New fingerprint recognition technology in the development of smart phones or pick up the Home key revolution

8:00 electronic enthusiasts News: According to foreign media reports, the smart phone's Home button function, the fingerprint back to the main screen, various manufacturers are stepping up the pace of development of parts instead of the Home key to execute the same instruction, shortly after the Home key will likely Disappeared from the phone.

According to ET News, recent industry news indicates that SynapTIcs has successfully developed the fingerprint sensor FS9100, which does not require a button. The sensor can penetrate 1mm of protective glass to identify the fingerprint of a smartphone or tablet user.

Since the development of fingerprint recognition technology, the finger still needs to directly touch the sensor to accurately recognize it, so the smart phone or tablet computer retains the raised circular or square button design.

Sensors developed by SynapTIcs do not require such buttons. The optical technology developed by them allows fingerprints to penetrate the protective glass, so fingerprints can be fingerprinted without the need for a direct touch sensor.

According to SynapTIcs, the sensor is placed underneath the 2.5D protective glass inner layer. It is not necessary to make room for the buttons, and the glass does not need to be thinned.

Since the development of fingerprint recognition technology, it is necessary to use the Home button to sense fingerprints to enter the main screen of a smartphone or tablet, so the Home button has always been a must-have design.

However, the existence of the button not only hinders the design, but as the smartphone begins to emphasize the waterproof and dustproof functions, various technologies are applied to replace the physical buttons that are not easily waterproof or dustproof.

Qualcomm developed the ultrasonic fingerprint recognition technology to replace the Home button, called Snapdragon Sense ID 3D. This technology uses ultrasonic waves to pass through various materials such as glass, aluminum and stainless steel for fingerprint recognition and recognition in 3D. Fingerprint texture, curves and pores, Xiaomi's flagship product, the 5S smart phone, is the first to carry this technology.

South Korea is also developing a home key alternative. CrucialTec and LG Innotek have developed a technology to set up Home keys and sensors on the back of the protective glass, which is currently being commercialized.

When these technologies are commercialized, smartphones with the Home button disappearing will be expected to accelerate. Although SynapTIcs has not released specific supply targets, it is expected to provide samples starting in early 2017 and is scheduled to begin mass production in the second half of 2017. Synaptics and Swedish FingerPrint Cards (FPC) will join forces to capture the global smartphone fingerprint sensor market. .

On the other hand, the industry speculates that Samsung Electronics and Apple's next-generation products may also adopt a homeless design.

Game Machine Wiring Harness

The wire harness simplifies the building of these larger components by integrating the wiring into a single unit, or several units, for [drop-in" installation. By binding the many wires, cables, and subassemblies into a harness, the OEM or installer only has one component to install. In addition, a wire harness allows the completed assembly to be better secured against the effects of abrasion and vibration, and by constricting the wires into a non-flexing bundle, usage of space is optimized.
