The 4.46-inch display comes with a 720p resolution and having almost no bezel makes the image you see appear larger than it is.
In addition, AU Optronics demonstrated its AHVA Advanced Hyper-Viewing Angle screen. The 4.97 AHVA screen sports a full HD resolution of 1080 x 1920 pixels, and is again manufactured with LTPS technology.
Finally, for tablets, AUO has the 10-inch ultra-slim display sporting an impressive 2560 x 1600 pixels of resolutions. The display uses indium gallium zinc oxide (IGZO) for better power efficiency.
