Abstract
Official abstract text for this publication.
Embodiments of the present invention provide an organic light emitting diode display panel and a method for manufacturing the same. The manufacturing method comprises: coating a photoresist layer on a transparent substrate with an active array formed; performing exposure on the photoresist layer from one side of the transparent substrate opposed to the photoresist layer, where the scan lines and the at least one kind of lines are used as a mask to prevent exposure of the corresponding photoresist, so that a photoresist remaining region is formed by the photoresist layer; conducting a development treatment on the photoresist layer, so that the photoresist outside the photoresist remaining region is removed and the photoresist in the photoresist remaining region is retained to form the pixel defining layer. The embodiments of the invention may simplify the fabricating flow of the display panel, reduce production costs of the display panel, and increase yield of the display panel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a pixel defining layer of an organic light emitting diode display panel, comprising: coating a photoresist layer on a transparent substrate with an active array formed thereon so as to cover the active array, the active array comprising driving power lines, data lines, scan lines, and a plurality of pixel units which are defined by crossing of the scan lines and the data lines, the pixel units comprising first electrodes whic…
