The invention discloses a colored fluorescent particle for electrophoretic display, and relates to the field of photoelectric display, the colored fluorescent particle is of a core-shell structure, and the colored fluorescent particle sequentially comprises a core, a middle layer and a shell layer from inside to outside; the core is a pigment unit, the middle layer is a quantum dot layer coating the surfaces of pigment particles, the shell layer comprises one or more high-molecular polymers selected from polylauryl methacrylate and polymethyl methacrylate, and the surface of the middle layer is coated with the shell layer; the color fluorescent particles comprise intrinsic primary colors presented by the pigment units and compensation fluorescence excited by the quantum dot layer under light; and the compensation fluorescence is matched with the intrinsic primary color. In addition, the invention also provides a preparation process of the colored fluorescent particles. The colored fluorescent electrophoretic particle provided by the invention is pure and full in color and luster, and is more gorgeous in color under the excitation of ultraviolet rays.

This utility model discloses a projection wallcovering, relating to the field of wallcoverings. Its key technical features include an inner layer and an outer layer. A first connector is fixedly connected to the side of the inner layer away from the wall, and a second connector is fixedly connected to the side of the outer layer near the inner layer. The second connector is detachably connected to the first connector. The weave density of the inner layer is lower than that of the outer layer. In this utility model, when projection is needed, the outer layer is fixed onto the inner layer. The outer layer has a higher weave density and is flatter, and its surface is coated with a titanium dioxide coating to improve reflectivity, ensuring the optical effect of the outer layer's side away from the wall when reflecting projected light. The inner layer has a lower weave density, and its breathability is improved by the absence of padding yarn. Combined with the breathability of the linen yarn itself, this ensures the intensity of gas exchange between the two sides of the inner layer.
