Method of Implementing Global Illumination With OLED Displays

摘要

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.

主权项

1. A method of controlling emission of light in a display device which receives image data from a video source, the display device having a screen and comprising a plurality of pixels each including a light emitting element configured to emit light along a path from the pixel to the screen, the steps comprising:
a) providing a shutter disposed on the display device and operated to block emission of light from all pixels during a first portion video frame; b) loading image data into each one of the plurality of pixels and controlling the light emitting element of each pixel based on the image data received during the first portion video frame; and c) simultaneously enabling emission of light from each pixel through the shutter during a second portion video frame.
