[0061] Micro-LED and Mini LED display devices have more than 100,000 or even millions of pixels. Even if the transfer yield reaches 99.9%, there are still hundreds or even thousands of defective LEDs. When there are defective LEDs, they need to be repaired to ensure that the display device has a qualified display effect.

[0062] Currently, the method used to repair defective LEDs is to locate the defective LEDs, peel the defective LEDs off the pads of the display device, and replace them with normal LEDs.

[0063] However, the above repair method requires the steps of removing and installing LEDs. When the number of defective LEDs is large, each defective LED needs to be repaired separately, so the repair time of each LED is added, resulting in a cumbersome and inefficient repair method for the display device.

[0064] In the display device provided by the present application, an in-situ light-emitting unit and a redundant position light-emitting unit corresponding to the in-situ light-emitting unit are arranged on the substrate. When the in-situ light-emitting unit is an abnormal light-emitting unit, a corresponding redundant position light-emitting unit can be arranged to emit light to replace the abnormal light-emitting unit, so that when the in-situ light-emitting unit is damaged to become an abnormal light-emitting unit, there is no need to remove the abnormal light-emitting unit from the substrate, and there is no need to reinstall the normal light-emitting unit to replace the abnormal light-emitting unit, thereby simplifying the repair process of the display device and improving the repair efficiency. The light-shielding layer can shield the redundant position light-emitting unit corresponding to the normal light-emitting unit, so as to prevent the normal light-emitting unit and the corresponding redundant position light-emitting unit from interfering with each other, so that the display device of the present application has a good display effect.

[0065] It should be understood that the Micro-LED in the embodiments of the present application is a micro light emitting diode display, the Mini LED is a micro light emitting diode display, and the LED is a light emitting diode, which will not be repeated in the following content.

[0066] The display device and the method for repairing the display device provided by the present application are described in detail below with reference to specific embodiments.

[0067] The present application embodiment provides a display device, referring to Figure 1 - Figure 4, the display device includes a substrate 100, a light-emitting layer 200 and a light-shielding layer 300. The display device can be applied to electronic devices, and the electronic devices can specifically be mobile phones, tablet computers, laptop computers, PDAs, vehicle-mounted electronic devices, wearable devices, ultramobile personal computers (UMPCs), netbooks or personal digital assistants (PDAs) and other mobile devices, and can also be personal computers (PCs), televisions (TVs), ATMs or self-service machines and other non-mobile devices. Therefore, the embodiment of the present application can also provide an electronic device, which includes the display device described above.

[0068] Among them, the substrate 100 is the basic component of the display device of the present application. The substrate 100 can provide an installation base for at least part of other components of the display device of the present application. The substrate 100 can be a multi-layer stacked structure or a single-layer structure, which is not limited by the present application.

[0069] The light-emitting layer 200 is disposed on the substrate 100, and the light-emitting layer 200 is electrically connected to the substrate 100, so that the substrate 100 can supply power to the light-emitting layer 200. The light-emitting layer 200 specifically includes an in-situ light-emitting portion 211 and a redundant light-emitting portion 212. The in-situ light-emitting portion 211 and the redundant light-emitting portion 212 are both disposed on the substrate 100, and the in-situ light-emitting portion 211 and the redundant light-emitting portion 212 are both electrically connected to the substrate 100. The in-situ light-emitting portion 211 and the redundant light-emitting portion 212 can emit light after being powered on. The in-situ light-emitting portion 211 and the redundant light-emitting portion 212 can specifically be LED chips, that is, light-emitting diode chips.

[0070] It should be understood that in a Micro-LED display device and a Mini LED display device, the number of LED chips may be tens of thousands. Therefore, when the display device of the present application is a Micro-LED display device or a Mini LED display device, the number of the original luminous unit 211 and the redundant luminous unit 212 is also multiple, and the number of the original luminous unit 211 and the redundant luminous unit 212 can be set to be the same or different. When the number of the original luminous unit 211 and the redundant luminous unit 212 is the same, each original luminous unit 211 and each redundant luminous unit 212 are arranged in a one-to-one correspondence. Specifically, an original luminous unit 211 and a corresponding redundant luminous unit 212 can be arranged adjacent to each other and distributed along a preset direction. An original luminous unit 211 and a redundant luminous unit 212 can form a luminous unit group 210, and multiple luminous unit groups 210 can be distributed in an array. When the number of the original luminous part 211 and the redundant luminous part 212 is different, such as the number of the redundant luminous part 212 is greater than the original luminous part 211, at least part of the original luminous part 211 has at least two corresponding redundant luminous parts 212, and accordingly, at least part of the luminous part group 210 may include one original luminous part 211 and at least two redundant luminous parts 212. In addition, it should be understood that the original luminous part 211 of the present application may specifically include a red original sub-luminous part, a green original sub-luminous part and a blue original sub-luminous part, which may correspond to the red, green and blue pixels in the field of display devices, and accordingly, the redundant luminous part 212 may specifically include a red redundant sub-luminous part, a green redundant sub-luminous part and a blue redundant sub-luminous part, so that the original luminous part 211 and the redundant luminous part 212 are fully arranged one by one. It can be understood that the luminous color of the original luminous part 211 is the same as the luminous color of the corresponding redundant luminous part 212.

[0071] The multiple in-situ light-emitting units 211 of the present application include multiple normal light-emitting units 211a and at least one abnormal light-emitting unit 211b, wherein the normal light-emitting unit 211a refers to the in-situ light-emitting unit 211 that can emit light normally and has normal indicators such as the color and brightness of the light, and the abnormal light-emitting unit 211b refers to the in-situ light-emitting unit 211 whose indicators such as the color and brightness of the light do not meet the standards. Each normal light-emitting unit 211a and each abnormal light-emitting unit 211b has a corresponding redundant position light-emitting unit 212.

[0072] The light shielding layer 300 is arranged to cover the light emitting layer 200. Specifically, the light shielding layer 300 covers the side of the light emitting layer 200 away from the substrate 100. Among them, the light emitting side of the original luminous part 211 is not covered by the light shielding layer 300, so that all the original luminous parts 211 are exposed, so that the light emitted by all the original luminous parts 211 can be illuminated. The redundant position luminous part 212 corresponding to the abnormal luminous part 211b is also not covered by the light shielding layer 300, so that the redundant position luminous part 212 corresponding to the abnormal luminous part 211b is exposed, so that it can emit light normally, so that the redundant position luminous part 212 can replace the abnormal luminous part 211b to emit light. The shading layer 300 covers the light-emitting sides of at least a portion of the redundant light-emitting units 212. The light emitted by the redundant light-emitting units 212 corresponding to the normal light-emitting units 211a covered by the shading layer 300 cannot pass through the shading layer 300. In this way, the redundant light-emitting units 212 will not interfere with the light emission of the normal light-emitting units 211a, so that each pixel point of the display device of the present application can emit light normally.

[0073] Specifically, the light shielding layer 300 is provided with a first opening 310 and a second opening 320. The first opening 310 is arranged corresponding to the normal light-emitting portion 211a. The normal light-emitting portion 211a can be exposed on the substrate 100 through the first opening 310, so that all the light emitted by the normal light-emitting portion 211a can be illuminated. The redundant position light-emitting portion 212 corresponding to the abnormal light-emitting portion 211b corresponds to the second opening 320, so that the redundant position light-emitting portion 212 can be exposed on the substrate 100, so that the redundant position light-emitting portion 212 replaces the abnormal light-emitting portion 211b to emit light. Therefore, in the present application, it is not necessary to remove the abnormal light-emitting portion 211b. By exposing the redundant position light-emitting portion 212 corresponding to the abnormal light-emitting portion 211b, the redundant position light-emitting portion 212 already arranged on the substrate 100 can replace the abnormal light-emitting portion 211b. In this way, there is no need to reinstall the light-emitting component that replaces the abnormal light-emitting portion 211b on the substrate 100, thereby making the display device of the present application highly efficient in repair. In addition, the light-shielding layer 300 of the present application is also provided with a third opening 330, and the third opening 330 is arranged corresponding to the abnormal light-emitting portion 212b, so that the abnormal light-emitting portion 212b is exposed and arranged on the substrate 100. In this way, the corresponding redundant position light-emitting portion 212 can be determined according to the position of the abnormal light-emitting portion 212b, so as to facilitate the opening of a second opening 320 on the light-shielding layer 300.

[0074] In some embodiments, referring to FIG. 2 , the substrate 100 of the present application may specifically include a base layer 110, a driving circuit layer 120, and a connecting layer 130, wherein the base layer 110 is a basic component of the substrate 100, and the base layer 110 may provide a mounting base for at least part of other components of the substrate 100. When the display device of the present application is a rigid display device, the base layer 110 may specifically adopt a glass substrate so that the substrate 100 has good structural strength. When the display device of the present application is a flexible display device, the base layer 110 may specifically be prepared using a polyimide material. The present application does not limit the specific material of the base layer 110.

[0075] The driving circuit layer 120 can be stacked on the base layer 110. The driving circuit layer 120 can specifically be provided with a TFT driving circuit, i.e., a thin film transistor driving circuit. Of course, the driving circuit layer 120 can also be other circuit structures, and this application does not limit this. The connecting layer 130 is stacked on the side of the driving circuit layer 120 away from the base layer 110, and the connecting layer 130 is electrically connected to the driving circuit layer 120. The light-emitting layer 200 is stacked on the side of the connecting layer 130 away from the driving circuit layer 120, and the light-emitting layer 200 is also electrically connected to the connecting layer 130. Therefore, the driving circuit layer 120 can be electrically connected to the light-emitting layer 200 through the connecting layer 130. In this way, the driving circuit layer 120 can drive the original light-emitting portion 211 and the redundant position light-emitting portion 212 to emit light. The connection layer 130 can be specifically configured as a solder pad, and the pins of the original position light emitting unit 211 and the redundant position light emitting unit 212 can be welded on the connection layer 130, so that the original position light emitting unit 211 and the redundant position light emitting unit 212 can be fixed on the connection layer 130 and electrically connected to the connection layer 130. Of course, the connection layer 130 can also be configured as a layered structure with conductive through holes, and the driving circuit layer 120 can be electrically connected to the original position light emitting unit 211 and the redundant position light emitting unit 212 through the conductive through holes. The present application does not limit the specific structure of the connection layer 130.

[0076] In some embodiments, reference Figure 5, an original position light-emitting unit 211 and a corresponding redundant position light-emitting unit 212 can jointly constitute a light-emitting unit group 210. Since the number of original position light-emitting units 211 and redundant position light-emitting units 212 are both multiple, the number of light-emitting unit groups 210 is also multiple. The connection layer 130 of the present application may specifically include multiple connection parts 131, and the multiple connection parts 131 are all electrically connected to the driving circuit layer 120. The multiple connection parts 131 are also connected to multiple light-emitting unit groups 210 in a one-to-one correspondence, that is, one connection part 131 can be electrically connected to the original position light-emitting unit 211 and the redundant position light-emitting unit 212 in a light-emitting unit group 210, so that the multiple connection parts 131 can respectively drive the multiple light-emitting unit groups 210 to emit light. Multiple connection parts 131 are independently arranged, and damage to any one connection part 131 will not affect the normal use of other connection parts 131, so that the light-emitting unit groups 210 connected to other connection parts 131 can also emit light normally without being affected, preventing the situation where all light-emitting unit groups 210 are affected due to damage to part of the connection layer 130.

[0077] In some embodiments, reference Figure 5 , the driving circuit layer 120 of the present application may include multiple driving circuits 121, and the multiple driving circuits 121 may be connected to the multiple light-emitting unit groups 210 in a one-to-one correspondence, so that one driving circuit 121 can drive one light-emitting unit group 210 to emit light independently. Specifically, the multiple driving circuits 121 are also connected to the multiple connecting parts 131 in a one-to-one correspondence, so that the multiple driving circuits 121 are respectively connected to the multiple light-emitting unit groups 210 in a one-to-one correspondence through the multiple connecting parts 131, so that one driving circuit 121 corresponds to one connecting part 131 and one light-emitting unit group 210. The multiple driving circuits 121 are independently arranged, and any damaged driving circuit 121 will not affect the normal use of other driving circuits 121. Prevent the situation where all light-emitting unit groups 210 are affected due to damage to some driving circuits 121.

[0078] To sum up, in the display device of the present application, by setting up multiple independent connecting parts 131 and driving circuits 121, when any driving circuit 121 and / or connecting part 131 is damaged, only the light-emitting part group 210 connected to the damaged driving circuit 121 and / or connecting part 131 among the multiple light-emitting part groups 210 is affected, while the other light-emitting part groups 210 can be unaffected and emit light normally, thereby making the reliability and stability of the display device of the present application better.

[0079] In some embodiments, reference Figure 4a and Figure 4b, the connection part 131 of the present application may specifically include a first sub-connection part 131a and a second sub-connection part 131b, and the number of the first sub-connection parts 131a is consistent with the number of the second sub-connection parts 131b. Since the number of the connection part 131 is multiple, the number of the first sub-connection parts 131a and the second sub-connection parts 131b are both multiple, and the multiple first sub-connection parts 131a can be connected to the multiple in-situ light-emitting parts 211 in a one-to-one correspondence, and the multiple second sub-connection parts 131b can be connected to the multiple redundant position light-emitting parts 212 in a one-to-one correspondence. Therefore, the multiple in-situ light-emitting parts 211 are connected to the driving circuit 121 through the multiple first sub-connection parts 131a in a one-to-one correspondence, and the multiple redundant position light-emitting parts 212 are connected to the driving circuit 121 through the multiple second sub-connection parts 131b in a one-to-one correspondence.

[0080] When the first sub-connection part 131a in any connection part 131 is damaged, the original luminous part 211 connected to it can be disconnected, while the redundant luminous part 212 in the luminous part group 210 is connected to the second sub-connection part 131b, and the second sub-connection part 131b is not damaged. Therefore, the redundant luminous part 212 can emit light normally without being affected. This can prevent a certain connection part 131 from being partially damaged, causing the original luminous part 211 and the redundant luminous part 212 connected to the connection part 131 to be damaged. When the second sub-connection part 131b in any connection part 131 is damaged, the redundant position light-emitting part 212 connected to it can be disconnected, and the original position light-emitting part 211 in the light-emitting part group 210 is connected to the first sub-connection part 131a, and the first sub-connection part 131a is not damaged. Therefore, the original position light-emitting part 211 can emit light normally without being affected. This can also prevent a certain connection part 131 from being partially damaged, causing the original position light-emitting part 211 and the redundant position light-emitting part 212 connected to the connection part 131 to be damaged.

[0081] In some embodiments, reference Figure 4a and Figure 4b The driving circuit 121 of the present application may specifically include a first sub-driving circuit 121a and a second sub-driving circuit 121b, and the number of the first sub-driving circuits 121a is the same as the number of the second sub-driving circuits 121b. Since the number of the driving circuit 121 is multiple, the number of the first sub-driving circuit 121a and the second sub-driving circuit 121b are both multiple, and the multiple first sub-driving circuits 121a can be connected to the multiple original-position light-emitting units 211 in a one-to-one correspondence through the connecting portion 131, and the multiple second sub-driving circuits 121b can be connected to the multiple redundant-position light-emitting units 212 in a one-to-one correspondence through the connecting portion 131.

[0082] When the first sub-driving circuit 121a in any driving circuit 121 is damaged, the original luminous unit 211 connected to it can be disconnected, while the redundant luminous unit 212 in the luminous unit group 210 is connected to the second sub-driving circuit 121b, and the second sub-driving circuit 121b is not damaged. Therefore, the redundant luminous unit 212 can emit light normally without being affected. This can prevent a certain driving circuit 121 from being partially damaged, causing both the original luminous unit 211 and the redundant luminous unit 212 connected to the driving circuit 121 to be damaged. When the second sub-driving circuit 121b in any driving circuit 121 is damaged, the redundant position light-emitting unit 212 connected to it can be disconnected, while the original position light-emitting unit 211 in the light-emitting unit group 210 is connected to the first sub-driving circuit 121a, and the first sub-driving circuit 121a is not damaged. Therefore, the original position light-emitting unit 211 can emit light normally without being affected. This can prevent a certain driving circuit 121 from being partially damaged, causing the original position light-emitting unit 211 and the redundant position light-emitting unit 212 connected to the driving circuit 121 to be damaged.

[0083] In some embodiments, it should be understood that since the normal light-emitting portion 211a can emit light normally, the corresponding redundant light-emitting portion 212 is covered by the light-shielding layer 300. In this way, although the light emitted by the redundant light-emitting portion 212 cannot penetrate the light-shielding layer 300 and affect the original light-emitting portion 211, the redundant light-emitting portion 212 is still connected to the driving circuit 121 through the connecting portion 131, so that the redundant light-emitting portion 212 is powered on and generates energy consumption, resulting in high energy consumption of the display device of the present application during normal operation. The abnormal light-emitting portion 211b may include an abnormal light-emitting portion 211b that can emit light, but the light brightness and light color do not meet the standards. Although this type of abnormal light-emitting portion 211b cannot emit light normally, it is connected to the driving circuit 121 through the connecting portion 131, so the abnormal light-emitting portion 211b is still in a powered-on state and generates additional energy consumption, which will also cause the display device of the present application to have high energy consumption.

[0084] In order to reduce the energy consumption of the display device of the present application, the redundant bit light-emitting unit 212 corresponding to the normal light-emitting unit 211a can be disconnected from the driving circuit layer 120, and the abnormal light-emitting unit 211b can be disconnected from the driving circuit layer 120. In this way, the redundant bit light-emitting unit 212 corresponding to the normal light-emitting unit 211a is no longer powered on, and the abnormal light-emitting unit 211b is no longer powered on, thereby reducing the energy consumption of the display device of the present application.

[0085] In the present application, the first sub-connection portion 131a corresponding to the abnormal light-emitting portion 211b can be disconnected from the abnormal light-emitting portion 211b, so that the abnormal light-emitting portion 211b can not emit light and no power is supplied, so that the abnormal light-emitting portion 211b can not generate energy consumption. The redundant position light-emitting portion 212 corresponding to the normal light-emitting portion 211a has a corresponding second sub-connection portion 131b, so that the above-mentioned redundant position light-emitting portion 212 is disconnected from the corresponding second sub-connection portion 131b, so that the above-mentioned redundant position light-emitting portion 212 can not emit light and no power is supplied, so that the above-mentioned redundant position light-emitting portion 212 can not generate energy consumption, which can effectively reduce the energy consumption of the display device of the present application. Specifically, the pin of the abnormal light-emitting part 211b can be separated from the corresponding first sub-connection part 131a, so that the abnormal light-emitting part 211b is disconnected from the corresponding first sub-connection part 131a; the pin of the redundant light-emitting part 212 corresponding to the normal light-emitting part 211a can be separated from the corresponding second sub-connection part 131b, so that the redundant light-emitting part 212 is disconnected from the corresponding second sub-connection part 131b.

[0086] In addition, in some embodiments, the first sub-driving circuit 121a corresponding to the abnormal light-emitting portion 211b can be disconnected from the abnormal light-emitting portion 211b, so that the abnormal light-emitting portion 211b can not emit light and not be powered, so that the abnormal light-emitting portion 211b can not generate energy consumption. The redundant position light-emitting portion 212 corresponding to the normal light-emitting portion 211a has a corresponding second sub-driving circuit 121b, so that the above-mentioned redundant position light-emitting portion 212 is disconnected from the corresponding second sub-driving circuit 121b, so that the above-mentioned redundant position light-emitting portion 212 can not emit light and not be powered, so that the above-mentioned redundant position light-emitting portion 212 can not generate energy consumption, which can effectively reduce the energy consumption of the display device of the present application.

[0087] In addition, in the embodiment of the present application, the first sub-connection part 131a and the first sub-driving circuit 121b corresponding to the abnormal light-emitting part 211b can be disconnected from the abnormal light-emitting part 211b, and the redundant bit light-emitting part 212 corresponding to the normal light-emitting part 211a can be disconnected from the corresponding second sub-connection part 131b and the second sub-driving circuit 121b, thereby achieving the purpose of reducing the energy consumption of the display device of the present application.

[0088] Specifically, in the present application, in order to disconnect the abnormal light-emitting part 211b from the corresponding first sub-driving circuit 121a, the first sub-driving circuit 121a corresponding to the abnormal light-emitting part 211b can be disconnected from the first sub-connecting part 131a corresponding to the abnormal light-emitting part 211b, so that the abnormal light-emitting part 211b can be disconnected from the corresponding first sub-driving circuit 121a.

[0089] In order to disconnect the redundant light-emitting unit 212 corresponding to the normal light-emitting unit 211a from the corresponding second sub-driving circuit 121b, the second sub-driving circuit 121b corresponding to the redundant light-emitting unit 212 can be disconnected from the second sub-connecting unit 131b corresponding to the redundant light-emitting unit 212, so that the redundant light-emitting unit 212 can be disconnected from the corresponding second sub-driving circuit 121b.

[0090] Specifically, the connection line between the first sub driving circuit 121a and the first sub connecting portion 131a may be cut off, and the connection line between the second sub driving circuit 121b and the second connecting portion 131b may be cut off.

[0091] In some embodiments, reference Figure 4a and Figure 4b In order to facilitate the abnormal light-emitting portion 211b to be disconnected from the corresponding first sub-driving circuit 121a, and to facilitate the redundant light-emitting portion 212 corresponding to the normal light-emitting portion 211a to be disconnected from the corresponding second sub-driving circuit 121b, an auxiliary opening 340 may be provided on the light-shielding layer 300 of the present application, and the auxiliary opening 340 may penetrate the light-shielding layer 300 to the connecting layer 130, so that at least part of the connecting layer 130 may be exposed. Specifically, the part of the connecting layer 130 exposed by the auxiliary opening 340 corresponds to the abnormal light-emitting portion 211b, and corresponds to the redundant light-emitting portion 212 corresponding to the normal light-emitting portion 211a, so that the abnormal light-emitting portion 211b and the redundant light-emitting portion 212 corresponding to the normal light-emitting portion 211a can be disconnected from the corresponding driving circuit layer 120.

[0092] In some embodiments, it should be understood that when the original luminous part 211 and the redundant luminous part 212 of the present application are arranged one by one, if the original luminous part 211 and the redundant luminous part 212 in the luminous part group 210 are abnormal, it will cause a certain luminous part group 210 of the display device of the present application to be completely damaged and cannot be repaired. In order to make the display device of the present application more reliable, the number of redundant luminous parts 212 in the luminous layer 200 can be set to be greater than the number of original luminous parts 211, so that any original luminous part 211 has at least two corresponding redundant luminous parts 212, so that when the original luminous part 211 is an abnormal luminous part 211b, and one of the corresponding redundant luminous parts 212 is also damaged abnormally, the other corresponding redundant luminous parts 212 can replace the abnormal luminous part 211b and the damaged redundant luminous part 212, thereby avoiding the complete damage of a certain luminous part group 210 of the display device. Of course, the more the number of redundant luminous parts 212 corresponding to the original luminous part 211 is set, the more reliable the display device of the present application can be. Specifically, the multiple redundant position light-emitting units 212 corresponding to the original position light-emitting unit 211 can be arranged on different sides of the original position light-emitting unit 211 or on the same side of the original position light-emitting unit 211. The present application does not limit the arrangement of the multiple redundant position light-emitting units 212 on one side of the original position light-emitting unit 211.

[0093] The embodiment of the present application also proposes a method for repairing a display device, which can be used to repair a display device to be repaired, and the display device finally repaired is the display device described above.

[0094] Therefore, reference Figure 6 , the embodiment of the present application also proposes a display device to be repaired, wherein the display device to be repaired includes a substrate 100 and a light-emitting layer 200, wherein the light-emitting layer 200 can be arranged on the substrate 100, and the light-emitting side of the light-emitting layer 200 faces away from the substrate 100, so that the display device to be repaired has an upper light-emitting structure. The light-emitting layer 200 includes a plurality of in-situ light-emitting parts 211 and a plurality of redundant light-emitting parts 212, the in-situ light-emitting parts 211 and the redundant light-emitting parts 212 are arranged correspondingly, and the plurality of in-situ light-emitting parts 211 include a plurality of normal light-emitting parts 211a and at least one abnormal light-emitting part 211b. Specifically, the number of the in-situ light-emitting parts 211 and the redundant light-emitting parts 212 can be set to be the same, and the plurality of in-situ light-emitting parts 211 and the plurality of redundant light-emitting parts 212 are arranged one by one. Of course, the number of redundant light-emitting parts 212 can also be set to be greater than the number of the in-situ light-emitting parts 211, so that at least part of the in-situ light-emitting parts 211 have at least two corresponding redundant light-emitting parts 212. The display device repair method of the present application can solve the problem that the abnormal light-emitting portion 211b in the display device to be repaired emits abnormal light, resulting in poor display effect of the display device to be repaired.

[0095] refer to Figure 7 The display device repair method of the present application specifically includes the following steps:

[0096] S100, forming a light shielding layer, wherein the light shielding layer covers the side of the light emitting layer away from the substrate. Figure 2a Specifically, the light shielding layer 300 can be made of BM (Black matrix) glue, which is a photoresist material commonly used in semiconductor manufacturing, and its main components are styrene-butadiene copolymer (SBR) and methyl acrylate-methyl methacrylate copolymer (PMMA). By using BM glue as the light shielding layer 300, the light emitting layer 200 can be effectively shielded, so that the light emitted by the light emitting layer 200 can be shielded by the light shielding layer 300.

[0097] S200, forming a repair opening on the light shielding layer, wherein the repair opening corresponds to exposing a plurality of in-situ light emitting portions. Figure 2b Specifically, the repair opening on the light shielding layer 300 is opposite to the original luminous part 211, and the inner diameter of the repair opening is larger than the outer diameter of the light-emitting side of the original luminous part 211, so that the light-emitting side of the original luminous part 211 is located in the repair opening, so that the light emitted by the original luminous part 211 can be illuminated through the repair opening, so that the original luminous part 211 can emit light normally. The repair opening specifically includes a first opening 310 and a third opening 330, wherein the third opening 330 corresponds to exposing the normal luminous part 211a, and the first opening 310 corresponds to exposing the abnormal luminous part 211b.

[0098] S300, determining the first position of the abnormal light-emitting portion in the in-situ light-emitting portion. Specifically, the position of the normal light-emitting portion 211a in the in-situ light-emitting portion 211 is the third position 160, and the third position 160 of the normal light-emitting portion 211a and the first position 140 of the abnormal light-emitting portion 211b are randomly distributed on the substrate 100, so the first position 140 and the third position 160 need to be determined.

[0099] S400, determine the second position of the redundant position light emitting unit corresponding to the abnormal light emitting unit. Since the redundant position light emitting unit 212 is arranged corresponding to the original position light emitting unit 211, when the first position 140 of the abnormal light emitting unit 211b is determined, the second position 150 of the redundant position light emitting unit 212 corresponding to the abnormal light emitting unit 211b can be determined.

[0100] S500, forming a second opening on the light shielding layer, the second opening correspondingly exposing the redundant light emitting portion corresponding to the abnormal light emitting portion. Figure 3 and Figure 4aSpecifically, the second opening 320 on the light-shielding layer 300 is opposite to the redundant light-emitting portion 212 corresponding to the abnormal light-emitting portion 211b, and the inner diameter of the second opening 320 is larger than the outer diameter of the light-emitting side of the redundant light-emitting portion 212, so that the light-emitting side of the redundant light-emitting portion 212 is located in the second opening 320, so that the light emitted by the redundant light-emitting portion 212 can be illuminated through the second opening 320.

[0101] In addition, the redundant light-emitting portion 212 corresponding to the normal light-emitting portion 211a is still covered and shielded by the shading layer 300, so that the light emitted by the redundant light-emitting portion 212 corresponding to the normal light-emitting portion 211a is blocked by the shading layer 300, so that the redundant light-emitting portion 212 will not affect the normal light-emitting portion 211a.

[0102] In some embodiments, it should be understood that the original luminous part 211 and the redundant luminous part 212 in the present application are arranged at intervals on the substrate 100, so there are gaps between adjacent original luminous parts 211, adjacent redundant luminous parts 212, and adjacent original luminous parts 211 and redundant luminous parts 212. The light shielding layer 300 of the present application can be stacked on the side of the substrate 100 carrying the light-emitting layer 200 through a packaging process, so that the light shielding layer 300 can not only cover the original luminous part 211 and the redundant luminous part 212, but also fill the gaps between the adjacent original luminous part 211, the adjacent redundant luminous part 212, and the adjacent original luminous part 211 and the redundant luminous part 212, so as to fully cover the original luminous part 211 and the redundant luminous part 212. After the repair opening and the second opening 320 are formed on the light shielding layer 300, the light shielding layer 300 can also fully cover and block the redundant luminous part 212 corresponding to the normal luminous part 211a.

[0103] In some embodiments, the formation of the repair opening and the second opening 320 on the light shielding layer 300 in the present application can be specifically achieved by exposure and development. Specifically, before the light shielding layer 300 is encapsulated on the substrate 100, the position of the in-situ light emitting portion 211 on the substrate 100 is determined, and the portion of the light shielding layer 300 corresponding to the in-situ light emitting portion 211 is exposed by an exposure machine or a photolithography machine, and then the exposed light shielding layer 300 is developed, and the chemical substances in the developer can react with the exposed portion of the light shielding layer 300, dissolving the portion of the light shielding layer 300, thereby forming a repair opening on the light shielding layer 300, so that the in-situ light emitting portion 211 can be exposed. In addition, in the present application, the second opening 320 on the light shielding layer 300 can also be opened on the light shielding layer 300 by exposure and development.

[0104] It should be understood that the exposure and development process can be completed by dedicated semiconductor equipment, which can greatly improve the efficiency of forming the repair opening and the second opening 320 on the light shielding layer 300. In addition, it should be noted that after the repair opening and the second opening 320 are formed on the light shielding layer 300 by exposure and development, the light shielding layer 300 can surround the original luminous part 211 and the redundant luminous part 212, and because the light shielding layer 300 covers the original luminous part 211 and the redundant luminous part 212, the height of the light shielding layer 300 is higher than the light emitting side of the original luminous part 211 and the redundant luminous part 212, so that the light shielding layer 300 can also gather the light emitted by the original luminous part 211 and the redundant luminous part 212, making the light more concentrated, and at the same time, it can also prevent the adjacent original luminous part 211, the adjacent redundant luminous part 212, and the adjacent original luminous part 211 and the redundant luminous part 212 from interfering with each other.

[0105] In some embodiments, the determination of the normal light-emitting portion 211a and the abnormal light-emitting portion 211b in the in-situ light-emitting portion 211 in the present application can be specifically determined by an AOI inspection device (automated optical inspection device). Specifically, after the repair opening formed on the light-shielding layer 300 by the exposure and development process exposes all the in-situ light-emitting portions 211, the first position 140 of the abnormal light-emitting portion 211b is obtained by the AOI inspection device. Since the abnormal light-emitting portion 211b and the corresponding redundant light-emitting portion 212 are correspondingly arranged, after the position of the abnormal light-emitting portion 211b is determined, the second position 150 of the redundant light-emitting portion 212 corresponding to the abnormal light-emitting portion 211b can be determined accordingly. When the AOI inspection device inspects the display device to be repaired, the AOI inspection device automatically scans the display device through a high-definition CCD camera, collects images, and compares the collected images with the parameters of the normal light-emitting part 211a and the parameters of the abnormal light-emitting part 211b stored in the database. After image processing, the first position 140 of the abnormal light-emitting part 211b and the second position 150 of the redundant light-emitting part 212 corresponding to the abnormal light-emitting part 211b are detected. In this way, obtaining the first position 140 and the second position 150 through the AOI inspection device can greatly improve efficiency, thereby making the display device repair method of the present application more efficient. Among them, the CCD camera is a charge-coupled device.

[0106] In some embodiments, reference Figure 8 The display device repair method of the present application further includes the following steps:

[0107] S600, determining a third position of the normal light-emitting portion;

[0108] S700, determine the fourth position of the redundant position light emitting unit corresponding to the normal light emitting unit. Since the redundant position light emitting unit 212 is arranged corresponding to the original position light emitting unit 211, when the third position 160 of the normal light emitting unit 211a is determined, the fourth position 170 of the redundant position light emitting unit 212 corresponding to the normal light emitting unit 211a can be determined. In addition, the third position 160 of the normal light emitting unit 211a can also be determined by an AOI inspection device, or after the first position 140 of the abnormal light emitting unit 211b is determined, the third position 160 of the normal light emitting unit 211a is obtained by comparing with the preset arrangement of the original position light emitting unit 211.

[0109] S800, cut off the abnormal light-emitting part and the redundant light-emitting part at the fourth position. After the abnormal light-emitting part 211b at the first position 140 and the redundant light-emitting part 212 at the fourth position 170 are cut off, the abnormal light-emitting part 211b and the redundant light-emitting part 212 are no longer powered, so that the abnormal light-emitting part 211b and the redundant light-emitting part 212 no longer consume energy, thereby reducing the energy consumption of the display device to be repaired after being repaired by the display device repair method of the present application.

[0110] In some embodiments, reference Fig. 9 S800: Cutting off the abnormal light-emitting unit and the redundant light-emitting unit at the fourth position, specifically comprising the following steps:

[0111] S810, forming an auxiliary opening on the light shielding layer, the auxiliary opening correspondingly exposes the first sub-connection part and / or the first sub-driving circuit corresponding to the abnormal light-emitting part, and the second sub-connection part and / or the second sub-driving circuit corresponding to the redundant position light-emitting part at the fourth position. After the first position 140 and the fourth position 170 are obtained by the AOI detection equipment, the part adjacent to the first position 140 and the fourth position 170 on the light shielding layer 300 can be eliminated by an exposure and development process to form an auxiliary opening 340, so that the auxiliary opening 340 can expose the first sub-connection part 131a, the second sub-connection part 131b, the first sub-driving circuit 121a and the second sub-driving circuit 121b that need to be cut off.

[0112] S820, cut off the connection between the first sub-connection part exposed by the auxiliary opening and the first sub-driving circuit, and cut off the connection between the second sub-connection part and the second sub-driving circuit by etching process. Specifically, the wiring of the abnormal light-emitting part 211b at the first position 140 and the wiring of the redundant position light-emitting part 212 at the fourth position 170 can be cut off by laser or chemical etching process, so that the abnormal light-emitting part 211b at the second position 150 and the redundant position light-emitting part 212 at the fourth position 170 can be finely controlled to be disconnected from the substrate 100. In addition, the chemical etching process can efficiently disconnect the abnormal light-emitting part 211b at the first position 140 and the redundant position light-emitting part 212 at the fourth position 170, and the cost of disconnecting the abnormal light-emitting part 211b and the redundant position light-emitting part 212 at the fourth position 170 by laser is relatively low.

[0113] In some embodiments, if the redundant position light emitting unit 212 corresponding to the abnormal light emitting unit 211b in the present application is also abnormal, it may cause the display device to be repaired to be unable to be repaired. Therefore, in order to solve the above problem, the number of redundant position light emitting units 212 in the light emitting layer 200 of the display device to be repaired in the present application is greater than the number of original position light emitting units 211, and any original position light emitting unit 211 has at least two corresponding redundant position light emitting units 212. Therefore, referring to Fig.10 In the display device repair method of the present application, S500: forming a second opening 320 on the light shielding layer 300, the second opening 320 corresponding to the redundant bit light emitting portion 212 corresponding to the abnormal light emitting portion 211b, specifically includes the following steps:

[0114] S510, forming a second opening on the light shielding layer, the second opening correspondingly exposing the redundant light emitting portion corresponding to the abnormal light emitting portion;

[0115] S520, determining the light emitting status of the redundant bit light emitting unit at the second position;

[0116] S530, determining the light emitting status of the redundant bit light emitting unit at the second position;

[0117] S540, when the redundant bit light emitting portion at the second position displays an abnormality, forming another second opening on the light shielding layer, the other second opening correspondingly exposing another redundant bit light emitting portion corresponding to the abnormal light emitting portion;

[0118] S550, determining the light emitting status of another redundant light emitting portion until another redundant light emitting portion corresponding to another second opening emits light normally.

[0119] Therefore, the more redundant bit light-emitting units 212 are arranged corresponding to the original bit light-emitting units 211, the more reliable the display device repair method of the present application is.

[0120] The embodiment of the present application also proposes a display device, which includes a substrate 100, a light-emitting layer 200 and a light-shielding layer 300, wherein the light-emitting layer 200 can be arranged on the substrate 100, and the light-emitting side of the light-emitting layer 200 faces away from the substrate 100, so that the display device has an upper light-emitting structure. The light-emitting layer 200 includes a plurality of in-situ light-emitting parts 211 and a plurality of redundant position light-emitting parts 212, and the in-situ light-emitting parts 211 and the redundant position light-emitting parts 212 are arranged correspondingly. The light-shielding layer 300 is superimposed on the side of the light-emitting layer 200 facing away from the substrate 100, so that the light-shielding layer 300 can block and cover all the multiple redundant position light-emitting parts 212. When all the original luminous units 211 can emit light normally, the display device of the present application can be used normally. If some of the original luminous units 211 fail and cannot emit light normally at a later stage, the shading layer 300 corresponding to the redundant luminous unit 212 corresponding to the abnormal luminous unit 211b can be peeled off to expose the redundant luminous unit 212, so that the redundant luminous unit 212 can replace the abnormal luminous unit 211b.
