Request InfoOsram Opto Semiconductors Inc.SUNNYVALE, Calif., April 29, 2013 — Osram Opto Semiconductors’ new compact SFH 7776 digital sensor registers the ambient brightness in smartphones and prevents unintentional responses from the touch screen during calls, enabling smartphone designers to control the backlighting and touch functions of displays. The sensor uses an IR LED and two detectors to register the ambient brightness to control the display backlighting so that it can be easily read while consuming as little power as possible. It emits IR light that is reflected by approaching objects — such as your ear — to deactivate the touch...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra November 2023 IssueMiniature IR Sensor ModulesThe dual-lens TSMP95000 and single-lens TSMP96000 and TSMP98000 from Vishay Intertechnology are miniaturized infrared (IR) sensor modules for remote control systems that combine a wide supply voltage...Photonics.com 3/28/2024Smartphone Image SensorThe OV50K40 from OMNIVISION is a smartphone image sensor with the company’s TheiaCel™ high dynamic range technology with single exposure.
