Proximity Sensor with Separate Near-Field and Far-Field Measurement Capability
First Claim
1. An electronic device, comprising:
- a proximity sensor that provides near-field measurement results and far-field measurement results;
processing circuitry that receives the near-field measurement results and the far-field measurement results from the proximity sensor; and
a display, wherein the processing circuitry selectively enables and disables the display based on the received near-field measurement results and the far-field measurement results.

Abstract
An electronic device that includes a proximity sensor may be provided. The proximity sensor may be a time-of-flight-based proximity sensor that is capable of separately outputting near-field measurements and far-field measurements. The near-field and far-field measurements may be placed in separate bins according to their time-of-flight values. The discrimination between near-field and far-field results may allow the electronic device to filter out false positive events where the presence of smudge or other surface contaminants can otherwise produce skewed readings and also to filter out false negative events where the presence of a user with dark hair or skin can otherwise produce misleading sensor results.
