APPARATUS, METHOD AND MODULE FOR SELECTIVE PIXEL CONTROL OF DISPLAY

摘要

An apparatus including: a pixellated polarizer comprising a first array of pixels wherein each pixel can be selectively controlled either to provide a defined polarization or not to provide a defined polarization; a pixellated light emitter comprising a second array of pixels wherein each pixel can be selectively controlled to emit light; a reflector; and a controller configured to control the pixellated polarizer and pixellated light emitter to adopt in a first context a transmissive mode, in a second context a reflective mode and in a third context a selective transflective mode. In the transmissive mode, pixels of the pixellated light emitter are selectively controlled to emit light and the pixels of the pixellated polarizer are unselectively controlled to provide the defined polarization. In the reflective mode pixels of the pixellated light emitter are controlled not to emit light and the pixels of the pixellated polarizer are controlled to selectively provide the defined polarization. In the selective transflective mode pixels of the pixellated light emitter are selectively controlled to emit light and the pixels of the pixellated polarizer are controlled to selectively provide a defined polarization.
