Hidden commodity patent

According to foreign media letsgodigital, Samsung Electronics applied to the World Intellectual Property Office for a patent on electronic equipment with auxiliary display screen and its operation method on June 9, 2020, and was approved and published on February 24, 2020. This is a full-screen smartphone with a very narrow border and an arc screen. When the camera is not used, the camera and LED flash are not visible. According to the patent, there is a transparent area in the middle of the top of the screen, and the second small screen is located below the transparent area. There is a camera module directly below the small screen, which integrates dual cameras and LED flash.

The first camera can be used for biometrics, so it may have an integrated iris scanner function, while the second camera can take photos and record videos normally. Different from the off-screen camera we see now, the patent also shows a set of mechanical structure, that is, there is a small screen between the camera and the screen that can move up and down or left and right. So when we use the camera, we can put away the small screen and let the camera work normally. When we turn off the front camera, it can rise to the transparent area of the screen and display the content.

The small screen can also move left and right, so only a part of the camera module can be displayed. For example, when unlocking the mobile phone, we only need to turn on the iris recognition camera instead of the ordinary camera and flash. In this case, the small screen will be moved to one side and only the iris recognition camera will be displayed, and vice versa. Moreover, this process is fully automatic, but users can also operate it manually. The motion control of the small screen has been integrated into the power button on the right side of the device. You can also use two fingers to operate the small screen.

This small screen can be used to display time and battery status, of course, there are more functions to choose from. For example, it can also display notifications or alerts. When the user receives a message or email, the corresponding icon will appear on the small screen. Click the icon to display the complete information on the big screen. Samsung's patent is to solve the problem of poor image quality and screen display caused by insufficient light. It directly designs a transparent area on the mobile phone screen, and sets a display sub-screen at the bottom of the screen, and the camera is located below the sub-screen. In this way, when we turn on the camera, the transparent area can provide enough light, so that the imaging quality of the camera under the screen will not be greatly affected. When the camera is turned off, the small screen can cover the transparent area and display the content normally.
