Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and an electronic device including the display panel. Background Art

[0002] In the field of display technology, a display panel generally includes a driving backplane and a plurality of light-emitting chips disposed on the driving backplane. The driving backplane controls the plurality of light-emitting chips to cooperate in emitting light to realize the display function of the display panel.

[0003] However, in the prior art, due to the structure of the light-emitting chip itself, the angle between the side wall of the light-emitting chip and the surface of the driving backplane may be obtuse or acute, thereby affecting the light uniformity of the light-emitting chip and further affecting the display effect of the display panel. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a display panel with enhanced display effect, and an electronic device including the display panel, which specifically includes the following technical solutions:

[0005] In a first aspect, an embodiment of the present application provides a display panel, comprising a driving backplane and a plurality of pixel units, wherein the plurality of pixel units are arranged on one side of the driving backplane, and the driving backplane is used to control the plurality of pixel units to emit light; each pixel unit comprises a first electrode and a second electrode arranged at intervals, and along the arrangement direction of the first electrode and the second electrode, a first circuit and a second circuit are arranged on the driving backplane, the first electrode of each pixel unit is electrically connected to the first circuit, and the second electrode of each pixel unit is electrically connected to the second circuit;

[0006] Along the arrangement direction of the first electrodes and the second electrodes, the first circuits connected to two adjacent pixel units are close to each other or the second circuits are close to each other.

[0007] The display panel of the present application is configured with a plurality of pixel units on a driving backplane, and the first electrode of the pixel unit is electrically connected to the first circuit of the driving backplane, and the second electrode of the pixel unit is electrically connected to the second circuit of the driving backplane, so that the driving backplane can control the transmission of electrical signals in the first circuit and the second circuit, thereby realizing the light emission control of each pixel unit and realizing the display function of the display panel of the present application.

[0008] The display panel of the present application also makes the arrangement of the two adjacent pixel units symmetrical by bringing the first circuit or the second circuit connected to the two adjacent pixel units close to each other so that the first electrodes or the second electrodes of the two pixel units are close to each other, thereby achieving the light emitting symmetry of the two adjacent pixel units and enhancing the display effect of the display panel of the present application.

[0009] In one embodiment, each pixel unit includes at least one light-emitting chip; along the arrangement direction of the first electrode and the second electrode, the light-emitting chip includes a first side wall and a second side wall relative to each other, the first side wall is close to the first electrode, and the angle between the first side wall and the surface of the driving backplane is a right angle or an obtuse angle; the second side wall is close to the second electrode, and the angle between the second side wall and the surface of the driving backplane is an acute angle.

[0010] In this embodiment, since the angle between the side wall of the light-emitting chip and the surface of the driving backplane may affect the light output intensity of the light-emitting chip, the side of the light-emitting chip close to the first side wall has a stronger light output intensity than the side of the light-emitting chip close to the second side wall. By bringing the first side wall close to the first electrode, the second side wall close to the second electrode, and when the first electrode or the second electrode is close to each other, the first side wall or the second side wall is also close to each other, the light emitted by the two light-emitting chips is relatively uniform, thereby improving the display effect of the display panel of the present application.

[0011] In one embodiment, along the arrangement direction of the first electrode and the second electrode, the wavelengths of the emitted light from the two light-emitting chips in two adjacent pixel units are within the same wavelength range.

[0012] In this embodiment, the wavelengths of the emitted light from the two light-emitting chips in the arrangement direction of the first electrode and the second electrode are set within the same wavelength range so that the colors of the light emitted by the two light-emitting chips in the arrangement direction are the same, thereby ensuring that the uniformity of the corresponding colors of light emitted from two adjacent pixel units is relatively high.

[0013] In one embodiment, along an arrangement direction perpendicular to the first electrode and the second electrode, the pixel unit includes at least three light-emitting chips arranged at intervals, and the wavelengths of emitted light from the at least three light-emitting chips are different.

[0014] In this embodiment, at least three light-emitting chips are arranged at intervals in a direction perpendicular to the arrangement of the first electrode and the second electrode, so that the light of different wavelengths emitted by the at least three light-emitting chips can cooperate with each other and form mixed colors, thereby emitting light of various colors outward, thereby enhancing the display effect of the display panel of the present application.

[0015] In one embodiment, each first electrode is connected to the first circuit, and the second electrode is connected to the respective second circuit; and / or each second electrode is connected to the first circuit, and the first electrode is connected to the respective first circuit.

[0016] In this embodiment, the first electrodes of the plurality of light-emitting chips are connected to the first circuit, and the second electrodes are connected to the second circuits, so that the driving backplane can control the electrical signals in the second circuits to achieve the control of the light emission of a single light-emitting chip in each pixel unit. On the other hand, the second electrodes of the plurality of light-emitting chips are connected to the second circuit, and the first electrodes are connected to the first circuits, so that the driving backplane can control the electrical signals in the first circuits to achieve the control of the light emission of a single light-emitting chip in each pixel unit.

[0017] In one embodiment, along an arrangement direction perpendicular to the first electrode and the second electrode, the arrangement order of the light emitting chips with different emission light wavelengths in each pixel unit is the same.

[0018] In this embodiment, the arrangement order of the light emitting chips in each pixel unit is set to be the same, so that the spacing between two adjacent light emitting chips that can emit light of the same wavelength is the same, thereby avoiding the situation where the light emitting areas of light of different wavelengths on two adjacent pixel units are inconsistent, thereby ensuring the display effect of the display panel of the present application.

[0019] In one embodiment, along a direction perpendicular to the arrangement direction of the first electrodes and the second electrodes, the first circuit connected to two adjacent pixel units is located on the same side of the pixel units along the arrangement direction of the first electrodes and the second electrodes.

[0020] In this embodiment, the first circuit connected to the two pixel units in the arrangement direction perpendicular to the first electrode and the second electrode is arranged on the same side, so as to ensure the display effect of the display panel of the present application in the arrangement direction of the first electrode and the second electrode, while facilitating the routing of the first circuit and the second circuit on the driving backplane.

[0021] In one embodiment, along a direction perpendicular to the arrangement direction of the first electrodes and the second electrodes, the first circuits connected to two adjacent pixel units are located on different sides of the pixel units along the arrangement direction of the first electrodes and the second electrodes.

[0022] In this embodiment, the first circuit connected to two pixel units in the arrangement direction perpendicular to the first electrode and the second electrode is arranged on different sides, so as to ensure the display effect of the display panel of the present application in the arrangement direction of the first electrode and the second electrode, and enhance the light emitting symmetry of two adjacent pixel units in the arrangement direction perpendicular to the first electrode and the second electrode, thereby further improving the display effect of the display panel of the present application.

[0023] In one embodiment, along the arrangement direction perpendicular to the first electrode and the second electrode, the light-emitting chip also includes a third side wall and a fourth side wall relative to each other, the angle between the third side wall and the surface of the driving backplane is a right angle or an obtuse angle, the angle between the fourth side wall and the surface of the driving backplane is an acute angle, and the third side walls of the light-emitting chips of two adjacent pixel units are close to each other or the fourth side walls are close to each other.

[0024] In this embodiment, since the angle between the side wall of the light emitting chip and the surface of the driving backplane in the arrangement direction perpendicular to the first electrode and the second electrode also affects the light output intensity of the light emitting chip, the side of the light emitting chip close to the third side wall has a stronger light output intensity than the side of the light emitting chip close to the fourth side wall. By bringing the third side wall or the fourth side wall of the light emitting chips of two adjacent pixel units close to each other, the uniformity of the light emitted by the two light emitting chips is relatively good, thereby improving the display effect of the display panel of the present application.

[0025] In a second aspect, an embodiment of the present application provides an electronic device, including a housing and a display panel, wherein the display panel is accommodated in the housing.

[0026] It can be understood that since the electronic device provided in the second aspect of the present application adopts the display panel provided in the first aspect of the present application, it also has the beneficial effect of enhancing the display effect.

[0051] See also Figure 1 The structure diagram of the electronic device 200 provided in one embodiment of the present application is shown.

[0052] like Figure 1 As shown, the electronic device 200 of the present application includes a housing 201 and a display panel 100. The housing 201 is used to accommodate and protect the display panel 100. The display panel 100 can emit light to the outside to realize the display function of the electronic device 200 of the present application.

[0053] See also Figure 2 FIG. 1 is a schematic diagram of a planar structure of a display panel 100 provided in one embodiment of the present application.

[0054] like Figure 2 As shown, the display panel 100 of the present application includes a driving backplane 10 and a plurality of pixel units 20, wherein the plurality of pixel units 20 are disposed on one side of the driving backplane 10 and are arranged in an array along a first direction 001 and a second direction 002, respectively, and each pixel unit 20 is electrically connected to the driving backplane 10. The first direction 001 and the second direction 002 are perpendicular to each other.

[0055] The driving backplane 10 can control the electrical signal to enter each pixel unit 20. It can be understood that when the driving backplane 10 controls the electrical signal to enter the pixel unit 20, the electrical signal can drive the pixel unit 20 to emit light, thereby realizing the display function of the display panel 100 of the present application.

[0056] For details, please refer to Figure 3 Another planar structural schematic diagram of a display panel 100 provided in an embodiment of the present application is shown.

[0057] like Figure 3 As shown, each pixel unit 20 includes a first electrode 21 and a second electrode 22, and the first electrode 21 and the second electrode 22 are arranged at intervals along a first direction 001. The driving backplane 10 includes a first circuit 11 and a second circuit 12, as shown in FIG. Figure 3 As shown, the first electrode 21 of each pixel unit 20 is electrically connected to the first circuit 11 , and the second electrode 22 of each pixel unit 20 is electrically connected to the second circuit 12 .

[0058] It can be understood that when the electrical signal of the external circuit can be input into the first electrode 21 and the second electrode 22 via the first circuit 11 and the second circuit 12 respectively, the input of the electrical signal is realized via the first electrode 21 and the second electrode 22, thereby realizing the light emission control of the pixel unit 20 by the driving backplane 10. Thus, the display function of the display panel 100 of the present application is realized.

[0059] In the first direction 001, there are multiple pixel units 20, including a first pixel unit 20a, a second pixel unit 20b and a third pixel unit 20c. Each pixel unit 20 includes multiple light-emitting chips 23. The multiple light-emitting chips 23 are arrayed on the surface of the driving backplane 10 along the second direction 002.

[0060] like Figure 3 As shown, for the first pixel unit 20a and the second pixel unit 20b, the second circuit 12 connected to the first pixel unit 20a and the second circuit 12 connected to the second pixel unit 20b are close to each other. That is, along the first direction 001, the two second circuits 12 connected to the two pixel units 20 are located between the two first circuits 11 connected to them.

[0061] It can be understood that, along the first direction 001 , the second electrodes 22 of the first pixel unit 20 a and the second pixel unit 20 b are close to each other, so that the first pixel unit 20 a and the second pixel unit 20 b are symmetrical along the center line therebetween.

[0062] When preparing the light-emitting chip 23, due to the preparation process and the properties of the preparation material itself, the prepared light-emitting chip 23 has inconsistent light brightness in the first direction 001. It can be understood that by placing the second circuit 12 connected to the first pixel unit 20a and the second circuit 12 connected to the second pixel unit 20b close to each other, the light-emitting chips 23 in the first pixel unit 20a and the second pixel unit 20b can be symmetrically distributed, so that the light emitted by the first pixel unit 20a and the second pixel unit 20b is more uniform. In this way, the polarization problem of the display panel 100 of the present application is improved.

[0063] like Figure 3 As shown, for the second pixel unit 20b and the third pixel unit 20c, the first circuit 11 connected to the second pixel unit 20b and the first circuit 11 connected to the third pixel unit 20c are close to each other.

[0064] It is understandable that the light emitting chips 23 in the second pixel unit 20b and the third pixel unit 20c are also symmetrically distributed, so that the light emitted by the second pixel unit 20b and the third pixel unit 20c is highly uniform, thereby improving the polarization problem of the display panel 100 of the present application.

[0065] Therefore, the display panel 100 of the present application makes the first circuit 11 or the second circuit 12 connected to two adjacent pixel units 20 close to each other, so that the first electrodes 21 and the second electrodes 22 of the two pixel units 20 are close to each other, so that the two adjacent pixel units 20 are arranged symmetrically, so that the light rays emitted by the two adjacent pixel units 20 are more symmetrical, thereby improving the display effect of the display panel 100 of the present application.

[0066] Understandably, Figure 3 In the subsequent schematic diagrams of the first circuit 11 and the second circuit 12 on the driving backplane 10 , in order to facilitate description of the connection relationship between the pixel unit 20 and the driving backplane 10 , dotted lines are used to represent the pixel unit 20 and the structure within the pixel unit 20 .

[0067] For details, please refer to Figure 4 The partial cross-sectional structure diagram of the display panel 100 provided in one embodiment of the present application is shown in FIG. Figure 5 Another partial cross-sectional structural diagram of a display panel 100 provided in an embodiment of the present application is shown in FIG. Figure 6 The cross-sectional view of the display panel 100 provided in one embodiment of the present application is shown in FIG. Figure 3 .

[0068] like Figure 3 , Figure 4, Figure 5 and Figure 6 As shown, the light emitting chip 23 includes a first semiconductor layer 232, a light emitting layer 233 and a second semiconductor layer 234 stacked in sequence. The first semiconductor layer 232 can provide electrons or holes for the light emitting chip 23, and correspondingly, the second semiconductor layer 234 can provide holes or electrons for the light emitting chip 23.

[0069] When the electric signal sent by the driving backplane 10 causes the light emitting chip 23 to conduct forwardly via the first electrode 21 and the second electrode 22, the current acting on the first semiconductor layer 232 causes the electrons or holes in the first semiconductor layer 232 to move toward the second semiconductor layer 234. Correspondingly, the current acting on the second semiconductor layer 234 causes the holes or electrons in the second semiconductor layer 234 to move toward the first semiconductor layer 232. At the same time, when the above-mentioned electrons and holes meet and combine, they radiate light outward, thereby achieving the purpose of emitting light.

[0070] At the same time, the light emitting layer 233 is used to carry electrons or holes emitted from the first semiconductor layer 232, and holes or electrons emitted from the second semiconductor layer 234. It can be understood that the light emitted by the light emitting chip 23 is emitted outward from the light emitting layer 233. On the other hand, the light emitting layer 233 also increases the overlap rate of electrons and holes, thereby improving the composite light emitting efficiency of the light emitting chip 23.

[0071] A first pad 235 is provided on the surface of the first semiconductor layer 232, and a second pad 236 is provided on the surface of the second semiconductor layer 234. The first pad 235 is electrically connected to the first electrode 21, and the second pad 236 is electrically connected to the second electrode 22. It can be understood that the electrical signal can enter the first semiconductor layer 232 and the second semiconductor layer 234 from the first pad 235 and the second pad 236 via the first electrode 21 and the second electrode 22, respectively, so as to drive the light-emitting chip 23 to emit light.

[0072] In the prior art, the light emitting chips 23 are usually arranged on the first surface of the wafer, and the light emitting chips 23 are cut from the wafer using a laser cutting process to form individual light emitting chips 23. However, since the crystal orientation of the substrate structure for making the light emitting chips 23 is not perpendicular to the first surface, during laser cutting, the sidewalls of the light emitting chips 23 formed by laser cutting are also not perpendicular to the first surface.

[0073] It is understandable that when the scratch angle between the side wall and the first surface is an obtuse angle or an acute angle, it will affect the proportion of the light-emitting layer 233 of the light-emitting chip 23. Thus, the light-emitting intensity of the light-emitting chip 23 is inconsistent in the first direction 001.

[0074] like Figure 4As shown, when the light emitting chip 23 used in the display panel 100 of the present application is a normal light emitting chip, the angle between the side wall of the light emitting chip 23 and the surface bracket of the driving backplane 10 may be an obtuse angle or an acute angle. Figure 5 As shown, when the light emitting chip 23 used in the display panel 100 of the present application is a flip-chip light emitting chip, the angle between the side wall of the light emitting chip 23 and the surface bracket of the driving backplane 10 may be an obtuse angle or an acute angle. Figure 6 As shown, when the light emitting chip 23 used in the display panel 100 of the present application is a vertical light emitting chip, the angle between the side wall of the light emitting chip 23 and the surface bracket of the driving backplane 10 may be an obtuse angle or an acute angle.

[0075] In this embodiment, along the first direction 001, the light emitting chip 23 includes a first side wall 2311 and a second side wall 2312 that are opposite to each other. Figure 4 , Figure 5 and Figure 6 As shown, the first angle A1 between the first side wall 2311 and the surface of the driving backplane 10 is an obtuse angle. It can be understood that along the first direction 001, the light emitting layer 233 on the side of the light emitting chip 23 close to the first side wall 2311 accounts for a relatively large proportion, so that the light emitting layer 233 emits more light from this side.

[0076] Correspondingly, such as Figure 4 , Figure 5 and Figure 6 As shown, the second angle A2 between the second side wall 2312 and the surface of the driving backplane 10 is an acute angle. It can be understood that along the first direction 001, the light emitting layer 233 on the side of the light emitting chip 23 close to the second side wall 2312 accounts for a relatively small proportion, so that the light emitted from the light emitting layer 233 from this side is small.

[0077] Along the first direction 001, the first electrode 21 is close to the first side wall 2311, and the second electrode 22 is close to the second side wall 2312. Based on the second circuits 12 connected to two adjacent pixel units 20 being close to each other, the second side walls 2312 of the light emitting chips 23 in the two adjacent pixel units 20 are close to each other. It can be understood that the sides with relatively weak light output intensity in the adjacent light emitting chips 23 are close to each other, so that the light emitted by the light emitting chips 23 can compensate each other, so that the light emitted by the two light emitting chips 23 is relatively uniform.

[0078] On the other hand, the first circuits 11 connected to two adjacent pixel units 20 can also be close to each other, so that the first side walls 2311 of the light-emitting chips 23 in the two adjacent pixel units 20 are close to each other. It can be understood that the sides of the adjacent light-emitting chips 23 with relatively strong light output intensity are close to each other, so that the light output of the light-emitting chips 23 is relatively concentrated, reducing the polarization phenomenon generated when the two pixel units 20 cooperate to emit light.

[0079] That is, the display panel 100 of the present application makes the light emitted by the two adjacent pixel units 20 symmetrical by bringing the first circuit 11 of the two adjacent pixel units 20 close to the first side wall 2311 close to each other, or brings the second circuit 12 of the two adjacent pixel units 20 close to each other on the second side wall 2312, thereby improving the symmetry of the light emitted by the two adjacent pixel units 20. This further improves the display effect of the display panel 100 of the present application.

[0080] It can be understood that in other embodiments, the first angle A1 between the first side wall 2311 and the surface of the driving back plate 10 is a right angle, and the second angle A2 between the second side wall 2312 and the surface of the driving back plate 10 is an acute angle.

[0081] See also Figure 7 FIG. 1 is a schematic diagram of a planar structure of a display panel 100 ′ in the prior art.

[0082] like Figure 7 As shown, in the prior art, the display panel 100' includes a driving backplane 10' and a plurality of pixel units 20'. The plurality of pixel units 20' are arranged on one side of the driving backplane 10', each pixel unit 20' includes a first electrode 21' and a second electrode 22' arranged at intervals, and the display panel 100' includes a first circuit 11' and a second circuit 12', the first electrode 21' is electrically connected to the first circuit 11', and the second electrode 22' is electrically connected to the second circuit 12', so that the driving backplane 10' can control the corresponding pixel unit 20' to emit light by controlling the electrical signals in the first circuit 11' and the second circuit 12'.

[0083] like Figure 7 As shown, the arrangement direction of the first electrode 21' and the second electrode 22' is a first direction 001. Along the first direction 001, the arrangement of the first circuit 11' and the second circuit 12' connected to two adjacent pixel units 20' is consistent.

[0084] In the prior art, when the light-emitting chip 23' in the pixel unit 20' of the display panel 100' adopts a face-up light-emitting chip, a flip-chip light-emitting chip, or a vertical light-emitting chip, due to the limitations of the preparation process and preparation materials of the light-emitting chip 23' during the preparation process, there is a situation where the angle between the side wall of the light-emitting chip 23' and the surface of the driving backplane 10' is an acute angle or an obtuse angle.

[0085] When two adjacent pixel units 20' along the first direction 001 emit light, the light intensities emitted by different regions of the two adjacent pixel units 20' along the first direction 001 are different, so that the light output brightness of the display panel 100' in different regions is inconsistent, affecting the light output uniformity of the display panel 100'.

[0086] Among them, Figure 8 As shown, in the first direction 001, when the light emitting chips 23' in two adjacent pixel units 20' cooperate to emit red light, green light and blue light respectively, the light of any color emitted by the light emitting chip 23' is not based on zero-point symmetry. That is, the symmetry of the light emitted by the light emitting chip 23' is poor, so that the light uniformity of the display panel 100' is poor.

[0087] On the other hand, Fig. 9 As shown, in the second direction 002, when the light emitting chips 23' in two adjacent pixel units 20' cooperate to emit red light, green light and blue light respectively, the light of any color emitted by the light emitting chip 23' is not symmetric based on the zero point. That is, the symmetry of the light emitted by the light emitting chip 23' is also poor, so that the light uniformity of the display panel 100' is poor.

[0088] The display panel 100 of the present application arranges pixel units 20 and places the first circuit 11 or the second circuit 12 connected to two pixel units 20 along the first direction 001 close to each other to improve the symmetry of the light emitted by two adjacent pixel units 20, so that the uniformity of the coordinated light emitted by the two adjacent pixel units 20 is relatively high, and the light emitted by the display panel 100 of the present application is relatively uniform, thereby improving the display effect of the display panel 100 of the present application.

[0089] Among them, Fig.10 As shown, in the first direction 001, when the light emitting chips 23 in two adjacent pixel units 20 cooperate to emit red light, green light and blue light respectively, compared with Figure 8 As shown, the light beams of different colors emitted by two adjacent pixel units 20 of the present application are symmetrical to each other, so that the light emission of the display panel 100 of the present application is relatively uniform.

[0090] On the other hand, Fig.11As shown, in the second direction 002, when the light emitting chips 23 in two adjacent pixel units 20 cooperate to emit red light, green light and blue light respectively, compared with Fig. 9 As shown, the light beams of different colors emitted by two adjacent pixel units 20 of the present application are symmetrical to each other, so that the light emission of the display panel 100 of the present application is relatively uniform.

[0091] See also Fig.12 FIG. 1 is a partial plan view of a display panel 100 provided in an embodiment of the present application, and FIG. Fig.13 Another partial plan view of a display panel 100 provided in one embodiment of the present application. Figure 3 .in, Fig.12 and Fig.13 is Figure 3 A partial enlarged schematic diagram of .

[0092] like Figure 3 , Fig.12 and Fig.13 As shown, along the first direction 001, the first pixel unit 20a and the second pixel unit 20b are arranged alternately. Fig.13 As shown, each pixel unit 20 has a plurality of light emitting chips 23 arranged along the second direction 002 , and each light emitting chip 23 is aligned one by one with the other light emitting chips 23 in the adjacent pixel unit 20 .

[0093] Along the first direction 001, a light emitting chip 23 in the first pixel unit 20a and another light emitting chip 23 in the second pixel unit 20b are spaced apart from each other and arranged in parallel. The wavelengths of the light emitted by the two light emitting chips 23 are within the same wavelength range.

[0094] The wavelength range of the emitted light is related to the emitted color of the light. It is understandable that by setting the emission wavelengths of the light emitting chips 23 in two adjacent pixel units 20 to be consistent, the colors of the light emitted by the two adjacent pixel units 20 can be the same, so that when the two pixel units 20 cooperate to emit the light of the color, the light emitted by the two pixel units 20 is symmetrical. This improves the display effect of the display panel 100 of the present application.

[0095] In one embodiment, if Fig.13 As shown, along the second direction 002, each pixel unit 20 includes a first light emitting chip 23a, a second light emitting chip 23b and a third light emitting chip 23c arranged at intervals. The wavelengths of the light emitted by the first light emitting chip 23a, the second light emitting chip 23b and the third light emitting chip 23c are all different, so that the light emitted by the first light emitting chip 23a, the second light emitting chip 23b and the third light emitting chip 23c have different colors.

[0096] It can be understood that the driving backplane 10 can control the first light-emitting chip 23a, the second light-emitting chip 23b and the third light-emitting chip 23c to emit light through the first circuit 11 and the second circuit 12, so that the first light-emitting chip 23a, the second light-emitting chip 23b and the third light-emitting chip 23c can cooperate with each other to form mixed colors, thereby increasing the color types of light emitted outward by the pixel unit 20 and enhancing the display effect of the display panel 100 of the present application.

[0097] like Fig.13 As shown, in this embodiment, the wavelength range of the light emitted by the first light-emitting chip 23a is 620nm-760nm, so that the first light-emitting chip 23a can emit red light. The wavelength range of the light emitted by the second light-emitting chip 23b is 492nm-577nm, so that the second light-emitting chip 23b can emit green light. The wavelength range of the light emitted by the third light-emitting chip 23c is 400nm-450nm, so that the third light-emitting chip 23c can emit blue light. Thus, the structure of the "R, G, B" three-primary color light-emitting chip is formed.

[0098] It is understandable that in other embodiments, the wavelength range, arrangement method and quantity of the light emitted by the first light emitting chip 23a, the second light emitting chip 23b and the third light emitting chip 23c can also be arbitrarily set based on the specific usage scenario of the product. The light emitting chip 23 in the pixel unit 20 can emit light of different colors and mix colors to form a display effect.

[0099] In another embodiment, in the second direction 002 , the number of the light emitting chips 23 in the pixel unit 20 may be set to be greater than three, and the applicant does not impose any special limitation on this.

[0100] In one embodiment, please refer to Figure 3 , the number of first circuits 11 connected to each pixel unit 20 is multiple, and the number of second circuits 12 connected to each pixel unit 20 is one. Each first circuit 11 is connected to each first electrode 21 one by one, so that the first circuit 11 controls the current of each light-emitting chip 23. Each second circuit 12 is connected to all second electrodes 22 in one pixel unit 20.

[0101] It is understandable that when the driving backplane 10 controls a single light emitting chip 23 in a single pixel unit 20 to emit light, the light emission control of the single light emitting chip 23 can be achieved by controlling the current in the first circuit 11 corresponding to the light emitting chip 23 .

[0102] In another embodiment, the number of first circuits 11 connected to each pixel unit 20 may be one, and the number of second circuits 12 connected to each pixel unit 20 may be multiple. When the driving backplane 10 controls a single light-emitting chip 23 to emit light, the light-emitting control of the single light-emitting chip 23 can be achieved by controlling the current in the second circuit 12 corresponding to the light-emitting chip 23.

[0103] It can be understood that in other embodiments, the number of the first circuit 11 and the second circuit 12 connected to each pixel unit 20 can be other, so that the light-emitting chips 23 in each pixel unit 20 can be connected in series and in parallel with each other through the first circuit 11 and the second circuit 12, so as to achieve different display effects of the display panel 100 of the present application.

[0104] See also Fig.14 The structure diagram of the display panel 100 provided in one embodiment of the present application is shown in FIG. Figure 3 .

[0105] like Figure 3 and Fig.14 As shown, in the second direction 002, there are adjacent first pixel units 20a and fourth pixel units 20d, the first light emitting chip 23a, the second light emitting chip 23b and the third light emitting chip 23c in the first pixel unit 20a are arranged in sequence along the second direction 002, and the first light emitting chip 23a, the second light emitting chip 23b and the third light emitting chip 23c in the fourth pixel unit 20d are arranged in sequence along the second direction 002. That is, in the second direction 002, the arrangement order of the light emitting chips 23 with different wavelengths of emitted light in each pixel unit 20 is the same.

[0106] It can be understood that the spacing between the first light emitting chip 23 a in the first pixel unit 20 a and the first light emitting chip 23 a in the fourth pixel unit 20 d is the same as the spacing between the remaining light emitting chips 23 .

[0107] When the arrangement order of the light emitting chips 23 in the fourth pixel unit 20d is different from the arrangement order of the light emitting chips 23 in the first pixel unit 20a, illustratively, when the light emitting chips 23 in the fourth pixel unit 20d are arranged in sequence as the third light emitting chip 23c, the second light emitting chip 23b and the first light emitting chip 23a, the spacing between the third light emitting chips 23c in two adjacent pixel units 20 becomes smaller, so that the light emitted by the third light emitting chip 23c is relatively concentrated. The spacing between the first light emitting chips 23a in two adjacent pixel units 20 becomes larger, so that the light emitted by the first light emitting chip 23a is relatively dispersed.

[0108] That is, along the second direction 002, when the arrangement order of the light emitting chips 23 with different emitted light wavelengths in two adjacent pixel units 20 is different, the spacing between the light emitting chips 23 that can emit light of the same wavelength in two adjacent pixel units 20 is different, so that when the two adjacent pixel units 20 cooperate to emit light, there is a situation where the light emitting areas of the light of different wavelengths are inconsistent. This affects the display effect of the display panel 100 of the present application.

[0109] Therefore, the arrangement order of the light-emitting chips 23 with different emitted light wavelengths in each pixel unit 20 is set to be the same in the second direction 002, which can ensure that when adjacent pixel units 20 cooperate to emit light, the light emitting areas of different wavelengths are the same, thereby improving the light emission uniformity of the display panel 100 of the present application in the second direction 002 and improving the display effect of the display panel 100 of the present application.

[0110] In one embodiment, if Figure 3 As shown, in the second direction 002 , the first circuits 11 connected to two adjacent pixel units 20 are located on the same side of the pixel unit 20 along the first direction 001 , and correspondingly, the second circuits 12 are located on the other side of the pixel unit 20 along the first direction 001 .

[0111] That is, in the second direction 002, the plurality of pixel units 20 are spaced apart to form a plurality of columns, wherein the first circuit 11 and the second circuit 12 connected to each column of pixel units 20 are arranged on both sides of each column of pixel units 20. This simplifies the first circuit 11 and the second circuit 12 on the driving backplane 10, and facilitates the routing of the first circuit 11 and the second circuit 12.

[0112] In one embodiment, if Fig.14 As shown, in the second direction 002, the first circuit 11 connected to the first pixel unit 20a and the second circuit 12 connected to the fourth pixel unit 20d are located on the same side. That is, the first circuits 11 connected to two adjacent pixel units 20 are located on different sides of the pixel unit 20 along the first direction 001.

[0113] Since the light emission brightness of the light emitting chip 23 in the second direction 002 is also inconsistent, it is understandable that the first circuits 11 connected to two adjacent pixel units 20 are arranged on different sides, thereby improving the symmetry of the light emission of the two adjacent pixel units 20 in the second direction 002.

[0114] For details, please refer to Fig.15 FIG. 1 is a partial schematic diagram of a display panel 100 provided in one embodiment of the present application. Fig.16 Another partial schematic diagram of a display panel 100 provided in an embodiment of the present application is shown, and Fig.17FIG. 1 is a partial cross-sectional schematic diagram of a display panel 100 provided in one embodiment of the present application.

[0115] like Fig.15 , Fig.16 and Fig.17 As shown, along the second direction 002, the light emitting chip 23 further includes a third side wall 2313 and a fourth side wall 2314. The third angle A3 between the third side wall 2313 and the surface of the driving backplane 10 is an obtuse angle, and the fourth angle A4 between the fourth side wall 2314 and the surface of the driving backplane 10 is an acute angle.

[0116] It can be understood that the inconsistency in the angles between the third side wall 2313 and the fourth side wall 2314 and the surface of the driving backplane 10 makes the light output brightness of the light-emitting chip 23 close to the third side wall 2313 and the side close to the fourth side wall 2314 inconsistent along the second direction 002.

[0117] Based on two pixel units 20 adjacent to each other in the second direction 002, the connected first circuits 11 are arranged on different sides. Fig.17 As shown, the fourth side walls 2314 of the light-emitting chips 23 in two adjacent pixel units 20 are close to each other, and the sides of the adjacent light-emitting chips 23 with relatively weaker light output intensity are close to each other, so that the light emitted by the light-emitting chips 23 can compensate each other, thereby improving the light output symmetry of the two adjacent pixel units 20.

[0118] On the other hand, the third side walls 2313 of the light-emitting chips 23 in two adjacent pixel units 20 can also be close to each other, so that the sides of the adjacent light-emitting chips 23 with relatively strong light output intensity are close to each other, so that the light emitted by the two adjacent pixel units 20 is relatively concentrated, thereby reducing the polarization phenomenon generated when the pixel units 20 cooperate to emit light.

[0119] It can be understood that in other embodiments, the third angle A3 between the third side wall 2313 and the surface of the driving back plate 10 is a right angle, and the fourth angle A4 between the fourth side wall 2314 and the surface of the driving back plate 10 is an acute angle.

[0120] Therefore, the second circuits 12 connected to two adjacent pixel units 20 in the first direction 001 are placed close to each other, and the first circuits 11 connected to two adjacent pixel units 20 in the second direction 002 are arranged on different sides, so that the multiple pixel units 20 arrayed on the surface of the driving backplane 10 are symmetrical with each other in the first direction 001 and the second direction 002, further improving the light output uniformity of the display panel 100 of the present application.

[0121] Among them, Fig.18As shown, in the first direction 001, when the light emitting chips 23 in two adjacent pixel units 20 cooperate to emit red light, green light and blue light respectively, compared with Fig.10 As shown, the light of different colors emitted by two adjacent pixel units 20 of the present application are more symmetrical, thereby further improving the light uniformity of the display panel 100 of the present application.

[0122] On the other hand, Fig.19 As shown, in the second direction 002, when the light emitting chips 23 in two adjacent pixel units 20 cooperate to emit red light, green light and blue light respectively, compared with Fig.11 As shown, the light of different colors emitted by two adjacent pixel units 20 of the present application are more symmetrical, thereby further improving the light uniformity of the display panel 100 of the present application.

[0123] In one embodiment, please refer to Figure 2 The display panel 100 further includes a retaining wall 30. In the first direction 001, the retaining wall 30 is disposed between two pixel units 20 connected to the first circuit 11 adjacent to each other. The retaining wall 30 is also disposed between two pixel units 20 adjacent to each other on the third side wall 2313. It can be understood that the provision of the retaining wall 30 prevents crosstalk of light emitted by adjacent pixel units 20, thereby enhancing the display effect of the display panel 100 of the present application.
