Eliminating Infrared Hardware on Smartphones to Improve Performance and Robustness
By MedTech Outlook | Friday, March 15, 2019
Sensors are crucial for the growth of mobile device functionality, where a proximity sensor was one of a smartphone’s most important part. It helps to detect proximities by automatically switching off the touchscreen when the sensor enters a predefined range of an object using the device. The optical proximity sensor requires one rectangular black shape or two large holes on the screen; these sensors detect when users are in a call mode in order to deactivate the touchscreen.
Smartphone designers wanted to remove these unattractive holes on the phone's faceplate for a long time, but a user’s cheek could accidentally trigger functions on the screen without the proximity sensor functionality.
Elliptic Labs is a global enterprise that creates smart virtual sensors. Virtual sensors and gesture sensing technology from Elliptic Labs continues to transform with the consumer electronics market. Elliptic Labs has a worldwide presence in the USA, Europe, and Asia.
Recently, Elliptic Labs partnered with Solomon Systech Limited to enable the smartphone market to take a major step toward the elimination of the obsolete IR proximity sensor. The removal of the IR sensor gives an almost complete display for smartphones, which OEMs now see as a must.
Solomon Systech Limited is a global market leader in mobile display ICs and manufactures of a wide range of driver ICs that support all major display technologies such as LCD and OLED. The group also offers ICs in new display markets, including bistable electronic paper display drivers and microdisplay controllers.
OEMs use Elliptical Labs' AI Virtual Smart Sensors Platform software to enhance their device capabilities, especially in the smartphone and IoT markets. All the products of the company’s platform use ultrasound to offer different capabilities.

The partnership between Elliptic Labs and Solomon Systech Limited enables a software-based proximity sensor solution that eliminates the IR hardware and replaces it with more robust, efficient software that opens up more screen property.
Now, touch sensor data from the AMOLED Touch Controller IC family of Solomon Systech that combines capacitive touch screens with Elliptic’s INNER BEAUTY virtual proximity sensor data to provide a data fusion that makes the solution more accurate than ever before. This can work with any smartphone.
