Description

[0001] Background Art and Technical Field

[0002] The present disclosure generally relates to micro-LED lighting in automotive applications.

[0003] Due to the brightness required for vehicle tail lights, they typically occupy a large volume at the rear of the vehicle.

[0004] Tail lights can be costly, especially on larger vehicles or vehicles with computerized tail light controls.

[0005] As a byproduct of generating light, tail lights produce heat. This heat is wasted energy and can be harmful to the vehicle and human operator.

[0006] Tail lights can be bulky and add weight, reducing the vehicle's speed, gas efficiency, and aerodynamics. They also make their storage and transportation more costly.

[0007] While not the most expensive replacement part on a vehicle, tail lights can still be costly, depending on the tail light technology used on the vehicle. The replacement cost of some bulbs can be as high as $100 each, and some traditional LED tail lights may require the replacement of the entire tail light assembly. Summary of the Invention

[0008] The present invention relates to a method of integrating micro-LEDs into a vehicle tail light, the method comprising: providing a micro-LED panel composed of a plurality of micro-LEDs; bonding a substrate to the micro-LED die; providing a connector that allows the electronics of the micro-LED panel to be integrated with the vehicle; and causing the micro-LED panel to perform the function of a vehicle tail light.

[0017] Embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which like reference numerals refer to like elements throughout the several views, 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 and other possible examples. The embodiments also relate to structures, systems, and methods for interior and exterior lighting in an automobile.

[0018] Figure 1AAn example of integrating the transfer microdevice 106 with the electro-optic thin film device 112 in a hybrid structure is shown. This is an example of an integrated micro-LED die that is later picked up and placed into a die array. It should be apparent to those skilled in the art that there are many ways to generate micro-LED dies and integrate them in a die array according to US20160218143A1 - Microdevice integration into system substrate. In multiple hybrid structure embodiments, the receptor substrate 102 and contact pads 104 onto which the microdevice 106 array is transferred and into which the thin film electro-optic device is integrated. The microdevice 106 can be transferred and bonded to the bonding 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. The dielectric layer 108 can be patterned using photolithography and etching. Then, a conductive layer 110 is deposited and patterned to form the bottom electrode of the thin film electro-optic device 112. If there is no risk of unwanted coupling between the bottom electrode 110 and other conductive layers in the receptor substrate, the dielectric layer 108 can be eliminated. However, this dielectric layer can also be used as a planarization layer to provide better fabrication of the electro-optic device 112. A bank layer 114 is deposited on the substrate 102 to cover the edges of the electrodes 110 and the microdevice 106. Then, the thin film electro-optic device 112 is formed over this structure. An organic LED (OLED) device is an example of a thin film electro-optic device that can be formed using different techniques including but not limited to shadow masking, photolithography, and printed patterning. Finally, the top electrode 118 of the electro-optic thin film device 112 is deposited and, if needed, patterned. In embodiments where the thickness of the microdevice 106 is significantly high, fractures or other structural problems may occur within the bottom electrode 110. In these embodiments, a planarization layer can be used with or without the dielectric layer 108 to solve this problem. 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 bank structure 114 cover the electrode 116 to avoid any short circuit between the electro-optic device 112 and the device electrode 116.

[0019] Figure 1BIllustrates 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 conditions are engineered such that the contacts 104 define the areas allocated to each pixel. A system substrate 102 with contact pads 104 and a donor substrate with micro - devices 106. After transferring the micro - device 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. After forming the pixel (or sub - pixel) active regions, a color - conversion layer as described can be added to the 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 adjacent pixels (or sub - pixels). In another embodiment, the micro - device 106 is grown on a buffer / sacrificial layer.

[0020] Figure 2A Shows a flat micro - LED panel for a taillight. Figure 2B Shows Figure 2ACross-section of the micro-LED panel along A-A'. Element 202 can be a micro-LED panel that can be composed of one or more patches containing multiple micro-LEDs. Multiple small micro-LED patches can be integrated together into a larger flat panel. The panel can contain micro-LEDs having a density that produces the same light as existing taillights. The panel can use RGB micro-LEDs that may be programmable to display multiple colors. Element 204 can be a substrate to which the micro-LED patches can be bonded. The substrate can be silicon, glass, sapphire, any other substrate known in the art, any material to which the micro-LED patches can be bonded, or any combination of these materials. The substrate can also house or bond to electronic devices connected to the micro-LEDs. These electronic devices can be contained within the substrate, tunnel through the substrate to reach the micro-LEDs, or use the substrate as part of the circuit. Element 206 can be a micro-LED patch composed of multiple micro-LEDs. Element 208 can be an adhesive tape that allows the micro-LED panel to adhere or otherwise connect to the vehicle. Element 210 can be a protective layer. The protective layer can protect against environmental and / or vibration damage. The protective layer can be made of glass, epoxy, plastic, metal, other protective materials, or any combination of protective materials. The protective layer can be an airtight seal. The micro-LED panel can be closer to the exterior of the vehicle compared to a typical taillight bulb, thereby reducing the space required for the taillight. Although the initial cost of the micro-LED taillight may be higher than that of a traditional taillight, cost savings can be achieved in other areas, such as replacement cost and energy cost. The micro-LED is more efficient than a traditional taillight, produces less heat, and wastes less energy. Due to the reduced volume required, the micro-LED taillight can be lighter compared to its traditional counterpart. Due to the small size of the micro-LED panel, the replacement cost of the micro-LED taillight can be lower than that of other taillights, which means that the replacement can be less invasive and simple enough to be completed without the need for vehicle maintenance expertise.

[0021] Figure 3Displays a flat micro-LED panel for a taillight having multiple micro-LED patterns. Element 301 can be a micro-LED panel that can be composed of one or more patches containing multiple micro-LEDs. Multiple small micro-LED patches can be integrated together into a larger flat panel. The panel can contain micro-LEDs having a density that produces the same light as an existing taillight. The panel can use RGB micro-LEDs or blue micro-LEDs with phosphors to obtain white light. Different shaped micro-LED patches can be used to create patterns. When these specific patches are activated, these patterns can be used for the aesthetic effect of the final light projected, organizing the light pattern (such as high beam or low beam), or indicating direction (left or right). Element 302 can be a substrate to which the micro-LED patches can be bonded. The substrate can be silicon, glass, sapphire, any other substrate known in the art, any material to which the micro-LED patches can be bonded, or any combination of these materials. The substrate can also house or be bonded to the electronics connected to the micro-LEDs. These electronics can be contained within the substrate, tunnel through the substrate to reach the micro-LEDs, or use the substrate as part of the circuit. Element 303 can be a first type of micro-LED patch composed of multiple micro-LEDs. For example, these micro-LED patches can act as brake lights and be colored red. Element 304 can be a second type of micro-LED patch composed of multiple micro-LEDs, the second type of micro-LED patch having a different shape, structure, color, or other differentiating factor from the first type of micro-LED patch. For example, these micro-LED patches can be turn signal lights and hazard lights, and can be colored orange and programmed to blink. Element 305 can be a connector that allows Figure 3 the electronics of the micro-LED panel to be connected to the vehicle's electronic system. This can allow the micro-LED panel to be powered and controlled by the vehicle and provide feedback information to the vehicle. The micro-LED panel is closer to the window or lens compared to a typical taillight bulb, thus reducing the space required for the taillight. Although the initial cost of a micro-LED taillight may be higher than that of a traditional taillight, cost savings can be achieved in other aspects, such as replacement cost and energy cost. Additionally, the patterned micro-LED taillight can provide multiple functions and replace more than one light on a vehicle. For example, the micro-LED panel can be used as a taillight and a turn signal light. Micro-LEDs are more efficient than traditional taillights, produce less heat, and waste less energy. Due to the reduced volume required, micro-LED taillights can be lighter compared to their traditional counterparts. Due to the small size of the micro-LED panel, the replacement cost of a micro-LED taillight can be lower than that of other taillights, meaning that the replacement can be less invasive and simple enough to be done without vehicle maintenance expertise.

[0022] Figure 4A Displays a flat micro-LED panel for a taillight. Figure 2B Displays that can include Figure 2AThe structure of a micro-LED panel. Element 401 can be a micro-LED panel that can be composed of one or more patches containing a plurality of micro-LEDs. A plurality of small micro-LED patches can be integrated together into a larger flat panel. The panel can contain micro-LEDs having a density of light generation that is the same as that of existing taillights. The panel can use RGB micro-LEDs. The light intensity from the micro-LED panel can be programmable and can change based on an input. For example, the intensity of the red brake light can be enhanced based on the braking force. A driver applying only a small pressure to the brake can result in a low-intensity but still visible signal light. While a driver braking quickly can result in a high-intensity red light to indicate to the driver behind that a complete stop is imminent. The micro-LED panel can be programmed for visible light communication (VLC) to transmit data from the micro-LED panel to a receiver. The micro-LED can transmit the road conditions or hazards ahead to the vehicle behind, or transmit driving instructions to a tow truck with automatic steering. Element 402 can be a substrate to which the micro-LED patches can be bonded. The substrate can be silicon, glass, sapphire, any other substrate known in the art, any material to which the micro-LED patches can be bonded, or any combination of these materials. The substrate can also house or incorporate electronic devices connected to the micro-LEDs. These electronic devices can be contained within the substrate, tunnel through the substrate to reach the micro-LEDs, or use the substrate as part of a circuit. Element 403 can be a micro-LED patch composed of a plurality of micro-LEDs. Element 404 can be a connector that allows Figure 4A the electronic devices of the micro-LED panel to be connected to the electronic system of a vehicle. This can allow the micro-LED panel to be powered and controlled by the vehicle and provide feedback information to the vehicle. Element 405 can house Figure 4A the structure of the micro-LED panel. The structure can conform to the shape of taillights in existing or upcoming vehicle models such that they can be interchanged with non-micro-LED taillights. Element 406 can be a window that allows light from the micro-LEDs to pass through. The window can include glass, plastic, crystal, transparent or translucent materials, or any combination of these materials. The window can contain lenses or patterns that can diffuse, focus, polarize, block, redirect, or otherwise interact with the light from the micro-LEDs. Element 407 can be Figure 4AA micro-LED panel. Component 408 can be a bracket or base that holds the micro-LED panel in place relative to the vehicle. The bracket or base can also ensure that the electrical connection between the micro-LED panel and the vehicle does not disconnect. The micro-LED panel can be closer to the window compared to a typical taillight bulb, thereby reducing the space required for the taillight. Although the initial cost of the micro-LED taillight may be higher than that of a traditional taillight, cost savings can be achieved in other aspects, such as replacement cost and energy cost. The micro-LED is more efficient than a traditional taillight, generates less heat, and wastes less energy. Due to the reduced volume required, the micro-LED taillight can be lighter compared to its traditional counterpart. Due to the small size of the micro-LED panel, the replacement cost of the micro-LED taillight can be lower than that of other taillights, which means that the replacement can be less invasive and simple enough to be completed without the need for vehicle maintenance expertise.

[0023] Figure 5Shows a micro-LED patch configured by the manufacturer to perform a more intelligent aesthetic rear panel function. Element 501 can be a micro-LED panel composed of one or more patches containing multiple micro-LEDs, and the one or more patches are located on or in the formed glass. The micro-LED patches can be embedded or otherwise integrated into the formed glass. The micro-LED patches can be fixed to a flexible substrate, which is then laminated or otherwise adhered to the formed glass. Multiple small micro-LED patches can be integrated together into a larger flat panel. The panel can contain micro-LEDs with a density that produces the same light as existing taillights. The panel can use RGB micro-LEDs or blue micro-LEDs with phosphors to obtain white light. Element 502 can be a substrate to which a smaller-shaped substrate is bonded. The substrate can be silicon, glass, sapphire, any other substrate known in the art, any material to which other substrates can be bonded, or any combination of these materials. Element 504 can be a formed substrate to which the micro-LED patches can be bonded. Based on the manufacturer's design for optimal aesthetics, the shape of the substrate can indicate a turn or stop or hazard signal (arrow, circle, etc.). One or more of these formed substrate regions can be part of a larger substrate. The substrate can be silicon, glass, sapphire, any other substrate known in the art, any material to which the micro-LED patches can be bonded, or any combination of these materials. The substrate can also house electronics connected to the micro-LEDs or bonded to these electronics. These electronics can be contained within the substrate, tunnel through the substrate to reach the micro-LEDs, or use the substrate as part of a circuit. Element 505 can be a micro-LED patch composed of multiple micro-LEDs. The micro-LED panel can be closer to the window compared to a typical taillight bulb, thus reducing the space required for the taillight. Although the initial cost of a micro-LED taillight may be higher than that of a traditional taillight, cost savings can be achieved in other aspects, such as replacement cost and energy cost. In addition, the formed micro-LED taillight can provide multiple functions and replace more than one light on a vehicle. For example, the micro-LED panel can have multiple formed substrate regions, one serving as a taillight and the other serving as a turn signal light. Micro-LEDs are more efficient than traditional taillights, produce less heat, and waste less energy. Due to the reduced volume required, micro-LED taillights can be lighter than their traditional counterparts. Due to the small size of the micro-LED panel, the replacement cost of micro-LED taillights can be lower than that of other taillights, which means that the invasiveness of replacement can be smaller, and the replacement can be simple enough to be completed without the need for vehicle maintenance expertise.

[0024] Figure 6Disclosed is a flat micro-LED panel for a taillight that shows a micro-LED tile pattern with multiple user selections. Element 601 can be a micro-LED panel that can be composed of one or more tiles containing multiple micro-LEDs. Multiple small micro-LED tiles can be integrated together into a larger flat panel. The panel can contain micro-LEDs having a density that produces the same light as existing taillights. The panel can use RGB micro-LEDs or blue micro-LEDs with phosphors to obtain white light. Different groups of micro-LED tiles can be used to produce patterns. When these specific tiles are activated, these patterns can be used for the aesthetic effect of the projected final light, organizing light patterns (such as high beam or low beam), or indicating direction (left or right). The user can select which micro-LED tiles are part of the pattern. For example, the user can select micro-LED tiles that form an arrow shape, as Figure 6 shown. The user can assign this pattern to indicate a turn signal. The user may be able to fully customize the pattern or select from approved patterns, for example, in cases where there are legal requirements for the appearance of turn signals. The user may be able to customize the brightness and color of the micro-LED tiles. Element 602 can be a substrate to which the micro-LED tiles can be bonded. The substrate can be silicon, glass, sapphire, any other substrate known in the art, any material to which the micro-LED tiles can be bonded, or any combination of these materials. The substrate can also house electronics connected to the micro-LEDs or bonded to these electronics. These electronics can be contained within the substrate, tunnel through the substrate to reach the micro-LEDs, or use the substrate as part of the circuit. Element 604 can be a micro-LED tile composed of multiple micro-LEDs that are not part of the pattern selected by the user. Element 605 can be a micro-LED tile composed of multiple micro-LEDs that are part of the pattern selected by the user. The micro-LED panel can be closer to the window compared to a typical taillight bulb, thus reducing the space required for the taillight. Although the initial cost of a micro-LED taillight may be higher than that of a traditional taillight, cost savings can be achieved in other aspects, such as replacement cost and energy cost. In addition, a patterned micro-LED taillight can provide multiple functions and replace more than one light on a vehicle. For example, the micro-LED panel can be used as a taillight and a turn signal light. Micro-LEDs are more efficient than traditional taillights, produce less heat, and waste less energy. Due to the reduced volume required, micro-LED taillights can be lighter than their traditional counterparts. Due to the small size of the micro-LED panel, the replacement cost of a micro-LED taillight can be lower than that of other taillights, which means that the replacement can be less invasive and simple enough to be completed without the need for vehicle maintenance expertise.

[0025] Figure 7Disclosed is a flat micro-LED panel for a taillight capable of performing visible light communication (VLC). Element 701 may be a micro-LED panel that can be composed of one or more patches containing multiple micro-LEDs. Multiple small micro-LED patches can be integrated together into a larger flat panel. The panel may contain micro-LEDs having a density that produces the same light as existing taillights. The panel may use RGB micro-LEDs. The light intensity from the micro-LED panel can be programmable and changed based on an input. For example, the intensity of the red brake light can be enhanced based on the braking force. A driver applying only a small pressure to the brake can result in a low-intensity but still visible signal light. While a driver braking quickly can result in a high-intensity red light to indicate to the driver behind an impending full stop. The micro-LED panel can be programmed for visible light communication (VLC), so data can be transmitted from the micro-LED panel to a receiver. The micro-LEDs can transmit the road conditions or hazards ahead to the vehicle behind, or transmit driving instructions to a tow truck with automatic steering. Element 702 may be a substrate to which the micro-LED patches can be bonded. The substrate can be silicon, glass, sapphire, any other substrate known in the art, any material to which the micro-LED patches can be bonded, or any combination of these materials. The substrate can also house electronics connected to the micro-LEDs or bonded to these electronics. These electronics can be contained within the substrate, tunnel through the substrate to reach the micro-LEDs, or use the substrate as part of the circuit. Element 703 may be a connector that allows the micro-LED electronics to connect to a bus. Element 704 may be a micro-LED patch composed of multiple micro-LEDs. Element 705 may be a bus that allows the electronics of the micro-LED panel to receive instructions from a VLC controller. Element 706 may be a VLC controller that instructs some or all of the micro-LED patches to modulate the intensity of the emitted light to encode data. Then, the data can be received by a photodetector that converts the light back into an electrical signal that can be processed by a computer or other device. The photodetector can be in the vehicle behind or on a trailer towed by the vehicle to which the micro-LED panel is attached. The micro-LEDs can transmit the road conditions or hazards ahead to the vehicle behind, or transmit driving instructions to a tow truck with automatic steering. The micro-LED panel can be closer to the window compared to a typical taillight bulb, thus reducing the space required for the taillight. Although the initial cost of the micro-LED taillight may be higher than that of a traditional taillight, cost savings can be achieved in other aspects, such as replacement cost and energy cost. The additional benefits of VLC may be worth the premium, such as savings in the cost that would be spent on wiring that would normally connect the vehicle to the tow truck. If taillights supporting VLC are proven to reduce collisions or other accidents, insurance companies may incentivize taillights supporting VLC. Micro-LEDs are more efficient than traditional taillights, produce less heat, and waste less energy. Due to the reduced volume required, micro-LED taillights can be lighter compared to their traditional counterparts.Due to the small size of the micro-LED panel, the replacement cost of the micro-LED taillight can be lower than that of other taillights, which means that the replacement can be less invasive and simple enough to be completed without the need for vehicle maintenance expertise.

[0026] Figure 8Shows a micro-LED panel embedded in a reflector within a taillight to enhance direction and intensity. Element 801 can be three micro-LED panels embedded in the reflector. Each micro-LED panel can be a different signal, such as stop, turn, or hazard. Element 802 can be a reflector made of a highly reflective material such as metal or glass. The most common type of reflector is a mirror made of a metal sheet or glass sheet coated with a thin layer of a highly reflective material (such as aluminum or silver). Other materials commonly used in reflectors include plastics, ceramics, and various metal alloys. The specific material used in the reflector will depend on the intended application and the desired level of reflectivity. Element 803 can be a micro-LED panel that can be composed of one or more patches containing multiple micro-LEDs. Multiple small micro-LED patches can be integrated together into a larger flat panel. The panel can contain micro-LEDs having a density that produces the same light as an existing taillight. The panel can use RGB micro-LEDs. The light intensity from the micro-LED panel can be programmable and changed based on an input. For example, the intensity of a red brake light can be enhanced based on the braking force. A driver applying only a small pressure to the brake can result in a low-intensity but still visible signal light. While a driver braking quickly can result in a high-intensity red light to indicate to the driver behind that a full stop is imminent. Element 804 can be a substrate to which the micro-LED patches can be bonded. The substrate can be silicon, glass, sapphire, any other substrate known in the art, any material to which the micro-LED patches can be bonded, or any combination of these materials. The substrate can also house electronics connected to the micro-LEDs or bonded to these electronics. These electronics can be contained within the substrate, tunnel through the substrate to reach the micro-LEDs, or use the substrate as part of a circuit. Element 805 can be a directional area. The reflector and micro-LED panel in this area can indicate that the vehicle is turning. Element 806 can be a stop area. The reflector and micro-LED panel in this area can indicate that the vehicle is braking. Element 807 can be a hazard area. The reflector and micro-LED panel in this area can indicate that the driver of the vehicle has turned on the hazard signal. The micro-LED panel can be closer to the window compared to a typical taillight bulb, thereby reducing the space required for the taillight. While the initial cost of a micro-LED taillight may be higher than that of a traditional taillight, cost savings can be achieved in other aspects, such as replacement cost and energy cost. In addition, the areas of the micro-LED taillight can each replace one or more lights on the vehicle. For example, the micro-LED panel can act as a brake light, hazard light, and turn signal light. Micro-LEDs are more efficient than traditional taillights, produce less heat, and waste less energy. Due to the reduced volume required, the micro-LED taillight can be lighter compared to its traditional counterpart. Due to the small size of the micro-LED panel, the replacement cost of the micro-LED taillight can be lower than that of other taillights, which means that the replacement can be less invasive and simple enough to be completed without the need for vehicle maintenance expertise. The protective seal can reduce the rate at which the micro-LED taillight needs to be replaced compared to traditional taillights.
