Abstract
A display device and a luminance control method therefore are provided. The display device comprises a luminance controller that establishes multiple peak luminance control (PLC) points by equally dividing a PLC curve and limits the luminance at the PLC point corresponding to the highest average pixel level (APL) at the initial luminance as the PLC curve slopes downward.
