[Prior Art] A light-emitting diode (LED) is a light source that converts electrical energy into light energy. Recently, LEDs have been used in the field of illumination due to advantages of LEDs, such as rapid processing speed, low power consumption, long durability, etc., and have been used as display elements. The LED operates by receiving a source of power supplied from a power supply unit (psu). For example, when the pSU is not functioning properly, the LED may not function properly and flicker may occur. In this flicker phenomenon, light emitted from the LED may flicker. The flicker phenomenon that occurs in the LED may be affected by the state in which the power source is supplied to the PSU of the LED. Therefore, in the manufacture of the PSU, a test for determining the state of the psu can be performed.

Flicker Ratio (〇/〇) =^xl〇〇 [Equation 2]

Flicker Ratio (dB) =101og(^^TMS) In Equations 1 and 2, ACrms represents the peak of the AC component and DC represents the DC component. The flicker ratio calculated by Equations 1 and 2 can be expressed as "%" or "dB" by 18 95456 201231987. When the flicker measured using Equation 1 or 2 is less than a predetermined threshold, the second controller 257 may determine that the first PSU 211 to the eighth PSU 218 are in a normal state. When the measured flicker is equal to or greater than the predetermined threshold, the second controller 257 may determine that the first PSU 211 to the eighth PSU 218 are in an abnormal state. The second controller 257 can measure the flicker using a single group, a single optical source, and a single photodetection module of a single PSU, and can determine the state of the corresponding PSU based on the flicker measurement result.
