Abstract
An overlay for covering the writing surface of an electronic writing tablet includes (a) an LCD touch screen adapted to (i) initially display an image drawn or written upon the upper surface by application of pressure on the upper surface without requiring a transfer of matter to the upper surface and (ii) continue display of the image without the consumption of electrical power; (b) a source of electrical power; and (c) a reversible attaching mechanism for reversibly attaching the LCD touch screen over the writing surface of the writing tablet.
