Embodiment Construction

[0022] Embodiments of the present invention will cooperate with Figures 1 to Figure 7 The cross-sectional flow chart is described in detail as follows. As shown in Figure 1, first provide a transparent substrate 10, this transparent substrate 10 can be a transparent glass substrate or a transparent plastic substrate, if it is a plastic substrate, its material can be polyethylene terephthalate (polyethyleneterephthalate), polyester ester (polyester), polycarbonate (polycarbonates), polyacrylate (polyacrylates) or polystyrene (polystyrene). A buffer layer can also be formed on the transparent substrate, such as a composite buffer layer composed of a silicon nitride layer and a silicon oxide layer, so as to improve the adhesion between the subsequent film layer and the transparent substrate 10 and improve transparency. The roughness of the surface of the substrate 10. Next, an active layer is formed on the transparent substrate 10, such as a polysilicon layer or an amorphous si...

Abstract

This invention is a method to make an organic electroluminescence structure used in making a unit of electroluminescence on some big display plates or windows. This procedure contains: Providing a transparent base plate to form a film transistor, one of its wire on the face of transistor, another on its side and be connected on the power or open pole. The later extend to transparent film base plate, to form a transparent electro-pole on the base plate, and then the organic luminous diode is formed.

Description

technical field [0001] The present invention relates to a method for manufacturing an organic electroluminescent display device, in particular to a method for manufacturing an active matrix organic electroluminescent display device using less manufacturing process photomasks, so as to reduce manufacturing time and save production cost. Background technique [0002] In the new generation of flat-panel display technology, organic electroluminescence display (organic electroluminescence display) is a thin-film laminate display that uses organic compounds as light-emitting materials. The manufacturing process is simple and the like, and the main luminescent principle is to use an organic luminescent layer composed of dye or polymer between the cathode (cathode) and the anode (anode) to emit light. [0003] According to the driving method of the organic electroluminescent display, it can generally be divided into two types: a passive matrix type and an active matrix type. The a...
