With the advancement of intelligence and premium solutions for the global automotive industry, vehicles have evolved from simple automotive tools into personalized, digitalized entertainment hubs. Nevertheless, the industry requires high-value solutions that meet strict safety standards, requiring suppliers to demonstrate proficiency and provide comprehensive solutions to secure partnerships with leading automakers. Ennostar (TWSE: 3714) leverages the extensive experience of its subsidiaries in automotive optoelectronics to enhance vehicle integration. Through the strategic merger, the company will consolidate resources, upgrade technology, and strengthen its market presence. This will allow Ennostar to deliver more advanced and comprehensive solutions that meet increased market demand.

Automotive Transformation in Accelerating Market Expansion
Ennostar will merge EPISTAR and Lextar into a single subsidiary, prioritizing high-value sectors in the automotive industry. It includes advanced display, smart sensing, and emerging markets like AI-powered optical communication—i.e., the 3+1 strategy. This consolidation will boost R&D efficiency while enhancing upstream epitaxy and chip technological integration with downstream packaging and module solutions. It enables more competitive, innovative solutions while driving market expansion.

Key Technologies and Innovations
High-Zone Adaptive Driving Beam (ADB) Headlamp
Ennostar utilizes Micro and Mini LED technology to produce ADB light sources for headlamps. This enables precise control over thousands of individually operated light zones (i.e., pixels), enhancing safety to support graphical information displays. The ultra-fine pitch of Micro LEDs at less than 10 μm allows seamless CMOS integration, further improving light control.

Micro LED Transparent Display & Mini LED Sunroof
As demand for intelligent cockpits and personalized displays accelerates, Ennostar's Micro LED visible display for vehicle windows offers over 70% transmittance and 2,000 nits of brightness. This ensures optimal visibility even in sunlight. The full-color Mini LED sunroof provides 80% transmittance, delivering immersive, vivid user experiences while maintaining exterior visibility and the transmission of natural light.

Intelligent Ambient Lighting
European and American luxury car brands are expanding their use of intelligent ambient lighting. Ennostar, in partnership with Innova Semi, has developed the world's first LED exterior and interior lighting modules with a driver IC featuring dynamic temperature compensation. The solution integrates blind-spot detection technology, enhancing visual alerts and safety.

Intelligent Exterior Matrix
As demand for vehicle personalization and brand identity accelerates, Ennostar's high-brightness, high-contrast LED technology provides pixel-level light control. This technology supports dynamic changes in vehicle information and brand logos. These specially designed automotive display modules effectively reduce optical crosstalk, minimizing the need for added optical tuning while improving display performance and lowering costs.

High-Sensitivity Sensor Systems
With the European Union mandating driver monitoring systems in 2024, market demand is expanding rapidly. The low red-glow IR LED and VCSEL solutions that Ennostar offers mitigate driver distraction significantly while enhancing sensitivity and strengthening driving safety. Furthermore, Ennostar is advancing gesture recognition and array-type temperature sensing technologies, supporting next-generation intelligent driving applications.

Mini LED Full-array Local Dimming Backlights
As the development of new energy vehicles spurs demand for high-performance in-cabin displays, Ennostar's Mini LED full-array local dimming backlight technology facilitates precise control of thousands of dimming zones. This technology, integrated with next-generation driver ICs, optimizes cost control for high-zone LED backlight units, accelerating intelligent cockpit development.

Ennostar will Showcase Comprehensive Automotive Solutions at Touch Taiwan 2025
Ennostar is participating in Touch Taiwan 2025 from April 16th to 18th. It will showcase a broad set of optoelectronic solutions. The exhibition encompasses interior and exterior automotive displays, ambient lighting, and intelligent sensing applications, exhibiting technological and innovative leadership in the automotive industry.
