Abstract: A display driver includes an input node for receiving display data, a level shift circuit configured to convert voltage level of the display data and output a first voltage and a second voltage based on the display data, an output node for outputting the output display data, a first P-channel MOS transistor coupled to the output node, whose gate is configured to input the first voltage, and a first N-channel MOS transistor coupled to the output node, whose gate is configured to input the second voltage, wherein a voltage difference between the second voltage and the first voltage varies based on the display data.

Abstract: In a level shift circuit, input signals are input into gates of a first and a second MOS transistors whose sources are coupled to a first supply voltage VSS. Gates of a third and a fourth MOS transistors whose sources are coupled to a second supply voltage are coupled to drains of the second and the first MOS transistors. A first voltage generation circuit is coupled between the drains of the first and the third MOS transistors, and a second voltage generation circuit is coupled between the drains of the second and the fourth MOS transistors. The gate of the fifth MOS transistor is coupled to a connection node NDB, and the source of the fifth MOS transistor is coupled to the second supply voltage.
