摘要 |
A light-responsive light-emitting diode display comprises a light-emitting diode circuit including a series connection of light-emitting diodes and a light-responsive current-controlling circuit connected in series to said light-emitting diode circuit for supplying a current thereto in correspondence with the ambient brightness. A unipolar photo-transistor can provide a current above a predetermined minimum value and increasing with the intensity of incident lights and can absorb excess voltages when applied. Light-responsive current-control reduces the useless power dissipation, and all solid-state display provides a very long service life. |
