摘要

PURPOSE: A driving device of a light emitting element is provided to improve the efficiency of a system without additional costs as groups of light emitting elements are connected to each other in series or rows. CONSTITUTION: A switching unit comprises a first switching unit(211) and a second switching unit(213). The first switching unit comprises a plurality of switching elements. The second switching unit comprises the plurality of switching elements. The first switching unit is placed between a power source(Vdd) of a power unit and one side of a light emitting unit(240). The first switching unit operates sub light emitting units, respectively. [Reference numerals] (220) Base voltage connecting unit
