Abstract
Liquid Crystal Display (LCD) flare is reduced by adjusting a backlight to a level where the LCD flare is not visible, and then introducing a simulated veiling glare. The glare is further adjusted by the backlight simulation to hide the geometry (e.g., Light Emitting Diode (LED) array) of the backlight. The reduction is performed, for example, by processing signals for driving the backlight and a front modulator in a dual modulation display device.
