Zusammenfassung:A novel level-shifter circuit for display panel driver is presented. A proposed level-shifter is for the high speed and high-voltage driving capability. In order to achieve this purpose, the proposed level-shifter restricts and separates the V gs of the output driver's pull-up PMOS and pull-down NMOS with Zener diode. The Zener diode can be replaced by normal diode combination. And a speed-up PMOS transistor is introduced to reduce delay. The control signal of speed-up PMOS was designed by bootstrapping method to minimize the gate to source (V gs ) voltage to avoid V gs breakdown.
