1. A light emitting display unit, comprising:
a pixel module comprising a first LED for emitting a first color of light, a second LED for emitting a second color of light, and a third LED for emitting a third color of light, wherein the first, second, and third colors of light are different colors of light, the first LED is configured to emit light and further configured to detect light, and the second and third LEDs are configured to emit light and not detect light; and an interface coupled with the pixel module, wherein the interface receives an output signal and transmits an input signal wherein
the interface is calibrated to transmit the input signal to the pixel module, the input signal corresponds to emitting light within a first range of wavelengths by the first LED, and the first LED is configured to emit light within the first range of wavelengths,the interface is calibrated to receive the output signal from the pixel module, the output signal corresponds to light detected by the first LED within a second range of wavelengths, and the first LED is configured to detect light within the second range of wavelengths,a first wavelength within the first range of wavelengths is emitted by the first LED, anda second wavelength within the second range of wavelengths detected by the first LED are different wavelengths. |
