A light source for a display device includes a board and light emitting diodes mounted on the board. The light emitting diodes include a white light emitting diode which emits white light and a red light emitting diode which emits red light.
A light emitting device includes a time delay mechanism in electrical connection with a power source for time shifting at least a portion of a power signal outputted by the power source and a plurality of light emitting units formed by at least a light emitting diode (LED)structure, each light emitting unit being driven alternately and sequentially using the power source and the time delay mechanism.
