Abstract: The invention discloses a control circuit for controlling a panel. The panel includes a plurality of light-emitting elements arranged as an array. Each row of light-emitting elements among the plurality of light-emitting elements are coupled to each other via one of a plurality of scan lines. The control circuit includes a current source, an emission switch, a plurality of scan switches and a level adjustment circuit. The current source is coupled to a column of light-emitting elements among the plurality of light-emitting elements. The emission switch is coupled to the current source and the column of light-emitting elements. Each of the plurality of scan switches is coupled to one of the column of light-emitting elements via one of the plurality of scan lines. The level adjustment circuit is coupled between the plurality of scan lines and the current source.
