Transparent liquid crystal display device and manufacturing method thereof

Abstract

The invention provides a transparent liquid crystal display device and a manufacturing method thereof. A polymerizable monomer can be mixed into liquid crystal molecule; the polymerizable monomer is polymerized under UV-light to form a polymer net for connecting upper and lower base plates; the polymer net can stabilize the initial alignment of the liquid crystal molecule, so that the response speed of the liquid crystal molecule is increased. Furthermore, the polymer net liquid crystal with quick response characteristics is used together with a field sequential type backlight system; the field sequential type backlight system is used for sequentially emitting red, green and blue light to realize colorful display, so that the colorful light-filtering layer is omitted and transparent display in high penetration rate can be realized; the dichroism dyeing molecule is added into the liquid crystal monomer; the dichroism dyeing molecule is utilized to absorb the light with polarization direction parallel to long axis direction and realize light polarization through the characteristic that the polarization direction of the light is vertical to the long axis direction, so that a polarization layer can be saved, the penetration rate of the transparent liquid crystal display device can be increased and the production cost can be lowered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transparent liquid crystal display device and a manufacturing method thereof. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the ...

Problems solved by technology

[0005] For liquid crystal displays, it is usually necessary to use red, green, and blue color filter layers to achieve color display, because color filters filter 66.7% of light, resulting in poor penetration

In order to improve the penetration of the transparent liquid crystal display device, you can use the field sequential liquid crystal display (Field-Sequential Color Liquid Crystal display) mode, the field sequential liquid crystal display mode is to make the color of the light illuminated by the backlight system to the liquid crystal display Segmentation is performed in rotation for color display, without the need for a color filter layer, which greatly improves the transmittance of the display device. However, in the field sequential liquid crystal display mode, the liquid crystal display device needs to have a fast response
