Abstract
A method of compensating a left-right gamma difference in a display apparatus using a vision inspection apparatus, which includes sensing sample grayscales displayed on areas defined on a display area of the display apparatus using image sensors of the vision inspection apparatus, estimating intensity values of a left reference boundary at a central area, a left boundary area, a right reference boundary area at the central area and a right boundary area, calculating a first grayscale correction value of the left boundary area such that an intensity estimation value of the left boundary area is substantially equal to an intensity estimation value of the left reference boundary area, and calculating a second grayscale correction value of the right boundary area such that an intensity estimation value of the right boundary area is substantially equal to an intensity estimation value of the right reference boundary area.
