Organic layer and method of manufacturing the same, directional heat source assembly, and display panel

A method of manufacturing an organic layer, the method comprising:

• forming an organic material solution layer on a substrate;
• and
• heating, by a directional heat source assembly, at least a first portion of organic material solution of the organic material solution layer that is inside a pending area of the substrate and a second portion of the organic material solution of the organic material solution layer that is outside the pending area of the substrate, a heating efficiency of the directional heat source assembly to the first portion of the organic material solution being greater than a heating efficiency of the directional heat source assembly to the second portion of the organic material solution, to increase an evaporation rate of the first portion of the organic material solution,
• whereby, a thickness difference of the organic layer that is cured from the organic material solution layer is reduced, due to different evaporation rates of the first portion of the organic material solution and the second portion of the organic material solution;
• wherein the directional heat source assembly comprises a planar directional heat source configured to generate heat radiation, and a mask comprising a shielding part configured to shield the heat radiation from the planar directional heat source and at least an opening part having an adjustable size and configured to pass the heat radiation from the planar directional heat source therethrough;
• and
• wherein the heating at least a first portion of organic material solution of the organic material solution layer further comprises:
• aligning the mask with the substrate so that the opening part of the mask is aligned with the pending area of the substrate;
• and
• heating, by the planar directional heat source, the first portion of the organic material solution of the organic material solution layer through the opening part of the mask.
