Quantum dot-based polarization built-in color liquid crystal display and manufacturing method thereof

Abstract

A quantum dot-based polarization built-in color liquid crystal display according to the present invention comprises: a light source; a liquid crystal optical unit which is positioned above the light source and controls the phase delay of light incident from the light source; a polarizing functional layer that is positioned above the liquid crystal optical unit and that adjusts the transmittance oflight; and a quantum dot light-emitting section that is positioned above the polarizing functional layer and includes a plurality of quantum dot patterns having different light-emitting characteristics in a visible light region in accordance with the intensity of transmitted light. According to the embodiment, the quantum dot patterns and the polarizing functional layer are formed in the display,therefore, the characteristics of high color purity, low optical aberration, low interference effect and the like can be realized at the same time without a color filter; ; the polarizing functionallayer can be manufactured through a solution process, so that the advantages of low cost, simplified process and large area can be realized, and the limitation of a conventional color display technology based on quantum dots can be overcome.

Description

technical field [0001] The invention relates to a polarization built-in color liquid crystal display based on quantum dots and a manufacturing method thereof. Specifically, the related in-cell polarization type quantum dot-based color liquid crystal display is characterized in that multiple dots are formed on the inner surface of the substrate constituting the liquid crystal panel A photo-luminescence (photo-luminescence) quantum dot pattern (pattern) that emits two or more different colors by light, and a polarizing function layer is formed on the quantum dot pattern through a solution-process (solution-process) ( Polarizing functional layer) and adjust the transmittance of light passing through the liquid crystal layer inside the liquid crystal panel, and make the quantum dots emit light according to the intensity of the transmitted light, so as to have low optical aberration and low interference effect (interference), High color purity (color gamut).

Problems solved by technology

As another structure, there is a structure in which an internal wire grid is introduced into another substrate of the liquid crystal panel. In this case, it is difficult to uniformly produce metal lines having a line width and height of tens to hundreds of nanometers in a large area. grid

Recently, research on fabricating nanowire grids internally by nanoimprinting lithography is underway, but large area is still the biggest problem, especially due to stamping, coating, Many complex processes such as curing, release, etching, etc., not only reduce the production yield, but also increase the manufacturing cost
