Abstract

A substrate for an electrooptical device includes a signal electrode, a first sample-and-hold circuit electrically coupled to the signal electrode, a second sample-and-hold circuit electrically coupled to the signal electrode, a pixel drive circuit, and a pixel electrode electrically coupled to the pixel drive circuit. When a signal of an (N+1)-th image is applied to the signal electrode, the pixel drive circuit applies a voltage to the pixel electrode during a first duration of time in response to a signal of an N-th image stored in the first sample-and-hold circuit, and the second sample-and-hold circuit stores the signal of the (N+1)-th image within the first duration of time. When a signal of an (N+2)-th image is applied to the signal electrode, the pixel drive circuit applies a voltage to the pixel electrode during a second duration of time in response to the signal of the (N+1)-th image stored in the second sample-and-hold circuit and the first sample-and-hold circuit stores the signal of the (N+2)-th image within the second duration of time, and N is a natural number.
