Abstract:
A substrate comprising: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 an 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 applying a voltage to the electrode within 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 storing the signal of the (Nâˆ’1)-th image within the first duration of time, and when a signal of an (N+2)-th image is applied to the signal electrode, the pixel drive circuit applying a voltage to the electrode within 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 storing the signal of the (N+2)-th image within the second duration of time, N being a natural number.
