實施例二
On this basis, since each
本實施的觸控模組30如圖7所示,與實施例一的區別在於觸控層2的結構不同。以下主要對區別部分進行說明,其他部分與實施例一基本一致。The
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
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
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
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
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
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
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
