[0079] As shown in FIG. 1, some embodiments of the present disclosure provide a display device 1000, which can be any device that displays whether motion (e.g., video) or fixed (e.g., still image) and whether text or image.

[0080] More specifically, it is contemplated that the described embodiments can be implemented in or in association with a variety of electronic devices, such as (but not limited to) mobile telephones, wireless devices, personal data assistants (PDAs), hand-held or portable computers, GPS receivers / navigators, cameras, MP4 video players, camcorders, game consoles, watches, clocks, calculators, television monitors, flat panel displays, computer monitors, auto displays (e.g., odometer display, etc.), cockpit controls and / or displays, display of camera views (e.g., in a vehicle), electronic photographs, electronic billboards or signs, projectors, architectural structures, packaging, and aesthetic structures (e.g., display of images on a piece of jewelry), and the like.

[0081] In some examples, as shown in FIG. 1, the display device 1000 can be a portable display product. For example, the display device 1000 can be a mobile phone as shown in FIG. 1.

[0082] In yet other examples, as shown in FIG. 2, the display device 1000 can be a wearable device. For example, the display device 1000 can be a watch as shown in FIG. 2.

[0083] In some embodiments, as shown in FIGS. 3 and 4, the display device 1000 includes a display substrate 100, a driving circuit board 200, a housing 300, and a cover plate 400.

[0084] The cover plate 400 is arranged on the light-emitting side of the display substrate 100. The driving circuit board 200 is arranged on the non-light-emitting side of the display substrate 100 and is connected to the display substrate 100 to provide a light-emitting signal to the display substrate 100.

[0085] The display substrate 100 has opposite light-emitting and non-light-emitting sides 100A and 100B. The light-emitting side 100A refers to the side of the display substrate 100 from which light can be emitted (the upper side of the display substrate 100 in FIGS. 3 and 4), and the non-light-emitting side 100B refers to the other side opposite the light-emitting side 100A (the lower side of the display substrate 100 in FIGS. 3 and 4).

[0086] In addition, the housing 300 can have a box-like structure with an opening. The display substrate 100 and the driving circuit board 200 can be arranged in the housing 300, and the cover plate 400 is arranged on the light-emitting side of the display substrate 100 and located at the opening of the housing 300.

[0087] It can be understood that the display device 1000 described above can be a micro light emitting display device (English: Mini / Micro Light Emitting Display, abbreviated: MLED).

[0088] At this time, the display substrate 100 can be used as a display panel of a micro light emitting display device and directly display. The display substrate 100 can emit light of multiple colors (e.g., red, blue, and green) to achieve full-color display.

[0089] In the following, some embodiments of the present disclosure will be described exemplarily taking the display device 1000 as a micro light emitting display device as an example, but the embodiments of the present disclosure are not limited thereto, and any other display device can also be considered as long as the same technical idea is applied.

[0090] In some embodiments, as shown in FIG. 5, the display substrate 100 includes a driving backplane 10 and a plurality of light-emitting components 20. The plurality of light-emitting components 20 are arranged on the driving backplane 10.

[0091] As shown in FIG. 5, the plurality of light-emitting components 20 are arranged in multiple rows and multiple columns. Each row includes at least two light-emitting components 20 arranged along a first direction X, and each column includes at least two light-emitting components 20 arranged along a second direction Y. The first direction X and the second direction Y intersect, for example, the first direction X and the second direction Y are perpendicular.

[0092] In some examples, the light emitting components 20 emit light of the same color, so that the display substrate 100 emits light of one color, and the display substrate 100 functions as a backlight in a liquid crystal display device to provide backlight for the display panel 500.

[0093] In other examples, the light emitting components 20 emit red light, blue light and green light, so that the display substrate 100 can emit light of multiple colors to realize full-color display.

[0094] In some embodiments, as shown in FIGS. 6 and 7, the light emitting component 20 includes a first substrate 21, a plurality of pixel circuits 22 and a plurality of light emitting devices 23 which are sequentially stacked.

[0095] The first substrate 21 can be a flexible first substrate 21 or a rigid first substrate 21. The material of the first substrate 21 can include a polymer resin or glass. For example, the first substrate 21 can be flexible, and the material of the first substrate 21 can include one of a polymer resin such as Polyethersulfone (PES), Polyarylate (PAR), Polyetherimide (PEI), Polyethylene Naphthalate Two Formic Acid Glycol Ester (PEN), Polyethylene Terephthalate (PET), Polyphenyl Sulfide Granula (PPS), Polyimide (PI), Polycarbonate (PC) and Cellulose Acetate Propionate (CAP). For example, the first substrate 21 can be rigid, and the material of the first substrate 21 can include a glass material containing SiO2 as a main component.

[0096] In some embodiments, the light emitting device 23 and the pixel circuit 22 are connected, so that the driving backplane 10 can drive the light emitting device 23 to emit light through the pixel circuit 22.

[0097] The plurality of light emitting devices 23 includes a first light emitting device, a second light emitting device, and a third light emitting device. The first light emitting device is configured to emit light of a first color, the second light emitting device is configured to emit light of a second color, and the third light emitting device is configured to emit light of a third color. The first color, the second color, and the third color form three primary colors, for example, the first color is blue, the second color is green, and the third color is red.

[0098] In some examples, the first light emitting device directly emits light of the first color, the second light emitting device directly emits light of the second color, and the third light emitting device directly emits light of the third color.

[0099] In other examples, as shown in FIGS. 6 and 7, the plurality of light emitting devices 23 directly emit light of the same color, which is blue. In this case, the display substrate 100 further includes a color conversion layer 30, which can include red quantum dot material, green quantum dot material, and transparent material. Blue light emitted by the display substrate 100 passes through the red quantum dot material and is converted to red light, blue light passes through the green quantum dot material and is converted to green light, and blue light can directly pass through the transparent material. For example, the first light emitting device corresponds to the red quantum dot material, the second light emitting device corresponds to the green quantum dot material, and the third light emitting device corresponds to the transparent material. In this way, the light emitting assembly 20 can emit red light, blue light, and green light.

[0100] In some examples, as shown in FIGS. 6 and 7, the color conversion layer 30 includes a defined portion 31 and an optical function portion 32. The defined portion 31 has a plurality of openings 311 defined thereon, and one optical function portion 32 is located in one opening 311. The material of the optical function portion 32 includes quantum dots, which can emit predetermined color light under an additional electric field or light pressure. For example, quantum dots can absorb short-wave blue light and emit long-wave red light and green light. This characteristic allows quantum dots to change the color of light emitted by a light source.

[0101] On the basis of the above-described embodiments, as shown in FIGS. 6 and 7, the display substrate 100 further includes a filter layer 40, which includes a plurality of filter portions 41 and a first light shielding layer 42. The plurality of filter portions 41 includes a first filter portion, a second filter portion, and a third filter portion. For example, the first filter portion is a blue filter portion, the second filter portion is a green filter portion, and the third filter portion is a red filter portion (for example, the first filter portion can only transmit blue light, the second filter portion can only transmit green light, and the third filter portion 41 can only transmit red light). The filter layer 40 is configured to filter blue light entering the filter layer 40, so that three primary color light used for color display can pass through, thereby achieving full-color display. The first light shielding layer 42 is arranged between different filter portions 41 and is configured to separate the filter portions 41 to prevent color mixing between different filter portions 41 and affect the display effect.

[0109] In some embodiments, as shown in FIG. 7, the light emitting assembly 20 further includes a light emitting device stack 201. The light emitting device stack 201 is located on the side of the plurality of pixel circuits 22 away from the first substrate 21. Along a direction perpendicular to the first substrate 21 and away from the first substrate 21, the light emitting device stack 201 includes a first semiconductor layer 2011, a light emitting functional layer 2012, and a second semiconductor layer 2013 stacked.

[0117] In the case where the display device 1000 includes the color conversion layer 30 and the filter layer 40, the color conversion layer 30 is located on the side of the plurality of light-emitting devices 23 away from the driving backplane 10. The filter layer 40 is located on the side of the color conversion layer 30 away from the plurality of light-emitting devices 23, and the color conversion layer 30 and the filter layer 40 are located between the second substrate 204 and the light-emitting device stack 201, i.e., the filter layer 40 and the color conversion layer 30 both belong to a part of the light-emitting assembly 20.

[0118] In some embodiments, as shown in FIGS. 6 and 7, each pixel circuit 22 includes a plurality of transistors 221 and a storage capacitor 222 (Capacitor, C).

[0119] The transistors 221 used in the circuit provided by the embodiments of the present disclosure can be thin film transistors, field effect transistors, or other switching devices with the same characteristics, and the embodiments of the present disclosure are all described by taking thin film transistors as an example.

[0140] Based on the pixel circuit 22 structure described above, in the case of a high gray scale, the pixel circuit 22 adopts a pulse amplitude modulation (PAM) mode to control the luminous brightness of the light emitting device 23. In the case of a low gray scale, the pixel circuit 22 adopts a pulse amplitude modulation (PAM) mode and a pulse width modulation (PWM) mode in combination to control the luminous brightness of the light emitting device 23. In this way, the pixel circuit 22 can display more diversified gray scale values, and improve the uniformity of the display panel brightness.

[0141] It should be noted that in the case of mixing red light, blue light and green light into equal-energy white light, the brightness of the green light is greater than the brightness of the red light, and the brightness of the red light is greater than the brightness of the blue light. For example, the ratio of the brightness of the green light, the brightness of the red light and the brightness of the blue light is 4.5:1:0.06. The brightness of the light emitted by the light emitting device 23 is proportional to the driving current generated by the connected pixel circuit 22. Among them, the equal-energy white light has equal radiant energy at each wavelength in the visible light spectrum

[0142] In some embodiments, in the case that the first light emitting device is used to emit blue light, the second light emitting device is used to emit green light, and the third light emitting device is used to emit red light,

[0329] In some examples, as shown in FIG. 12, the pulse width signal line HL overlaps the second power signal line VSL, and is arranged away from the first power signal line VDL, the scan signal line GL, the light-emitting signal line EL, the reset signal line RL, the first data signal line DL1, the second data signal line DL2 and the third data signal line DL3.

[0330] In this way, the parasitic capacitance of the pulse width signal line HL can be reduced, the voltage drop of the pulse width signal line HL is reduced, the risk of mura of the display panel is reduced, and the display effect of the display device 1000 is improved.

That is, the positions of the second power conductive parts 249 and the first data conductive parts 241 in the above-mentioned embodiments are exchanged.

[0332] In yet some embodiments, as shown in FIG. 14, the first conductive part 24 in the first row and the first column is a first power conductive part 248, the first conductive part 24 in the first row and the second column is a pulse width conductive part 247, the first conductive part 24 in the first row and the third column is a second power conductive part 249, the first conductive part 24 in the second row and the first column is a first data conductive part 241, the first conductive part 24 in the second row and the third column is a reset conductive part 245, the first conductive part 24 in the third row and the first column is a scan conductive part 244, the first conductive part 24 in the third row and the second column is a second data conductive part 242, and the first conductive part 24 in the third row and the third column is a third data conductive part 243. That is, the positions of the scan conductive part 244 and the first data conductive part 241 in the above embodiments are exchanged, and the positions of the second power conductive part 249 and the first data conductive part 241 are exchanged.

[0333] In some embodiments, as shown in FIG. 15, the light emitting assembly 20 further comprises a first connection line 29. The first connection line 29 comprises a first sub-section 291 and a second sub-section 292. In the orthogonal projection onto the first substrate 21, the first sub-section 291 overlaps the first through hole 1, and the second sub-section 292 is arranged away from the first through hole 1. The line width of the first sub-section 291 is greater than the line width of the second sub-section 292.

[0334] In this way, the line width of the part of the first connection line 29 overlapping the first through hole 1 is greater, which can reduce the risk of breakage or disconnection of the first connection segment EL1. Thus, the service life of the display device is improved.

[0335] In some examples, the difference between the line width of the first connection segment EL1 and the line width of the second sub-section 292 is 0.5 μm to 1 μm. For example, the difference between the line width of the first connection segment EL1 and the line width of the second sub-section 292 is 0.5 μm, 0.6 μm, 0.7 μm, 0.8 μm, 0.9 μm or 1 μm.

For example, the first connection line 29 comprises the light emitting signal line EL.

[0337] In some embodiments, on the basis of the above embodiments, as shown in FIG. 16, the light emitting assembly 20 further comprises a second connection line 26. In the orthogonal projection onto the first substrate 21, the distance between the first sub-section 291 and the second connection line 26 is greater than the distance between the second sub-section 292 and the second connection line 26.

[0338] In this way, the risk of breakage or disconnection of the first connection segment EL1 can be reduced. Thus, the service life of the display device is improved.

[0339] It can be understood that the second connection line 26 can be arranged in the same layer as the first connection segment EL1, or the second connection line 26 can be arranged in a different layer from the first connection segment EL1.

[0340] In some examples, as shown in FIG. 15, the distance between the first subsegment 291 and the second connection line 26 is greater than the distance between the second subsegment 292 and the second connection line 26 by 2-5 μm in the orthographic projection onto the first substrate 21. For example, the distance between the first subsegment 291 and the second connection line 26 is greater than the distance between the second subsegment 292 and the second connection line 26 by 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, or 5 μm.

[0341] In some examples, as shown in FIG. 16, the second connection line 26 is used to connect the driving transistor T1 of the second pixel circuit 224, the first light-emitting control transistor T4 of the second pixel circuit 224, and the second light-emitting control transistor T5 of the second pixel circuit 224.

[0342] In some embodiments, the light-emitting assembly further includes a third connection line adjacent to the first via and the first connection line is located in a layer of conductive layers. In this way, the risk of breakage or disconnection of the first connection segment EL1 can be reduced, thereby improving the service life of the display device. Wherein the third connection line adjacent to the first via means that there is no other connection line between the third connection line and the first via.

[0343] In some embodiments, as shown in FIG. 7, the orthographic projection of the second electrode 231 on the first substrate 21 is staggered with the orthographic projection of the first via 1 on the first substrate 21. In this way, the risk of the second electrode 231 being recessed can be reduced, the difficulty of bonding the second electrode 231 and the light-emitting device 23 can be reduced, and the bonding yield of the first electrode 25 and the light-emitting device 23 can be improved.

[0344] In some examples, the orthographic projection of the second electrode 231 on the first substrate 21 is located within the orthographic projection of the first electrode 25 on the first substrate 21. The orthographic projection of the first electrode 25 on the first substrate 21 overlaps the first via 1, and the portion of the first electrode 25 overlapping the second electrode 231 is staggered with the orthographic projection of the first via 1 on the first substrate 21, i.e., the portion of the first electrode 25 for fixing the second electrode 231 is staggered with the first via.

[0345] In some examples, as shown in FIG. 17, one conductive portion 24 corresponds to one first through-hole 1, i.e., the light emitting assembly 20 has nine first through-holes 1, and the plurality of first through-holes 1 are arranged in three rows and three columns. One conductive portion 24 corresponding to one first through-hole 1 means that one conductive portion 24 is connected to the pixel circuit 22 through one first through-hole 1.

[0346] In addition, in the orthographic projection to the first substrate 21, the first electrode 25 is located between two adjacent rows of first through-holes 1, and / or the first electrode 25 is located between two adjacent columns of first through-holes 1.

[0347] In some embodiments, as shown in FIGS. 6 and 7, the end of the first through-hole 1 away from the pixel circuit 22 layer is located within the range of the conductive portion 24. In this way, the area of the first through-hole 1 exposing the conductive portion 24 can be increased, thereby increasing the reliability of the connection of the conductive portion 24 to the pixel circuit 22.

[0348] In some embodiments, as shown in FIGS. 7 and 17, the plurality of first electrodes 25 includes a plurality of anode sub-electrodes 251 and one cathode sub-electrode 252, and the anode of one light emitting device 23 is connected to one anode sub-electrode 251, and the cathodes of a plurality of light emitting devices 23 are all connected to the cathode sub-electrode 252.

[0349] In this way, the number of first electrodes 25 can be reduced, the size of the light emitting assembly 20 can be reduced, and the number of light emitting assemblies 20 can be increased, which is beneficial to improve the display effect of the display device 1000.

[0350] In some examples, as shown in FIG. 17, the plurality of first electrodes 25 includes a first anode sub-electrode 2511, a second anode sub-electrode 2512, a third anode sub-electrode 2513, and a cathode sub-electrode 252. The first anode sub-electrode 2511 is connected to the first power supply conductive portion 248 and the anode of the first light emitting device, the second anode sub-electrode 2512 is connected to the first power supply conductive portion 248 and the anode of the second light emitting device, the third anode sub-electrode 2513 is connected to the first power supply conductive portion 248 and the anode of the third light emitting device, and the cathode sub-electrode 252 is connected to the second power supply conductive portion 249, the cathode of the first light emitting device, the cathode of the second light emitting device, and the cathode of the third light emitting device.

[0351] As shown in FIG. 17, the first anode sub-electrode 2511 is located between the first column of conductive portions 24 and the second column of conductive portions 24, and between the second row of conductive portions 24 and the third row of conductive portions 24. The second anode sub-electrode 2512 is located between the second column of conductive portions 24 and the third column of conductive portions 24, and between the second row of conductive portions 24 and the third row of conductive portions 24. The third anode sub-electrode 2513 is located between the first column of conductive portions 24 and the second column of conductive portions 24, and between the first row of conductive portions 24 and the second row of conductive portions 24. The cathode sub-electrode 252 is located between the second column of conductive portions 24 and the third column of conductive portions 24, and between the first row of conductive portions 24 and the second row of conductive portions 24.

[0352] In some embodiments, the first substrate 21 is a flexible substrate.

[0353] In some embodiments, the projection of the second semiconductor layer 2013 on the first substrate 21 covers the orthographic projection of the plurality of conductive portions 24 on the first substrate 21. In this way, in the case of binding the light emitting assembly 20 and the driving backboard 10, the first semiconductor layer 2011 can provide support for the conductive portions 24, thereby reducing the risk that the conductive portions 24 and the driving backboard 10 cannot be connected.

[0354] In some embodiments, as shown in FIG. 18, the light emitting assembly 20 further comprises a support 27, the support 27 is located between the pixel circuit 22 and the light emitting device 23, the orthographic projection of the support 27 on the first substrate 21 surrounds the plurality of first electrodes 25, and is located within the orthographic projection of the first semiconductor layer 2011 on the first substrate 21.

[0355] In this way, in the case of connecting the light emitting device 23 and the pixel circuit 22, the support 27 is used to support the light emitting device 23, which can reduce the risk that the light emitting device 23 is deformed and the light emitting device 23 and the pixel circuit 22 cannot be connected.

[0356] In some embodiments, as shown in FIG. 17, the first electrode 25 and the support 27 are made of the same material and are arranged in the same layer. In this way, the uniformity of the materials in the light emitting assembly 20 can be improved, and the manufacturing cost of the light emitting assembly 20 can be reduced.

[0357] In some embodiments, as shown in FIG. 7, the light emitting assembly 20 further comprises an adapter block 28, the adapter block 28 comprises a first adapter portion 281 and a second adapter portion 282 connected to each other. The first adapter portion 281 is at least partially located in the first through hole 1 and connected to the conductive portion 24, and the second adapter portion 282 is located outside the first through hole 1 and connected to the transistor 221 in the pixel circuit 22 layer.

[0358] In this way, the depth of the via hole in the pixel circuit 22 can be reduced, the difficulty of manufacturing the via hole can be reduced, the risk that the pixel circuit 22 and the conductive part 24 cannot be connected can be reduced, and the service life of the display panel can be improved. The pixel circuit 22 is connected to the via block 28 through the via hole.

[0359] In some embodiments, as shown in FIG. 7, the first via part 281 completely covers the first via hole 1. In this way, the first via part 281 and the first via hole 1 have a larger contact area, and the reliability of the connection between the first via part 281 and the conductive part 24 can be improved.

[0360] In some examples, the second via part 282 is located on the side of the first via part 281, and in the orthographic projection onto the first substrate 21, the second via part 282 protrudes away from the center of the first via hole 1 towards the boundary of the first via part 281. In this way, the area available for wiring of the light emitting assembly 20 can be increased.

[0361] In some embodiments, the light emitting assembly 20 includes a third semiconductor layer and a fourth semiconductor layer. The material of the third semiconductor layer includes low-temperature polysilicon, and the material of the fourth semiconductor layer includes an oxide semiconductor material.
