Abstract: A backlight unit includes; a light source, an inverter which provides the light source with an input voltage, and a printed circuit board (“PCB”) connected to the light source, wherein the PCB includes a protection circuit which detects an open-lamp-protection voltage which varies according to a change of the input voltage and changes a reference voltage according to the change of the input voltage, wherein the protection circuit turns off the inverter when the detected open-lamp-protection voltage is higher than the changed reference voltage.
Abstract translation: 背光单元包括： 光源，向光源提供输入电压的逆变器，以及连接到光源的印刷电路板（“PCB”），其中PCB包括检测开关灯保护电压的保护电路，该保护电路变化 根据输入电压的变化，根据输入电压的变化来改变参考电压，其中当检测到的开路灯保护电压高于改变的参考电压时，保护电路关闭逆变器。
