The present invention will be described in detail with reference to the preferred embodiments of the invention,

As shown in FIGS. 1 and 2, the cover sheet 101 of the first embodiment of the present invention has a light transmitting region R1 and a peripheral region R2 located on at least one side of the light transmitting region R1. In the present embodiment, the surrounding area R2 preferably surrounds the light transmitting area R1, but is not limited thereto. The cover plate 101 includes a substrate 110, a decorative structure 120, a decorative effect layer 140 and a light transmitting structure 130. The substrate 110 may include a glass substrate, a plastic substrate, a sapphire substrate, or a transparent ceramic substrate. When the substrate 110 is a plastic substrate, it may be a single-layer substrate or a substrate made up of two or more layers of different materials, wherein the material may be selected from polyethylene terephthalate (PET), polypropylene. (polypropylene, PP), polyethylene (PE), polycarbonate (PC), polymethyl methacrylate (PMMA), polyimide (PI), polycycloolefin polymerization Cyclo olefin polymer (COP), for example, a cover plate in which PMMA and PC double-layer materials are stacked. When the substrate is a glass substrate, the glass substrate may be a chemically or physically strengthened tempered glass, thereby having high mechanical strength to protect the touch element and the matched display, and the thickness of the substrate may be between 0.25 mm and Between 2 mm. The substrate of the display may be a color filter substrate, an active array substrate or a package cover of an organic light emitting display, but is not limited thereto. The substrate 110 has a first surface 110A and a second surface 110B, and the second surface 110B is opposite to the first surface 110A. The decorative structure 120 is disposed on the first surface 110A of the substrate 110 and located in the surrounding area R2 for forming a decorative effect on one side of the second surface 110B of the substrate 110. The decorative structure 120 may be formed of a single layer or a multi-layered decorative layer such as black ink, black photoresist, color ink, color photoresist or other material having a color or material effect. The decorative structure 120 includes at least one hollow pattern 120M, and the hollow pattern 120M can be defined to remove a portion of the decorative structure 120 for exposure A corresponding hollow pattern of the substrate 110. It should be noted that the hollow pattern 120M of the present invention can be used to form an icon (such as a trademark logo), a text (such as a product model), or a functional button (such as a return button or a Home button) on the cover panel 101, but not Limited. The decorative effect layer 140 is disposed on the decorative structure 120 and covers the hollow pattern 120M. The decorative effect layer 140 may include a color effect layer (such as ink) or a material effect layer (such as mirror silver) or other material suitable for forming an appearance effect. The light-transmitting structure 130 is at least partially disposed in the hollow pattern 120M, and the light-transmitting structure 130 is at least partially disposed between the decorative effect layer 140 and the substrate 110 for the decorative effect layer 140 located in the hollow pattern 120M on the substrate 110. A three-dimensional pattern effect is presented on the second side 110B.

It is further explained that the decorative structure 120 of the embodiment has at least two sidewalls 120W in a cross-sectional section, the hollow pattern 120M is located between the two sidewalls 120W, and the hollow pattern 120M has a central region 120C and an edge region 120E. The edge region 120E surrounds the central region 120C. In other words, the edge region 120E can be considered as a contour region of the hollow pattern 120M. The light transmissive structure 130 of the present embodiment is extended from the decorative structure 120 to cover and fill the hollow pattern 120M. Due to the thickness of the decorative structure 120, the first thickness D1 of the light transmitting structure 130 in the central region 120C of the hollow pattern 120M is made smaller than the second thickness D2 of the light transmitting structure 130 in the edge region 120E of the hollow pattern 120M. The difference in thickness between the central region 120C and the edge region 120E in the hollow pattern 120M of the light transmissive structure 130 can produce a lens-like effect on the decorative effect layer 140, thereby allowing the user to be on the second side 110B of the substrate 110. The visual perception of the three-dimensional pattern is obtained when one side views the hollow pattern 120M and the corresponding decorative effect layer 140. At the same time, the light-transmitting structure 130 in the hollow pattern 120M is at least partially curved toward one side of the decorative effect layer 140 to increase the smoothness of the three-dimensional pattern in visual perception.

In this embodiment, each side wall 120W has an angle A with the substrate 110, and the angle A is preferably between 5 degrees and 90 degrees to control the second thickness of the light transmitting structure 130 at the edge region 120E. The distribution of D2, but not limited to this. In addition, the light transmissive structure 130 may be formed of a single layer or a plurality of stacked light transmissive materials, which may include a transparent insulating material or a transparent conductive material. For example, the light transmitting structure 130 of the embodiment may be formed by a first light transmissive layer 131. The first light-transmissive layer 131 can be a transparent insulating material generally used in a touch device, thereby eliminating the need for an additional process to form the desired light-transmitting structure 130, and thus has the advantage of not causing an increase in manufacturing cost. In other words, the structural design of the cover plate 101 of the present embodiment can achieve the purpose of the stereoscopic effect of the hollow pattern 120M under the existing manufacturing process.

As shown in FIG. 3, the decorative effect layer 140 of the present embodiment may be a fixed shape (for example, a rectangular shape) covering the hollow pattern 120M. In addition, as shown in FIG. 4, the pattern of the decorative effect layer 140 may also be adjusted according to the pattern of the hollow pattern 120M, so that the decorative effect layer 140 has a pattern similar to the hollow pattern 120M, thereby controlling the cover layer caused by the decorative effect layer 140. The terrain on the board is affected by fluctuations, but not limited to this.

In other words, the light-transmitting structure 130 may be disposed only in the edge region 120E of the hollow pattern 120M without covering the central region 120C of the hollow pattern 120M. Since the light-transmitting structure 130 is not disposed at least partially in the central region 120C, it is located in the edge region 120E. The light-transmitting structure 130 can also produce a lens-like effect on the decorative effect layer 140, thereby enabling the user to obtain the three-dimensional pattern when viewing the hollow pattern 120M and the corresponding decorative effect layer 140 on one side of the second surface 110B of the substrate 110. visual feeling.

Another layer of transparent insulating material allows for the formation of the desired light transmissive structure 130 without the need for additional processing. In addition, by the arrangement of the second light transmissive layer 132, a gap between the first thickness D1 of the light transmissive structure 130 in the central region 120C and the second thickness D2 of the light transmissive structure 130 in the edge region 120E may be caused to form a gap.

Thereby, the gap between the first thickness D1 of the light transmitting structure 130 in the central region 120C and the second thickness D2 of the light transmitting structure 130 in the edge region 120E is enlarged, thereby enhancing the lens effect caused by the light transmitting structure 130.
