Display having elastic polarizing film

Abstract

The invention discloses a display having an elastic polarizing film. The display comprises a display shell, a backlight lamp, a liquid crystal screen, the polarizing film and polarizing glasses consistent with the polarizing film in polarizing angle, a touch switch is arranged at the position, making contact with a human body, of a support of the polarizing glasses when the polarizing glasses areworn, the polarizing film is an elastic polarizing film, and the polarizing film is attached to and covers the liquid crystal screen. A stretching roller is arranged on one side of the display shell and driven by a motor, one end of the polarizing film is connected to the stretching roller, the other end of the polarizing film is fixed to the display shell, the direction in which the polarizing film is stretched by the stretching roller is perpendicular to the orientation direction of the polarizing film, and the motor is connected with a first control chip. And the first control chip is connected with the touch switch in a wired or wireless manner. The computer displayer is suitable for being used in the environment where displayer pictures need to be protected, the displayer pictures canbe directly observed with naked eyes in the environment where the displayer pictures do not need to be protected, automatic switching of the two states is achieved, and the two using requirements aremet.

Description

technical field [0001] The invention belongs to the technical field of displays, in particular to a display with an elastic polarizing film. Background technique [0002] In a public office work environment, due to the clutter of people, it is easy to be seen by others when you need to consult some confidential documents. In order to ensure safety, it is necessary to go to a separate compartment to consult these documents, and the privacy effect of the display is relatively poor. Existing computer displays generally include a backlight, a liquid crystal screen, and a polarizing film. After filtering through the polarizing film, the image displayed on the display can be directly observed. However, if the polarizing film is removed, the naked eye can only see a white screen and cannot directly observe The image to be displayed on the display. According to this principle, people have developed a display that prevents others from directly seeing the display on the display. Ther...

Existing computer displays generally include a backlight, a liquid crystal screen, and a polarizing film. After filtering through the polarizing film, the image displayed on the display can be directly observed. However, if the polarizing film is removed, the naked eye can only see a white screen and cannot directly observe The image to be displayed on the display. According to this principle, people have developed a display that prevents others from directly seeing the display on the display. There is no polarizing film on this display, and it can only be seen by wearing glasses with polarizing film. The picture on the display, such as a kind of peep-proof display device disclosed by CN20684864U, can only see the display picture when wearing polarized glasses, but this display device remains in a state that cannot be directly observed with the naked eye. When it comes to confidential documents, it is also impossible to directly share the screen displayed on the communication screen with others. Others must wear the same polarized glasses to observe the displayed screen, so the use has certain limitations and cannot meet different needs.
