Embodiment 1

[0040] Quantum dots (quantum dots, QDs) are three-dimensional clusters with a size on the order of nanometers, so they are also called nanocrystals and nanodots. QDs materials are an interdisciplinary field involving physics, materials, nanotechnology and other disciplines. Due to the special structure of QDs, it has surface effects, quantum size effects, dielectric confinement effects, and macroscopic quantum tunneling effects, resulting in unique physicochemical properties and luminescent properties, which are completely different from the properties of the same macroscopic bulk materials. .

[0041] On the other hand, although the widely used liquid-crystal display (LCD) and light-emitting diode (LED) display devices have made breakthroughs in large size and high resolution, due to the spectral defects of their luminescent materials, these Display materials still have great challenges in picture quality and color fidelity [5-10]. Solving these challenges requires better l...

Abstract

The invention provides a method for preparing color blocking layers of liquid crystal display panels. The method includes steps of respectively preparing red quantum dots, yellow quantum dots and green quantum dots; mixing the red quantum dots, the yellow quantum dots and the green quantum dots with one another, dissolving the red quantum dots, the yellow quantum dots and the green quantum dots and centrifugally purifying and treating the red quantum dots, the yellow quantum dots and the green quantum dots to obtain solution of white quantum dots obtained after the red quantum dots, the yellow quantum dots and the green quantum dots are mixed with one another; respectively treating solution of the red quantum dots, solution of the yellow quantum dots, solution of the green quantum dots and the solution of the white quantum dots to obtain red photosensitive dispersion liquid, yellow photosensitive dispersion liquid, green photosensitive dispersion liquid and white photosensitive dispersion liquid; coating the red photosensitive dispersion liquid, the yellow photosensitive dispersion liquid and the green photosensitive dispersion liquid on glass substrates according to preset rules and forming the color blocking layers of the liquid crystal display panels by the aid of exposure and development manufacturing processes. The method has the advantages that the brightness and color expressive force of liquid crystal displays can be effectively improved by the aid of the method, and the color gamut of the liquid crystal displays can be effectively expanded by the aid of the method.

Description

【Technical field】 [0001] The invention relates to the technical field of quantum dots, in particular to a method for preparing a color-resisting layer of a liquid crystal panel. 【Background technique】 [0002] In general, each pixel on a liquid crystal display panel is composed of three sub-pixel units corresponding to three primary colors (red, green, blue). A liquid crystal display that displays one dot based on three colors of red, green, and blue has a problem that light utilization efficiency decreases. That is, the filters used for the corresponding R, G, and B pixels only transmit about 1 / 3 of the light incident on them, so the overall light efficiency will decrease. In order to improve the optical efficiency, a four-color pixel has been developed, that is, in addition to the R, G, and B three-color sub-pixels, a white (W) sub-pixel is also added. Since the light transmittance of the white sub-pixel is 100%, it can effectively The utilization rate of the transmitted...
