Abstract

The invention provides an organic light-emitting diode display. A contact hole is formed in a negative electrode isolation post, a negative electrode is formed on an auxiliary electrode in the contacthole, the negative electrode in the contact hole is electrically connected with the auxiliary electrode, the negative electrode in the contact hole is connected with a negative electrode outside thenegative electrode isolation post by a third opening in a side surface of the negative electrode isolation post, the problem of resistance drop of the negative electrode in a large-size display panelis solved, and the problem that light-emitting brightness of a large-size top light-emitting display panel is affected due to large resistance drop of the negative electrode is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an organic light emitting diode display. Background technique [0002] Currently, Organic Light Emitting Diode (OLED) displays include top emission (Top Emission), bottom emission (Bottom Emission) and transparent display (Transparent Display) and other light emitting methods. Among them, the top-emitting OLED display has the advantages of high resolution and large light-emitting area, and is widely used in small-sized OLED display panels. Since large-size display panels tend to increase resolution, top-emission display panels have become an important research direction for large-size display panels. When the top-emitting display panel is manufactured as a large-size display panel, the cathode material is required to be transparent and the thickness of the cathode should not be too large, so as to ensure the light output rate of the OLED display panel. Due to the thi...
