Luxury brands such as BBA, Bugatti, and Hongqi have successively promoted the application of OLED taillights. (1) Audi: In 2016, the Audi TT RS became the first mass-produced model to adopt OLED taillights. Later, models such as the Audi A8 and Audi RS7 Sportback were also equipped with OLED taillights. In 2019, Audi launched digital OLED technology, which greatly increased the number of partitions from the original 4 to more than 50, allowing OLED taillights to achieve a more customized design. With the application of digital OLED technology, the Audi Q5 taillights have realized running lights for coming home, running lights for leaving home, approach indication and other modes, and the Audi A8 and Audi S8 have added dynamic turning functions. (2) Mercedes-Benz: OLED taillights were used in the Mercedes-Benz S-Class in 2017, with a total of 33 zones. The EQA concept car released this year uses the latest technology, and the light strip is a three-dimensional spiral shape. (3) BMW: Since 2015, OLED taillights have been used in M4 Concept Iconic Lights, M4 GTS, M4 CS, BMW 8 Series and this year’s previewed M4 CSL. (4) Bugatti: For the Divo model launched in 2018. (5) Hongqi: The 2020 Hongqi H9 uses OLED taillights, with 4 screens on each side, and each screen has 5 partitions.
OLED taillight applications have dropped to the 300,000 yuan level. In the domestic market, the 400,000-yuan Audi Q5L Sportback is also equipped with OLED taillights on the top-end version, enabling dynamic driving modes and 3 continuous-on modes. Other models can be optionally installed at a price of 9,800 yuan, which is a significantly lower optional price. 25,000 yuan for the Audi A8L.

OLED taillights do not require optics or heat sinks, and have the advantages of being ultra-light, ultra-thin, and flexible. The OLED light source module consists of an OLED screen body, FPC, and screen bracket. The OLED screen body is mainly composed of a substrate, a transparent electrode, an organic light-emitting layer, etc. The principle is to stimulate the organic light-emitting layer to emit light through current. Since organic materials do not need to be formed into single crystals to emit light efficiently, nor do they need to be placed on expensive crystal substrates, luminescence prefetching can cover most substrates and provide a wide-angle, low-glare, and hot-spot-free light source, which is very suitable for large-area light sources. .
According to data from OLEDWorks and Yiguang Technology, the advantages of OLED taillights include: (1) Thinness and lightness: The thickness of the OLED panel is 1 mm and the required installation space does not exceed 25 mm, while the size of inorganic LED components usually exceeds 100 mm. At the same time, the operating temperature of OLED is only 36°C, which is lower than the 60°C of LED. It no longer requires a heat sink. As a surface light source technology, it does not require complex optical devices, which can effectively reduce weight and reduce assembly production. The amount of work required for adjustment and assembly is negotiable. (2) Flexible: OLEDs can be easily stacked to produce different brightness and colors, and are also easier to process into various shapes and sizes due to their special materials.
Digital OLED technology enables light language. According to OLEDWorks, OLED panels can be designed into multiple individually addressable segments, providing high contrast between segments without crosstalk, creating the possibility for light language, allowing OLED taillights to assume the role of interactive displays in addition to signaling functions. , communicate dangers and sudden changes in vehicle speed or road conditions to surrounding vehicles or pedestrians, improving road safety. With the development of digital OLED technology, the number of partitions in OLED taillights continues to increase. For example, OLEDWorks' latest automotive OLED panel has more than 600 partitions. The digital OLED taillight jointly developed by Yiguang and STMicroelectronics has 1434 pixels, which can realize interaction. , decoration, welcome, farewell, driving outline and other functions, and shows the possibility of realizing braking, steering, reversing and other functions in the future.

Starting from 2020, Volkswagen will use Surface LED technology in ID.4, ID.6, Arteon, Taos, Tiguan and other models. The Range Rover Sport released this year also introduced Surface LED technology into a mass-produced vehicle for the first time.
Tier1 manufacturers such as Magna, Huayu Vision, Hella, and Magneti Marelli all have Surface LED car lighting technology, and generally use light guide plates, optical films, etc. to achieve uniform lighting. Surface LED taillights for Volkswagen models come from Magna, Huayu Vision, etc. Other Tier 1 Surface LED technologies include Hella’s FlatLight, Magneti Marelli’s Folia LED, etc. (1) Magna: The taillights of the Volkswagen ID.4 are supplied by Magna and adopt Surface Element Lighting technology. The minimum thickness of a single panel is only 4 mm, and the lighting animation effect can be customized through pre-programming. . (2) Huayu Vision: The IQ.Light LED through-type parallel streamer taillight for the domestic ID.6
(3) Hella FlatLight: It consists of a back cover, a light guide plate, an optical film, and a front lens. It is based on Hella's μMX (micro-optical technology, using innovative light guides) and μDP (metal coating technology, eliminating the need for covers, lenses, etc. ), SmartGlass (display technology) and other technologies, the thickness is only 5 mm, and it only requires 1W to realize all rear combination light functions such as turn signals, brake lights, and tail lights. FlatLight saves 80% energy compared to traditional taillights. According to Hella’s annual report, FlatLight will be mass-produced for an international automobile manufacturer in 2024. (4) Magneti Marelli Folia LED: Using a sandwich design of two LED screens, combining shape and texture, the thin-layer Folia LED technology can reach the thickness of OLED, but the cost is greatly reduced.
Surface LED pixels continue to improve, enabling dynamic display capabilities. Hella's digital FlatLight has achieved a significant increase in pixels. In the digital FlatLight prototype released in 2021, the front SmartGlass is divided into 44 triangular parts, making it easier to program the appearance of the new car lights. It can also be programmed through the application or Software updates enable new business models such as installing and adjusting graphics. The lights can be adjusted according to the driving mode and can display and warn road users with text or symbols such as traffic jams or icy roads, or graphics showing the electric vehicle's battery level. HELLA says it will further increase the resolution and functional range of the rear combination lights by integrating Active Matrix Displays technology.
3.Ambient lighting
3.1. Interior lights: integrated into the smart cockpit to create an immersive experience
Interior ambient lighting is used in several areas inside the cabin. Interior ambient lighting is generally used in dashboards, car doors, center consoles, ceiling lights, sunroofs, car light sheds, front and rear footrests, rear seats and other areas, in the form of light strips or dots. From the perspective of lighting forms, they include point light source direct ambient lights (composed of light distribution masks, LED circuit boards, and shells), point light source light strip ambient lights (composed of light emitting modules, light guides, and mounting brackets), point Light source surface-emitting ambient lights (composed of luminous mask, surface light guide, LED circuit board, casing), etc., are used in different areas of the cabin.
The penetration rate of ambient lighting in the domestic passenger car market is estimated to be around 30%. Based on the latest configurations and sales estimates of major models, the current penetration rate of ambient lighting in the domestic passenger car market is around 30%. According to the sales data of the Passenger Car Association and the model configuration data of Pacific Automotive Network and Bitauto, among the top 15 models in sales in the first half of this year, (1) sedans: Sagitar, BMW 5 Series come with standard ambient lights; Sylphy, New Lavida, Some versions of BYD Qin, New Bora, BYD Han, BMW 3 Series, Emgrand, etc. are equipped with ambient lights.
