The collimated light source includes a substrate, a film layer with a plurality of concave microstructures on the substrate, a reflective layer on the film layer, and a plurality of light-emitting parts corresponding to the concave microstructures one-to-one. Each of the light-emitting parts is located at a focal point of a corresponding concave microstructure. According to the embodiments of the present disclosure, the light emitted from each light-emitting part is reflected by the reflective layer on the corresponding concave microstructure and then exits in parallel light from a side of the reflective layer facing away from the substrate.

Abstract: A display panel includes a first substrate and a second substrate which are arranged opposed to each other. The space between the first substrate and the second substrate is separated into a plurality of sub-pixel regions. Within each sub pixel region, a first electrode, a first fluid layer, a second fluid layer, a hydrophobic dielectric layer and a second electrode are arranged in this order. The first fluid layer is made of hydrophilic liquid. The second fluid layer is made of ink. When no electric field is applied between the first electrode and the second electrode, the ink spreads over the surface of the hydrophobic dielectric layer. When an electric field is applied between the first electrode and the second electrode, the ink aggregates to expose the hydrophobic dielectric layer.

Abstract: A quantum dot ink, a manufacturing method thereof and a quantum dot light emitting diode device are provided. The quantum dot ink includes a non-polar organic solvent, a surface tension modifier and a hydrophobic quantum dot, the quantum dot ink further includes a carrier transport material, wherein phase separation is present between the hydrophobic quantum dot and the carrier transport material. After completing ink-jet printing the quantum dot ink, phase separation occurs between the hydrophobic quantum dot and the carrier transport material. Thus, the two-layer structure of a hydrophobic quantum dot layer and a carrier transport material layer is formed through one process. Not only a quantum dot light emitting device is manufactured by the method of ink-jet printing, but also the operation is simplified, and the manufacturing cost of the quantum dot light emitting device is reduced.
