[0003] For example, an anti-blue light capacitive touch screen with the authorization announcement number "CN206741155U" solves the problem of the existing anti-blue light capacitive touch screen having a very poor overall blue light blocking effect. The light emitted by the LCD backlight layer being energized is filtered by the anti-blue light film layer and then passes through the ITO layer, the glue layer, and the glass cover layer in turn before irradiating out to block the blue light. Considering the existing anti-blue light capacitive touch screen, the anti-blue light film layer during use is completely installed inside the anti-blue light capacitive touch screen, so that the anti-blue light film layer cannot be replaced according to usage requirements, resulting in the anti-blue light effect being unable to be replaced according to usage requirements, and being unable to meet the use of a wide range of users.

The FPC is also called a soft circuit board or a flexible circuit board. It has excellent characteristics such as light weight, thin thickness, and free bending and folding. An IC10 is installed inside the FPC9. The IC10 is an integrated circuit formed by placing a large number of microelectronic components such as transistors, anodes, and capacitors on a plastic base to make a chip. A groove 305 is installed on the inner wall of the housing 1.

[0026] Working principle:

[0027] Use phase

[0028] When the finger touches the transparent glass 6 on the shell 1, the touch sensor 11 at the lower end of the transparent glass 6 contacts the finger, the connecting line 8 supplies power to the display screen 7 and displays the content, and the FPC (flexible circuit board) and IC control at the output end of the touch sensor 11 change the display content on the display screen 7.

[0029] Anti-blue light effect

[0030] After a certain period of use, the sealing strip 302 can be manually pressed, and the fixing block 303 on the sealing strip 302 can be separated from the shell 1. The required anti-blue light film 304 can be placed between the glass 6 and the touch sensor 11 using tweezers without residue, so as to absorb and intercept the blue light in the bright light emitted by the display screen 7 and avoid damage to the eyeglass tissue.

[0031] Protection Phase

[0032] The outer wall of the shell 1 has opposite first and second protrusions 401 and 403 connected to the protective shell 402. When external force contacts the protective shell 402, the first and second protrusions 401 and 403 made of rubber are deformed to absorb the force of the outer wall of the protective shell 402, thereby achieving a certain protection effect on the display screen 7 and the touch sensor 11 inside the shell 1.
