Why are today s mobile phones all touch screens?

When choosing a touch screen, you should consider many factors. Here are some tips for buying and hoping it will be helpful to you. 1. When you get a touch screen, look at whether there is a green border printed around the touch screen, if so, you can probably guess that it is insulating ink, but insulating ink may also be translucent color.

In any case, the design with insulating inks will be slightly lower than the quality of double-sided tapes with a substrate. 2. You can see the design of the line end, if the place where the tail of the line is connected to the touch screen itself is not enough, the touch screen is easy to break, and the touch screen has little chance of repairing if it is broken. 3. You can hold the touch screen in your hand and use 60 angles to see if there is a Newton ring on the surface, if there is a touch screen generated by a Newton ring, it means that the factory has insufficient experience in dealing with Newton rings.

4. Press with your fingers....

Smart + touch + large screen is the mainstream of the times, the operation experience is no longer a copycat touch screen for several years, and the multi-point capacitive screen will make you feel good about it.

Hope it helps, hope.

Touchscreens are already trendy. Pay attention to whether it is a capacitive screen or a resistive screen, the capacitive screen is sensitive, and you can get used to it and type it quickly with an input method that suits you.

It's good to have a keyboard, but there is no touch screen beautiful, generous, fashionable, and everyone has a love for beauty.

If you are using a Huawei phone, the touch screen automatically jumps or touches the screen, you can use the following methods to troubleshoot the operation:

1.If the problem of jumping or ghost hands occurs when charging only in a fixed place, it may be caused by the unstable power supply voltage, and it is recommended that you change the charging to another place (replace the power supply).

2.If there is a problem of random jumping and ghost hands when charging only with a third-party charging device, please use the standard charger and data cable to try to charge first, if there is no problem, it may be a problem with the third-party charging equipment; It is recommended that you use the original charger in scenarios where you need to charge and use touch control, and you can remove the protective case to improve the touch experience.

3.Please check whether there is a microwave oven, induction cooker and other high-intensity magnetic fields nearby, which will cause interference to electronic components, resulting in abnormalities such as random jumping of the touch screen;

4.Please scroll down the status bar to view it in the shortcut settings menu, or search and enter NFC in the settings to check whether the NFC function is enabled, and NFC will automatically open the specified application after scanning out a specific scene.

5.Please check whether you have installed the "one-key lock screen" type application, some third-party "one-key lock screen" software will conflict with the system's built-in lock screen, resulting in random jumps, such as jumping to the lock screen interface, camera interface, etc. It is recommended to uninstall third-party software such as "one-click lock screen".

If the above methods still do not solve your problem, we recommend that you back up important data in advance (third-party communication apps must be backed up separately) and bring your phone, standard charger, data cable, and relevant purchase credentials to a nearby Huawei customer service center for testing.

The mobile phone screen is always automatically triggered in one place, if it is not in the case of charging, so that you can suspect that it is a problem with the touch screen or the internal cable of the mobile phone, you can send it to after-sales testing, and if necessary, you can choose to change the screen.

The mobile phone screen is always a place, and the problem of your own touch screen means that your touch screen is not working and invalid, so this situation will occur.

It's very simple, buy a lighter, remove the discharged one, and charge it to the place where the screen has been pointed, and mine is so good.

That could be your phone screen is broken.

1. One-click acceleration to clear background programs.

If there are too many background programs, or there are abnormal programs in the background that may affect the touch screen effect, it is recommended that you speed up or clean up background programs with one click before trying again.

Note: Check if it is installed"One-click lock screen.

"The software will conflict with the lock screen that comes with the system, resulting in random jumps, such as jumping to the lock screen, etc., it is recommended to uninstall the third party"One-click lock screen. "and other types of software.

2. Whether there is liquid or stain on the finger or screen.

Liquid or stains on your fingers or screen will affect the sensitivity of the touchscreen, so it is recommended to clean it with a clean, dry cloth before trying again.

3. Check the film.

If you use a non-original film, it may affect the touch screen effect, so we recommend that you remove the film or go to the customer service center to reapply the film.

4. Replace the standard charger or data cable.

If you use a charger that does not come as standard, it may affect the phone's touch screen function while charging, so it is recommended that you use the standard charger and cable for charging.

5. Restart your phone.

Please restart your phone or force restart your phone to see if it returns to normal.

Force Restart Method:

Models released before September 2017 (models before x20): Press and hold"Power button"More than 12 seconds.

Models released after September 2017 and new models released later (x20 and later): Press and hold at the same time"Power button"+"Volume down key"More than 10 seconds.

NEX 3 NEX 3S: Press and hold the top round button for more than 10 seconds.

6. Upgrade the system version.

The new version improves compatibility and stability, and can be viewed by upgrading the system.

7. Reset all settings.

Reset all settings and follow the on-screen prompts.

Note: Restoring all settings will not delete any data or ** files, only all settings of the phone will be restored, some third-party application accounts need to be logged in again, please confirm that it does not affect the use of the software before operating, if there is important information, it is recommended that you can also back it up in advance.

8. Service center testing.

If the above methods fail to solve your problem, please back up your mobile phone data in advance, bring your mobile phone and purchase voucher to vivo customer service center for testing, pay attention to WeChat *** "vivo" or "vivo customer service" to inquire about the service center address**, it is recommended to contact before going to ensure that there is a staff reception before going over, so as to avoid delaying precious time and running in vain.

If the phone has a situation where the touch screen is not sensitive and malfunctions, it is recommended:

1.Check if the phone has a film, if there is a suggestion to cancel the screen film and try it.

2.If the touch screen of the mobile phone is completely malfunctioning, it is recommended that you restart the machine and observe it again.

3.Try to update the system version of your phone (Note: Please back up the data in your device before upgrading).

4.If it doesn't work, back up the data in your device (contacts, text messages, **, etc.) and try to restore factory settings.

If the problem persists after the above operations, it is recommended that you bring the machine, purchase invoice, and repair card to the local Samsung after-sales service center for testing.

My mobile phone's touch screen failed, what should I do if I just bought the Sonai LT15i for less than half a month, the touch screen failed twice, both when playing games while charging, as long as I unplugged the charger, it was fine, whether it was a mobile phone problem or a game problem.

Because it is the finger contact that forms the capacitance with the screen, the capacitance between the finger and the screen changes to obtain touch information.

1. Capacitive touch screen technology uses the current induction of the human body to work. The capacitive touch screen is a four-layer composite glass screen, the inner surface and the interlayer of the glass screen are each coated with a layer of ITO, the outermost layer is a thin layer of silicone glass protective layer, the laminated ITO coating is used as the working surface, four electrodes are drawn out at the four corners, and the inner layer ITO is the shielding layer to ensure a good working environment.

2. When the finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitor, for high-frequency current, the capacitor is a direct conductor, so the finger sucks a small current from the contact point.

The working principle of resistive touch screen is mainly through the principle of pressure sensing to achieve the operation and control of the screen content, this touch screen body part is a multi-layer composite film that is very compatible with the surface of the display, in which the first layer is the bottom layer of glass or plexiglass, the second layer is the partition layer, the third layer is the surface layer of multiple resins, and the surface is also coated with a transparent conductive layer.

It is then covered with a layer of smooth, scratch-resistant plastic with a hardened outer surface. The conductive layer and glass layer sensor on the surface of the polylipid surface are separated by many tiny compartments, and when the surface layer is pressed down, the controller simultaneously reads the corresponding current from the four corners and calculates the distance of the finger position.

This type of touch screen uses two highly transparent conductive layers to form a touch screen, with the distance between the two layers being only microns. When the finger touches the screen, the two conductive layers that are usually insulated from each other have a contact at the touch point, because one of the conductive layers is connected to a uniform voltage field of 5V in the direction of the y-axis, so that the voltage of the detection layer changes from zero to non-zero.

After the controller detects this connection, it converts the A D and compares the obtained voltage value with 5V, which can obtain the Y-axis coordinates of the touch point, and the X-axis coordinates are obtained in the same way, which is the most basic principle common to all resistive technology touch screens.

With the increasing development of human science and technology, people's quality of life is constantly improving, so in our daily life, everywhere you can see is that everyone has at least one mobile phone, from the previous button mobile phone to the current touch screen mobile phone, and for the current touch screen mobile phone, we will be more curious,Why can a person's finger touch a mobile phone screen? In fact, it is mainly due to the relationship between the composition materials of the mobile phone.

Most of the mobile phones we use now are capacitive touch screens, and when people touch the mobile phone screen with their fingers, the metal inside the mobile phone screen will produce a kind of capacitance, and the generation of capacitance means that there is a current inside the mobile phone, and this current will flow between the various parts of the mobile phone, and this current will be dispersed from the mobile phone screen to each part, so that the current can be calculated from which location, so we will find, After we touch the screen of the corresponding software with our fingers, the screen will pop up the corresponding pop-up box, and the corresponding APP will open, so people's fingers can only touch the mobile phone screen and react, mainly due to the capacitance generated by the screen when touching.

In the past, the mobile phone is still a button, but there is a resistive touch screen behind, although this represents another progress in science and technology, compared with the capacitive screen, the resistive touch screen has a relatively large obstacle, so most of the mobile phones with touch screen are basically capacitive screens, so now most people's fingers can touch the screen, and the mobile phone screen is caused by capacitance.

Although we basically have a mobile phone for everyone now, we also have to pay attention to the precautions for the use of mobile phones, for example, for the screen, we should be careful not to drop water and some oil droplets on the screen, otherwise this may lead to the touch of the screen is not sensitive, mainly because water on the screen will also lead to the generation of capacitorsBecause the reason why people's fingers can touch the screen of the mobile phone is mainly because the mobile phone will produce capacitance during the process of finger touching.

Because human fingers have a certain amount of bioelectric energy, human fingers can touch the screen of a mobile phone.

Because today's touchscreen mobile phones use capacitive screens, when fingers touch different positions of the capacitive screen, different currents will be generated and transmitted to each mobile phone part.

Because today's mobile phone screens are all touch screens, feedback can be achieved through human operation.
