BACKLIGHT UNIT AND A DISPLAY DEVICE HAVING THE SAME |
| 摘要 |
A backlight unit includes a dimming signal generator configured to generate first and second pulse width modulation signals, first and second driving blocks configured to receive a driving voltage to emit a light, a controller configured to receive the first and second pulse width modulation signals and an output signal from one of the first and second driving blocks to generate a voltage control signal, and a voltage converter configured to control a level of an input voltage in response to the voltage control signal to generate the driving voltage. |
