Light-Emitting Device With Chromatic Control |
摘要 |
The light-emitting device includes a base substrate and preferably three light-emitting diodes respectively associated with three primary colors and emitting a part of their signal in the direction of the base substrate. The device includes three chromatic photodetectors formed in the base substrate constituting a semiconducting substrate, and each arranged under an associated light-emitting diode. Each chromatic photodetector includes superposed first, second and third layers. The first layer and third layer have a first type of conductivity and the second layer has a second type of conductivity. The device includes a control component connected to the chromatic photodetectors and to the light-emitting diodes to control the global color of the light emitted by the device.
