Abstract

The invention discloses a printing base and an inkjet printing method, belonging to the field of light-emitting device manufacturing. The printing base includes: an object loading base, an extension base, a vacuum pump and an air jet valve; the extension base is located around the object loading base, the object loading base has at least one adsorption hole for absorbing the substrate, and the extension base has At least one injection hole; the vacuum pump is connected with at least one adsorption hole, and the gas injection valve is connected with at least one injection hole, and the gas injection valve is used to inject gas around the object base platform through at least one injection hole, so that the substrate on the object base platform A solvent atmosphere is formed all around, so that the dry atmosphere of the edge pixels and the middle pixels in the substrate are consistent. The present invention can remove the test area around the display area in the substrate by increasing the extension base around the object-carrying base, thereby increasing the area of ​​the display area and further reducing the frame width of the liquid crystal display panel.

Description

technical field [0001] The invention relates to the field of light-emitting device manufacturing, in particular to a printing base and an inkjet printing method. Background technique [0002] In the preparation process of PLED (English: Polymer Light-Emitting Diode; Chinese: Polymer Light-Emitting Diode), inkjet printing technology is usually used to form red, green, and blue primary color light-emitting pixels. That is, the pre-patterned substrate of ITO (English: Indium Tin Oxide; Chinese: Indium Tin Oxide) is adsorbed on the printing platform, and the hole transport material and the solution of red, green and blue light-emitting materials are sprayed. In the sub-pixel pits on the substrate, light-emitting pixels of red, green and blue primary colors are formed. However, the drying atmosphere of the edge pixels of the substrate is inconsistent with that of the middle pixels, which will cause the drying speed of the edge pixels to be greater than that of the middle pixels,...
