Many modern gadgets are equipped with under-screen fingerprint scanners, but the reading area of most models is limited to a small area. Taiwanese company AU Optronics (AUO) presented at SID Display Week 2019 a working display prototype for a smartphone with a full-screen optical sensor capable of recognizing the finger of the owner at any point of the touch.
The novelty is a 6 "LTPS display without cuts and holes with a resolution of Full HD + (2160×1080 pixels) and a pixel density of 403 ppi. Its key feature is the optical fingerprint scanner, the sensor of which covers the entire area of the matrix.
This approach eliminates the need for the user to remember where the sensor is located — simply place your finger on the front surface of the device. The claimed response rate 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 a super-wide screen with an aspect ratio of 21: 9 and a resolution of 2520×1080. Another new feature was the minimum size of the “chin” – only 1.0 mm.
The timing of the commercial launch and the price of new products will be announced later. Previously, a similar technology has already been implemented by Vivo, but the date of the start of mass production of the Vivo Apex smartphone is unknown.
