Abstract: An aqueous polymer is formed by neutralizing a copolymer modified by polyalkylene glycol with ammonia, primary amine, secondary amine, inorganic base, or a combination thereof, wherein the copolymer is copolymerized from an anhydride monomer with a double bond, a monomer with a double bond, and an initiator. The aqueous polymer can be mixed and dispersed with water and pigment powder to form a dispersion. The dispersion can be mixed with binder to form an aqueous paint.

Abstract: A polymer is formed by capping a copolymer-graft-polylactone with an alcohol, wherein the copolymer is copolymerized from an anhydride monomer with a double bond, a monomer with a double bond, and an initiator. The polymer can be mixed with an organic solvent and pigment powder to form a dispersion. The dispersion can be mixed with a binder to form a paint.

Abstract: A color conversion unit is provided. The color conversion unit includes a substrate and a color conversion layer. The substrate includes a hole. The color conversion layer is embedded in the hole of the substrate, wherein a ratio of a width to a height of the color conversion layer is between 1:1 and 1:15, and a color conversion mixture used to form the color conversion layer is cured by excitation light wavelength between 385 nm 1180 nm. A micro light-emitting diode disposed under the color conversion layer is used to provide light to the color conversion layer.
