Touch screen is widely used in modern electronic technology production,Its excellent performance replaces the traditional glass screen,Touch screen technology is also constantly being tapped,I will explain the installation and disassembly skills of the touch screen in detail today.

Disassembly touch screen precautions

When removing the CRT,Do not grab or collide with the neck and electron gun of the CRT.Because the electron gun is a glass structure,Very easy to be broken,

Repair the touch screen front cover       

After removing the CRT and the front cover of the touch screen,Try putting the touch screen into the removed touch screen front cover,Generally, some ribs are designed inside the front cover.These ribs are mainly useful when demolding during production,If it interferes with the touch screen or feels long-term use, it may damage the wires on the edge of the touch screen, It should be cut off with a diagonal pliers.

Applying a dust-proof strip to the front cover of the touch screen has two functions:1.Prevent crushing the transducer. Some touch screens such as PHILIPS front cover are not high enough,If the dust is not attached to the touch screen loaded strip will transducer is crushed, resulting in not using the touch screen。

2.Prevent outside dust from entering the touch screen stripe area,If there is too much dust on the touch screen stripe, the touch response will be slow, and the local touch will be invalid.Applying a dust-proof strip can effectively solve this problem.

Apply double-sided tape. Apply double-sided tape to the visible area of the picture tube. When the touch screen is pasted, peel off the double-sided tape.

Reinstall the touch screen. Because the thickness of the touch screen and double-sided tape is increased between the original screen and the front cover, some rubber gaskets should be added when installing the CRT. Then put the picture tube into the front cover, connect the connection lines, lead the screen line or the serial line, and reinstall and fix the display.

Installing the touch screen precautions

If the front cover of the display is placed flat on the workbench and then the picture tube is installed in the front cover of the display, the lower part of the front cover of the display must be raised so that the touch screen does not directly touch the workbench because the surface of the touch screen is curved, otherwise it is extremely easy. Crush the touch screen during installation!

The height of the rubber gasket should be slightly higher than the total height of the touch screen and double-sided tape.

When loading the picture tube into the front cover of the monitor, pay attention to the position of the mounting hole on the positive tube and the front cover mounting hole of the touch screen. Otherwise, the touch screen image will be tilted and the installation work will be
