DRIVING CIRCUIT FOR LIGHT EMITTING ELEMENT |
| 摘要 |
A driving circuit for causing a light emitting element to emit light in response to a driving signal is provided. The driving circuit comprising a first current supply circuit that starts to supply a driving current to the light emitting element in response to the driving signal, a second current supply circuit that starts to supply a supplementary current to the light emitting element in response to the driving signal. The second current supply circuit stops to supply the supplementary current upon detecting that a voltage applied to the light emitting element has reached a threshold voltage. |

1. A driving circuit for causing a light emitting element to emit light in response to a driving signal, the driving circuit comprising:
a first current supply circuit that starts to supply a driving current to the light emitting element in response to the driving signal; a second current supply circuit that starts to supply a supplementary current to the light emitting element in response to the driving signal; wherein the second current supply circuit stops to supply the supplementary current upon detecting that a voltage applied to the light emitting element has reached a threshold voltage. |
