Abstract
A preparing method of a quantum dot film is provided. The method includes steps of: providing an electrode layer, the electrode layer including a plurality of strip electrodes spaced apart from each other; coating a quantum dot solution onto the electrode layer; supplying a driving voltage to the strip electrode to cause the quantum dots of the quantum dot solution to aggregate toward a region corresponding to the strip electrode; and curing an aggregated quantum dot solution to obtain the quantum dot film.
