Here, the protective substrate 121 is, for example but not limited to, a cover glass (C/G) to protect the blue light-resistant layer 122, the touch electrode layer 123, and the display panel 11 from moisture or foreign matter.
抗藍光層122設置於保護基板121與顯示面板11之間。本實施例之抗藍光層122是設置於保護基板121面對顯示面板11的第一表面1211上。其中,抗藍光層122是由複數對的第一材料層1221與第二材料層1222疊設而成。換言之,一層第一材料層1221堆疊一層第二材料層1222可稱為1對。如圖1B所示,抗藍光層122可由N對的第一材料層1221與第二材料層1222堆疊而成。其中,為了有效攔截短波藍光及UV光,N的值最少為12,也就是總層數為24層。另一方面,在實際設計上,因為抗藍光層122的組成層數到達一定的數量之後,其光學效果的改善有限,並且本實施例再依據應用於觸控顯示裝置1時的厚度考量,N的值最多為30,也就是60層。另外,本實施例之抗藍光層122由下而上依序為第一材料層1221、第二材料層1222、第一材料層1221、第二材料層1222、…、第一材料層1221、第二材料層1222。 The anti-blue light layer 122 is disposed between the protective substrate 121 and the display panel 11. The blue light-resistant layer 122 of the present embodiment is disposed on the first surface 1211 of the protective substrate 121 facing the display panel 11. The anti-blue light layer 122 is formed by stacking a plurality of pairs of first material layers 1221 and second material layers 1222. In other words, stacking a layer of first material layer 1221 with a layer of second material layer 1222 may be referred to as a pair.

Among them, in order to effectively intercept short-wave blue light and UV light, the value of N is at least 12, that is, the total number of layers is 24 layers. On the other hand, in practical design, since the number of constituent layers of the anti-blue light layer 122 reaches a certain amount, the improvement of the optical effect is limited, and the thickness variation of the embodiment is applied according to the thickness of the touch display device 1, N The value is up to 30, which is 60 layers. In addition, the blue light-resistant layer 122 of the present embodiment is sequentially composed of a first material layer 1221, a second material layer 1222, a first material layer 1221, a second material layer 1222, ..., a first material layer 1221, from bottom to top.

It belongs to the high refractive index layer, and the second material layer 1222 belongs to the low refractive index layer. In order to further avoid the optical visual effect of the blue light resistant layer 122, the stacked state of the low refractive index layer and the high refractive index layer of FIG. 1C is first. In the sample, the second layer of the second material layer 1222 having a low refractive index may be further added to the upper layer, and thus, the calculation is exemplified by the minimum number of layers of the anti-blue layer 122. The total number of layers in the embodiment of 1C is 25 layers.

另外,請參照圖2所示,其為本創作不同實施態樣的觸控顯示裝置1a的示意圖。 In addition, please refer to FIG. 2 , which is a schematic diagram of the touch display device 1 a according to different implementations.
觸控顯示裝置1a與圖1A的觸控顯示裝置1主要的不同在於,觸控顯示裝置1a的觸控電極層123設置於保護基板121面對顯示面板11的第一表面1211上,而抗藍光層122則設置於顯示面板11面對保護基板121的上表面111上,更具體來講,觸控電極層123是通過光微影製程直接形成在保護基板121的第一表面1211,而抗藍光層122是通過蒸鍍或濺鍍製程直接形成於顯示面板11的上表面111。此外,觸控電極層123與抗藍光層122之間更設置有粘著層124,讓具有觸控電極層123的保護基板121進一步通過粘著層124貼合於具有抗藍光層122的顯示面板11。在另一實施例中,在觸控電極層123形成於保護基板121的第一表面1211之後,在製程上不致損壞觸控電極層123的情況下,抗藍光層122可通過蒸鍍或濺鍍製程形成於觸控電極層123面對顯示面板11的表面上,並且抗藍光層122與顯示面板11之間更設置粘著層124,讓具有觸控電極層123及抗藍光層122的保護基板121進一步通過粘著層124而貼合於顯示面板11的上表面111。由此結構來看,抗藍光層122是通過粘著層124設置於顯示面板11的上表面111。 The main difference between the touch display device 1 and the touch display device 1 of FIG. 1A is that the touch electrode layer 123 of the touch display device 1a is disposed on the first surface 1211 of the protective substrate 121 facing the display panel 11, and is resistant to blue light. The layer 122 is disposed on the upper surface 111 of the display substrate 11 facing the protective substrate 121. More specifically, the touch electrode layer 123 is directly formed on the first surface 1211 of the protective substrate 121 by a photolithography process, and is resistant to blue light. The layer 122 is directly formed on the upper surface 111 of the display panel 11 by an evaporation or sputtering process. In addition, an adhesive layer 124 is further disposed between the touch electrode layer 123 and the blue light-resistant layer 122, and the protective substrate 121 having the touch electrode layer 123 is further adhered to the display panel having the blue light-resistant layer 122 through the adhesive layer 124. 11. In another embodiment, after the touch electrode layer 123 is formed on the first surface 1211 of the protection substrate 121, and the touch electrode layer 123 is not damaged in the process, the blue light-resistant layer 122 can be evaporated or sputtered. The process is formed on the surface of the touch electrode layer 123 facing the display panel 11 , and an adhesive layer 124 is further disposed between the anti-blue layer 122 and the display panel 11 , and the protective substrate having the touch electrode layer 123 and the anti-blue layer 122 is disposed. The 121 is further bonded to the upper surface 111 of the display panel 11 by the adhesive layer 124. The anti-blue light layer 122 is disposed on the upper surface 111 of the display panel 11 through the adhesive layer 124 in view of the structure.
此外,觸控顯示裝置1a的其他技術特徵可參照觸控顯示裝置1,於此亦不再贅述。 For other technical features of the touch display device 1a, reference may be made to the touch display device 1, and details are not described herein.
再補充的是,觸控電極層123除了如圖1A與圖2所示的單層導電層的觸控電極結構外,也可設計為雙層導電層的觸控電極結構,並且搭配多層基板的觸控結構,如雙玻璃(Glass-Glass,GG)、雙薄膜(Glass-Film-Film,GFF)等,讓抗藍光層122可依據觸控結構的不同以及製程的便利性而設置在保護基板121與顯示面板11之間的不同疊層位置,本創作亦不限制。 In addition, the touch electrode layer 123 can be designed as a touch electrode structure of a double-layer conductive layer in addition to the touch electrode structure of the single-layer conductive layer as shown in FIG. 1A and FIG. 2, and is matched with a multilayer substrate. The touch structure, such as Glass-Glass (GG), Double-Film-Film (GFF), etc., allows the anti-blue layer 122 to be disposed on the protective substrate according to the difference of the touch structure and the convenience of the process. The present invention is also not limited to the different lamination positions between the 121 and the display panel 11.
