What's the screen
From portable excellent mobile phones to larger tablets on the screen, from late launch of touchy nokia to htc, which is the pilot of touchy cell phones, the screen has been immersed in a variety of products. Everything was so quiet, the machine with the electric screen was being pushed to the user's attention, and although the screen was not widely publicized or popular, it seemed to be accepted for granted. There's no one new on the screen, but are you really familiar with it
A lot of people are passive recipients of electric screens, because they find that almost one day, whether a mobile phone or a tablet, a domestic brand or a foreign firm, has introduced their own electric screen type, that users have no other space to choose, and that, together with a really good telekinesis, they just walk in vaguely, as if everyone knew it, and that a lot of people are not familiar with it。
What's the screen
What is a screen is a fundamental question, but it will not be explored by too many people, and many users know that it is very easy to use, rather than voluntarily understand it. However, it is precisely because of the lack of knowledge that many people are asking why this type of machine is not equipped with handwritten pens and so on when buying a cell phone。

First of all, look at the construction of the screen, which consists mainly of a transparent membrane layer on the screen, as well as a protective glass outside the catheter layer, which is good for protecting the conductor layer and sensors. The screens should work using human electric influenza, and when users touch the screens, the human electric field, the user's finger and the surface of the touch screen form a condensed condensation. At this point, the cell phone controller calculates the currents from your fingers to the four corners of the screen in a precise manner and gives an accurate position of up to 99%. The use of human electron influenza to achieve touch manipulation is the main feature of the screen。
Overview of screen development
As touch-made products move along, the good or bad way to touch also determines whether a machine experience is good or not. The screen has also been mainstreamed, with a more smooth and better touch-and-control sense than traditional resistance. In the future, it is not just mobile phones and tablets that use screens, such as smart television or laptops, which are also expected to be connected to screens, which are easily visible。

What's the difference with the screen
It is a mere description of how the screen works itself and of how it is developed, and it is not compared to traditional resistance screens. It is believed that many people remain vague about these two ways of touching, although they are all touching, but the difference is much worse. The screens are applied by the power-driven principle, which is applied by human current-driven principles。

The difference between the two can be illustrated by an example in which the ect screen can only be touched by the skin of the human being, and the use of nails or other hard matter is totally unworkable, as it is related to its operation, and the human body can form an electric current and not other objects. The screen, on the other hand, can be touched by hand-written pens or other things, and it can be touched as long as the object is able to put some pressure on it, that is to say, the working method of the barrier-touching requires external force。
Electro-screen barrier distinction
Modus operandi: the electricity is dependent on human currents and requires skin contact
The resistance is pressured by external force
Advantages and disadvantages: capacitation supports multi-touch, priced but mainstream
It's more resistant
At present, most of the resist screen phones are of a national nature because of their location and the price of their sale, and most of these types are designed to use the resist touch screen. The screen is not vulnerable to objective conditions such as the environment or temperature, and many users are used to hand-written input for the population, and the screen is still performing relatively well in this regard, and it is not just a complete absence that can be seen。
The screen is mainly focused on smartphones or high-end products, although, as it is widely used today, it is not all in high-priced form, and it is now available at 2000 or even 1,000. Transient and smooth manipulation and multi-touch technical support are making the screen increasingly acceptable。
What factors affect the screen
What factors affect the screen
While the screen is mainstream, it itself is more “smuggling” and its own shortcomings are obvious compared to the barrier. Nothing is perfect, and it's not a bone picking in an electric touch screen egg, but it's an attempt to tell you the whole picture of it, so that you can learn more about it. Several of the shortcomings of the electric screens are reflected mainly in the following aspects。

The reflection is serious: the reflection of the screen is more serious, but it does not have a disproportionate effect on the day-to-day behaviour of users, which we can avoid. However, in addition to the reflections, there is a problem of colour distortion due to the uneven light penetration of the four layers of composite touch screens of the electro-capacitation technology to the wavelengths, and the reflections of the light between the layers can easily lead to the blurry of image characters。
Permissible operation: the advantage of the screen is that it is responsive, but when there is a conductor close to the interface with the layer ito working surface, the current flow is sufficient to trigger the wrong movement of the screen. That is to say, when a living object that can produce an electrical flu response approaches the screen, even if it does not touch the screen, it causes the screen to move wrongly。
Drifting: the phenomenon of drift is a problem that many users complain about. When the temperature and humidity of the environment change, and when the electric field changes in the surrounding environment, it causes the screen to drift, resulting in an inaccuracy of touch accuracy. It is more vulnerable to the conditions surrounding it, which is less resilient than the barrier。
Factors affecting the screen
Excessively low temperature: the screen is sensitive to temperature, and excessive or low temperatures affect the ability to feel
Sweat or drops of water: sweat or drops of water on your finger and then touch it, it's easy to form a conductor on the screen and drift
Too close to the magnetic field: magnetic objects such as soundboxes are easier to disable and avoid frequent exposure to magnetic objects
Most afraid of voltage instability: electricity screens drift when the voltage is unstable
The electrostatic shock is very powerful: it is easy for humans or clothing to be electrostatic in winter, and it is easy to strike through the cell phone screen
