BACKLIGHT UNIT |
| 摘要 |
A backlight unit capable of substantially reducing a change in a level of a driving current includes: a light source; a static current switching element connected between the light source and a sensing node and controlling a driving current supplied to the light source; a sensing resistor connected between the sensing node and a ground; a static current controller controlling an operation of the static current switching element based on a sensing voltage from the sensing node and an externally supplied driving current control signal; and a driving current corrector generating the driving current control signal and correcting a level of the driving current control signal based on the sensing voltage. |
