Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a light-emitting panel and a display device. Background Art

[0002] Mini LED (Mini light-emitting diode) is a sub-millimeter light-emitting diode, which has the characteristics of high brightness, high contrast, high color saturation, low power consumption, fast response speed, and long life. It is widely used in the display field. The Mini LED array is arranged to form a light-emitting panel, which can be used as a backlight source for an LCD (Liquid Crystal Display), or the light-emitting panel can be directly used as a display panel for displaying images. The prior art divides the Mini LEDs arranged in an array in the light-emitting panel into partitions, and the light emission of each partition can be independently controlled. Taking the light-emitting panel as a backlight source as an example, when the LCD display resolution is high, the partition control of the light-emitting panel to emit light will make the display fineness more difficult to debug, and it is easy to have poor display effects such as halo at the corners of the image. Although increasing the number of Mini LEDs and the number of partitions can improve the fineness of the picture displayed by the display panel, it will also lead to an increase in power consumption. Summary of the invention

[0003] Embodiments of the present invention provide a light-emitting panel and a display device to solve the problem in the prior art that a high number of partitions improves display fineness while causing increased power consumption.

[0004] In a first aspect, an embodiment of the present invention provides a light-emitting panel, the light-emitting panel comprising:

[0005] A partition group, the partition group includes n*n partitions, n is an integer, n≥2, and the partition includes at least one light-emitting device; in the partition group, the n partitions are arranged into a first partition row along a first direction;

[0006] A signal line group includes n signal lines extending along a first direction; wherein one signal line connects n partitions in the partition group, and the n partitions in the partition group connected to one signal line are located in at least two first partition rows.

[0007] In a second aspect, based on the same inventive concept, an embodiment of the present invention further provides a display device, comprising the light-emitting panel provided by any embodiment of the present invention.

[0008] The light-emitting panel and display device provided by the embodiment of the present invention have the following beneficial effects: the embodiment of the present invention can set a fixed number of partitions in the light-emitting panel, and when displaying delicate images, by controlling all partitions to emit light, the image corner halo and other display defects are weakened to improve the display effect of delicate images; when displaying non-delicate images, by controlling some partitions not to emit light, the number of luminous partitions is reduced to reduce power consumption. In addition, the n signal lines in the signal line group in the embodiment of the present invention are cross-connected to the n first partition rows in the partition group, and the working modes of multiple partitions connected thereto can be uniformly controlled by one signal line. The control method is simple, and the luminous partitions in the entire luminous area can be controlled to be relatively uniformly reduced, so that the luminous partitions are relatively evenly distributed in the entire luminous area, ensuring the display effect when displaying non-delicate images.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0043] In the prior art, Mini LED is made on PCB (Printed Circuit Board) as a light-emitting panel. Multiple partitions are divided on the light-emitting panel to independently control the brightness of each partition. The number of partitions that can be divided on a conventional PCB light-emitting panel is limited by the number of channels that the driver chip can provide. Increasing the number of channels of the driver chip will increase the cost. The design of horizontal and vertical cross-select lines and data lines on the light-emitting panel makes it easy to achieve more partitions. The number of partitions is not limited by the number of channels of the driver chip. Increasing the number of Mini LEDs and the number of partitions can improve the delicacy of the picture displayed by the display panel. However, the increase in the number of Mini LEDs in the light-emitting panel will also significantly affect related performance such as power consumption.

[0044] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a light-emitting panel, which groups multiple partitions in the light-emitting panel, and specially designs the connection method between the signal line and each partition in the partition group, so that the signal line can be used to adjust the light emission of the partitions of the light-emitting panel. This can weaken the image corner halo and other display defects when displaying delicate images, and reduce power consumption when displaying non-delicate images.

[0045] Figure 1 A schematic diagram of a light-emitting panel provided by an embodiment of the present invention, Figure 2 for Figure 1 A schematic diagram of a cross section at the midline AA′. Figure 1 As shown, the light-emitting panel 100 includes a plurality of partitions 10 and a plurality of signal lines 20 extending along a first direction a, the plurality of partitions 10 are arranged in an array, and each partition 10 includes at least one light-emitting device. The number of light-emitting devices in each partition 10 may be the same or different. From the perspective of the light-emitting panel 100 as a whole, the area formed by the plurality of partitions 10 arranged in an array is the light-emitting area of ​​the light-emitting panel 100. Figure 1 The light-emitting devices in the partition 10 are not shown in the figure, wherein the light-emitting devices are Mini LEDs. When the partition 10 includes two or more light-emitting devices, the multiple light-emitting devices in the same partition 10 can be connected in parallel or in series. In some embodiments, the light-emitting panel 100 can be used as a backlight source for a liquid crystal display device. In other embodiments, the light-emitting devices in the partitions serve as display sub-pixels, and the light-emitting panel 100 can be used as a display panel for displaying an image.

[0046] It should be noted that the signal line 20 extending along the first direction a only means that the direction of the signal line 20 is the first direction a, and does not limit the line shape of the signal line 20. The signal line 20 can be a folded line running along the first direction a.

[0047] The light-emitting panel 100 includes row gate lines and data lines whose extension directions intersect each other. The row gate lines and the data lines are both located in the driving layer. One row gate line is connected to a plurality of partitions 10 in its extension direction, and one data line is connected to a plurality of partitions 10 in its extension direction. By driving the plurality of partitions 10 in the light-emitting panel 100 in cooperation with the row gate lines and the data lines, the number of the partitions 10 is not limited by the number of channels of the driving chip, and a relatively large number of partitions 10 can be set in the light-emitting panel 100. When all the partitions 10 are luminous, the display effect of the light-emitting panel 100 in displaying delicate images can be improved.

[0048] Figure 2 The cross-sectional view of the light-emitting panel is shown, and it can be seen that the light-emitting panel 100 includes a substrate 00, a driving layer 01, and a light-emitting device 11 located on a side of the driving layer 01 away from the substrate 00. The substrate 00 may be a glass substrate, the driving layer 01 includes a stacked metal layer and an insulating dielectric layer, and the signal line 20 is located in the metal layer of the driving layer 01. Optionally, the driving layer 01 further includes a partition control circuit, which is used to control the light emission of the partition 10, and the partition control circuit includes a thin film transistor.

[0049] In another embodiment, the light emitting panel includes a PCB, and the light emitting device is fixed on the PCB. The PCB is printed with row gate lines and data lines whose extending directions intersect each other, so as to realize setting a large number of partitions in the light emitting panel.

[0050] like Figure 1 As shown, the light emitting panel 100 includes a partition group 1 and a signal line group 2, and the signal line 20 in the signal line group 2 is connected to the partition 10 in the partition group 1. The partition group 1 includes n*n partitions 10, n is an integer, n≥2, and the signal line group 2 includes n signal lines 20. Figure 1 In the figure, n=2 is used for illustration only, and the dotted lines crossing horizontally and vertically divide the light emitting panel 100 into a plurality of partition groups 1. One signal line group 2 is connected to a plurality of partition groups 1, and the partition groups 1 corresponding to one signal line group 2 are repeatedly arranged in the first direction a.

[0051] In the partition group 1, n partitions 10 are arranged into a first partition row 1H along a first direction a, and n partitions 10 are arranged into a second partition row 2H along a second direction b, and the first direction a and the second direction b intersect each other. The number of signal lines 20 included in the signal line group 2 is the same as the number of first partition rows 1H in the partition group 1. Among them, one signal line 20 is connected to n partitions 10 in the partition group 1, and n partitions 10 in the partition group 1 connected to one signal line 20 are located in at least two first partition rows 1H. In other words, one signal line 20 is connected to the partitions 10 in at least two first partition rows 1H in the partition group 1.

[0052] For example, when n=2, the partition group 1 includes 4 partitions 10, which are divided into two first partition rows 1H, and the signal line group 2 includes 2 signal lines 20. One signal line 20 connects two partitions 10 in the partition group 1, and the two partitions 10 in the partition group 1 connected to one signal line 20 are respectively located in two first partition rows 1H.

[0053] For example, when n=3, the partition group 1 includes 9 partitions 10, which are divided into three first partition rows 1H, and the signal line group 2 includes 3 signal lines 20. One signal line 20 connects the three partitions 10 in the partition group 1, and the three partitions 10 in the partition group 1 connected to one signal line 20 are located in at least two first partition rows 1H.

[0054] Figure 1 Schematically shows a connection mode between a signal line 20 and a partition 10 when n=2. In another embodiment, Figure 3 Schematic diagram of another light-emitting panel provided by an embodiment of the present invention. Figure 3 As shown, the partition group 1 includes 2*2 partitions 10, that is, n=2, and the signal line group 2 includes 2 signal lines 20. One signal line 20 connects the two partitions 10 in the partition group 1, and the two partitions 10 belonging to one partition group 1 connected to one signal line 20 are respectively located in two first partition rows 1H. In the embodiment of the present invention, one partition group 1 corresponds to one signal line group 2, and one signal line group 2 can be connected to multiple partition groups 1. Among them, one partition group 1 corresponds to one signal line group 2, which means that n*n partitions 10 in one partition group 1 are connected to n signal lines 20 in one signal line group 2, which means that n first partition rows 1H in the partition group 1 are connected to n signal lines 20 in the signal line group 2. In the embodiment of the present invention, a signal line 20 is connected to the partitions 10 in at least two first partition rows 1H in the partition group 1. The n partitions 10 belonging to a partition group 1 connected by a signal line 20 are not all located in one first partition row 1H, which means that the n signal lines 20 in the signal line group 2 need to be cross-connected to the n first partition rows 1H in the partition group 1.

[0055] The light-emitting panel 100 provided in the embodiment of the present invention is provided with a partition group 1, and the partition group 1 includes n*n partitions 10. The partition group 1 is controlled by n signal lines 20 in the signal line group 2, and each signal line 20 is connected to the same number of partitions 10 belonging to the same partition group 1. The n signal lines 20 in the signal line group 2 are independent of each other, so each signal line 20 can independently control the partition 10 connected thereto. For a partition group 1, when the n signal lines 20 all control the partitions 10 connected thereto to emit light, all the partitions 10 in the partition group 1 are illuminated, and the number of the illuminated partitions 10 in the partition group 1 is the largest; when at least one of the n signal lines 20 controls the partition 10 connected thereto not to emit light, the number of the illuminated partitions 10 in the partition group 1 is reduced, and the power consumption of the light-emitting panel 100 can be reduced.

[0056] From the perspective of the light-emitting panel 100 as a whole, setting a large number of partitions 10 in the light-emitting panel 100 can improve the display effect of the light-emitting panel 100 in displaying delicate images. By dividing the large number of partitions 10 into multiple partitions 1 and correspondingly setting multiple signal line groups 2, it is possible to control all the partitions 10 to emit light or control only some of the partitions 10 to emit light. In the case where the number of partitions 1 set in the light-emitting panel 100 is fixed: when the light-emitting panel 100 is used to display delicate images, by controlling all the partitions 10 to emit light, poor display such as halo at the corners of the image can be weakened, and the display effect of delicate images can be improved; when the light-emitting panel 100 is used to display non-delicate images, controlling some partitions 10 not to emit light to reduce the number of emitting partitions 10 can reduce power consumption. In addition, in the embodiment of the present invention, n signal lines 20 in the signal line group 2 are cross-connected to n first partition rows 1H in the partition group 1. The n partitions 10 belonging to a partition group 1 connected by one signal line 20 are not all located in one first partition row 1H. One signal line 20 can be used to uniformly control the working modes of multiple partitions 10 connected thereto (for example, multiple partitions 10 can be controlled not to emit light at the same time). The control method is simple, and can control the relatively uniform reduction of the luminous partitions 10 in the entire luminous area, so that the luminous partitions 10 are relatively evenly distributed in the entire luminous area, thereby ensuring the display effect when displaying non-delicate images.

[0057] In some embodiments, one partition 10 includes one light-emitting device. When the number of light-emitting devices provided in the light-emitting panel 100 is fixed, the light-emitting panel 100 can be divided into a maximum number of partitions 10. When the number of partitions divided in the light-emitting panel 100 is fixed: when all partitions 10 are emitting light, the solution that one partition 10 includes one light-emitting device can maximize the display effect of displaying delicate images; when displaying non-delicate images, using the signal line 20 to control some partitions 10 not to emit light can reduce power consumption while ensuring the display effect.

[0058] In other embodiments, a partition 10 includes two or more light-emitting devices, and two or more light-emitting devices in a partition 10 can be controlled simultaneously. In the case where the number of partitions divided in the light-emitting panel 100 is fixed: when all the partitions 10 are emitting light, the number of the emitting partitions 10 in the light-emitting panel 10 is the largest, which can improve the display effect of displaying delicate images; when displaying non-delicate images, using the signal line 20 to control some partitions 10 not to emit light can reduce power consumption while ensuring the display effect, and one partition 10 controls two or more light-emitting devices at the same time, so when one partition 10 is not emitting light, it can save the power consumption generated by controlling two or more light-emitting devices. In this embodiment, using the signal line 20 to control some partitions 10 not to emit light can greatly reduce power consumption.

[0059] Figure 4 for Figure 1 A schematic diagram of an operating mode of a light-emitting panel provided in an embodiment. Figure 4 A partition 10 filled with black indicates that the partition 10 does not emit light, or is in a dark state, and a partition 10 filled with a dot pattern indicates that the partition 10 emits light, or is in a bright state. The states of the partitions 10 in the following working mode diagrams are understood according to the above description.

[0060] Figure 4 The light-emitting state of the light-emitting panel 100 in the first working mode is illustrated. In the first working mode, at least one signal line 20 in the signal line group 2 controls the partition 10 connected thereto to be in a dark state, and at least one signal line 20 in the signal line group 2 controls the partition 10 connected thereto to be in a bright state. Figure 4 In the embodiment, n=2, and the signal line group 2 includes two signal lines 20, then one of the signal lines 20 controls the partition 10 connected thereto to be in a dark state, and the other signal line 20 controls the partition 10 connected thereto to be in a bright state. In the first working mode, only some of the partitions 10 in the light-emitting panel 100 emit light, and the distribution of the light-emitting partitions 10 in the entire light-emitting area of ​​the light-emitting panel 100 is relatively uniform. The light-emitting panel 100 provided in the embodiment of the present invention can be used as a backlight source for a liquid crystal display, or as a display panel for displaying an image. When the first working mode of the light-emitting panel 100 is used to display a non-delicate image, the light-emitting partitions 10 can be relatively evenly reduced when the number of partitions 10 set in the light-emitting panel 100 is fixed, which can reduce power consumption while ensuring the display effect.

[0061] Figure 5 for Figure 3 A schematic diagram of an operating mode of a light-emitting panel provided in an embodiment. Figure 5The light-emitting state of the light-emitting panel 100 in the first working mode is shown in FIG. 2 . The signal line group 2 includes two signal lines 20. One of the signal lines 20 is used to control the partition 10 connected thereto to be in a dark state, and the other signal line 20 is used to control the partition 10 connected thereto to be in a bright state. It can be seen that the connection method between the signal line 20 and the partition 10 in the embodiment of the present invention can relatively evenly reduce the partitions 10 that emit light in the entire light-emitting area in the first working mode, so that the partitions 10 that emit light in the first working mode are relatively evenly distributed in the entire light-emitting area, thereby reducing power consumption while ensuring the light-emitting effect of the entire surface of the light-emitting panel 100.

[0062] Figure 4 and Figure 5 In the embodiments, the first working mode of the light-emitting panel 100 is described with n=2. When n=2, the light-emitting panel 100 works in the first working mode, and the number of light-emitting sub-areas 10 accounts for half of the total number of sub-areas 10 in the light-emitting area. In other embodiments, n>2. For example, when n=3, the signal line group 2 includes 3 signal lines 20. In the first working mode: one signal line 20 can control the sub-area 10 connected thereto to be in a dark state, and the other two signal lines 20 can control the sub-areas 10 connected thereto to be in a bright state; or two signal lines 20 can control the sub-areas 10 connected thereto to be in a dark state, and the other signal line 20 can control the sub-areas 10 connected thereto to be in a bright state.

[0063] The light-emitting panel 100 provided in the embodiment of the present invention also includes a second working mode. In the second working mode, the signal line group 2 is used to control the subareas 10 connected thereto to emit light, that is, all the subareas 10 in the light-emitting panel 100 are in a bright state. In the second working mode, the light-emitting panel 100 is in a high-partition state, which means that the number of subareas 10 divided in the light-emitting panel 100 is large, and all the subareas 10 emit light during operation. In the second working mode, all subareas 10 set in the light-emitting panel 100 emit light. The second working mode of the light-emitting panel 100 is used to display delicate images, which can weaken the corner light of the image.

[0064] It can reduce display defects such as halo and improve the display effect of delicate images.

[0065] In some embodiments, the second partition rows 2H in the partition group 1 extend along the second direction b and are arranged along the first direction a, and the n partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the n second partition rows 2H. Figure 1As shown, when n=2, the partition group 1 includes two second partition rows 2H, and the two partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the two second partition rows 2H. In this embodiment, the partition group 1 consisting of n*n partitions 10 includes n first partition rows 1H extending along the first direction a and n second partition rows 2H extending along the second direction b. For one signal line 20, one partition 10 in each of the n second partition rows 2H is connected to the signal line 20. In other words, the n partitions 10 belonging to the same partition group 1 connected by one signal line 20 are respectively located in the n second partition rows 2H. In this embodiment, the n partitions 10 belonging to the same partition group 1 connected by one signal line 20 are located in at least two first partition rows 1H, and the n partitions 10 belonging to the same partition group 1 connected by one signal line 20 are located in n second partition rows 2H. Such an arrangement enables the n partitions 10 connected to the same signal line 20 in the partition group 1 to be relatively evenly distributed in the first direction a, which is the arrangement direction of the second partition row 2H in the partition group 1. This is conducive to improving the uniformity of the distribution of the n partitions 10 connected to the same signal line 20 in the partition group 1, and is also conducive to the relatively even distribution of the luminous partitions 10 in the entire luminous area in the first working mode. The first working mode is used to display non-delicate images, which can ensure the display effect and reduce power consumption.

[0066] In other embodiments, n=3. Figure 6 A schematic diagram of another light emitting panel provided by an embodiment of the present invention is shown in FIG. Figure 6 As shown, n=3, the partition group 1 consisting of 3*3 partitions 10 includes 3 first partition rows 1H extending along the first direction a and 3 second partition rows 2H extending along the second direction b, and the signal line group 2 includes 3 signal lines 20. The three partitions 10 connected to one signal line 20 in the partition group 1 are located in at least two first partition rows 1H, and the three partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in three second partition rows 2H.

[0067] Figure 7 for Figure 6 A schematic diagram of an operating mode of a light-emitting panel provided in an embodiment. Figure 7 The light emitting panel 100 is shown in a light emitting state in the first working mode. Figure 7 As shown, the signal line group 2 includes three signal lines 20, one of the three signal lines 20 controls the partition 10 connected thereto to be in a dark state, and the other two signal lines 20 of the three signal lines 20 control the partitions 10 connected thereto to be in a bright state. In this embodiment, the light-emitting panel 100 operates in the first operating mode, and the number of the light-emitting partitions 10 accounts for two-thirds of the total number of the partitions 10.

[0068] In another embodiment, n=3, the signal line group 2 includes three signal lines 20, two of the three signal lines 20 control the partitions 10 connected thereto to be in a dark state, and another signal line 20 of the three signal lines 20 controls the partitions 10 connected thereto to be in a bright state, which is not illustrated in the figure. In this embodiment, the light-emitting panel 100 operates in the first operating mode, and the number of the light-emitting partitions 10 accounts for one third of the total number of the partitions 10.

[0069] Figure 6 The embodiment shows a connection mode between the signal line group 2 and the partition group 1 when n=3, and the characteristics of the connection mode include: the n partitions 10 connected to a signal line 20 in the partition group 1 are located in at least two first partition rows 1H, and the n partitions 10 connected to a signal line 20 in the partition group 1 are respectively located in n second partition rows 2H. Figure 6 In the embodiment, the signal line group 2 includes three signal lines 20, wherein three partitions 10 belonging to the same partition group 1 connected by one signal line 20 are respectively located in three first partition rows 1H, and three partitions 10 belonging to the same partition group 1 connected by the other two signal lines 20 are located in two first partition rows 1H.

[0070] When n=3, the signal line group 2 and the partition group 1 may also have other connection modes. Figure 8 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig. 9 for Figure 8 A schematic diagram of a working mode of a light emitting panel provided in an embodiment, Fig. 9 FIG. 1 illustrates a light-emitting state of the light-emitting panel 100 in the first working mode. Figure 8 As shown, n=3, the signal line group 2 includes 3 signal lines 20, and the 3 signal lines 20 all meet the following conditions: the 3 partitions 10 belonging to the same partition group 1 connected by the signal lines 20 are located in at least two first partition rows 1H, and the 3 partitions 10 belonging to the same partition group 1 connected by the signal lines 20 are located in two second partition rows 2H. That is, the n signal lines 20 in the signal line group 2 need to be cross-connected to the n first partition rows 1H in the partition group 1.

[0071] In some embodiments, the first partition row 1H in the partition group 1 extends along the first direction a and is arranged along the second direction b, and the n partitions 10 connected to a signal line 20 in the partition group 1 are respectively located in the n first partition rows 1H. Such an arrangement enables the n partitions 10 connected to the same signal line 20 in the partition group 1 to be relatively evenly distributed in the second direction b, which is conducive to improving the distribution uniformity of the n partitions 10 connected to the same signal line 20 in the partition group 1 where they are located, and is also conducive to the relatively even distribution of the partitions 10 that emit light in the first working mode in the entire light-emitting area. Therefore, the first working mode is used to display non-delicate images, which can ensure the display effect while reducing power consumption.

[0072] When n = 2, such as Figure 4 As shown, two partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in two first partition rows 1H, and two partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in two second partition rows 2H.

[0073] When n=3, Fig.10 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig.11 for Fig.10 A schematic diagram of a working mode of a light emitting panel provided in an embodiment, Fig.11 FIG. 1 illustrates a light-emitting state of the light-emitting panel 100 in the first working mode. Fig.10 As shown, 3*3 partitions 10 constitute partition group 1, and signal line group 2 includes 3 signal lines. The three partitions 10 connected to one signal line 20 in partition group 1 are respectively located in three first partition rows 1H, and the three partitions 10 connected to one signal line 20 in partition group 1 are respectively located in three second partition rows 2H. Fig.10 In the embodiment, the connection between the signal line group 2 and the partition group 1 is different from Figure 6 and Figure 8 Example.

[0074] Fig.11 In the embodiment, in the first working mode, one of the three signal lines 20 controls the partition 10 connected thereto to be in a dark state, and the other two signal lines 20 of the three signal lines 20 control the partitions 10 connected thereto to be in a bright state. In another embodiment, Fig.10 In the first working mode of the light-emitting panel provided in the embodiment, two of the three signal lines 20 control the partitions 10 connected thereto to be in a dark state, and another signal line 20 of the three signal lines 20 controls the partition 10 connected thereto to be in a bright state, which is not illustrated in the figure here.

[0075] When n=4, Fig.12 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig.13 for Fig.12 A schematic diagram of a working mode of a light emitting panel provided in an embodiment, Fig.13 FIG. 1 illustrates a light-emitting state of the light-emitting panel 100 in the first working mode. Fig.12 As shown, 4*4 partitions 10 constitute a partition group 1, and the signal line group 2 includes 4 signal lines. The 4 partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the 4 first partition rows 1H, and the 4 partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the 4 second partition rows 2H.

[0076] Fig.13 In the embodiment, it is shown that in the first working mode, one of the four signal lines 20 controls the partition 10 connected thereto to be in a dark state, and the other three of the four signal lines 20 control the partitions 10 connected thereto to be in a bright state. It can be seen that the four partitions 10 in a dark state in a partition group 1 are relatively evenly distributed in the first direction a, and the four partitions 10 in a dark state in a partition group 1 are also relatively evenly distributed in the second direction b. Such a setting in the first working mode can relatively evenly reduce the luminous partitions 10 when the number of partitions 10 set in the light-emitting panel 100 is fixed, and the first working mode is used to display non-delicate images, which can reduce power consumption while ensuring display effects.

[0077] Fig.13 In the embodiment, in the first working mode, the number of luminous sub-areas 10 accounts for three quarters of the total number of sub-areas 10 in the luminous area, and the number of non-luminous sub-areas 10 accounts for one quarter of the total number of sub-areas 10 in the luminous area. Fig.12 For the light-emitting panel 100 provided in the embodiment, the subareas 10 connected thereto are uniformly controlled through the signal lines 20, so that the number of subareas 10 emitting light in the first working mode accounts for one quarter or one half of the total number of subareas 10 in the light-emitting area.

[0078] When n=4, Fig.14 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig.15 for Fig.14 A schematic diagram of a working mode of a light emitting panel provided in an embodiment, Fig.15 FIG. 1 illustrates a light-emitting state of the light-emitting panel 100 in the first working mode. Fig.14 As shown, 4*4 partitions 10 constitute a partition group 1, and the signal line group 2 includes 4 signal lines. The 4 partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the 4 first partition rows 1H, and the 4 partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the 4 second partition rows 2H. Fig.14 The connection method between signal line group 2 and partition group 1 is different from Fig.12 Example.

[0079] When n=5, Fig.16 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig.17 for Fig.16 A schematic diagram of a working mode of a light emitting panel provided in an embodiment, Fig.17 FIG. 1 illustrates a light-emitting state of the light-emitting panel 100 in the first working mode. Fig.16 As shown, 5*5 partitions 10 constitute a partition group 1, and the signal line group 2 includes 5 signal lines. The 5 partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the 5 first partition rows 1H, and the 5 partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the 5 second partition rows 2H.

[0080] When n=5, Fig.18 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig.19 for Fig.18 A schematic diagram of a working mode of a light emitting panel provided in an embodiment, Fig.19 FIG. 1 illustrates a light-emitting state of the light-emitting panel 100 in the first working mode. Fig.18 As shown, 5*5 partitions 10 constitute a partition group 1, and the signal line group 2 includes 5 signal lines. The 5 partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the 5 first partition rows 1H, and the 5 partitions 10 connected to one signal line 20 in the partition group 1 are respectively located in the 5 second partition rows 2H. Fig.18 The connection method between signal line group 2 and partition group 1 is different from Fig.16 Embodiment: When n=5, the signal line group 2 and the partition group 1 may be connected in other ways, which will not be illustrated here.

[0081] In some embodiments, Figure 1As shown, a plurality of partition groups 1 are repeatedly arranged in the first direction a to form a first partition group row 1H-1, and one first partition group row 1H-1 extending along the first direction a corresponds to one signal line group 2. Among them. Two partitions 10 adjacent to each other in the first direction a and belonging to two partition groups 1 respectively are connected to two different signal lines 20. Not only are n signal lines 20 in the signal line group 2 cross-connected to n first partition rows 1H in the partition group 1 within the partition group 1, but n signal lines 20 are also cross-connected to partitions 10 of different partition rows between adjacent partition groups 1. With such arrangement, when a signal line 20 is used to control the partition 10 connected thereto to be in a dark state in the first working mode, two partitions 10 adjacent to each other in the first direction a and belonging to two partition groups 1 respectively will not be in a dark state at the same time, which is conducive to making the partitions 10 in the dark state relatively dispersed and unconcentrated in the first direction a, so that the partitions 10 in the dark state are relatively evenly distributed, and thus the luminous partitions 10 in the light-emitting panel 100 are relatively evenly distributed.

[0082] In some embodiments, Figure 1 , Fig.10 , Fig.12 , Fig.14 , Fig.16 ,as well as Fig.18 , n partitions 10 connected to a signal line 20 in a partition group 1 are respectively located in n second partition rows 2H, n partitions 10 connected to a signal line 20 in a partition group 1 are respectively located in n first partition rows 1H, and two partitions 10 adjacent in the first direction a and belonging to two partition groups 1 are connected to two different signal lines 20. This arrangement enables a partition 10 and partitions 10 adjacent thereto in the first direction a and the second direction b to be connected to different signal lines 20. When a signal line 20 is used to control a partition 10 connected thereto to be in a dark state in the first working mode, two adjacent partitions 10 in the first direction a will not be in a dark state at the same time, and two adjacent partitions 10 in the second direction b will not be in a dark state at the same time, which is conducive to uniform distribution of the partitions 10 in the dark state in the entire light-emitting area, so that the luminous partitions 10 in the light-emitting panel 100 are relatively evenly distributed, and the light-emitting panel 100 can ensure the display visual effect when it is used as a backlight source or a display panel for display.

[0083] In some embodiments, each subarea 10 in the subarea group 1 includes the same number of light-emitting devices. Fig. 20 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig. 20 Taking n=2 as an example, the area where a partition group 1 is located is shown. Fig. 20As shown, two signal lines 20 in the signal line group 2 are cross-connected to two first partition rows 1H in the partition group 1, and each partition 10 in the partition group 1 includes four light-emitting devices 11, wherein the four light-emitting devices 11 in the partition 10 can be connected in parallel or in series. The number of light-emitting devices 11 included in the partition 10 can also be 1, 6 or 8, which is not illustrated in the figure.

[0084] In some other embodiments, at least two of the n sub-areas 10 connected to one signal line 20 in the sub-area group 1 include different numbers of light-emitting devices. Fig.21 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig.21 Taking n=2 as an example, the area where a partition group 1 is located is shown. Fig.21 As shown, two signal lines 20 in the signal line group 2 are cross-connected to two first partition rows 1H in the partition group 1, and one signal line 20 connects two partitions 10 belonging to the same partition group 1, and one of the two partitions 10 includes four light-emitting devices 11 and the other includes six light-emitting devices 11.

[0085] Fig. 22 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig. 22 The control method of a partition 10 is shown as follows: Fig. 22 As shown, the light-emitting panel 100 includes a partition control circuit 30, and row selection lines 40 and data lines 50 whose extension directions intersect each other. The light-emitting devices 11 in the partition 10 are connected to the partition control circuit 30. The partition control circuit 30 is used to control the partition 10. The embodiment of the present invention does not limit the specific structure of the partition control circuit 30. The partition control circuit 30 includes at least one thin film transistor. The row selection line 40 and the data line 50 are respectively connected to the partition control circuit 30. The row selection line 40 is used to provide an enable signal to control the partition control circuit 30 to turn on. The data line 50 is used to provide a data signal to the partition control circuit 30 to control the light-emitting brightness of the partition 10.

[0086] In some embodiments, the signal line 20 is a row gate line. Fig.23 A schematic diagram of another light-emitting panel provided by an embodiment of the present invention, Fig.23 Take n=2 as an example, Fig.23As shown, the light-emitting panel 100 includes two shift drive circuits 60, namely, a shift drive circuit 60-1 and a shift drive circuit 60-2. The shift drive circuit 60 includes a plurality of cascaded shift registers 61; for one shift drive circuit 60, when the shift drive circuit 60 is working, the plurality of cascaded shift registers 61 sequentially output scanning signals. The signal line 20 is a row selection line 40, and the row selection line 40 is electrically connected to the shift drive circuit 60. The row selection line 40 extends along a first direction a, and the light-emitting panel 100 also includes a data line ( Fig.23 (not shown). When n=2, the signal line group 2 includes two row gate lines 40, and the two row gate lines 40 in the signal line group 2 are connected to two shift drive circuits 60. That is, one row gate line 40 in the signal line group 2 is connected to the shift drive circuit 60-1, and the other row gate line 40 is connected to the shift drive circuit 60-2.

[0087] In the light-emitting panel 100, the partition 10 is connected to the shift drive circuit 60 through the signal line 20. The shift drive circuit 60 can uniformly control the multiple partitions 10 connected thereto. For example, if the shift drive circuit 60 does not work, the multiple partitions 10 connected thereto do not work, that is, the partition 10 is in a dark state (or is called non-luminous). Fig.23 In the embodiment, the shift driving circuit 60-1 does not work so that the partition 10 connected thereto is in a dark state, and the shift driving circuit 60-2 works to control the partition 10 connected thereto to be in a bright state, so that the light emitting panel 100 can work in Figure 4 Illustrated first operating mode.

[0088] Take n=3 as an example, Fig.24 A schematic diagram of another light emitting panel provided by an embodiment of the present invention is shown in FIG. Fig.24 As shown, when n=3, the light emitting panel 100 includes three shift drive circuits 60, namely, a shift drive circuit 60-1, a shift drive circuit 60-2 and a shift drive circuit 60-3, and the shift drive circuit 60 includes a plurality of cascaded shift registers 61. The signal line 20 is a row gate line 40, and the signal line group 2 includes three row gate lines 40, one row gate line 40 in the signal line group 2 is connected to the shift drive circuit 60-1, one row gate line 40 is connected to the shift drive circuit 60-2, and another row gate line 40 is connected to the shift drive circuit 60-3. Fig.24 In the embodiment, the shift driving circuit 60-1 does not work to control the partition 10 connected thereto to be in a dark state, and the shift driving circuit 60-2 and the shift driving circuit 60-3 both work, so that the light emitting panel 100 can work in Fig.11 Illustrated first operating mode.

[0089] In some embodiments of the present invention, the signal line 20 is a row gate line 40, and n shift drive circuits 60 are provided in the light-emitting panel 100, and n signal lines 20 (i.e., row gate lines 40) in the signal line group 2 are correspondingly connected to the n shift drive circuits 60. When multiple partition groups 1 and multiple signal line groups 2 are provided in the light-emitting panel 100, the shift drive circuit 60 uniformly controls the working states of multiple partitions 10 through the signal lines 20 connected thereto, and the control method is simple. Combined with the connection method in which the n signal lines 20 in the signal line group 2 are cross-connected to the n first partition rows 1H in the partition group 1, the partition 10 controlled by a shift drive circuit 60 can be relatively uniformly partitioned in the entire light-emitting area of ​​the light-emitting panel 100. When a shift drive circuit 60 is not working, the luminous partitions 10 in the entire light-emitting area can be relatively uniformly reduced, and accordingly, the luminous partitions 10 are relatively uniformly distributed in the entire light-emitting area, and the display effect when displaying non-delicate images is ensured while reducing power consumption.

[0090] When the signal line 20 is a row selection line 40, the light-emitting panel 100 includes n shift drive circuits 60. In the first working mode, at least one of the n shift drive circuits 60 does not work so that the signal line 20 controls the partition 10 connected thereto to be in a dark state, and at least one of the n shift drive circuits 60 works so that the signal line 20 controls the partition 10 connected thereto to be in a bright state. The first working mode of the light-emitting panel 100 is realized by controlling the working state of the shift drive circuit 60, and the control method is simple. In addition, the first working mode can cooperate with the display of non-delicate images, and can reduce power consumption while ensuring the display effect.

[0091] Taking n=3 as an example, combined with Fig.24 In the embodiment, two of the three shift driving circuits 60 work and the other one does not work, which can present Fig.11 Indicates the lighting state, Fig.11 In the illustrated first working mode, the non-luminous subareas 10 in the light-emitting panel 100 account for one third of the total number of subareas 10. In other embodiments, Fig.24 The first working mode of the light emitting panel 100 provided in the embodiment may also be that two of the three shift driving circuits 60 are not working and the other one is working. In this case, in the first working mode, the non-luminous subareas 10 in the light emitting panel 100 account for two thirds of the total number of subareas 10 .

[0092] When n=4 or 5, when the signal line 20 is a row selection line, the connection method between the signal line 20 in the signal line group 2 and the shift register circuit 60 can refer to Fig.23 , Fig.24 For understanding of the embodiments, no further illustration is given here.

[0093] In some embodiments, Fig.23 and Fig.24 As shown, a plurality of partition groups 1 are arranged along the second direction b, and a plurality of signal line groups 2 are arranged along the second direction b; two partitions 10 adjacent in the second direction b and belonging to two partition groups 1 respectively are connected to two different shift driving circuits 60. In this arrangement, when the partition 10 connected thereto is controlled to be in a dark state by the working state of the shift driving circuit 60 in the first working mode, the two partitions 10 adjacent in the second direction b and belonging to two partition groups 1 respectively will not be in a dark state at the same time, which is conducive to making the partitions 10 in the dark state relatively dispersed and unconcentrated in the second direction b, so that the partitions 10 in the dark state are evenly distributed, thereby ensuring the brightness uniformity of the light-emitting panel 100 as a surface light source.

[0094] In one embodiment, Fig.25 is a schematic diagram of a light-emitting panel in the related art. Fig.26 for Fig.25 A schematic diagram of a working mode of a light-emitting panel in the related art. Fig.25 As shown, the light-emitting panel 100 includes a plurality of partitions 10 arranged in an array, wherein the plurality of partitions 10 are arranged into partition columns 10L in a first direction a, and the plurality of partitions 10 are arranged into partition rows 10H in a second direction b. The data line 50 extends along the first direction a, and the row selection line 40 extends along the second direction b. The plurality of partitions 10 located in the same partition column 10L are connected to the same data line 50, and the partitions 10 located in the same partition row 10H are connected to the same row selection line 40. In this embodiment, one data line 50 controls one partition column 10L. When the data line 50 alternately provides dark state signals and bright state signals to the plurality of partitions 10 on one partition column 11, the number of luminous partitions 10 on one partition column 11 can be halved. When each data line 50 alternately provides dark state signals and bright state signals to the plurality of partitions 10 on the partition column 11, the light-emitting panel 100 can be in a state of Fig.26 Indicates the lighting status. Fig.26 In the embodiment, the number of the light-emitting subareas 10 accounts for half of the total number of the subareas 10 , and the light-emitting subareas 10 are evenly distributed in the entire light-emitting area of ​​the light-emitting panel 100 . Fig.26 Although the luminous state of the embodiment can reduce the number of luminous partitions 10, this luminous state requires frequent switching of dark state signals and bright state signals on the data line 50, which places high demands on the driver chip. When the number of partitions 10 connected to the data line 50 is large, the driver chip is difficult to meet the requirements.

[0095] In order to reduce the number of illuminated subareas 10 and reduce the requirements on the driver chip, the embodiment of the present invention provides another light-emitting panel. The data lines are grouped and the data lines in the group are crossed to connect with the subareas 10. Fig. 27Another schematic diagram of a light emitting panel provided by an embodiment of the present invention, taking n=2 as an example, Fig. 27 As shown, the light emitting panel 100 includes a data line 50 extending along a first direction a and a row selection line 40 extending along a second direction b, and the signal line 20 is a data line 50, and the signal line group 2 includes two data lines 50. The two data lines 50 in the signal line group 2 are cross-connected to two first partition rows 1H in the partition group 1, and the two partitions 10 belonging to the same partition group 1 connected to the data line 50 are respectively located in two second partition rows 2H. The light emitting panel 100 also includes a plurality of data terminals ( Fig. 27 The data line 50 is coupled to the data terminal, the data terminal is connected to the driving chip, and the driving chip provides a data signal to the data line 50 through the data terminal. The data terminal is a pad provided on the light-emitting panel. In some embodiments, the data line 50 is electrically connected to the data terminal through a conductive trace; in other embodiments, a multiplexer is provided in the light-emitting panel, the data line 50 is electrically connected to the data terminal through the multiplexer, and one multiplexer connects at least two data lines 50.

[0096] Fig.28 for Fig. 27 A schematic diagram of a working mode of a light emitting panel provided in an embodiment, Fig.28 Schematic diagram of the first working mode of the light emitting panel. Fig.28 It can be seen that for one signal line group 2, the partitions 10 connected to one data line 50 in the signal line group 2 are all in the dark state, and the partitions 10 connected to another data line 50 in the signal line group 2 are all in the bright state. The data line 50 provides a continuous dark state signal to control the multiple partitions 10 connected thereto to be in the dark state, and the data line 50 provides a continuous data signal (or called a bright state signal) to control the multiple partitions 10 connected thereto to be in the bright state. Fig.28 In the luminous state, the number of luminous partitions 10 accounts for half of the total number of partitions 10, which can reduce power consumption, and the luminous partitions 10 are evenly distributed in the entire luminous area of ​​the luminous panel 100, ensuring the uniformity of overall brightness. In this embodiment, the luminous panel 100 cooperates with displaying non-delicate images in the first working mode, which can ensure the display effect and reduce power consumption. Moreover, when the luminous panel 100 works in the first working mode, there will be no frequent jumps between the bright state signal and the dark state signal on the data line 50, which can reduce the requirements for the driver chip and is easy to implement.

[0097] In the embodiment where the signal line 20 is a data line, when the light-emitting panel 100 operates in the first operating mode: m signal lines 20 in the signal line group 2 provide dark state signals to control the partition 10 connected thereto to be in a dark state, and nm signal lines 20 in the signal line group 2 provide data signals to control the partition 10 connected thereto to be in a bright state, where m is a positive integer, and m <n。

[0098] Take n=2 as an example, Fig.28 As shown, the signal line group 2 includes two data lines 50. In the first working mode, one data line 50 in the signal line group 2 provides a dark state signal to control the partition 10 connected thereto to be in a dark state, and the other data line 50 in the signal line group 2 provides a data signal to control the partition 10 connected thereto to be in a bright state.

[0099] When n=3, m=1 or 2. Fig.29 A schematic diagram of another working mode of a light emitting panel provided by an embodiment of the present invention is shown in FIG. Fig.29 As shown, the signal line 20 is a data line 50, n=3. The signal line group 2 includes three data lines 50, Fig.29 The row gate lines extending along the second direction b are not shown. Fig.29 In the illustrated first working mode, one data line 50 in the signal line group 2 provides a dark state signal to control the partition 10 connected thereto to be in a dark state, and the other two data lines 50 in the signal line group 2 provide data signals to control the partitions 10 connected thereto to be in a bright state. In this embodiment, m=1, and the number of partitions 10 in the dark state in the first working mode is one third of the total number of partitions 10. In other embodiments, m=2, and the number of partitions 10 in the dark state in the first working mode is two thirds of the total number of partitions 10, which is not illustrated in the figure.

[0100] In some embodiments, Fig. 27 As shown, a plurality of partition groups 1 are arranged in the second direction b, and the partitions 10 arranged along the second direction b in the partition group 1 are connected to a row gate line 40, and a plurality of row gate lines 40 are arranged along the first direction a. The light-emitting panel 100 includes a shift drive circuit 60, and the shift drive circuit 60 includes a plurality of cascaded shift registers 61, and a plurality of row gate lines 40 are connected to the same shift drive circuit 60. In this embodiment, a shift drive circuit 60 is used to cooperate with the data line 50 to drive the partition 10, and the control method is simple. The number of partitions 10 is not limited by the number of channels of the driving chip, and a relatively large number of partitions 10 can be set in the light-emitting panel 100. When all the partitions 10 are luminous, the display effect of the light-emitting panel 100 in displaying delicate images can be improved. In addition, when the light-emitting panel 100 cooperates to display non-delicate images, the light-emitting panel 100 is controlled to work in the first working mode, which can reduce power consumption while ensuring the display effect of non-delicate images.

[0101] In some embodiments, the signal line 20 is a data line, n=2, and in the first working mode: one of the odd-numbered signal lines and the even-numbered signal lines provides a dark state signal to control the partition 10 connected thereto to be in a dark state, and the other provides a data signal to control the partition 10 connected thereto to be in a bright state. In this way, in the first working mode, the number of the partitions 10 that emit light accounts for half of the total number of the partitions 10, which can reduce power consumption and make the partitions 10 that emit light evenly distributed in the light-emitting area of ​​the light-emitting panel 100.

[0102] When the signal line 20 is a data line 50, n data lines 50 in the signal line group 2 are cross-connected to the partition 10 in the partition group 1, and the odd-numbered data lines and the even-numbered data lines are distinguished in the second direction b in the following manner: Fig.28 Take this as an example to illustrate.

[0103] like Fig.28 As shown, the partition array formed by the partitions 10 includes a partition row 10H extending along the second direction b, and a plurality of partitions 10 are arranged along the second direction b in the partition row 10H. The odd data lines 50-1 and the even data lines 50-2 can be determined according to the partition row 10H located at the end position in the first direction a. Fig.28 Taking the partition row 10H at the upper and lower end positions in the first direction a as an example, the arrangement order of the data lines 50 is defined to be the same as the arrangement order of the partitions 10 in the partition row 10H at the end position. That is, the data line 50 connected to the odd-numbered partitions 10 in the partition row 10H at the end position is the odd-numbered data line 50-1, and the data line 50 connected to the even-numbered partitions 10 in the partition row 10H at the end position is the even-numbered data line 50-2.

[0104] The above embodiment shows that for a row gate line 40, only one end thereof is connected to a shift driving circuit 60. In other embodiments, for a row gate line 40, both ends thereof are connected to the shift driving circuit 60. Fig.30 A schematic diagram of another light emitting panel provided by an embodiment of the present invention is shown in FIG. Fig.30As shown, the light-emitting panel includes a row selection line 40 extending along a first direction a and a data line 50 extending along a second direction b. Taking n=2 as an example, the partition group 1 includes 2*2, a total of 4 partitions 10, and the signal line group 2 includes 2 signal lines 20, and the signal line 20 is a row selection line 40. The shift drive circuit 60 includes a shift drive circuit 60-1 and a shift drive circuit 60-2. The two shift drive circuits 60-1 are respectively arranged on the left and right sides of the partition array in the first direction a, and the two shift drive circuits 60-1 transmit the same signal; the two shift drive circuits 60-2 are respectively arranged on the left and right sides of the partition array in the first direction a, and the two shift drive circuits 60-2 transmit the same signal. The two ends of a row selection line 40 in the signal line group 2 are respectively connected to the two shift drive circuits 60-1, and the two ends of another row selection line 40 are respectively connected to the two shift drive circuits 60-2. In this embodiment, both ends of the row gate line 40 are connected to the shift drive circuit 60, and the row gate line 40 is driven by a bilateral drive method. In a horizontal light-emitting panel, the length of the row gate line 40 in its extension direction is greater than the length of the data line 50 in its extension direction. The row gate line 40 is driven by a bilateral drive method, which can reduce the voltage drop difference at various positions of the row gate line 40. When the expected brightness of each sub-area 10 connected to the row gate line 40 is the same brightness, the voltage drop on the row gate line 40 will cause the actual brightness of each sub-area 10 to be different. The bilateral drive method can improve the brightness difference between the sub-areas 10 connected to the row gate line 40 caused by the voltage drop. Fig.30 In the embodiment, both the two shift driving circuits 60-1 and the two shift driving circuits 60-2 are working so that all the partitions 10 in the light-emitting panel are luminous, which can cooperate to display delicate images. When both the shift driving circuits 60-1 are not working and the two shift driving circuits 60-2 are working, the number of luminous partitions 10 in the light-emitting panel can be reduced, and the power consumption can be reduced to cooperate to display non-delicate images.

[0105] Fig.30 The embodiment shows that the shift drive circuit 60-1 is located on the side of the shift drive circuit 60-2 close to the partition array on both the left and right sides of the light emitting panel 100. In other words, the shift drive circuit 60-2 is closer to the edge of the light emitting panel 100 than the shift drive circuit 60-1. In other embodiments, for example, the shift drive circuit 60-2 is arranged on one side of the light emitting panel 100 closer to the edge of the light emitting panel 100 than the shift drive circuit 60-1, and the shift drive circuit 60-1 is arranged on the other side of the light emitting panel 100 closer to the edge of the light emitting panel 100 than the shift drive circuit 60-2. In the scheme of setting multiple shift drive circuits, the present invention does not limit the relative position of each shift drive circuit.

[0106] Fig.30The embodiment takes the signal line 20 as a row gate line 40 as an example. In the embodiment where the signal line 20 is a data line, Fig. 27 As shown in FIG. 1 , one end of a row selection line 40 is connected to a shift register 61. In other embodiments, the signal line 20 is a data line, and two shift drive circuits 60 are provided in the light emitting panel 100, that is, one shift drive circuit 60 is connected to each of the two ends of a row selection line 40, and this embodiment can also be applied to a horizontal light emitting panel.
