DRIVING APPARATUS FOR A LIGHT EMITTING DEVICE AND METHOD FOR THE SAME |
| 摘要 |
A driving apparatus configured to drive a light emitting device includes a driving current source module operable to supply current to the light emitting device via a node during operation. A protection module coupled to the node and the driving current source module selectively injects current to the node during operation. The driving current source module is controlled based on a detection result of a voltage on the node. |

1. An apparatus, comprising:
a driving current source module including an operational amplifier coupled to a drive transistor that is configured to supply current to a light emitting device via a node; and a circuit included in the driving current source module that is configured to improve dimming accuracy by reducing delay caused by the operational amplifier upon dimming in a pulse width modulation (PWM) mode. |
