Manufacturing method for increasing readable contrast of organic light emitting diode

摘要

A manufacturing method for increasing the readable contrast of an organic light emitting diode (OLED) darkens the color scale by means of an insulating layer of the OLED to reduce the interference generated by the cathode reflection during the incidence of light source on the OLED. The technology of the present invention primarily mixes the insulating materials and additives to make a black layer material and coat such black layer material on the conductive substrate to darken the color scale of the insulating layer and then perform a yellow light process and an etching process to form the insulating layer, so that the partition of each etch area shows a dark color after the insulating layer is etched, and each etched area shows its own pixels, and thus achieving the effect of increasing the readable contrast of the OLED under strong light.
