Phone screens have been through major improvements over the past five years. We used to be focused on screen quality but now phones have been trying to get rid of the bezel. For those who don’t know, a bezel is simply the sides of the phone (typically a black bar, or part of the body) where there is no screen.
Now, personally I think a little bit of bezel is a good thing if it is done tastefully. Because nothing is more annoying than having a phone that when you’re trying to hold the edge you keep tapping the screen on accident. However, Oppo is reportedly working on a solution.
Oppo working on smartphone with a curved display on 4 sides.
In late 2018 Oppo Mobile Telecommunications filed a patent with the United States Patent and Trademark Office as well as the World Intellectual Property Office.
The patent describes a smartphone with a full-screen design where all four sides of the screen are rounded off. There would be no top or bottom bezel on the device which would be very slick to look at.
Part of the challenge with this is figuring out where to place many of the traditional sensors light sensors, cameras, among other things. Companies such as Samsung have simply stuck them under the glass screen (which I prefer personally compared to some of its competitors).
Oppo phone with infrared and light sensor under the screen
In November 2018, Guandong Oppo Mobile Telecommunications applied for a patent under the same name, which was also filed with both the USPTO and WIPO. This patent was published on September 26, 2019, and also mentions a full-screen design.
This patent pertains to a flat display, the device will have an ultra-thin screen border. This is not the frame of the device it is actually a translucent screen surface which no content will be display on. However, light will continue to shine through the material.
The light sensor will be placed under the screens surface in this case and due to the translucent side surface it can adjust to the brightness of the environment.
Some of the patent designs picture the sensor at the top of the screen or it could be down the side as well. The infrared sensor, will also be placed under this screen.
