  • Patent number: 11965101
    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.

  • Patent number: 11937438
    Abstract: An organic field-effect transistor and a fabrication method therefor, including: providing a gate; depositing polymer material onto the gate to form a dielectric layer; performing supercritical fluids treatment on the gate having the dielectric layer deposited; depositing organic semiconductor layer material on the dielectric layer having been processed, to form an organic semiconductor layer; depositing electrode layer material on the organic semiconductor layer and forming an electrode layer. The dielectric properties of the dielectric layer after adopting the supercritical fluids treatment have been significantly improved. While the hysteresis effect of the dielectric layers in the OFET devices has been basically eliminated, the sub-threshold slope of the OFET is also significantly reduced, the carrier mobility is effectively improved. Additionally, an OFET switching rate after being processed is improved, and, by connecting the LEDs in series, the switching rate of the LED is increased.

  • Patent number: 8969827
    Abstract: A specimen kit having a tiny chamber is disclosed for a specimen preparation for TEM. The space height of the chamber is far smaller than dimensions of blood cells and therefore is adapted to sort nanoparticles from the blood cells. The specimen prepared under this invention is suitable for TEM observation over a true distribution status of nanoparticles in blood. The extremely tiny space height in Z direction eliminates the possibility of aggregation of the nanoparticles and/or agglomeration in Z direction during drying; therefore, a specimen prepared under this invention is suitable for TEM observation over the dispersion and/or agglomeration of nanoparticles in a blood.
