Decorative panels and touch devices

technical field

The utility model relates to a decorative element and an electronic device, in particular to a decorative panel and a touch device.

Background technique

In recent years, with the development of the technology industry, handheld electronic devices such as smartphones or tablet computers have been widely used in daily life. The use of these hand-held electronic devices is becoming more and more common, and is developing in the direction of convenience, multi-function and aesthetic design. When consumers purchase these hand-held electronic devices, the aesthetics of the appearance design has gradually become an important purchasing factor besides the software and hardware functions.

Taking smart phones among handheld electronic devices as an example, the appearance of traditional black and white borders can no longer meet the needs of consumers. Therefore, how to make the frame of the smart phone have a specified color, so as to enhance the product value, has become one of the important topics that the research and development personnel pay attention to at present. In the conventional technology, researchers use printing to form multiple decorative layers on the substrate, so that the frame of the smartphone has a specified color. However, during the printing process, the decorative layer is easy to flow before it is cured, which leads to the problem of uneven edges of the decorative layer, which in turn affects the aesthetic appearance of the smartphone.

Detailed ways

Fig. 1 is a schematic cross-sectional view of a decorative panel according to an embodiment of the present invention. Referring to FIG. 1 , the decoration panel 100 includes a first substrate 110 , a first decoration layer 120 , a second decoration layer 130 and a light shielding layer 140 . The first substrate 110 has a transparent area AA and a peripheral area BB outside the transparent area AA. Here, the peripheral area BB does not limit whether it is transparent or not. In this embodiment, the peripheral area BB is opaque after the subsequent decoration structures such as the first and second decorative layers 120, 130 are arranged. In detail, the first A decoration layer 120 is disposed on the peripheral area BB of the first substrate 110 . The second decoration layer 130 is disposed on the peripheral area BB of the first substrate 110 . The first decoration layer 120 is located between the second decoration layer 130 and the first substrate 110 . The light shielding layer 140 is disposed on the peripheral area BB of the first substrate 110 . The second decoration layer 130 is located between the light shielding layer 140 and the first decoration layer 120 . The optical density (OD) of the light-shielding layer 140 is greater than the optical density of the first decoration layer 120 and the optical density of the second decoration layer 130 . The first decoration layer 120 , the second decoration layer 130 and the light-shielding layer 140 respectively have a first decoration opening 120 a , a second decoration opening 130 a and a third decoration opening 140 a that expose the transparent area AA and overlap each other. The first decoration opening 120a, the second decoration opening 130a and the third decoration opening 140a are used to expose the structure of the touch element.

The orthographic projection of the third decoration opening 140 a on the first substrate 110 completely covers the orthographic projection of the first decoration opening 120 a on the first substrate 110 and the orthographic projection of the second decoration opening 130 a on the first substrate 110 . The orthographic projection of the second decoration opening 130 a on the first substrate 110 completely covers the orthographic projection of the first decoration opening 120 a on the first substrate 110 . The first decoration layer 120 and the second decoration layer 130 are stacked in the direction d. The thickness T2 of the second decoration layer 130 in the direction d is greater than the thickness T1 of the first decoration layer 120 in the direction d. It is also mentioned that the peripheral area BB is not limited to surround the light-transmitting area AA, but only needs to be disposed on at least one side of the light-transmitting area AA. In other words, the first and second decoration layers 120, 130 and the light-shielding layer 140 can only be arranged on one side of the light-transmitting area AA, and will not present the symmetrical configuration as shown in FIG. It doesn't have to be closed, but can be open.

It is worth mentioning that, in the manufacturing process of the decorative panel 100, the thin first decorative layer 120 is applied on the first substrate 110 first. Before the first decoration layer 120 is cured, the first decoration layer 120 is not easy to flow excessively and cause the problem of uneven edges of the first decoration opening 120 a. After the first decoration layer 120 is finished, the inner boundary of the decoration structure S composed of at least the first decoration layer 120 , the second decoration layer 130 and the light-shielding layer 140 (namely the first decoration opening 120 a ) is defined. Another thing to mention is that the thinner first decoration layer 120 can also prevent the position of the inner boundary of the decoration structure S from shifting, and can define the originally set light-transmitting area AA. Display assembly work. Next, the second decoration layer 130 can be applied on the first decoration layer 120 and retracted by a predetermined distance, so as to increase the optical density of the overall decoration structure S through the thicker second decoration layer 130 . In this way, the number of printing passes of the subsequent decorative layer can be reduced, and even the subsequent decorative layer can be omitted. In this way, the effect of making the decorative structure S have both edge flatness and shielding properties can be achieved. It is also mentioned that, in other embodiments, a barrier layer (not shown) may be provided between the light-shielding layer 140 and the second decoration layer 130 to avoid color mixing between the light-shielding layer 140 and the second decoration layer 130, especially when When the second decoration layer 130 and the light shielding layer 140 are of different materials and colors. The barrier layer is, for example, an inorganic or organic film layer. The inorganic film layer is, for example, silicon oxide, nitrogen oxide, or a composite film layer of silicon oxide and nitrogen oxide, and this inorganic film layer can be selectively extended to the light-transmitting area AA to simultaneously Used as an optical matching layer. The organic film layer is, for example, a photosensitive resin.

There is a second height difference ΔH2 between the second central portion 132 and the second edge protruding portion 134 in the direction d. The second height difference ΔH2 is greater than the first height difference ΔH1.

FIG. 3 is a partially enlarged schematic view of the decorative panel in FIG. 1 . In particular, FIG. 3 corresponds to region R of FIG. 1 . Referring to FIG. 3 , in this embodiment, the taper angle of the second decoration layer 130 is larger than the taper angle of the first decoration layer 120 . Specifically, the first decoration layer 120 has a first bottom surface 120b facing the first substrate 110, a first top surface 120c opposite to the first bottom surface 120b, and a first side surface 120d connecting the first bottom surface 120b and the first top surface 120c. . The first bottom surface 120b intersects the first side surface 120d at a first junction I1. The first junction I1 is an edge of the first decoration opening 120a. The first reference plane P1 is tangent to the first side surface 120d and passes through the first boundary I1. The second reference plane P2 is tangent to the first bottom surface 120b and passes through the first boundary I1. The first reference plane P1 and the second reference plane P2 form a first angle α within the material of the first decoration layer 120 . The second decoration 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 bottom surface 130b intersects with the second side surface 130d at the second junction I2. The second junction I2 is an edge of the second decoration opening 130a. The third reference plane P3 is tangent to the second side surface 130d and passes through the second boundary I2. The fourth reference plane P4 is tangent to the second bottom surface 130b and passes through the second boundary I2. The third reference plane P3 and the fourth reference plane P4 form a second angle β within the material of the second decoration layer 130 . In this embodiment, the second angle β may be greater than the first angle α, but the utility model is not limited thereto. In other embodiments, the first angle α and the second angle β may also have other appropriate relative relationships, Examples will be given below in subsequent examples.

Please refer to FIG. 1 again. In this embodiment, if the overall optical density of the first and second decorative layers 120, 130 is insufficient, the decorative panel 100 may optionally include a third decorative layer 150 to increase the optical density of the decorative structure S. . The second decoration layer 130 is located between the third decoration layer 150 and the first decoration layer 120 . The third decoration layer 150 has a fourth decoration opening 150 a exposing the light-transmitting area AA and overlapping with the first decoration opening 120 a. The orthographic projection of the fourth decoration opening 150 a on the first substrate 110 completely covers the orthographic projection of the first decoration opening 120 a on the first substrate 110 . In other words, like the second decoration layer 130 , the edge of the third decoration layer 150 close to the light-transmitting area AA does not exceed the edge of the first decoration layer 120 close to the light-transmitting area AA.

If the overall optical density of the first, second, and third decorative layers 120 , 130 , 150 is still insufficient, the decorative panel 100 may optionally include a fourth decorative layer 160 to increase the optical density of the decorative structure S. The third decoration layer 150 is located between the fourth decoration layer 160 and the second decoration layer 130 . The fourth decoration layer 160 has a fifth decoration opening 160a exposing the light transmission area AA.

In other words, the part of the edge of the fourth decoration layer 160 close to the light-transmitting area AA does not exceed the part of the edge of the first decoration layer 120 close to the light-transmitting area AA.

It is worth mentioning that, in addition to the second decoration layer 130 , the thicknesses T3 and T4 of the third and fourth decoration layers 150 and 160 can also be greater than the thickness T1 of the first decoration layer 120 to ensure the concealment of the decoration structure S. However, the thicknesses T3 and T4 of the third and fourth decoration layers 150 and 160 do not need to be greater than the thickness T2 of the second decoration layer 130 , in order to avoid excessive gradient color difference of the decoration structure S. For example, the thicknesses T1, T2, T3, T4 of the first, second, third, and fourth decorative layers 120, 130, 150, and 160 and the thickness T5 of the light-shielding layer 140 can be 5-8 microns (μm), 26 microns, respectively. , 15 microns, 15 microns and 1-5 microns. But the utility model is not limited thereto, and the thicknesses T1, T2, T3, T4 of the first, second, third, and fourth decorative layers 120, 130, 150, and 160 and the thickness T5 of the light-shielding layer 140 can be designed according to actual needs. .

In this embodiment, the first, second, third, and fourth decorative layers 120, 130, 150, and 160 can be light-colored inks (such as white inks), and the light-shielding layer 140 can be dark-colored inks (such as gray or black inks). . However, the present invention is not limited thereto. In other embodiments, the materials and colors of the first, second, third, and fourth decorative layers 120 , 130 , 150 , 160 and the light-shielding layer 140 can also be designed in other appropriate ways. For example, in other embodiments, the material of the first decoration layer 120 can be selected from photoresist. At this time, the inner boundary of the decoration structure S (that is, the first decoration opening 120a) is the first decoration formed by photolithography. The layer 120 is defined, and the lithography process can accurately produce the desired pattern, so that the inner boundary of the decoration structure S can have high edge flatness, and the position of the inner boundary is precise. It is also mentioned that the light-shielding layer 140 can also be made of the same material and color as the first and second decoration layers.

Fig. 4 is a schematic cross-sectional view of a decorative panel according to an embodiment of the present invention. Please refer to FIG. 4 , the decorative panel 100A of FIG. 4 is similar to the decorative panel 100 of FIG. 1 , so the same or corresponding elements are denoted by the same or corresponding reference numerals. The differences between the two are described below, and the similarities between the two will not be repeated. Compared with the decorative panel 100, the decorative panel 100A can use a material with high optical density to make the second decorative layer 130, so that the decorative panel 100A can omit the arrangement of the third and fourth decorative layers 150, 160 in FIG. Sufficient shelter. In the decorative panel 100A, the thicknesses T1 and T2 of the first and second decorative layers 120 and 130 and the thickness T5 of the light-shielding layer 140 can be 5-8 microns, 15-16 microns, and 8-9 microns respectively, but the utility model does not This is the limit.

Please refer to FIG. 5 , the decorative panel 100B of FIG. 5 is similar to the decorative panel 100 of FIG. 1 , so the same or corresponding components are denoted by the same or corresponding reference numerals. The differences between the two are described below, and the similarities between the two will not be repeated. In the decorative panel 100A, the second angle β may be smaller than the first angle α. In detail, if the edge of the first decoration opening 120a defined by the first decoration layer 120 in FIG. For the uneven part of the first decoration layer 120 , the laser removal operation can preferably reuse the laser process for patterning the touch element to form the decoration panel 100B of FIG. 5 . It should be noted that after the first decoration layer 120 is trimmed by laser, the first side 120d' of the first decoration layer 120 will be relatively steep, so that the first angle α is greater than the second angle β. For example, the first side 120d' can be nearly vertical. In other words, the first angle α may be 70-90 degrees. However, the present invention is not limited thereto. The size of the first angle α is related to the laser trimming process parameters and the material selected for the first decoration layer 120. In other embodiments, the first angle α can also be other values larger than the second Angle of angle β.

In the decoration panels 100 , 100A, 100B of FIGS. 1 , 4 and 5 , the area of the first decoration opening 120 a of the first decoration layer 120 may be smaller than the area of the second decoration opening 130 a of the second decoration layer 130 . In other words, the first decoration layer 120 can protrude out of the second decoration layer 130 . However, since the thickness T1 of the first decoration layer 120 is low, the protruding part of the first decoration layer 120 is relatively easy to transmit light, which may cause a gradient of the decoration structure S or an annual ring phenomenon. In this regard, the protruding part of the first decoration layer 120 can be removed by means of laser, so that the color of the decoration structure S can be made more uniform and the gradient problem can be improved.
