Ambient Light and Proximity Sensor
ams OSRAMRequest Info
The TMD2712 ambient light and proximity sensor module from ams AG features a miniature 1 × 2-mm footprint.
The module fits in the same teardrop notch of an LCD touchscreen display as a selfie camera, supporting the trend for phone designs with a minimal bezel or even no bezel. The design maximizes the screen-to-body ratio and gives the user the greatest possible viewable display area. The sensor is a complete system solution for accurate ambient light sensing, enabling display brightness management to maintain comfortable viewing in all lighting conditions. It incorporates a low-power infrared vertical cavity surface emitting laser (VCSEL) emitter and VCSEL driver, IR and visible light photodiodes, and control logic.
The module’s VCSEL emitter and photodiodes are offset from the package center line to give the manufacturer greater flexibility in the placement of the sensor alongside other components such as the camera. The module’s proximity detection engine, which offers improved rejection of optical crosstalk, operates reliably over a long range with a wide field-of-view, avoiding the need for dedicated components such as a light pipe, interposer, or special ink.
