DISPLAY DEVICE BASED ON THE LED AND A METHOD OF CORRECTING ITS BRIGHTNESS Russian patent published in 2020 - IPC G09G3/32 

FIELD: computer equipment.

SUBSTANCE: display device includes a display unit, which includes a display module, which includes a plurality of LED elements, first temperature recording unit, first and second aging display units, including LED measuring element, equivalent to LED elements, brightness measurement unit, a second temperature recording unit, a luminescence accumulation time storage unit, a brightness reduction degree storage unit, where the relationship between the accumulated luminescence time of the LED measuring elements and the degree of dimming of the LED measuring elements is stored, and the luminance correction coefficient calculating unit, wherein the luminance correction coefficient calculating unit corrects the luminance correction factor based on the temperatures detected by the first and second temperature recording units.

EFFECT: technical result consists in counteracting image quality degradation due to change of characteristics of each LED element and method of its brightness correction.
