Embodiment Construction

[0040] The invention is a manufacturing method and structure of an organic light-emitting display panel that can improve the bright line problem of the panel caused by the arrangement of non-luminous pixel areas around a specific image on the panel. By reducing the area occupied by the base layer, the area covered by the transparent electrode is reduced, so that part of the cathode conductive material on the non-luminous pixel area will not be completely isolated, but can provide part of the capacitance value when the current passes.

[0041] In this way, the originally low capacitance value of the lines passing through the non-luminous pixel area around the specific image is increased, so that the difference in the capacitance values ​​of the lines on the panel is reduced. As a result, the brightness distribution of the panel is more uniform, and the problem of bright lines is improved.

[0042] The method of the present invention will be described in detail below with a pref...

Abstract

A manufacturing method and structure of the organ light display panel. Use the figure set to reduce the covered area of the transparent electrode in the picture pels area without lighting on the panel, and make the anode and the cathode of the organ light diode respectively connect with the transparent electrode and metal electrode. It still partly has the property of the organ light diode. Change the picture pels area of born electro-property isolated without lighting into the picture area property that can provide the capacitance, when the data circuitry is charged. Therefore it makes the lighting situation of the panel homogeneous, and has efficiently improved the bright line objection of the panel.

Description

technical field [0001] The present invention relates to a method and a structure for manufacturing an organic light emitting display panel, in particular to a method and a structure for improving the bright line problem of the organic light emitting display panel. Background technique [0002] In recent years, in the flat panel display industry, organic light emitting displays (Organic Light Emitting Diode; OLED) have gradually attracted attention due to their advantages such as self-luminescence, high brightness, ultra-wide viewing angle, high response speed, low driving voltage, and light weight. . However, the current market share of organic light emitting displays is still limited. Therefore, major display manufacturers are trying to find the best manufacturing method to improve production yield and product characteristics, hoping to promote organic light emitting displays on the market as soon as possible. achieve popularization. [0003] In the existing organic light...
