Claim 6:
7. A manufacturing method for a display panel, comprising steps of:
forming a photosensitive element layer;
forming a light collimating layer on the photosensitive element layer; and
forming an active light-emitting matrix layer on the light collimating layer;
wherein the step of forming a light collimating layer comprises:
providing an aluminum substrate, putting the aluminum substrate into ethanol, and carrying out ultrasonic oscillation for 5 minutes;
taking out the aluminum substrate, annealing the aluminum substrate in an oven at 500° C. for 2 hours, and taking out the aluminum substrate after cooling; and
putting the aluminum substrate into an electrolyte, and preparing a porous alumina as the light collimating layer by a two-step oxidation method.
