Abstract
A driving module for a display device includes a first transistor, comprising a gate coupled to a first node, a drain coupled to an output end, and a source coupled to a first positive voltage source; a second transistor, comprising a gate coupled to a second node, a drain coupled to output end, and a source coupled to a first negative voltage source; and a voltage generating unit, coupled to an input end, a second positive voltage source and a second negative voltage source for generating a first voltage at first node and a second voltage at second node according to a control signal from input end; wherein voltage difference between a first positive voltage of first positive voltage source and first voltage is smaller than first threshold and voltage difference between a first negative voltage of first negative voltage source and second voltage is smaller than second threshold.
