  • Patent number: 10921635
    Abstract: The present disclosure provides a display substrate, including a base substrate, and a black matrix pattern and a color filter pattern on the base substrate. The black matrix pattern defines one or more display regions of the display substrate and a non-display region surrounding the one or more display regions. The color filter pattern includes a plurality of color filter sub-patterns, each color filter sub-pattern includes a plurality of color filter units, and each color filter unit includes a body portion. At least one of the color filter units further includes an anchoring portion extending from the body portion, and in a direction perpendicular to an extension direction of the body portion, the anchoring portion has a size greater than the body portion. The present disclosure further provides a method for manufacturing the display substrate, a display device and a mask.

  • Patent number: 8692236
    Abstract: Disclosed is a method of manufacturing an organic semiconductor thin film for an organic thin film transistor from a blend of organic semiconductor/insulating polymer. The organic semiconductor thin film is configured such that organic semiconductor nanofibrils are dispersed in the form of a network in the insulating polymer layer. This organic semiconductor thin film is formed by dissolving the blend of organic semiconductor/insulating polymer in a marginal solvent of the organic semiconductor or mixed solvent thus preparing a blend solution, which is then applied while adjusting the solubility of the solution. An organic thin film transistor using the organic semiconductor thin film is also provided. The blend thin film of organic semiconductor/insulating polymer containing only about 3 wt % of the organic semiconductor exhibits electrical properties equal to those of a thin film composed exclusively of an organic semiconductor.
