DISPLAY DEVICE AND IMAGE SIGNAL PROCESSING METHOD Russian patent published in 2013 - IPC G09G3/30 

FIELD: information technology.

SUBSTANCE: device has an average brightness calculator, an average brightness selector and a lighting time setting device which sets the effective filling coefficient depending on the average brightness value, wherein said coefficient controls the lighting time for each frame during which a luminous element lights up, wherein said setting device sets the efficient filling coefficient such that the amount of light controlled based on a given reference filling coefficient and the possible maximum brightness of the image signal is equal to the amount of light controlled based on the set effective filling coefficient and the average brightness value.

EFFECT: preventing flow of excess current to luminous elements of the display.
