second direction DR2.

[0076] The first gate driving circuit GOA1 is located at the second side of the first display partition AA1 , the second gate driving circuit GOA2 is located at the first side of the first display partition AA1 , and the third gate driving circuit GOA3 is located at the first side of the second display partition AA2 .

[0077] The first density change rate of the waveform adjustment module 100 in the plurality of second display sub-areas is greater than the second density change rate, and the second density change rate is the density change rate of the waveform adjustment module 100 in the plurality of first display sub-areas.

[0078] It should be noted that the multiple first display sub-areas may be display sub-area A AA11, display sub-area B AA12, display sub-area C AA13, display sub-area D AA14, display sub-area C AA15, etc. The multiple second display sub-areas may be display sub-area B AA21, display sub-area D AA22, display sub-area D AA23, display sub-area C AA24, etc.

[0079] In particular, display sub-area AA11, display sub-area AA15, and display sub-area AA21 each have one waveform adjustment module 100 configured for H sub-pixels 200. Display sub-area AA12, display sub-area AA14, and display sub-area AA22 each have one waveform adjustment module 100 configured for J sub-pixels 200. Display sub-area AA13 has one waveform adjustment module 100 configured for K sub-pixels 200, where H, J, and K are integers and decrease in magnitude. Display sub-area AA23 has one waveform adjustment module 100 configured for K1 sub-pixels 200, and display sub-area AA24 has one waveform adjustment module 100 configured for J1 sub-pixels 200, where J1 and K1 are integers and J1 is greater than K1.

[0080] It is understandable that such a configuration can achieve the same end edge delay of the scanning signal at different positions in the display area AA, thereby facilitating uniform display effects in the display area AA.

[0081] In other embodiments, K1 may be greater than K, and J1 may be greater than J. Such a configuration can further achieve the same end edge delay of the scanning signal at different positions in the display area AA, thereby further facilitating the uniformity of the display effect in the display area AA.

[0105] It can be understood that the display device provided in this embodiment, by constructing differentiated densities of the waveform adjustment module 100 in each display partition with different gate drive circuit configurations, can not only improve the technical problem of large delay of the scanning signal in the display panel, but also enable the scanning signal to have the same or similar delay at different positions in the display area AA, which is beneficial to improving the uniformity of the display.

[0106] It can be understood that since the display device provided in this embodiment includes the display panel of at least one of the above-mentioned embodiments, it can also control the waveform adjustment module 100 through the N-1th scan line G (N-1), the N+1th scan line G (N+1), the potential transmission line VL, the forward scan control line U2D and the reverse scan control line D2U, and can reduce the duration of the end edge of the scan signal during the forward scan or reverse scan process, thereby improving the technical problem of the large delay of the scan signal in the display panel; this is conducive to increasing the charging time of each pixel in the display panel or increasing the refresh frequency of the display panel, and thus is conducive to promoting the development of high-frequency display and / or high resolution of the display panel.

[0107] Furthermore, the display panel and the display device can improve the delay problem of the scanning signal during forward scanning, and can also improve the delay problem of the scanning signal during reverse scanning, thereby providing greater freedom for the assembly of the display panel.

[0108] It should be noted that the above-mentioned display panel can be a liquid crystal display panel or a self-luminous display panel, for example, an organic light emitting diode display panel, a mini light emitting diode display panel, a micro light emitting diode display panel or a quantum dot light emitting diode display panel.

[0109] Based on the above analysis, this embodiment further provides a display panel, please refer to Figures 1 to 18, the display panel includes multiple waveform adjustment modules 100 in the display area AA, and at least one gate drive circuit is arranged on both sides of the display area AA. The distribution density of the waveform adjustment module 100 in the area away from the gate drive circuit is greater than the distribution density of the waveform adjustment module 100 in the area close to the gate drive circuit.

[0110] It can be understood that the display panel provided in this embodiment, by constructing a waveform adjustment module 100 with a higher distribution density in the display area AA which is farther away from the gate driving circuit, can not only improve the technical problem of large delay of the scanning signal in the display panel, but also enable the scanning signal to have the same or similar delay at different positions in the display area AA, which is beneficial to improving the uniformity of the display.

[0111] It should be noted that the distribution density refers to the ratio of the number of waveform adjustment modules 100 in a certain area to the area of ​​the area.

[0112] In one embodiment, the display area AA includes a first display partition AA1 and a second display partition AA2, the effective display width of the first display partition AA1 is greater than the effective display width of the second display partition AA2; the first display partition AA1 includes multiple first sub-areas AA19; the second display partition AA2 includes multiple second sub-areas AA29.

[0113] It should be noted that the effective display width refers to the width of the area of ​​the display panel that can be used for display. Each first sub-area AA19 can be used for display and is arranged continuously in the direction of the effective display width. Multiple second sub-areas AA29 can be arranged continuously or discontinuously in the direction of the effective display width.

[0114] The waveform adjustment modules 100 have the same distribution density in different areas of the same first sub-area AA19 or the second sub-area AA29 , that is, the waveform adjustment modules 100 are evenly distributed in the same first sub-area AA19 or the second sub-area AA29 .

[0115] In one embodiment, as shown in FIG8 , gate drive circuits are respectively provided on both sides of the display area AA, and the width of the first display partition AA1 from left to right is consistent with the width of the second display partition AA2 from left to right; the distribution density of the waveform adjustment module 100 in the first sub-area AA19 farthest from the gate drive circuit is greater than the distribution density of the waveform adjustment module 100 in the second sub-area AA29 farthest from the gate drive circuit.

[0116] It should be noted that the hollowed-out area in FIG. 8 may also serve as a second sub-area AA29 . In this case, the distribution density of the waveform adjustment module 100 in the hollowed-out area may be zero.

[0117] In one embodiment, as shown in Figures 10 and 11, gate driving circuits are respectively provided on both sides of the first display area AA1, and a gate driving circuit is provided on one of the two sides of the second display area AA2; the distribution density of the waveform adjustment module 100 in the first sub-area AA19 farthest from the gate driving circuit is less than the distribution density of the waveform adjustment module 100 in the second sub-area AA29 farthest from the gate driving circuit.

[0118] It should be noted that the farther the area is from the gate drive circuit, the more serious the delay of the scanning signal is. Therefore, configuring a waveform adjustment module 100 with a larger distribution density can better correct the delay of the scanning signal and better adjust the waveform of the scanning signal in the display area AA to be consistent.

[0119] In one embodiment, the difference between the distribution density of the waveform adjustment module 100 in the first sub-area AA19 away from the gate driving circuit and the distribution density in the first sub-area AA19 close to the gate driving circuit is a first difference, and the difference between the distribution density of the waveform adjustment module 100 in the second sub-area AA29 away from the gate driving circuit and the distribution density in the second sub-area AA29 close to the gate driving circuit is a second difference, and the first difference is greater than the second difference.

[0120] It should be noted that, since the effective display widths of the first display partition AA1 and the second display partition AA2 are inconsistent, this embodiment can make the delay of the scan signal in the first display partition AA1 and the second display partition AA2 more consistent, which is beneficial to improving display uniformity.

[0121] In one embodiment, as shown in Figures 16 to 18, the display panel further includes a scan line, a forward scan control line U2D, a reverse scan control line D2U, and a potential transmission line VL electrically connected to the waveform adjustment module 100, the scan line extends from the gate drive circuit to the display area AA, and at least one of the forward scan control line U2D, the reverse scan control line D2U, and the potential transmission line VL extends from a non-display area on a different side from the gate drive circuit to the display area AA.

[0122] It should be noted that the non-display area may include at least one of the left frame area NA1, the right frame area NA2, the upper frame area NA3, and the lower frame area NA4. Each gate drive circuit may be located in the left frame area NA1 and / or the frame area. In this embodiment, at least one of the forward scan control line U2D, the reverse scan control line D2U, and the potential transmission line VL extends from the upper frame area NA3 and / or the lower frame area NA4 to the display area AA, which can avoid affecting the original distribution of the scan lines. Among them, at least one of the forward scan control line U2D, the reverse scan control line D2U, and the potential transmission line VL can extend at least partially around the display area AA in the non-display area.

[0123] In one embodiment, as shown in Figure 16, in the same width range WF, the distribution density of the waveform adjustment module 100 in the first sub-area AA19 is greater than the distribution density of the waveform adjustment module 100 in the second sub-area AA29; the display panel also includes a forward scan control supplementary line 41, a reverse scan control supplementary line 43 and a potential transmission supplementary line 42 electrically connected to the waveform adjustment module 100, and at least one of the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 extends from a non-display area on a different side from the gate drive circuit and close to the first display partition AA1 to the corresponding first sub-area AA19.

[0124] It should be noted that when the distribution density of the waveform adjustment module 100 in the first sub-area AA19 is large enough, the number of the forward scan control line U2D, the reverse scan control line D2U and the potential transmission line VL fixedly configured in the display panel will not be able to meet the demand, which requires the addition of the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 to respectively make up for the insufficient number of the forward scan control line U2D, the reverse scan control line D2U and the potential transmission line VL.

[0125] In this embodiment, the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 can extend from the upper frame area NA3 to the corresponding first sub-area AA19, which not only reduces the transmission path of the corresponding signal, but also does not affect the second display area AA2.

[0126] In one embodiment, as shown in Figure 17, in the same width range WF, the distribution density of the waveform adjustment module 100 in the first sub-area AA19 is less than the distribution density of the waveform adjustment module 100 in the second sub-area AA29; the display panel also includes a forward scan control supplementary line 41, a reverse scan control supplementary line 43 and a potential transmission supplementary line 42 electrically connected to the waveform adjustment module 100, and at least one of the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 extends from a non-display area on a different side from the gate drive circuit and close to the second display partition AA2 to the corresponding first sub-area AA19.

[0127] It should be noted that when the distribution density of the waveform adjustment module 100 in the second sub-area AA29 is large enough, the number of the forward scan control line U2D, the reverse scan control line D2U and the potential transmission line VL fixed in the display panel will not be able to meet the demand, which requires the addition of the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 to respectively make up for the insufficient number of the forward scan control line U2D, the reverse scan control line D2U and the potential transmission line VL.

[0128] In this embodiment, the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 can extend from the lower frame area NA4 to the corresponding second sub-area AA29, which not only reduces the transmission path of the corresponding signal, but also does not affect the first display area AA1.

[0129] In one embodiment, as shown in Figures 9 and 18, the second display partition AA2 is located between the two first display partitions AA1; in the same width range WF, the distribution density of the waveform adjustment module 100 in the first sub-area AA19 is less than the distribution density of the waveform adjustment module 100 in the second sub-area AA29; the display panel also includes a forward scan control supplementary line 41, a reverse scan control supplementary line 43 and a potential transmission supplementary line 42 electrically connected to the waveform adjustment module 100, and at least one of the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 extends from a non-display area on a different side from the gate drive circuit and close to the first display partition AA1 through the first display partition AA1 to the corresponding second sub-area AA29; wherein, the number of branches of at least one of the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 in the first display partition AA1 is less than the number of branches in the second display partition AA2.

[0130] It should be noted that when the distribution density of the waveform adjustment module 100 in the second sub-area AA29 is large enough, the number of the forward scan control line U2D, the reverse scan control line D2U and the potential transmission line VL fixed in the display panel will not be able to meet the demand, which requires the addition of the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 to respectively make up for the insufficient number of the forward scan control line U2D, the reverse scan control line D2U and the potential transmission line VL.

[0131] However, since the forward scan control supplementary line 41, the reverse scan control supplementary line 43 and the potential transmission supplementary line 42 are not convenient to extend from the left border area NA1 and / or the right border area NA2 to the second display partition AA2, in this case, they can only extend from the upper border area NA3 and / or the lower border area NA4 through the first display partition AA1 to the corresponding second sub-area AA29. In this embodiment, the forward scan control supplementary line 41 / reverse scan control supplementary line 43 / potential transmission supplementary line 42 is divided from a branch in the first display partition AA1 into multiple branches in the second display partition AA2, which can minimize the impact on the first display partition AA1 and meet the requirements of the corresponding second sub-area AA29.

[0132] In another embodiment, different waveform adjustment modules 100 in the second sub-area AA29 may share at least one of the forward scan control line U2D, the reverse scan control line D2U, and the potential transmission line VL, which can also meet the needs of more waveform adjustment modules 100.

[0133] It should be noted that the display panels shown in FIG. 16 to FIG. 18 can be either rectangular display screens or various special-shaped screens, for example, the display screens with hollowed-out areas or missing corners as described above.

[0134] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this application, and all these changes or substitutions should fall within the scope of protection of the claims attached to this application.
