Organic electroluminescent display (OLED), manufacturing method thereof and display device

The invention discloses an organic electroluminescent display (OLED), a manufacturing method of the organic electroluminescent display (OLED) and a display device. A pixel defining layer arranged in the organic electroluminescent display (OLED) is provided with opening areas corresponding to pixel areas of the OLED, an opening of each opening area is larger than the bottom face of the opening area, and thus the problem that a cathode may break later can be avoided; because the upper surface of the pixel defining layer is made from lyophobic material, and luminescent material with which the pixel defining layer is coated later cannot remain on the upper surface of the pixel defining layer easily, the problem that colors of the adjacent pixel areas are mixed can be avoided; meanwhile, the inclined faces of the corresponding opening areas of the pixel defining layer are made from lyophilic material so that it can be guaranteed that the opening areas are evenly filled with the luminescent material with which the pixel defining layer is coated later. Therefore, according to the OLED, the uniformity of a film layer formed later on the pixel defining layer can be guaranteed, and the luminescence property of the OLED is improved.

Pressure extrusion method for filling features in the fabrication of electronic devices

InactiveUS20090226603A1More consistentReduce structureElectrical apparatusCoatingsAspect ratioPhase-change material
A method of filling high aspect ratio features with active electronic or conductive materials. In one method, high pressure extrusion is used to urge the as-deposited active or conductive material into an incompletely filled opening. In another method, a rapid thermal anneal process is used to induce reflow of the as-deposited active or conductive material into an incompletely filled opening. Both methods are also effective in densifying active or conductive materials within openings by collapsing voids that arise in the as-deposited state. The instant methods provide for more uniform and consistent filling of openings and minimize the variability and impairment of electrical characteristics of active material devices. Active materials include phase-change materials, chalcogenide materials, switching materials, and programmable resistance materials.
