ams introduces industry's smallest ambient light and proximity light sensor module to maximize smartphone screen-to-body ratio

     ams, a leading global provider of high-performance sensor solutions, announced that it has miniaturized smartphone light sensors by up to higher level.the TMD2712 is only 0.5 mm thick and can be placed in a teardrop-shaped notch along with the selfie camera on the LCD touchscreen display. This can support the trend of mobile phone design with minimal bezels or no bezels---this ID design method can maximize the screen ratio and provide users with the largest visual screen display area.

     The new sensor is a complete system solution for accurate ambient light detection, supports display brightness management - to ensure a comfortable viewing experience in all lighting conditions, and provides reliable proximity detection - in mobile phones Turn off the touchscreen display when the front is very close to an object, such as the user's face. It integrates a low-power VCSEL emitter, infrared and visible light photodetectors, and associated control logic.

     With expert sensor technology, in-depth understanding of ALS, proximity detection applications, and quality assurance under mass production conditions, ams offers smartphone makers the ultimate opportunity to develop next-generation handsets in the face of tough challenges. great confidence.

     Jian Liu, Strategic Program Director for Integrated Optical Sensors at ams, said: “The TMD2712, an advanced integrated ambient light and proximity light sensor for LCD-enabled mobile phones, further enriches customers’ choice of optical sensors for smartphones. From screen to OLED screen mobile phone, ams provides advanced products and technologies to promote the realization of mobile phone frameless design. From the current industry's first under-screen ambient light sensing, proximity light detection and light source flicker detection sensor module TMD3719, to refresh Smallest size record ambient light and proximity light sensor modules TMD2755 - designed to support narrow slit designs with large air gaps, all the way to TMD2712, the newest and yet another form factor record - optimized for small air gaps for use with front and rear The built-in camera is placed in the teardrop-shaped notch of the LCD display screen.”

     Easy to integrate into display assembly, the TMD2712 can accurately measure IR and ambient light. The module's VCSEL emitters and photodiodes are intentionally off-center, giving manufacturers more flexibility in the placement of sensors and other components, such as cameras. The module's proximity light detection engine provides better suppression of optical crosstalk, reliable operation over long distances, and wide viewing angles without the need for light pipes, risers, or special inks. By using a VCSEL transmitter and implementing power optimization in the module, the TMD2712 can reduce power consumption and minimize the sensor's consumption of battery power. The TMD2712 sensor circuit operates from a 1.8V supply and consumes only 0.7µA in sleep mode.
