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.

Abstract: The present disclosure provides an array substrate and a method for fabricating the same, a method for detecting alignment accuracy, and a liquid crystal display panel, wherein a dummy color resist unit is disposed on a periphery of a display area of a substrate, and a side or a center point of the dummy color resist unit is designed to be at a predetermined distance from an adjacent signal line. Therefore, it is only necessary to measure a distance between the side or the center point of the dummy color resist unit and a signal line adjacent to it, and compare the measured distance with the predetermined distance to estimate alignment accuracy of color resist units. It is not necessary to dispose detection units in a non-display area of the array substrate so that an area of the non-display area can be reduced to achieve ultra-narrow frame design.

Abstract: The present application discloses a color resist material, a filter, and a preparation method thereof. The color resist material is a trimer structure formed by polymerizing phthalocyanine dyes, wherein groups with double bonds are introduced on the phthalocyanine dyes to construct a three-molecule complex by a complexing agent, and the phthalocyanine dyes are connected by the double bonds to form a trimer structure. The color resist material with the trimer structure is stably stored in a photoresist liquid and has excellent solvent resistance, while maintains good solubility. Accordingly, a filter made of the color resist material has high transmittance and good optical performance.

Abstract: A timing controller, a display panel and a driving method are proposed. The display panel includes a display sub-pixel and a virtual sub-pixel. The display sub-pixel includes first sub-pixels, second sub-pixels and third sub-pixels. If the grayscale information of the two adjacent first sub-pixels are the same, then a driving signal of the virtual sub-pixel is the same as a driving signal of a third sub-pixel close to the virtual sub-pixel; otherwise, the driving signal of the virtual sub-pixel is the same as a driving signal of the third sub-pixels, which are outnumbered in the histogram.
