Taiwanese AU Optronics today announced numerous mobile device displays and technologies, including light and power-saving displays for wearable devices, UHD 4K displays for smartphone and notebook PC, oTP-Lite (on-cell touch panel) supporting professional graphic stylus, in-cell touch panels, and a series of ultra high resolution car displays, all of which will be exhibition highlights at Touch Taiwan 2015.
AUO's 1.5 and 1.6-inch square AMOLED displays employ glass thinning method to trim the panel thickness down to just 0.45 mm. The watch designs for men and women come in two sizes. The 1.4-inchfull circle AMOLED display, having garnered both Gold Panel Awards 2015 and 2015 SID Best in Show Award, appears in a smooth, full circular contour combined with high resolution, ultra slim and light, wide color gamut and low power consumption features todemonstrate a classic wristwatch style. For the outdoors with direct sunlight, AUO presents 1.3-inch transflective LTPS display adopting Memory-in-Pixel technology, allowing images to be intelligible under sunlight while saving more power. When static images are displayed, the panel requires less than 1% of power consumed by conventional TFT-LCDs.
AUO extends the UHD 4K technology from large-sized TVs to smartphone and notebook PC applications. AUO's 6-inch UHD 4K ultra high resolution smartphone display has an ultra high pixel density of 737 PPI. With high brightness and wide color gamut, the display exhibits even more bright, saturated colors with high contrast. AUO's 17.3-inch UHD 4K ultra high resolution display for notebook PC has pixel density of 255 PPI and high color saturation of 100% Adobe RGB. Equipped with AHVA (Advanced Hyper-Viewing Angle) technology, the display retains its image quality when viewing from different angles.
AUO offers a portfolio of integrated touch solutions for all kinds of mobile devices. In terms of notebook PC applications, AUO will showcase 12.5-inch and 14-inch oTP-Lite. Without the presence of the cover lens, the devices are lighter for users to carry around more easily. In particular, the 14-inch oTP-Lite is capable of supporting professional graphic stylus. Users can write, draw or mark fluently and with precision. AUO will also present in-cell touch panels for smartphones, including the 5-inch self-capacitance in-cell touch panel employing a-Si TFT-LCD and 5.2-inch Full HD in-cell touch panel adopting LTPS process technology.
AUO also provides a lineup of car displays with high resolution, wide color gamut, wide viewing angle and high weather tolerance, meeting the high specifications of the automotive before-market applications. The company will exhibit 12.3-inch LCD for instrument cluster with the world's highest resolution, 8 to 10.1-inch high resolution LCD panels for center information display, and 8-inch oTP (on-cell touch panel).
In terms of advanced technologies, AUO will debut the 5-inch bendable AMOLED technology achieved by adopting plastic substrate processing. Integrating AUO's specially designed sensor, users can bend the panel to manipulate the size and direction of the display active area.
New Lineup of ALCD TV Panels
AUO will also have on display a series of ALCD TV displays, including the world’s slimmest UHD 4K LCD TV.
AUO exceeds current technological specifications for LCD TVs to integrate UHD 4K ultra high resolution, curved design, quantum dot wide color gamut, and HDR (High Dynamic Range) technologies to create the ALCD technology.
The new 55, 65 and 85-inch ALCD TV displays feature a 4000R golden curvature that mimics the curvature of the human eye. The quantum dot wide color gamut technology is adopted, and the design of the panels has been adjusted in accordance with the properties of quantum dots to perform its best in colors, with the color saturation exceeding NTSC 100%. Meanwhile the color gamut specification fulfills the latest UHD 4K LCD TV standards defined by international standardizations. For backlight module design, the ALCD TV displays have applied HDR technology.
The backlight can be controlled in zones to achieve higher contrast through local dimming. Coupled with AUO’s ultra-slim direct LED backlight module, the panel thickness has been greatly reduced to merely 15mm.
AUO will exhibit the ultra-slim 65-inch UHD 4K LCD TV panel for the first time. It has the thickness of merely 4.7mm and is currently the world’s slimmest UHD 4K LCD TV panel. AUO replaces conventional plastic light guide plates with glass light guide plates. The higher glass hardness can simplify the panel structure. As a result, the module thickness is significantly reduced and a sleek and clean back cover design is achieved.
