  • Patent number: 12282235
    Abstract: In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the diameter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.

  • Patent number: 12265299
    Abstract: The invention provides a method for preparing a nanosized mixed crystal of cyanuric acid-coated halide perovskite, and use thereof. The method includes: (1) dispersing cesium halide, a lead salt, and urea in water, and stirring to obtain a mixed solution; and (2) adding phosphoric acid to the mixed solution, and subjecting to microwave heating, to obtain a solid after water is evaporated off, which is allowed to stand to obtain the nanosized mixed crystal of cyanuric acid coated halide perovskite. The method is simple, reproducible, and low in cost, with which mass production is achievable, and the emission wavelength of the obtained product is adjustable within a certain range through heat treatment. Due to the passivation and protection effects of cyanuric acid on halide perovskite, the prepared nanosized mixed crystal has excellent luminescence performance and stability, and is useful in the preparation of a high-color-point quantum dot brightness enhancement film.
