Description

Technical Field

[0001] The utility model relates to a touch technology, in particular to an anti-ultraviolet film touch screen and a vehicle-mounted code meter module. Background Art

[0002] With the development of intelligent technology, intelligence can be seen everywhere in people's lives. Products such as motorcycles, bicycles, and toy cars are also equipped with display screens to display information such as speed, maps, and altitude. At present, the touch screen of the on-board meter module generally adopts two structures: GG structure and GFF structure.

[0003] Among them, the GG structure refers to a double-layer glass structure formed by making the touch sensor circuit on a glass substrate and then bonding the glass substrate and the glass cover plate. This structural design product is very thick and heavy, and the vibration effect is not good; but it has good UV resistance and is currently the most commonly used structure for car-mounted meter modules.

[0004] The GFF structure refers to a single-layer glass structure formed by making the touch sensor circuit on a film sheet and then laminating the film sheet with the glass cover. This structural design product is thin, light, and has good vibration effect; but the UV resistance is poor. The film sheet will turn yellow under long-term UV exposure, affecting the display effect. However, in cycling competitions, this type of structure is often used to pursue lightweight and increase speed.

[0005] Therefore, a new design is needed to improve the UV resistance of the GFF structure touch screen. Utility Model Content

[0006] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides an anti-ultraviolet film touch screen, which can improve the UV radiation resistance performance of the GFF structure touch screen.

[0007] The utility model also provides a vehicle-mounted code meter module, comprising the above-mentioned anti-ultraviolet film touch screen.

[0008] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0009] An anti-ultraviolet film touch screen comprises a glass cover plate and a touch film, wherein the touch film is attached to one side surface of the glass cover plate, and an ultraviolet cut-off functional layer is arranged on one side surface of the glass cover plate.

[0010] Furthermore, the UV cutoff functional layer is a UV cutoff film or a UV cutoff coating.

[0011] Furthermore, the ultraviolet cutoff functional layer is formed by alternately stacking multiple SiO2 layers and multiple Nb2O5 layers.

[0012] Furthermore, the thickness of each SiO2 layer and each Nb2O5 layer is 10 to 70 nm.

[0013] Furthermore, the total thickness of the SiO2 layer and the Nb2O5 layer is 600 to 1000 nm.

[0014] Furthermore, the anti-ultraviolet film touch screen further includes a first OCA glue, and the touch film is adhered to one side surface of the glass cover plate through the first OCA glue.

[0015] Furthermore, the touch film includes a first film sheet having a first touch sensing circuit and a second film sheet having a second touch sensing circuit, the first film sheet being adhered to a side surface of the glass cover plate, and the second film sheet being adhered to a side surface of the first film sheet facing away from the glass cover plate.

[0016] Furthermore, the anti-ultraviolet film touch screen further includes a second OCA adhesive, and the second film sheet is adhered to a surface of the first film sheet which is away from the glass cover plate through the second OCA adhesive.

[0017] A vehicle-mounted code meter module comprises a display screen and the above-mentioned anti-ultraviolet film touch screen, wherein the display screen is attached to the touch side surface of the anti-ultraviolet film touch screen.

[0018] Furthermore, the vehicle-mounted code computer module also includes a third OCA glue, and the display screen is adhered to the touch side surface of the anti-UV film touch screen through the third OCA glue.

[0019] The utility model has the following beneficial effects: the touch film is formed, and then the touch film and the glass cover plate are relatively attached to each other to form a single-layer glass GFF structure, which has the advantages of thin thickness, light weight, and good vibration effect; at the same time, an ultraviolet cut-off functional layer for cutting and filtering ultraviolet rays is arranged on one side surface of the glass cover plate to prevent ultraviolet rays from irradiating the touch film after passing through the glass cover plate, so as to avoid the film membrane of the touch film from being irradiated by ultraviolet rays for a long time and turning yellow, thereby improving the UV irradiation resistance performance of the GFF structure touch screen.

[0028] like Figure 1 As shown, an anti-ultraviolet film touch screen comprises a glass cover plate 1 and a touch film 4, wherein the touch film 4 is attached to one side surface of the glass cover plate 1, and an ultraviolet cut-off functional layer 2 is provided on one side surface of the glass cover plate 1.

[0029] The utility model anti-ultraviolet film touch screen firstly makes a touch sensing circuit on a film membrane to form the touch film 4, and then relatively fits the touch film 4 with the glass cover plate 1 to form a GFF structure of a single-layer glass, which has the advantages of thin thickness, light weight and good vibration effect; at the same time, an ultraviolet cut-off functional layer 2 for cutting and filtering ultraviolet rays is arranged on one side surface of the glass cover plate 1 to prevent ultraviolet rays from irradiating the touch film 4 after passing through the glass cover plate 1, so as to avoid the film membrane of the touch film 4 from being irradiated with ultraviolet rays for a long time and turning yellow, thereby improving the UV irradiation resistance performance of the GFF structure touch screen.

[0030] The film sheet will be photodegraded under ultraviolet irradiation, which will cause yellowing on the surface of the material. Specifically, the film sheet has a structure of benzene rings and ester groups, which easily absorbs ultraviolet rays and generates free radicals. The ester group part continues to generate free radicals under the attack of free radicals, and the free radicals react with oxygen molecules in the air to form peroxy radicals, which in turn cause the ester group part to break bonds, produce derivatives such as carboxylic acids, and finally cause yellowing.

[0031] In this embodiment, the film sheet is a PET (polyethylene terephthalate) film sheet, and the touch sensing circuit is an ITO sensing circuit or a silver paste sensing circuit.

[0032] The ultraviolet cutoff functional layer 2 is an ultraviolet cutoff film or an ultraviolet cutoff coating.

[0033] The UV cutoff film is prepared by forming a UV cutoff material on a transparent film by magnetron sputtering or spraying, and the UV cutoff film is adhered to one side surface of the glass cover plate 1 by OCA glue; the UV cutoff coating is prepared by directly forming a UV cutoff material on the glass cover plate 1 by magnetron sputtering or spraying, without a film substrate, smaller thickness, and no problems such as film bubbles.

[0034] If the UV cutoff functional layer 2 adopts a UV cutoff film, the UV cutoff film can be attached to the surface of the glass cover plate 1 facing the side, or attached to the surface of the glass cover plate 1 facing away from the touch film 4; if the UV cutoff functional layer 2 adopts a UV cutoff coating, the UV cutoff coating is preferably formed on the surface of the glass cover plate 1 facing the touch film 4 to prevent scratches by foreign objects.

[0035] like Figure 2 As shown, the ultraviolet cut-off functional layer 2 is formed by alternately stacking multiple SiO2 layers 21 and multiple Nb2O5 layers 22.

[0036] Of the SiO2 layer 21 and the Nb2O5 layer 22, one is a low refractive index layer and the other is a high refractive index layer. When ultraviolet rays are irradiated on the interface between the SiO2 layer 21 and the Nb2O5 layer 22, reflection and refraction will occur. The reflected and refracted ultraviolet rays will interfere with each other and then partially offset each other, thereby weakening the ultraviolet rays. The more layers of the SiO2 layer 21 and the Nb2O5 layer 22 there are, the more times the ultraviolet rays interfere with each other, and the stronger the ultraviolet cutoff filtering ability of the ultraviolet cutoff film will be.

[0037] The thickness of each SiO2 layer 21 and each Nb2O5 layer 22 is 10-70 nm, and the total thickness of the SiO2 layer 21 and the Nb2O5 layer 22 is 600-1000 nm.

[0038] The anti-ultraviolet film touch screen further includes a first OCA glue 3 , and the touch film 4 is adhered to a side surface of the glass cover plate 1 through the first OCA glue 3 . Embodiment 2

[0039] As an optimization solution of the first embodiment, in this embodiment, if Figure 3 As shown, the touch film 4 includes a first film sheet 42 having a first touch sensing circuit 41 and a second film sheet 45 having a second touch sensing circuit 44. The first film sheet 42 is attached to a side surface of the glass cover plate 1, and the second film sheet 45 is attached to a side surface of the first film sheet 42 facing away from the glass cover plate 1.

[0040] The first touch sensing circuit 41 and the second touch sensing circuit 44 may both adopt ITO sensing circuits, or both adopt silver paste sensing circuits, or one may adopt an ITO sensing circuit and the other may adopt a silver paste sensing circuit.

[0041] The first touch sensing circuit 41 is used to sense a touch position in an X direction, and the second touch sensing circuit 44 is used to sense a touch position in a Y direction, where the X direction is perpendicular to the Y direction.

[0042] The anti-ultraviolet film touch screen further includes a second OCA glue 43 , and the second film sheet 45 is attached to the surface of the first film sheet 42 on one side facing away from the glass cover plate 1 through the second OCA glue 43 . Embodiment 3

[0043] like Figure 4 As shown, a vehicle-mounted code computer module includes a display screen 6 and the anti-ultraviolet film touch screen described in the first or second embodiment, wherein the display screen 6 is attached to the touch side surface of the anti-ultraviolet film touch screen.

[0044] The vehicle-mounted code computer module further includes a third OCA glue 5 , and the display screen 6 is adhered to the touch side surface of the anti-ultraviolet film touch screen through the third OCA glue 5 .

[0045] In this embodiment, the display screen 6 is a segment code screen, and the segment code screen has a plurality of segment code patterns, and each segment code pattern is combined to form a fixed display pattern.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
