Abstract:
1. A display apparatus comprising: a frame rate converter configured to divide an image signal into a first image frame for a left eye and a second image frame for a right eye, and to generate a first intermediate image frame and a second intermediate image frame, which are successive to the first image frame and the second image frame respectively, so as to convert the image signal to a quad-speed image signal; a timing controller configured to generate a first compensation frame and a second compensation frame from the first image frame and second image frame respectively, and to sequentially output the first compensation frame, the first intermediate image frame, the second compensation frame, and the second intermediate image frame; a data driver configured to convert the first compensation frame and the second compensation frame to a left-eye data voltage and a right-eye data voltage, respectively, to convert the first and second intermediate image frames to a black data voltage corresponding to a predetermined black gray-scale in response to a black insertion control signal, and to invert a polarity of the left-eye data voltage and the right-eye data voltage every 4n frames (where n is a natural number equal to or larger than 1) in response to an inversion signal; a display panel that sequentially receives the left-eye data voltage, the black data voltage, the right-eye data voltage, and the black data voltage to display a left-eye image and a right-eye image in an alternating manner; and a gamma voltage generator configured to provide a gamma reference voltage to the data driver, wherein the data driver converts the first compensation frame to the left-eye data voltage and the second compensation frame to the right-eye data voltage based on the gamma reference voltage.
