China, October 22, 2020-Ams semiconductor (ams AG, Swiss stock exchange stock code: AMS), the world’s leading supplier of high-performance sensor solutions, announced that it has adopted a very small package of 1 mm x 2 mm The integrated ambient light sensor (ALS) and proximity light sensor module TMD2712 make the smart phone light sensor miniaturization to a higher level.
The thickness of the TMD2712 is only 0.5 mm, and it can be placed in the teardrop-shaped notch of the LCD touch-screen Display together with the selfie camera. This can support the realization of the smallest or no border mobile phone design trend-this ID design method can maximize the screen-to-body ratio and provide users with the largest visible screen display area.
This new sensor is a complete system solution for accurately detecting ambient light, supporting display brightness management—to ensure a comfortable visual experience under all lighting conditions, and providing reliable proximity detection—very close to objects on the front of the phone (Such as the user’s face) when the touch screen display is turned off. It integrates a low-power VCSEL transmitter, infrared and visible light photodetectors, and related control logic.
Relying on professional sensor technology, deep understanding of ALS and proximity detection applications, and quality assurance under mass production conditions, ams will bring great challenges to smart phone manufacturers in the development of next-generation mobile phones when facing severe challenges. Great confidence.
Jian Liu, strategic project director of integrated optical sensors at ams, said: “The TMD2712, an advanced integrated ambient light and proximity light sensor for mobile phones with LCD screens, has further enriched customers’ choices of optical sensors for smartphones. From the assembly of LCD For mobile phones with screens to OLED screens, ams provides advanced products and technologies to promote the realization of bezel-less designs for mobile phones. From the current industry’s first under-screen ambient light sensing, proximity light detection and light source flicker detection sensor module TMD3719, to refresh The smallest recorded ambient light and proximity light sensor module TMD2755-intended to support a narrow slit design with a large air gap, to the latest and renewed appearance size record TMD2712-optimized design for small air gaps, used in front of Put the cameras together in the drop-shaped notch on the LCD display screen.”
Easy to integrate into the display design of a smartphone
TMD2712 is easy to integrate into the display assembly and can accurately measure IR and ambient light. The module’s VCSEL transmitter and photodiode have been specially designed to be eccentric, allowing manufacturers to more flexibly combine and place sensors and other components, such as cameras. The module’s proximity light detection engine provides better light crosstalk suppression, can operate reliably over long distances, and provides a wide viewing angle without the use of light pipes, raised boards or special inks.
By using a VCSEL transmitter and implementing power optimization in the module, TMD2712 can reduce power consumption and minimize the consumption of battery power by the sensor. The TMD2712 sensor circuit uses a 1.8V power supply and consumes only 0.7µA in sleep mode.
Samples of the TMD2712 ALS and proximity light sensor are now available. Ams can provide evaluation boards according to customer requirements.
