TIME COMPENSATION-BASED LED SYSTEM |
| 摘要 |
One example includes a light-emitting diode (LED) system. The LED system includes an LED array comprising a plurality of LEDs that are each activated to provide an LED current therethrough to provide illumination in one of a plurality of colors. The LED system also includes an LED controller configured to activate the plurality of LEDs based on a digital input comprising grayscale data corresponding to activation of the plurality of LEDs and further comprising compensation time data corresponding to an activation pulse-width of each of the plurality of LEDs based on a respective one of the plurality of colors of the respective each one of the plurality of LEDs to maintain a substantially equal activation time of the plurality of LEDs. |
