A display includes a display panel, a pixel driving unit and a power supply for supplying power to the pixel driving unit. The display panel includes a plurality of pixels arranged in a matrix manner. The pixel driving unit is used for driving the pixels. The power supply includes an input power source, an output capacitor for providing an output voltage, and a control unit for controlling the input power source, such that in a frame period, the input power source charges the output capacitor during the non-refreshing duration of the pixels by the input power source and stops charging the output capacitor during the refreshing duration of the pixels.

Display and power supply control method of a display

A light source system and a method for driving light emitting diodes (LEDs) are provided. The provided light source system includes: an LED module having a plurality of LED strings operated under a direct current (DC) output voltage; and a driving unit coupled to the LED module, and used for providing the DC output voltage by adopting a boost means and generating a plurality of pulsation current signals according to a setting signal so as to respectively drive the LED strings, in which the frequencies of the pulsation current signals are higher than a predetermined frequency.
