A method of driving an information display device including displaying information of one frame by performing a scanning operation with respect to line electrodes on one substrate and column electrodes on another substrate, such that a voltage is applied to the line electrodes from one end to the other end. Then, a voltage for generating a cross-talk in the first color and a voltage for generating a cross-talk in the second color is applied to all cells one or more times respectively after the one frame is displayed. The information of the one frame is an image, and two or more lines of line electrodes are added at the end of the scanning operation, and a drive, in which a display of the first color and a display of the second color are performed one or more times respectively, is performed after the scanning operation is finished.

Method of driving information display device

In an information display device according to the first to third inventions of the present invention, when a particle movement type information display device of passive matrix drive and dynamic drive is driven, the particle movement type information display device configured to be driven by using a drive circuit having an output stage equivalent circuit capable of outputting only two values of a predetermined drive voltage value and ground level (0V). Moreover, in the forth and fifth inventions of the present invention, in the method for driving the information display device, wherein the display media are sealed between two opposed substrates, at least one of which is transparent, and wherein the display media, to which an electrostatic field is applied, are made to move so as to display information such as an image or the like, electrodes of the information display device are connected to predetermined potential in the driving voltage range with low impedance while information refresh (scan) is not performed.

Method for driving information display device and information display device using the method

A method for directly and accurately estimating friction coefficient of a road surface independently from the slip rate is disclosed. The method measures tangential and vertical forces acting on an elastic bodyof an elastic wheel, and calculates the friction coefficient of a road surface based on the measured values of these forces and angular rate of the wheel
