Embodiment Construction

[0031] According to a preferred embodiment of the present invention, it discloses a method for reducing the voltage drop effect caused by metal wires in an organic electroluminescence display device. The method includes providing an improved metal wire structure, so that the cross-sectional area of ​​the conductive part of the metal wire structure is increased, thereby reducing the resistance value of the metal wire structure. The design of the improved metal wire structure does not need to change the original effective width and line distance of the metal wire, therefore, it does not need to change the layout and size of the connecting lines in the organic electroluminescent display device. In order to simplify the illustration, only a metal wire with a single-layer structure is used as an example for illustration below. However, the metal wire with a single-layer structure is only an example of the present invention. The improved metal wire structure and method described in ...

Abstract

The invention discloses a conduction unit used in an organic electroluminescence display device. The conducting unit includes one or more non-conducting base lines and one or more conducting lines formed on the non-conducting base lines, and the non-conducting base lines are formed on a predetermined position of a substrate. Wherein, the non-conductive base line increases the height of the conductive line formed thereon to increase the cross-sectional area of ​​the conductive line, thereby reducing the resistance of the conductive unit.

Description

technical field [0001] The invention relates to an organic electroluminescence display device, in particular to the design of the metal wire structure of the organic electroluminescence display device. Background technique [0002] A typical organic electroluminescence display device includes a plurality of organic light emitting diode pixels, and the plurality of organic light emitting diode pixels are electrically connected and arranged into a matrix array. In addition to a switching and a driving circuit, each organic light emitting diode pixel further includes a capacitor and a thin film transistor connected with the scanning line, the data line and the power line. The above circuit configuration is used to provide image display signal and power to the OLED pixel. The image display signal is sent to the organic light emitting diode pixel matrix array through the scanning line, data line and power line connected with the organic light emitting diode pixel circuit.
