US 2024/0206227 A1 · ACTIVE MATRIX DISPLAY, SYSTEM, AND METHOD

Abstract

An active matrix display is disclosed that includes a plurality of pixel circuits. Each of the pixel circuits includes a light-emitting element, at least two transistors, and a storage capacitor. An additional transistor is provided, which is configured for discharging of the storage capacitor. An active matrix display is also disclosed, having at least two drive circuits, wherein at least one of the pixel circuits is driven by a data driver of a first drive circuit is residing physically within a second drive circuit, or vice versa. Further, an active matrix is disclosed, wherein the timing of scan signals and updating of data signals is programmed in relation to the operation of a camera recording an image that is displayed on the active matrix display.
