[0003] However, Micro-LED light-emitting chips have three colors: red, green, and blue.

[0066] The exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art.

[0067] Embodiment 1

[0068] Refer to Figures 1 to 3 As shown, the present application provides a display module. The display module includes display sub-pixels 10 and a driving board 20. The driving board 20 is provided with a driving layer 220. For example, the driving board 20 includes a substrate 210. The substrate 210 can be a glass plate or a plastic plate. The driving layer 220 is disposed on the substrate 210. The driving layer 220 is used to provide an electrical signal to the display sub-pixels 10. The display sub-pixels 10 are drivingly connected to the driving layer 220 of the driving board 20; the driving layer 220 includes a thin-film driving transistor T, a driving electrode PVDD, and a sub-pixel electrode PVEE. The driving electrode is connected to the sub-pixel electrode and provides a driving voltage to the display sub-pixels 10 to ensure that the display sub-pixels 10 can be lit.

[0069] The display sub-pixels 10 include a first display structure 110 and a second display structure 120, and the first display structure 110 and the second display structure 120 are spaced apart; the first display structure 110 and the second display structure 120 can be separately and independently controlled, or the first display structure 110 and the second display structure 120 can be lit simultaneously.

[0070] The first display structure 110 includes a first red light-emitting layer 111 and a first green light-emitting layer 112, and the first red light-emitting layer 111 and the first green light-emitting layer 112 are stacked in a direction perpendicular to the driving layer 220 of the driving board 20; the first red light-emitting layer 111 can emit red light, and the first green light-emitting layer 112 can emit green light.

[0071] The second display structure 120 includes a second red light-emitting layer 121 and a first blue light-emitting layer 122, and the second red light-emitting layer 121 and the first blue light-emitting layer 122 are stacked in a direction perpendicular to the driving layer 220 of the driving board 20. The second red light-emitting layer 121 can emit red light, and the first blue light-emitting layer 122 can emit blue light. The red light emitted by the first red light-emitting layer 111 and the red light emitted by the second red light-emitting layer 121 have similar wavelengths or are the same. By controlling the voltages applied to the first red light-emitting layer 111 and the first green light-emitting layer 112, the ratio of red light and green light can be controlled, and by controlling the voltages applied to the second red light-emitting layer 121 and the first blue light-emitting layer 122, the ratio of red light and blue light can be controlled. It can be seen from this that in this embodiment, different colors can be formed by different light-emitting ratios of red light, green light, and blue light.

[0072] Since at least one of the first display structure and the second display structure has different color light-emitting layers stacked up and down, that is, one of the display structures has two light-emitting layers. By stacking the two light-emitting layers up and down, it is equivalent to completing the transfer work of two-color light-emitting chips at the same time during the transfer work. Therefore, by separately transferring the first display structure and the second display structure, the transfer times can be effectively reduced and the transfer efficiency can be improved.

[0073] In this embodiment, the first red light-emitting layer 111 and the first green light-emitting layer 112 are stacked together. When the transfer work is carried out, the transfer of the first display structure 110 is completed, which is equivalent to completing the transfer work of two-color light-emitting chips at the same time. Similarly, it can be seen that the second red light-emitting layer 121 and the first blue light-emitting layer 122 are stacked together. When the transfer work of the second display structure 120 is completed, it is also equivalent to completing the transfer work of two-color light-emitting chips. Therefore, by separately transferring the first display structure 110 and the second display structure 120, the transfer times can be effectively reduced and the transfer efficiency can be improved.

[0074] Moreover, through the stacked arrangement of the light-emitting layers in the first display structure 110 and the second display structure 120, the position space occupied by a single light-emitting layer is reduced. Therefore, more display sub-pixels 10 can be arranged in a limited space position, improving the resolution of the display panel.

[0075] Refer to Figure 4As shown, in this embodiment, for the driving method, Sn and Sn+1 are scan lines, providing gate scan signals. Data_n, Data_n+1, Data_n+2, Data_n+3, Data_n+4 and Data_n+5 are data lines, providing data signals respectively. When Sn is at a high potential, the other gate scan signals are low; Data_n provides a data signal for the nth column to drive the first green light-emitting layer 112 of the first display structure 110; Data_n+1 provides a data signal for the n+1th column to drive the first red light-emitting layer 111 of the first display structure 110 to emit light, and at the same time drives the second red light-emitting layer 121 of the second display structure 120 to emit light; It can be seen that in this embodiment, the light-emitting process of the first display structure 110 and the second display structure 120 can be driven and controlled simultaneously through one data line, which can simplify the circuit design. Data_n+2 provides a data signal for the n+2th column to drive the first blue light-emitting layer 122 of the second display structure 120 to light up, so that the first display structure 110 and the second display structure 120 complete the light-emitting display.

[0076] In addition, the luminous efficiency of the general red light-emitting layer is low. In the same display sub-pixel 10, two structures capable of emitting red light, namely the first red light-emitting layer 111 and the second red light-emitting layer 121, are provided to increase the amount of emitted red light, thereby compensating for the low efficiency of the red light-emitting layer.

[0077] Due to the provision of two layers of red light-emitting layers, the red light-emitting efficiency is significantly improved; because, through the controller, the brightness of the two layers of red light-emitting layers are stimulated to 0.75 times the brightness of the blue or green light-emitting layer. At this time, the total brightness of the two layers of red light-emitting layers is 1.5 times the brightness of the blue or green light-emitting layer. At this time, when the red light-emitting efficiency is low, the amount of red light emitted can be increased, thereby improving the overall display effect; and the load of the red light-emitting layer can be reduced, thereby increasing the service life of the red light-emitting layer, thereby increasing the overall service life of the display module.

[0078] Furthermore, due to the stacking arrangement, the overall height of the first display structure 110 and the second display structure 120 is increased. When performing mass transfer, the positions of the first display structure 110 and the second display structure 120 that can be subjected to force are increased, which facilitates grasping and moving, thereby improving the grasping yield.

[0079] In one embodiment of the present application, the first display structure 110 also includes a first insulating layer 113, which is disposed between the first red light-emitting layer 111 and the first green light-emitting layer 112; the first insulating layer 113 can isolate the first red light-emitting layer 111 to prevent the electrical signal loaded into the first red light-emitting layer 111 from being transmitted to the first green light-emitting layer 112, thereby reducing mutual interference of signals therebetween.

[0080] The second display structure 120 further includes a second insulating layer 123 disposed between the second red light-emitting layer 121 and the first blue light-emitting layer 122. Similarly, the second insulating layer 123 can isolate the second red light-emitting layer 121 from the first blue light-emitting layer 122, preventing the electrical signal applied to the second red light-emitting layer 121 from being transmitted to the first blue light-emitting layer 122 and reducing the signal interference between the two. The first insulating layer 113 and the second insulating layer 123 are made of transparent materials, effectively ensuring that light can pass through smoothly.

[0081] In one embodiment of the present application, the first display structure 110 further includes a first semiconductor layer 114, a second semiconductor layer 115, a third semiconductor layer 116, a fourth semiconductor layer 117, and a third insulating layer 118. In the direction gradually away from the driving board 20, the third insulating layer 118, the first semiconductor layer 114, the first red light-emitting layer 111, the second semiconductor layer 115, the first insulating layer 113, the third semiconductor layer 116, the first green light-emitting layer 112, and the fourth semiconductor layer 117 are sequentially disposed. It can be seen that the first semiconductor layer 114 and the second semiconductor layer 115 are respectively disposed on the upper and lower surfaces of the first red light-emitting layer 111, and the third semiconductor layer 116 and the fourth semiconductor layer 117 are respectively disposed on the upper and lower surfaces of the first green light-emitting layer 112. One of the first semiconductor layer 114 and the second semiconductor layer 115 is a P-type semiconductor, and the other is an N-type semiconductor. One of the third semiconductor layer 116 and the fourth semiconductor layer 117 is a P-type semiconductor, and the other is an N-type semiconductor. Such an arrangement can form the movement of holes and electrons on the first display structure 110 when a voltage is applied, thereby ensuring that the first red light-emitting layer 111 and the first green light-emitting layer 112 can emit light.

[0082] The second display structure 120 further includes a fifth semiconductor layer 124, a sixth semiconductor layer 125, a seventh semiconductor layer 126, an eighth semiconductor layer 127, and a fourth insulating layer 128; in the direction gradually away from the driving board 20, the fourth insulating layer 128, the fifth semiconductor layer 124, the second red light-emitting layer 121, the sixth semiconductor layer 125, the second insulating layer 123, the seventh semiconductor layer 126, the first blue light-emitting layer 122, and the eighth semiconductor layer 127 are arranged in sequence. The fifth semiconductor layer 124 and the sixth semiconductor layer 125 are respectively arranged on the upper and lower surfaces of the second red light-emitting layer 121, and the seventh semiconductor layer 126 and the eighth semiconductor layer 127 are respectively arranged on the upper and lower surfaces of the first blue light-emitting layer 122. As can be seen from the above, one of the fifth semiconductor layer 124 and the sixth semiconductor layer 125 is a P-type semiconductor, and the other is an N-type semiconductor. One of the seventh semiconductor layer 126 and the eighth semiconductor layer 127 is a P-type semiconductor, and the other is an N-type semiconductor. When a voltage is applied, holes and electrons move on the second display structure 120, so as to ensure that the second red light-emitting layer 121 and the first blue light-emitting layer 122 can emit light.

[0083] In one embodiment of the present application, the first display structure 110 further includes a first electrode 101, a second electrode 102, and a first common electrode 103. One end of the first electrode 101 is connected to the driving layer 220 of the driving board 20, and the other end is connected to the fourth semiconductor layer 117. One end of the second electrode 102 is connected to the driving layer 220 of the driving board 20, and the other end is connected to the second semiconductor layer 115. One end of the first common electrode 103 is connected to the driving layer 220 of the driving board 20, and the other end is respectively connected to the first semiconductor layer 114 and the third semiconductor layer 116; through the first electrode 101, the electrical signal of the driving layer 220 can be loaded onto the fourth semiconductor layer 117, and the second electrode 102 can load the electrical signal of the driving layer 220 onto the second semiconductor layer 115. At the same time, since the first common electrode 103 is connected to both the first semiconductor layer 114 and the third semiconductor layer 116, a loop for the electrical signal to flow is formed from the first electrode 101 through the fourth semiconductor layer 117, the first green light-emitting layer 112, the third semiconductor layer 116, and the first common electrode 103 in sequence. A loop can also be formed from the second electrode 102 through the second semiconductor layer 115, the first red light-emitting layer 111, the first semiconductor layer 114, and the first common electrode 103.

[0084] The second display structure 120 further includes a third electrode 104, a fourth electrode 105, and a second common electrode 106. One end of the third electrode 104 is connected to the driving layer 220 of the driving board 20, and the other end is connected to the eighth semiconductor layer 127. One end of the fourth electrode 105 is connected to the driving layer 220 of the driving board 20, and the other end is connected to the sixth semiconductor layer 125. One end of the second common electrode 106 is connected to the driving layer 220 of the driving board 20, and the other end is respectively connected to the fifth semiconductor layer 124 and the seventh semiconductor layer 126. For the second display structure 120, a loop formed by the first display structure 110 can be referred to. For example, the driving layer 220 provides current. The specific current flow direction can be that the current flows through the third electrode 104, the eighth semiconductor layer 127, the first blue light-emitting layer 122, the seventh semiconductor layer 126 in sequence, and flows to the second common electrode 106, thereby forming a current circulation loop. The current of the fourth electrode 105 can flow through the sixth semiconductor layer 125, the second red light-emitting layer 121, the fifth semiconductor layer 124, and the second common electrode 106 in sequence, and can also form a current circulation loop.

[0085] In one embodiment of the present application, the first electrode 101, the second electrode 102, the first common electrode 103, the third electrode 104, the fourth electrode 105, and the second common electrode 106 are all columnar structures. Such as cylindrical or prismatic.

[0086] The first electrode 101 sequentially passes through the third insulating layer 118, the first semiconductor layer 114, the first red light-emitting layer 111, the second semiconductor layer 115, the first insulating layer 113, the third semiconductor layer 116, the first green light-emitting layer 112, and is connected to the fourth semiconductor layer 117; the second electrode 102 sequentially passes through the third insulating layer 118, the first semiconductor layer 114, and the first red light-emitting layer 111, and is connected to the second semiconductor layer 115; the first common electrode 103 sequentially passes through the third insulating layer 118, the first semiconductor layer 114, the first red light-emitting layer 111, the second semiconductor layer 115, and the first insulating layer 113, and is connected to the third semiconductor layer 116 and the first semiconductor layer 114. It can be seen therefrom that the first electrode 101, the second electrode 102, and the first common electrode 103 pass through the respective film layers from bottom to top, avoiding the arrangement of electrode lines on the outside of the structure, and can reduce the interference of the outside world on the signal transmission of the electrodes. In addition, the electrodes are arranged in the respective film layers, reducing the exposed area of the electrodes and the short-circuit risk between the electrodes of adjacent pixels, and further increasing the environmental working stability of the first display structure 110.

[0087] The third electrode 104 is sequentially disposed through the fourth insulating layer 128, the fifth semiconductor layer 124, the second red light-emitting layer 121, the sixth semiconductor layer 125, the second insulating layer 123, the seventh semiconductor layer 126, the first blue light-emitting layer 122, and is connected to the eighth semiconductor layer 127; the fourth electrode 105 is sequentially disposed through the fourth insulating layer 128, the fifth semiconductor layer 124, the second red light-emitting layer 121, and is connected to the sixth semiconductor layer 125; the second common electrode 106 is sequentially disposed through the fourth insulating layer 128, the fifth semiconductor layer 124, the second red light-emitting layer 121, the sixth semiconductor layer 125, the second insulating layer 123, and is connected to the eighth semiconductor layer 127 and the fifth semiconductor layer 124. Similarly, the third electrode 104, the fourth electrode 105, and the second common electrode 106 also pass through the respective film layers from bottom to top, reducing the interference effect of the outside world on the signal transmission of the electrodes. In addition, the electrodes are disposed in the respective film layers, reducing the exposed area of the electrodes, reducing the short-circuit risk between the electrodes of adjacent pixels, and further increasing the environmental working stability of the second display structure 120.

[0088] It should be emphasized here that the first common electrode 103 can form circuits with the first red light-emitting layer 111 and the first green light-emitting layer 112 respectively, and can transmit the electrical signals of the two circuits simultaneously. In this way, the situation of additionally disposing electrodes is reduced, the structure is simplified, and the overall structure of the first display structure 110 can be made smaller. Similarly, the second common electrode 106 can also transmit the signals of the second red light-emitting layer 121 and the first blue light-emitting layer 122 simultaneously, reducing the number of electrodes of the second display structure 120, which is beneficial to arranging more display sub-pixels 10 in the display module.

[0089] In one embodiment of the present application, the third insulating layer 118 includes a first flat portion 1181 and a first vertical portion 1182. The first flat portion 1181 is located between the first semiconductor layer 114 and the driving board 20. The first vertical portion 1182 is connected to the first flat portion 1181. The first vertical portion 1182 respectively surrounds the side wall surfaces of the first electrode 101, the second electrode 102, and the first common electrode 103, and respectively exposes the tops of the first electrode 101, the second electrode 102, and the first common electrode 103. Among them, the first vertical portion 1182 surrounding the first common electrode 103 is at least partially spaced from the first flat portion 1181, so that the first common electrode 103 contacts the first semiconductor layer 114; the top of the electrode refers to the end away from the driving board 20. Exposing the top of the first electrode 101 ensures that the first electrode 101 can be electrically connected to the fourth semiconductor. Similarly, the top of the second electrode 102 is exposed to ensure that the second electrode 102 can be electrically connected to the second semiconductor layer 115. Exposing the top of the first common electrode 103 enables the first common electrode 103 to be electrically connected to the third semiconductor layer 116. By having the first vertical portion 1182 and the first flat portion 1181 spaced apart and disconnected at the position of the first common electrode 103, the surface of the first common electrode 103 can contact the first semiconductor layer 114. In this way, the first common electrode 103 can transmit signals from the third semiconductor layer 116 and can also transmit signals from the first semiconductor layer 114. The position where the first vertical portion 1182 and the first flat portion 1181 are spaced apart and disconnected is only limited to the position where the first common electrode 103 faces the first semiconductor.

[0090] The fourth insulating layer 128 includes a second flat portion 1281 and a second vertical portion 1282. The second flat portion 1281 is located between the fifth semiconductor layer 124 and the driving board 20. The second vertical portion 1282 is connected to the second flat portion 1281. The second vertical portion 1282 respectively surrounds the side wall surfaces of the third electrode 104, the fourth electrode 105, and the second common electrode 106, and respectively exposes the tops of the third electrode 104, the fourth electrode 105, and the second common electrode 106. Among them, the second vertical portion 1282 surrounding the second common electrode 106 is at least partially spaced from the second flat portion 1281, so that the second common electrode 106 contacts the fifth semiconductor layer 124.

[0091] For the second display structure 120, the top end of the third electrode 104 is exposed to ensure that the third electrode 104 can be electrically connected to the eighth semiconductor. The top end of the fourth electrode 105 is exposed to ensure that the fourth electrode 105 can be electrically connected to the sixth semiconductor layer 125. The top end of the second common electrode 106 is exposed to electrically connect the second common electrode 106 to the seventh semiconductor layer 126. At the position of the second common electrode 106, the second vertical portion 1282 and the second flat portion 1281 are spaced apart and disconnected, so that the surface of the second common electrode 106 can contact the fifth semiconductor layer 124. In this way, the fifth common electrode can transmit signals from both the seventh semiconductor layer 126 and the fifth semiconductor layer 124.

[0092] In the above embodiment, the heights of the first electrode 101, the first common electrode 103, and the second electrode 102 decrease in sequence. The heights of the third electrode 104, the second common electrode 106, and the fourth electrode 105 can also decrease in sequence. The heights of the first electrode 101 and the third electrode 104 can be equal, the first common electrode 103 and the second common electrode 106 are equal, and the heights of the second electrode 102 and the fourth electrode 105 are equal.

[0093] In one embodiment of the present application, the first common electrode 103 includes a first main body portion 1031 and a first connection portion 1032. One end of the first connection portion 1032 is connected to the first main body portion 1031, and the other end is connected to the driving board 20. The first main body portion 1031 passes through the third insulating layer 118, the first semiconductor layer 114, the first red light-emitting layer 111, the second semiconductor layer 115, and the first insulating layer 113 and is connected to the third semiconductor layer 116. The first vertical portion 1182 surrounds the side wall surface of the first main body portion 1031. The diameter of the first connection portion 1032 is larger than the diameter of the first main body portion 1031. The first vertical portion 1182 and the first flat portion 1181 are spaced apart. The upper surface of the first connection portion 1032 contacts the first semiconductor layer 114. By making the diameter of the first connection portion 1032 larger than the diameter of the first main body portion 1031, the contact area between the lower end of the electrode and the driving board 20 can be larger, making the overall structure of the electrode more stable. Moreover, the upper surface of the first connection portion 1032 is not covered by an insulating layer and can be directly connected to the first semiconductor layer 114.

[0094] The second common electrode 106 includes a second main body portion 1061 and a second connection portion 1062.

The second main body portion 1061 passes through the fourth insulating layer 128, the fifth semiconductor layer 124, the second red light-emitting layer 121, the sixth semiconductor layer 125, the second insulating layer 123, and is connected to the eighth semiconductor layer 127. The second vertical portion 1282 surrounds the side wall surface of the second main body portion 1061. The diameter of the second connection portion 1062 is greater than that of the second main body portion 1061. The second vertical portion 1282 is spaced from the second flat portion 1281. The upper surface of the second connection portion 1062 is in contact with the fifth semiconductor layer 124. By making the diameter of the second connection portion 1062 greater than that of the second main body portion 1061, the contact and fixing area between the lower end of the electrode and the driving board 20 can be made larger, thereby making the overall structure of the electrode more stable. Moreover, the upper surface of the second connection portion 1062 is not covered by an insulating layer and can be directly connected to the fifth semiconductor layer 124.

[0095] In one embodiment of the present application, the third insulating layer 118 further includes a first surrounding portion 1183, and the first surrounding portion 1183 surrounds the sides of the first semiconductor layer 114, the first red light-emitting layer 111, the second semiconductor layer 115, the first insulating layer 113, the third semiconductor layer 116, the first green light-emitting layer 112, and the fourth semiconductor layer 117. The first surrounding portion 1183 can be connected to the first flat portion 1181. Through the arrangement of the first surrounding portion 1183, the sides of the first semiconductor layer 114, the first red light-emitting layer 111, the second semiconductor layer 115, the first insulating layer 113, the third semiconductor layer 116, the first green light-emitting layer 112, and the fourth semiconductor layer 117 are wrapped, reducing the loss of its own signals and also being able to reduce the interference of external signals on the first display structure 110. The first surrounding portion 1183 also plays a certain role in sealing and waterproofing, reducing the influence of water vapor on the light-emitting layer.

[0096] The fourth insulating layer 128 further includes a second surrounding portion 1283, and the second surrounding portion 1283 surrounds the sides of the fifth semiconductor layer 124, the second red light-emitting layer 121, the sixth semiconductor layer 125, the second insulating layer 123, the seventh semiconductor layer 126, the first blue light-emitting layer 122, and the eighth semiconductor layer 127. The second surrounding portion 1283 can be connected to the second flat portion 1281. By wrapping the sides of the fifth semiconductor layer 124, the second red light-emitting layer 121, the sixth semiconductor layer 125, the second insulating layer 123, the seventh semiconductor layer 126, the first blue light-emitting layer 122, and the eighth semiconductor layer 127 with the second surrounding portion 1283, it can also reduce the loss of its own signals and reduce the interference of external signals on the second display structure 120. The second surrounding portion 1283 can also play a certain role in sealing and waterproofing, reducing the influence of water vapor on the light-emitting layer.

[0097] In one embodiment of the present application, the first common electrode 103 and the second common electrode 106 are cathodes, and the first electrode 101, the second electrode 102, the third electrode 104, and the fourth electrode 105 are anodes; the first electrode 101 and the second electrode 102 are symmetrically arranged with the first common electrode 103 as the axis. In this way, the first electrode 101 and the second electrode 102 can be separated from each other to avoid signal interference between the first electrode 101 and the second electrode 102. The third electrode 104 and the fourth electrode 105 are symmetrically arranged with the second common electrode 106 as the axis. Similarly, the third electrode 104 and the fourth electrode 105 can also be separated from each other to avoid signal interference between the third electrode 104 and the fourth electrode 105.

[0098] In one embodiment of the present application, the first red light-emitting layer 111 and the second red light-emitting layer 121 are arranged in the same layer. For example, both the first red light-emitting layer 111 and the second red light-emitting layer 121 are close to the driving board 20, that is, the first red light-emitting layer 111 is arranged between the first green light-emitting layer 112 and the driving board 20, and the second red light-emitting layer 121 is arranged between the first blue light-emitting layer 122 and the driving board 20. It can also be that both the first red light-emitting layer 111 and the second red light-emitting layer 121 are far from the driving board 20, that is, the first red light-emitting layer 111 is arranged on the side of the first green light-emitting layer 112 away from the driving board 20, and the second red light-emitting layer 121 is arranged on the side of the first blue light-emitting layer 122 away from the driving board 20.

[0099] In addition, the layer heights of the first red light-emitting layer 111 and the second red light-emitting layer 121 are arranged staggeredly; for example, the first red light-emitting layer 111 is arranged between the first green light-emitting layer 112 and the driving board 20, while the second red light-emitting layer 121 is arranged on the side of the first blue light-emitting layer 122 away from the driving board 20. The first red light-emitting layer 111 is arranged on the side of the first green light-emitting layer 112 away from the driving board 20, while the second red light-emitting layer 121 is arranged between the first blue light-emitting layer 122 and the driving board 20.

[0100] The orthographic projection areas of the first red light-emitting layer 111 and the first green light-emitting layer 112 on the driving board 20 are the same, and the orthographic projection areas of the second red light-emitting layer 121 and the first blue light-emitting layer 122 on the driving board 20 are the same. From this, it can be known that the light-emitting areas of the first red light-emitting layer 111 and the first green light-emitting layer 112 are the same, and the light-emitting areas of the second red light-emitting layer 121 and the first blue light-emitting layer 122 are also the same. The edge of the first red light-emitting layer 111 is aligned with the edge of the first green light-emitting layer 112, and their facing areas can exactly overlap. The design of the side wall surface of the first display structure 110 with unevenness is reduced, and the side wall surface is relatively flat, which is convenient for grasping and moving the first display structure 110 and the second display structure 120. Moreover, the relatively flat side wall surface can also facilitate the placement and installation of the first display structure 110 and the second display structure 120, and reduce the interference with other adjacent display structures.

The second green light-emitting layer 132 and the second blue light-emitting layer 133 are stacked in a direction perpendicular to the driving layer 220 of the driving board; the orthographic projection area of the third red light-emitting layer 131 on the driving board is larger than the orthographic projection area of the second green light-emitting layer 132 on the driving board, and the orthographic projection area of the second green light-emitting layer 132 on the driving board is equal to the orthographic projection area of the second blue light-emitting layer 133 on the driving board; by the orthographic projection area of the third red light-emitting layer 131 on the driving board being larger than the orthographic projection area of the second green light-emitting layer 132 on the driving board, the light-emitting area of the third red light-emitting layer 131 can be larger, the light-emitting area of the third red light-emitting layer 131 is increased, and it is ensured that the third red light-emitting layer 131, the second green light-emitting layer 132, and the second blue light-emitting layer 133 can be effectively mixed to complete the picture display.

[0104] The first display structure 110 further includes a fifth insulating layer 134, a ninth semiconductor layer 135, and a tenth semiconductor layer 136. In the direction gradually away from the driving board, the fifth insulating layer 134, the ninth semiconductor layer 135, the third red light-emitting layer 131, and the tenth semiconductor layer 136 are arranged in sequence.

[0105] The second display structure 120 further includes a sixth insulating layer 137, an eleventh semiconductor layer 138, a twelfth semiconductor layer 139, a seventh insulating layer 141, a thirteenth semiconductor layer 142, and a fourteenth semiconductor layer 143.

[0107] In an embodiment of the present application, the connection electrodes further include a fifth electrode 144 and a sixth electrode 145. One end of the fifth electrode 144 is connected to the driving layer 220 of the driving board, and the other end is connected to the ninth semiconductor layer 135.

One end of the seventh electrode 146 is connected to the driving layer 220 of the driving board, and the other end is connected to the twelfth semiconductor layer 139. One end of the eighth electrode 147 is connected to the driving layer 220 of the driving board, and the other end is connected to the fourteenth semiconductor layer 143. One end of the third common electrode 148 is connected to the driving layer 220 of the driving board, and the other end is respectively connected to the eleventh semiconductor layer 138 and the thirteenth semiconductor layer 142.

[0108] The fifth electrode 144, the sixth electrode 145, the seventh electrode 146, the eighth electrode 147, and the third common electrode 148 are all columnar structures; the fifth electrode 144 passes through the fifth insulating layer 134 and is connected to the ninth semiconductor layer 135; the sixth electrode 145 sequentially passes through the fifth insulating layer 134, the ninth semiconductor layer 135, and the third red light-emitting layer 131 and is connected to the tenth semiconductor layer 136; the seventh electrode 146 sequentially passes through the sixth insulating layer 137, the eleventh semiconductor layer 138, the second green light-emitting layer 132 and is connected to the twelfth semiconductor layer 139; the eighth electrode 147 sequentially passes through the sixth insulating layer 137, the eleventh semiconductor layer 138, the second green light-emitting layer 132, the twelfth semiconductor layer 139, the seventh insulating layer 141, the thirteenth semiconductor layer 142, and the second blue light-emitting layer 133 and is connected to the fourteenth semiconductor layer 143; the third common electrode 148 sequentially passes through the sixth insulating layer 137, the eleventh semiconductor layer 138, the second green light-emitting layer 132, the twelfth semiconductor layer 139, and the seventh insulating layer 141 and is connected to the eleventh semiconductor layer 138 and the thirteenth semiconductor layer 142.
