Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for improving quality (e.g., eliminating parallax and/or increasing contrast) of an observed image in displays (e.g., transflective displays) in a reflective mode by creating at least one complimentary image based on measurements of ambient light luminance and/or diffusivity as well as minimizing the power necessary to achieve readability in low ambient light. In one embodiment the parallax (shadow) image may be inverted and displayed on the emissive display to cancel the parallax image. In another embodiment an improvement of readability (e.g., thus improving contrast) of a positive polarity text/graphic image on the LCD may be accomplished by using an inverted blurred version of the same image multiplied with the original image.

Abstract: An apparatus including: a pixellated polarizer including 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 including 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.
