A plurality of unit light emitting diode columns receive a voltage applied from the DC/DC converter. A plurality of transistors, respectively, are connected to the plurality of unit light emitting diode columns. A current deviation compensating unit compensates for deviations between currents respectively flowing through the plurality of unit light emitting diode columns by a pulse current width modulation average current control method. A connection switch sequentially connects the current deviation compensating unit with the plurality of transistors. A resistor is connected to output terminals of the plurality of transistors. A switch controller controls connection between the connection switch and the current deviation compensating unit based on a signal applied to the resistor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light unit and display device including the same","description":"A light unit includes a DC/DC converter.
