本實施例中，觸控層2只包括一種材料層。本實施例中，觸控層2包括金屬，遮光部21及透光部22為相同材料，但遮光部21為連續的結構，透光部22形成網格結構以透光。In this embodiment, the touch layer 2 only includes one material layer. In this embodiment, the touch layer 2 includes metal, the light-shielding portion 21 and the light-transmitting portion 22 are made of the same material, but the light-shielding portion 21 is a continuous structure, and the light-transmitting portion 22 forms a grid structure to transmit light.

本實施例中，觸控層2包括黑化的金屬，使得在蓋板1的第一表面11一側被觀察到時美觀性較好。In this embodiment, the touch layer 2 includes blackened metal, so that the appearance is better when viewed from the first surface 11 side of the cover plate 1 .

本實施例中，觸控層2位於光學膠層6與基板5之間，且觸控層2直接與光學膠層6及基板5接觸。In this embodiment, the touch layer 2 is located between the optical adhesive layer 6 and the substrate 5 , and the touch layer 2 is in direct contact with the optical adhesive layer 6 and the substrate 5 .

本實施例的觸控模組30，可以實現如實施例一中觸控模組10的所有有益效果。在此基礎上，由於本實施例中觸控層2相比實施例一少了一層油墨材料，既減少了製作流程，也減小了觸控模組30的整體厚度。The touch module 30 of this embodiment can achieve all the beneficial effects of the touch module 10 in the first embodiment. On this basis, since the touch layer 2 in this embodiment has one less layer of ink material compared to the first embodiment, the production process is reduced, and the overall thickness of the touch module 30 is also reduced.

請參閱圖8，在本實施例的一變更實施例中，觸控模組40不包括基板5及光學膠層6。也即，該變更實施例中，觸控層2位於蓋板1與保護層7之間，且觸控層2的兩個表面分別直接接觸蓋板1及保護層7。該變更實施例的觸控模組40，由於進一步減少了基板5及光學膠層6，則進一步簡化了製作流程，進一步減小了觸控模組40的厚度。Please refer to FIG. 8 . In a modified embodiment of this embodiment, the touch module 40 does not include the substrate 5 and the optical adhesive layer 6 . That is, in this modified embodiment, the touch layer 2 is located between the cover plate 1 and the protective layer 7 , and the two surfaces of the touch layer 2 are in direct contact with the cover plate 1 and the protective layer 7 respectively. In the touch module 40 of this modified embodiment, since the substrate 5 and the optical adhesive layer 6 are further reduced, the manufacturing process is further simplified and the thickness of the touch module 40 is further reduced.

請參閱圖9，在本實施例的另一變更實施例中，觸控模組50還包括裝飾膜8。裝飾膜8貼附於蓋板1上，且完全覆蓋蓋板1的第一表面11及蓋板1的側面（連接於第一表面11及第二表面12之間的面）。裝飾膜8使得用戶在蓋板1的第一表面11一側可觀察到預設的圖案或顏色，因此該變更實施例中，藉由增加裝飾膜8，使得觸控層2的金屬材料無需被黑化。Please refer to FIG. 9 . In another modified embodiment of this embodiment, the touch module 50 further includes a decorative film 8 . The decorative film 8 is attached to the cover 1 and completely covers the first surface 11 of the cover 1 and the side of the cover 1 (the surface connected between the first surface 11 and the second surface 12 ). The decorative film 8 allows the user to observe a preset pattern or color on the first surface 11 side of the cover 1 . Therefore, in this modified embodiment, by adding the decorative film 8 , the metal material of the touch layer 2 does not need to be removed. Blackening.

上述圖8、圖9所示變更實施例中的觸控模組40及50，可以實現觸控模組30的所有有益效果。The touch modules 40 and 50 in the modified embodiment shown in the above-mentioned FIG. 8 and FIG. 9 can achieve all the beneficial effects of the touch module 30.
