Abstract: An electronic device includes a display having a memory function and a communications capability. Display functions are controlled based on a state of the operation of the device and/or based on a state of received data. Also disclosed is a method of selectively displaying advertising information based on a state of the device where the advertising can be maintained on the display without requiring any power consumption.

Abstract: A matrix driving method for liquid crystal display having liquid crystal which exhibits cholesteric phase and capability of keeping image displayed after turn-off of electric field applied by using scan electrodes and data electrodes arranged to face and cross each other with the liquid crystal in between, includes applying reset pulse to reset liquid crystal to homeotropic state, selecting final state of liquid crystal, and stabilizing liquid crystal to selected state. The selection step includes, in order named, a first time of applying substantially 0 volt to liquid crystal, a second time of applying selection pulse to select final state of liquid crystal, and a third time of applying substantially 0 volt to liquid crystal. In first or second time, a compensation pulse may be applied to liquid crystal in form determined depending on temperature or so that a plurality of liquid crystal layers will have same scanning speed.

Abstract: Disclosed is a liquid crystal display apparatus comprising: a liquid crystal display element having a plurality of liquid crystal layers each having a plurality of display units that are arranged in a matrix fashion and are defined by intersections of a plurality of scanning line electrodes and a plurality of data line electrodes, said liquid crystal layers being stacked each other such that said scanning line electrodes and said data line electrodes of any one of said liquid crystal layers match said scanning line electrodes and said data line electrodes of the other ones of said liquid crystal layers whereby a plurality pixels are formed by the display units of each liquid crystal layer that overlap with each other; and a controller for, when an image is drawn in said liquid crystal display element, selecting at least one of the matching scanning line electrodes of said liquid crystal layers at a different timing than that used for the other matching scanning line electrodes, such that the all of the matchi

Abstract: A matrix driving method for a liquid crystal display which has liquid crystal which exhibits a cholesteric phase and is capable of keeping an image displayed thereon after turn-off of an electric field applied thereto by using a plurality of scan electrodes and a plurality of data electrodes which are arranged to face and cross each other with the liquid crystal in-between. The method has a reset step of applying a reset pulse to reset the liquid crystal to a homeotropic state, a selection step of selecting the final state of the liquid crystal, and an evolution step of stabilizing the liquid crystal to the selected state. The selection step has a first step including a time of applying substantially 0 volt to the liquid crystal, a second step of applying a selection pulse to select the final state of the liquid crystal and a third step, after the second step, including a time of applying substantially 0 volt to the liquid crystal.
