OnePlus reveals phone with ‘invisible cameras’: Here’s how it works
OnePlus had been teasing its ‘Concept One’ smartphone since the past few days and it did finally reveal the handset at CES 2020 in Las Vegas, US. The smartphone is a ‘concept’ for now because of the technology that it features. The smartphone uses electrochromic glass at the back. It’s not your regular smartphone glass back panel but a rather interesting one that aims to make handsets more stealthy and clean-looking. So, what is the tech all about? Here are a few easy pointers.
It is an electronically tintable glass that hides the rear camera underneath and reveals only when it is in use. The organic particles on the glass create different tints when subject to an electrical field. This means that each time when a different voltage is applied, the light transmission changes, resulting in hiding or revealing the rear camera.
As shown in the OnePlus Concept One smartphone, the electrochromic glass at the back hides the rear camera setup, making the device look like a plain slab. It can simply change from a regular looking glass with cameras underneath it, to a completely opaque/tinted glass, hiding them. From outside, it is just for a better aesthetic appeal.
You can use it as a Neutral Density (ND) filter. The feature can be activated from the camera app’s Pro Mode. In this, the electrochromic glass auto adjusts if the image you are clicking is too bright so the resulting images are not blown out.
