An electronic eyewear device including a spatial dimming pixel panel within an optical assembly that delivers improved backlighting conditions for displayed images. The spatial dimming pixel panel is spatially dimmed where an image is positioned on a display, and the unoccupied area of the display is not dimmed (undimmed), thereby unaltering the real-world view through that portion of the display. The spatial dimming pixel panel is made of multiple liquid crystal cells arranged in a gridded orientation with a dye-doped or guest-host liquid crystal system having a phase change mode with homeotropic alignment. The spatial dimming pixel panel absorbs nonpolarized light when a voltage is applied across the cells and passes nonpolarized light in the absence of a voltage across the cells.
An electronic eyewear device, comprising:
A method of operating an eyewear device having a display configured to allow viewing of a background through the display, a processor configured to display an image on the display, and a spatial dimming pixel panel having individual pixels coupled to the display, wherein the processor is configured to selectively control dimming of the pixels, comprising the steps of:
A spatial dimming pixel panel configured for use with an electronic eyewear device having a display configured to allow viewing of a background through the display, and a processor configured to display an image on the display, the spatial dimming pixel panel having individual pixels and configured to be coupled to the display, wherein dimming of the pixels is configured to be controlled by the processor, wherein the pixels corresponding to the image are configured to be dimmed while the pixels corresponding to the background are not dimmed.
