Full frame uniformity across panels

A method of providing display uniformity in a display apparatus comprises retrieving first calibration data representing display characteristics of a display panel of the display apparatus, the first calibration data representing luminance responses or color responses of both left and right panel regions of the display panel when corresponding pixels of both the left and right panel regions are supplied same input image data; receiving stereoscopic image data comprising left and right image data to be supplied to the left and right panel regions; and modifying the received stereoscopic image data in accordance with the first calibration data to display a stereoscopic image with a substantially same luminance response or substantially same color response in both the left panel region and right panel region when the first calibration data indicates discrepancy between the luminance response or color responses between corresponding pixels of the left and right panel regions.
