发明名称 DC-DC converter, liquid crystal display device, aging test apparatus of liquid crystal display device, and method thereof
摘要 A gate-on voltage/LED driving voltage generator includes an inductor boosting an input voltage through a PWM voltage and the input voltage, a diode and capacitor rectifying the boosted voltage, a first output terminal outputting the rectified voltage to supply an LED driving voltage to an LED, and a second output terminal supplying the rectified voltage to a gate driving circuit. Further, an aging test apparatus of an LCD device, which includes a high LED driving voltage generator in an HVS power board, and an HVI power board, may selectively perform an aging test according to a backlight unit of the LCD. Further, a DC-DC converter having the gate-on voltage/LED driving voltage generator, and the LCD including the DC-DC converter are provided.
