For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacturing, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. The relative term may refer to a plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. A numerical value without a relative term should also be disclosed as a particular value having a tolerance. In addition, "substantially" when expressing a relative angular positional relationship (e.g., substantially parallel, substantially perpendicular) may refer to a plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0036] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0037] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as a limitation on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that orientation terms such as upper side, lower side, left side, right side, front side, rear side, etc. not only represent the positive orientation, but can also be understood as the side orientation. For example, below can include directly below, lower left, lower right, lower front, and lower rear, etc.

[0038] Please refer to Figures 1 to 4, this embodiment provides an infrared touch screen, which includes a panel glass 1, a filter strip 3, an outer frame 4, and a lamp board 5. The filter strip 3 includes a working part 31 and a connecting part 32. The working part 31 is disposed on the display surface of the panel glass 1, and the connecting part 32 is disposed on the side surface of the panel glass 1. The outer frame 4 is connected to the working part 31 and / or the connecting part 32. The lamp board 5 is disposed on the outer frame 4 and is located on one side of the panel glass 1. The lamp board 5 is configured to emit infrared signals toward the working part 31, or receive infrared signals conducted through the working part 31.

[0039] It can be understood that the outer frame 4 is connected to the working part 31 disposed on the display surface of the panel glass 1 and / or the connecting part 32 disposed on the side surface of the panel glass 1, which can enable the back surface of the filter strip 3 to be in direct contact with the panel glass 1, thereby shortening the distance between the surface of the filter strip 3 and the surface of the panel glass 1. That is to say, it can shorten the touch depth of the infrared touch screen, and further contribute to reducing the overall thickness of the infrared touch screen and improving the user experience. It can also be understood that shortening the touch depth of the infrared touch screen can also reduce the height of the touch sensing area formed on the surface of the panel glass 1, thereby helping to reduce the possibility of false touch and further improving the accuracy of touch recognition. In addition, the overall thickness of the infrared touch screen is thinner, and the aesthetics is better.

[0040] To make the connection between the filter strip 3 and the outer frame 4 more reliable, in this embodiment, the outer frame 4 is connected to the working part 31 and the connecting part 32. Specifically, the outer frame 4 and the working part 31 are snap-connected through a first snap component 6, and the outer frame 4 and the connecting part 32 are snap-connected through a second snap component 7.

[0041] In addition, the structures of the first snap component 6 and the second snap component 7 are the same. Hereinafter, the structure of the first snap component 6 will be described as an example. The first snap component 6 includes a snap block 61 and a snap groove 62 that can be adaptively snap-connected. The snap block 61 and the snap groove 62 are respectively disposed on the outer frame 4 and the working part 31. In this embodiment, the snap block 61 is integrally formed on the working part 31, and the snap groove 62 is disposed on the outer frame 4. It can be understood that the snap structure composed of the snap block 61 and the snap groove 62 has a simple structure, reliable connection, and is more convenient for assembling the infrared touch screen.

[0042] Generally speaking, the lamp board 5 is usually arranged on the outer frame 4 so that the lamp board 5 is closer to the light filtering strip 3. In this embodiment, the outer frame 4 includes an installation groove 41 for accommodating the lamp board 5, and the light filtering strip 3 can close the notch of the installation groove 41. With such a setting, the convenience of assembling the infrared touch screen can be further improved. Correspondingly, the emitting end of the lamp board 5 extends out of the notch and is close to the light filtering strip 3, so that the lamp board 5 can better emit or receive infrared signals, and further improve the accuracy of touch recognition. It should be noted that, in this embodiment, the outer frame 4 is made by aluminum extrusion molding technology. With such a setting, on the one hand, the production efficiency of the outer frame 4 can be improved, and on the other hand, the quality stability of the outer frame 4 can be ensured. It should also be noted that the installation groove 41 is formed by surrounding the outer frame 4, with a simple structure and low production cost.

[0043] To improve the stability of the lamp board 5 after assembly, the lamp board 5 and the groove wall of the installation groove 41 are clamped by at least one third clamping component 8. It should be noted that, in this embodiment, the structure of the third clamping component 8 is the same as that of the first clamping component 6 described above, and will not be elaborated here. To further improve the stability of the lamp board 5 after assembly, both opposite sides of the lamp board 5 are connected to the groove wall of the installation groove 41 through the third clamping component 8.

[0044] To improve the convenience of assembling the light filtering strip 3, the working part 31 and the connecting part 32 surround a positioning groove 33 that can be clamped with the edge of the panel glass 1. With such a setting, it is more convenient to correspond the installation position of the light filtering strip 3 with that of the panel glass 1. It can be understood that the light filtering strip 3 only cooperates with the edge of the panel glass 1, with a small contact area, which can make the combined structure of the light filtering strip 3 and the outer frame 4 provided in this embodiment have strong applicability. For example, it can be applied to common infrared full lamination and infrared zero lamination solutions in the field, and can also be applied to DLED and ELED display backlight solutions, which will not be elaborated here. It should be noted that, in this embodiment, the light filtering strip 3 is made by plastic extrusion molding technology. With such a setting, on the one hand, the production efficiency of the light filtering strip 3 can be improved, and on the other hand, the quality stability of the light filtering strip 3 can be ensured. In addition, the color of the light filtering strip 3 is preferably tea-colored semi-transparent.

[0045] The infrared touch screen further includes a support member 2. The support member 2 includes a support portion 21 and a supporting portion 22. The support portion 21 is used to support the panel glass 1, and the supporting portion 22 is used to support the side of the outer frame 4 facing away from the light filtering strip 3, so as to improve the structural stability of the infrared touch display. It should be pointed out that, in this embodiment, the support member 2 is selected as a support bar in the prior art, and the support portion 21 and the supporting portion 22 are respectively the two sides of the support bar.

[0046] This embodiment further provides an infrared touch device. The infrared touch device includes the above-mentioned infrared touch screen and a frame (not shown in the figure), and the infrared touch screen is disposed on the frame. It can be understood that for the infrared touch device including the above infrared touch screen, the user experience is better.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
