Abstract: Methods and apparatus provide for a display device comprising a plurality of display panels arranged adjacent to one another along the respective peripheral edges thereof, and wherein respective first and second viewing planes form an obtuse angle T relative to each other. The display device further includes a cover sheet located in proximity to, and covering the first and second viewing planes, and includes a light compensation portion located proximate to the peripheral edges of the first and second flat panel displays, and has a curvature complementary to the obtuse angle between the respective first and second viewing planes. The light compensation portion bends light produced by respective peripheral areas of the first and second flat panel displays proximate to the respective peripheral edges thereof to reduce visual discontinuities introduced by the peripheral edges into an image displayed on the first and second flat panel displays.
