ams (SIX: AMS), a leading worldwide supplier of high performance sensor solutions, today announced the release of the TCS3701, an RGB light and IR proximity sensor IC which can accurately measure the intensity of ambient light from behind an OLED screen. This capability supports today’s industrial design trend to maximize smartphone display area by eliminating front-facing bezels, where an ambient light/proximity sensor is typically located.
By developing this ‘Behind OLED’ ambient light/proximity sensor,
Despite the constraint of operating behind an emissive OLED display screen, the TCS3701 senses the addition of the ambient light passing through the display to light emitted by the display’s pixels located just above the sensor.
The TCS3701’s 2.0mm x 2.5mm x 0.5mm OQFN package is small enough to be placed behind a smartphone’s OLED screen. It gives a smartphone designer the flexibility to mount an IR emitter to support the proximity sensing function in the best front-facing location. Cross-talk compensation algorithms provide for reliable proximity sensing performance.
“Smartphone OEMs today are striving to maximize their products’ screen-to-body ratio, reducing the bezel area as much as possible on the display’s face,” said David Moon, Senior Marketing Manager at
The TCS3701 is available for sampling now. Unit pricing is $1.25 in an order quantity of 1,000 units. For more technical information and to request samples or an evaluation board, go to www.ams.com/TCS3701.
