[0014] 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 example embodiments are shown in the drawings. However, the embodiments of the claims may be implemented 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 invention relates to a structure, system, and method in which multiple sensors collect data for intelligent lighting and illumination aspects of vehicle lighting as needed.
[0015] Figure 1AAn example of integrating the transferred 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 mosaic module, which is later picked and placed into a mosaic module array. For those skilled in the art, it is obvious that there are many ways to form micro-LED mosaic modules and integrate them into a mosaic module array, as described in US20160218143A1, "Microdevice integration into system substrate". In many hybrid structure embodiments, a receiver substrate 102 and contact pads 104 are provided, onto which an array of microdevices 106 is transferred and the thin-film electro-optic device is integrated. The microdevice 106 can be transferred and bonded to the bonding pads 104 of the receiving 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. If there is no risk of unwanted coupling between the bottom electrode 110 and other conductive layers in the receiving substrate, the dielectric layer 108 can be eliminated. However, this dielectric layer can also be used as a planarization layer to provide better manufacturing conditions for the electro-optic device 112. A barrier layer 114 is deposited on 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. Organic LED (OLED) devices are an example of thin-film electro-optic devices, and they can be formed using different techniques, such as but not limited to shadow mask, lithography, and printing patterning. Finally, the top electrode 118 of the electro-optic thin-film device 112 is deposited and patterned if necessary. In embodiments where the thickness of the microdevice 106 is significantly increased, cracks or other structural problems may occur in the bottom electrode 110. In these embodiments, a planarization layer can be used in combination 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 shared among other microdevices 106 in the system substrate. In this case, the planarization layer (if present) and / or the barrier structure 114 cover the electrode 116 to avoid any short circuit between the electro-optic device 112 and the device electrode 116.
[0016] Figure 1BShows the structure of sharing the device among several pixels (or sub - pixels) after post - processing to deposit the common electrode and 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 assigned 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 can be performed, such as depositing the common electrode 120, color conversion layer 122, filter, etc. However, the methods described in this disclosure and other possible methods can be used. After forming the pixel (or sub - pixel) active area, the described color conversion layer can be added to this active area. If the active area of the pixel (or sub - pixel) is covered by a reflective layer, the addition of this layer can provide a higher fill factor and better performance, and avoid color leakage from the edge pixels (or sub - pixels). In another embodiment, the micro - device 106 is grown on a buffer / sacrificial layer.
[0017] Figure 2 shows an embodiment of using micro - LEDs in a headlight to enhance road signs. Figure 2AShows multiple road signs that can be enhanced by using micro LEDs in the headlight. Road sign 201 can be a traffic sign or a guide sign erected beside or above the road, used to give instructions or provide information to road users. Road sign 201 can be a regulatory sign used to indicate or enforce traffic laws, regulations, or requirements applicable at all times or at specific times or locations on a street or highway, and ignoring these laws, regulations, or requirements may constitute an illegal act, or it can be a general sign used to regulate the public behavior in places open to the public. Road sign 201 can be a warning sign, which is a sign indicating potential hazards, obstacles, or situations that require special attention. Some traffic signs indicate road hazards that drivers may not easily notice. Road sign 201 can be reflected by glass beads, micro prisms, or encapsulated lenses that may be present on the reflective sheet. These materials bend the light and return it to the light source, so that the driver can clearly see the guide sign when turning on the headlight at night. The orange-and-black 202 road sign 201 can be detected by the rotary color module 220 and displayed to the driver with the orange light generated by the micro LED panel 210 to enhance the visual effect of the orange-and-black 202 road sign 201. In some embodiments, the light generated by the micro LED panel 220 can be white light to reflect the orange-and-black sign back into the driver's field of vision. In some embodiments, the orange-and-black 202 road sign 201 can include glass beads, micro prisms, or encapsulated lenses on the reflective sheet to bend the light and return it to the high-visibility light source. The dark orange-and-black 204 road sign 201 can be detected by the rotary color module 220 and displayed to the driver with the dark orange light generated by the micro LED panel 210 to enhance the visual effect of the dark orange-and-black 204 road sign 201. In some embodiments, the light generated by the micro LED panel 220 can be white light to reflect the dark orange-and-black sign back into the driver's field of vision. In some embodiments, the dark orange-and-black 204 road sign 201 can include glass beads, micro prisms, or encapsulated lenses on the reflective sheet to bend the light and return it to the high-visibility light source. The orange-red-black 206 road sign 201 can be detected by the rotary color module 220 and displayed to the driver with the orange-red light generated by the micro LED panel 210 to enhance the visual effect of the orange-red-black 206 road sign 201. In some embodiments, the light generated by the micro LED panel 220 can be white light to reflect the orange-red-black sign back into the driver's field of vision. In some embodiments, the orange-red-black 206 road sign 201 includes glass beads, micro prisms, or encapsulated lenses on the reflective sheet to bend the light and return it to the high-visibility light source. The black-and-white 208 road sign 201 can be detected by the rotary color module 220 and displayed to the driver with the white light generated by the micro LED panel 210 to enhance the visual effect of the black-and-white 208 road sign 201.In some embodiments, the light generated by the micro-LED panel 220 can be multiple light colors, such as red, blue, green, etc., to reflect the black-and-white sign back into the driver's field of view. In some embodiments, the black-and-white 208 road sign 201 may include glass beads, microprisms, or encapsulated lenses on the reflective sheet to bend the light back to the high-visibility light source. Figure 2B An embodiment of the micro-LED panel 210 is shown, which generates multiple colors to illuminate the road sign 201. The micro-LED panel 210 can be composed of one or more tiled modules containing multiple micro-LEDs. Multiple micro-LED small tiled modules can be integrated together into a larger flat panel. The micro-LED panel 210 may include a substrate 212, micro-LED units 214, and multiple connectors 216. The micro-LED panel 210 allows the micro-LED units 214 to generate a visual effect for the driver to act as a headlight or replace the existing headlight of the vehicle, such as illuminating the driver's driving path when the driver is driving at night or in dark conditions. In some embodiments, the micro-LED units 214 can be connected, bonded, adhered, etc. to the vehicle's headlight to generate light or illuminate the vehicle's driving path. The substrate 212 can be made of glass, silicon, plastic, or any other commonly used material. The substrate 212 can also have active electronic components, such as but not limited to transistors, resistors, capacitors, or any other electronic components commonly used in a system substrate. In some cases, the substrate 212 can be a substrate 212 with electrical signal rows and columns. In one example, the substrate 212 can be a sapphire substrate with an LED layer grown monolithically on its top, and the substrate 212 can be a backplane with a circuit system for deriving micro-LED devices. In some embodiments, the substrate 212 can be a flexible or rigid substrate 212. The micro-LED units 214 contain multiple micro-LED (light-emitting diode) arrays, where each micro-LED serves as a pixel and can be driven to emit light. The micro-LED is composed of multiple micro-LEDs, and each display pixel emits light by itself. The micro-LED is a modular technology. For example, the panel is composed of a series of tiny red, green, and blue LEDs and is connected together to form a larger whole. In some embodiments, micro-LED units 214 of various sizes can be produced to increase the width or length of the micro-LED units 214. The connectors 216 can be electrochemical devices for establishing electrical connections between multiple micro-LED tiled modules, thereby forming the micro-LED units 214. The connectors 216 can receive power, data signals, information instructions, etc. from a ribbon connector to power and control each micro-LED in the micro-LED tiled modules that make up the micro-LED units 214. Figure 2CShows the components of a micro-LED headlight that produce multiple colors to illuminate road sign 201. These components may include a memory 218, a rotary color module 220, a processor 224, a bus controller 226, and a micro-LED panel 228. The memory 218 may include, but is not limited to, fixed (hard) drives, magnetic tapes, floppy disks, optical disks, compact disc read-only memory (CD-ROM), magneto-optical disks, semiconductor memories (such as ROM, random access memory (RAM), programmable read-only memory (PROM), erasable PROM (EPROM), electrically erasable PROM (EEPROM), flash memory), magnetic memory cards or optical memory cards, or another type of medium / machine-readable medium suitable for storing electronic instructions. The memory 218 may include modules implemented as programs. The rotary color module 220 may include executable programs to generate appropriate lighting conditions to illuminate road sign 201 using the micro-LED panel 228 by collecting data from multiple sensors (such as charge-coupled device (CCD) cameras, multispectral cameras, lasers, infrared sensors, radar sensors, etc.), which employ downstream processing to identify road sign 201 in or ahead of the vehicle's travel path. In some embodiments, the rotary color module 220 may use image recognition to identify road sign 201. The rotary color module 220 continuously receives data from the sensors and determines whether the object is road sign 201. If it is determined that the object is road sign 201, the rotary color module compares road sign 201 with a rules database. The rules database may contain multiple road signs 201 and corresponding executable programs, which will be sent to the bus controller 226, which sends signals to the micro-LED panel 228 to produce specific light to illuminate road sign 201. The rotary color module 220 extracts the corresponding rules or executable programs. It executes the program by sending appropriate signals to the bus controller 226 to illuminate the micro-LED panel 228 in appropriate lighting. For example, if the orange and black striped 202 road sign 201 is recognized, the extracted rule will be that the micro-LED panel 228 produces orange light to illuminate road sign 201. The processor 224 may be configured to decode and execute any instructions received from one or more other electronic devices or servers. The processor 224 may include one or more general-purpose processors (e.g., or Advanced Micro Microprocessors) and / or one or more dedicated processors (e.g., digital signal processors or System-on-Chip (SOC) Field Programmable Gate Array (FPGA) processor). The processor 224 can be configured to execute one or more computer-readable program instructions (such as program instructions) to perform any function described in this specification. The bus controller 226 can be a computer bus used by the vehicle CPU to communicate with devices contained within a computer via a physical connection such as a cable or printed circuit. The vehicle CPU sends various control signals to components and devices to send control signals to the CPU using the control bus. One of the main purposes of the bus is to minimize the number of lines required for communication. The bus controller 226 can be bidirectional and helps the CPU synchronize control signals to internal devices and external components. It includes interrupt lines, byte enable lines, read / write signals, and status lines. The road sign 201 can be enhanced using the micro-LED panel 228 through the rotary color module 220. The rotary color module 220 first continuously polls to receive sensor data from a sensor. For example, the sensor can be a Charge-Coupled Device (CCD) camera, a multispectral camera, a laser, an infrared sensor, a radar sensor, etc., which employ downstream processing to identify the road sign 201 in or ahead of the vehicle's driving path. In some embodiments, the rotary color module 220 can use image recognition to identify the road sign 201. The rotary color module 220 receives sensor data from a sensor. For example, the sensor can be a Charge-Coupled Device (CCD) camera, a multispectral camera, a laser, an infrared sensor, a radar sensor, etc., which employ downstream processing to identify the road sign 201 in or ahead of the vehicle's driving path. In some embodiments, the rotary color module 220 can use image recognition to identify the road sign 201. The rotary color module 220 determines whether an object exists based on the collected sensor data. For example, if an object is identified through the sensor data, the rotary color module can determine whether the object is the road sign 201. If it is determined that no object exists, the process returns to collecting sensor data. The rotary color module 220 determines whether the object is the road sign 201. For example, the rotary color module 220 can compare the identified object with a road sign database containing various shapes, colors, etc. of the road sign 201 to allow the rotary color module 220 to identify the object as a road sign by the shape of the object. If the object is a road sign, the rotary color module 220 compares the road sign 201 with a rule database. The rule database can contain multiple road signs 201 and corresponding rules or executable programs, which will be sent to the bus controller 226, and the bus controller will send signals to the micro-LED panel 228 to generate specific light to illuminate the road sign 201. For example, if the identified road sign 201 is an orange and black 202 road sign 201, the corresponding rule or executable program can be that the micro-LED panel 228 generates orange light to enhance the visual effect of the orange and black 202 road sign 201.For example, since the road sign 201 is orange and black 202, the orange light generated by the micro LED panel 228 reflects the orange color of the road sign 201 back, and the black part of the road sign 201 will be absorbed by the road sign 201, thereby displaying the road sign 201 as a bright orange and black 202 road sign 201. In some embodiments, the light generated by the micro LED panel 228 can be a slightly modified light that contains more wavelengths of the color of the detected road sign 201. For example, the light is composed of various wavelengths, and each wavelength represents a specific color. For example, if the road sign 201 is orange and black 202, the light generated by the micro LED panel can be white, such as containing all wavelengths and having additional wavelengths that produce orange. In some embodiments, the corresponding wavelengths can be intermittently flashed or blinked, and the white headlight effect can still be seen by the naked eye, but due to the use of multiple corresponding wavelengths that better match the color of the road sign 201, a brighter sign visual effect can be provided to the driver. The rotating color module 220 extracts the corresponding rules from the rule database. For example, the rule database may contain a plurality of road signs 201 and a corresponding executable program that will be sent to the bus controller 226, which sends a signal to the micro LED panel 228 to generate a specific light to illuminate the road sign 201. The rotating color module 220 executes the rules extracted from the rule database. For example, the rotating color module 220 extracts the corresponding rule or executable program. It executes the program by sending an appropriate signal to the bus controller 226 to illuminate the micro LED panel 228 in the appropriate lighting, such as if an orange and black 202 road sign 201 is identified, the extracted rule would be for the micro LED panel 228 to generate orange light to illuminate the road sign 201.

Sign 301 can be a traffic sign or a guide sign, which are signs erected beside or above the road to give instructions or provide information to road users. Sign 301 can serve as an information source sign or have an informing function. Sign 301 can be a direction sign, more comprehensively defined as a direction, position or indication sign, such as any guide sign mainly used to provide information about the position of the driver or a possible destination, and is considered a subset of the group of indication signs. Guide sign 302, which can be a sign 301, can be a traffic sign or a guide sign erected beside or above the road to give instructions or provide information to road users. Guide sign 302 can serve as an information source sign or have an informing function. Guide sign 302 can be a direction sign, more comprehensively defined as a direction, position or indication sign, such as any guide sign mainly used to provide information about the position of the driver or a possible destination, and is considered a subset of the group of indication signs. Region 1304 can be part of guide sign 302, indicating the direction of towns, cities, villages, counties, states, roads, routes, highways, etc. In some embodiments, region 1 304 can provide the direction, position, information or indication of a specific location or destination. Region 2 306 can be part of guide sign 302, indicating the direction of towns, cities, villages, counties, states, roads, routes, highways, etc. In some embodiments, region 2 306 can provide the direction, position, information or indication of a specific location or destination. Region 3 308 can be part of guide sign 302, indicating the direction of towns, cities, villages, counties, states, roads, routes, highways, etc. In some embodiments, region 3 308 can provide the direction, position, information or indication of a specific location or destination. Figure 3BShows the components of a micro-LED headlamp that produce multiple colors to illuminate sign 301.

The rule database may contain multiple signs 301 and corresponding rules or executable programs, and the rule or executable program will be sent to the bus controller 326, which sends a signal to the micro-LED panel 328 to generate specific light to illuminate the sign 301. For example, if the identified sign 301 is a directional sign 301, the corresponding rule or executable program may be that the micro-LED panel 328 generates green light to enhance the visual effect of the green sign 301. For example, since the sign 301 is green, the green light generated by the micro-LED panel 328 reflects the green of the sign 301, and the white part of the sign 301 will be reflected by the sign 301, thus displaying the sign 301 as a bright green and white sign 301. In some embodiments, the light generated by the micro-LED panel 328 may be slightly modified light that contains more wavelengths of the color of the detected sign 301. For example, light consists of various wavelengths, and each wavelength represents a specific color. For example, if the sign 301 is green and white, the light generated by the micro-LED panel may be white, such as containing all wavelengths, and also having additional wavelengths that produce green. In some embodiments, the corresponding wavelengths can be made to flash intermittently or blink, still presenting a white headlight effect to the naked eye, but providing a brighter sign visual effect for the driver due to the use of multiple corresponding wavelengths that better match the color of the sign 301. The rotary color module 320 extracts the corresponding rule from the rule database. For example, the rule database may contain multiple signs 301 and corresponding executable programs, and the executable program will be sent to the bus controller 326, which sends a signal to the micro-LED panel 328 to generate specific light to illuminate the sign 301. The rotary color module 320 executes the rule extracted from the rule database. For example, the rotary color module 320 extracts the corresponding rule or executable program. It executes the program by sending an appropriate signal to the bus controller 326 to illuminate the micro-LED panel 328 in appropriate lighting. For example, if a green and white sign 301 is identified, the extracted rule will be that the micro-LED panel 328 generates green light to illuminate the sign 301.

The micro-LED panel 410 can be composed of one or more tiled modules that contain multiple micro-LEDs. Multiple micro-LED small tiled modules can be integrated together into a larger flat panel. The micro-LED panel 410 can include a substrate 412, micro-LED units 414, and multiple connectors 416. The micro-LED panel 410 allows the micro-LED units 414 to produce a visual effect for the driver to act as a headlight or replace an existing headlight of a vehicle, such as illuminating the driver's driving path when the driver is driving at night or in dark conditions. In some embodiments, the micro-LED units 414 can be connected, bonded, adhered, etc. to the vehicle's headlight to produce light or illuminate the vehicle's driving path.

The memory 418 may include modules implemented as programs. The rotary color module 420 may include executable programs to generate appropriate lighting conditions to illuminate the road reflector 401 using the micro-LED panel 428 by collecting data from multiple sensors (such as charge-coupled device (CCD) cameras, multispectral cameras, lasers, infrared sensors, radar sensors, etc.), which employ downstream processing to identify the road reflector 401 in or ahead of the vehicle's travel path. In some embodiments, the rotary color module 420 may use image recognition to identify the road reflector 401. The rotary color module 420 continuously receives data from the sensors and determines whether the object is the road reflector 401. If it is determined that the object is the road reflector 401, the rotary color module compares the road reflector 401 with a rule database. The rule database may contain multiple road reflectors 401 and corresponding executable programs, which will be sent to the bus controller 426, which sends signals to the micro-LED panel 428 to produce specific light to illuminate the road reflector 401. The rotary color module 420 extracts the corresponding rule or executable program and executes the program by sending appropriate signals to the bus controller 426 to illuminate the micro-LED panel 428 under appropriate lighting. The processor 424 may be configured to decode and execute any instructions received from one or more electronic devices or servers. The processor 424 may include one or more general-purpose processors (e.g., or Advanced Micro (AMD) microprocessors) and / or one or more dedicated processors (e.g., digital signal processors or System-on-Chip (SOC) Field Programmable Gate Array (FPGA) processor). The processor 424 can be configured to execute one or more computer-readable program instructions (such as program instructions) to perform any function described in this specification. The bus controller 426 can be a computer bus used by the vehicle CPU to communicate with devices within a computer through a physical connection such as a cable or printed circuit. The vehicle CPU sends various control signals to components and devices to send control signals to the CPU using the control bus. One of the main purposes of the bus is to minimize the number of lines required for communication. The bus controller 426 can be bidirectional and helps the CPU synchronize control signals to internal devices and external components. It includes interrupt lines, byte enable lines, read / write signals, and status lines. The micro-LED unit 428 contains multiple arrays of micro-LEDs (light-emitting diodes), where each micro-LED serves as a pixel and can be driven to emit light. The micro-LED consists of multiple micro-LEDs, and each display pixel emits light by itself. Micro-LED is a modular technology.

For example, the sensors can be charge-coupled device (CCD) cameras, multispectral cameras, lasers, infrared sensors, radar sensors, etc., which use downstream processing to identify the road reflector 401 in or ahead of the vehicle's driving path. In some embodiments, the rotary color module 420 can use image recognition to identify the road reflector 401. The rotary color module 420 determines whether an object exists based on the collected sensor data. For example, if an object is identified through the sensor data, the rotary color module can determine whether the object is the road reflector 401. If it is determined that no object exists, the process returns to collecting sensor data. The rotary color module 420 determines whether the object is the road reflector 401. For example, the rotary color module 420 can compare the identified object with a sign database containing various shapes, colors, etc. of the road reflector 401 to allow the rotary color module 420 to identify the object as the road reflector 401 by the shape of the object.If the object is the road reflector 401, the rotary color module 420 compares the road reflector 401 with the rule database. The rule database may contain multiple road reflectors 401 and corresponding rules or executable programs, and the rule or executable program will be sent to the bus controller 426, which will send a signal to the micro-LED panel 428 to generate specific light to illuminate the road reflector 401. For example, if the identified road reflector 401 is a lane reflector 401, the corresponding rule or executable program may be that the micro-LED panel 428 generates yellow light to enhance the visual effect of the yellow road reflector 401. For example, since the road reflector 401 is yellow, the yellow light generated by the micro-LED panel 428 reflects the yellow of the road reflector 401, and the white part of the road reflector 401 will be reflected by the road reflector 401, thus displaying the road reflector 401 as a bright yellow road reflector 401.

For example, the panel consists of a series of tiny red, green, and blue LEDs and is connected together to form a larger whole. In some embodiments, micro-LED units 514 of various sizes can be produced to increase the width or length of micro-LED unit 514. Multispectral camera 516 can capture image data within a specific wavelength range of the electromagnetic spectrum. These wavelengths can be separated by filters or detected using instruments sensitive to specific wavelengths, including light from frequencies outside the visible light range, namely infrared and ultraviolet. Optical system 518 can be a black ice detector system that differentiates water, ice, and the differences between them on the road surface by measuring the radiance of several spectral bands. These measurements can be made using a photodetector, thermopile, and camera with bandpass filters of appropriate wavelengths. Optical system 518 can detect slippery road conditions on roads and bridges. The detection of black ice can immediately alert the driver when a slippery road condition is encountered on the road, bridge, and parking lot in front of the vehicle. For example, optical system 518 can be a system for detecting ice or large supercooled droplets in the region of interest, with a detection system that measures the emissivity or reflectivity of the region of interest when exposed to short-wave infrared radiation within the wavelength range of approximately 2.05 μm to approximately 2.30 μm. The detection system measures the emissivity or reflectivity of a first band within the wavelength range of approximately 2.05 μm to approximately 2.15 μm and outputs a first band signal, and also measures the emissivity or reflectivity of a second band within the wavelength range of approximately 2.15 μm to approximately 2.30 μm and outputs a second band signal. The processing unit determines the ratio of the first band signal and the second band signal, compares this ratio with a pre-determined critical ratio, and outputs a determination signal indicating the presence of ice or supercooled water droplets. The integrated black ice detector 510 can enhance the detection of black ice by using micro-LED panel 514 through the black ice module. The black ice module first continuously polls to receive sensor data from the sensors.For example, the sensor can be an optical system 518, a multispectral camera 516, a charge-coupled device (CCD) camera, a laser, an infrared sensor, a radar sensor, etc., which use downstream processing to identify black ice in or ahead of the vehicle's driving path.

In some embodiments, the black ice detector 510 can include a temperature sensor 520 that can detect and measure temperature changes in the environment. The temperature sensor 520 can include a temperature-sensitive material that changes its resistance in response to temperature changes, such as a thermistor. The temperature sensor 520 can also include a temperature-related voltage generator that generates a voltage proportional to the temperature. The temperature sensor 520 can be connected to a microcontroller or other processing unit that receives the output of the sensor and converts it into a digital signal. The microcontroller can also be programmed to perform various temperature-related functions, such as temperature compensation, temperature monitoring, or temperature control.Data collected by temperature sensor 520 can be used by black ice detector 510 to determine the presence of black ice. In some embodiments, the rules database can contain rules corresponding to data collected by optical system 518 and temperature sensor 520 to warn the driver of the presence of black ice on the road.

Figure 6AShows an embodiment of a micro-LED panel 601 that produces multiple colors to illuminate a road and adjusts the light emission intensity based on oncoming traffic. The micro-LED panel 601 can be composed of one or more tiled modules containing multiple micro-LEDs. Multiple micro-LED small tiled modules can be integrated together into a larger flat panel. The micro-LED panel 601 can include a substrate 602, micro-LED units 604, and multiple connectors 606. The micro-LED panel 601 allows the micro-LED units 604 to produce a visual effect for the driver to act as a headlight or replace the existing headlight of the vehicle, such as illuminating the driver's driving path when the driver is driving at night or in dark conditions. In some embodiments, the micro-LED units 604 can be connected, bonded, adhered, etc. to the vehicle's headlight to produce light or illuminate the vehicle's driving path. The substrate 602 can be made of glass, silicon, plastic, or any other common material.

The connectors 606 can be electrochemical devices for establishing electrical connections between multiple micro-LED tiled modules, thus forming the micro-LED units 604. The connectors 606 can receive power, data signals, information instructions, etc. from a ribbon connector to power and control each micro-LED in the micro-LED tiled modules that make up the micro-LED units 604. Figure 6BShows an implementation of components of an oncoming traffic detector and system, such components as substrate 612, micro-LED panel 614, multispectral camera 616, and oncoming traffic controller 618. The substrate 612 can be made of glass, silicon, plastic, or any other common material. The substrate 612 can also have active electronic components, such as but not limited to transistors, resistors, capacitors, or any other electronic components commonly used in system substrates. In some cases, the substrate 612 can be a substrate 612 with electrical signal rows and columns. In one example, the substrate 612 can be a sapphire substrate on which an LED layer is monolithically grown on top, and the substrate 612 can be a backplane having circuitry for deriving micro-LED devices. In some implementations, the substrate 612 can be a flexible or rigid substrate 612. The micro-LED unit 614 contains multiple arrays of micro-LEDs (light-emitting diodes), where each micro-LED serves as a pixel and can be driven to emit light. The micro-LEDs consist of multiple micro-LEDs, and each display pixel emits light by itself. Micro-LED is a modular technology. For example, the panel consists of a series of tiny red, green, and blue LEDs and is connected together to form a larger whole. In some implementations, micro-LED units 614 of various sizes can be produced to increase the width or length of the micro-LED unit 614. The multispectral camera 616 can capture image data within a specific wavelength range of the electromagnetic spectrum. These wavelengths can be separated by filters or detected using instruments sensitive to specific wavelengths, including light from frequencies outside the visible light range, namely infrared and ultraviolet. The oncoming traffic controller 618 can detect oncoming traffic with the help of cameras, especially CCD cameras with downstream image processing software, and / or laser sensors, infrared sensors, and / or radar sensors. These sensors detect whether there are other vehicles on the road, such as whether they are approaching or located in front of the detecting vehicle. A charge-coupled device (CCD) is a photosensitive integrated circuit that captures images by converting photons into electrons. The CCD sensor decomposes the image elements into pixels. Each pixel is converted into a charge, and the intensity of the charge is related to the intensity of the light captured by that pixel. The integrated oncoming traffic detector 610 can adjust the light emission intensity of the micro-LED panel 614 through a traffic control module. The traffic control module first continuously polls to receive sensor data from the sensors. For example, the sensors can be the oncoming traffic controller 618, camera 616, charge-coupled device (CCD) lasers, infrared sensors, radar sensors, etc., which use downstream processing to identify black ice in or ahead of the vehicle's driving path. The traffic control module receives sensor data from the sensors. For example, the sensors can be the oncoming traffic controller 618, camera 616, charge-coupled device (CCD) lasers, infrared sensors, radar sensors, etc., which use downstream processing to identify black ice in or ahead of the vehicle's driving path. The traffic control module determines whether there is a vehicle approaching the vehicle itself.For example, the oncoming traffic controller 618 can detect oncoming traffic by means of a camera, in particular a CCD camera with downstream image processing software, and / or a laser sensor, an infrared sensor, and / or a radar sensor. These sensors detect whether there are other vehicles on the road, such as whether they are approaching or in front of the detected vehicle. A charge-coupled device (CCD) is a photosensitive integrated circuit that captures images by converting photons into electrons. The CCD sensor decomposes the image elements into pixels. Each pixel is converted into an electric charge, and the intensity of the charge is related to the intensity of the light captured by the pixel. If the oncoming traffic controller 618 detects oncoming traffic, the traffic control module extracts the corresponding rule from the rule database. For example, the corresponding rule can be to adjust the madness of the light generated by the micro-LED panel 614, such as turning off the high beam, dimming the headlights, etc. In some embodiments, the traffic control module and the black ice module can operate continuously to assist the driver. In some embodiments, the rotary color module can operate continuously to detect and adjust the light generated by the micro-LED panel 614 for road signs, identification plates, and road reflectors. For example, the rotary color module first continuously polls to receive sensor data from the sensors. For example, the sensors can be an optical system, an oncoming traffic controller, a charge-coupled device (CCD) camera, a multispectral camera, a laser, an infrared sensor, a radar sensor, etc., which use downstream processing to identify road signs, identification plates, road reflectors, black ice, and oncoming traffic in or in front of the vehicle's driving path. In some embodiments, the rotary color module can use image recognition to identify road signs, identification plates, road reflectors, black ice, and oncoming traffic. The rotary color module receives sensor data from the sensors. For example, the sensors can be an optical system, an oncoming traffic controller, a charge-coupled device (CCD) camera, a multispectral camera, a laser, an infrared sensor, a radar sensor, etc., which use downstream processing to identify road signs, identification plates, road reflectors, black ice, and oncoming traffic in or in front of the vehicle's driving path. In some embodiments, the rotary color module can use image recognition to identify road signs, identification plates, road reflectors, black ice, and oncoming traffic. The rotary color module determines whether there is an object based on the collected sensor data. For example, if an object is identified through the sensor data, the rotary color module can determine whether the object is a road sign, an identification plate, a road reflector, black ice, and oncoming traffic. If it is determined that there is no object, the process returns to collecting sensor data. The rotary color module determines whether the object is a road sign, an identification plate, a road reflector, black ice, and oncoming traffic. For example, the rotary color module can compare the identified object with a database containing various shapes, colors, etc. of road signs, identification plates, road reflectors, black ice, and oncoming traffic to allow the rotary color module to identify the object as a road sign, an identification plate, a road reflector, black ice, and oncoming traffic by the shape of the object.If the objects are road signs, identification plates, road reflectors, black ice, and oncoming traffic, the rotary color module compares the road signs, identification plates, road reflectors, black ice, and oncoming traffic with the rule database. The rule database may contain multiple road signs, identification plates, road reflectors, etc., as well as corresponding rules or executable programs, and the rule or executable program will be sent to the bus controller, which will send a signal to the micro-LED panel 228 to generate specific light to illuminate the road signs, identification plates, road reflectors, making it easier to detect black ice or reducing the light emission intensity of the lights for oncoming traffic. For example, if the identified road sign is an orange-and-black road sign, the corresponding rule or executable program can be that the micro-LED panel generates orange light to enhance the visual effect of the orange-and-black road sign. For example, since the road sign is orange-and-black, the orange light generated by the micro-LED panel reflects the orange of the road sign, and the black part of the road sign will be absorbed by the road sign, thus displaying the road sign as a bright orange-and-black road sign. For example, if the identified identification plate is a direction identification plate, the corresponding rule or executable program can be that the micro-LED panel generates green light to enhance the visual effect of the green identification plate. For example, since the identification plate is green, the green light generated by the micro-LED panel reflects the green of the identification plate, and the white part of the identification plate will be reflected by the identification plate, thus displaying the identification plate as a bright green-and-white identification plate. For example, if the identified road reflector is a lane reflector, the corresponding rule or executable program can be that the micro-LED panel generates yellow light to enhance the visual effect of the yellow road reflector. For example, since the road reflector is yellow, the yellow light generated by the micro-LED panel reflects the yellow of the road reflector, and the white part of the road reflector will be reflected by the road reflector, thus displaying the road reflector as a bright yellow road reflector. In some embodiments, the light generated by the micro-LED panel can be slightly modified light that contains more wavelengths of the color of the detected road sign, identification plate, or road reflector. For example, light is composed of various wavelengths, and each wavelength represents a specific color. For example, if the road sign is orange-and-black, the light generated by the micro-LED panel can be white, such as containing all wavelengths and also having additional wavelengths that produce orange. In some embodiments, the corresponding wavelengths can be made to flash intermittently or blink, still presenting a white headlight effect to the naked eye, but providing a brighter identification visual effect for the driver due to the use of multiple corresponding wavelengths that match the color of the road sign, identification plate, or road reflector more closely. The rotary color module extracts the corresponding rules from the rule database.For example, the rules database may include multiple road signs, identification plates, road reflectors, black ice, and oncoming traffic, as well as corresponding executable programs that will be sent to the bus controller, which will send signals to the micro-LED panel to generate specific light to illuminate the road signs, identification plates, and road reflectors, making it easier to detect black ice or dim the headlights of oncoming traffic. The rotary color module 220 executes the rules extracted from the rules database. For example, the rotary color module extracts the corresponding rules or executable programs. It executes the program by sending appropriate signals to the bus controller to illuminate the micro-LED panel in appropriate lighting. For instance, if an orange and black road sign is recognized, the extracted rule will be for the micro-LED panel to generate orange light to illuminate the road sign.
