摘要: An EL device has a transparent substrate, regulating and plurality of components disposed over the substrate. Each component includes an pixel photo detector. pixels anode layer, light emitting layer cathode layer. The photo-detector is connected to between substrate pixel, adopted for converting portion luminance emitted from into signal. A current corresponding regulated according decay first signal so that combined CIE value lights all satisfies predetermined set value.
