1. A method for manufacturing an organic light emitting diode device, including:
providing a substrate,
providing a green light emitting element on the substrate,
forming a green color resist film layer on a light exit side of the green light emitting element;
forming a green color film layer from the green color resist film layer, by adjusting an irradiation time of exposure light irradiated to the green color resist film layer using a digital gray scale adjustment method;
wherein a travel distance of a light emitted from the green light emitting element in the green color film layer remains substantially unchanged with change of a light exit angle of the light, wherein the green light emitting element is a point light-emitting light source, the travel distance refers to a distance that the light entering from a projection center of the green color film layer on the substrate and emitted by the point light emitting light source travels in the green color film layer when leaving the green color film layer, and the light exit angle refers to an angle between a propagating direction of the light emitted from the point light-emitting light source in the green color film layer and a direction perpendicular to a surface of the organic light emitting diode device, and
wherein the light emitted by the point light emitting light source enters the green color film layer from the projection center of the green color film layer on the substrate and is deflected at the light exit angle to exit through the green color film layer,
wherein an area of the green color resist film layer corresponding to the green light emitting element is a first area; and
the green color resist film layer uses negative photoresist, and an irradiation time of exposure light irradiated to a peripheral edge portion of the first area is less than an irradiation time of exposure light irradiated to a middle portion of the first area.
