Ink-jet printing equipment for preparing quantum dot color filter

The invention discloses ink-jet printing equipment for preparing a quantum dot color filter. The ink-jet printing equipment comprises a supporting part, a printing head, an ultraviolet radiation partand a first moving part; the supporting part is used for supporting a pixel substrate; the printing head is used for spraying out a quantum dot gel solution to the pixel substrate supported by the supporting part, and the printing head is provided with a plurality of spray-out openings which are arrayed and used for spraying out the quantum dot gel solution; the ultraviolet radiation part is usedfor radiating ultraviolet to the pixel substrate so as to enable the quantum dot gel solution adhering to the pixel substrate to be cured; and the first moving part enables the printing head to be carried aiming at the state of the supporting part and move in the scanning direction. By arranging the device capable of conducting ultraviolet curing on the quantum dot gel solution in the ink-jet printing equipment, the problem that in an existing common method, polymeric monomers in the quantum dot gel solution are volatilized much can be remarkably reduced, and uniformity of all quantum dot color filter pixel units in the pixel substrate can be effectively ensured.
