20100052572 | LIGHT EMITTING ELEMENT DRIVING APPARATUS - The N light emitting element groups each include one or more light emitting elements. The power source circuit includes a control input terminal and supplies the power source voltage to the N light emitting element groups. The N current driving circuits, each including a feedback output terminal, generate N drive currents for driving the respective N light emitting element groups and generate main feedback voltages at the feedback output terminals based on the power source voltage. The main feedback circuit applies a main feedback signal to the control input terminal based on the N main feedback voltages. The auxiliary feedback circuit applies an auxiliary feedback signal to the control input terminal based on the power source voltage. The power source circuit adjusts the power source voltage based on at least one of the main feedback signal and the auxiliary feedback signal. | 03-04-2010 |

20110291634 | OVERCURRENT PROTECTION CIRCUIT AND OVERCURRENT PROTECTION METHOD - An overcurrent protection circuit includes: a determiner configured to determine whether or not the switch current exceeds a predetermined threshold, that is, the switch current is an overcurrent state when the switching element is turned ON; an OFF period setting counter configured to increase or decrease a counter output depending on a determination result of the determiner; and a drive signal generator configured to generate a drive signal of the switching element such that a length of an ON timing interval of the switching element corresponds to the counter output of the OFF period setting counter. | 12-01-2011 |
20120074856 | LIGHT-EMITTING ELEMENT DRIVING DEVICE - Short circuit failures and open circuit failures of light-emitting elements used for the backlight in an LCD panel can be reliably and easily detected. The voltage at the node between each series-connected light-emitting element array and a drive circuit is detected as a monitored voltage. A maximum detector detects the highest and a minimum detector detects the lowest of these monitored voltages. Short circuit or open circuit failure of a light-emitting element is detected by comparing the voltage difference between the maximum detector output and the minimum detector output with a specific reference voltage. | 03-29-2012 |
