Patent ID: 8345033

Claim:
An image processing apparatus comprising: a display unit which displays thereon an input image; and a power supply unit which outputs direct current power to drive the display unit, and gradually increases a voltage level of the direct current power, wherein the power supply unit gradually increases the voltage level of the direct current power to apply initial power to the display unit, wherein the power supply unit comprises a delay unit which gradually delays the increase in the voltage level of the direct current power for at least one time period, wherein the delay unit comprises a comparator which senses the voltage level of the direct current power and compares the voltage level of the direct current power with a reference voltage, and gradually delays the increase in the voltage level of the direct current power for at least one time period based on an output signal of the comparator, and wherein the delay unit comprises a plurality of delay circuits which gradually delay the increase in the voltage level of the direct current power for at least one time period based on the output signal of the comparator, and wherein each delay circuit of the plurality of delay circuits are coupled to each other in parallel.
