Embodiment 1

[0051] An embodiment of the present invention provides a display device, such as image 3 As shown, it includes: a frame and a liquid crystal panel located in the frame, the liquid crystal panel has a first substrate, a second substrate and a liquid crystal layer 3 between the first substrate and the second substrate, and the side of the first substrate away from the liquid crystal layer 3 with polarizer 2; also includes:

[0052] The analyzer 4 is movably arranged on the side of the second substrate away from the liquid crystal layer 3 .

[0053] The polarizer 4 has a polarizing function, and can be movably arranged on the side of the second substrate away from the liquid crystal layer 3. That is, when the display device needs to display normally, the polarizer 4 is located on the side of the second substrate away from the liquid crystal layer 3. The polarizer 4 cooperates with the polarizer 2 to display a normal picture; when the display device needs to be kept secret, the ...

Embodiment 2

[0058] Such as Figure 4 As shown, further, the display device provided by this embodiment also includes a fixing mechanism, which is used to detachably install the polarizer 4 on the display device, so that the display device can be displayed between the normal display screen and the abnormal display screen. convert.

[0059] The above-mentioned fixing mechanism can have various structures, and the fixing structure is not necessarily fixed on the display device, as long as the analyzer 4 can be fixed on the display device, the structure of the fixing mechanism listed here is only a part of the structure , not all structures.

[0060] structure one

[0061] Such as Figure 4 As shown, the above-mentioned fixing mechanism is: a mounting groove 51 provided on any two opposite sides of the outer frame 5 and allowing the polarizer to be embedded, at least one of the two mounting grooves 51 is a through groove. The two installation grooves 51 can be arranged on the left and rig...

Embodiment 3

[0077] Such as Figure 9 As shown, the analyzer provided in this embodiment includes: a first transparent electrode layer 81, a polarizing layer having a liquid crystal material and a dichroic dye, and a second transparent electrode layer 82 arranged in sequence;

[0078] When no voltage is applied to the first transparent electrode layer 81 and the second transparent electrode layer 82, the liquid crystal molecules 83 and the dichroic dye molecules 84 in the polarizing layer are all aligned horizontally;

[0079] When the first transparent electrode layer 81 and the second transparent electrode 82 are pressurized, the orientations of the liquid crystal molecules 83 and the dichroic dye molecules 84 in the polarizing layer are all along the direction of the electric field.

[0080] The dichroic dye mainly selectively absorbs polarized light (functions as a polarizer), and deflects along with the polarization of the liquid crystal molecules 83 . The deflection of the liquid cr...

Abstract

The invention relates to a display device and a display system. The display device comprises a frame and a liquid crystal display (LCD) panel arranged in the frame. The LCD panel is provided with a first base plate, a second base plate, and a liquid crystal layer which is placed between the first base plate and the second base plate, a polarizing plate is arranged on one side, deviating from the liquid crystal layer, of the first base plate, and the LCD panel further comprises an analyzing part which is movably arranged on one side, deviating from the liquid crystal layer, of the second base plate. According to the display device, rays of light emitted by backlight become linearly polarized light by polarizing of the polarizing plate, and the linearly polarized light can permeate the liquid crystal layer. When the display device is required to keep confidential, a user needs to wear a pair of polaroid glasses to watch. When the display device is not required to keep confidential, a user can see effective image information on a screen through the analyzing part. Therefore, the display device can be converted between a normal display picture and an abnormal display picture, so that a user is free to choose whether to wear polaroid glasses or not to watch. Thus, the display device has higher usage flexibility.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a display device and a display system. Background technique [0002] As we all know, liquid crystal display has completely replaced cathode ray tube (CRT, Cathode Ray Tubes) display. Emerged as the times require, nowadays, thin, light, low power consumption, multi-functional green display devices have become the common pursuit of everyone. [0003] Technological innovation in the field of liquid crystal display is inseparable from the continuous improvement of people's demand for various products in life. With the continuous improvement of people's demand for products, scientific research workers continue to improve products, for example: the viewing angle problem of liquid crystal itself has brought advanced super-dimensional field switching technology (ADS, Advanced Super Dimension Switch), in-plane switching technology (IPS) , In-Plane Switch), multi-quadrant...
