METHOD FOR DRIVING A LIGHT SOURCE, DRIVING APPARATUS FOR DRIVING THE LIGHT SOURCE AND LIQUID CRYSTAL DISPLAY APPARATUS HAVING THE DRIVING APPARATUS |
摘要 |
According to one or more embodiments, an inverter provides a light source with an input voltage. A protection circuit shuts down the inverter based on an overvoltage protection level that is detected based on the input voltage. A protection circuit control part shuts down the operation of the protection circuit during a predetermined interval. Abnormal operation of the protection circuit caused by a high voltage provided when the light source is turned on may be prevented. Therefore, a turn-on defect of the light source may be prevented.
