Abstract: In an organic light emitting diode (OLED) display device and a method for fabricating the same, OLED pixels are patterned through a photolithography process, so a large area patterning can be performed and a fine pitch can be obtained, and an organic compound layer can be protected by forming a buffer layer of a metal oxide on an upper portion of the organic compound layer or patterning the organic compound layer by using a cathode as a mask, improving device efficiency. In addition, among red, green, and blue pixels, two pixels are patterned through a lift-off process and the other remaining one is deposited to be formed without patterning, the process can be simplified and efficiency can be increased.

Abstract: A method of driving an organic light emitting diode display device having first to third sub-pixels and a white sub-pixel comprises judging a gray level of an image data; classifying the image data into a low gray level group, a middle gray level group and a high gray level group; displaying an image using the first to third sub-pixels except the white sub-pixel when the gray level of the image data is classified into the low gray level group; and displaying the image using the first to third sub-pixels and the white sub-pixel when the gray level of the image data is classified into one of the middle and high gray level groups.
