This design not only demonstrates the company's R&D strength in the field of touch technology, but also broadens the scope of application of the product, so that it can be widely used in various electronic products, meeting the needs of different customers, thereby enhancing the company's market competitiveness;

[0037] The FPC body 1 has button touch, which is mainly realized by integrating capacitive sensors and control circuits. The capacitive screen board is a screen that uses the capacitive sensing principle to realize the touch function. It is widely used in FPC to improve its flexibility and application scope. The working principle of the capacitive screen board is based on the capacitive sensing principle. The response speed to the charge is very fast, and it can realize accurate multi-touch and gesture recognition. By using the capacitive screen board on the FPC body 1, the user can perform various operations by touching a specific area on the screen, such as clicking, sliding, zooming, etc. to realize the touch button function.

[0038] Further, such as Figure 1-Figure 2 As shown, a key panel portion is provided on one side of the FPC body 1 away from the light guide plate body 201. The light guide plate is an optical element, and its design principle is derived from the liquid crystal display screen of a laptop computer. It is a high-tech product that converts a line light source into a surface light source. It uses an optical-grade acrylic / PC sheet as a substrate, and uses a high-tech material with an extremely high refractive index and no light absorption, and prints light guide points on the bottom surface of the sheet by laser engraving, V-shaped cross grid engraving, UV screen printing technology, etc.; when light is emitted from the LED lamp 2 and irradiated onto the light guide plate, it stays on the surface of the light guide plate and shines on each light guide point. These light guide points will diffuse the reflected light to various angles, destroy the reflection conditions, and make the light emitted from the front of the light guide plate. By designing light guide points of different densities and sizes, the light guide plate can emit light evenly, and the reflective sheet is used to reflect the light exposed from the bottom surface back into the light guide plate to improve the efficiency of light use.

[0039] Further, such as Figure 1-Figure 3As shown, the key panel portion includes a black light-shielding double-sided adhesive 4 arranged on a side of the FPC body 1 away from the OCA double-sided adhesive 202, and a plurality of key pattern holes 401 are arranged on the black light-shielding double-sided adhesive 4.

[0041] Appearance and aesthetics: The translucent black tempered glass 5 has a deep black color, which provides a unique and beautiful appearance for this application. This color not only has a modern feel, but also matches the shell and design style of various devices, enhancing the overall beauty;

[0042] Durability and hardness: The translucent black tempered glass 5 has high hardness and wear resistance, which can effectively prevent scratches and wear in daily use, can ensure the long service life of this application, and reduce the performance degradation or appearance damage caused by wear;

[0043] The translucent black tempered glass 5 has excellent touch performance, which can ensure that users get a smooth and accurate touch experience when using it. The material of the translucent black tempered glass 5 has good conductivity, which can ensure the accurate transmission of touch signals and reduce false touches and delays.
