Exhibition highlights include a complete portfolio of LTPS LCDs for notebook PC, with UHD 4K ultra high resolution, ultra narrow border, and low power consumption. For AMOLED, AUO will demonstrate world’s first 1.2-inch and 1.4-inch true circle AMOLED smartwatch displays and 5-inch foldable touch AMOLED for future wearable or phablet applications. A new suite of ultra high resolution, free-form, and curved automotive displays, and 15.6 to 35-inch LCDs for gaming displays incorporating high resolution, ultra high refresh rate as well as bezel-less and curved design will also be showcased.

AUO led the industry in mass producing UHD 4K LTPS LCD for notebook PCs, and will demonstrate a stellar lineup of notebook PC LCDs at this year’s Display Week highlighting ultra narrow border and power-saving features, realizing the full potential of LTPS technology. Both 13.3-inch and 15.6-inch UHD 4K LTPS LCDs adopt a new MUX (multiplexer) design, which effectively reduces the width of the panel’s bottom border. In particular, 13.3-inch UHD 4K LTPS LCD has a high pixel density of 332 PPI and 1.5 mm-only ultra narrow border to allow much more display active area. At just 2 mm thick, the LTPS LCD reveals an extremely sleek and thin profile.

The 13.3-inch UHD 4K ultra low power LTPS LCD boasts logic power consumption of less than 1 watt, around 40 percent lower than conventional 60 Hz models. The LTPS LCDs are in line with the trend for slimmer and lighter, and more power-saving mobile devices with higher screen-to-body ratio, perfect for professional and hybrid notebook PCs.

In terms of smartwatch applications, AUO owns the industry’s most complete AMOLED product line, with the latest additions being the world’s first 1.2-inch and 1.4-inch high resolution true circle AMOLED displays with high pixel density of 326 PPI. AUO took circular design to the next level by creating slim salient corner on the two displays with the width of merely 2.2 mm and 2.34 mm, respectively. This contributes to a true circle display appearance, lending flexibility for watch brands to be more creative with their designs. Furthermore, both displays use around 30 percent less power than other models in the market, showing impressive power-saving strength.

By administering an enhanced structural design, the 5-inch foldable touch AMOLED allows a folding radius of 4 mm while still delivering HD grade image quality and 95% coverage of the BT.2020 color gamut. In addition, the display has touch sensor and cover film integrated and is still only 0.1 mm thick, creating more inspirations for future wearable or phablet designs.

Over the years AUO has accumulated profound experience in the making of high-end car displays, for applications ranging from instrument cluster, center information display (CID), in-car entertainment system to rear-view mirror. The 8.9-inch LCD for rear-view mirror comes with a full mirror design, with AHVA wide viewing angle, high brightness, fast response time, and free-form narrow border design, offering a wider field of view to substantially increase driving safety.

For instrument cluster applications, AUO will show 12.3-inch full HD free-form LTPS LCD with AHVA wide viewing angle, narrow module border and low power consumption features. With demand for ultra high contrast ratio next-generation car displays, AUO has developed 12.3-inch full HD AMOLED display with superior features, including ultra high contrast ratio, super fast response time, and high color saturation. The 27-inch full HD panoramic LCD combines two displays to form an all-encompassing and stylish design, meeting the trend for streamlined car interior design.

In terms of advanced technology for center information display (CID), 3.5-inch flexible plastic LCD applies a colorless PI (polyimide) plastic substrate and COG (Chip on Glass) direct bonding, and develops a flexible backlight unit to create a highly flexible display.

AUO has built an impressive product lineup for professional grade gaming monitor and notebook PC. The LCD panels integrate high refresh rate, large-sized display, high resolution, and bezel-less curved design. With application to gaming notebook PCs, AUO presents 15.6-inch and 21-inch AHVA LCD panels with high resolution, high refresh rate and fast response time. Notably, the world’s first 21-inch WFHD (2560x1080) ultra-wide curved LCD has a high 120Hz refresh rate and 4 ms response time, while 15.6-inch WQHD (2560x1440) LTPS LCD demonstrates 188 PPI ultra high pixel density and equally high 120Hz refresh rate, delivering perfect image quality and motion performance.

During Display Week 2017, AUO Chairman & CEO Mr. Paul SL Peng will deliver a keynote speech titled "The Warring States Era of Display Technologies" on May 23. AUO will also present several conference papers at the oral sessions of Display Week Symposium, with a paper titled “Achieving a Foldable and Durable OLED Display with BT.2020 Color Space Using an Innovative Color-Filter Structure” granted the Distinguished Paper Award. It is hoped that further exchange of ideas can be achieved for more inspirations to power the advancement of display technologies.
