Liquid crystal display, liquid crystal display module and liquid crystal unit thereof

Abstract

The invention provides a liquid crystal display, a liquid crystal display module and a liquid crystal unit thereof. The liquid crystal unit comprises an upper substrate, a lower substrate and a mixture of a quantum dot material and a liquid crystal material, wherein the mixture is arranged between the upper substrate and the lower substrate and comprises a red quantum dot material and a green quantum dot material; the mass ratio of the total doping amount of the two quantum dot materials to the total mass of the mixture is 0.05-5 wt%. According to the liquid crystal display, the liquid crystal display module and the liquid crystal unit thereof, through the introduction of the QD (Quantum Dot) materials, on one hand, the directional arrangement of liquid crystal molecules is promoted, so that an alignment effect is realized, and a traditional alignment film structure can be replaced; on the other hand, the liquid crystal unit is matched with a back light source of a blue or white LED, so that the promotion of a color gamut is realized, and the color expressive force of an LCD can be improved; in combination with a quantum dot and a liquid crystal system, effective utilization of the QD materials can be favorably realized, and compared with a conventional QD film and a QD tube technology, more materials are saved and more process cost is lowered.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a liquid crystal display, a liquid crystal display module and a liquid crystal unit thereof. Background technique [0002] Quantum Dot (Quantum Dot) luminescent material has the advantages of concentrated luminescence spectrum and high color purity. Using these advantages can greatly improve the color gamut of current LCD displays and improve the color reproduction ability of LCD displays. Quantum Dot TVs currently available on the market are the applications of this material The best embodiment in the field of display. Existing technologies mainly focus on encapsulating quantum dots with emission bands in R (red) G (green) B (blue) in engineering plastic film (QDfilm) or glass tube (QDtube), and placing the structure in the backlight The position between the display system and the traditional white light backlight is used to achieve the purpose of enriching the ...
