According to the patent document, this smart phone is the size of an ordinary smart phone at first glance, but it can be expanded to 30% of the existing screen if the screen is pulled to the right. If the user needs, he can pull out a part of the display.
The smartphone is also equipped with an off-screen camera, and the light sensor and distance sensor are also located below the upper left corner of the screen. In addition, the fingerprint sensor is also installed under the display screen. There are three vertically arranged lenses on the back, and a heart rate sensor is installed next to the camera flash.
Recently, Samsung Electronics registered the trademark Galaxy Z Slide/Z Roll in the European Patent Office. From the brand name, Z Slide is a scrolling mobile phone, and Z Roll is a sliding smart phone with a scrolling display.
Samsung Electronics has previously registered a number of patents for mobile phones equipped with scrolling screens. Samsung showed this slide phone at the International Information Display Society (SID)202 1 exhibition held in the United States recently. Some people speculate that the slide display screen opened at this time may become one of Z Roll or Z Slide.
Samsung Electronics is expected to release folding screen phones such as Galaxy Z Fold 3 and Galaxy Z Flip 2 in August this year. However, Let go digital predicts that smartphones with extended display screens, including scrolling screens, will be launched next year.
