Abstract
A device may include a photosensitive transistor and a light-emitting diode. The light-emitting diode may include an anode. The anode may include a first portion having a first thickness and a second portion having a second thickness, wherein the second thickness is less than the first thickness. The device may also include driving circuitry that receives a data signal and causes light to emit from the light-emitting diode in response to the data signal. The photosensitive transistor may generate an electrical signal in response to light emitted from the light-emitting diode during the light emission.
