| 20100327758 | LED Light Emitting Device And Driving Method Thereof - The present invention relates to an LED light emitting device and a driving method, and discloses a technology that may improve a slew rate of a channel current flowing through an LED channel when driving with a pulse width modulation method. For this, the present invention includes an LED channel consisting of a plurality of LED elements that are consecutively and serially connected, a current control switch that is connected to the end of the LED channel and performs a switching operation, and an operational amplifier that controls the switching operation of the current control switch according to a pulse width modulation signal. The LED driver samples an output voltage at the operational amplifier when the pulse width modulation signal is in an on state, and maintains the output voltage of the operational amplifier when the pulse width modulation signal is in an off state. | 12-30-2010 |
