[ touch display leather ]

Referring to fig. 1 to 9, which are related to embodiments of the present invention, it should be noted that the related numbers and shapes of the embodiments mentioned in the present embodiment are only used for describing the embodiments of the present invention in detail, so as to facilitate the understanding of the contents of the present invention, and not for limiting the scope of the present invention.

As shown in fig. 1 to 4, the present embodiment discloses a touch display leather E. The touch display leather E includes a touch structure 10 and a leather structure 20, and the leather structure 20 is disposed on a side surface of the touch structure 10. The touch structure 10 is configured to provide a display light source and a touch function.

When the touch structure 10 is in an activated state to provide the display light source L, the display light source L can penetrate through the leather structure 20 to display a display signal 233 (as shown in fig. 2). The display signal 233 may be, for example, a lighting signal, a text signal, a graphic signal, or a human-computer interaction interface signal, which is not limited in the present invention.

Furthermore, when the touch structure 10 is in the off state and the display light source L is not provided, the leather structure 20 can shield the touch structure 10 to present a leather pattern 232 (as shown in fig. 1).

It should be noted that, in the present embodiment, the touch structure 10 is a flexible touch structure 10, and the leather structure 20 is a flexible leather structure 20, so that the whole touch display leather E has flexibility and can be disposed on a curved object (such as the curved portions of the door trim, the roof, and the front seat back … in the automobile shown in fig. 7 to 9).

The specific structure of each component of the touch display leather E of the present embodiment will be described below, and then the connection relationship between each component of the touch display leather E will be described in due time.

Fig. 3 is a schematic cross-sectional view of fig. 1 along the line III-III. As described above, the touch structure 10 is configured to provide a display light source and a touch function.

More specifically, the touch structure 10 includes a backlight module 11 and a touch module 12. In an embodiment of the invention, the backlight module 11 is located at a bottom layer of the touch display leather E, and the touch module 12 is disposed on a side surface of the backlight module 11, but the invention is not limited thereto. For example, other components may be disposed between the backlight module 11 and the touch module 12, such as: an optical diffusion film.

Further, the backlight module 11 is configured to selectively provide a display light source L (see fig. 4). The backlight module 11 includes a backlight unit 111 and a light guide film 112, and the light guide film 112 is disposed on a side surface of the backlight unit 111. The backlight unit 111 can provide the display light source L, and the light guide film 112 can provide the display light source L penetration.

In various embodiments of the present invention, the backlight unit 111 is at least one of a Light-Emitting Diode (LED), an Organic Light-Emitting Diode (OLED), and an Electro-Luminescence (EL) sheet, but the present invention is not limited thereto. The backlight unit is suitable for use in a touch structure to provide a display light source, and the present invention is not limited thereto.

In various embodiments of the present invention, the surface of the light guiding film 112 has optical microstructures to generate a light guiding effect. Furthermore, the material of the light guide film is at least one selected from a group of materials consisting of poly (methyl methacrylate, PMMA) and Polycarbonate (PC), but the present invention is not limited thereto.

Referring to fig. 3 and 4, the touch module 12 is disposed on the backlight module 11, and the touch module 12 is configured to provide a touch function.

More specifically, in the touch structure, the touch module 12 further includes a substrate film 121 and a conductive pattern 122, and the conductive pattern 122 is disposed on a side surface of the substrate film 121 to provide the touch function.

In the embodiment, the conductive pattern 122 is disposed on a surface of the substrate film 121 opposite to the backlight unit 111, but the invention is not limited thereto. For example, in an embodiment not shown in the present invention, the conductive pattern 122 may also be disposed on a surface of the substrate film 121 close to the backlight unit 111, for example, to provide the touch function.

In various embodiments of the present invention, the material of the substrate film is at least one selected from a group consisting of Polyester (PET) and Polycarbonate (PC). Among them, polyester (polyester) is generally referred to as polyethylene terephthalate (PET). The material of the base film 121 of the present invention is not limited to the above embodiments, and any material suitable for use as the base film 121 in a touch structure is consistent with the protection spirit of the present invention, and falls within the protection scope of the present invention.

Furthermore, the conductive pattern 122 may be formed, for example, by printing a conductive ink (not shown). In a preferred embodiment of the invention, the conductive ink is a transparent conductive ink to improve the light transmittance of the touch module 12.

Referring to fig. 3 and 4, the leather structure 20 includes a diffusion layer 21, a foaming layer 22 and a fabric layer 23 stacked in sequence.

More specifically, the diffusion layer 21 is disposed on a surface of the touch module 12 opposite to the backlight module 11, and the optical powder 211 is dispersed in the diffusion layer 21 to optically diffuse the display light source L provided by the backlight module 11. The foaming layer 22 is disposed on a surface of the diffusion layer 21 opposite to the backlight module 11, and the foaming layer 22 is foamed to provide a leather feeling. Furthermore, the fabric layer 23 is disposed on a surface of the foaming layer 22 opposite to the backlight module 11, and the fabric layer is color-matched and embossed to present a leather pattern 232.

It should be noted that, although the leather structure 20 of the present embodiment is described in conjunction with the touch structure 10, the practical application of the leather structure 20 is not limited thereto. The leather structure 20 may also be a self-contained, vending product, for example, and may be applied to other types of electronic components, particularly electronic components that may provide a display light source.

According to the above arrangement, one of the main features of the present invention is that the leather structure 20 has a specially designed three-layer stack structure to generate balanced transparency and shielding.

As shown in fig. 2 and 4, when the backlight module 11 selectively provides the display light source L, the display light source L can sequentially penetrate through the touch module 12, the diffusion layer 21, the foaming layer 22 and the fabric layer 23 to display a display signal 233. It should be noted that the optical powder 211 in the diffusion layer 21 can optically diffuse the display light source L to generate an effect of atmosphere light rendering. That is, the introduction of the optical powder 211 can improve the light diffusion effect, increase the pearl effect, and adjust the light color.

Furthermore, as shown in fig. 1 and 3, when the backlight module 11 does not provide the display light source L, the leather structure 20 can shield the touch structure 10, and the leather structure 20 can present the leather pattern 232 through the fabric layer 23. That is, the leather structure 20 can generate a shielding effect when the backlight module 11 is not activated.

In various embodiments of the present invention, the base materials of the diffusion layer 21, the foaming layer 22 and the fabric layer 23 in the leather structure 20 are at least one selected from the group consisting of polyvinyl chloride (PVC), Polyurethane (PU) and Polyolefin (PO), so that the leather structure 20 can provide good light transmittance.

As used herein, the term "base material" refers to a material that is present in the layer structure in an amount of at least five or more, such that the base material is capable of assuming the form of a continuous medium and exhibiting its material properties (e.g., light transmission).

In addition, a content range of the optical powder 211 in the diffusion layer 21 is between 1.0 wt% and 30.0 wt%, preferably between 1.0 wt% and 15.0 wt%.

According to the above configuration, the diffusion layer 21 can provide a good optical diffusion effect and also have good optical transparency.

In order to provide a good leather feel and good light transmission, the foaming layer 22 is a material foamed by a foaming agent (e.g., a PU foaming agent or a PVC foaming agent).

Wherein, the ratio of the thickness of the foamed layer 22 after foaming to the thickness of the foamed layer before foaming is defined as a foaming ratio, and the foaming ratio of the foamed layer 22 is between 105% and 180%, preferably between 130% and 150%.

Wherein, the foaming layer has a thickness of 50 to 400 micrometers, preferably 200 to 400 micrometers after being foamed.

According to the above configuration, the foaming layer 22 can provide a good leather feeling and a good light transmittance.

In order to provide the visual effect of leather, the fabric layer 23 has a thickness of between 10 and 200 microns, preferably between 50 and 100 microns.

The fabric layer 23 is dispersed with a color dye 231. The color dye 231 may be at least one of an inorganic color material and an organic color material, for example. In a preferred embodiment of the present invention, the color dye 231 is a color dye with low shielding property, such as: a pigment having a nano-particle size, or a pigment having a sub-nano-particle size.

The color dye 231 is typically present in the shell layer 23 in an amount of no greater than 30 weight percent, preferably between 3 weight percent and 25 weight percent, and more preferably between 5 weight percent and 10 weight percent.

The color dye 231 typically has an average particle size between 0.05 microns and 1.50 microns, preferably between 0.2 microns and 0.7 microns.

Further, the surface of the fabric layer 23 away from the foaming layer 22 is embossed or engraved, so that the fabric layer 23 is colored and embossed to display the leather pattern 232.

According to the above configuration, the fabric layer 23 can provide the visual effect of providing leather and good light transmittance.

[ leather structure of touch display leather ]

As mentioned above, the leather structure 20 may also be a stand-alone vended product and may be applied to other types of electronic assemblies, particularly electronic assemblies that may provide a display light source.

As shown in fig. 6, the present embodiment also discloses a leather structure 20. The leather structure 20 includes a diffusion layer 21, a foaming layer 22 and a fabric layer 23 stacked in sequence. The diffusion layer 21 has optical powder 211 dispersed therein. The foaming layer 22 is disposed on the diffusion layer 21, and the foaming layer 22 is foamed to provide a leather feeling. The face fabric layer 23 is disposed on the foaming layer 22, and the face fabric layer is subjected to color matching and embossing to present a leather pattern.

The base material of the diffusion layer 21, the foaming layer 22 and the fabric layer 23 is at least one selected from the group consisting of polyvinyl chloride (PVC), Polyurethane (PU) and Polyolefin (PO), and the leather structure 20 has a visible light transmittance of 2% to 30%.
