| Popis: | A novel electronic reflective display using conductive toners and dielectric white particles has been designed and constructed. The display cell consists of two indium−tin oxide (ITO) plates coated with a charge-transport layer (CTL) on the interior of the cell. The toner and white particles are placed in a small space formed by a spacer. In this display, toner movement is controlled by the action of an external electric field applied between the two ITO electrodes. The conductive toners in the vicinity of the CTL on the anode (lower electrode) are charged positively by hole injection from the CTL and then move to the cathode (upper electrode) to form a black image. The toner is held on the CTL of the cathode by an electrostatic force. A white image is formed by applying a reverse electric field that causes the toners to move back to the lower electrode. The reflection densities of the black and white images were determined to be 0.96 and 0.63, respectively. A response time of ca. 0.8 ms was obtained unde... |
