摘要

A liquid crystal device includes, peripheral electrodes including three electrodes for ion trapping, and a transistor coupled to each of the three electrodes. A common signal (COM signal) that varies between a first potential and a second potential in a first period is applied to a counter electrode. A driving signal that varies between a third potential and a fourth potential is input to the transistor. The driving signal is coupled to or uncoupled from the peripheral electrodes by the transistor in a unit of a duration equal to or less than ? of the first period. AC signals varying between a positive-polarity potential and a negative-polarity potential, with a potential of the common signal being a reference, in a second period longer than the first period, are applied to the three electrodes of the peripheral electrodes, in a state where phases of the AC signals are shifted mutually.

說明書

In the above-described driving method for a liquid crystal device, the switching element is preferably in a coupled state in all or part of a first duration in the common signal is at the first potential and the AC signals are at a negative-polarity potential, or a second period in which the common signal is at the second potential and the AC signals are at a positive-polarity potential, the switching element being preferably in an uncoupled state in a duration other than the first duration, and when the common signal is in the first duration and the switching element is in a coupled state, the driving signal is preferably at the fourth potential, and when the common signal is in the second duration and the switching element is in the coupled state, the driving signal is preferably at the third potential.

In the above-described driving method for a liquid crystal device, the liquid crystal device preferably includes three electrodes configured for ion trapping, an average of the second periods of the AC signal is preferably an integral multiple (n times) of 6 of the first period of the common signal, and the AC signals repeating a period of n×(6+1) and a period of n×(6?1) is preferably applied to the three electrodes.

An electronic apparatus according to an aspect of the disclosure includes the above-described liquid crystal device.
