The light-emitting device is the light-emitting device mentioned above. The display device in this embodiment includes the light-emitting device mentioned above and also has the technical effect of the light-emitting device mentioned above.

[0164] The present invention is described in detail below with reference to specific examples.

[0165] Example 1

[0166] This embodiment provides a light emitting device, referring to Figure 1 The light emitting device includes a transparent layer 100, a plurality of light emitting elements arranged at intervals, a driving chip 300, and more than two pads.

[0167] The transparent layer 100 may have a light transmittance of more than 60% in the visible light range. Optionally, the transparent layer 100 may be a transparent substrate, and the transparent substrate may be a light-transmitting substrate such as PET, glass, quartz, sapphire, transparent ceramic, etc. The light-emitting device needs to have a certain thickness for easy use by the client, so the thickness of the transparent layer 100 is preferably greater than 10μm, and specifically preferably 30μm to 50μm, 50μm to 100μm or 100μm to 300μm. Referring to Figure 3, the transparent layer 100 includes a first surface 101 and a second surface 102 arranged opposite to each other, and the first surface 101 is the light-emitting surface of the entire light-emitting device. A light-emitting element and a driving chip 300 are arranged on the second surface 102 of the transparent layer 100.

[0168] Reference Figure 1 and 3a ~3b, a plurality of light-emitting elements are arranged on the second surface 102 of the transparent layer 100. Since different light-emitting elements usually have different thicknesses, an adhesive layer (not shown in the figure) is arranged between the transparent layer 100 and the light-emitting element, wherein the material of the adhesive layer can be an elastic material such as silicone, so that the light-emitting element is partially sunken into the adhesive layer to keep the electrode surface of the light-emitting element at the same level, and the height difference of the light-emitting surface of each light-emitting element can be reduced, so that the light emitted from the side of the light-emitting element is absorbed by the filling layer 400 described below as much as possible, so as to improve the contrast of the light-emitting device. The thickness of the adhesive layer is preferably 1μm to 15μm or 3μm to 10μm. If the thickness of the adhesive layer is greater than 15μm, the alignment accuracy of the light-emitting element may be affected.

[0169] The light-emitting element in this embodiment mainly refers to a micron-sized light-emitting diode, whose width or length ranges from 2 to 5 μm, 5 to 10 μm, 10 to 20 μm, 20 to 50 μm or 50 to 100 μm, and whose thickness ranges from 2 to 15 μm, preferably 5 to 10 μm.

[0170] Specifically, each light-emitting element includes a semiconductor stack layer, which may include a first semiconductor layer, a second semiconductor layer, and an active layer arranged in sequence, wherein the first semiconductor layer is an N-type semiconductor layer, the second semiconductor layer is a P-type semiconductor layer, and the active layer is a multi-layer quantum well layer, which can provide red light, green light, or blue light radiation. The N-type semiconductor layer, the multi-layer quantum well layer, and the P-type semiconductor layer are only the basic constituent units of the light-emitting element, on this basis, the light-emitting element may also include other functional structural layers that have an optimizing effect on the performance of the light-emitting element.

[0171] In this embodiment, refer to Figure 1, the plurality of light-emitting elements include a first light-emitting element 201, a second light-emitting element 202, and a third light-emitting element 203. The first light-emitting element 201, the second light-emitting element 202, and the third light-emitting element 203 radiate light of different wavelength ranges, respectively, and have different driving voltages. For example, the first light-emitting element 201 radiates blue light, the second light-emitting element 202 radiates green light, and the third light-emitting element 203 radiates red light, wherein the driving voltage difference between the light-emitting element radiating blue light and green light and the light-emitting element radiating red light is relatively large. In one embodiment, different light-emitting elements may have different semiconductor stacking layers, so as to directly radiate light of different wavelength ranges, and the specific material of the semiconductor stacking layer is selected according to the wavelength of the radiated light, including but not limited to aluminum gallium arsenide, gallium arsenide phosphide, aluminum gallium indium phosphide, gallium nitride, indium gallium nitride, zinc selenide, or gallium phosphide. In another embodiment, different light-emitting elements may have the same semiconductor stacked layers. For example, the semiconductor stacked layers in the first light-emitting element 201, the second light-emitting element 202 and the third light-emitting element 203 all radiate blue light, and a wavelength conversion layer is set on the light-emitting surface of the second light-emitting element 202 to convert the radiated blue light into green light, and a wavelength conversion layer is set on the light-emitting surface of the third light-emitting element 203 to convert the radiated blue light into red light.

[0172] Each light emitting element further includes a first electrode 210 and a second electrode 220. The semiconductor stack layer has a mesa exposing the first semiconductor layer, the first electrode 210 is formed on the mesa and electrically connected to the first semiconductor layer, and the second electrode 220 is formed on the second semiconductor layer and electrically connected to the second semiconductor layer.

[0173] Reference Figure 1 and 3a 3b, the driver chip 300 is also disposed on the second surface 102 of the transparent layer 100, and is spaced apart from the light-emitting element. The driver chip 300 is used to process data signals between the controller and the pixel point. The driver chip 300 is provided with a plurality of terminals, and each light-emitting element is electrically connected to a different terminal on the driver chip 300. Optionally, the driver chip 300 is an active driver IC chip. The use of an active driver IC chip can improve the display quality of the light-emitting module, and can be driven at a lower driving voltage, thereby increasing the service life of the display panel.

[0174] Optionally, the positions of the driver chip 300 and the light-emitting elements on the transparent layer 100 can be arbitrary, as long as they do not affect the arrangement of other structures. In the present embodiment, the driver chip 300 is arranged at the center of the transparent layer 100, and the three light-emitting elements are arranged on one side of the driver chip 300 as a light-emitting portion. In order to avoid the driver chip 300 being too large in size and occupying too much space of the entire light-emitting device, which affects the light output of the light-emitting portion. The size of the driver chip 300 is between about 1μm and 100μm. Specifically, the size of the driver chip 300 can be 5μm, 10μm, 20μm, 50μm, 70μm or 100μm. Optionally, the thickness of the driver chip 300 is less than 50μm. In order to facilitate the transfer of the driver chip 300 and the light-emitting element to the transparent layer 100, the difference in thickness between the driver chip 300 and the light-emitting element is less than 50 μm, for example, less than 25 μm, or less than 15 μm, which can effectively improve the transfer yield of the driver chip 300 and the light-emitting element to the transparent layer 100. Optionally, the thickness of the driver chip 300 is greater than the thickness of the light-emitting element, and the thickness of the driver chip 300 is less than or equal to 5 times the thickness of the light-emitting element. If the thickness of the driver chip 300 is much greater than the thickness of the chip, it is not conducive to the preparation of the stacked structure formed on the two later.

Among them, the first terminal 301 to the third terminal 303 can be connected to three light-emitting elements respectively and used to control the switches of the light-emitting elements, the fourth terminal 304 is a positive power terminal, the fifth terminal 305 is a negative power terminal, the sixth terminal 306 is a timing signal input terminal, and the seventh terminal 307 is a data signal input terminal. However, the number and order of the terminals of the driver chip 300 are not limited thereto, that is, the number and function of the terminals of the driver chip 300 can be designed according to the needs of the functions of the light-emitting device.

[0176] Optionally, refer to Figure 1 and 3a 3b, the light emitting device further comprises a filling layer 400, which is disposed on the sidewalls of the light emitting element and the sidewalls of the driving chip 300, and can prevent color mixing or light interference between adjacent light emitting elements to improve the contrast of the light emitting device.

The wiring layer 500 may be a single layer or multiple layers made of at least one material selected from titanium, copper, chromium, nickel, gold, platinum, aluminum, titanium nitride, tantalum nitride or tantalum. In the present embodiment, the wiring layer 500 comprises a two-layer structure, specifically a first layer 511 and a second layer 512, the first layer 511 is in direct contact with the light emitting element and the driving chip 300, and the second layer 512 is formed on the first layer 511. The first layer 511 is used to adhere the second layer 512 to the light emitting element, the driving chip 300 and the filling layer 400, and the second layer 512 mainly plays a conductive role. The material of the first layer 511 includes, but is not limited to, one or more of titanium, nickel, titanium nitride, tantalum nitride or tantalum, and the material of the second layer 512 includes, but is not limited to, one or more of copper, aluminum or gold. The wiring layer 500 can be prepared by sputtering, evaporation, etc. In this embodiment, the wiring layer 500 includes nine sub-wirings, and the nine sub-wirings include a first sub-wiring 501, a second sub-wiring 502, a third sub-wiring 503, a fourth sub-wiring 504, a fifth sub-wiring 505, a sixth sub-wiring 506, a seventh sub-wiring 507, an eighth sub-wiring 508 and a ninth sub-wiring 509. The sub-wirings are spaced apart and insulated from each other.

[0178] Reference Figure 1In the embodiment of the present invention, two or more pads are provided on the wiring layer 500. The two or more pads include a first pad 701, a second pad 702 and other pads. The first light emitting element 201 and the second light emitting element 202 are connected to the first pad 701, and the third light emitting element 203 is connected to the second pad 702, so that the third light emitting element 203 having a driving voltage different from that of the first light emitting element 201 and the second light emitting element 202 is driven separately. In the present embodiment, the other pads include a third pad 703, a fourth pad 704 and a fifth pad 705. The first pad 701 is connected to the first electrode 210 of the first light emitting element 201 and the first electrode 210 of the second light emitting element 202 through the first sub wiring 501. The second pad 702 is connected to the first electrode 210 of the third light emitting element 203 through the second sub wiring 502, and the second pad 702 is connected to the fourth terminal 304 of the driver chip 300 through the sixth sub wiring 506. The third pad 703 is connected to the fifth terminal 305 through the seventh sub-wiring 507, the fourth pad 704 is connected to the sixth terminal 306 through the eighth sub-wiring 508, and the fifth pad 705 is connected to the seventh terminal 307 through the ninth wiring. The light-emitting element is also electrically connected to the driver chip 300 through the wiring layer 500. Specifically, the second electrode 220 of the first light-emitting element 201 is connected to the first terminal 301 through the third sub-wiring 503, the second electrode 220 of the second light-emitting element 202 is connected to the second terminal 302 through the fourth sub-wiring 504, and the second electrode 220 of the third light-emitting element 203 is connected to the third terminal 303 through the fifth sub-wiring 505. The first pad 701 (VGB) is electrically connected to the first light-emitting element 201 and the second light-emitting element 202, and a driving voltage is input thereto, and the second pad 702 (VR) is electrically connected to the third light-emitting element 203 and the driver chip 300, so as to simultaneously input a driving voltage to the third light-emitting element 203 and the driver chip 300. The first light-emitting element 201 and the second light-emitting element 202 are blue light-emitting elements and green light-emitting elements, respectively, and the third light-emitting element 203 is a red light-emitting element. Since the driving voltage required for the red light-emitting element is quite different from the driving voltage of the blue light-emitting element and the green light-emitting element, driving the red light element alone can avoid unnecessary power consumption caused by simultaneous driving, which is beneficial to saving energy consumption; and it can also avoid damage to the light-emitting element caused by mismatching of the driving voltage, which is beneficial to the reliability and service life of the light-emitting element. The third pad 703 (Row / Clk) and the fourth pad 704 (Col / Data) are connected to the driver chip 300 by inputting data signals and timing signals, and the fifth pad 705 (Gnd) is electrically connected to the driver chip 300 for grounding. The switches of the three light-emitting elements are controlled by the first terminal 301, the second terminal 302 and the third terminal 303. The light-emitting device emits light with a specific brightness based on the driving voltage.

[0179] Optionally, an insulating layer 600 is further formed on the wiring layer 500, and openings corresponding to the number of pads are formed on the insulating layer 600. The pads can be arranged in the openings and exposed on the surface of the insulating layer; or they can be formed inside the openings of the insulating layer. Figure 3a As shown, the first pad 701 is disposed on the second layer 512 of the wiring layer 500, and the first pad 701 extends out from the insulating layer 600 and is exposed on the surface of the insulating layer 600. In one example, as Figure 3b As shown, the first pad 701 is disposed on the second layer 512 of the wiring layer 500, and the first pad 701 is relatively thin and is disposed in the opening of the insulating layer 600, but is not exposed to the surface of the insulating layer 600. At this time, the first pad 701 is a thin metal protective layer plated on the wiring layer 500 to prevent oxidation of the wiring layer and is used as a pad. Optionally, the material of the first pad 701 is NiAu.

[0180] It should be noted that the spacing between pads needs to be controlled within a reasonable range to avoid the influence between adjacent pads and the yield of the light-emitting device. For example, the spacing between adjacent pads can be controlled to be greater than 60 μm to avoid the influence between adjacent pads.

[0181] The encapsulation layer 600 is filled around the pad to electrically isolate adjacent sub-pads. The encapsulation layer 600 is a light-absorbing adhesive layer. For example, the encapsulation layer 600 is formed by dispersing black filling components in transparent or translucent materials such as silicone, epoxy resin, polyimide, low-temperature glass, polysiloxane, and polysilazane. The black filling components in the encapsulation layer 600 include, but are not limited to, carbon black, titanium nitride, iron oxide, ferroferric oxide, iron powder, and the like.

Moreover, the second pad 702 in this embodiment is only connected to the first electrode 210 of the third light-emitting element 203, and the sixth pad 706 is connected to the fourth terminal 304 of the driver chip 300. In this embodiment, the second pad 702 in Example 1 is split into the second pad 702 and the sixth pad 706 in this embodiment, so that the third light-emitting element 203 and the driver chip 300 can be driven separately through different pads, avoiding unnecessary power consumption when the driving voltages of the two are inconsistent. Furthermore, the light-emitting device includes six pads, and every three pads are evenly distributed on both sides of the light-emitting device, which is beneficial to the uniformity and reliability of subsequent solid crystal.

When the voltage input to the EN terminal through the sixth pad 706 reaches a preset value, such as 1.8V, the row data and the column data can directly reach the light-emitting device to drive the light-emitting device. If there is no EN terminal, the logic signal in front of the driver IC will be very complex and the reliability will be low. Furthermore, in this embodiment, an EN terminal is added to the driver chip 300 as a driving switch for the light-emitting device, and the light-emitting device can be directly driven through the EN terminal, avoiding the situation where other driving methods are more complex and the driving reliability is low, further reducing the power consumption of the light-emitting device, and improving the reliability of the device.

The first pad 701 is connected to the first electrode 210 of the first light-emitting element 201, the second light-emitting element 202, and the third light-emitting element 203 through the first sub-wiring 501, and is also connected to the fourth terminal 304 of the driving chip 300 through the fifth sub-wiring 505.
