发明名称 DRIVING CIRCUIT OF SURFACE LIGHT SOURCE AND METHOD OF DRIVING THE SAME
摘要 A driving circuit of a surface light source and a method of driving the same are disclosed, which is suitable for decreasing the luminance-stabilization period of time and improving the low-temperature starting properties by optimizing a starting voltage and current, the driving circuit comprising an inverter controller which feedbacks a current supplied to the surface light source, and compares the feedback current to a preset reference value, to control the current supplied to the surface light source; a temperature sensor which senses an operation temperature of the surface light source; and a driving-condition determining controller which determines operation modes of the surface light source on the basis of the temperature sensed in the temperature sensor, and varies the feedback current inputted to the inverter controller according to the operation modes of the surface light source.
