Patent ID: 7786788

Claim:
A system for displaying images, comprising: a level shifter operative to transform an input signal having first low and high potential levels into an output signal having second low and high potential levels, the level shifter comprising: a voltage distributor operative to receive the input signal and distribute potential levels at a first node and a second node to respectively output a first signal and a second signal according to the input signal, and the voltage distributor comprising: a first transistor having a first electrode, a second electrode, and a first control electrode, wherein the second electrode is coupled to the first node, and the first control electrode receives the input signal; a switch, electrically connected between the first node and the second node, operative to selectively establish an electrical connection between the first node and the second node; and a second transistor having a third electrode, a fourth electrode, and a second control electrode, wherein the third electrode is coupled to the second node, and the second control electrode is directly connected to the first node; and an output circuit, electrically connected to the voltage distributor, operative to generate the output signal according to the first signal and the second signal provided by the voltage distributor.
