Abstract
A device for bonding a fingerprint sensor to a display panel including a picker for securing a rear surface of a fingerprint sensing unit with a first planar surface having a (1-1)-th inclination, a stage for securing a front surface of the display panel with a second planar surface having a (2-1)-th inclination, distance measuring units for measuring distances to first points on a front surface of the fingerprint sensing unit and to second points on a rear surface of the display panel, a controller outputting a control signal that adjusts an inclination of the first planar surface or the second planar surface, an inclination adjusting unit for adjusting an inclination of the first and planar surfaces, and a vertical driving unit for moving at least one of the first and second planar surfaces along a first direction to bond the fingerprint sensing unit to the display panel.
