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 the 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 the first node and a second voltage at the second node; wherein a difference between a first positive voltage of the first positive voltage source and the first voltage is smaller than a first threshold and a difference between a first negative voltage of the first negative voltage source and the second voltage is smaller than a second threshold.
