    Abstract: A display mirror assembly for a vehicle includes an electrochromic cell, a switchable reflective element, a display module, an ambient light sensor, and a controller. The controller automatically selects a display mode or a mirror mode in response to a detected ambient light level. In a display mode, the controller activates the display module, sets the switchable reflective element to a low reflection mode, and sets the electrochromic cell to a clear state with minimum attenuation. In a mirror mode, the controller deactivates the display module, sets the switchable reflective element to a high reflection mode, and varies attenuation by the electrochromic cell.

  • Patent number: 9829740
    Abstract: A display may have a thin-film transistor layer formed from a layer of thin-film transistor circuitry on a substrate, a color filter layer, and a layer of liquid crystal material interposed between the thin-film transistor layer and the color filter layer. The thin-film transistor layer, the liquid crystal layer, and the color filter layer may be sandwiched between upper and lower polarizers. A backlight unit may supply backlight illumination for pixels in the display. The color filter layer may have a black matrix with an array of openings. Color filter elements of different colors may be formed in the openings. The black matrix may have sidewalls that are steep or that are undercut. The profile of the black matrix helps block improperly colored off-axis light and thereby reduces undesired color mixing in the display.
