A distribution density of supports and the spacing therebetween are adjusted to improve a restorability of a light-reflection electrode of a color-changeable pixel. When the spacing between the supports is decreased or the distribution density thereof is increased, a tension per unit area of the light-reflection...http://www.google.de/patents/US20050036095?utm_source=gb-gplus-sharePatent US20050036095 - Color-changeable pixels of an optical interference display panel
