  • Publication number: 20180321782
    Abstract: The present disclosure provides display panel and display device. The display panel includes: a plurality of sub-pixel units defined by the plurality of data lines intersecting the plurality of scanning lines in an insulation manner. The plurality of sub-pixel units constitutes a plurality of rendering pixel units arranged in an array. Each of the plurality of rendering pixel units includes at least two adjacent sub-pixel units in a row of sub-pixel units, and a number of sub-pixel units included in each of the plurality of rendering pixel units is smaller than a total number of colors corresponding to color resists in the display panel. In each row of sub-pixel units, at least two rendering pixel units of the plurality of rendering pixel units are disposed between two adjacent touch lines. In each column of rendering pixel units, each rendering pixel unit performs color rendering with its adjacent sub-pixel unit.

  • Patent number: 7709683
    Abstract: A method of preparing a bis(thio-hydrazide amide) disalt includes the steps of combining a neutral bis(thio-hydrazide amide), an organic solvent and a base to form a bis(thio-hydrazide amide) solution; and combining the solution and methyl tert-butyl ether, thereby precipitating a disalt of the bis(thio-hydrazide amide). In some embodiments, a method of preparing a bis(thio-hydrazide amide) disalt includes the steps of combining a neutral bis(thio-hydrazide amide) and an organic solvent selected from methanol, ethanol, acetone, and methyl ethyl ketone to make a mixture; adding at least two equivalents of a base selected from sodium hydroxide, potassium hydroxide, sodium methoxide, potassium methoxide, sodium ethoxide and potassium ethoxide to the mixture, thereby forming a solution; and combining the solution and methyl tert-butyl ether to precipitate the disalt of the bis(thio-hydrazide amide).
