A display panel with reduced power consumption is described. An example of the display panel includes an array of light emitting elements that are controllable to form an image, and a Thin-Film-Transistor (TFT) backplane comprising circuitry to drive the array of light emitting elements. The TFT backplane includes a plurality of field effect transistors (FETs). Each FET includes a source electrode, a drain electrode, a channel layer contacting the source electrode and the drain electrode, and a gate electrode adjacent to the channel layer and separated from the channel layer by an insulator. The channel layer includes a layer of metal phosphide.
