Computer display capable of protecting privacy

Abstract

The invention discloses a computer display capable of protecting privacy, and the display comprises a display shell, a backlight lamp, a liquid crystal screen, a polarizing film and polarizing glassesconsistent 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 computer displayis worn, and guide grooves are formed in the display shell along the two sides of the liquid crystal screen; a driving shaft is arranged on the display shell on the back face of the backlight lamp and driven by a driving motor, a diaphragm connected end to end is wound on the periphery of the driving shaft and the periphery of the liquid crystal screen, the diaphragm is formed by splicing a polarizing film and a light-transmitting film, the driving motor is connected with a first control chip, and the first control chip is connected with a touch switch in a wired or wireless mode. The computer displayer capable of protecting privacy can be suitable for being used in the environment where displayer pictures need to be protected, the displayer pictures can be directly observed with naked eyes in the environment where the displayer pictures do not need to be protected, the two states are automatically switched, and the two using requirements are met.

Description

technical field [0001] The invention belongs to the technical field of displays, in particular to computer displays for protecting privacy. 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. There...

In order to ensure safety, it is necessary to go to a separate compartment to check these documents, and the privacy effect of the display is 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. 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 CN206848641U, 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. It is also impossible to directly share and communicate with others the images displayed on the screen when keeping confidential documents. Others must wear the same polarized glasses to observe the displayed images. Therefore, the use has certain limitations and cannot meet different use needs.
