Light-source module for display device and display device having the same

Abstract

A light-source module for a display device and a display device having the same, in which the light-source module includes a plurality of light-emitting units, a current difference controller, and a converter. The light-emitting units are connected in parallel between a driving power input terminal and a ground terminal to emit light by the diving power and to output respective feedback control signals. The current difference controller is configured to output a plurality of power control signals according to the respective feedback control signals. The converter is configured to change a current of the driving power provided to the light-emitting units according to the power control signals. The amounts of currents flowing through the light emitting units each having a plurality of light emitting diodes are measured and the levels of voltages applied to the light-emitting units are changed according to the measurement results. Accordingly, a current difference between the light emitting units can be reduced and the brightness uniformity of the light source can be improved.
