AMS announces 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.
By developing this ‘Behind OLED’ ambient light/proximity sensor, AMS enables smartphone manufacturers to achieve the highest possible ratio of display area to body size while retaining crucial touchscreen disablement and automatic display brightness/color adjustment functions, which require an RGB/infrared light sensor.
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.
Ultra-high sensitivity to light means that it can still produce accurate light measurements in all lighting conditions.
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.
Unit pricing is $1.25 in an order quantity of 1,000 units.
