[0002] Transparent MLED display technology involves bonding MiniLED or MicroLED chips onto a transparent substrate, giving the entire display screen a transparent characteristic.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9This application provides a conductive structure 100 suitable for mounting multiple light-emitting devices 200. Each light-emitting device 200 includes a common negative terminal 220 and at least one positive terminal 210. The conductive structure 100 includes a transparent conductive layer 120, on which an insulating pattern 130 is formed to divide the transparent conductive layer 120 into a positive conductive region 121 and a negative conductive region 122. The positive conductive region 121 is adapted to connect to at least one positive terminal 210, and the negative conductive region 122 is adapted to connect to the negative terminal 220. The transparent conductive layer 120 has multiple insulating lines 160 extending along a second direction Y, and the multiple insulating lines 160 are spaced apart along a first direction X, with adjacent insulating lines 160 forming mounting areas for the light-emitting devices 200. An insulating pattern 130 is provided in the mounting area of ​​each light-emitting device 200. The insulating pattern 130 is connected to the insulating lines 160 on both sides. The insulating pattern 130 divides the mounting area of ​​the light-emitting device 200 into a positive conductive area 121 and a negative conductive area 122.

[0031] For example, see Figure 2 A first light-emitting device 200 is mounted on the conductive structure 100. The light-emitting device 200 is a light source device formed by encapsulating a MiniLED chip. The light-emitting device 200 includes a positive terminal 210 and a negative terminal 220, and can independently display red, green, blue, and white light. The light-emitting device 200 is mounted on a transparent conductive layer 120 corresponding to the mounting area of ​​the light-emitting device 200. An insulating pattern 130 in the shape of an "I" is set on the transparent conductive layer 120, dividing the transparent conductive layer 120 into a positive conductive area 121 and a negative conductive area 122. The positive terminal 210 of the light-emitting device 200 is connected to the positive conductive area 121, and the negative terminal 220 of the light-emitting device 200 is connected to the negative conductive area 122.

[0032] For example, see Figure 1 , Figure 3 and Figure 5A second light-emitting device 200 is mounted on the conductive structure 100. The light-emitting device 200 is a light source formed by encapsulating Micro LED chips. The light-emitting device 200 is a MiP (Micro LED in Package) light source, integrating three high-brightness Micro LED chips (red, green, and blue) into the same package to form a single-pixel-level full-color light-emitting unit. The pins of the light-emitting device 200 are located at the bottom. Each Micro LED chip corresponds to an independent positive terminal 210, and the negative terminals of the three chips are connected to a common negative terminal 220. That is, the light-emitting device 200 has three positive terminals 210 and one common negative terminal 220. The three positive terminals 210 and the negative terminal 220 are arranged in a matrix. Besides mixing light to achieve white light, the MiP light source can also individually achieve monochromatic light or other colored light. Three positive terminals 210 are connected to the positive conductive region 121 of the transparent conductive layer 120, and a common negative terminal 220 is connected to the negative conductive region 122.

[0033] In this embodiment, by setting an insulating pattern 130 on the conductive structure 100, the conductive structure 100 is divided into a positive conductive region 121 and a negative conductive region 122. The positive terminal 210 of the light-emitting device 200 is connected to the positive conductive region 121, and the negative terminal 220 of the light-emitting device 200 is connected to the negative conductive region 122. The insulating pattern 130 is prepared by etching, which prevents the formation of metal lines on the transparent conductive layer 120, ensuring the light transmittance of the display film 300 and avoiding the absorption and scattering of light by metal lines, thus achieving the invisibility of the light source. It can match the multi-pin electrical connection requirements of the light-emitting device 200, and the wiring scheme is simple, reducing the processing difficulty and cost.

[0034] In some embodiments, see Figure 7 , Figure 8 and Figure 9 The conductive structure 100 includes a transparent substrate 110 and a transparent conductive layer 120, with the transparent conductive layer 120 disposed on at least one side of the transparent substrate 110. The transparent substrate 110 supports and protects the transparent conductive layer 120.

[0035] The transparent substrate 110 is made of one of the following materials: polyethylene terephthalate (PET), polyimide (PI), transparent polyimide (CPI), polycarbonate (PC), and polyethylene naphthalate (PEN). A transparent conductive layer 120 is formed by depositing a film on at least one side of the transparent substrate 110. The coating material is silver nanospheres (AgNSs), silver nanowires (AgNWs), ITO, carbon nanotubes (CNTs), conductive polymers (ICP), graphene (GPE), etc. Silver nanospheres or silver nanowires are chosen as coating materials for preparing the transparent conductive layer 120 because they possess excellent conductivity, high light transmittance, good stability, and low material and manufacturing costs.

[0036] A transparent conductive layer 120 located on one side of the transparent substrate 110 is divided into multiple independent display device mounting areas, which are arranged along the length or width direction of the transparent substrate 110. Each display device mounting area mounts a light-emitting device 200. An insulating pattern 130 is provided in each display mounting area, dividing the transparent conductive layer 120 within each area into a positive conductive area 121 and a negative conductive area 122. The positive conductive area 121 is adapted to connect to the positive terminal 210 of the light-emitting device 200, and the negative conductive area 122 is adapted to connect to the negative terminal 220 of the light-emitting device 200, thereby achieving precise conduction and electrical control of the positive and negative terminals of the light-emitting device 200.

[0037] In some embodiments, see Figure 9 The transparent substrate 110 has a transparent conductive layer 120 on both sides and a conductive through hole 140 penetrating the transparent conductive layer 120 and the transparent substrate 110. The two transparent conductive layers 120 are connected through the conductive through hole 140. An insulating pattern 130 is arranged around the conductive through hole 140 so that one of the transparent conductive layers 120 is a positive conductive area 121 and the other transparent conductive layer 120 is a negative conductive area 122.

[0038] For example, see Figure 9The transparent substrate 110 includes a first side 111 and a second side 112. The first side 111 is provided with a first transparent conductive layer 120A, and the second side 112 is provided with a second transparent conductive layer 120B. The first transparent conductive layer 120A has a plurality of insulating lines 160 extending along a second direction Y, and the plurality of insulating lines 160 are spaced apart along a first direction X. The second transparent conductive layer 120B also has a plurality of insulating lines 160 extending along the first direction X, and the plurality of insulating lines 160 are spaced apart along the second direction Y. An insulating pattern 130 is provided on the first transparent conductive layer, surrounding the transparent conductive via 140, such that the first transparent conductive layer 120A is a positive conductive region 121, and the second transparent conductive layer 120B is a negative conductive region 122. The light-emitting device 200 has three positive terminals 210 and a common negative terminal 220. The positive terminals 210 are electrically connected to the first transparent conductive layer 120A, and the negative conductive terminal 150 is electrically connected to the second transparent conductive layer 120B through the conductive via 140.

[0039] In this embodiment, wiring is performed on both sides of the transparent substrate 110, which significantly increases the density of the light-emitting device 200. When used to display images, this greatly improves the pixel density and enhances the display quality. Moreover, the three-dimensional wiring structure avoids the problems of wire congestion, short circuit risk, and complex cross-insulation caused by all lines being squeezed onto the same plane.

[0040] In some embodiments, see Figure 3 and Figure 4 The light-emitting device 200 includes multiple positive terminals 210. The positive conductive region 121 is adapted to connect all the positive terminals 210, and the negative conductive region 122 is adapted to connect the negative terminal 220, forming a conductive path that allows the red, green, and blue primary colors to be lit simultaneously and mixed to produce white light. The MiP light source achieves white light through RGB three-in-one light mixing. Typically, its single-sided size is less than 500um, resulting in higher transmittance of the display film 300, as well as better subjective transparency and invisibility, thus improving the viewing experience and user experience.

[0041] In some embodiments, see Figure 3 and Figure 4 The insulating pattern 130 includes a first end and a second end, as well as a continuous strip pattern connecting the first end and the second end, to divide the transparent conductive layer 120 into a positive conductive region 121 and a negative conductive region 122.

[0042] For example, see Figure 3Viewed from above, the insulating pattern 130 is shaped like a "「". The insulating pattern 130 consists of two perpendicular strip-shaped patterns, forming a right-angle bend. The insulating pattern 130 includes a horizontal extension and a vertical extension. The horizontal extension extends horizontally, and its length matches the size of a single MiP chip light source in that direction. The vertical extension extends vertically downward from one end of the horizontal extension. The widths of the horizontal and vertical extensions are the same.

[0043] For example, see Figure 4 Viewed from above, the insulating pattern 130 is arc-shaped. The arc-shaped stripes are symmetrically distributed, with one portion of the arc extending smoothly upwards and backwards in an arc, and another portion extending smoothly downwards and backwards in an arc. The inner side of the arc-shaped area enclosed by the insulating pattern 130 is the negative conductive region 122, which can accommodate the negative terminal 220 of the MiP chip; the outer side of the arc-shaped area enclosed by the insulating pattern 130 is the positive conductive region 121, surrounding the negative conductive region 122 and connected to the positive terminal 210.

[0044] In this embodiment, the insulating pattern 130 of the strip pattern has a clear boundary, realizing physical isolation and functional division between the positive conductive area 121 and the negative conductive area 122, effectively avoiding short circuits between the positive and negative electrodes, while shortening the connection distance between the MiP chip pins and the conductive areas, reducing contact resistance, improving current transmission stability, and reducing display flickering caused by poor contact. Combined with the small size of the MiP chip itself, the graininess of the light source is reduced; at the same time, the metal-free circuit design combined with the transparent conductive layer 120 makes the overall light transmittance of the display film 300 high, improving the light source invisibility effect.

[0045] In some embodiments, see Figure 5 and Figure 6 The light-emitting device 200 includes a plurality of positive terminals 210, and the positive conductive region 121 includes a plurality of mutually insulated sub-conductive regions 123. Each sub-conductive region 123 is adapted to connect to a positive terminal 210, so that the plurality of positive terminals 210 are respectively connected to the negative conductive region 122 to form a plurality of conductive paths.

[0046] For example, see Figure 5 and Figure 6The positive terminal 210 of the red light-emitting unit of the light-emitting device 200, the positive terminal 210 and its corresponding sub-conductive region 123, the negative terminal 220 and the negative conductive region 122 form a conductive path for controlling the brightness of the red light-emitting unit. Similarly, the positive terminal 210 of the green light-emitting unit of the light-emitting device 200, the positive terminal 210 and its corresponding sub-conductive region 123, the negative terminal 220 and the negative conductive region 122 form a conductive path for controlling the brightness of the green light-emitting unit. Likewise, the positive terminal 210 of the blue light-emitting unit of the light-emitting device 200, the positive terminal 210 and its corresponding sub-conductive region 123, the negative terminal 220 and the negative conductive region 122 form a conductive path for controlling the brightness of the blue light-emitting unit.

[0047] In this embodiment, by setting multiple sub-conductive regions 123 corresponding to multiple positive terminals 210, multiple conductive paths are formed, allowing for the adjustment of the grayscale levels of the three primary colors: red, green, and blue. Through the mixing of these three colors, each MiP light source (i.e., a pixel) can display any desired color, achieving true pixel-level full-color display. See also the embodiments described above. Figure 5 and Figure 6 The insulating pattern 130 includes a strip pattern that extends along a first direction X and along a second direction Y and is intersected, so as to divide a plurality of sub-conductive regions 123 and negative electrode conductive regions 122 on the transparent conductive layer 120.

[0048] For example, see Figure 5 Viewed from above, the insulating pattern 130 is in the shape of a cross. The insulating pattern 130 includes horizontal and vertical extensions that intersect at the center. The horizontal and vertical extensions have the same width. The dimensions of the horizontal and vertical extensions are designed according to the specifications of the optical device.

[0049] On the transparent conductive layer 120, a cross-shaped insulating pattern 130 divides the conductive area into three sub-conductive areas 123 and one negative conductive area 122. The sub-conductive areas 123 can correspond to multiple independent positive terminals 210 of the MiP chip light source, realizing precise docking of multiple positive terminals of a single chip; the negative conductive area 122 is connected to the chip's common negative terminal 220.

[0050] In this embodiment, the simple lines of the insulating pattern 130 reduce the difficulty of laser etching or photolithography fabrication, improving process uniformity and yield. Through the one-time cross-isolation of the horizontal and vertical patterns, four mutually insulated conductive regions are created. This perfectly matches the electrode arrangement requirements of a MiP light source with three independent positive electrodes and one common negative electrode, achieving electrical isolation under high-density integration and effectively avoiding signal crosstalk. The insulating pattern 130 clearly separates the current paths.

[0051] In some embodiments, see Figure 6 The insulating pattern 130 includes a polygonal structure formed by multiple arc-shaped strip patterns, and the arc-shaped strip patterns are arranged centrifugally to divide multiple sub-conductive regions 123 and negative electrode conductive regions 122 on the transparent conductive layer 120.

[0052] For example, viewed from above, the insulating pattern 130 is a quadrangular curved shape formed by four curved patterns with a certain arc or specific curvature. This clearly divides the transparent conductive layer into four mutually insulated, specially shaped electrode regions to accommodate the structure of the three positive terminals 210 and one negative terminal 220 of the light-emitting device 200.

[0053] The centrifugal setting of the arc-shaped strip pattern of the insulating pattern 130 eliminates sharp corners and achieves precise isolation of the four electrode areas in a small space with a compact graphic, ensuring reliable electrical insulation between the three positive electrode paths and one negative electrode path, thus meeting the fundamental requirements of high-density light-emitting device array integration 200.

[0054] In some embodiments, see Figure 7 , Figure 8 and Figure 9 The positive conductive region 121 and the negative conductive region 122 are provided with conductive terminals 150. The conductive terminals 150 are located on the side of the transparent conductive layer 120 away from the transparent substrate 110. The conductive terminals 150 are suitable for connection with the light-emitting device 200.

[0055] For example, the positive electrode conductive region 121 is provided with three conductive terminals 150, which are respectively connected to the three positive terminals 210 of the light-emitting device 200, and the negative electrode conductive region 122 is provided with one conductive terminal 150, which is connected to the negative terminal 220 of the light-emitting device 200.

[0056] In this embodiment of the application, by providing conductive terminals 150 on the transparent conductive layer 120, which are suitable for connection with the electrode pins of the light-emitting device 200, the problem of bonding between the transparent conductive layer 120 and the light-emitting device 200 is solved, and a reliable connection between the light-emitting device 200 and the conductive structure 100 is achieved.

[0057] In some embodiments, the transparent substrate 110 is a flexible transparent substrate.

[0058] The second aspect, see [link / reference]. Figures 1 to 9This application also provides a display film 300, including a light-emitting device 200 and a conductive structure 100 as described above. The light-emitting device 200 includes a plurality of positive terminals 210 and a common negative terminal 220. The light-emitting device 200 is mounted on a transparent conductive layer 120, with the positive terminals 210 connected to a positive conductive region 121 and the negative terminals positively connected to a negative conductive region 122. This display film 300 has all the beneficial effects of the conductive structure 100 described above, which will not be repeated here.

[0059] In some embodiments, see Figure 5 and Figure 6 The positive electrode conductive region 121 includes multiple sub-conductive regions 123. Each positive terminal 210 is connected to a sub-conductive region 123, so that the multiple positive terminals 210 are respectively connected to the negative terminal 220 to form multiple conductive paths.

[0060] The positive conductive region 121 on the conductive structure 100 is divided into multiple sub-conductive regions 123 by an insulating pattern 130. Each sub-conductive region 123 can be precisely connected to an independent positive terminal 210 of the light-emitting device 200 via a conductive terminal 150 and a bonding material. Simultaneously, the common negative terminal 220 of the light-emitting device 200 is connected to the negative conductive region 122 on the conductive structure 100. Thus, each positive terminal 210, together with its corresponding multiple positive terminals and common negative terminal of the light-emitting device 200, forms multiple independent conductive paths. By independently controlling the current flowing into each path, the brightness of each of the red, green, and blue colors can be precisely adjusted, thereby achieving color mixing and full-color display.

[0061] In some embodiments, see Figure 3 and Figure 4 Multiple positive terminals 210 are connected to the same positive conductive region 121, so that all positive terminals 210 and negative terminals 220 are connected to form a conductive path.

[0062] All positive terminals 210 on the conductive structure 100 are connected to the same, undivided positive conductive region 121. Simultaneously, the common negative terminal 220 is connected to the negative conductive region 122. All positive terminals 210 are connected in parallel through the unified positive conductive region 121, forming a single conductive path with the common negative terminal 220. When the circuit is on, current flows through this single path, simultaneously illuminating red, green, and blue light. The three primary colors are immediately mixed after emission to directly produce white light. The white light has good color quality, a high color rendering index, and uniform light shape. The system is stable and has high driving efficiency.

[0063] In some embodiments, see Figure 8The display film 300 also includes an encapsulation protective layer 500, which is disposed on the side of the light-emitting device 200 away from the conductive structure 100 and covers the light-emitting device 200. The encapsulation protective layer isolates water and oxygen to protect the light-emitting device 200.

[0064] Thirdly, see [the third aspect]. Figures 1 to 11 This application also provides a display device 400, including the display film 300 of any of the above-described embodiments. The display device 400 possesses all the beneficial effects of the aforementioned display film 300, which will not be elaborated upon here.

[0065] In some embodiments, see Figure 10 It also includes an adhesive film layer 410, which is disposed on at least one side of the display film 300. In some embodiments, the adhesive film layer 410 is gray-black or transparent.

[0066] The gray-black adhesive film layer 410 acts as a light-shielding layer, effectively absorbing stray light and ambient light from non-light-emitting areas of the display film 300. Although it sacrifices some transmittance, it improves the shielding properties of the light-emitting devices 200, enhancing their invisibility. This makes each individual light-emitting device 200 stand out more against a dark background, improving the overall contrast of the display and ensuring that the image remains clear and the colors vibrant even in bright environments (such as driving during the day). When applied to sunroofs, it can also provide sun protection and heat insulation.

[0067] The gray-black film layer 410 effectively absorbs and blocks infrared and visible light. When applied to a vehicle sunroof, it significantly reduces the heat from direct sunlight entering the cabin, improving air conditioning efficiency and passenger comfort, thus unifying display functionality with practical heat insulation. The display interface is transparent when viewed from inside the vehicle, while it appears dark when viewed from outside, effectively protecting passenger privacy.

[0068] In some embodiments, see Figure 10 and Figure 11 It also includes a glass substrate 420, with the adhesive film layer 410 disposed on the side away from the display film 300.

[0069] For example, see Figure 10 and Figure 11 The display film 300 has adhesive film layers 410 on both sides, and a glass substrate 420 is disposed on the side of the adhesive film layer 410 facing away from the display film 300. The glass substrate 420 serves as the material interface of the outermost layer of the display device 400, possessing characteristics such as high strength and high light transmittance. It can withstand vibration, impact, and scratches from daily cleaning in the automotive environment. Simultaneously, the display film 300 seals the space between the two glass substrates 420, isolating them from moisture, oxygen, and dust, greatly improving the product's long-term service life and environmental adaptability.

[0070] For the fourth aspect, see Figures 1 to 11 This application also provides a vehicle that includes the display device 400 described above. This vehicle possesses all the beneficial effects of the aforementioned display device 400, which will not be elaborated upon here.

[0071] The vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.

[0072] By combining the display device 400 with the automotive sunroof glass, and through the lamination or full bonding process of the transparent optoelectronic display film 300 with the glass, the entire sunroof can be upgraded into a huge dynamic display interface. This not only achieves a static "starry sky" effect, but also presents colorful dynamic patterns and information, enhancing the visual experience for drivers and passengers.

[0073] The transparent display film 300 can be integrated with dimming film technology to achieve a fusion of dynamic dimming and display functions. When needed, the canopy can serve as a high-definition display screen; when not in use, it can be restored to a transparent or completely light-blocking state, thus meeting both privacy and sunshade needs and achieving multi-functionality.

[0074] Thanks to the 300 display film technology, which enables ultra-high degree of freedom, pixel-level light-emitting array arrangement, and precise block control, its application scenarios can be greatly expanded to the fields of automotive lighting and interior / exterior trim. Combined with taillights, it can be used to design next-generation pixelated taillights with flowing animations, personalized light strips, and even simple information displays, significantly enhancing brand recognition and safety. Integrated with interior and exterior trim panels, it can realize hidden touch buttons, dynamic ambient lighting strips, welcome patterns, etc., creating a highly personalized and interactive cabin environment. It can be combined with rear windows, quarter windows, and other glass areas to display status information or advertisements; it can also be used for high-mounted brake lights to dynamically enhance the warning effect; and it can also serve as an interior / exterior information display screen, providing necessary prompts to drivers or pedestrians in appropriate locations.
