Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both, to the paper. As with digital photocopiers, laser printers employ a xerographic printing process. Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by reflecting light off an existing document onto the exposed drum.

The invention relates to a color conversion layer preparation method and a display device, relates to the technical field of laser printing, and aims to solve the problem that a method for manufacturing a color conversion layer by adopting an ink-jet printing method and a photoresist process is relatively complicated, so that the film manufacturing difficulty is relatively high. The method comprises the steps of performing at least one laser radiation process on powder laid on a substrate to form the color conversion layer on the substrate; executing the following steps in each laser radiation process: laying the powder on the substrate, and the powder being a polymer doped with quantum dots or fluorescent powder; according to the preset positions of pixel points, adopting laser to radiate the powder laid on the substrate so as to melt the powder on the radiation positions; and removing the powder which is not radiated by the laser on the substrate. According to the embodiment of the invention, the laser is adopted to radiate the powder, so that the polymer generates a melting effect, and the powder is melted at the positions of the preset pixel points, so that the color conversion layer is formed, and the manufacturing steps of manufacturing the color conversion layer are simplified.
