Smaller Light Sensors, Better Performance

With its TMD2620 proximity sensor and TMD2725 ambient light sensor (ALS) modules, ams AG reduces the LED emitter-to-sensor gap to just 1.0 mm while eliminating the effect of optical cross talk. The TMD2620 and TMD2725 enable aperture size as small as 1.4 and 2.0mm respectively. This means that android smartphone manufacturers can reduce the sensor aperture in the display’s cover glass to its smallest diameter. In addition to the reducing the optical module’s packaging, the design of lenses on top of the emitter and sensor along with an optical barrier between them helps to minimize crosstalk, caused by reflections from the surfaces of the cover glass. Offset adjustment registers eliminate the effect of any residual crosstalk from the module’s proximity calculations.
