Abstract

A method of implementing global illumination in an organic light emitting diode (OLED) display device utilizing an external shutter to reduce visual artifacts and motion blurring. The display device has a screen for displaying image data and a plurality of pixels each including an organic light-emitting diode. The method includes controlling emission of light from each light emitting diode along a path from the pixel to the screen. The shutter is coupled to the display device and has an on-time state, permitting light to pass therethrough, and an off-time state, blocking light from passing therethrough. The method includes loading image data into the plurality of pixels in raster scan order while the shutter is in the off-time state. The shutter is then switched to the on-time state to simultaneously allow emission of light from each pixel to pass therethrough. During the brief on-time state, image data is simultaneously displayed on the screen for the plurality of pixels thereby displaying the full image all at once.
