1. A method of driving a display panel, the method comprising:
- sending a stream of pixels from a display engine to both a first pixel interface and a second pixel interface;
transmitting a first subset of the stream of pixels from the first pixel interface to the display panel; and
transmitting a second subset of the stream of pixels from the second pixel interface to the display panel,wherein the stream of pixels is sent from the display engine to both the first pixel interface and the second pixel interface in accordance with a pixel clock; and
transmitting the first subset and the second subset of the stream of pixels in accordance with a lane clock, the pixel clock being asynchronous to the lane clock.
