Description

Decorative panel and touch device

The present invention relates to a decorative component and an electronic device, and more particularly to a decorative panel and a touch device.

In recent years, with the development of the technology industry, handheld electronic devices such as smart phones or tablet computers have been widely used in daily life. The use of these handheld electronic devices is becoming more common and is moving toward a convenient, versatile and aesthetically pleasing design. When consumers purchase these handheld electronic devices, the aesthetics of the design has gradually become an important factor in addition to the hardware and software functions.

Taking the smart phone in a handheld electronic device as an example, the appearance of the traditional black and white border can no longer meet the needs of consumers. Therefore, how to make the smart phone frame have a specified color to enhance the product value has become one of the important topics of current research and development personnel. In the prior art, a manufacturer uses a printed method to form a plurality of decorative layers on a substrate to have a designated color of the smartphone frame. However, the more decorative layers are printed, the higher the chance of print offset between the decorative layers. Example In the case that after the first decorative layer is formed on the substrate, if the second decorative layer is formed on the first decorative layer with a small predetermined contraction distance, the second decorative layer is easy to exceed the first when the printing tolerance is large. Decorative layer, not conducive to the production of smart phones.

The invention provides a decorative panel and a touch device, which can allow a large predetermined retraction distance between the decorative layers and have good shielding properties.

A decorative panel of the present invention includes a first substrate, a first decorative layer, a second decorative layer, and a first light shielding layer. The first substrate has a light transmitting region and a peripheral region outside the light transmitting region. The first decorative layer is disposed on a peripheral region of the first substrate. The second decorative layer is disposed on the peripheral region of the first substrate. The first decorative layer is located between the second decorative layer and the first substrate. The first light shielding layer is disposed on a peripheral area of the first substrate. The second decorative layer is located between the first light shielding layer and the first decorative layer. The first decorative layer, the second decorative layer, and the first light shielding layer respectively have a first decorative opening, a second decorative opening, and a third decorative opening exposing the light transmissive area and overlapping. The orthographic projection of the second decorative opening on the first substrate completely covers the orthographic projection of the first decorative opening on the first substrate. The first decorative layer and the second decorative layer are stacked in one direction. The thickness of the first decorative layer in this direction is greater than the thickness of the second decorative layer in this direction.

In the decorative panel and the touch device according to the embodiment of the present invention, since the thickness of the first decorative layer is greater than the thickness of the second decorative layer, the second decorative layer may be formed on the first decorative layer by a predetermined predetermined contraction distance. In addition, the problem that the second decorative layer in the prior art is easily exceeded beyond the first decorative layer is improved. The reason is that even if it is scheduled The retraction distance is large, so that the first decorative layer has more regions protruding outside the second decorative layer, but because the thickness of the first decorative layer is larger (that is, the optical density of the first decorative layer is higher), the convex The first decorative layer extending beyond the second decorative layer still provides sufficient shielding properties, thereby making the decorative structure less prone to color fretting.

1 is a cross-sectional view of a decorative panel in accordance with an embodiment of the present invention. Referring to FIG. 1 , the decorative panel 100 includes a first substrate 110 , a first decorative layer 120 , a second decorative layer 130 , and a first light shielding layer 140 . The first decorative layer 120, the second decorative layer 130, and the first light shielding layer 140 constitute a decorative structure S. The first substrate 110 has a light transmitting area AA and a peripheral area BB outside the light transmitting area AA. It should be noted that the present invention is not limited Whether or not the peripheral region BB of the first substrate 110 is transparent. In this embodiment, when the decorative structure S is disposed in the peripheral area BB of the first substrate 110, the area of the decorative panel 100 that overlaps with the peripheral area BB is opaque. It is also mentioned that the present invention does not limit the peripheral area BB to surround the light transmitting area AA. In other embodiments, the peripheral region BB may be disposed on at least one side of the light-transmitting region AA, in other words, the first and second decorative layers 120, 130 and the first light-shielding layer 140 may be disposed on one side of the light-transmitting region AA, and It is not necessary to present a ring configuration. Therefore, the present invention also does not limit the first decorative opening 120a of the first decorative layer 120, the second decorative opening 130a of the second decorative layer 130, and the third decorative opening 140a of the first light shielding layer 140 must be closed, in other In the embodiment, the first decorative opening 120a, the second decorative opening 130a, and the third decorative opening 140a may also be open.

The first decorative layer 120 and the second decorative layer 130 are disposed on the peripheral region BB of the first substrate 110. The first decorative layer 120 is located between the second decorative layer 130 and the first substrate 110. The first light shielding layer 140 is disposed on the peripheral region BB of the first substrate 110. The second decorative layer 130 is located between the first light shielding layer 140 and the first decorative layer 120. The optical density (OD) of the first light shielding layer 140 is greater than the optical density of the first decorative layer 120 and the optical density of the second decorative layer 130. The first decorative layer 120, the second decorative layer 130, and the first light shielding layer 140 respectively have a first decorative opening 120a, a second decorative opening 130a, and a third decorative opening 140a that overlap the light transmitting area AA and overlap. In this embodiment, the first decorative opening 120a, the second decorative opening 130a, and the third decorative opening 140a are used to expose the touch element structure. The orthographic projection of the third decorative opening 140a on the first substrate 110 completely covers the orthographic projection of the first decorative opening 120a on the first substrate 110 and the second decorative opening 130a is on the first substrate 110. Orthographic projection on. The orthographic projection of the second decorative opening 130a on the first substrate 110 completely covers the orthographic projection of the first decorative opening 120a on the first substrate 110.

It is to be noted that the first decorative layer 120 and the second decorative layer 130 are stacked in the direction d. The thickness T1 of the first decorative layer 120 in the direction d is greater than the thickness T2 of the second decorative layer 130 in the direction d. From another point of view, the thickness T1 of the first decorative layer 120 in the direction d, the thickness T2 of the second decorative layer 130 in the direction d, and the thickness T3 of the first light-shielding layer 140 in the direction d are Tt, Among them, 0.04 ≦ (T3/Tt) ≦ 0.35. By using the technical means that the thickness T1 of the first decorative layer 120 is greater than the thickness T2 of the second decorative layer 130, the second decorative layer 130 can be formed on the first decorative layer 120 with a larger predetermined contraction distance L, and the conventional technique is improved. The middle second decorative layer tends to exceed the problem of the first decorative layer. The reason is that even if the predetermined retraction distance L is large, the first decorative layer 120 has more regions protruding outside the second decorative layer 130, since the thickness T1 of the first decorative layer 120 is larger (ie, the first decoration) The optical density of the layer 120 is relatively high, and the first decorative layer 120 protruding from the second decorative layer 130 can still provide sufficient shielding property, thereby making the decorative structure S less susceptible to color sudden changes. The following is explained by comparison between FIG. 1 and FIG. 2.

2 is a schematic cross-sectional view of a decorative panel of a comparative example. Referring to FIG. 2 , the decorative panel 10 of FIG. 2 includes a substrate 1 and a first decorative layer 2 , a second decorative layer 3 , and a first light shielding layer 4 stacked on the substrate 1 in sequence. The first decorative layer 2, the second decorative layer 3, and the first light shielding layer 4 constitute a decorative structure S'. The decorative panel 10 of Fig. 2 is similar to the decorative panel 100 of Fig. 1, except that in the decorative panel 10, the thickness T1' of the first decorative layer 2 is equal to the thickness T2' of the second decorative layer 3. Assume first The transmittance of the decorative layer 2 and the second decorative layer 3 is 70%, and the transmittance of the decorative structure S' in the region K1 of the first decorative layer 2 protruding from the second decorative layer 3 is 70%, and the decoration is The transmittance of the structure S' in the region K2 where the first decorative layer 2 and the second decorative layer 3 are overlapped and exposed by the first light shielding layer 4 is 49% (that is, the transmittance of the first decorative layer 2 is 70% multiplied by the first The transmittance of the second decorative layer 3 is 70%). The transmittance of the decorative structure S' from the region K1 to the region K2 was changed to 21% (i.e., the transmittance of the region K1 was 70% minus the transmittance of the region K2 by 49%). Referring to FIG. 1 , it is assumed that the transmittances of the first decorative layer 120 and the second decorative layer 130 are respectively 35% and 70% (ie, the thickness T1 of the first decorative layer 120 is twice the thickness T2 of the second decorative layer 130). The transmittance of the decorative structure S in the region M1 of the first decorative layer 120 protruding from the second decorative layer 130 is 35%, and the first decorative layer 120 and the second decorative layer 130 are overlapped by the first light shielding layer. The transmittance of the exposed region M2 of 140 is 24.5% (i.e., the transmittance of the first decorative layer 120 is 70% multiplied by the transmittance of the second decorative layer 130 by 35%). The transmittance of the decorative structure S from the region M1 to the region M2 was changed to 10.5% (i.e., the transmittance of the region M1 was 35% minus the transmittance of the region M2 by 24.5%). Comparing the change in transmittance of the decorative structure S' of FIG. 2 from the region K1 to the region K2 (ie, 21%) and the change in transmittance of the decorative structure S of FIG. 1 from the region M1 to the region M2 (ie, 10.5%), When the thickness T1 of the first decorative layer 120 is greater than the thickness T2 of the second decorative layer 130, the change in the transmittance of the decorative structure S from the region M1 to the region M2 is small, and the problem of sudden color change is less likely to occur.

In addition, as shown in FIG. 1 , a thicker first decorative layer 120 is used to form a decorative layer (ie, the second decorative layer 130 ) and a light shielding layer (ie, the first layer) in the subsequent process of the decorative panel 100 . a light shielding layer 140) can make the decorative structure S have a foot The optical density value is sufficient without increasing the number of tracks for the decorative layer. Furthermore, an increase in the predetermined contraction distance L makes the slope of the decorative structure S gentle. In this way, if the touch sensing structure (not shown in FIG. 1 ) is directly formed on the decorative panel 100 , the touch sensing structure can well climb the first decorative layer from the light transmitting area AA of the first substrate 110 . 120. The second decorative layer 130 and the first light shielding layer 140 (ie, the decorative structure S) are less prone to disconnection. In addition, when the slope of the decorative structure S is relatively flat, if the touch sensing structure is attached to the decorative panel 100 through the adhesive layer (not shown in FIG. 1 ), the slope between the adhesive layer and the decorative structure S is less likely to remain. bubble.

Furthermore, since the second decorative layer can be formed on the first decorative layer with a larger predetermined contraction distance, the second side of the second decorative layer can be made more gradual, and the problem of the above-mentioned disconnection and residual bubbles is obtained more. Further improvement. This will be explained below with reference to Fig. 3A. 3A is a cross-sectional view of a decorative panel in accordance with an embodiment of the present invention. Referring to FIG. 3A, the decorative panel 100A of FIG. 3A is similar to the decorative panel 100 of FIG. 1, and thus the same elements are denoted by the same reference numerals. The second decorative layer 130 has a second bottom surface 130b facing the first substrate 110, a second top surface 130c opposite to the second bottom surface 130b, and a second side surface 130d connecting the second bottom surface 130b and the second top surface 130c. The second side 130d is the edge of the second decorative opening 130a. Referring to FIGS. 1 and 3A , the difference between the decorative panel 100A and the decorative panel 100 is that the second side 130 d of the second decorative layer 130 of the decorative panel 100A is gentler than the second side 130 d of the second decorative layer 130 of the decorative panel 100 . In other words, the orthographic projection length L2 of the second side surface 130d of the decorative panel 100A on the first substrate 110 is longer than the orthographic projection length L1 of the second side surface 130d of the decorative panel 100 on the first substrate 110. For example, decoration The second side 130d of the panel 100A is inclined with respect to the first substrate 110. When the second side 130d of the second decorative layer 130 of FIG. 3A is more gentle than the second side 130d of the second decorative layer 130 of FIG. 1, the second angle of the second decorative layer 130 of FIG. 3A is preferably also made. The β is smaller than the second angle β of the second decorative layer 130 of FIG. 1, the former being, for example, about 3 to 7 degrees, and the latter being, for example, about 7 to 15 degrees. The slope of the decorative structure S of FIG. 3A is more gentle than the slope of the decorative structure S of FIG. 1 , and the above-mentioned disconnection and residual air bubbles are less likely to occur on the decorative panel 100A, and a specific example of the occurrence of disconnection is, for example, a line width of 1 ~15 micron metal thin wires or/and metal meshes composed of thin metal wires. 3B is a top plan view of the decorative panel of FIG. 3A. Referring to FIG. 3B, the touch panel structure 200 can be directly formed on the decorative panel 100A of FIG. 3A. If the touch component structure 200 has the metal thin line E, the partial line width W1 of the metal thin line E located in the transparent area AA is preferably smaller than 6 microns. It is considered that the thin metal wire E formed in the peripheral region BB is shielded by the decorative structure S and is easily broken. Therefore, the line width W2 of the metal thin wire E located in the peripheral portion BB portion E2 is preferably larger than the thin metal wire in the light transmitting region AA (ie, For example greater than 6 microns). More specifically, the line width W of the metal thin line E of the touch element structure 200 at the boundary between the penetration area AA and the peripheral area BB may gradually increase from the penetration area AA to the peripheral area BB. Of course, the above metal thin wires E or/and the metal mesh may have different line widths W1 and W2 in the light transmitting area AA and the peripheral area BB, and are also applicable to other embodiments of the present invention, and the line width W is gradually increased. The design is not limited to metal thin wires E, but also to other transparent conductive materials such as metal oxides such as indium tin oxide (ITO).

Please refer to 4, the decorative panel 100B of FIG. 4 is similar to the decorative panel 100 of FIG. 1, and thus the same elements are denoted by the same reference numerals. In the embodiment of FIG. 4, the area of the first decorative opening 120a is smaller than the area of the second decorative opening 130a. In other words, the first decorative layer 120 may protrude toward the light transmitting area AA to the outside of the second decorative layer 130. The area of the second decorative opening 130a is smaller than the area of the third decorative opening 140a. In other words, the second decorative layer 130 may protrude toward the light transmitting area AA to the outside of the first light shielding layer 140. Referring to FIGS. 1 and 4 , the difference between the decorative panel 100 of FIG. 1 and the decorative panel 100B of FIG. 4 is that the decorative panel 100B of FIG. 4 further includes a gentle layer 192 . The gentle layer 192 covers at least a portion of the second decorative layer 130 protruding toward the light-transmitting area AA to the outside of the first light-shielding layer 140 and a portion of the first decorative layer 120 protruding toward the light-transmitting area AA to the outside of the second decorative layer 130. Part. The gentle layer 192 fills the unevenness of the decorative structure S, so that the decorative panel 100B is less prone to the above-mentioned disconnection and bubble remaining problems than the decorative panel 100. In addition, the gentle layer 192 may also cover the first decorative layer 120 and be in contact with the first substrate 110 to smooth the first decorative layer 120. In this way, after the gentle layer 192 is added, the maximum inclination angle of the decorative structure S can be changed from the first angle α of the first decorative layer 120 to the inclination angle γ of the smaller gentle layer 192 to further improve the disconnection. And the problem of residual bubbles. In addition, in other embodiments, the gentle layer 192 preferably further extends inwardly to the light-transmitting area AA, and completely covers the light-transmitting area AA, and optionally extends outward to cover the entire area. Decorative structure S.
