Abstract: An apparatus for testing a back light unit is provided to integrate a signal generator for generating a test signal with a power supply unit to test an automatic color calibration function rapidly and easily, thereby improving productivity. An apparatus for testing a back light unit includes a power supply unit(110) and a signal generator(100). The power supply unit supplies power to an LED(Light Emitting Diode) back light unit. The signal generator generates an IIC(Inter IC) signal for controlling the LED back light unit. The power supply unit includes a switching mode power supply. The signal generator includes a microcomputer(102) for generating the IIC signal and a memory(104) for storing predetermined data. The apparatus further includes a switching unit(120) for controlling the power supply unit and the signal generator. The apparatus further includes a first connector(130a) for connecting the power supply unit to the LED back light unit and a second connector(130b) for connecting the signal generator to the LED back light unit.

Abstract: An inverter controller and a liquid crystal display having the same are provided to prevent a waterfall by outputting a pulse width modulation signal synchronized with a vertical synchronous signal, thereby improving image quality. An inverter controller(800) includes a counter unit(820) and a pulse width modulation unit(840). The counter counts load signals(TP) and outputs a reference signal(REF) by being synchronized with a vertical start signal(STV). The counter unit is reset after the predetermined number of counts. The pulse width modulation unit outputs a pulse width modulation signal(PWM) with a variable duty ratio by comparing a dimming signal(DIM) with the reference signal. The pulse width modulation unit has a comparing unit to compare the digital type reference signal with the dimming signal, and a pulse width modulation signal output unit to output the analog type pulse width modulation signal.
