Edp mipi dsi combination architecture

A method of selecting amongst multiple display interfaces, comprising:

• selecting a display interface from two or more display interfaces, the selected display interface having a lower power than unselected display interfaces of the two or more display interfaces;
• disabling transistors of a high speed portion of a display interface driver in response to the selecting, the disabling including providing bias voltages to gates of the transistors of the high speed portion to prevent gate dielectric breakdown of the transistors while a low power portion of the display interface driver is driving data signals of the selected display interface;
• and
• driving data signals of the selected display interface through an output, wherein voltages of the data signals also reach the transistors.

A computing system comprising:

• a graphics controller;
• and
• a display controller coupled to the graphics controller, the display controller having a driver, the display controller being configurable to select amongst two or more display interfaces, the driver designed to drive respective signals for each of the two or more display interfaces through a single output;
• the driver comprising a high speed pull-up/pull-down driver and a low power pull-up/pull-down driver whose respective outputs are coupled to the output;
• and
• wherein the high speed pull-up/pull-down driver includes transistors whose gate dielectrics are thinner than transistors of the low power pull-up/pull-down driver.
