Abstract:
A display apparatus includes: a display panel configured to display an image; a fingerprint sensor disposed on the display panel and configured to capture a fingerprint image and to generate fingerprint sensing data; and a fingerprint sensor controller configured to generate a compensation characteristic function of each pixel of the fingerprint sensor using a plurality of test patterns, to extract a coefficient of the compensation characteristic function of each pixel and to compensate the fingerprint sensing data using the coefficient of the compensation characteristic function.
