What is the scientific name of the large glass touch screen in the real estate sales center? How doe

This one you're talking about should be a near-field imaging touchscreen. The sensing mechanism of the near-field imaging touch screen is two laminated glasses with a transparent metal oxide conductive coating in the middle. An AC signal is applied to the conductive coating, which creates an electrostatic field on the surface of the screen.

When a finger or other conductor comes into contact with the sensor, the electrostatic field is disturbed. The accompanying image processing controller can detect this interference signal and its position and transmit the corresponding coordinate parameters to the operating system. The near-field imaging touch screen is very durable, the sensitivity is very good, and it can be used in very harsh environments and public places, but its disadvantage is that it is more expensive.

It can be a capacitive screen or an infrared screen.

It is a kind of touch technology, called touch film, which has no touch function on the glass itself, and a piece of film is pasted on it.

You're talking about a touch film, and the interface is the glass used.

First of all, you understand how the computer mouse operates the computer, and then install a pressure-sensitive, or thermal-sensitive sensor at the bottom of the computer screen, and convert the touch command into a command like a mouse click.

I won't copy

Those professional stuff too. Touch screens are divided into resistive and capacitive, each with its own advantages and disadvantages, and the principle is also different! Why can the touch screen be touched, because there is a layer under the touch screen and the internal connection of the mobile phone, which refers to the resistive touch screen, so that the screen will respond when you tap it.

I don't remember the specific names of those layers, I just looked at the principle of the touch screen, as for the capacitive type, it only reacts when it comes to contact, so it is not equipped with a stylus, and there are others (gradually phased out).

The main elements of a mobile phone's touch screen are a sensor unit that processes the user's selection, a controller that senses touch and localizes it, and a software driver that transmits the touch signal to the operating system. These three types of components make up the working mechanism of the touch screen. In addition to the components, there are several types of technology such as capacitive touch screen, resistive touch screen, infrared touch screen, surface acoustic wave touch screen, and near-field imaging touch screen.

At present, the most widely used mobile phone touch screen is capacitive touch screen.

The working principle of capacitive touch screen: it uses the current induction of the human body to work. When the user touches the screen, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance, which is a direct conductor for high-frequency currents, so the finger sucks a small current from the contact point.

This current is drawn from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance of the finger to the four corners, and the controller obtains the position of the touch point by accurately calculating the proportion of these four currents.

There will be some interference factors in the use of the mobile phone touch screen, such as electrostatic discharge, strong magnetic field, oil, sweat, water vapor and other conductive substances attached to the screen, which may permanently damage the capacitive screen. When the ambient temperature and humidity do not meet the working environment, or the voltage is low and unstable, physical impact and vibration and other factors will cause damage to the capacitive touch screen, resulting in the scrapping of the capacitive screen. Therefore, it is necessary to test the touch screen of the mobile phone.

Selecting the appropriate test module in the test can play a good connection function, and can play an excellent role in the on-current and transmission signal. The high-current shrapnel microneedle module can be suitable for mobile phone touch screen testing, and the one-piece structural design is made of nickel alloy beryllium copper material, which has tough performance, is not easy to break the needle, has a high service life, and has strong overcurrent capacity, which can solve the problem of mobile phone touch screen testing.

The temperature of your fingers, it can feel it. So there will be a reaction. Poking with a ballpoint pen will not work. Generally only the temperature of your finger is recognized.

Look what form of touch screen you want to know, touch screen is divided into capacitive and resistive, the principle of capacitive screen is to use the human body as an electrode of a capacitor element, when there is a conductor close to the mezzanine ITO working surface coupling a capacitance with sufficient capacitance value, (finger contact and the screen to form a capacitance) between the capacitance between the finger and the screen changes to obtain touch information. Resistive touch screen is basically a thin film plus glass structure, when touched, the ITO of the lower layer of the film will contact the ITO of the upper layer of glass, fingers press the screen, the distance between the two screens changes, resulting in the change of screen resistance value, a message is sent out through the sensor, and then sent from the controller to the computer, through the driver to convert to the X and Y values on the screen, and complete the action of clicking, and present on the screen. The resistive touch screen can only judge one touch point at a time when working, and if the touch point is more than two, it cannot make a correct judgment, so the resistive touch screen is only suitable for the judgment of some simple actions such as clicking and dragging.

The multi-touch of the capacitive touch screen can decompose the user's touch into two tasks: collecting multi-point signals and judging the meaning of the signal, and complete the judgment of complex actions, which is one of the reasons why most mobile phones now use capacitive screens.

Capacitive touch screen When a person is not in contact with a touch screen, the electrodes are of the same potential. However, when a finger is touched to a capacitive touchscreen, a coupling capacitance is formed between the human electric field, the fingers, and the conductor layer, and the electrodes on all four sides emit an electric current that flows to the contacts. Theoretically, the current flowing through the four electrodes is proportional to the distance from the finger to the four corners, and the controller calculates the contact point position by calculating the proportions of the four currents.

When we touch the screen with our fingers or other objects, the two conductive layers inside the resistive touch screen are in contact, and the resistance changes, and the controller can judge the coordinates of the contact point according to the specific change of resistance and operate accordingly.

The developers are selling first-hand real estate, and the sales are good. The commission is about 2 1000-3 1000.

Most of the intermediary sales are second-hand houses, which require experience.

The salary of real estate sales is basic salary + commission, and the basic salary is generally only more than 1,000 yuan.

If you want to earn money, you can choose a residential project. If you want to learn marketing, you must do commercial real estate.

Finally, the real estate industry is relatively ruthless, deceitful, and courageous, and you need to be cautious when getting started.

CWMW: Have you ever seen an infrared, capacitive, and surface-wave mobile phone touch screen?

If it's a simple Ctrl+C or Ctrl+V action, anyone can do it, and it's better to take a little responsibility to the questioner.

Touch screen bai (touch screen.

The working principle is composed of a touch detection component and a touch screen controller; The touch-sensitive detection part is installed in the display genus.

In front of the screen, it is used to detect the user's touch position and accept the touch screen controller; The main function of the touch screen controller is to receive touch information from the touch point detection device, convert it into contact coordinates, and then send it to the CPU, which can also receive the commands sent by the CPU and execute them.
