Description

[0001] Background Art and Technical Field

[0002] The present disclosure generally relates to an aesthetically pleasing micro LED lighting strip for a transportation vehicle.

[0003] The transportation industry is any industry, business, or institution that transports people or property from one place to another (whether by rail, highway, air, or water), and all associated operations and services in addition thereto; and also includes the storage or warehousing of goods or property, as well as the repair, parking, rental, maintenance, or cleaning of vehicles. The exterior of a vehicle can be the front, rear, side, top, or underside of any vehicle. In the transportation industry, there is a need for exterior aesthetic lighting, which requires a wide range of sizes, shapes, colors, etc., and needs to be attached to all areas of the exterior of the vehicle.

[0004] Currently, aesthetic lighting is provided by LEDs or bulbs, which are expensive and may be too bulky for some exterior components of the vehicle, resulting in limited locations where the aesthetic lighting can be positioned on the exterior of the vehicle.

[0005] Finally, the current aesthetic lighting in the transportation industry generates a large amount of heat, which may damage the aesthetic lighting or the main body parts or components of the vehicle over time. These aesthetic lighting devices also use a large amount of electricity to generate aesthetic lighting, which may pose a problem for vehicle owners.

[0006] Therefore, there is a need in the prior art to provide an aesthetically pleasing micro LED lighting strip for a transportation vehicle. Summary of the Invention

[0007] The present invention relates to a method of integrating an aesthetically pleasing micro LED lighting strip for a transportation vehicle, the method comprising: having a micro LED strip having a substrate, a plurality of micro LED splicing blocks, and a protective layer; having an adhesive strip in the micro LED strip; having a connecting member for connecting the micro LED splicing blocks, and wherein the micro LED lighting strip is attached to the transportation vehicle by the adhesive strip to provide the required lighting.

[0016] Embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which like reference numerals throughout several figures denote like elements and in which example embodiments are shown. However, the embodiments of the claims may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The examples set forth herein are non-limiting examples and are merely examples among other possible examples. The present disclosure describes a structure, system, and method for integrating micro-LED internal and external lighting into a transportation vehicle.

[0017] Figure 1AShows an example of integrating the microdevice 106 to be transferred with the electro-optic thin film device 112 in a hybrid structure. This is an example of an integrated micro-LED tile, which is later picked up and placed into an array of tiles. It should be clear to those skilled in the art that there are many ways to produce micro-LED tiles and integrate them into an array of tiles, such as in US20160218143A1 where microdevices are integrated into a system substrate. In multiple hybrid structure embodiments, an array of microdevices 106 is transferred onto a receptor substrate 102 and contact pads 104, and the thin film electro-optic device is integrated into the receptor substrate 102 and contact pads 104. The microdevice 106 can be transferred and bonded to the bond pads 104 of the receptor substrate 100. In one case, a dielectric layer 108 is formed over the substrate 102 to cover the exposed electrodes and conductive layers. Lithography and etching can be used to pattern the dielectric layer 108. Then, a conductive layer 110 is deposited and patterned to form the bottom electrode of the thin film electro-optic device 112. The dielectric layer 108 can be eliminated if there is no risk of unwanted coupling between the bottom electrode 110 and other conductive layers in the receptor substrate. However, this dielectric layer can also be used as a planarization layer to make the electro-optic device 112 easier to fabricate. A bulk layer 114 is deposited over the substrate 102 to cover the electrodes 110 and the edges of the microdevices 106. Then, the thin film electro-optic device 112 is formed over this structure. An organic light emitting diode (OLED) device is an example of a thin film electro-optic device, which can be formed using different techniques such as but not limited to shadow masking, lithography, and printed patterning. Finally, the top electrode 118 of the electro-optic thin film device 112 is deposited and patterned if needed. In embodiments where the thickness of the microdevice 106 is significantly high, cracking or other structural problems may occur within the bottom electrode 110. In these embodiments, the planarization layer can be used with or without the dielectric layer 108 to solve this problem.

[0018] In another embodiment, the microdevice 106 can have a device electrode 116. This electrode can be common among other microdevices 106 in the system substrate. In this case, the planarization layer (if present) and / or the bulk structure 114 cover the electrode 116 to avoid any short circuit between the electro-optic device 112 and the device electrode 116.

[0019] Figure 1BIllustrated is a structure in which devices are shared among several pixels (or sub - pixels) after post - processing to deposit a common electrode and a color - conversion layer. Here, the micro - device 106 is not fully patterned, but the horizontal situation is engineered such that the contacts 104 define the areas allocated to each pixel. The system substrate 102 has contact pads 104 and the donor substrate has micro - devices 106. After transferring the micro - devices 106 to the system substrate 102, post - processing such as depositing a common electrode 120, a color - conversion layer 122, color filters, etc. can be performed. However, the methods described in this disclosure and other possible methods can be used.

[0020] After forming the active regions, the described color - conversion layer can be added to the pixel (or sub - pixel) active regions. If the active regions of the pixels (or sub - pixels) are covered by a reflective layer, this can provide a higher fill factor and higher performance and avoid color leakage from the side pixels (or sub - pixels). In another embodiment, the micro - device 106 is grown on a buffer / sacrificial layer.

[0021] Figure 2 (including Figure 2A and Figure 2B ) shows an embodiment of a rigid flat micro - LED for external strip lighting.

In one example, the rigid substrate 202 can be a sapphire substrate on which an LED layer is grown monolithically on top, and the rigid substrate 202 can be a backplane having a circuitry for driving the micro-LED devices.

The micro-LED includes a number of micro-LEDs that are self-emitting per display pixel. The micro-LED is a modular technology. For example, the panel consists of tiny red, green, and blue LEDs and is connected to form a larger whole. In some embodiments, the micro-LED segments 204 can be produced in multiple sizes to increase the width of the micro-LED strip 201. The adhesive tape 206 can be a tape having a substance such as glue, starch, paste, adhesive, etc., which binds the micro-LED strip to another material by adhering to the surfaces of the micro-LED strip 201 and the other material to provide aesthetic lighting, the other material such as the exterior of a vehicle. The protective layer 208 can be a casing for protecting the micro-LED strip 201 from environmental elements or conditions. The protective layer 208 can be made of glass, silicon, plastic, etc., where an anti-glare protective film covers the micro-LED strip 201 and the micro-LED segments 204. For example, the protective layer 208 can be silicon dioxide SiO2 or another suitable material that can be deposited over the micro-LED segments 204 and / or the micro-LED strip 201 via physical vapor deposition, chemical vapor deposition, or spin coating processes.
