Abstract: A three-dimensional dye, a manufacturing method of the three-dimensional dye, and a photoresist mixture are disclosed. A non-planar three-dimensional dye molecular structure is constructed by adding a three-dimensional structure group into a dye molecule, thereby breaking the strong attraction force between the planar conjugation of the dye molecule. Aggregation of dye molecules are prevented, influence of dye molecules on optical paths is eliminated, and thus optical properties and color rendering properties of color filters made by a photoresist liquid are improved.

Abstract: The present invention provides an array substrate and a manufacturing method thereof. The manufacturing method of the array substrate adopts a multi-stage mask to expose and develop, so that a thickness of a remaining photoresist layer in a channel region corresponding to a display region is same as a thickness of a remaining photoresist layer in a channel region corresponding to a GOA region. Therefore, the two channel regions can be completely etched to prevent short-circuiting, and make up for defects of different action efficiency of developers caused by different densities of thin film transistors in the display region and the GOA region.

Abstract: A liquid crystal material, a liquid crystal display panel, and a manufacturing method thereof are provided. The liquid crystal material includes negative liquid crystal molecules and one or more thiol polymerizable monomers. The display panel uses a polymer film obtained by polymerization of a click chemistry reaction of a “thiol and double bond” system to anchor an orientation state of the liquid crystal molecules on the substrate surface, with few impurities and a low risk of image sticking displayed on the panel.

Abstract: A method of patterning quantum dots, a device using same, and a system thereof are provided. By providing a base between a plurality of upper electrodes and a plurality of lower electrodes, coating a quantum dot solution on an upper surface of the base, and powering the upper electrodes and the lower electrodes to form an electric field between the upper electrodes and the lower electrodes, the quantum dot solution is gathered between the upper electrodes and the lower electrodes according to an electric field distribution. Subsequently, the quantum dot solution can be deposited into a film by evaporation of a solvent, thereby obtaining a patterned quantum dot thin film on the base.

Abstract: The present invention discloses an image adaptive noise reduction method and a device thereof. The method includes: dividing an original image into a plurality of sub-blocks; performing a space conversion for all the sub-blocks; performing a significance analysis to obtain a significant characteristic map; performing a threshold segmentation on all the significant characteristic maps by a significant standard value to obtain a significant characteristic region and a non-significant characteristic region; performing adaptive filtering on the significant characteristic region and maxing an original image in the non-significant characteristic region to obtain a mixed image; and performing an image space inverse conversion for the mixed image, and outputting a final image. The present invention uses the method of dividing the image, based on the significant characteristics of the image, reducing noise reduction in the non-significant characteristic region, saving algorithm running time and hardware resources.

Abstract: A method of manufacturing a color filter and a color filter are provided. The method includes steps of manufacturing a color resist layer and an inorganic barrier layer on a base substrate. The step of manufacturing the color resist layer includes sequentially forming a first color resist, a second color resist, and a third color resist, and the first color resist, the second color resist, and the third color resist are repeatedly arranged in order in a direction along a surface of the base substrate. The step of manufacturing the inorganic barrier layer includes forming a first inorganic barrier layer covering the first color resist after the first coloder resist is formed and before the second color resist is formed. By setting the inorganic barrier layer to separate different color resists, it is possible to avoid diffusion pollution between different color resists and ensure a display performance.
