Intelligent machines into the touch-screen era, iPhone Apple Corp has important guiding irreplaceable role in the development of intelligent machines. The rise of multi touch screen technology and the development of Apple iPhone is closely related to.

IPhone was widely concerned by people, not only because of its simple, fashionable and fancy interface, control methods, and these are due to the multi touch screen technology. Multi touch technology is also in a few years of rapid development, and in the application of intelligent mobile phone with the rapid popularity, multi touch the technology is absolutely one of the user experience; also because of its use, we are lucky to see so many diverse ways of interface control.

Resistance and capacitance screen:

Multi touch technology makes the touch screen mobile phone rapid replacement of the dominant entity key mobile phone, mobile phone keys will abruptly squeeze under the table, this is not only because people have a new understanding of mobile phone and mobile phone control, while the development of screen technology are inseparable.

Prior to the understanding of multi touch technology, we must first know that the phone screen is divided into two kinds, one is the resistance screen, one is a capacitive screen

Resistance screen:

In simple terms, by applying pressure to the screen, producing the current and then making the screen to identify and react, this screen is characterized by the use of any object regardless of the ear to press the screen, the screen will respond

Capacitance screen:

Depending on the electrostatic induction capacitance screen to operate, is simply not to press the screen, the screen by electrostatic induction finger to generate current signal response. Capacitance screen is currently the most widely used mainstream screen. In the structure, capacitive screen on the display panel is folded into a transparent conductive metal special the material, when the fingers in the metal layer, contacts the capacitance will change, because the body electric field, users and the touch screen surface of a small magnetic field generated by current sensor of contact signal were analyzed.

The characteristics of capacitive screen, making it without relying on the pressure to achieve the related operation, so the response speed is better than resistance screen, high sensitivity, easy operation and timely communication and feedback of users. To realize the pressure resistance screen operation, the response speed is slightly slower, and the sensitivity is poor, the operation is also as the capacitive screen freely.

Although the high precision resistance screen, but are not sensitive enough, and the resistance of multi touch screen support is very limited, so the operation is relatively simple, is now basically fade smartphone platform. On the contrary, the capacitive screen is more suitable for use in multi touch technology, and durability are far higher than "resistive screen soft".

So what are the multi touch screen technology?

The concept of multi touch:

The early touch screen appears not to use multi touch screen technology, the screen can only determine a touch point, that is to say we can only use one finger to operate. If the screen at the same time there are more than two point touch, can not make the correct response.

For example, we often use the life of the ATM automatic teller machine, the use of the screen can only identify a single point of control

But the integration of multi touch screen technology, screen response to task will be broken down into two aspects, one is the signal collected at the same time multi touch the two is for each signal significance to judge and make a correct analysis and response, so as to realize the five finger recognition screen at the same time do click the touch action.

Structure and core technology:

We now use the mainstream mobile phone screen supports multi touch, it is straightforward to say the principle of adding a layer of transparent touch panel at the top of the LCD panel, the touch panel is used to detect in different locations, and generate multiple touch points, and each point identification signal produced by the core point. Touch technology is FTIR (FrustratedTotalInternalReflection), the total reflection suppression.

What does multi touch screen technology bring us?

Capacitance screen with multi touch screen technology development brings us not only a new way of screen manipulation, but also enrich the interactive experience. People don't just use your fingers to simply click, and add more sliding, drag and multi-directional zoom and so on. Because of this, mobile phone products can provide more operation in the interface, bring people visual experience and fresh.

The first time to see the previous multi touch screen technology is the apple iPhone, browse the web or photos often to enlarge some part to see, iPhone pioneered the use of double finger touch zoom control mode.

Double finger zoom function is multi touch application we are most familiar with, the multi touch technology, how the application can be extended to the infinite imagination. Developers can put multitouch applications to many areas, innovative new gameplay, such as mobile phone and tablet gesture function, through the use of different the number of fingers and different sliding direction, can perform different operations or call a different interface.

Two touch? Five touch? Ten touch?

The application of multi touch screen technology is not only reflected in the daily operation of interface function, can best reflect the difference is the game experience, it let us in the "glass" on the piano has become a reality. When it comes to the game, we also have to mention, we now use the mobile phone does not use the same touch technology.

Due to the positioning of mobile phone products and cost of different products, supported by different screen multi touch screen function is different, we often see in the evaluation: the machine supports a maximum of two touch screen, the screen supports five point touch and so on, so far, mobile phone screen products up to ten point touch screen so. What are different, the upper limit of the contact screen in fact, if you understand the concept of multi touch screen technology, which is also well understood.

We have said above, the upper limit is greater, indicating that the products of the screen at the same time to identify the contact signal more, can control the possibility of rich interface is higher. In addition the most intuitive expression is in the game, some flight shooting game we need to use your fingers to control the aircraft the direction, also according to the need to click on the weapon switch and so on.

There are now more mainstream action shooting game, usually using the left hand control forward, backward and moving, right hand to control the angle of the direction and action indication, weapon switching operation and so on, some games will specially set up some more than one finger to different sliding to complete the action, of course such a complex game is the need to support multi touch technology.

Suppose we only support two touch mobile phone games, when we put two fingers on the screen at the same time, additional need to operate at third, the screen is unable to respond, compared to support more touch screen, the game experience is completely different.

We use the mobile phone is the same as in daily operation, support more contact screen, we can feel the operation process more smoothly, but on the contrary, only support the two touch screen of mobile phone often there will be some delay phenomenon. However, also reflects the positioning of this product to support the number of contacts at the same time, the flagship model of the general is the ten point touch, the mainstream models are generally five touch, relatively low-end entry-level model are the two touch, there are exceptions to the rule, but is extremely rare.

And it does profound affect our life, look back at the mobile phone product upgrading, from small screen to the big screen, from black and white to color screen screen, from the touch screen to full touch screen, mobile phone has become a small window. The world is constantly changing, various operation mode has greatly increased our use of the fun that operation has become more and more rich, more and more simple, we only need to move a finger, you can know and understand the world, of course, we must thank the multi touch screen technology, because it can bring down the touch screen mobile phone plug button smartphone. Powerful class

However, with the development of intelligent mobile phone touch screen, touch screen should not, more and more industries are in the press before the change dynasties, by adding that all changed into full touch screen operation, such as industrial equipment, medical equipment, education, automotive, building intercom, intelligent Home Furnishing, are changed into full touch screen, gestures and voice towards the future trend of development.

The difference in technology Ecclestone Howard capacitive touch screen: Gloves manipulation, waterproof control, using Corelle glass as hard as stone, the existing car do touch screen, touch screen control, intelligent Home Furnishing touch screen

Ecclestone Howard touch screen manufacturers in the multi touch screen technology is very mature, the shipment yield reached 99%, do the best quality service Tonghao touch screen the best supplier.
