Abstract: The present invention discloses a method of fabricating organic light emitting diode array, which adopts a directional spin coating technology to grow different organic light-emitting materials on the same plane so as to control the color of the emitted light and accomplish monochrome or full color organic light emitting diodes.

Abstract: The present invention discloses a method of forming linear patterns, called “directional spin coating” technology. Parallel banks are formed on a substrate to define some trenches; the substrate is vertically erected on outer edge of a spin disc; and a liquid material is applied to the trenches, the spin disc is rotated, and with the centrifugal force of rotation, the material is uniformly coated on the substrate within individual trenches to form a linear pattern. The thickness of the formed pattern is similar to that achievable using the conventional spin-coating approach. The present invention can create linear patterns made of more than one material by selectively coating different materials on specific trenches.
