摘要： A method of making a gyricon display device, and a method of determining a monopole charge and a dipole charge of beads in a gyricon display device, is set forth. In the methods, a rectangular waveform switching voltage is applied to the gyricon display device and the reflectance of the display device is measured in order to determine the dipole charge based upon the measured reflectance, and a triangular waveform switching voltage is applied to the gyricon display device and current of the display device is measured to determine the monopole charge based upon the measured current.

摘要： Toner particles and a dry-powder electrophoretic display employing such particles are disclosed herein. The toner particles adapted for a dry-powder electrophoretic display comprise emulsion/aggregation particles having a negative charge. At least a portion of the toner particles include a surface coating, comprising a methacrylate polymer, disposed on the surface of the toner particles to impart a positive charge to a set of toner particles. The emulsion/aggregation toner particles have a particle size generally less than about 10 micrometers that allows for improved image quality as compared to conventional toners utilized in dry-powder electrophoretic displays.
