Embodiment 1

[0042] This embodiment provides a liquid crystal cell, comprising two substrates and a liquid crystal layer located between the two substrates, and switching between 2D and 3D display modes by controlling the deflection of the liquid crystal layer;

[0043] Wherein, ferric iron tetroxide nanoparticles with a mass ratio of 1% are added to the liquid crystal layer.

[0044] The liquid crystal layer in this embodiment adopts the liquid crystal grating method. When a voltage is applied on the two substrates, the ferroferric oxide nanoparticles convert electromagnetic energy into thermal energy, which increases the temperature at the applied voltage and reduces the viscosity coefficient of the liquid crystal. Accordingly, the response time of the liquid crystal is reduced, thereby improving the response speed of the 3D liquid crystal display device, avoiding the occurrence of crosstalk and image shaking, and improving the display effect of the naked-eye 3D liquid crystal display dev...

Abstract

The invention relates to the technical field of display, and in particular relates to a liquid crystal box, a manufacturing method of the liquid crystal box, and a display device. The liquid crystal box comprises two base plates, and a liquid crystal layer positioned between the two base plates; the 2D and 3D display mode are switched by controlling the deflecting of the liquid crystal layer; ferroferric oxide nanoparticles are arranged in the liquid crystal layer. According to the liquid crystal box, the manufacturing method and the display device, the ferroferric oxide nanoparticles which can generate heat under the voltage effect are added to the liquid crystal layer, so that the viscous coefficients of liquid crystal can be minimized, and as a result, the response speed of a 3D liquid crystal display device can be improved, and the naked eye 3D liquid crystal display effect can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal cell, a manufacturing method thereof, and a display device. Background technique [0002] Liquid crystal displays are used more and more widely in modern life, such as mobile phone display screens, Note Book display screens, GPS display screens, LCD TV display screens, etc. With the advancement of science and technology, because traditional displays can only display flat images, they can no longer meet people's requirements for display quality. 3D display has been extensively studied in recent years because it can make the picture become three-dimensional and realistic, the image is no longer limited to the plane of the screen, and the viewer has an immersive feeling. 3D display devices can be mainly divided into two types: glasses-wearing and naked-eye-type. Glasses-wearing 3D display devices need to wear specific 3D glasses when viewing. If you don’t wear 3D ...
