Abstract

The invention relates to the technical field of ink-jet printing, and particularly discloses printing liquid for printing Bank, the printing liquid comprises ink, and the ink comprises the following components: 5%-30% of absorptive filler or light reflective filler; 15-30% of an optical resin; 3-10% of a dispersion matrix; 0.5-3% of a photoinitiator; 5-15% of a thermosetting resin; and a solvent.Further, an inkjet printer and a Bank preparation method using the inkjet printer are disclosed. The printing liquid provided by the invention can be suitable for the ink-jet printer to print a Bank,the Bank printed by the printing liquid has color or light reflection property, optical crosstalk between sub-pixels can be avoided, the selection of materials can meet the requirement of mu LED display, the preparation method is realized through the ink-jet printer, and the process of one-time printing and one-time heating of the Bank is realized. According to a multi-time laminated printing heating method, large-thickness Bank preparation can be met, the printing area can be selected according to the actual situation, the whole pixel defining layer does not need to be prepared, resources aresaved, and the working procedure is shortened.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a Bank printing liquid, a Bank preparation method and an inkjet printer. Background technique [0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art. [0003] The method of fabricating organic light-emitting devices (OLEDs) and quantum dot light-emitting devices (QLEDs) by solution processing is an important direction for the development of display technology in the future due to its advantages of low cost, high productivity, and easy realization of large sizes. Among them, inkjet printing technology is considered to be the most effective way to realize low-cost and large-area full-color display of OLED and QLED. Inkjet printing technology is a process that can directly pattern deposited thin films, and can realize efficient patterning on flexible and large-area substrates. Inkjet printin...
