Abstract
An inverter includes a first PMOS transistor having a gate electrode coupled to a first input port, a first electrode coupled to a first node and a second electrode coupled to the gate electrode or a second power source; a second PMOS transistor having a gate electrode coupled to the first input port, and first and second electrodes coupled respectively to a first power source and an output port; a third PMOS transistor having a gate electrode coupled to the first node, first and second electrodes coupled respectively to the output port and a second input port; and a capacitor coupled between the first node and the output port.
Claims7
An inverter comprising:
- a first PMOS transistor having a gate electrode coupled to a first input port, a first electrode coupled to a first node, and a second electrode coupled to the gate electrode or a second power source;
- a second PMOS transistor having a gate electrode coupled to the first input port, and first and second electrodes coupled respectively to a first power source and an output port;
- a third PMOS transistor having a gate electrode coupled to the first node, first and second electrodes coupled respectively to the output port and a second input port;
- and
- a capacitor coupled between the first node and the output port.
A display device comprising a display unit, a scan driver, a data driver and a controller, wherein the scan driver comprises:
- a shift register for sequentially supplying a signal supplied to scan lines;
- a level shifter for converting the signal received from the shift register to a predetermined voltage level and supplying the converted signal;
- and
- a buffer for outputting the signal received from the level shifter to each of the scan lines, wherein the buffer comprises a plurality of inverters, each of the inverters comprising three PMOS transistors and one capacitor.
