1. A display comprising:
a display substrate having an active display area comprising a plurality of first display subpixels, and
a transceiver circuit arranged to drive the display in a first mode of operation or in a second mode of operation;
wherein:
the first display subpixels comprise micro light-emitting diodes and/or resonant-cavity light emitting devices,
in the first mode of operation, the transceiver circuit provides a forward bias to the first display subpixels, such that the first display subpixels are operable to emit light,
in the second mode of operation, the transceiver circuit provides a reverse bias to the first display subpixels, such that the first display subpixels are operable to detect light, and
the first display subpixels comprise:
a red display subpixel that emits in a red band and detects in a green band and a blue band;
a blue display subpixel that emits in the blue band and detects in the red band and the green band; and
a green display subpixel that emits in the green band and detects in the red band and the blue band.
