  • Unlocking future smartphones will be much more convenient


    Many modern gadgets are equipped with sub-screen fingerprint scanners, but the reading area of most models is limited to a small area. The Taiwanese company AU Optronics (AUO) presented at THE sid Display Week 2019 exhibition a working prototype of a display for a smartphone with a full-screen optical sensor capable of recognizing the owner's finger at any point of touch.

    The new product is an LTPS-display with a diagonal of 6" without cuts and holes with a resolution of Full HD+ (2160x1080 pixels) and a pixel density of 403 PPI. Its key feature was the optical fingerprint scanner, the sensor of which occupies the entire area of the matrix.

    This approach eliminates the need to remember where the sensor is — just put your finger to the front surface of the device. The declared response speed is 30 MS.

    The company also demonstrated a 6.2-inch display with a compact opening for the front camera. The company claims that the "hole" with a diameter of 4.2 mm will be barely visible on the ultra-widescreen with an aspect ratio of 21:9 and a resolution of 2520x1080. Another feature of the new item was the minimum size of the "chin" — only 1.0 mm.

    Terms of commercial launch and the price of new products will be announced later. Previously, similar technology has already been implemented by Vivo, but the date of the serial production of The Vivo Apex smartphone is unknown.
