Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display device and a driving method thereof. Background Art

[0002] With the development of display technology, liquid crystal display (LCD) panels and organic light emitting diode (OLED) display panels have gradually become the two mainstream display panels in the display field. LCD panels and OLED display panels are widely used in computers, mobile phones, wearable devices, automotive and other devices (including display devices) or scenes that can integrate display functions that are known to technicians in this field.

[0003] Usually, the operation of electronic products will cause interference to other electronic products around them. This interference can be called electromagnetic interference (EMI). The performance of electronic products affected by electromagnetic interference is reduced or even cannot work properly. Based on this, when the display device is integrated into certain equipment or applied to certain scenarios, such as applying the display device to a car display and using it as a car display, the display device will cause electromagnetic interference to other electronic products on the car. Summary of the invention

[0004] The present invention provides a display device and a driving method thereof, which destroy the inherent frequency characteristics of a scanning signal, thereby weakening the electromagnetic interference energy caused by the inherent frequency, and avoiding interference of the electromagnetic interference energy to other electronic products.

[0005] In a first aspect, an embodiment of the present invention provides a display device, comprising a plurality of scan lines and at least one first driving circuit, wherein the plurality of scan lines are arranged in sequence, the first driving circuit is electrically connected to the plurality of scan lines and is configured to provide a scan signal to the scan line, wherein the scan signal comprises a scan enable segment;

[0006] In the same scanning frame of the display phase, there is a scanning gap between the scanning enable segments on two adjacent scanning lines, the scanning enable segments on at least two scanning lines have different widths, and all the scanning gaps have the same width.

[0007] In a second aspect, an embodiment of the present invention provides a driving method of the display device according to the first aspect, comprising:

[0008] In the same scanning frame of the display phase, there is a scanning gap between the scanning enable segments on two adjacent scanning lines, the scanning enable segments on at least two scanning lines have different widths, and all the scanning gaps have the same width.

Therefore, by setting the durations of at least two scanning enable segments in the same scanning frame to be unequal, the inherent frequency characteristics of the scanning signal are destroyed, and the electromagnetic interference energy caused by the inherent frequency can be weakened, thereby avoiding the electromagnetic interference energy from interfering with other electronic products.

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] Figure 1 A schematic diagram of a top view of a display device provided by an embodiment of the present invention is shown in FIG. Figure 2 A driving timing diagram of a display device provided by an embodiment of the present invention, referring to Figure 1 and Figure 2 The display device includes a plurality of scan lines 21 and at least one first drive circuit 30. The plurality of scan lines 21 are arranged in sequence. The first drive circuit 30 is electrically connected to the plurality of scan lines 21. The first drive circuit 30 is configured to provide a scan signal to the scan line 21. The scan signal includes a scan enable segment EN1. In the same scan frame of the display stage, there is a scan gap Gap1 between the scan enable segments EN1 on two adjacent scan lines 21. The scan enable segments EN1 on at least two scan lines 21 have different widths, and all scan gaps Gap1 have the same width. In the same scan frame of the display stage, the first drive circuit 30 sequentially drives the plurality of scan lines 21 to sequentially turn on the pixel drive transistors 23 electrically connected to the scan lines 21.

[0025] For example, reference Figure 1 and Figure 2 The display device includes two first drive circuits 30, and the two first drive circuits 30 are respectively a first sub-drive circuit 31 and a second sub-drive circuit 32. A plurality of scan lines 21 extend along the first direction and are arranged along the second direction. Along the second direction, the plurality of scan lines 21 are sequentially recorded as the first scan line Gate1, the second scan line Gate2, the third scan line Gate3, the fourth scan line Gate4, and so on, until the last scan line Gateh, where h is a positive integer greater than 1. The scan enable segment EN1 on the first scan line Gate1 has a first scan enable width W1, and the scan enable segment EN1 on the second scan line Gate2 has a second scan enable width W2, and the first scan enable width W1 is not equal to the second scan enable width W2.

[0026] In the display device provided by the embodiment of the present invention, in the same scanning frame of the display stage, there is a scanning gap Gap1 between the scanning enable segments EN1 on two adjacent scanning lines 21, the scanning enable segments EN1 on at least two scanning lines 21 have different widths, and all scanning gaps Gap1 have the same width. Therefore, by setting the durations of at least two scanning enable segments EN1 in the same scanning frame to be unequal, the inherent frequency characteristics of the scanning signal are destroyed, and the electromagnetic interference energy caused by the inherent frequency can be weakened, thereby avoiding the electromagnetic interference energy from interfering with other electronic products.

[0027] Optionally, refer to Figure 1 and Figure 2 , M adjacent scan lines 21 constitute a scan line group Z, and the multiple scan lines 21 include multiple scan line groups Z. In the same scan frame of the display stage, in the same scan line group Z, the scan enable segments EN1 on any two scan lines 21 have different widths. In the same scan frame of the display stage, the scan enable segment EN1 on the i-th scan line 21 has the same width as the scan enable segment EN1 on the i+M-th scan line 21. Wherein, i and M are both positive integers, and M≥2, i≥1. In an embodiment of the present invention, M adjacent scan lines 21 constitute a scan line group Z, and the durations of the scan enable segments EN1 in the same scan line group Z are not equal, thereby destroying the inherent frequency characteristics of the scan signal. There are scan enable segments EN1 of the same width in different scan line groups Z, thereby reducing the design requirements of the first drive circuit 30.

[0028] For example, reference Figure 1 and Figure 2, taking M=2 as an example, two adjacent scan lines 21 constitute a scan line group Z, the first scan line Gate1 and the second scan line Gate2 constitute a scan line group Z, and the third scan line Gate3 and the fourth scan line Gate4 constitute another scan line group Z. In the same scan frame of the display stage, the scan enable segment EN1 on the first scan line Gate1 has a first scan enable width W1, and the scan enable segment EN1 on the second scan line Gate2 has a second scan enable width W2, and the first scan enable width W1 is not equal to the second scan enable width W2. Similarly, in the same scan frame of the display stage, the scan enable segment EN1 on the third scan line Gate3 has a first scan enable width W1, and the scan enable segment EN1 on the fourth scan line Gate4 has a second scan enable width W2, and the first scan enable width W1 is not equal to the second scan enable width W2. In the same scanning frame of the display stage, the scan enable segment EN1 on the first scan line Gate1 and the scan enable segment EN1 on the third scan line Gate3 have the same width, and the scan enable segment EN1 on the second scan line Gate2 and the scan enable segment EN1 on the fourth scan line Gate4 have the same width.

[0029] Optionally, refer to Figure 1 The display device includes two first drive circuits 30, and the two first drive circuits 30 are respectively a first sub-drive circuit 31 and a second sub-drive circuit 32. The first sub-drive circuit 31 is electrically connected to the odd-numbered scan lines 21, and the second sub-drive circuit 32 is electrically connected to the even-numbered scan lines 21. In the embodiment of the present invention, the first sub-drive circuit 31 is electrically connected to the first, third, and other odd-numbered scan lines 21, and the second sub-drive circuit 32 is electrically connected to the second, fourth, and other even-numbered scan lines 21, so as to realize cross-driving of the scan lines 21 in the display device. In other embodiments, the scan lines 21 in the display device may also adopt other driving modes, which are not limited in the embodiment of the present invention.

[0030] For example, reference Figure 1 and Figure 2, the first sub-driving circuit 31 is electrically connected to the odd-numbered scan lines 21, the first sub-driving circuit 31 provides scan signals to the odd-numbered scan lines 21, and the scan enable segments EN1 on the odd-numbered scan lines 21 all have the first scan enable width W1. The second sub-driving circuit 32 is electrically connected to the even-numbered scan lines 21, the second sub-driving circuit 32 provides scan signals to the even-numbered scan lines 21, and the scan enable segments EN1 on the even-numbered scan lines 21 all have the second scan enable width W2. Therefore, in the implementation of the present invention, the first sub-driving circuit 31 only needs to provide a scan signal of the first scan enable width W1, and the second sub-driving circuit 32 only needs to provide a scan signal of the second scan enable width W2, which reduces the design requirements of the first sub-driving circuit 31 and the second sub-driving circuit 32.

[0031] Figure 3 A driving timing diagram of another display device provided by an embodiment of the present invention, Figure 2 The adjacent even-numbered scanning lines 21 constitute a scanning line group Z. The difference is that Figure 3 , adjacent odd-numbered scan lines 21 may also constitute a scan line group Z. Exemplarily, three adjacent scan lines 21 constitute a scan line group Z, and the first scan line Gate1, the second scan line Gate2, and the third scan line Gate3 constitute a scan line group Z. In the same scan frame of the display stage, the scan enable segment EN1 on the first scan line Gate1 has a first scan enable width W1, the scan enable segment EN1 on the second scan line Gate2 has a second scan enable width W2, and the scan enable segment EN1 on the third scan line Gate3 has a third scan enable width W3, and any two of the first scan enable width W1, the second scan enable width W2, and the third scan enable width W3 are not equal.

[0032] Figure 4 A schematic diagram of a top view of another display device provided in an embodiment of the present invention, referring to Figure 4 The display device includes two first driving circuits 30, and the two first driving circuits 30 are respectively a first sub-driving circuit 31 and a second sub-driving circuit 32. The first sub-driving circuit 31 and the second sub-driving circuit 32 are both electrically connected to the same scan line 21. In the embodiment of the present invention, the first sub-driving circuit 31 is electrically connected to all the scan lines 21, and the second sub-driving circuit 32 is electrically connected to all the scan lines 21, so as to realize bilateral driving of the scan lines 21 in the display device.

[0033] Figure 5 A schematic diagram of a top view of another display device provided in an embodiment of the present invention, referring to Figure 5 The display device includes a first driving circuit 30, which is electrically connected to all the scanning lines 21 to achieve unilateral driving of the scanning lines 21 in the display device.

[0034] It should be noted that when the scanning line 21 in the display device is driven unilaterally, bilaterally or crosswise, the following methods can be used: Figure 2 The driving timing shown may also adopt other driving timings, as long as in the same scanning frame of the display stage, the scanning enable segments EN1 on at least two scanning lines 21 have different widths and all the scanning gaps Gap1 have the same width.

[0035] Figure 6 Another driving timing diagram of a display device provided by an embodiment of the present invention is shown in FIG. Figure 6 , N adjacent scan lines 21 constitute a scan line group Z, and the multiple scan lines 21 include multiple scan line groups Z. In the same scan frame of the display stage, in the same scan line group Z, the scan enable segments EN1 on any two scan lines 21 have the same width. In the same scan frame of the display stage, there are at least two scan line groups Z, and the scan enable segments EN1 on the two scan lines 21 respectively located in the two scan line groups Z have different widths. Wherein, N is a positive integer, and N≥2. In the embodiment of the present invention, N adjacent scan lines 21 constitute a scan line group Z, and the duration of the scan enable segments EN1 in the same scan line group Z are all equal, thereby reducing the design requirements of the first driving circuit 30. There are at least two scan line groups Z, and the duration of the scan enable segments EN1 in the at least two scan line groups Z are not equal, thereby destroying the inherent frequency characteristics of the scan signal.

[0036] For example, reference Figure 6 , taking N=2 as an example, two adjacent scan lines 21 constitute a scan line group Z, the first scan line Gate1 and the second scan line Gate2 constitute a scan line group Z, and the third scan line Gate3 and the fourth scan line Gate4 constitute another scan line group Z. In the same scan frame of the display stage, the scan enable segment EN1 on the first scan line Gate1 has a first scan enable width W1, and the scan enable segment EN1 on the second scan line Gate2 has the first scan enable width W1. The scan enable segment EN1 on the third scan line Gate3 has a second scan enable width W2, and the scan enable segment EN1 on the fourth scan line Gate4 has a second scan enable width W2. The first scan enable width W1 is not equal to the second scan enable width W2.

[0037] For example, reference Figure 6 , adjacent even-numbered scan lines 21 constitute a scan line group Z. In other implementations, adjacent odd-numbered scan lines 21 may also constitute a scan line group Z.

[0038] Figure 7 A schematic diagram of a top view of another display device provided in an embodiment of the present invention, referring to Figure 6 and Figure 7 , the first driving circuit includes a plurality of cascaded shift registers 50, and the output end of the shift register 50 is electrically connected to the scan line 21. The first driving circuit 30 includes a first partition 301 and a second partition 302, and the input ends of the plurality of shift registers 50 in the first partition 301 are electrically connected to the first clock control line CK1, and the input ends of the plurality of shift registers 50 in the second partition 302 are electrically connected to the second clock control line CK2. In the same scanning frame of the display stage, in the same scanning line group Z, the scan enable segments EN1 on any two scan lines 21 have the same width, and there are at least two scanning line groups Z, and the scan enable segments EN1 on the two scan lines 21 in the two scanning line groups Z have different widths. In the embodiment of the present invention, the shift registers 50 in the first partition 301 of the first driving circuit 30 are driven by the first clock control line CK1, thereby driving the scan line 21 electrically connected to the shift registers 50 in the first partition 301. The shift register 50 in the second partition 302 of the first drive circuit 30 is driven by the second clock control line CK2, thereby driving the scan line 21 electrically connected to the shift register 50 in the second partition 302. Since the scan enable segments EN1 on any two scan lines 21 in the same scan line group Z have the same width, the scan lines 21 in the same scan line group Z can be electrically connected to the shift register 50 in the same partition (including the first partition 301 and the second partition 302), and at least two scan line groups Z with different scan enable widths (including the first scan enable width W1 and the second scan enable width W2) can be electrically connected to different partitions, respectively, reducing the design requirements of the first sub-drive circuit 31 and the second sub-drive circuit 32. In other embodiments, the first drive circuit 30 may also include at least three partitions, each of which includes a plurality of shift registers 50.

[0039] It should be noted that Figure 7 In the example, a first clock control line CK1 electrically connects multiple shift registers 50 in the first partition 301, and a second clock control line CK2 electrically connects multiple shift registers 50 in the second partition 302, but it is not limited to this sequence. In other embodiments, at least two first clock control lines CK1 electrically connect multiple shift registers 50 in the first partition 301, and at least two second clock control lines CK2 electrically connect multiple shift registers 50 in the second partition 302.

[0040] Exemplarily, in one embodiment, the first driving circuit 30 includes a first partition 301 and a second partition 302. Correspondingly, the display device includes two scan line groups Z, and each scan line group Z includes a plurality of scan lines 21. In the same scan line group Z, the scan enable segments EN1 on any two scan lines 21 have the same width, and the scan enable segments EN1 on the scan lines 21 in the two scan line groups Z have different widths. In the implementation of the present invention, the first partition 301 only needs to provide a scan signal with a scan enable width (e.g., the first scan enable width W1), and the second partition 302 only needs to provide a scan signal with another scan enable width (e.g., the second scan enable width W2), which reduces the design requirements of the first driving circuit 30.

[0041] Figure 8 A schematic diagram of a top view structure of a touch electrode layer provided in an embodiment of the present invention, referring to Figure 1 , Figure 2 and Figure 8 The display device further includes a touch electrode layer 60 and a driving chip 40. The touch electrode layer 60 is electrically connected to the driving chip 40. The touch electrode layer 60 is configured to receive a touch driving signal and generate a touch sensing signal to realize a touch function. The driving chip 40 is electrically connected to the first driving circuit 30. The driving chip 40 is configured to generate a touch driving signal and provide a clock control signal to the first driving circuit 30 according to the touch sensing signal. In the embodiment of the present invention, the touch electrode layer 60 and the first driving circuit 30 are both electrically connected to the driving chip 40. When the user touches the display device, the user continuously sends a touch command to the driving chip 40. The driving chip 40 can continuously change the control instruction (such as the clock control signal) sent to the first driving circuit 30 according to the touch command, thereby changing the width of the scan enable segment EN1 in the scan signal, so as to realize that the duration of at least two scan enable segments EN1 in the same scan frame is not equal. In other embodiments, the internal structure of the driving chip 40 can also be changed so that the driving chip 40 independently sends the clock control signal and independently sends the touch driving signal.

[0042] For example, reference Figure 8The touch electrode layer 60 includes a plurality of first touch electrodes 61 arranged in a matrix and a plurality of second touch electrodes 62 arranged in a matrix. Adjacent first touch electrodes 61 in the same matrix row are electrically connected, and adjacent second touch electrodes 62 in the same matrix column are electrically connected via a bridge 63. The direction of the matrix row is consistent with the first direction, and the direction of the matrix column is consistent with the second direction. The first touch electrode 61 and the second touch electrode 62 are in the same layer, and the first touch electrode 61 and the bridge 63 are in different layers. Among them, the first touch electrode 61 can be a touch drive electrode, and the second touch electrode 62 can be a touch sensing electrode; or, the first touch electrode 61 can be a touch sensing electrode, and the second touch electrode 62 can be a touch drive electrode. In other embodiments, the touch electrode layer 60 can also be a self-capacitive touch electrode layer, a different-layer mutual-capacitive touch electrode layer, or a resistive touch electrode layer, etc.

[0043] Fig. 9 A schematic diagram of a top view of another display device provided by an embodiment of the present invention, Fig.10 Another driving timing diagram of a display device provided by an embodiment of the present invention is shown in FIG. Figure 1 , Fig. 9 and Fig.10 The display device further includes a plurality of data lines 22, a second driving circuit 70, a plurality of switch control lines CKH and a driving chip 40. The plurality of data lines 22 intersect with the plurality of scan lines 21. The plurality of data lines 22 may extend along the second direction and be arranged along the first direction. The second driving circuit 70 is electrically connected to the plurality of data lines 22, and the second driving circuit 70 is configured to provide data signals to the data lines 22. The driving chip 40 is electrically connected to the first driving circuit 30, and the driving chip 40 is also electrically connected to the second driving circuit 70 through the switch control line CKH, and the driving chip 40 is configured to provide a switch control signal to the switch control line CKH, and the switch control signal includes a switch enable segment EN2. In the same scan enable segment EN1, there is a switch gap Gap2 between the switch enable segments EN2 on two adjacent switch control lines CKH. At least two switch enable segments EN2 have different widths, and / or at least two switch gaps Gap2 have different widths. The display device provided by the embodiment of the present invention, on the basis of the above embodiment, by setting the duration of at least two switch enable segments EN2 in the same scan enable segment EN1 to be unequal, or the duration of at least two switch gaps Gap2 to be unequal, or the duration of at least two switch enable segments EN2 to be unequal and the duration of at least two switch gaps Gap2 to be unequal, while the duration of at least two switch enable segments EN2 is unequal, the duration of at least two switch gaps Gap2 is unequal, thereby destroying the inherent frequency characteristics of the scan signal and the inherent frequency characteristics of the switch control signal, thereby further weakening the electromagnetic interference energy caused by the inherent frequency and avoiding interference of the electromagnetic interference energy to other electronic products.

[0044] Optionally, refer to Fig. 9 and Fig.10 In the same scan enable segment EN1, the switch enable segments EN2 on all the switch control lines CKH have the same width, and in at least two scan enable segments EN1, the two switch enable segments EN2 respectively located in the two scan enable segments EN1 have different widths. In the embodiment of the present invention, the switch enable segments EN2 on all the switch control lines CKH in the same scan enable segment EN1 have the same width, thereby reducing the design requirements of the second drive circuit 70. The switch enable segments EN2 with different widths in different scan enable segments EN1 destroy the inherent frequency characteristics of the switch control signal.

[0045] For example, reference Fig. 9 and Fig.10 , the display device includes three switch control lines CKH, namely, a first switch control line CKH1, a second switch control line CKH2, and a third switch control line CKH3. In the scan enable segment EN1 on the first scan line Gate1, the switch enable segments EN2 on the first switch control line CKH1, the second switch control line CKH2, and the third switch control line CKH3 all have a first switch enable width a. In the scan enable segment EN1 on the second scan line Gate2, the switch enable segments EN2 on the first switch control line CKH1, the second switch control line CKH2, and the third switch control line CKH3 all have a second switch enable width b. The first switch enable width a is not equal to the second switch enable width b.

[0046] For example, reference Fig. 9 and Fig.10 , in the scan enable segment EN1 on the first scan line Gate1, the switch gap Gap2 between the switch enable segment EN2 on the first switch control line CKH1 and the second switch control line CKH2 is recorded as the first switch gap G1, and the switch gap Gap2 between the switch enable segment EN2 on the second switch control line CKH2 and the third switch control line CKH3 is recorded as the second switch gap G2. The first switch gap G1 is not equal to the second switch gap G2. In the scan enable segment EN1 on the second scan line Gate2, the switch gap Gap2 between the switch enable segment EN2 on the first switch control line CKH1 and the second switch control line CKH2 is recorded as the third switch gap G3, and the switch gap Gap2 between the switch enable segment EN2 on the second switch control line CKH2 and the third switch control line CKH3 is recorded as the fourth switch gap G4. The third switch gap G3 is not equal to the fourth switch gap G4. Among them, the first switch gap G1 may be equal to the third switch gap G3, or the first switch gap G1 may not be equal to the third switch gap G3. The second switching gap G2 may be equal to the fourth switching gap G4, or the second switching gap G2 may not be equal to the fourth switching gap G4.

[0047] Optionally, refer to Fig.10 , a plurality of scan enable segments EN1 with different widths constitute a first repeating unit T1, and the widths of any two scan enable segments EN1 in the first repeating unit T1 are different, that is, a set consisting of a plurality of scan enable segments EN1 with different widths is used as the first repeating unit T1. A plurality of switch enable segments EN2 with different widths constitute a second repeating unit T2, and the widths of any two switch enable segments EN2 in the second repeating unit T2 are different, that is, a set consisting of a plurality of switch enable segments EN2 with different widths is used as the second repeating unit T2. The number of scan enable segments EN1 in the first repeating unit T1 is equal to the number of switch enable segments EN2 in the second repeating unit T2. In the embodiment of the present invention, the switch enable segments EN2 in the same scan enable segment EN1 width have the same width, the switch enable segments EN2 in different scan enable segment EN1 widths have different widths, and the number of types of widths of the scan enable segment EN1 is equal to the number of types of widths of the switch enable segment EN2. The width of the switch enable segment EN2 changes accordingly with the width of the scan enable segment EN1 , thereby simplifying the design difficulty of the first driving circuit 30 and the second driving circuit 70 .

[0048] For example, reference Fig.10 , the first repeating unit T1 includes a scan enable segment EN1 having a first scan enable width W1 and a scan enable segment EN1 having a second scan enable width W2. The second repeating unit T2 includes a switch enable segment EN2 having a first switch enable width a and a switch enable segment EN2 having a second switch enable width b. The number of the scan enable segments EN1 in the first repeating unit T1 is two, and the number of the switch enable segments EN2 in the second repeating unit T2 is also two. The switch enable segment EN2 having the first switch enable width a is arranged in the scan enable segment EN1 having the first scan enable width W1, and the switch enable segment EN2 having the second switch enable width b is arranged in the scan enable segment EN1 having the second scan enable width W2.

Fig.11, in the scan enable segment EN1 on the first scan line Gate1, the switch gap Gap2 between the first switch control line CKH1 and the switch enable segment EN2 on the second switch control line CKH2 is recorded as the first switch gap G1, and the switch gap Gap2 between the second switch control line CKH2 and the switch enable segment EN2 on the third switch control line CKH3 is recorded as the second switch gap G2. The first switch gap G1 is not equal to the second switch gap G2. In the scan enable segment EN1 on the second scan line Gate2, the switch gap Gap2 between the first switch control line CKH1 and the switch enable segment EN2 on the second switch control line CKH2 is recorded as the third switch gap G3, and the switch gap Gap2 between the switch enable segment EN2 on the second switch control line CKH2 and the third switch control line CKH3 is recorded as the fourth switch gap G4. The third switch gap G3 is not equal to the fourth switch gap G4. In the scan enable segment EN1 on the third scan line Gate3, the switch gap Gap2 between the first switch control line CKH1 and the switch enable segment EN2 on the second switch control line CKH2 is recorded as the fifth switch gap G5, and the switch gap Gap2 between the second switch control line CKH2 and the switch enable segment EN2 on the third switch control line CKH3 is recorded as the sixth switch gap G6. The fifth switch gap G5 is not equal to the sixth switch gap G6. The fifth switch gap G5 can be equal to the first switch gap G1 and the third switch gap G3, or any two of the first switch gap G1, the third switch gap G3 and the fifth switch gap G5 are not equal. The sixth switch gap G6 can be equal to the second switch gap G2 and the fourth switch gap G4, or any two of the second switch gap G2, the fourth switch gap G4 and the sixth switch gap G6 are not equal.

[0050] For example, reference Fig.11 , the first repeating unit T1 includes a scan enable segment EN1 having a first scan enable width W1, a scan enable segment EN1 having a second scan enable width W2, and a scan enable segment EN1 having a third scan enable width W3.

Fig.12 ,and Fig.10 The difference is that the adjacent N scan lines 21 constitute a scan line group Z, and the multiple scan lines 21 include multiple scan line groups Z. In the same scan frame of the display stage, in the same scan line group Z, the scan enable segments EN1 on any two scan lines 21 have the same width. In the same scan frame of the display stage, there are at least two scan line groups Z, and the scan enable segments EN1 on the two scan lines 21 respectively located in the two scan line groups Z have different widths.

[0052] Fig.13 Another driving timing diagram of a display device provided by an embodiment of the present invention is shown in FIG. Fig.13 , in the same scan enable segment EN1, the switch enable segments EN2 on at least two switch control lines CHK have different widths, and all switch enable segments EN2 on the same switch control line CHK1 have the same width. In the embodiment of the present invention, all switch enable segments EN2 on the same switch control line CHK1 have the same width, thereby reducing the design requirements of the second drive circuit 70. The switch enable segments EN2 with different widths in the same scan enable segment EN1 destroy the inherent frequency characteristics of the switch control signal.

[0053] For example, reference Fig.13 , the scan enable segment EN1 on the first scan line Gate1 has a first scan enable width W1, within the scan enable segment EN1 on the first scan line Gate1, the switch enable segment EN2 on the first switch control line CKH1 has a first switch enable width a, the switch enable segment EN2 on the second switch control line CKH2 has a second switch enable width b, and the switch enable segment EN2 on the third switch control line CKH3 has a third switch enable width c. The scan enable segment EN1 on the second scan line Gate2 has a second scan enable width W2, within the scan enable segment EN1 on the second scan line Gate2, the switch enable segment EN2 on the first switch control line CKH1 has a first switch enable width a, the switch enable segment EN2 on the second switch control line CKH2 has a second switch enable width b, and the switch enable segment EN2 on the third switch control line CKH3 has a third switch enable width c. Any two of the first switch enable width a, the second switch enable width b, and the third switch enable width c are not equal.

[0054] For example, reference Fig.13In any scan enable segment EN1, the switch gap Gap2 between the first switch control line CKH1 and the switch enable segment EN2 on the second switch control line CKH2 is recorded as the first switch gap G1, and the switch gap Gap2 between the second switch control line CKH2 and the switch enable segment EN2 on the third switch control line CKH3 is recorded as the second switch gap G2. The first switch gap G1 is not equal to the second switch gap G2.

[0055] For example, reference Figure 1-Figure 13 The display device further includes a substrate 10, on which a scan line 21 and a first drive circuit 30 are located. A data line 22, a pixel drive transistor 23, a touch electrode layer 60, a second drive circuit 70 and a switch control line CKH are located on the substrate 10. A drive chip 40 is bound to the substrate 10. In other embodiments, the drive chip 40 may also be bound to a flexible circuit board, which is bound to the substrate 10.

[0056] Based on the same inventive concept, an embodiment of the present invention further provides a method for driving a display device, including: in the same scanning frame of the display stage, there is a scanning gap Gap1 between the scanning enable segments EN1 on two adjacent scanning lines 21, the scanning enable segments EN1 on at least two scanning lines 21 have different widths, and all scanning gaps Gap1 have the same width. The driving method provided by the embodiment of the present invention is based on the display device in the above embodiment and has the beneficial effects of the display device in the above embodiment, that is, by setting the duration of at least two scanning enable segments in the same scanning frame to be unequal, the inherent frequency characteristics of the scanning signal are destroyed, thereby weakening the electromagnetic interference energy caused by the inherent frequency, and avoiding the electromagnetic interference energy from interfering with other electronic products.
