Since the launch of the iPhone X, the full-screen design has become popular in the smartphone market.
Various full-screen forms such as notch screens, water drop screens, and under-screen cameras have sprung up in front of everyone. In order to provide more screen space as much as possible, manufacturers have gone to great lengths.

According to letsgodigital, in June this year, Samsung Electronics applied to WIPO (Intellectual Property Office) for a patent entitled “Electronic Equipment Including Sub-display and Its Operation Method”. The document was published on December 24.
This document depicts a full-screen smartphone with curved edges + ultra-narrow bezels. The front lens can be hidden by switching the screen layering, and it supports the use of S Pen.
How Does This Work?
When the user does not need to take a picture, the front camera and flash are hidden. When the camera needs to be used, it can be automatically adjusted to a high-pixel lens.
In other words, it uses a sub-screen to cover the camera. When you need to take a picture, pull the sub-screen to the bottom to expose the lens. So the light transmittance of the camera is not affected at all.
In addition to the automatic mode, the user can control the movement of the sub-screen through the slider next to the power button. At the same time, there is a touch sensor inside the sub-screen, and the user can also touch the area with a finger to control the movement.
Although Samsung’s patent solves the problem of light transmittance of the camera, adding a lifting module inside the phone also increases the maintenance cost of the phone, and the thickness of the phone will also increase.
Some users asked since it is also necessary to add a lifting module, why not directly make a lifting lens?
