Abstract
There is disclosed an automatic electronic window shading (tinting) system for houses and transport vehicles such as automobiles, RV's, trains, boats and the like, to provide shading for people to protect them from exposure to harmful direct sunlight, by providing the windows of said houses and transport vehicles with display elements and light (photocell/photovoltaic) sensors. The system comprises liquid crystal, electrochromic, suspended particle device (SPD), or NanoChromics display (NCD) element attached to a part of a transparent body (such as the windows) and a liquid crystal, electrochromic, suspended particle device (SPD), or NanoChromics display (NCD) controlling semiconductor element controlling the operation of the display element.
