Patent ID: 7079093

Claim:
An organic light emitting diode (OLED) display, comprising: a plurality of data lines; a plurality of scan lines perpendicular to the data lines, wherein the scan lines and the data lines define a plurality of pixels, each of the pixels has a pixel area and the aligned pixel areas form a plurality of pixel area arrays parallel to the scan lines or the data lines; a plurality of spaced catbode electrodes parallel to the scan lines or the data lines and each of the spaced cathode electrodes covering one of the pixel area arrays; and a metal layer surrounding the plurality of pixel area arrays, for being partially covered by the plurality of spaced cathode electrodes, wherein the plurality of spaced cathode electrodes are coupled to the metal layer through contact holes outside of the pixel area arrays, wherein there is a space between each two of said cathode electrodes and said space is above the scan lines or the data lines so that the spaced cathode electrodes uncover the scan lines or the data lines.
