Claim 0:
1. 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 on the photosensitive element layer comprises:
providing a metal substrate; and
putting the metal substrate into an electrolyte, and preparing a porous oxidized metal as the light collimating layer by a two-step oxidation method;
wherein before the step of putting the metal substrate into an electrolyte and preparing a porous oxidized metal as the light collimating layer by a two-step oxidation method, the method further comprises steps of:
putting the metal substrate into ethanol, and carrying out ultrasonic oscillation for a first preset time; and
taking out the metal substrate, annealing the metal substrate in an oven at a preset temperature for a second preset time, and taking out the metal substrate after cooling.
