Capacitive touch screens are designed with a remarkable principle that allows them to last indefinitely with proper care and no intentional damage. This means that as long as the screen is commissioned without any issues, it can continue to be used without any worries about its lifespan. While there are no specific regulations regarding the life of these screens, most manufacturers pledge at least 50 million touches before any potential issues may arise. Furthermore, the industry standard warranty period for these touch screens is typically one year, providing peace of mind for any potential concerns during the initial stages of use.

Starting from Windows 7, Microsoft has implemented a drive-free system for newer versions, although the driver still needs to be installed on Windows Home editions. However, for earlier versions of Windows, drivers were required to be loaded manually. These drivers typically only supported single-point touch and required loading for Android and various versions of Linux such as Ubuntu, Debian, SuSE (openSuSE), Fedora Core, Mandriva, and Slackware. Moreover, installing these drivers required cooperation and modifications from motherboard manufacturers to adjust the base parameters.

To provide these drivers and support for different operating systems, our company would need to employ base development engineers. Unfortunately, our current ILITEK solution does not support any operating systems, while our EETI solution can only support single-point touch. Nonetheless, we are committed to continuously improving our technology and exploring new possibilities to offer the best products and services to our customers.

The anti-interference of capacitive touch screens is determined by the design of the SENSOR circuit and control IC. If the design is reasonable and standardized, and the IC is reasonably selected, this situation can be avoided.

Under normal circumstances, the broken line is due to the damage (open circuit and short circuit) of the SENSOR line. Our company has specially added protection to the SENSOR line, preventing this from happening. Touchpoint jumping or mistouch is generally due to the high sensitivity of the touch program, which can be solved by appropriately reducing the sensitivity.

A single capacitive touch screen typically has a program. After the whole machine is assembled, the program will be commissioned, which will be the perfect one.

The thickness of the cover plate is more than 3mm, which is made of toughened glass. After the assembly of the cover glass and the capacitive touch sensor glass, it is anti-burst. The specific anti-burst grade can be adjusted reasonably according to customer requirements.

Our capacitive touch screen is composed as follows: COVER 3mm + glue thickness 0.2 mm + SENSOR 1.1 mm. The thickness of COVER and glue can be increased to improve the anti-burst ability of the screen. 

This is mainly due to the following reasons:

 A. the system does not support the screen, and drivers need to be installed;

 B. There is a problem with the wire contact, or the wires are reversely connected; 

C. FPC or control board of the capacitive touch screen is damaged. 

Special attention should be paid during installation:
1. The minimum installation interval between the capacitive touch screen and the LCD screen is 1MM (after compression). It is recommended to assemble them with non-conductive double-sided foam.
The foam used should be acid-free and non-corrosive.

2.The capacitive touch screen and LCD screen should be placed horizontally before the assembly of the whole machine.

3. The FPC of the capacitive touch screen should be separate from the metal frame.

 This is mainly due to the following reasons:
A. The principle of capacitive touch screens;
B. Other processing (line graphics) can be used in the design stage, which can reduce the touch sensitivity of the back of the screen but cannot eliminate the sensitivity;
C. As long as attention is paid to the distance between the capacitive touch screen and LCD screen during the whole machine assembly. It will be normal in function.

The sensitivity can be adjusted, and the response time of the touch screen is ≤ 10 milliseconds. The system response time can also be adjusted.

The resolution of our capacitive touch screen is 4096*4096. The accuracy of the capacitive touch screen is reflected by the number of channels. The more channels (TX and RX), the smaller they will be. Generally, the channel of the capacitive touch screen is designed according to the size of human fingers, which is usually 4.5 ~ 7.2 mm.
