Mobile terminal and display system capable of defining viewing range of screen content

Abstract

The application discloses a mobile terminal and a display system capable of defining the viewing range of the screen content. The mobile terminal capable of defining the viewing range of the screen content comprises a screen and a convex lens. The convex lens is disposed on the light-emitting side of the screen. The screen is arranged at the focus position of the convex lens such that light emitted by the screen forms parallel light by passing the convex lens.By adoption of the above mode, the display content of the mobile terminal is prevented from being viewed by people.

Description

technical field

[0001] The present application relates to the field of display technology, in particular to a mobile terminal and a display system that limits viewing range of screen content. Background technique

[0002] In daily life, we always inevitably use terminals such as mobile phones and computers to check some private or important information in public places. However, there are often other people present in public places, and when we view information, it is easy to be seen by others, resulting in information leakage.

[0003] Therefore, there is an urgent need to solve the problem of how to prevent others from peeping when the user uses the terminal to view information. Contents of the invention

[0004] The present application provides a mobile terminal and a display system that limit viewing range of screen content, which can prevent others from viewing the display content of the mobile terminal.

[0005] The first aspect of the present application provides ...

Embodiment Construction

[0020] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
