The contact surface in this embodiment includes the surface and the side surface of the display panel 1.

According to the invention, the rubber pad 3 is arranged between the contact surfaces of the display panel 1 and the infrared touch frame assembly 2, so that the force generated by collision between the display panel 1 and the frame 21 of the infrared touch frame assembly 2 in the assembling process is buffered, and the possibility of breakage of the display panel 1 caused by collision is further reduced; meanwhile, the display panel 1 can be prevented from being broken in the transportation and use processes, and the shockproof effect of the whole machine is improved; in addition, through set up rubber pad 3 between display panel 1 and infrared touch-control frame subassembly 2's contact surface, can also prevent effectively that water and dust from getting into the organism inside to guarantee and prolong the life-span of the inside device of complete machine.

It should be noted that, in the above-mentioned embodiment of the infrared touch display, only the above-mentioned structure is described, and some necessary prior art structures are not described in detail, and it is understood that, besides the above-mentioned structure, the infrared touch display according to the embodiment of the present invention may further include any other structure as needed, for example, in the embodiment of the present invention, the infrared touch frame assembly 2 further includes the light filtering bar 22 and the infrared PCB 23; the infrared PCB 23 is arranged in the inner cavity of the frame 21; the infrared PCB 23 is also provided with an infrared transmitting tube and an infrared receiving tube (which can be arranged at equal intervals); the infrared transmitting tubes and the infrared receiving tubes are arranged along four sides of the display panel 1 and form infrared matrixes which are crossed horizontally and vertically in a corresponding mode (the infrared transmitting tubes and the infrared receiving tubes are in one-to-one correspondence); the light filtering strip 22 is arranged on the frame 21 and is positioned on the light path of the infrared transmitting tube and the infrared receiving tube, and is used for filtering and trimming light rays. As another example, in the embodiment of the present invention, the display panel 1 may be an OLED display panel or an LCD display panel.

In the present embodiment, a display panel 1 is taken as an example of an LCD display panel, where the display panel 1 includes a glass 11, a liquid crystal panel 12 and a backlight assembly 13; wherein: the liquid crystal panel 12 is disposed between the glass 11 and the backlight assembly 13 and is fixedly connected to the glass 11 and the backlight assembly 13, respectively, and the glass 11 is located at the outermost portion of the infrared touch display and is used for protecting the liquid crystal panel 12 and the backlight assembly 13.

In some embodiments of the present invention, the rubber pad 3 is fixedly connected to the display panel 1 or the bezel 21. For example, the rubber pad 3 may be fixedly attached to the edge of the glass 11 of the display panel 1, or fixedly attached to the frame 21 where the display panel 1 contacts, to protect the surface and side of the glass 11. But is easier to handle when attached to the display panel 1 than when attached to the bezel 21, making the assembly process easier and easier.

In some embodiments of the present invention, the rubber pad 3 may be fixed by an adhesive 31, such as various adhesives, such as double-sided adhesive tape, glue, adhesive tape, etc.

Referring to fig. 2, in some embodiments of the present invention, an adhesive 31 may be pre-disposed on the rubber pad 3, so as to facilitate the assembling operation and save the assembling time. In addition, the adhesive 31 may be selectively adhered to one surface of the rubber pad 3 according to the specific application, or the adhesive 31 may be adhered to both surfaces of the rubber pad 3, so as to obtain a better effect of fixing the glass 11 and the frame 21. In addition, the rubber pad 3 can be provided with a back adhesive in advance, so that the pasting operation is convenient, and the time is saved.

Referring to fig. 3, in some embodiments of the present invention, the number of the rubber pads 3 may be four, and the four rubber pads are respectively disposed on four sides of the display panel 1 (glass 11), or respectively disposed on the frame 21 at positions corresponding to the four sides of the display panel 1 (glass 11), in which case the effects of anti-breaking, anti-vibration, waterproof and dustproof are the best. The number of rubber pads 3 is 4, which is the best effect, but the present invention does not exclude the case of using a smaller number of rubber pads 3, and the number of rubber pads 3 may be reduced according to the actual situation, but the effects of vibration-proof, water-proof and dust-proof are accordingly reduced.

The rubber pad 3 is made of rubber materials, has good elasticity, corrosion resistance, wear resistance and other effects, can obtain good shock absorption, water resistance and dust resistance, has long service life, is beneficial to protecting the infrared touch display and prolongs the service life of the whole machine.

Matching in the following embodiments refers to complementary shapes, which may allow for a complete or substantial fit/abutment between the contacting surfaces of two objects.

Referring to fig. 1 and 2, in some embodiments of the present invention, the rubber pad 3 has a strip-shaped structure; the rubber pad 3 has a surface shape matching at least one of the display panel 1 and the bezel 21. For example, the shape of the surface of the rubber pad 3 that is attached to the display panel 1 matches the shape of the display panel 1, and the shape of the surface of the rubber pad 3 that is attached to the frame 21 matches the shape of the frame 21. Of course, one of the upper and lower surfaces (the surface to be bonded to the frame 21 and the surface to be bonded to the display panel 1) of the rubber gasket 3 may be selected to match the shape of the member to be bonded depending on the mounting position of the rubber gasket 3, but the vibration damping effect of this embodiment is slightly inferior to that of the embodiment matching the shapes of the display panel 1 and the frame 21 at the same time. In the case where the surface shape of the rubber pad 3 matches both the display panel 1 and the frame 21, the upper and lower surfaces (the surface attached to the frame 21 and the surface attached to the display panel 1) of the rubber pad 3 may have the same shape or different shapes. For example, in the practical application process, in order to facilitate the assembly, the shape of the contact portion between the frame 21 and the glass 11 is usually designed to be matched (for example, the edge of the glass 11 is right-angled, and the right-angled portion of the frame 21 that is fastened to the glass 11 is also designed), and therefore, in order to make the frame 21 better fit to the glass 11 to obtain a better shock absorption effect, for example, the shape of the surface (body surface) of the rubber pad 3 that contacts the glass 11 is designed to be matched with the shape of the edge of the glass 11, and the shape of the surface (body surface) of the rubber pad 3 that contacts the frame 21 is designed to be matched with the shape of the frame 21, so that the shapes of both surfaces of the rubber pad 3 are the same; if the shape of the contact surface of the glass 11 and the frame 21 may not be completely matched due to other requirements, the rubber pad 3 may be adjusted accordingly, for example, the shape of the surface (body surface) of the rubber pad 3 contacting the glass 11 is designed to match the shape of the edge of the glass 11, and the shape of the surface (body surface) of the rubber pad 3 contacting the frame 21 is designed to match the shape of the frame 21, so that the shapes of the two surfaces of the rubber pad 3 may be different.

Referring to fig. 1, 2, 4 to 6, in some embodiments of the present invention, the rubber pad 3 is a strip-shaped structure; the cross section of the rubber pad 3 is L-shaped, arc-shaped or U-shaped.

As shown in fig. 1 and 2, the glass 11 of the display panel 1 is processed into a plate-shaped structure, and the upper surface of the glass is at right angles to the side surface, and in order to obtain better adhesion effect with the display panel 1 and the frame 21, the rubber pad 3 may be a strip-shaped structure with an L-shaped cross section as shown in fig. 1 and 2, and the structure can obtain better effects of preventing breakage, shock, water and dust.

Referring to fig. 4, in another embodiment of the present invention, the edge of the uppermost glass 11 of the display panel 1 may be processed into another shape, such as a chamfer on the edge of the glass 11, in fig. 4, the edge of the glass 11 is processed into an arc chamfer, and accordingly, in order to better fit the glass 11, the surface of the rubber pad 3 that is attached to the edge of the glass 11 may be processed into a shape that matches the surface of the edge of the glass 11, such as an arc.

Referring to fig. 5, the edge of the glass 11 may be beveled, and accordingly, for better fit, the surface of the rubber pad 3 that is engaged with the edge of the glass 11 may be shaped to match the surface of the edge of the glass 11.

Referring to fig. 6, the rubber pad 3 may be further configured to have a U-shaped cross section, and the shape of the U-shaped groove wall for better fitting and fixing the U-shaped structure may be matched with the shape of the edge surface (upper surface, lower surface, and side surface) of the glass 11, and the rubber pad 3 is only required to be fastened and fixed on the glass 11 during installation.

Example 2

Referring to fig. 7 to fig. 13, the second embodiment of the present invention is different from the first embodiment in that: in this embodiment, the surface of the rubber pad 3 is provided with protrusions 32. The protrusions 32 in this embodiment can increase the friction between the rubber pad 3 and the glass 11 and between the rubber pad 3 and the frame 21, so that the rubber pad 3 can be well fixed between the display panel 1 and the frame 21 under the pressure fit of the frame 21, and further, the mode of fixing and bonding through the bonding object 31 is replaced, and the processing cost can be further reduced.

Referring to FIG. 7, in some embodiments of the invention, the shape of the protrusion 32 may be a half-circle; referring to fig. 8, the shape of the protrusion 32 may also be cylindrical; referring to fig. 9, the shape of the protrusion 32 may also be conical; referring to fig. 10, the protrusion 32 may also be shaped as an elongated body; the present embodiment merely illustrates the shapes of the protrusions 32, and the shapes of the protrusions 32 are not limited thereto in the present invention, and may be other shapes. The shape of the protrusions 32 is shown in fig. 7-10 by way of example only, and the protrusions 32 are not fully spread over the surface of the rubber pad 3 in the drawing, and the protrusions 32 may be provided at other contact surfaces as well, and the process is omitted in fig. 7-10.

In the embodiment of the present invention, please refer to fig. 11, the position of the protrusion 32 may be disposed on a surface of the rubber pad 3 contacting the display panel 1; referring to fig. 12, the position of the protrusion 32 may also be set on the side contacting the frame 21; referring to fig. 13, the position of the protrusion 32 can also be set on both sides. Wherein two sides set up its effect of increasing friction simultaneously better, do benefit to fixedly more.

It should be noted that the size, the laying density, the laying area, and the laying arrangement of the protrusions 32 can be adjusted according to the friction force required by the actual application, and the present invention is not limited thereto. For example, the protrusions 32 may be formed to cover the surface of the rubber pad 3, or may be formed only partially. The protrusions 32 may be arranged regularly or irregularly, but the regular arrangement may make the friction between the rubber pad 3 and the display panel 1 and between the rubber pad 3 and the frame 21 more uniform, and the fixing effect is better.
