Article By : Junko Yoshida

R&D achievements of local research organisations and local vendors push design boundaries in this year's AutoTronics Taipei.

In addition to a host of automotive parts and components, this year’s AutoTronics Taipei highlighted R&D advancements made by local vendors and research institutes, making Taiwan ready for the coming era of highly automated vehicles.

HUD designs go all out

E-Lead has been serving the automotive industry over the last 20 years, supplying everything from dash cams and rear-seat multimedia entertainment systems to tier ones and car OEMs.

The company's latest additions include a host of heads-up display (HUD) units tailored for a wide range of OEMs’ needs. Dennis Chen, manager at E-Lead, pointed out that the product lineup includes an aftermarket HUD E-Lead developed with Baidu, China’s Internet giant. This is the only HUD approved by Baidu for compatibility with their Internet of Vehicles spec, branded by Baidu as “CarLife,” he explained.

Another E-Lead product is a new windshield-type augmented reality (AR) HUD that features special optical design. “You can view all the info on the HUD, even with your sunglasses on,” said Chen. This is an advancement E-Lead’s competitors have yet to match.

ITRI showcases wide-view HUD

The Industrial Technology Research Institute (ITRI) showed off its long distance floating multi-screen HUD. It allows the driver to handle all the traffic information in a safe condition and reduces the risk of eye fatigue and distraction, explained Ming-Chieh Chou, senior engineer working at smart microsystems technology center at ITRI.

ITRI’s wide-view HUD uses laser projector technology. The HUD module combines microscanning optical engine with optical mirror. Through a long distance floating light path design, the image screen can be projected at a 2-metre distance in front of the car windshield, with a size up to 26 inches, according to ITRI.

The research institute explained that its unique beam splitter technology can produce three individual displays by using a single projector. The team also developed high-speed image distortion compensation technology, allowing an individual correction to be made for each display.
