Embodiment approach

[0041] In the present invention, the second polarizer 130 can be removed to cover the effective display area of ​​the display panel 100 through various implementations. As the first embodiment of the present invention, such as figure 1 with figure 2 As shown, the display panel 100 may include a first fixing member 140 disposed on the light emitting side of the liquid crystal cell 110 , and the second polarizer 130 is detachably connected to the first fixing member 140 .

[0042] Such as figure 1As shown, when the display panel 100 is in a non-secret working state, the second polarizer 130 is connected to the first fixing member 140, the second polarizer 130 is located on the light emitting side of the liquid crystal cell 110, and can cover the effective display area of ​​the display panel 100 .

[0043] Such as figure 2 As shown, when the display panel 100 is in a confidential working state, the second polarizer 130 is removed from the first fixing member 140 so that the...

Abstract

The invention discloses a display panel which includes a liquid crystal cell; a first polarizer, arranged on a light inputting side of the liquid crystal cell; and a second polarizer, a polarization direction of which is perpendicular to a polarization direction of the first polarizer, wherein the second polarizer is detachably arranged on a light outputting side of the liquid crystal cell and is able to cover a valid display region of the display panel. The invention also discloses a display device which includes above display panel and polarized glasses. When there are no confidential files, the second polarizer covers a valid display region of display panel; when there are confidential files to be processed, the second polarizer is removed from the valid display region of display panel. Therefore, it is possible to effectively improve the availability of the display panel and the display device having said display panel.

Description

technical field [0001] The present invention relates to the field of display, in particular to a display panel and a display device including the display panel. Background technique [0002] At present, when processing some documents that need to be kept secret, it is necessary to set the display device for processing the documents at an office location with better confidentiality, and only a small number of participants are allowed to enter the above-mentioned office location for office work. [0003] When there is no document that needs to be kept secret, the display device installed in the office with better confidentiality can only be left idle, which greatly reduces the utilization rate of the display device. Contents of the invention [0004] The purpose of the present invention is to provide a display panel and a display device comprising the above display panel. The display panel and the display device provided by the present invention can have high utilization rat...
