Touch Taiwan 2025 will be held at the Taipei Nangang Exhibition Center from April 16 to 18. Micro LED application areas have expanded to home theaters, smart cockpits, retail department stores, augmented reality, and wearable devices. It has the advantages of being thinner, higher brightness, low power consumption, and small size. The main exhibitors include Ennostar, AUO, Aledia, WG-TECH, and Dongjie (Contrel), PlayNitride, Innolux, etc.

Thanks to the unremitting efforts of many equipment, materials, panels, and brand manufacturers, the Micro LED industry has seen the successful mass production of Samsung Micro LED TVs and Tag Heuer Micro LED watches. In addition, AUO, Leyard, Unilumin, Lenovo, Hisense, BOE, Chenxian, Tianma, Jianyao Display Technology (JBD), etc. have demonstrated Micro LED display applications, Micro LED display Continue to be regarded as a key project for the long-term development of advanced displays.

According to TrendForce’s analysis, Micro LED displays are used in home theaters, transparent displays in retail department stores, automotive displays (transparent displays for car windows, heads-up displays, multi-form central control displays - Morphing Center Control), augmented reality glasses, etc. In addition, optical communication achieves ultra-low latency and stable communication, mainly due to the use of photon technology to replace traditional electronic technology to transmit data. Micro LED has the lowest energy consumption and is most suitable for short-distance transmission within 10 meters. The data transmission density is as high as 20 Tbps/mm2 and the energy consumption is only

Ennostar Fucai

Fucai actively promotes the dual value-added engine strategy, adding value and upgrading from two major directions: field and solution, focusing on 3+1 with high added value. Applications include automotive, advanced display, smart sensing, as well as new fields such as optical communications and high conversion efficiency III-V solar cells, strengthening the competitive advantage of the optoelectronic semiconductor industry.

As the demand for high-speed optical communication modules in AI servers explodes, Fucai has accelerated its layout in the optical communication market and developed a comprehensive layout of short, medium and long-distance optical communication light sources, including Micro LED / VCSEL / CW DFB laser. Micro LED consumes the lowest energy and is most suitable for short-distance transmission within 10 meters; VCSEL is suitable for 56 Gbps PAM4; CW DFB laser is used for silicon photonic transmission and is used for high-speed transmission above 1.6 Tbps.

For the Micro LED market, Fucai has established complete technical capabilities from epitaxy to mass transfer, and can provide COW and COC services. In order to further improve the convenience for end customers in the final mass transfer (COC 2), Fucai has launched an ECOC 1 temporary carrier board design with high yield and better uniformity.

With the European Union making it mandatory for new cars to be equipped with a Driver Monitoring System (DMS) on July 7, 2026, the market demand for related technologies has increased rapidly. The Low Red Glow IR LED / VCSEL solution launched by Fucai Technology can reduce the interference of the monitoring system on the driver's vision. The driving monitoring system can effectively detect the driver's inattention, failure to look ahead and closing eyes due to fatigue, which greatly improves driving safety.

AUO AUO

This 127-inch TV is made up of the world's largest 42 (41.6)-inch Micro LED display module, with a display brightness of up to 1,000 nits. The 42 (41.6)-inch LTPS backplane eliminates the need for side-plated wire technology, significantly improving production yield. At present, AUO not only provides products to Hisense, but also sends samples to Korean manufacturers. The A.R.T. technology developed by AUO can reduce the reflectivity, not only presenting black more perfectly, but also making other colors more vivid.

The unbounded transparent display interface (Horizon Image Glass) integrates the instrument panel, center console and passenger display through in-car computing solutions to present an integrated panoramic view, providing passengers with clear forward vision, necessary information and entertainment functions for driving. The hidden intelligent driving interface (Foldable Cruise Pilot) uses a roll-up instrument panel to allow the driver to freely switch between driving and autonomous driving. After the instrument panel and steering wheel are stored, the driver will have more space to use, providing more possibilities for future autonomous driving modes.

The Morphing Center Control only displays a flat surface when not in use. When operated, the display will dynamically rise and transform into 3D physical buttons, supporting various control methods. The flexible characteristics of Micro LED display are used to improve the smoothness of human-computer interaction and thereby enhance driving safety.
