Abstract: Systems, devices, and methods for detecting ambient light with wearable heads-up displays are described. An ambient light sensor can be positioned close to a user's eye area on a user-side of a wearable heads-up display. By positioning the ambient light sensor on a user-side of the wearable heads up display, the ambient light sensor can be in a position and/or orientation which receives ambient light in a similar manner a user's eye, and thus ambient light detection can be more accurate. Brightness of display light output by the wearable heads-up display can be adjusted in response to the detected brightness of ambient light.

Abstract: An electroluminescent display and driving method is provided wherein the rows of pixels are divided into sub-pixel sets and several different sets of sub-pixels are then addressed from within a larger superset of adjacent sub-pixels. The image data for the addressed sub-pixels is averaged with that for adjacent sub-pixels and is applied to the reduced number of larger sub-pixels in sequence. Consequently, for a given sequence of input frame data sets the time average over one frame for a portion of the sub-pixels at any location of the panel is substantially the same as that for a conventionally addressed sub-pixel in a prior art panel.
