Abstract
The present invention relates to an area-efficient apparatus and method for sensing a signal using overlap sampling time. In a preferred embodiment of the present invention, the sensing apparatus sensing a signal which detects degradation of a light-emitting device and transferring the signal to a compensating circuit comprises: M switching portions connected to sensing lines included in each group of M groups into which N sensing lines are divided, where N>M and N and M are natural numbers. The switching portion is characterized by alternatively connecting any one of N/M sensing lines to a sample-and-hold portion.
