Abstract: The present application provides a displaying base plate and a displaying device, which relates to the technical field of displaying. The displaying device can ameliorate the problem of screen greening caused by electrostatic charges, thereby improving the effect of displaying. The displaying base plate includes an active area and a non-active area connected to the active area, the non-active area includes an edge region and a first-dam region, and the first-dam region is located between the active area and the edge region; the displaying base plate further includes: a substrate; an anti-static layer disposed on the substrate, wherein the anti-static layer is located at least within the edge region; and a driving unit and a touch unit that are disposed on the substrate, wherein the driving unit is located within the active area.

Abstract: A process for producing a surfactant having two head groups and a single tail group per molecule, including steps of: producing a compound of Formula (1) from ethanol and carbon disulfide; producing a compound of Formula (2) from a carboxylic acid and bromine; producing a compound of Formula (3) from the compound of Formula (2) and methanol; producing a compound of Formula (4) from the compound of Formula (1) and the compound of Formula (3); and producing a compound of Formula (5) from the compound of Formula (4) by a direct oxidation process or by a peracid oxidation process. The surfactant produced by the process has lower critical micelle concentration and enables a lower surface tension of a liquid as compared with prior surfactants with two head groups per molecule, thereby enabling the amount of surfactant required and thus the cost to be substantially reduced.
