Abstract
The self-lighting subpixels of a display device are ones whose output luminances are functions of analog drive voltages applied to the subpixels and corresponding digital grayscale command signals used for controlling the subpixels. The display device generates corresponding analog dimming values and digital dimming values in accordance with supplied current limiting parameters and generates control value signals using the analog dimming values and the digital dimming values. It also changes the original grayscale digital data values of input video signals of one frame in accordance with the digital dimming values.
