[0021] In order to facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0022] Please refer to Figures 1 to 2, A touch button panel 10 includes: a glass cover plate 100, a light-shielding adhesive layer 200, a touch FPC 300, an adhesive layer 400, and a diffusion film 500 arranged in sequence. A first hollow area 310 and a button area 320 are formed on the touch FPC 300. A second hollow area 210 and a third hollow area 220 are formed on the light-shielding adhesive layer 200. A fourth hollow area 410 is formed on the adhesive layer 400. The first hollow area 310 and the second hollow area 210 are arranged opposite to each other. A light sensor IC 600 is arranged on one side of the first hollow area 310 away from the second hollow area 210. The button area 320 is arranged opposite to the third hollow area 220 and the fourth hollow area 410.

[0023] It should be noted that by arranging the button area 320 opposite to the third hollow area 220 and the fourth hollow area 410, the light passes through the diffusion film 500, the fourth hollow area 410, the button area 320, and the third hollow area 220 in sequence and irradiates onto the glass cover plate 100, making the buttons on the touch button panel 10 have a light-emitting effect. A button touch pattern is made on the button area 320. The shape of the third hollow area 220 is the same as the shape of the button touch pattern. The light-shielding adhesive layer 200 shields the excess light, enabling the user to see the buttons more clearly and avoiding the situation of unclear buttons. By arranging the first hollow area 310 opposite to the second hollow area 210, the light sensor IC 600 can sense the change in the ambient light intensity, thereby adjusting the button brightness so that the user can clearly see the buttons in a darker environment, meeting the user's needs.

[0024] Please refer to again Figure 1 , In one embodiment, a PI reinforcement plate 211 is arranged on the second hollow area 210. The PI reinforcement plate 211 can provide more stable support for the light sensor IC 600, ensure the firm installation of the light sensor IC 600 at the specified position, and prevent the light sensor IC 600 from moving or falling off due to the flexibility of the touch FPC 300.

[0025] Please refer to again Figure 1 , In one embodiment, a light-transmitting hole 212 is formed on the PI reinforcement plate 211. The light-transmitting hole 212 is arranged opposite to the first hollow area 310. Thus, it can be avoided that the PI reinforcement plate 211 blocks the light sensor IC 600, ensuring that the light sensor IC 600 can sense the change in the ambient light intensity.

[0026] Please refer to again Figure 1 , In one embodiment, the light-shielding adhesive layer 200 is a black double-sided adhesive. With such a setting, while adhering the touch FPC 300 to the glass cover plate 100, the light-shielding adhesive layer 200 also provides a light-shielding function, avoiding the situation of unclear buttons.

[0027] Please refer to again Figure 1, In one embodiment, the glass cover plate 100 is a semi-transparent black tempered glass plate. With this arrangement, the glass cover plate 100 can prevent the light of the keys from diverging, making the clarity of the keys better, and at the same time enhancing the strength of the touch key panel 10.

[0028] Please refer to again Figure 1 , In one embodiment, the size of the glass cover plate 100 is the same as that of the light-shielding adhesive layer 200. With this arrangement, it is more conducive to firmly bonding the glass cover plate 100 and the touch FPC 300 through the light-shielding adhesive layer 200, preventing detachment and displacement.

[0029] Please refer to again Figure 2 , In one embodiment, an IC component area 330 is provided on the touch FPC 300. The IC component area 330 is connected to the circuit on the touch FPC 300, enabling signal transmission and improving the reliability of the touch key panel 10.

[0030] Please refer to again Figure 2 , In one embodiment, an FPC plug interface 340 is provided on the touch FPC 300. The touch FPC 300 is connected to other components through the FPC plug interface 340.

[0031] Please refer to again Figure 2 , In one embodiment, a PI reinforcement sheet 350 is provided on the touch FPC 300. The PI reinforcement sheet 350 is disposed on one side of the FPC plug interface 340, enhancing the strength at the FPC plug interface 340 and making the connection between the touch FPC 300 and other components more stable.

[0032] In one embodiment, an anti-fouling film is provided on the glass cover plate 100, preventing the surface of the touch key panel 10 from being soiled and affecting the function of the keys, thus reducing the user experience.

[0033] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
