in the prior art, in the preparation of a quantum dot color filter by inkjet printing, generally, after all sub-pixel grooves of the same color in a pixel substrate are filled with quantum dot glue solutions, the pixel substrate is moved out of a printing cavity to other ultraviolet curing devices for complete curing, but in the method, the difference between the film formation and the size thickness of the initial sub-pixel groove and the final sub-pixel groove is large. This application is totally different with current common technology, adopts the shower nozzle that contains ultraviolet lamp, adopts ultraviolet irradiation immediately after printing the inkjet of quantum dot glue solution to the sub-pixel groove, carries out semi-curing or solidification completely to the quantum dot glue solution, and the reduction that can show like this can be polymerizable monomer's between the different sub-pixel grooves volatility to guarantee the homogeneity of quantum dot membrane in each sub-pixel groove.
In an exemplary embodiment, as shown in fig. 1, there is provided a nozzle 100 for printing quantum dot paste, the nozzle 100 including a plate body 110, and a plurality of nozzle openings 120 disposed in the plate body 110; and an ultraviolet lamp 130 disposed in the plate body 110.
In an exemplary embodiment, as shown in fig. 2, there is provided a nozzle 100 for printing quantum dot paste, the nozzle 100 including a plate body 110, and a plurality of nozzle openings 120 disposed in the plate body 110; and an ultraviolet lamp 130, the ultraviolet lamp 130 being disposed outside the plate body 110 and integrally or detachably connected with the plate body 110.
In the present application, the ultraviolet lamp 130 and the plate body 110 are preferably moved in synchronization regardless of the positional relationship therebetween. The irradiation direction of the ultraviolet lamp 130 is substantially the same as the injection direction of the nozzle opening 120, and when the nozzle 100 scans and moves, the quantum dot glue solution is firstly printed into the sub-pixel groove, and then the ultraviolet lamp irradiates the quantum dot glue solution, so that the movement position of the nozzle opening 120 is prior to the movement position of the ultraviolet lamp 130 along the movement direction of the nozzle 100, and the ultraviolet irradiation to the quantum dot glue solution after printing can be ensured.
