Abstract: A method for driving an active matrix organic light-emitting diode (AMOLED) display. The method may be used to digitally drive the AMOLED display in a way that limits the susceptibility of the AMOLED display to certain problems arising out of digital driving techniques, such as image sticking or low display lifetimes. The method involves generating compensation factors corresponding to each pixel of the display and using those compensation factors to control the illumination of the display. The aspects of the method that incorporate the operation point for generating a compensation factor may also be applied to analog driving of AMOLED displays.

Abstract: The present disclosure describes systems and methods that enable eye-tracking by steering a light signal in a high-density Lissajous pattern over a region of an eye and detecting light reflected from the eye using a non-imaging photodetector configuration. The light signal is scanned by driving each axis of a two-axis MEMS scanner with a periodic signal having a frequency that is based on the resonant frequency of that axis. By choosing periodic signals having frequencies that give rise to precession of the Lissajous pattern at a high rate, a high-density scan pattern is quickly generated, thereby enabling eye tracking with high spatial resolution and low latency.

Abstract: A display device is operated by using several iterations of a scan phase followed by a global drive phase. In the scan phase, the state of each pixel in the display device is set to either “enabled” or “disabled”, during which time a global drive generator is inactive. Then, in the global drive phase, a global drive signal is sent to the display device. Only the subset of enabled pixels is affected by the global drive signal, which causes the enabled pixels to perform a transition to a desired display state. The sequence of the scan phase followed by the global drive phase is then repeated up to the number of unique transitions required to update the display device.
