Abstract
A system and method for the automatic color/brightness adjustment of a video display screen, panel, module or other display component comprising light emitting diodes (“LEDs”). The system and method incorporate a reference LED and a light sensor on each module and use decay information sensed from each reference LED to determine the amount of decay experienced by the display LEDs in the modules. Each module will be adjusted to have one uniform color/brightness level based on the decay information sensed from each reference LED.
Claims7
A method of performing automatic color correction of a light emitting video screen comprising a plurality of light emitting modules with display light emitters, said method comprising:
- for each module, inputting a current light level from a reference light emitter on the module;
- for each module, comparing the current light level to a reference level of the reference light emitter to an output level of the module;
- comparing the output levels of the plurality of light emitting modules to determine the lowest light level;
- and
- adjusting the light level of the plurality of light emitting modules such that the display light emitters have the determined lowest light level.
