    Abstract: A motion detection device is provided. The motion detection device includes a first dynamic vision sensor (DVS), a memory, a communication circuit, and at least one processor, wherein the at least one processor is configured to receive a plurality of images including a movable object using the first DVS for a predetermined time, generate data for determining a kind of motion of the moveable object based on a motion vector of the plurality of images, transmit the generated data to a cloud, and determine the kind of motion of the moveable object based on information received from the cloud.

    Abstract: Provided are pixel circuits using organic light emitting diodes (OLEDs) and a driving method thereof, and an organic light emitting display including the pixel circuits. The OLED is driven to emit light by a drive transistor generating a drive current compensated with respect to a threshold voltage difference and mobility deviation. The drive transistor may receive reference voltage and data signals in response to separate scan signals supplied to the pixel circuits via different scan lines. As a result, a threshold voltage compensation time, which may include the time during which a reference voltage is supplied to the drive transistor in response to a particular scan signal, may be set long enough regardless of a time during which the data signal is supplied to the pixel circuits located in respective rows of the organic light emitting display in response to a separate scan signal.
