The invention relates to the technical field of inkjet printing, and provides an inkjet printing base and an inkjet printing method. The inkjet printing base includes a first stage, a heating plate installed on the first stage, and a A printed substrate on a stage and above the heating plate, the heating plate is electrically connected to the positive pole and the negative pole of the power supply respectively. In the present invention, a heating plate is installed on the first stage, and the heating plate is correspondingly located under the printing substrate, and heat is generated by energizing the heating plate and transferred to the printing substrate through the first stage. During printing, the ink When printing on a heated printing substrate, the solvent will volatilize faster, which will increase the viscosity of the ink. After the viscosity increases, the flow of solute will slow down, reduce the degree of coffee ring, optimize the uniformity of film formation, and improve the efficiency, stability and life of the device. .
Description
technical field [0001] The invention relates to the technical field of inkjet printing, and in particular provides an inkjet printing base and an inkjet printing method. Background technique [0002] Display technology has evolved from the early cathode ray tube (CRT), to liquid crystal display (LCD) and plasma flat panel display (PDP) in the mid-1980s, to the current mainstream OLED (organic light-emitting diode) / QLED (quantum dot) It shows that qualitative leaps have been completed time and time again. With the development of nanomaterial technology and equipment technology, in OLED / QLED display technology, the use of inkjet printing on rigid / flexible substrates to achieve low-cost, large-area printing has become the most favored technology. [0003] In the existing inkjet printing technology, the substrate is placed on the printing base, and the entire printing process takes several minutes to tens of minutes depending on the size of the printing substrate. During the en...
