The first portion and the second portion are arranged in a direction parallel to the display surface. The first portion is embedded in the groove at one end facing the frame, and the second portion is connected to the side of the frame opposite to the filter bar assembly 50 through the connecting portion.

[0035] Through the cooperation between the groove 105 and the first part, the filter part 55 can be stably installed in the frame without shaking. During installation, the first part can be embedded in the groove 105 at one end facing the frame, and the second part can be connected to the side of the frame opposite to the filter bar assembly 50 through the connecting part. After the filter bar is installed, the touch panel 30 can be pressed against the filter part 55 to further enhance the sealing between the filter bar and the frame, improve the waterproof performance, and improve the vibration and abnormal sound problem at the filter bar.

[0037] See also Figure 4 Furthermore, the specific shape of the groove 105 can be that the diameter of the groove body 1055 gradually decreases in the direction from the groove bottom wall 1051 to the groove opening 1057. In this way, the filter strip and the frame can form a close fit, thereby enhancing the sealing and waterproof properties.

[0038] See also Figure 5 , Figure 6 In some specific embodiments, in order to further enhance the sealing and waterproof properties, the first part and the second part form a limited notch 550, the frame part is embedded in the limited notch, the connecting part is arranged in the limited notch and is located between the filter part and the frame, and the diameter of the limited notch gradually increases from the connecting part to the touch panel. Thereby, the sealing between the filter strip and the frame is further enhanced, the waterproof performance is better, and the vibration and abnormal sound problems at the filter strip are improved. In these specific embodiments, at least part of the frame is embedded in the limited notch, and at the same time, one end of the first part facing the frame is embedded in the groove 105, further improving the sealing between the filter strip and the frame.

[0039] In some specific embodiments, the connecting portion is disposed between the limiting notch and the frame.

[0040] See also Figure 2 , Figure 5 , Figure 6The connecting portion may be specifically a second connecting portion 51, which is disposed in the limiting notch 550 and between the filter portion 55 and the frame 10, so as to facilitate installation of the filter strip. Specifically, during installation, the first portion 551 may be installed in the groove 105, and at least a portion of the frame may be embedded in the limiting notch, and the connecting portion is disposed between the filter portion and the frame.

[0041] In some specific embodiments, the filter portion 55 and the connecting portion can be integrally formed. The filter strip can be extruded. Figure 1 When the face frame assembly 100 provided in the embodiment of the present application is a face frame assembly 100 of an infrared touch display screen, the material of the filter part can be a red translucent PC material, so as to facilitate the detection of infrared light signals. The first connecting part 53 and the second connecting part 51 can be configured with TPE material, where TPE material is the general name for thermoplastic elastomers, and its full English name is Thermoplastic Elastomer. It is a type of functional material that has both rubber elasticity and plastic stiffness and can be directly injection molded. The first connecting part 53, the second connecting part 51 and the filter part can be extruded. Please combine Figure 5 , Figure 5 The figure shows the state of the filter strip assembly when it is not assembled. When it is not assembled, the first connecting portion 53 and the second connecting portion 51 are in a normal initial state. Figure 6 , Figure 6The state of the filter strip assembly after assembly is shown. After assembly, that is, the filter part and the display surface are sealed and connected by the first connection part, and the filter part and the shielding part are sealed and connected by the second connection part, the first connection part 53 and the second connection part 51 are in a compressed state. The first connection part 53 and the second connection part 51 have a tendency to restore the initial state, so that the first connection part 53 and the display surface are in interference fit, and the second connection part 51 and the shielding part are in interference fit, so as to achieve the sealing between the filter part and the display surface, and the sealing between the filter part and the shielding part, so as to achieve the effects of waterproof, dustproof, and anti-vibration and abnormal sound, and can solve the problem of failure of the touch function due to accidental water ingress, which is conducive to improving the quality and service life of the product, reducing the cost of after-sales repair and maintenance, and the appearance is good in overall appearance, beautiful and low in labor cost during the production process.

After the filter bar is installed, the touch panel 30 can be pressed toward the side of the filter part 55 to further enhance the sealing between the filter bar and the frame, improve the waterproof performance, and improve the vibration and abnormal sound problem at the filter bar. It is easy to understand that in order to ensure the touch effect and not block the touch light, the size of the filter bar assembly 50 needs to be appropriate and set according to actual requirements.

[0042] In some embodiments, the first connection portion 53 and the second connection portion 51 can be designed with a pre-compression amount (interference fit) of about 0.1 mm to 0.4 mm, specifically 0.1 mm, 0.2 mm, 0.3 mm, and 0.4 mm. When the pre-compression amount is 0.3 mm, the overall appearance is better, the touch effect is better, the sealing is good, and the waterproof performance is good.

[0044] Further, in some embodiments, the frame 10 may include a front frame, a plastic frame and a back plate arranged adjacently, and the front frame and the plastic frame may be installed side by side on the back plate, and the front frame and the back plate may be specifically screwed, clamped, etc., and the plastic frame and the back plate may be specifically screwed, clamped, etc. The touch panel 30 may be bonded to the plastic frame, for example, the touch panel 30 is fixed to the plastic frame by double-sided tape. During installation, the first part 551 of the filter portion 55 may be embedded in the groove 105, and the other end of the filter portion 55 is sealed and connected to the display surface of the touch panel 30 through the first connecting portion. The infrared touch control component 70 is assembled in the front frame, and the four sides of the front frame are screwed to the back plate. It is also possible to tighten the bolts after installing the filter strip, so that the plastic frame presses the touch panel 30 to one side of the filter portion 55, and the first connecting portion 53 and the second connecting portion 51 are squeezed by the front frame and the touch panel 30 to form a close fit, further enhancing the sealing between the filter strip and the frame, and having better waterproof performance, and improving the vibration and abnormal sound problems at the filter strip.
