Austria microelectronics corporation (ams AG) new close sensor and close/ambient light sensor module, the module can assist the Android smart phone manufacturers will phone display screen glass under the sensor aperture shrinks to minimum diameter.

TMD2620 in eliminate optical crosstalk effects at the same time, close to the sensor and TMD2725 ambient light sensor module will be LED in the transmitter to the distance sensor to 1 mm. TMD2620 in eliminate optical crosstalk effects at the same time, close to the sensor and TMD2725 ambient light sensor module will be LED in the transmitter to the distance sensor to 1 mm. Using TMD2620 sensors or combined with close and close to the ambient light perception function TMD2725 sensor, can make the smartphone manufacturers to reduce as much as 50%, the aperture size helps to beautify the mobile phone appearance, especially white or light color border of the cell phone. TMD2620 and TMD2725 can make the aperture size reduced to 1.4 and 1.4 mm respectively.

TMD2620 and TMD2725 in optical module encapsulation breakthrough performance, can make between infrared emitter and photoelectric diode there is only 1 mm intervals. Emitter and sensor at the top of the lens and the light barrier between them, can be caused by reflection on surface of the display screen glass optical crosstalk to a minimum. Adjust error recorder eliminates the module close to calculate cause optical crosstalk, the influence of ambient light automatically cut further enhances the equipment is close to the accuracy of measurement. Measuring capacity up to 100 mm, and even can be comparable with the laser solutions.

Austria microelectronics sensor market manager Herbert Truppe, said: "so far, unable to overcome the optical crosstalk problems, Android phone makers can't to be close to induction hole reduced to 3 mm. Now TMD2620 TMD2725 and overcome the challenges, making it possible to select a smaller aperture."

TMD2620 and TMD2725 is in mass production.
