Specifically, in the present embodiment, the face frame 10 is a structural frame integrally formed by an injection molding process, and may be a rectangular frame, a circular frame, or the like, and a rectangular frame is preferably used. Therefore, the middle hollow area of the face frame 10 can form the touch operation area 11, which is convenient for a finger or the stylus 100 to operate.
Referring to fig. 1 and fig. 2, the infrared device 20 is mounted on the face frame 10, and an infrared light sensing layer 30 is formed in the touch operation area 11 during operation. In one embodiment, the face frame 10 has a receiving cavity 13, that is, the face frame 10 is a hollow frame, so that the manufacturing material consumption can be reduced to reduce the cost and the weight, and the infrared module 20 is installed in the receiving cavity 13, thereby preventing the infrared module 20 from being exposed to the outside and affecting the service life and reliability. In addition, a clamping groove 14 is formed in the inner wall of the accommodating cavity 13, and the infrared component 20 is disposed in the accommodating cavity 13 and clamped in the clamping groove 14. Therefore, the infrared assembly 20 can be firmly fixed, and safe and reliable operation is ensured.
It is understood that the infrared assembly 20 includes an infrared light emitter and an infrared light receiver, and the infrared light emitted from the infrared light emitter is received by the infrared light receiver, and the infrared light covers the touch operation area 11 to form the infrared light sensing layer 30. When the stylus pen 100 or a finger is inserted into the infrared light sensing layer 30 to block the light transmission path, a sensing touch can be formed.
Further, in order to ensure reliable operation of the infrared component 20, the infrared touch panel further includes a light filtering strip 90, the face frame 10 is further provided with an open end 15, and the light filtering strip 90 is clamped at the open end 15 and seals the infrared component 20 in the accommodating cavity 13.
