Abstract: A luminance difference correction method and a light emitting display apparatus using the same is discussed. The luminance difference correction method can include receiving by an camera an image, which is output from a camera region of a light emitting display panel and is reflected by at least one of a reflector or a cover glass associated with the apparatus. The method can further include analyzing by a controller the image received by the camera, and varying a level of at least one of (i) a gamma voltage used to generate a data voltage to be output to data lines included in the light emitting display panel, and (ii) one or more of driving voltages supplied to pixels included in the light emitting display panel.
