POWER STABILIZING CIRCUIT AND DISPLAY DEVICE USING THE SAME

摘要

The present invention relates to a power stabilizing circuit and a display device using the same. The power stabilizing circuit includes a first switch element which is connected between an inductor and a base voltage source, a second switch element which is connected between the inductor and the output terminal of a boost convertor, and a stabilizing circuit which compares the input voltage of the boost convertor and a predetermined threshold voltage, lowers the input current level of the boost convertor or the maximum switch on time of the switch elements when the input voltage is lower than the threshold. So, the supply voltage of a display panel driving circuit can be stabilized.
