Abstract
Unevenness detecting apparatus for compensating for threshold voltage and method thereof is provided with a plurality of scan lines and a plurality of data lines and a pixel circuit arranged in each point which the scan lines and the data lines are intersected. The unevenness detecting apparatus for compensating for the threshold voltage and method thereof may accurately sense a state of minute unevenness such as fingerprints by using an active element (e.g., TFT) as an element of which pixel circuit is composed.
