Can a normal monitor be made into a touch screen?

Yes, you can. But the effect is poor.

1. Because it is an ordinary LCD screen, you need to buy a piezoelectric film and paste it on your screen, link the piezoelectric film with the PC host, and calibrate the touch position, so that it can barely be used.

Second, there is a problem, an ordinary LCD display can not be squeezed, a hard screen is required, or a screen protective glass needs to be added between the screen and the piezoelectric film.

3. In general, this solution can only be usable, and the effect is very poor.

Recommendation: Buy a touchscreen monitor directly.

Yes, but you need to install a touchscreen module. A touchscreen module is a pluggable electronic device that typically contains a transparent sensing layer and a controller that makes it touch-enabled by mounting it on a normal computer display.

To convert a normal computer display to a touch screen, you need to first purchase a touch screen module for that type of display and make sure that it is compatible with the computer display interface. Then, according to the module manual, the installation and set-up are carried out, and the touch screen function can be used after commissioning.

It should be noted that since the installation of the touch screen module requires the disassembly of the shell of the computer display, it is necessary to have certain electronic equipment maintenance skills and installation experience to avoid unnecessary damage to the equipment during operation. At the same time, unofficial modifications may void the warranty of the device, so please consider it carefully.

Yes, the resolution will be very low, and the effect will be worse.

Problem description: It is said that the LCD display should not be touched by hand. Is there any harm in touching it?

Analysis: There is a special coating on the surface of the LCD panel, which can prevent reflection and increase the best effect. Although the manufacturer has strengthened the panel itself and the coating, it still can't stand some people's "stinky problem" - used to touch the LCD screen with their hands, there is a certain corrosive grease on people's hands, which will slightly corrode the coating of the panel, and it will cause permanent damage to the panel for a long time.

This damaged panel will have a mottled feeling in use.

In addition, some people like to press the panel by hand, which is very interesting. It's definitely a bad habit, and it can lead to dead pixels and dark spots, which are permanent damage and can never be repaired!

1.Touch screen is referred to as TP, which is generally used to respond to human touch events.

2.The display screen is generally used for display, and the commonly used ones are LCD, OLED, etc.

3.In mobile phones, the touch screen and display are made together. It looks like this screen is both a touch screen and a display, but it's not.

The mobile phone screen is generally made into 2 layers, and the upper layer (outer layer) is a touch screen, which is used for touching, and is generally transparent, requiring good light transmittance. The lower layer (inner layer) is the display screen, which is used for display.

To sum up, the image we usually see is displayed on the inner display, but it is seen through the touch screen.

Note: 1) There are 2 types of touch screens: resistive and capacitive. The relationship between the touch screen and people is very close, and now the commonly used cover is the capacitive pants touch screen.

2) Application fields of touch screen: mobile phones, (tablet) computers, etc.

To modify a touch monitor from an ordinary monitor, you need to install a layer of "transparent panel" for positioning in front of the display, and then install the corresponding driver. The existing touch screen also implements touch control by integrating a positioning panel.

The touch screen mainly has the following modes:

Resistive (double-layer);

Surface capacitive;

Inductive capacitive;

surface acoustic wave;

Infrared; bending wave type;

Active digitizer type;

Optical imaging.

The above modes are divided into two categories, the first three touch screens require the use of ITO, and the other structures do not require the use of ITO.

Nowadays, common touch displays are realized by using a control board made of TIO coated glass + ITO film.

If you have the energy to DIY, buy a touch screen connected to the monitor, and you can meet your requirements.

Kind, open the back cover and there is a knob that can be turned, just adjust it. Don't do it yourself, there is a high-pressure bag inside. Dangerous!

Buy a touch screen, install it between the panel of the monitor and the screen, and connect the corresponding cables. ok

Not kidding you, it's true.
