Abstract

The invention discloses a Micro OLED display and a production method thereof. The production method comprises the following steps: producing a CMOS drive circuit on a silicon wafer substrate to obtain a substrate, and producing an AMOLED light-emitting layer on the substrate according to a pixel arrangement structure; preparing an inorganic and organic superposed packaging layer on the AMOLED light emitting layer; preparing an organic planarization layer on the packaging layer in an ink-jet printing mode; and carrying out RGB coating on an organic buffer layer to form a color filter layer. The organic layer and the organic planarization layer are prepared in an ink-jet printing mode, the organic planarization layer and the organic layer can be manufactured as required, the organic planarization layer is prepared from a specific material, the problems that spin coating of the organic layer and the organic planarization layer is not uniform and the organic planarization layer is not matched with the packaging layer are solved, the working procedures are reduced, and the device performance is improved.
