Abstract: A dual release actuator for a vehicle seat includes a motor, a cable carrier configured to receive power of the motor, thereby rotating to selectively pull one of two different cables, a Hall sensor to sense rotation of the motor, and a controller configured to count a sensing pulse of the Hall sensor for controlling rotation of the motor.

Abstract: A display device includes a substrate, a first conductive layer on the substrate, the first conductive layer including a data signal line, a first insulating layer on the first conductive layer, a semiconductor layer on the first insulating layer, the semiconductor layer including a first semiconductor pattern, a second insulating layer on the semiconductor layer, and a second conductive layer on the second insulating layer, the second conductive layer including a gate electrode disposed to overlap the first semiconductor pattern, a transistor first electrode disposed to overlap a part of the first semiconductor pattern, wherein the transistor first electrode is electrically connected to the data signal line through a contact hole that penetrates the first and second insulating layers, and a transistor second electrode disposed to overlap another part of the first semiconductor pattern.

Abstract: A lamp driving device includes first, second, and third voltage converters. The first voltage converter converts a direct current (DC) power voltage to a first pulse voltage. The second voltage converter converts the DC power voltage to a second pulse voltage. The third voltage converter generates a high alternating current (AC) voltage based on the first and second pulse voltages. The lamp driving device generates the high AC voltage without a transformer, so that a manufacturing cost of a display apparatus adopting the lamp driving device may be reduced.
