Abstract
A display comprises spaced first and second electrodes, and a plurality of electrochromic nanoparticles disposed between the electrodes, each of the nanoparticles having an electron-rich state and an electron-depleted state, the two states differing in at least one optical characteristic. Upon injection of charge from one of the electrodes, the nanoparticles switch between their electron-rich and electron-depleted states, thus changing an optical characteristic of the display.

a display comprising:
- first and second electrodes spaced from one another;
- and
- a plurality of electrochromic nanoparticles disposed between the first and second electrodes, each of the nanoparticles having an electron-rich state and an electron-depleted state, the two states differing in at least one optical characteristic, such that injection of charge from at least one of the first and second electrodes will cause at least some of the nanoparticles to switch between their electron-rich and electron-depleted states.
A method for operating a display, the method comprising:
- providing first and second electrodes spaced from one another;
- providing a plurality of electrochromic nanoparticles disposed between the first and second electrodes, each of the nanoparticles having an electron-rich state and an electron-depleted state, the two states differing in at least one optical characteristic;
- and
- injecting charge from at least one of the first and second electrodes into the nanoparticles, and thereby causing at least some of the nanoparticles to switch between their electron-rich and electron-depleted states, thus changing an optical characteristic of the display.
