Abstract: A pixel circuit includes a driving circuit, a lighting element, and multiple switching circuits. The driving circuit is configured to provide a driving current to a first node. A first terminal of the lighting element is coupled with a second node. A second terminal of the lighting element is configured to receive a system low voltage. The multiple switching circuits are coupled between the first node and the second node in a parallel connection, and configured to correspondingly receive multiple emission control signals and at least one grayscale control signal. During each frame, the multiple emission control signals provide multiple pulses, and the multiple pulses do not mutually overlapping in time sequence, so that the multiple switching circuits selectively couple the first node to the second node according to the multiple pulses and the at least one grayscale control signal.

Abstract: The disclosure provides a display panel including first pixel structures, second pixel structures, first signal lines, second signal lines, a first driving circuit, and a second driving circuit. The first signal lines and the first pixel structures are disposed in a first display area and electrically connected. The second signal lines and the second pixel structures are disposed in a second display area and electrically connected. The first display area and the second display area are arranged in a first direction. The first signal lines and the second signal lines are arranged in a second direction. The first direction and the second direction are perpendicular. The first signal lines and the second signal lines are structurally separated. The first drive circuit is electrically connected to the first signal lines. The second driving circuit is electrically independent from the first driving circuit and electrically connected to the second signal lines.

Abstract: A display device including a first substrate, pixel structures, a second substrate, first signal lines, and second signal lines is provided. The pixel structures are disposed on a first surface of the first substrate. Each of the pixel structures includes a switch element and a pixel electrode. The switch element has a first terminal, a second terminal, and a control terminal. The pixel electrode is electrically connected to the second terminal of the switch element. The second substrate is disposed under a second surface of the first substrate. The first signal lines and the second signal lines are disposed on the second substrate. The first terminals and the control terminals of the switch elements of the pixel structures are respectively electrically connected to the first signal lines and the second signal lines, wherein the first signal lines are substantially parallel to the second signal lines.
