Abstract:
1. A method for generating an uniform luminosity for displaying contents on an organic light emitting diode display device that include a plurality of pictures and a plurality of pixels, the organic light emitting diode display device having a driver chip to light the pictures and the pixels, the method comprising steps of: setting a unit time which is the time of the driver chip to scan each of the pixels; calculating a ratio of an area of each of the pictures and an area of one pixel; obtaining maximum ratio from the ratio of the pictures, providing simultaneously a first scanning signal by the driver chip to each of the pictures based on the maximum ratio, the first scanning signal being provided for a first period of time, the first period of time being a multiplication of the unit time and the maximum ratio; and providing respectively a first current signal to each of the pictures by the driver chip based on the ratio of each of the pictures when the driver chip simultaneously provides the first scanning signal to each of the pictures, each of the first current signals being providing a second period of time, the second period of time being a multiplication of the unit time and the ratio of each of the pictures.
