The present disclosure provides a light-emitting device. The light-emitting device includes a substrate layer and pixel isolation structures disposed on a first surface of the substrate layer, a plurality of sub-pixel regions isolated from each other are formed between the pixel isolation structures, and the light-emitting device further include a plurality of light-emitting units disposed one-to-one in each of the sub-pixel regions for emitting different wavelengths of light, the light-emitting units being electroluminescent devices, and an initial external quantum efficiency of each of the light-emitting units being different; a plurality of light extraction structures disposed one-to-one in at least part of the plurality of sub-pixel regions for increasing an external quantum efficiency of the corresponding light-emitting unit, reducing deviations of the actual external quantum efficiency of each of the light-emitting units.

Light-emitting device

The present disclosure provides a liquid guiding component and a using method and application thereof. The liquid guiding component includes a plurality of liquid guiding grooves, each of which includes at least one inlet end, at least one outlet end, and a groove wall connecting the inlet end and the outlet end, the liquid guiding component includes a first side and a second side arranged opposite to each other, each of said inlet ends is arranged as liquid inlet on the first side and each of the outlet ends is arranged as the liquid outlet on the second side, and the liquid guiding grooves are used to transport liquid from the inlet ends to the outlet ends. The liquid guiding component can be used to precisely control the movement direction of the ejected ink.

Liquid guiding component and using method and application thereof

A coating method, a coating device and a light-emitting device, the coating method comprises: controlling an ink supply device to stop supplying ink to a micro nozzle when it is determined that the lowest end of an ink droplet from the micro nozzle reaches a first position; determining that the distance between the end of the micro nozzle and a substrate reaches a second distance, the second distance being preset; controlling the ink supply device to continue to supply ink, and controlling the micro nozzle to move relative to the substrate for a pattern coating. The disclosure provides a good pattern forming solution, thereby avoiding the technical problem in the prior art of inkjet printing apparatuses easily causing nozzle clogging.

Coating method, coating device and light-emitting device

A manufacturing method for a light emitting device, a light emitting device, and a hybrid light emitting device, the manufacturing method comprises the following steps: step S: disposing a mask plate having a plurality of hollow portions on a substrate; step S: applying, by using a solution method, ink on a surface of the substrate by using the hollow portions; and step S: drying or solidifying the ink on the surface of the substrate to form a light emitting layer or a functional layer.
