Abstract: Provided is an apparatus and method of measuring a pulse wave. The method includes: causing receivers to respectively receive pulse wave signals that are detected at two points of an object, determining an effective pulse wave signal period by using the received pulse wave signals, and obtaining a pulse transit time (PTT) between the two points by using a result obtained after comparing a magnitude of an output signal of each of the receivers with a value that is less by a predetermined percentage than a peak value of an output signal of each of the receivers during the determined effective pulse wave signal period.

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.

Abstract: Provided are a Raman signal measuring method and apparatus which use a difference in a time scale between Raman scattered light and fluorescence. Thus, after exciting light is incident upon a target object, light scattered from the target object may be detected before the target object generates fluorescence in response to the exciting light. As a result, a Raman signal in which background fluorescence is reduced may be obtained.
