Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to an array substrate, a pixel arrangement structure, a display panel and a display device. BACKGROUND

[0002] With the continuous development of display technology, Micro LED (Micro Light Emitting Diode) display panel has incomparable advantages in terms of light emitting power, power consumption, contrast, response speed, and service life.

[0003] At present, in the preparation process of Micro LED, the arrayed chips need to be transferred and bonded to the target substrate. In the process of chip transfer, a large number of redundant bits need to be reserved on the target substrate to repair the bad chips. However, the existence of a large number of redundant bits affects the display effect of the display device. SUMMARY

[0004] Therefore, it is necessary to provide an array substrate, a pixel arrangement structure, a display panel and a display device, which aims to solve the technical problem that a large number of redundant bits exist in the preparation process of Micro LED, affecting the display effect of the display device.

[0005] In a first aspect, an array substrate is provided, which includes a plurality of pad groups, the pad groups being used to connect light emitting devices, the light emitting devices including a plurality of sub-pixels; each pad group includes a plurality of main pads and at least one redundant pad; the plurality of main pads are respectively used to connect different sub-pixels, and the redundant pad is configured to repair the corresponding abnormal pad when the main pad is abnormal, and is electrically connected with the pixel driving circuit corresponding to the abnormal pad; wherein in the same pad group, the number of redundant pads is less than the number of main pads.

[0006] In a second aspect, a pixel arrangement structure is also provided, which includes a plurality of pixel groups, each pixel group including a plurality of sub-pixels and at least one redundant sub-pixel; the redundant sub-pixel is used to emit light of a corresponding color when the sub-pixel is abnormal; the redundant sub-pixel is configured to repair the corresponding abnormal sub-pixel when the sub-pixel is abnormal, and is electrically connected with the pixel driving circuit corresponding to the abnormal sub-pixel; wherein in the same pixel group, the number of redundant sub-pixels is less than the number of sub-pixels.

[0007] In a third aspect, a display panel is also provided, which includes the array substrate provided in the first aspect or the pixel arrangement structure provided in the second aspect.

[0008] In a fourth aspect, a display device is also provided, which includes the display panel provided in the third aspect.

[0009] The array substrate provided in this application embodiment has multiple pad groups on it, and multiple main pads and at least one redundant pad in each pad group. When a main pad malfunctions, the corresponding malfunctioning pad is repaired by the redundant pad, thereby allowing the sub-pixel to emit light of the corresponding color normally again. Since the number of redundant pads in the same pad group is less than the number of main pads, it is not necessary to reserve a large number of redundant bits on the array substrate to repair faulty chips during chip transfer. This reduces the impact of redundant bits on the display effect of the display device, thereby increasing the pixel density and improving the display effect of the display device.

[0028] In order to facilitate the understanding of the present application, a more comprehensive description of the present application will be made with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0030] In describing a position relationship, unless otherwise defined, when an element, such as a layer, a film or a substrate, is referred to as "on" another element, it can be directly on the other element or an intervening element can also be present. Further, when a layer is referred to as "under" another layer, it can be directly under the other layer or one or more intervening elements can also be present. It can also be understood that when a layer is referred to as "between" two layers, it can be the only layer between the two layers or one or more intervening elements can also be present.

[0032] It should be understood that although the terms "first", "second" and the like can be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element can be called a second element, and similarly, a second element can be called a first element without departing from the scope of the present application.

[0033] It should also be understood that, in interpreting elements, although not explicitly described, the element is interpreted to include an error range that should be within an acceptable deviation range of a specific value determined by a person skilled in the art. For example, "about", "approximately" or "essentially" can mean within one or more standard deviations, without limitation.

[0034] Furthermore, in the specification, the phrase "plan view schematic diagram" refers to a figure when the target portion is viewed from above, and the phrase "cross-sectional schematic diagram" refers to a figure when a section is taken by cutting the target portion vertically and viewed from the side.

[0035] In addition, the drawings are not drawn to scale 1:1, and the relative sizes of the elements are only drawn by example in the drawings, not necessarily in true proportion.

[0036] As in the background section, the micro LED in the related art needs to transfer and bond the arrayed chip to the target substrate in the preparation process. However, in the process of chip transfer, the number of chips that need to be transferred is extremely large, and mass transfer of chips will occur. Due to the yield of mass transfer, a large number of chips will be damaged during the transfer process, and the damaged chips need to be replaced with new undamaged chips. Before replacing the new undamaged chip, the damaged chip needs to be removed, and in the process of removing the damaged chip, the main pads on the target substrate connected to the chip will be damaged simultaneously. Therefore, a large number of redundant bits need to be reserved on the target substrate to repair the damaged chips. However, the existence of a large number of redundant bits affects the display effect of the display device.

[0037] Based on the above technical problems, the inventors found that the chip includes green light chips, blue light chips, and red light chips, and the red light chip is more fragile than the green light chip and the blue light chip. In the process of chip transfer, the mass transfer yield of the red light chip is less than that of the green light chip and the blue light chip, that is, the red light chip is more likely to be damaged in the process of chip transfer.

[0038] It should be noted that the chip referred to in the present application is a sub-pixel connected with the main pad in the present application. The sub-pixel includes a green sub-pixel, a blue sub-pixel and a red sub-pixel, which respectively emit green light, blue light and red light, the green sub-pixel is the first sub-pixel in the present application, the blue sub-pixel is the second sub-pixel in the present application, and the red sub-pixel is the third sub-pixel in the present application, that is, the first sub-pixel in the present application is a green light chip, the second sub-pixel in the present application is a blue light chip, and the third sub-pixel in the present application is a red light chip.

[0039] Further, based on the above research, the inventors designed the array substrate, the pixel arrangement structure, the display panel and the display device of the present application by changing the number of redundant bits, i.e. the number of redundant pads in the present application, and changing the position of the redundant pad compared with the main pad connecting the first sub-pixel, the second sub-pixel and the third sub-pixel, so as to reduce the influence of the redundant bit on the display effect of the display device, and further improve the pixel density of the display device, and improve the display effect of the display device.

[0040] The above is the core idea of the present application, and the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] As shown in Figure 1 and Figure 2 The array substrate 1 provided by the embodiments of the present application includes a plurality of pad groups 11, the pad group 11 is used to connect a light emitting device, the light emitting device includes a plurality of sub-pixels 12; the pad group 11 includes a plurality of main pads 111 and at least one redundant pad 112; the plurality of main pads 111 are respectively used to connect different sub-pixels 12, the redundant pad 112 is configured to repair the corresponding abnormal pad when the main pad 111 is abnormal, and is electrically connected with the pixel driving circuit corresponding to the abnormal pad; wherein in the same pad group 11, the number of redundant pads 112 is less than the number of main pads 111.

[0042] It should be noted that the plurality of sub-pixels 12 are configured to emit light of the same color or emit light of different colors, and the color of the light emitted by the sub-pixel 12 is not limited here.

[0043] Specifically, the pad group 11 includes a plurality of main pads 111 and at least one redundant pad 112, that is, in the preparation process of the Micro LED, the light emitting device needs to be transferred and bonded to the array substrate, and in the process of transferring the light emitting device, part of the light emitting device will be damaged. At this time, the damaged light emitting device needs to be removed. It can be understood that, since the main pad 111 is connected to the light emitting device, in the process of removing the light emitting device, the main pad 111 connected with the light emitting device will be damaged, and the redundant pad 112 needs to be reserved to repair the damaged main pad 111. Wherein, the plurality of main pads 111 are respectively used to connect different sub-pixels 12, when the main pad 111 is abnormal, the redundant pad 112 is used to repair the corresponding abnormal pad and is electrically connected with the pixel driving circuit corresponding to the abnormal pad, and then controls the corresponding sub-pixel 12 to normally emit light of the corresponding color.

[0044] Further, when the main pad 111 is not abnormal, the redundant pad 112 is not electrically connected with the pixel driving circuit, at this time, the redundant pad 112 does not affect the main pad 111. When the main pad 111 is abnormal, the redundant pad 112 is bonded to the side close to the bad point for repair, and the overflow of the bonding metal is used to repair the corresponding abnormal pad, so as to realize the electrical connection of the pixel driving circuit corresponding to the abnormal pad and realize the repair of the abnormal pad.

[0045] Since the number of the redundant pads 112 is less than the number of the main pads 111, in the process of repairing the abnormal pad by the redundant pad 112, the number of the redundant pads 112 can be reduced, and then the space occupied by the redundant pads 112 can be reduced, and then the space occupied by the redundant pads 112 in the display panel 10 and the display device 100 can be reduced, the pixel density of the display device 100 can be improved, and the display effect of the display device 100 can be improved.

[0046] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , the main pad 111 includes at least one first pad 1111, at least one second pad 1112 and at least one third pad 1113; the sub-pixel 12 includes a first sub-pixel 121, a second sub-pixel 122 and a third sub-pixel 123; the first pad 1111 is used to connect the first sub-pixel 121, the second pad 1112 is used to connect the second sub-pixel 122, and the third pad 1113 is used to connect the third sub-pixel 123; the redundant pad 112 is configured to repair the corresponding abnormal pad when the first pad 1111, the second pad 1112 and the third pad 1113 are abnormal, and is electrically connected with the pixel driving circuit corresponding to the abnormal pad; wherein, in the same pad group 11, the number of the redundant pads 112 is less than the sum of the number of the first pads 1111, the second pads 1112 and the third pads 1113.

[0047] The first pad 1111 is used to connect the first sub-pixel 121, the second pad 1112 is used to connect the second sub-pixel 122, and the third pad 1113 is used to connect the third sub-pixel 123. Thus, the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 can be driven by the pixel driving circuit to emit light of the corresponding color, and the sub-pixel 12 can be individually driven and controlled by the pixel driving circuit connected to the main pad 111.

[0048] Furthermore, by setting redundant pads 112, and making the number of redundant pads 112 less than the sum of the number of the first pad 1111, the second pad 1112 and the third pad 1113, the number of redundant pads 112 can be reduced during the process of repairing abnormal pads with redundant pads 112. This reduces the space occupied by redundant pads 112, thereby reducing the space occupied by redundant pads 112 in the display panel 10 and the display device 100, increasing the pixel density of the display device 100, and improving the display effect of the display device 100.

[0049] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the first pad 1111 and the second pad 1112 are respectively disposed on both sides of the redundant pad 112; there are multiple third pads 1113, some of which are disposed on the side of the first pad 1111 away from the redundant pad 112, and the remaining third pads 1113 are disposed on the side of the second pad 1112 away from the redundant pad 112.

[0050] Because the mass transfer yield of the third sub-pixel 123 is lower than that of the first sub-pixel 121 and the second sub-pixel 122 during the mass transfer process, the third sub-pixel 123 is more likely to be damaged than the first sub-pixel 121 and the second sub-pixel 122 during the mass transfer process.

[0051] Thus, since part of the third pads 1113 are arranged on the side of the first pad 1111 away from the redundant pad 112, and the rest of the third pads 1113 are arranged on the side of the second pad 1112 away from the redundant pad 112, when part of the third pads 1113 are abnormal, on the one hand, the rest of the third pads 1113 can be directly used to drive the corresponding third sub-pixel 123 to emit light of the corresponding color, so as to ensure the normal light emission of the third sub-pixel 123. On the other hand, the abnormal part of the third pads 1113 and the rest of the normal third pads 1113 can be connected in series, so that the normal third pads 1113 can be used to repair the abnormal third pads 1113, and the metal overflow can be used to repair the abnormal part of the third pads 1113, so as to ensure the normal light emission of the third sub-pixel 123.

[0052] It can be understood that when the first pad 1111 or the second pad 1112 is abnormal, the redundant pad 112 can be directly used to repair the abnormal first pad 1111 or the second pad 1112 by bonding on the side close to the bad point, and the metal overflow can be used to repair the abnormal first pad 1111 or the second pad 1112. Of course, when the first pad 1111 and the second pad 1112 are both abnormal, since the first pad 1111 and the second pad 1112 are arranged on the two sides of the redundant pad 112, the redundant pad 112 can be used to repair the first pad 1111 and the second pad 1112.

[0053] Since only one redundant pad 112 is needed in one pad group 11, the space occupied by the redundant pad 112 can be reduced, so as to improve the pixel density of the display device 100 and improve the display effect of the display device 100.

[0054] Alternatively, as shown in Figure 6 , the two third pads 1113 can be electrically connected, or the corresponding third sub-pixel 123 can be driven separately.

[0055] In some embodiments, as shown in Figure 7 , Figure 8 and Figure 9As shown, the pad group 11 includes two sub-groups, each of which includes a first pad 1111, a second pad 1112, at least two third pads 1113, and a redundant pad 112; the first pad 1111 and the second pad 1112 are respectively arranged on two sides of the redundant pad 112; part of the third pads 1113 are arranged on the side of the first pad 1111 away from the redundant pad 112, and the rest of the third pads 1113 are arranged on the side of the second pad 1112 away from the redundant pad 112; the first pad 1111 of one sub-group is electrically connected to the redundant pad 112 of the sub-group, and the second pad 1112 of the other sub-group is electrically connected to the redundant pad 112 of the sub-group.

[0056] In this way, if the third pad 1113 is abnormal, since the number of the third pads 1113 is multiple, and the multiple third pads 1113 are all away from the redundant pad 112, the arrangement of the third pads 1113 is similar to that in the above embodiment. Therefore, when the third pad 1113 of the present embodiment is abnormal, the repair bonding is performed in a similar way to that in the above embodiment, which will not be described here.

[0057] If the first pad 1111 or the second pad 1112 is abnormal, for the convenience of description, exemplarily, when the first pad 1111 is abnormal, since the first pad 1111 of one sub-group is electrically connected to the redundant pad 112 of the sub-group, and the second pad 1112 of the other sub-group is electrically connected to the redundant pad 112 of the sub-group, by directly connecting the redundant pad 112 electrically connected to the first pad 1111 with the first sub-pixel 121, and disconnecting the connection between the second pad 1112 and the redundant pad 112, the redundant pad 112 is also electrically connected to the first sub-pixel 121 in the sub-group, thereby realizing the repair of the first pad 1111, facilitating the backfilling process of the first pad 1111 during repair, and facilitating the repair of the first pad 1111.

[0058] Similarly, the position of the second pad 1112 and the redundant pad 112 is similar to that of the first pad 1111 and the redundant pad 112, and the repair is performed in the same way as the repair of the first pad 1111, which will not be described here.

[0059] Since there are at least 8 main pads 111 and at least 2 redundant pads 112 in one pad group 11, the space occupied by the redundant pads 112 can be greatly reduced, thereby further improving the pixel density of the display device 100 and further improving the display effect of the display device 100.

[0060] Alternatively, the two third pads 1113 can be electrically connected, or the corresponding third sub-pixels 123 can be separately driven.

[0061] In some embodiments, such as Figure 8 and Figure 9 As shown, in any subgroup, the distance between the center of the first pad 1111 and the center of the redundant pad 112 is not equal to the distance between the center of the second pad 1112 and the center of the redundant pad 112.

[0062] Thus, for example, the first pad 1111 is electrically connected to the redundant pad 112, and the second pad 1112 is not connected to the redundant pad 112. If the first pad 1111 malfunctions, since the first pad 1111 is electrically connected to the redundant pad 112, it is only necessary to electrically connect the redundant pad 112 to the first sub-pixel 121. This allows the first sub-pixel 121 to be driven to re-emulate the corresponding color of light normally through the pixel driving circuit corresponding to the first pad 1111. In another subgroup, by disconnecting the connection between the second pad 1112 and the redundant pad 112, and then connecting the first sub-pixel 121 to the redundant pad 112, the repair of the first pad 1111 can be achieved.

[0063] Furthermore, since the distance between the center of the first pad 1111 and the center of the redundant pad 112 in any subgroup is not equal to the distance between the center of the second pad 1112 and the center of the redundant pad 112, the distance between the first pad 1111 and the second pad 1112 relative to the redundant pad 112 can be changed, thereby further reducing the space occupied by the redundant pad 112, thereby further increasing the pixel density of the display device 100, and further improving the display effect of the display device 100.

[0064] In some embodiments, such as Figure 10 As shown, the pad group 11 includes two redundant pads 112, namely a first redundant pad 1121 and a second redundant pad 1122. The first pad 1121 and the second pad 1122 are respectively disposed on both sides of the first redundant pad 1121; the second redundant pad 1122 is disposed on the side of the first pad 1121 away from the first redundant pad 1121; and the third pad 1113 is disposed on the side of the second redundant pad 1122 away from the first pad 1111.

[0065] Thus, since the first pad 1111 and the second pad 1112 are respectively located on both sides of the first redundant pad 1121, when the first pad 1111 and / or the second pad 1112 malfunctions, the malfunctioning first pad 1111 and / or second pad 1112 can be repaired by the first redundant pad 1121. Simultaneously, since the third pad 1113 is located on the side of the second redundant pad 1122 away from the first pad 1111, that is, between the first pad 1111 and the third pad 1113, when the first pad 1111 and / or the third pad 1113 malfunction, the malfunctioning first pad 1111 and / or third pad 1113 can be repaired by the second redundant pad 1122.

[0066] Since this embodiment uses two redundant pads 112, it can repair the first pad 1111, the second pad 1112 and the third pad 1113, thereby reducing the space occupied by the redundant pads 112, thereby increasing the pixel density of the display device 100 and improving the display effect of the display device 100.

[0067] Optionally, since the third sub-pixel 123 is more prone to damage than the first sub-pixel 121 and the second sub-pixel 122, the second redundant pad 1122 can be preset as another third pad 1113. Thus, when one of the third pads 1113 is damaged, the corresponding third sub-pixel 123 can be driven to emit light of the corresponding color directly through the other third pad 1113. This reduces the difficulty of repairing the third pad 1113 by the second redundant pad 1122, makes it easier for the second redundant pad 1122 to repair the third pad 1113, improves the efficiency of repair, and facilitates the repair operation for the operator.

[0068] In some embodiments, such as Figure 11 and Figure 12 As shown, the pad group 11 includes two redundant pads 112, namely a first redundant pad 1121 and a second redundant pad 1122. The first redundant pad 1121 and the second redundant pad 1122 are respectively disposed on both sides of the third pad 1113. The first pad 1111 is disposed on the side of the first redundant pad 1121 away from the third pad 1113, and the second pad 1112 is disposed on the side of the second redundant pad 1122 away from the third pad 1113.

[0069] Thus, since the first redundant pad 1121 and the second redundant pad 1122 are respectively arranged on two sides of the third pad 1113, the first pad 1111 is arranged on a side of the first redundant pad 1121 away from the third pad 1113, the second pad 1112 is arranged on a side of the second redundant pad 1122 away from the third pad 1113, i.e., the first redundant pad 1121 is arranged between the first pad 1111 and the third pad 1113, and the second redundant pad 1122 is arranged between the second pad 1112 and the third pad 1113, so that when the first pad 1111 is abnormal, the abnormal first pad 1111 can be repaired through the first redundant pad 1121, when the second pad 1112 is abnormal, the abnormal second pad 1112 can be repaired through the second redundant pad 1122, and when the third pad 1113 is abnormal, the abnormal third pad 1113 can be repaired through the first redundant pad 1121 and the second redundant pad 1122.

[0070] Thus, it can be understood that since the third sub-pixel 123 is more likely to be damaged than the first sub-pixel 121 and the second sub-pixel 122, and the first pad 1111 is connected to the first sub-pixel 121, the second pad 1112 is connected to the second sub-pixel 122, and the third pad 1113 is connected to the third sub-pixel 123, i.e., the third pad 1113 is more likely to be damaged than the first pad 1111 and the second pad 1112, the third pad 1113 that is more likely to be damaged can be repaired through the first redundant pad 1121 and the second redundant pad 1122, so that more space can not be occupied, the pixel density of the display device 100 can be improved, and the display effect of the display device 100 can be improved.

[0071] Alternatively, considering the difference between the third sub-pixel 123 and the first sub-pixel 121 and the second sub-pixel 122, the third sub-pixel 123 can adopt the technology of the second sub-pixel 122 combined with quantum dots, so as to further improve the display effect of the display device 100.

[0072] In some embodiments, as Figure 13 and Figure 14As shown, the first pads 1111, the second pads 1112 and the third pads 1113 are all two, and the pad group 11 includes three redundant pads 112, which are a first redundant pad 1121, a second redundant pad 1122 and a third redundant pad 1123; the two first pads 1111, the two second pads 1112 and the two third pads 1113 are respectively arranged on both sides of the first redundant pad 1121, and the first pad 1111 on either side of the first redundant pad 1121 is arranged between the second pad 1112 and the third pad 1113, and the second pad 1112 is located on the side of the third pad 1113 away from the first redundant pad 1121; the second redundant pad 1122 is arranged between the first pad 1111 and the second pad 1112 on one side of the first redundant pad 1121, and the third redundant pad 1123 is arranged between the first pad 1111 and the second pad 1112 on the other side of the first redundant pad 1121.

[0073] Specifically, the first redundant pad 1121 is arranged between the two third pads 1113, the second redundant pad 1122 is arranged between the one first pad 1111 and the one second pad 1112, and the third redundant pad 1123 is arranged between the other first pad 1111 and the other second pad 1112.

[0074] Further, if any one of the third pads 1113 is abnormal, the abnormal third pad 1113 can be repaired through the first redundant pad 1121, and if the first pad 1111 or the second pad 1112 is abnormal, the abnormal first pad 1111 or the abnormal second pad 1112 can be repaired through the second redundant pad 1122 or the third redundant pad 1123.

[0075] Since there are at least 6 main pads 111 and at least 3 redundant pads 112 in one pad group 11, the space occupied by the redundant pads 112 can be greatly reduced, thereby further improving the pixel density of the display device 100 and further improving the display effect of the display device 100.

[0076] In some embodiments, as shown in Figure 2 and Figure 4 As shown, along the direction of the redundant pad 112 towards the first pad 1111, the size of the redundant pad 112 is greater than the size of the first pad 1111, the size of the redundant pad 112 is greater than the size of the second pad 1112, and the size of the redundant pad 112 is greater than the size of the third pad 1113.

[0077] In this way, the redundant pad 112 can be used to repair the first pad 1111, the second pad 1112 and the third pad 1113 synchronously, so that the repair efficiency of the redundant pad 112 on the first pad 1111, the second pad 1112 and the third pad 1113 can be improved. Further, since the redundant pad 112 can repair two main pads 111 synchronously at the same position, the space occupied by the redundant pad 112 can be reduced, so that the display effect of the display device 100 can be improved.

[0078] In some embodiments, as shown in Figure 1 and Figure 3 The plurality of pad groups 11 are arranged in rows along a first direction and arranged in columns along a second direction intersecting the first direction.

[0079] In this way, the pixel density of the display device 100 can be improved by arranging the plurality of pad groups 11 in multiple rows and multiple columns, and the display effect of the display device 100 can be improved.

[0080] Based on the same application concept, the embodiments of the present application also provide a pixel arrangement structure 2.

[0081] It can be understood that when the sub-pixel 12 is abnormal, the corresponding abnormal sub-pixel 12 can be repaired directly by the redundant sub-pixel 211. Since the number of redundant sub-pixels 211 is less than the number of sub-pixels 12, the number of redundant sub-pixels 211 can be reduced during the process of repairing the abnormal sub-pixel 12 by the redundant sub-pixel 211, and the space occupied by the redundant sub-pixel 211 can be reduced, and the space of the display panel 10 and the display device 100 occupied by the redundant sub-pixel 211 can be reduced, the pixel density of the display device 100 can be improved, and the display effect of the display device 100 can be improved.
