Abstract: A display apparatus includes a first transistor including a first semiconductor layer and a first electrode that at least partially overlaps the first semiconductor layer. A first capacitor includes the first electrode and a second electrode that at least partially overlaps the first electrode. A second capacitor includes the second electrode and a third electrode that at least partially overlaps the second electrode. A first data line is configured to transfer a data voltage therethrough. First and second scan lines are configured to transfer first and second scan signals therethrough, respectively. A second transistor connects the first data line to the second electrode in response to the first scan signal. A third transistor connects the first electrode to a drain of the first transistor in response to the second scan signal.

Abstract: A corrugated paper display stacker having a plurality of vertically arranged springs and upwardly biased pivoted trays secured to a back panel. A double acting torsion spring having hooks on protruding fingers that are inserted into the fluting of the tray and a stablizing U-shape loop on the other side of the spring maintain each of the trays in a vertical position when not loaded with merchandise. The torsion spring is held to the back panel by securing means in the form of a dowel.
