The invention relates to electro-optic displays and methods for driving such displays. The invention provides (i) electrochromic displays with solid charge transport layers; (ii) apparatus and methods for improving the contrast and reducing the cost of electrochromic displays; (iii) apparatus and methods for sealing electrochromic displays from the outside environment and preventing ingress of contaminants into such a display; and (iv) methods for adjusting the driving of electro-optic displays to allow for environmental and operating parameters.
An electrochromic display comprising an electrochromically-active layer comprising a nano-porous-nano-crystalline film comprising a semiconducting metal oxide having an electroactive compound which is either a p-type or n-type redox promoter or p-type or n-type redox chromophore adsorbed thereon or otherwise attached thereto, the display having a solid charge transport layer disposed adjacent said film and in charge transport relationship therewith, the electrochromic display having a plurality of pixels and the charge transport layer being interrupted between adjacent pixels.
An electrochromic display comprising a nano-porous-nano-crystalline film comprising a semiconducting metal oxide having an electroactive compound which is either a p-type or n-type or p-type redox promoter or p-type or n-type redox chromophore adsorbed thereon or otherwise attached thereto, the display having a charge transport material chemically bonded to the promoter or chromophore.
An electrochromic display comprising an electrolyte and an electrochromically-active layer comprising a nano-porous-nano-crystalline film comprising a semiconducting metal oxide having an electroactive compound which is either a p-type or n-type redox promoter or p-type or n-type redox chromophore adsorbed thereon or otherwise attached thereto, the electrolyte having a light scattering or reflective material, or both, dispersed therein the light scattering or reflective material, or both, bearing a coating of a polymer.
An electrochromic display comprising an electrochromically-active layer comprising a nano-porous-nano-crystalline film comprising a semiconducting metal oxide having an electroactive compound which is either a p-type or n-type redox promoter or p-type or n-type redox chromophore adsorbed thereon or otherwise attached thereto, the film having a plurality of optical gaps having a diameter of from about 0.2 to about 0.4 μm formed therein.
An electrochormic display comprising an electrochromically-active layer comprising a nano-poro-nano-crystalline film comprising a semiconducting metal oxide having an electroactive compound which is either a p-type or n-type redox promoter or p-type or n-type redox chromophore adsorbed thereon or otherwise attached thereto, the display having at least one of:
