The mobile phone market tends to be saturated, which makes the products enter a fast iteration period and become a fast-moving consumer goods. All major terminal brand manufacturers are struggling to find new screaming innovations and stimulate users to pay.
In the past two years, the new darling of the dual-camera and curved-faced brand manufacturers, the former has the Xiaomi MIX comprehensive screen and the Samsung S8/S8 Plus hyperboloid full-screen, the latter has Huawei and OPPO two giant layout. In addition to the 3D Touch pressure-sensitive screen technology, the Apple iPhone 7/7 Plus adds a pressure touch function to the Home button, adding a different color to the market. However, this obviously did not meet expectations and set off a new round of national frenzy.
Perhaps the road to micro-innovation for mobile phone hardware is coming to an end. The new technology will bring a disruptive operating experience and comprehensively innovate human-computer interaction will be a new direction, just as Steve Jobs ended the era of Nokia's hegemony with a generation of iPhone.
CITE2017 The 5th China Electronic Information Expo In the same period, 2017 mobile phone 3D touch display black technology summit, the general manager of the core technology MCU business unit Xie Yibo brought the "human-computer interaction revolution - pressure touch technology" keynote speech Explained in detail.

Pressure touch, eliminate all mobile phone buttons!In Xie Yibo's view, 3D curved surface full screen + zero mechanical button will trigger a new round of adrenaline excitement for consumers, which redefines the human-computer interaction experience while improving the appearance of the mobile phone, such as sliding the side to achieve one-handed Operate, adjust the volume, lightly hold the phone to wake up, and enhance the waterproofness of the whole machine.
It is rumored that the iPhone 8 will use the full body sensing, while optimizing the Touch ID technology, the user fingerprint can be recognized by displaying the touch screen, in place of the Home button.

However, in the process of achieving this wonderful goal, how to make the interaction more reliable and stable is a problem that must be solved. Xie Yibo said that in the past 14 years, Xinhai Technology has been focusing on the research and development of pressure detection signal chips, as well as the continuous innovation of solutions and algorithms. The company's R&D staff is over 70%, and has a number of technical patents. It also has its own unique advantages in the field of pressure touch. .
The core mechanical key pressure control solution of Core Technology supports the hidden pressure sensitive Home button + side hidden pressure sensitive button. The principle is to stick the flexible pressure sensor under the back plate when the pressure sensor detects a slight deformation. (Support for detecting the minimum deformation of 1μm) will output a voltage signal, and the core touch panel of the Force Touch (the 3D Touch) SOC chip will convert it into a pressure value and upload it to the AP layer of the mobile phone through the communication interface, thus generating functional feedback. To achieve the transformation of the interactive experience.

Core Sea Technology's pressure touch solution has four advantages, one is cost-effective, high sensitivity, high linearity; the other is deep integration of sensors, 3D Touch chip architecture and algorithms to achieve ultra-low power of the system The third is the deep integration of hardware and software to achieve high reliability; the fourth is easy to assemble, just press the pressure module under the glass to perform deformation identification.
In fact, the pressure touch technology of Xinhai Technology has already been verified on smart home appliances, such as smart range hoods. With the pressure touch panel material changing from glass to stainless steel and aluminum alloy, the traditional capacitive pressure The touch can't be used, and Core's pressure touch solution solves this problem well. It can be used to identify any material such as glass and metal. It can be applied to the mobile phone. In addition to the full screen of 3D surface, it also supports straight face + The metal side touch operation makes it easier for brand manufacturers to design products more flexibly.

However, it should be noted that the possibility of misoperation of the edge pressure is very large, which requires an algorithm to solve. At present, Core Technology is conducting in-depth research on sensors, 3D Touch SOC architecture and application scenarios, and hopes to continuously optimize Algorithm to improve reliability.
The screen screen pressure touch completes the interactive supplement, and the game application will welcome the new explosion point.In addition, Core Technology will also introduce a 3D curved screen pressure touch solution. Xie Wei waveform example, the two-dimensional touch screen is equivalent to the left button of the mouse, and the screen pressure touch realizes the right-click menu function, and completes the interactive supplement.
"When Apple first introduced 3D Touch technology, there was a short-lived app for the development of the technology. In the future, pressure touch will help the game-like APP to open the third-dimensional operation - gravity sensing, which will be very interesting. The application is worth looking forward to."

Why do you like to use ferrite magnets? Because it does not rust, does not oxidize, does not corrode and is absolutely environmentally friendly.
Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
