Display Management

The mobile handset market will continue to follow the trend to ever higher screen-to-body ratios and ultimately to all-screen, bezel-less smartphones. Technology developed by ams will enable accurate ambient light, color and proximity sensing solutions to operate behind OLED displays used in these next generation mobile handsets. 

Display Management in Computing
The mobile computing market continues to follow the smartphone industrial-design trend of maximizing screen-to-body ratios.

The new TCS3701 enables front-facing ambient light and proximity sensing measurements in smartphones – maximizing edge-to-edge display screen size – with sensor operation under OLED display.

An infrared proximity sensor in a mobile phone is used to disable the display when the phone is raised to the user’s ear for a voice call. Proximity sensors from ams operate through a very small aperture: this keeps optical cross-talk to very low levels, almost eliminating the risk of false detection events.

The small aperture optical sensing devices from ams are based on a refined analog front end and digital circuitry, and innovative package design techniques, producing the lowest possible noise floor.

The same ability to operate through a small aperture is provided by the ams ambient light sensing and RGB color sensor products, which support display management functions while enabling new mobile phone designs to benefit from a sleek look with barely visible apertures. TMD3702VC enables to maximize the ratio of display area to body size while retaining front-facing proximity, color and ambient light sensing functions.
