The substrate 201 in the cover plate 20 can be a rigid substrate including a transparent material, a flexible substrate, or a combination thereof. The substrate 201 can include a single-layer or multi-layer structure. In some embodiments, the substrate 201 can include glass, quartz, sapphire, ceramics, polyimide (PI), polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), polycaprolactone (PCL), other suitable materials, or any combination thereof, but the present invention is not limited thereto.

In some embodiments, the transmittance range of the cover plate 20 corresponding to the peripheral area NA of the display panel 10 is also 20% - 92%, but the present invention is not limited thereto.

[0054] The anti-reflection layer 205 can adjust the reflectivity of the cover plate 20. The anti-reflection layer 205 can include a single-layer structure or a multi-layer structure.

Except that the high refractive index layer 2053 in the antireflection layer 205 is replaced by the light absorbing layer 2055, Figure 2 the structure of the antireflection layer 205 shown is substantially the same as that of the antireflection layer 205 shown above Figure 1 shown, so it will not be described in detail herein. In some embodiments, the ink layer 203 may be omitted.

[0057] In some other embodiments, the antireflection layer 205 may include a low refractive index layer 2051, a high refractive index layer 2053, and a light absorbing layer 2055.

Except that the antireflection layer 205 includes the light absorbing layer 2055 between the low refractive index layer 2051 and the substrate 201, Figure 3 the structure of the antireflection layer 205 shown is substantially the same as that of the antireflection layer 205 shown above Figure 1 shown, so it will not be described in detail herein. In some embodiments, the ink layer 203 may be omitted.

The cover plate 20 may include the above-mentioned substrate 201, light shielding structure 202, and antireflection layer 205.

[0060] Figure 4 is a schematic cross-sectional view of an electronic device according to an embodiment of the present invention. Figure 4The electronic device shown includes a display panel 10 and a cover plate 20 disposed relative to the display panel 10. The display panel 10 may have a display area AA and a peripheral area NA adjacent to the display area AA. The cover plate 20 may include a substrate 201, an ink layer 203 disposed on a surface 201S1 of the substrate 201 and corresponding to the display area AA and the peripheral area NA of the display panel 10, a light-shielding structure 202 disposed on the surface 201S1 of the substrate 201 and including a first portion 2021 corresponding to the display area AA of the display panel 10, and an anti-reflection layer 205 disposed on another surface 201S2 of the substrate 201 and corresponding to the display area AA and the peripheral area NA of the display panel 10, wherein the transmittance range of the cover plate 20 corresponding to the display area AA of the display panel 10 is 20% to 92%, but the present invention is not limited thereto. By disposing the light-shielding structure 202 on the surface 201S1 of the substrate 201, even if the ink layer 203 is omitted, the transmittance range of the cover plate 20 corresponding to the display area AA of the display panel 10 is still 20% to 92%. Therefore, in some embodiments, the ink layer 203 may be omitted. In addition to further including the light-shielding structure 202, Figure 4 the structure of the electronic device shown is Figure 1 substantially the same as the structure of the electronic device shown, so it will not be described herein again.

[0062] Refer to Figure 4, the light-shielding structure 202 may include a first portion 2021 corresponding to the display area AA of the display panel 10 and a second portion 2023 corresponding to the peripheral area NA of the display panel 10, but the present invention is not limited thereto. In some embodiments, the light-shielding structure 202 may not include the second portion 2023 corresponding to the peripheral area NA of the display panel 10. By disposing the light-shielding structure 202 on the surface 201S1 of the substrate 201, the transmittance range of the cover plate 20 corresponding to the display area AA of the display panel 10 may be 20% to 92%, but the present invention is not limited thereto. In some embodiments, the transmittance range of the cover plate 20 corresponding to the display area AA of the display panel 10 is 20% to 50% or 50% to 70% or 70% to 92%. In some embodiments, the transmittance range of the cover plate 20 corresponding to the peripheral area NA of the display panel 10 is also 20% to 92%, but the present invention is not limited thereto. The transmittance of the cover plate 20 may be adjusted by disposing light-shielding structures 202 including different structures. In some embodiments, the transmittance of the cover plate 20 corresponding to the display area AA of the display panel 10 may be made the same as the transmittance of the cover plate 20 corresponding to the peripheral area NA of the display panel 10 by making the first portion 2021 and the second portion 2023 of the light-shielding structure 202 have the same structure, but the present invention is not limited thereto. In some embodiments, the transmittance of the cover plate 20 corresponding to the display area AA of the display panel 10 may be made greater than or less than the transmittance of the cover plate 20 corresponding to the peripheral area NA of the display panel 10 by making the first portion 2021 and the second portion 2023 of the light-shielding structure 202 have different structures.

The light-shielding structure 202 may be formed using a laser engraving manufacturing process, an inkjet printing manufacturing process, a screen printing manufacturing process, or any other suitable manufacturing process.

[0064] Figure 5 is a top view schematic diagram of the light-shielding structure 202 being a continuous layer including the first portion 2021 and the second portion 2023 according to some embodiments of the present invention. In some embodiments, Figure 5The light-shielding structure 202 shown is formed using a laser engraving manufacturing process. As Figure 5 shown, the first part 2021 of the light-shielding structure 202 may include at least one first opening H1, and the second part 2023 may include at least one second opening H2. The surface 201S1 of the substrate 201 may be exposed to the outside through the first opening H1 and the second opening H2, as Figure 4 shown. In some embodiments where the cover plate 20 includes both the ink layer 203 and the light-shielding structure 202, the ink layer 203 may fill the first opening H1 and the second opening H2 of the light-shielding structure 202 and contact the surface 201S1 of the substrate 201, as Figure 4 shown.

In the case where the second part 2023 of the light-shielding structure 202 includes two or more second openings H2, the second widths W2 of these second openings H2 can be the same as or different from each other. In some embodiments, each first opening H1 can have the same first width W1, each second opening H2 can have the same second width W2, and the first width W1 is the same as the second width W2, as shown in Figure 5 (a) of, but the present invention is not limited thereto. In some embodiments, the first width W1 of the first opening H1 can be greater than the second width W2 of the second opening. Among the multiple first openings H1, the first opening H1 closer to the second part 2023 has a smaller first width W1, and among the multiple second openings H2, the second opening H2 closer to the first part 2021 has a larger second width W2, as shown in Figure 5 (b) of, but the present invention is not limited thereto. In some embodiments, the first width W1 of the first opening H1 can be less than the second width W2 of the second opening H2. Among the multiple first openings H1, the first opening H1 closer to the second part 2023 has a larger first width W1, and among the multiple second openings H2, the second opening H2 closer to the first part 2021 has a smaller second width W2, as shown in Figure 5 (c) of, but the present invention is not limited thereto.

[0068] In an embodiment where the first opening H1 and the second opening H2 include holes, the term "first pitch P1" refers to the distance between the center point of the first opening H1 and the center point of another adjacent first opening H1. The term "second pitch P2" refers to the distance between the center point of the second opening H2 and the center point of another adjacent second opening H2. The term "third pitch P3" refers to the distance between the center point of the first opening H1 and the center point of the adjacent second opening H2. The term "adjacent" here means that there are no other openings therebetween. In an embodiment where the first opening H1 and the second opening H2 include circular holes, the center points of the first opening H1 and the first opening H2 refer to their centers, as shown in Figure 5As shown in (a) to (c) thereof. In an embodiment where the first opening H1 and the second opening H2 are holes, the first pitch P1 may be between 250 and 3000 μm, the second pitch P2 may be between 250 and 3000 μm, and the third pitch P3 may be between 250 and 3000 μm. In the case where there are two or more first pitches P1, these first pitches P1 may be the same as or different from each other. In the case where there are two or more second pitches P2, these second pitches P2 may be the same as or different from each other. In the case where there are two or more third pitches P3, these third pitches P3 may be the same as or different from each other.
