    • A mobile computing device an emissive display that includes a touchscreen and a proximity sensor. The proximity sensor includes a transmitter configured to transmit electromagnetic radiation through the display and a receiver of electromagnetic radiation configured to receive electromagnetic radiation transmitted by the transmitter, reflected off an object facing the emissive display and received through the emissive display. The proximity sensor is configured for generating a quantitative output signal based on an amount of the received electromagnetic radiation, and the transmitter is configured to transmit a first predetermined amount of light when a distance between the object and the display is greater than a near threshold distance between the object and the display and is configured to transmit a second predetermined amount of light when the distance between the object and the display is less than the near threshold distance. The second predetermined amount is greater than the first predetermined amount. A processor is configured for receiving the generated quantitative output signal, and memory stores instructions that, when executed by the processor, cause the processor to deactivate the touchscreen and/or the emissive display when the touchscreen and/or the emissive display is activated and when the quantitative output signal increases above an high threshold value and to activate the touchscreen and/or the emissive display when the touchscreen and/or the emissive display is deactivated and when the quantitative output signal is below a low threshold value, the low threshold value being less than the high threshold value.
