Figure 1: The display area of Accumulation Technology at CES 2024 for automotive lighting and automotive display LED driver chips is divided into two parts, and the following will introduce the applications of the exterior and interior of the car body respectively.
Exterior display area of the car body:
Logo lights. The MBI1841Q and MBI1838Q LED driver ICs are suitable for use in automotive beacon applications, with a wide output current range and high withstand voltage, allowing designers to freely adjust brightness. In addition, the MBI1841Q includes different dimming controls and built-in control modes to make the car appear in a variety of lighting effects, making the car look more stylish and beautiful, as well as full LED protection and LED error reporting to improve the safety of the car.
Interactive LED matrix display grille lights (front end).
For the first time, Juji has applied its LED driver solutions: MBI5353Q, MBI5780Q and MBI5989Q to an innovative interactive front LED matrix display. These chips offer the following advantages:
Deliver high-quality visuals with 16-bit grayscale and 8K refresh rates, making the matrix display clearer and more vivid.
It supports real-time interaction, allowing the matrix display to display different messages and patterns according to the state of the vehicle and changes in the environment.
As a result, the solutions are suitable not only for matrix displays, but also for grille lights, allowing headlights to interact safely with pedestrians and other vehicles.

At CES 2024, Juji Technology showcased its multiple driver IC solutions for LED headlights, including MBI6671Q, MBI6665Q, MBI6657Q and MBI6659Q. These chips offer the following advantages:
The MBI6671Q can be used in both high and low beams, and with external MOSFETs, it improves efficiency and heat dissipation, and supports high power output. It also supports multiple circuit topologies such as boost, buck, buck-boost, and sepic, allowing designers to choose the right solution for different needs. In addition, the chip also has an LED error reporting function to ensure the safety of the lights.
The MBI6665Q, MBI6657Q, and MBI6659Q can be used for daytime running lights and provide a simple circuit design for design flexibility. The MBI6665Q also supports a variety of circuit topologies and LED error reporting to improve system reliability and safety.
Figure 3: Accumulation Technology shows LED headlights (high beams, low beams, daytime running lights) and adaptive headlights (ADB).
The MBI6353Q LED driver IC on display is suitable for adaptive headlight (ADB) applications, providing flexible, reliable and accurate lighting solutions for vehicles. The MBI6353Q can control LED matrices up to 192 pixels and has a wide output current range to make headlights brighter and clearer. It uses hybrid dimming technology (PWM PAM) to provide excellent performance in low grayscales, providing excellent contrast ratio. The adaptive headlamp combines Stacker's LED driver IC solution, Lextar's lighting system, and Elan's ADAS system, allowing the headlamp to automatically adjust the lighting angle and brightness to avoid glare to other vehicles, while improving lighting visibility and ensuring safer and more comfortable driving conditions.

In terms of rear lighting applications, Juji Technology showcased the innovative rear interactive LED matrix display and continuous tail light applications.
The MBI5353Q, MBI5780Q and MBI5989Q can be used in interactive LED matrix displays to present high-quality visuals with up to 16-bit grayscale and 8K refresh rate, and support real-time interactions, such as displaying autonomous driving, traffic conditions, warnings and reminders, charging status, braking or turn signals, etc., so that the taillights can safely communicate with other vehicles.
The MBI6353Q and MBI1841Q can be used for continuous taillights, while the MBI1841Q has a built-in control mode that allows the taillights to achieve different dimming controls and lighting effects, such as gradients, marquees or flashing, to give the rear lighting more style and personality, and improve overall visibility and road safety.

Smart cockpit on-board display Steering wheel auxiliary display.
In collaboration with Jinyu Optoelectronics and Yinghua Technology, Juji Technology will showcase a series of smart cockpit displays, offering zone-dimming mini-LED backlight display systems with different zones to meet the latest market trends. MBI6353Q, MBI6329Q and MBI6306Q and other LED driver chips have flexible zone dimming functions, which can automatically adjust the brightness and contrast of different areas according to different content to improve display quality and efficiency. The three displays on display are available in 90-zone, 384-zone, and 576-zone zone dimming schemes, which can be adapted to different sizes and resolutions.
The MBI6353Q uses hybrid dimming technology (PWM PAM) to provide excellent performance even at low grayscale, providing high brightness and a wide output current range, suitable for various application scenarios. The MBI6306Q can also be applied to glass substrates, further increasing the design options of cockpit displays.
In addition, this series of area dimming mini-LED backlit displays can also allow the steering wheel to assist the display with higher brightness and contrast, so that the display content is clearer and not affected by sunlight or other light sources.
