Description

Technical Field

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

[0002] With the continuous development of the display industry, various types of display panels have gradually appeared on the market. Currently, common 3D displays use prisms to adjust the light emission direction of pixels, so that each pixel emits light in a specific direction. In this way, different brightness values are assigned to pixels with different light emission directions, allowing the human eye to see different content in different directions, thus creating binocular parallax and motion parallax, achieving a 3D display effect.

[0003] However, when the human eye is in a fixed position, only the display content of a part of the pixels can be seen, while the display content of all pixels is being refreshed, resulting in a long refresh time and slow refresh speed, affecting the viewing experience and causing power waste. Summary of the Invention

[0004] The present invention provides a display panel and a driving method thereof, and a display device, so as to improve the refresh rate and save power consumption.

[0005] According to one aspect of the present invention, there is provided a display panel, comprising:

[0006] Display function layer;

[0007] a prism layer, located on one side of the display surface of the display function layer, the prism layer including m prisms;

[0008] The display function layer includes n pixel groups, each pixel group includes m pixel groups, each pixel group includes a plurality of pixels arranged along the axial direction of the prism; a prism is simultaneously provided corresponding to the n pixel groups, the n pixel groups are arranged along the radial direction of the prism, and the n pixel groups belong to different pixel groups; a first vertical distance is defined between a geometric center of a pixel group and a first edge of the prism corresponding to the pixel group, and the first vertical distance is the same for each pixel group in the same pixel group; and an extension direction of the first edge is parallel to the axial direction;

[0009] The display function layer further includes n scan drive circuit groups, each scan drive circuit group being arranged in a one-to-one correspondence with a pixel group; a scan drive circuit group includes at least one scan drive circuit;

[0010] The display panel includes a first working state and a second working state; in the first working state, k scanning drive circuit groups are started; 2≤k<n, and the light emission directions of the k pixel groups corresponding to the k scanning drive circuit groups are all within the same viewing angle range; in the second working state, n scanning drive circuit groups are all started.

[0011] According to another aspect of the present invention, a method for driving a display panel is provided, for driving the display panel provided by any embodiment of the present invention to perform 3D display. The driving method includes:

[0012] receiving human eye position information, and determining a target working state of the display panel according to the human eye position information;

[0013] When the target operating state is determined to be the first operating state, k scan drive circuit groups are controlled to start; wherein 2≤k<n, and the light emission directions of the k pixel groups corresponding to the k scan drive circuit groups are all within the same viewing angle range;

[0014] When the target working state is determined to be the second working state, controlling the n scan driving circuit groups to start;

[0015] Among them, the human eye position information includes human eye still information and human eye movement information. When the human eye still information is received, the target working state is determined to be the first working state. When the human eye movement information is received, the target working state is determined to be the second working state.

[0016] A display device, characterized in that it includes a human eye tracking module and a display panel provided by any embodiment of the present invention, and the human eye tracking module is used to send human eye position information to a controller of the display panel.

[0017] The technical solution of the embodiment of the present invention is to divide the pixels in the display function layer into n pixel groups, the pixels belonging to the same pixel group have the same light emitting direction, and the pixels belonging to different pixel groups have different light emitting directions, and accordingly set n scanning drive circuit groups, so that the scanning drive circuit groups and the pixel groups are set in a one-to-one correspondence. When the position of the human eye is fixed, the display panel is in a first working state, and by starting k (2≤k<n) scanning drive circuit groups, the k pixel groups whose light emitting directions are within the same viewing angle range are controlled to perform display refresh. When the position of the human eye moves, the display panel is in a second working state, and by starting n scanning drive circuit groups, all pixels are controlled to perform display refresh. In this way, it can meet the viewing needs of people in different states, and when the position of the human eye is fixed, only a part of the pixels whose emitted light can be received by the human eye can be refreshed, thereby improving the refresh speed and reducing unnecessary power consumption.

[0036] Figure 1 is a structural diagram of a display panel provided by an embodiment of the present invention, Figure 2 It is along Figure 1 The cross-sectional structure diagram of the display panel taken at CC' is as follows: Figure 1 and Figure 2 As shown, the display panel 100 provided by the embodiment of the present invention includes a display function layer 10 and a prism layer 20. The prism layer 20 is located on one side of the display surface of the display function layer 10. The prism layer 20 includes m prisms L (the number after "L" in all the drawings only represents the number of the prism, the same below; Figure 1Take m=3 as an example for illustration); the display function layer 10 includes n pixel groups Q (the number after "Q" in all the drawings only represents the number of the pixel group, the same below; Figure 1 Taking n=5 as an example, a pixel group 11 includes m pixel groups Z (the number after "Z" in all the drawings only represents the number of the pixel group in the pixel group Q to which it belongs), and a pixel group Z includes a plurality of pixels P arranged along the axial direction X of the prism L; a prism L is simultaneously provided with n pixel groups Z corresponding to each other, and the n pixel groups Z are arranged along the radial direction Y of the prism L, and the n pixel groups Z belong to different pixel groups Q; a first vertical distance is defined between the geometric center of the pixel group Z and the first edge of the prism L to which the pixel group Z corresponds, and in the same pixel group Q, the first vertical distance corresponding to each pixel group Z is the same; the first edge The extension direction is parallel to the axial direction X; the display function layer also includes n scanning drive circuit groups V (the number after "V" in all the drawings only represents the number of the scanning drive circuit group, the same below), and the scanning drive circuit groups V are arranged in a one-to-one correspondence with the pixel groups Q; a scanning drive circuit group V includes at least one scanning drive circuit 11; the display panel includes a first working state and a second working state; in the first working state, k scanning drive circuit groups V are started; 2≤k<n, and the light emission directions of the k pixel groups Q corresponding to the k scanning drive circuit groups V are all within the same viewing angle range; in the second working state, n scanning drive circuit groups V are all started.

[0037] The display function layer 10 can implement a flat display function in any manner known to those skilled in the art, including but not limited to liquid crystal display, electronic paper, and LED display. The display function layer 10 can also implement a 3D display function when combined with the lens layer 20. For example, the display function layer 10 and the lens layer 20 can be bonded and fixed using a transparent optical adhesive 30.

[0038] Specifically, refer to Figure 2 , the light emitted by pixel P will converge and refract after passing through prism L. The angle of refraction is determined by the relative position of the pixel and prism. Along the radial direction Y of the prism, the light emission direction of the pixel closest to the left edge of prism L is deflected to the far right, and the light emission direction of the pixel closest to the right edge of prism L is deflected to the far left. Therefore, the light emission direction of the pixels below it can be adjusted by prism L, so that each pixel emits light in a specific direction. By assigning different brightness to pixels with different emission directions, the human eye can see different display content in different directions, producing binocular parallax and motion parallax, and realizing a 3D display effect.

[0039] When viewing a 3D display, viewers may be in a fixed position or may move around. When the human eye is fixed, only pixels whose light emission direction is within a certain viewing angle range can be seen. Pixels whose light emission direction is outside this viewing angle range cannot be seen. If all pixels are refreshed, the refresh time will be too long and slow, and unnecessary power consumption will be wasted.

[0040] To solve this problem, an embodiment of the present invention groups pixels according to the light emitting direction and adjusts the connection method between the scanning drive circuit and the pixels, so that when the position of the human eye is fixed, only the pixels with the light emitting direction in the direction of the human eye are refreshed, so as to meet the display requirements while increasing the refresh frequency and reducing power consumption. When the position of the human eye moves, the display content of all pixels is still refreshed.

[0041] Specifically, this embodiment groups pixels in the following manner. Figure 1 The display function layer includes a plurality of pixels P. A plurality of pixels arranged along the axial direction X of the prism L constitute a pixel group Z. A plurality of pixel groups Z are arranged along the radial direction Y of the prism L. One prism L is simultaneously provided with n pixel groups Z, that is, one prism L is simultaneously projected and overlapped with n pixel groups Z in a direction perpendicular to the display surface. As described above, the light emitting direction of a pixel is determined by its relative position to the prism. The relative position can be specifically characterized by the vertical distance between the left / right edge of the pixel and the prism in the radial direction Y of the prism. Figure 1 and Figure 2 , the pixels P in the same pixel group Z are at the same distance from the left edge of the prism corresponding to the pixel group Z. Therefore, the light emitting directions of each pixel P in the same pixel group Z are the same; the distances between the n pixel groups Z under a prism L and the left edge of the prism L are different. Therefore, the light emitting directions of each pixel group Z under each prism L are different; for all pixel groups Z under each prism L, in the radial direction Y of the prism, the pixel groups at the same distance from the left edge of the prism have the same light emitting direction. Accordingly, this embodiment divides the pixel groups Z with the same light emitting direction located under different prisms L into one pixel group Q. Since the display panel includes m prisms, one pixel group includes m pixel groups, and the m pixel groups Z are respectively located under different prisms and have the same relative positions with the corresponding prisms. In addition, since the n pixel groups Z under a prism L have different light emitting directions, the n pixel groups Z under a prism L belong to different pixel groups Q, and all pixel groups Z in the display function layer are divided into n pixel groups Q.

[0042] For example, Figure 1Take m=3, n=5, that is, the display panel includes three prisms L, and the display function layer includes five pixel groups Q as an example. Figure 1 As shown, the three prisms are marked as L1, L2 and L3, the five pixel groups Q are marked as Q1, Q2, Q3, Q4 and Q5, and each pixel group Q includes three pixel groups Z, marked as Z1, Z2 and Z3; Figure 1 The mark “Z1(Q1)” in the figure represents the first pixel group Z1 in the first pixel group Q1, and the rest of the similar marks can be deduced by analogy. Taking the first pixel group Q1 as an example, the three pixel groups in the pixel group are Figure 1 As shown in Z1(Q1), Z2(Q1), and Z3(Q1), pixel group Z1(Q1) is located below the first prism L1, pixel group Z2(Q1) is located below the second prism L2, and pixel group Z3(Q1) is located below the third prism L3. The first vertical distances between these three pixel groups and the first edge E1 of their corresponding prisms are equal. Therefore, the light emission directions of the three pixel groups Z in the first pixel group Q1 are the same. For the n pixel groups below a prism, the first vertical distances between each pixel group and the first edge E1 of the first prism are different. Therefore, the light emission directions of these n pixel groups are different and they belong to different pixel groups. Taking the five sub-pixel groups below the first prism L1 as an example, pixel group Z1(Q1) belongs to the first pixel group Q1, pixel group Z1(Q2) belongs to the second pixel group Q2, pixel group Z1(Q3) belongs to the third pixel group Q3, pixel group Z1(Q4) belongs to the fourth pixel group Q4, and pixel group Z1(Q5) belongs to the fifth pixel group Q5.

[0043] As mentioned above, the extending direction of the first edge E1 is parallel to the axial direction X. Therefore, the first edge refers to the edge of the prism L in the radial direction Y. The prism L has two opposite edges in the radial direction Y, such as Figure 1 The left and right edges of the prism are shown. Figure 1 The first edge E1 is taken as the left edge of the prism for illustration. In other embodiments, the first edge E1 may also be the right edge of the prism, which is not limited in the embodiment of the present invention.

[0044] Furthermore, the above-mentioned first vertical distance can be understood as the distance between the geometric center of the pixel group and the first edge of the prism corresponding to the pixel group in the radial direction Y of the prism. The radial direction Y is orthogonal to the axial direction X (the extension direction of the first edge), so it is a vertical distance.

[0045] According to the above explanation, the result of grouping pixels in this embodiment is that the light emitting directions of pixels in the same pixel group are the same, while the light emitting directions of pixels in different pixel groups are different. Figure 1As shown, based on the grouping situation, the embodiment of the present invention further sets the display function layer to include n scan drive circuit groups V (the number after "V" in all the drawings only represents the number of the scan drive circuit group, the same below; Figure 1 Taking n=5 as an example for illustration), the scanning drive circuit groups and the pixel groups are set in a one-to-one correspondence. In this way, one scanning drive circuit group can be used to scan a pixel group, control the pixels in the pixel group to refresh the display content, and realize the refresh control of pixels in the same light emitting direction. Different scanning drive circuit groups can be used to control whether different pixel groups are refreshed or not, so that the display refreshes between different pixel groups do not affect each other. The pixel group that needs to refresh the display content can be selected according to actual needs, and the corresponding scanning drive circuit group can be used to scan it, thereby improving the refresh speed and reducing unnecessary power consumption.

[0046] Specifically, the display panel is designed to have two operating states, namely a first operating state and a second operating state, according to the different states of the human eye position. The first operating state refers to the operating state of the display panel when the human eye position is fixed, and the second operating state refers to the operating state of the display panel when the human eye position moves.

[0047] In this embodiment, in the first working state, k (2≤k<n) scanning driving circuit groups V are started to scan k pixel groups and then refresh the display of k pixel groups. The other (nk) pixel groups are not scanned and not refreshed.

[0048] Specifically, the k pixel groups corresponding to the k scan drive circuit groups are all within the same viewing angle range, which can be determined based on the position of the human eye. Based on the viewing angle range, the k pixel groups whose light emission directions are within the viewing angle range can be determined, and the k scan drive circuit groups corresponding to the k pixel groups can be further determined. By controlling the activation of the k scan drive circuit groups, scanning and refreshing of the corresponding k pixel groups can be achieved, which not only meets display requirements but also eliminates the need to refresh all pixels, thereby improving refresh speed and reducing unnecessary power consumption.

[0049] In this embodiment, in the second working state, n scan driving circuits are all started, and at this time all pixels are refreshed to meet the viewing needs of human eyes at different viewing angles when they move.

[0050] For example, refer to Figure 1The five scan drive circuit groups V are labeled V1, V2, V3, V4, and V5, respectively. Scan drive circuit group V1 is configured to correspond to pixel group Q1, scan drive circuit group V2 is configured to correspond to pixel group Q2, scan drive circuit group V3 is configured to correspond to pixel group Q3, scan drive circuit group V4 is configured to correspond to pixel group Q4, and scan drive circuit group V5 is configured to correspond to pixel group Q5. Taking scan drive circuit group V1 and pixel group Q1 as an example, the corresponding configuration between the two specifically means that scan drive circuit group V1 includes at least one scan drive circuit 11, pixel group Q1 includes multiple pixels P, each pixel includes at least two sub-pixels (not shown), and the display function layer also includes scan lines (not shown). The scan drive circuits 11 in scan drive circuit group V1 are electrically connected to the sub-pixels in pixel group Q1 via the scan lines to achieve transmission of scan signals, thereby achieving display refresh (refresh can be achieved by writing data voltages in the scan state).

[0051] The scan driving circuit 11 is composed of a plurality of cascaded shift register units, and can sequentially scan sub-pixels in a pixel group in a certain order. The embodiment of the present invention does not limit the specific circuit structure of the shift register unit.

[0052] For example, Figure 1 A scan driving circuit group V including a scan driving circuit 11 is taken as an example for illustration, in which case single-side driving is performed. Figure 3 is a schematic top view of another display panel provided by an embodiment of the present invention. Figure 3 In FIG, the mark “11 (V1)” represents the scanning driving circuit in the first scanning driving circuit group V1, and so on, and the same applies below. Figure 3 As shown, in other embodiments, a scan driving circuit group V can be optionally included to include two scan driving circuits 11, and the two scan driving circuits 11 are electrically connected to the sub-pixels in the same pixel group Q through the scan lines. In this case, bilateral driving can be achieved to ensure the voltage uniformity of the scan signal on the scan line.

[0053] It should be noted that in this embodiment, in the first operating state, the k scan driving circuit groups can be driven independently or activated sequentially in a cascaded manner, and this embodiment of the present invention is not limited thereto. Similarly, in the second operating state, the n scan driving circuit groups can be activated independently or activated in a cascaded manner, and this embodiment of the present invention is not limited thereto.

[0054] In summary, the embodiment of the present invention divides the pixels in the display function layer into n pixel groups, the pixels belonging to the same pixel group have the same light emitting direction, and the pixels belonging to different pixel groups have different light emitting directions, and accordingly sets n scanning drive circuit groups, so that the scanning drive circuit groups and the pixel groups are set in one-to-one correspondence. When the position of the human eye is fixed, the display panel is in a first working state, and by starting k (2≤k<n) scanning drive circuit groups, the k pixel groups whose light emitting directions are within the same viewing angle range are controlled to perform display refresh. When the position of the human eye moves, the display panel is in a second working state, and by starting n scanning drive circuit groups, all pixels are controlled to perform display refresh. In this way, it can meet the viewing needs of people in different states, and when the position of the human eye is fixed, only a part of the pixels whose emitted light can be received by the human eye can be refreshed, thereby improving the refresh speed and reducing unnecessary power consumption.

[0055] like Figure 1 As shown, the display function layer includes a second edge E2 and a third edge E3. The extension direction of the second edge E2 is the first direction D1, and the extension direction of the third edge E3 is the second direction D2. The first direction D1 and the second direction D2 intersect (eg, are orthogonal). Figure 1 In the embodiment, the axial direction X of the prism L is parallel to the first direction D1, and the radial direction Y of the prism is parallel to the second direction D2. This arrangement is not exclusive.

[0056] Figure 4 is a schematic diagram of a top view of another display panel provided by an embodiment of the present invention. Figure 4 As shown, in other embodiments, optionally, any two of the axial direction X, the first direction D1, and the second direction D2 of the prism L intersect. Since the axial direction X is orthogonal to the radial direction Y, any two of the radial direction Y, the first direction D1, and the second direction D2 intersect. This arrangement can reduce moiré patterns.

[0057] It should be noted that Figure 4 Only one prism L is shown, and the other prisms are arranged side by side with the prism shown in the figure. For the sake of convenience, they are not shown here one by one. Figure 4 As shown, under a prism L, the light-colored inclined thin strip area marked Z (Qn) represents the pixel group Z in the n-th pixel group Qn, and the light-colored inclined thin strip area marked Z (Q1~Q n-1 ) indicates the dark, oblique, thick stripe area from the first pixel group to the (n-1)th pixel group. Figure 4 Only one scanning drive circuit group Vn is illustrated, which is set corresponding to the nth pixel group Qn. As mentioned above, the display function layer also includes (n-1) scanning drive circuits, which correspond to the first pixel group to the (n-1) pixel group respectively. For the sake of convenience, they are not illustrated here one by one.

[0058] Reference Figure 4 It should be noted that the technical solution of the embodiments of the present invention does not change the arrangement of pixels in the display function layer; it merely regroups the pixels based on the tilt of the prisms. The grouping principle is the same as described above: pixels located below the same prism and at equal vertical distances from the first edge E1 of the prism along the radial direction Y are grouped together, while pixels located below different prisms and at equal vertical distances from the first edge E1 of the prism along the radial direction Y are grouped together. This ensures that pixels within the same pixel group have the same light emission direction, while pixels in different pixel groups have different light emission directions.

[0059] In this embodiment, the pixel arrangement can be any arrangement currently known in the industry and is not limited in this embodiment of the present invention. For example, taking a pixel including red (R), green (G), and blue (B) sub-pixels as an example, the pixel arrangement includes but is not limited to the standard RGB arrangement, Pentile arrangement, Delta arrangement, diamond arrangement, and pearl arrangement.

[0060] As described above, different scan drive circuit groups can be independently activated or cascaded. In contrast, cascade activation can reduce the number of signal lines (e.g., level signal lines, start signal lines, clock signal lines) between the driver chip and the scan drive circuit. The following describes in further detail the implementation of cascade activation of different scan drive circuit groups.

[0061] Figure 5 FIG. 1 is a schematic diagram of a connection circuit between scan drive circuits in a display panel provided by an embodiment of the present invention. Figure 5As shown, optionally, the display function layer also includes a plurality of gating modules 12, and the gating modules 12 are arranged in a one-to-one correspondence with the scan driving circuit 11; the gating module 12 includes a first end 121, a second end 122, a third end 123 and a fourth end 124; the first end 121 of the gating module 12 is electrically connected to the first end 111 of the corresponding scan driving circuit; the second end 122 of the gating module 12 is electrically connected to the second end 112 of the corresponding scan driving circuit 11; the fourth end 124 of the i-th gating module 12 is electrically connected to the third end 123 of the (i+1)-th gating module 12, 1≤i≤n-1; one of the first end 111 of the scan driving circuit 11 and the second end 112 of the scan driving circuit 11 is the cascade signal input end of the scan driving circuit 11, and the other is the cascade signal output end of the scan driving circuit 11. The gating module 12 includes a first gating state and a second gating state; in the first gating state, the first end 121 of the gating module 12 and the third end 123 of the gating module 12 are connected, the second end 122 of the gating module 12 and the fourth end 124 of the gating module 12 are connected, and the third end 123 of the gating module 12 and the fourth end 124 of the gating module 12 are disconnected; in the second gating state, the first end 111 of the gating module 12 and the third end 123 of the gating module 12 are disconnected, the second end 122 of the gating module 12 and the fourth end 124 of the gating module 12 are disconnected, and the third end 123 of the gating module 12 and the fourth end 124 of the gating module 12 are connected; the gating states of at least some of the gating modules 12 are independently controlled.

[0062] Among them, the display function layer includes multiple gating modules, and the gating states of at least some of the gating modules 12 are independently controlled. Specifically, when the scan driving circuit is set in a unilateral driving manner, a scan driving circuit group V includes a scan driving circuit 11. At this time, the number of gating modules 12 is n, and the gating states of each gating module 12 are independently controlled and unrelated to each other; when the scan driving circuit is set in a bilateral driving manner, a scan driving circuit group V1 includes two scan driving circuits 11. At this time, the number of gating modules 12 is 2n, and the gating states of the two gating modules corresponding to the two scan driving circuits belonging to the same scan driving circuit group can be controlled simultaneously, and the gating states of the gating modules corresponding to the scan driving circuits belonging to different scan driving circuit groups are independently controlled.

[0063] Specifically, the gating state of the gating module corresponds to the start / stop state of the scan driver circuit group. When the gating module is controlled to be in the first gating state, the corresponding scan driver circuit group is in the enabled state; when the gating module is controlled to be in the second gating state, the corresponding scan driver circuit group is in the disabled state, i.e., it stops outputting scan signals. In this way, the actual start / stop requirements of each scan driver circuit group can be determined based on the user's state, and the gating state of the corresponding gating module can be determined. By controlling the gating state of each gating module, multiple scan driver circuit groups that need to be enabled can be activated in a cascaded manner.

[0064] For example, Figure 6 yes Figure 5 The circuit is a schematic structural diagram when the display panel is in the first working state, as shown in FIG. Figure 6 As shown, assuming that according to the position of the human eye, it is determined that the second pixel group and the n-th pixel group need to be refreshed, the two gating modules 12 corresponding to the second scan driving circuit group V2 and the n-th scan driving circuit group Vn can be controlled to be in the first gating state, and the remaining gating modules 12 are in the second gating state. In this way, the second scan driving circuit group V2 and the n-th scan driving circuit group Vn can be in the started state, and the other scan driving circuit groups are in the stopped state. The cascade signal transmission process is specifically as follows: the initial cascade signal STV bypasses the first scan driving circuit group V1, is transmitted to the fourth terminal 124 through the third terminal 123 of the first selection module 12, and then is transmitted to the scan driving circuit in the second scan driving circuit group V2 through the third terminal 123 and the first terminal 121 of the second selection module, and then is transmitted to the third terminal 123 of the third selection module 12 through the second terminal 122 and the fourth terminal 124 of the second selection module 12, and bypasses the third scan driving circuit group V3 to the (n-1)th scan driving circuit group, and is transmitted to the third terminal 123 of the nth selection module 12, and then passes through the second terminal 112 of the nth scan driving circuit group Vn to complete the cascade start-up of the second scan driving circuit group and the nth scan driving circuit group.

[0065] When the display panel is in the second working state, all the gating modules 12 are in the first gating state, and the cascade signal passes through the first scan driving circuit group V1 to the nth scan driving circuit group in sequence, thereby realizing cascade startup of all scan driving circuit groups.

[0066] Most current scan driving circuits have a bidirectional scanning function. Therefore, one of the first terminal 111 of the scan driving circuit 11 and the second terminal 112 of the scan driving circuit 11 is the cascade signal input terminal of the scan driving circuit 11, and the other is the cascade signal output terminal of the scan driving circuit 11, which can be as follows: Figure 5The first end 111 of the scan driving circuit 11 shown is the cascade signal input end of the scan driving circuit 11, and the second end 112 of the scan driving circuit 11 is the cascade signal output end of the scan driving circuit 11. Alternatively, the second end 112 of the scan driving circuit 11 can be the cascade signal input end of the scan driving circuit 11, and the first end 111 of the scan driving circuit 11 can be the cascade signal output end of the scan driving circuit 11. This embodiment of the present invention is not limited to this.

[0067] Figure 7 yes Figure 5 A structural diagram of the gating module in the circuit shown is as follows: Figure 7 As shown, optionally, the gating module 12 includes a first switch unit 1201, a second switch unit 1202 and a third switch unit 1203; the first end of the first switch unit 1201 is the first end 121 of the gating module; the first end of the second switch unit 1202 is the second end 122 of the gating module; the second end of the first switch unit 1201 and the first end of the third switch unit 1203 are electrically connected to a first node N1, and the first node N1 is the third end 123 of the gating module; the second end of the second switch unit 1202 and the second end of the third switch unit 1203 are electrically connected to a second node N2, and the second node N2 is the fourth end 124 of the gating module; the first switch unit 12 01. The control ends of the second switch unit 1202 and the third switch unit 1203 are both electrically connected to the selection control signal line 13; the selection control signal line 13 is used to receive the selection control signal, and the selection control signal includes a first control signal and a second control signal with different voltages; when the selection control signal line 13 receives the first control signal, the first switch unit 1201 and the second switch unit 1202 are turned on, the third switch unit 1203 is turned off, and the selection module is in the first selection state; when the selection control signal line 13 receives the second control signal, the first switch unit 1201 and the second switch unit 1202 are turned off, the third switch unit 1203 is turned on, and the selection module is in the second selection state.

[0068] Among them, the on and off of the first switch unit 1201 and the second switch unit 1202 are controlled by the same signal, and the on and off of the third switch unit 1203 are controlled by different signals from the first switch unit 1201 / the second switch unit 1202. In this way, different control signals can be transmitted through the selection control signal line to realize the conduction (offset) of the first switch unit and the second switch unit, and the shutdown (conduction) of the third switch unit 1203, so that the state of the selection module is switched between the first selection state and the second selection state. Then, according to actual needs, the selection state of each selection module can be flexibly controlled to realize the start and stop control of the corresponding scan driving circuit group, and realize the cascade start of at least part of the scan driving circuit group.

[0069] As a feasible implementation method, Figure 7 As shown, optionally, the first switch unit 1201 and the second switch unit 1202 both include N-type transistors, the third switch unit 1202 includes a P-type transistor, and the voltage of the first control signal is greater than the voltage of the second control signal.

[0070] Specifically, when the selection control signal is at a high level, the first switch unit 1201 and the second switch unit 1202 are turned on, the third switch unit 1202 is turned off, the selection module is in a first selection state, and the corresponding scan drive circuit group is in a start-up state; when the selection control signal is at a low level, the first switch unit 1201 and the second switch unit 1202 are turned off, the third switch unit 1202 is turned on, the selection module is in a second selection state, and the corresponding scan drive circuit group is in a shutdown state.

[0071] As another possible implementation, Figure 8 yes Figure 5 Another structural diagram of the gating module in the circuit shown is as follows: Figure 8 As shown, the first switch unit 1201 and the second switch unit 1202 both include P-type transistors, the third switch unit 1203 includes an N-type transistor, and the voltage of the first control signal is less than the voltage of the second control signal.

[0072] Specifically, when the selection control signal is at a low level, the first switch unit 1201 and the second switch unit 1202 are turned on, the third switch unit 1202 is turned off, the selection module is in a first selection state, and the corresponding scan drive circuit group is in a start-up state; when the selection control signal is at a high level, the first switch unit 1201 and the second switch unit 1202 are turned off, the third switch unit 1202 is turned on, the selection module is in a second selection state, and the corresponding scan drive circuit group is in a shutdown state.

[0073] It should be noted that the embodiment of the present invention does not limit the number of transistors in the first switch unit 1201, the second switch unit 1202, and the third switch unit 1203, and they only need to include at least one transistor. Figure 7 and Figure 8 The number of transistors in each switching unit shown is for illustration only and is not limiting.

[0074] Figure 9 yes Figure 4 A schematic diagram of the enlarged structure of the T1 region, combined with Figure 4 、 Figure 5 and Figure 9As shown, at least part of the scan driving circuits 11 are arranged side by side along the first direction D1; the scan driving circuit 11 includes a plurality of cascaded shift register units 1101, and the plurality of shift register units 1101 are arranged along the second direction D2; the first direction D1 is parallel to the extension direction of the second edge E2 of the display function layer, and the second direction D2 is parallel to the extension direction of the third edge E3 of the display function layer; when the selection modules 12 are both in the first selection state, the transmission directions of the cascade signals of the two adjacent scan driving circuits 11 along the first direction D1 are the same.

[0075] Among them, at least part of the scan driving circuits 11 are arranged side by side along the first direction D1. All the scan driving circuits can be arranged side by side along the first direction D1, or part of the scan driving circuits can be arranged side by side along the first direction D1, and the other part of the scan driving circuits can be arranged side by side along the second direction D2.

[0076] For example, Figure 10 is a schematic diagram of a top view of another display panel provided by an embodiment of the present invention. Figure 10 As shown, optionally, the display function layer 10 includes a display area AA and a non-display area NA surrounding the display area AA, the non-display area NA includes a first area W1, a second area W2, a third area W3 and a fourth area W4, the first area W1 and the second area W2 are relatively arranged along the first direction D1, and the third area W3 and the fourth area W4 are relatively arranged along the second direction D2; the scanning driving circuit 11 is arranged in at least two of the first area W1, the second area W2, the third area W3 and the fourth area W4.

[0077] The first region W1, the second region W2, the third region W3, and the fourth region W4 respectively refer to the upper, lower, left, and right borders of the display function layer 10. The scan driver circuit 11 can be disposed within at least two of these borders. Distributing the scan driver circuits helps to balance the border widths and enhance the appearance.

[0078] For example, Figure 1 and Figure 3 For example, all scan driving circuits are arranged side by side along the first direction D1. Figure 10 It is illustrated by taking an example that all the scan driving circuits are dispersedly arranged in the first area W1 , the second area W2 , the third area W3 and the fourth area W4 .

[0079] Reference Figure 1 , it should be noted that, Figure 1Taking the scan driver circuits located in the upper frame as an example, when the scan driver circuits are configured using a unilateral drive method and arranged along the first direction D1, all scan driver circuits can also be dispersed across the first region W1 and the second region W2. In short, regardless of whether the scan driver circuits are configured using a unilateral drive method or a bilateral drive method, all scan driver circuits can be distributed across at least two of the first region W1, the second region W2, the third region W3, and the fourth region W4, and this is not limited in this embodiment of the present invention.

[0080] The transmission direction of the scan driving circuit specifically refers to the direction of the physical position angle, such as Figure 4 and Figure 9 As shown, in physical position, the scan driving circuit includes a head end U1 and an end U2 opposite to each other along the second direction D2. The transmission direction of the cascade signal of the scan driving circuit can be from the head end U1 to the end U2, or from the end U2 to the head end U1.

[0081] Specifically, for any scan driving circuit, the head end U1 can be used as the first end 111 of the scan driving circuit, and the end end U2 can be used as the second end 112 of the scan driving circuit. In this way, when the first end 111 is the cascade signal input end and the second end 112 is the cascade signal output end, the transmission direction of the cascade signal of the two adjacent scan driving circuits 11 along the first direction D1 is the direction from the head end U1 to the end end U2, and the pixel group is scanned from left to right; when the first end 111 is the cascade signal output end and the second end is the cascade signal input end, the transmission direction of the cascade signal of the two adjacent scan driving circuits 11 along the first direction D1 is the direction from the end U2 to the head end U1, and the pixel group is scanned from right to left.

[0082] For example, Figure 5 The first end 111 (head end U1) is used as the cascade signal input end, and the second end 112 (end end U2) is used as the cascade signal output end. Figure 1 or Figure 3 When all scan driver circuits 11 are arranged side by side along the first direction D1, if the gating modules 12 are all in the first gating state, the transmission direction of the cascade signal of two adjacent scan driver circuits 11 along the first direction D1 is from the starting end U1 to the ending end U2, and the pixel group can be scanned from left to right. This arrangement allows all gating modules to be placed next to the starting end U1 of the scan driver circuit, or all gating modules to be placed next to the ending end U2 of the scan driver circuit, reducing layout difficulty.

[0083] As described above, a portion of the scan driving circuits may be arranged side by side along the first direction D1, while another portion of the scan driving circuits may be arranged side by side along the second direction D2. The above-described method may also be employed for the scan driving circuits arranged side by side along the second direction D2, such that the transmission directions of the cascade signals of adjacent scan driving circuits along the second direction D2 are the same. This is not particularly limited in the embodiments of the present invention.

[0084] In summary, no matter how the scan driving circuit is laid out, this embodiment designs the transmission direction of the cascade signal of two adjacent scan driving circuits to be the same when they are started, so that the corresponding selection modules can be located on the same side of the scan driving circuits arranged side by side in the same direction, thereby reducing the layout difficulty of the selection modules.

[0085] Figure 11 A schematic diagram of a connection circuit between scan drive circuits in a display panel provided by an embodiment of the present invention, combined with Figure 4 、 Figure 9 and Figure 11 As shown, in other embodiments, optionally, when the gating modules are all in the first gating state, the transmission directions of the cascade signals of two adjacent scan driving circuits along the first direction D1 are opposite.

[0086] Specifically, for any two scan driving circuits adjacent to each other along the first direction D1, the head end U1 of one of the scan driving circuits can be used as the first end 111 of the scan driving circuit, and the end U2 can be used as the second end 112 of the scan driving circuit; the end U2 of the other scan driving circuit can be used as the first end 111 of the scan driving circuit, and the head end U1 can be used as the second end 112 of the scan driving circuit. In this way, when the first end 111 is the cascade signal input end and the second end 112 is the cascade signal output end, or when the first end 111 is the cascade signal output end and the second end is the cascade signal input end, the transmission directions of the cascade signals of the two scan driving circuits 11 adjacent to each other along the first direction D1 are opposite.

[0087] For example, refer to Figure 11, the head end U1 of the scan driving circuit 11 of the first scan driving circuit group V1 serves as the first end 111 of the scan driving circuit, and the end U2 serves as the second end 112 of the scan driving circuit; the end U2 of the scan driving circuit 11 of the second scan driving circuit group V2 serves as the first end 111 of the scan driving circuit, and the head end U1 serves as the second end 112 of the scan driving circuit; the head end U1 of the scan driving circuit 11 of the third scan driving circuit group V3 serves as the first end 111 of the scan driving circuit, and the end U2 serves as the second end 112 of the scan driving circuit; the end U2 of the scan driving circuit 11 of the fourth scan driving circuit group V4 serves as the first end 111 of the scan driving circuit, and the head end U1 serves as the second end 112 of the scan driving circuit, and so on. Assuming that all scan driving circuits 11 are arranged side by side along the first direction D1, then in the second working state, when all the selection modules are in the first selection state, the transmission direction of the cascade signal of the first scan driving circuit group V1 is from the head end U1 to the end end U2, scanning the corresponding pixel group from left to right; the transmission direction of the cascade signal of the second scan driving circuit group V2 is from the end end U2 to the head end U1, scanning the corresponding pixel group from right to left, and so on, so that the transmission directions of the cascade signals of the two adjacent scan driving circuits are opposite, and the transmission route of the cascade signal is similar to a snake.

[0088] Similarly, it should be noted that when a portion of the scan driving circuits are arranged side by side along the first direction D1 and another portion of the scan driving circuits are arranged side by side along the second direction D2, the above-mentioned method can also be adopted for the scan driving circuits arranged side by side along the second direction D2, so that the transmission directions of the cascade signals of the adjacent scan driving circuits along the second direction D2 are opposite. The embodiments of the present invention do not impose any special limitations on this.

[0089] In the embodiment of the present invention, when all the gating modules are in the first gating state, by setting the transmission directions of the cascade signals of two adjacent scan driving circuits along the first direction D1 to be the same and opposite, it is beneficial to shorten the transmission path between the cascade signals of the two adjacent scan driving circuits and reduce IR drop.

[0090] As described above, the shift register unit in the scan driving circuit is electrically connected to the sub-pixels in the pixel group through the scan lines. Figure 9 Optionally, the extension direction of the scanning line 14 is parallel to the axial direction X, and one scanning line 12 is electrically connected to multiple sub-pixels arranged along the axial direction X at the same time.

[0091] Specifically, since multiple pixels P belonging to the same pixel group Z are arranged along the axial direction X of the prism L, and the scanning line 14 is used to transmit scanning signals to the sub-pixels in the pixel group Z, by setting the extension direction of the scanning line 14 to be aligned with the axial direction X, the scanning line 14 is conveniently electrically connected to the multiple sub-pixels arranged along the axial direction X at the same time, thereby realizing the transmission of the scanning signal.

[0092] For example, refer to Figure 9 When the axial direction X of the prism L intersects both the first direction D1 and the second direction D2, the extending direction of the scanning line 14 also intersects both the first direction D1 and the second direction D2. Figure 1 , when the axial direction X of the prism L is parallel to the first direction D1, the extending direction of the scanning line (not shown) is parallel to the first direction D1.

[0093] For example, Figure 9 As an example, a pixel comprising three sub-pixels (R / G / B) arranged in a standard RGB configuration is used. In the scan driver circuit, the output of a shift register unit 1101 is electrically connected to multiple sub-pixels arranged along an axis via a scan line 14. The driver chip controls the shift register unit 1101 to input a scan enable signal to these sub-pixels and writes data signals to these sub-pixels via data lines (not shown), thereby enabling refresh of these sub-pixels. Other pixel arrangements are also applicable and are not illustrated here.

[0094] Reference Figure 9 , the output end of the shift register unit 1101 is electrically connected to the scan line 14 via the connection line 1102. In this regard, it should be noted that when a portion of the scan driving circuits are arranged side by side along the first direction D1 and another portion of the scan driving circuits are arranged side by side along the second direction D2, the connection line between the output end of the shift register unit and the scan line 14 in the scan driving circuits arranged side by side along the second direction D2 can extend from the non-display area to the display area along the second direction D2, and be electrically connected to the scan line by punching, so as to realize the transmission of the scan signal.

[0095] Based on the same inventive concept, an embodiment of the present invention further provides a method for driving a display panel, which is used to drive the display panel provided by any embodiment of the present invention to perform 3D display. The driving method can be executed by a controller in a display device. Figure 12 FIG. 1 is a flow chart of a method for driving a display panel provided by an embodiment of the present invention. Figure 12 As shown, the driving method includes the following steps:

[0096] S101 : Receive human eye position information, and determine a target working state of a display panel according to the human eye position information.

[0097] S102 , when it is determined that the target working state is the first working state, controlling k scan driving circuit groups to start; wherein 2≤k<n, and the light emission directions of the k pixel groups corresponding to the k scan driving circuit groups are all within the same viewing angle range.

[0098] S103 : When it is determined that the target working state is the second working state, control all n scan driving circuit groups to start.

[0099] The eye position information may be acquired by an eye tracking module built into the display device and sent to the controller, so that the controller determines the target working state of the display panel according to the eye position information.

[0100] Among them, the human eye position information includes human eye still information and human eye movement information. When the human eye still information is received, the target working state is determined to be the first working state. When the human eye movement information is received, the target working state is determined to be the second working state.

[0101] Specifically, when the human eye is still, the viewing angle range of the human eye can be determined based on the position of the human eye, and then the k pixel groups whose light emitting directions are within the viewing angle range can be determined, and then the k scanning drive circuit groups corresponding to the k pixel groups can be determined. By controlling the start-up of the k scanning drive circuit groups, the scanning and refresh of the corresponding k pixel groups can be achieved, which can meet the display requirements without refreshing all pixels, thereby improving the refresh speed and reducing unnecessary power consumption.

[0102] Specifically, when the human eye moves, it is necessary to control n scanning driving circuits to start up, so as to refresh the display of all pixels and meet the viewing requirements at different viewing angles when the human eye moves.

[0103] The driving method provided by an embodiment of the present invention determines the target working state of the display panel based on the position information of the human eye. When the human eye is stationary, the target working state is determined to be the first working state, and k (k<n) scanning driving circuit groups are controlled to start up to refresh the display of k pixel groups whose light emitting directions are within the same viewing angle range. When the human eye moves, the target working state is determined to be the second working state, and n scanning driving circuit groups are controlled to start up to refresh the display of all pixel groups. In this way, it can not only meet the viewing needs of people in different states, but also, when the position of the human eye is fixed, only a part of the pixels whose emitted light can be received by the human eye can be refreshed, thereby improving the refresh speed and reducing unnecessary power consumption.

[0104] As described above, the optional display function layer further includes a plurality of gating modules, each of which corresponds to a scan driving circuit. In this case, optionally, controlling k scan driving circuit groups to be activated includes controlling the gating modules corresponding to the k scan driving circuit groups to be in a first gating state, and controlling the gating modules corresponding to the remaining scan driving circuit groups to be in a second gating state. Alternatively, controlling all n scan driving circuit groups to be activated includes controlling all gating modules to be in the first gating state.

[0105] With such a setting, at least part of the scanning driving circuit group can be cascaded and started according to actual needs, which is beneficial to reducing the number of signal lines (such as level signal lines, start signal lines, clock signal lines) and other signal lines between the driving chip and the scanning driving circuit. The structure and specific working principle of the selection module can be referred to the above explanation and will not be repeated here.

[0106] Based on the same inventive concept, an embodiment of the present invention further provides a display device. Figure 13 is a structural diagram of a display device provided by an embodiment of the present invention, such as Figure 13 As shown, the display device 200 includes an eye tracking module and a display panel provided by any embodiment of the present invention. The eye tracking module is used to send eye position information to a controller of the display panel. Since the display device provided by an embodiment of the present invention includes the display panel provided by any embodiment of the present invention, it has the same beneficial effects as the above-mentioned display panel embodiments. For details, please refer to the description of the above-mentioned display panel embodiments, which will not be repeated here. The display device provided by an embodiment of the present invention can be any type of 3D display, and the embodiment of the present invention is not limited to this.

[0107] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
