The material of the second insulating layer 244b can be selected according to actual needs, and the thickness of the second insulating layer 244b can also be designed according to actual needs.
第二絕緣層244b的材料與第一絕緣層244a的 材料可為相同或不相同。第二絕緣層244b的厚度與第一絕緣層244a的厚度可為相同或不相同。 The material of the second insulating layer 244b and the first insulating layer 244a The materials may be the same or different. The thickness of the second insulating layer 244b may be the same as or different from the thickness of the first insulating layer 244a.
在一些實施例中，觸控顯示裝置200更包含黏合層250a及250b。黏合層250a設置於觸控接收電極層Rx1與覆蓋玻璃210之間。黏合層250b亦設置於壓力接收電極層Rx2與顯示陣列220之間。黏合層250a及250b的材料包含光學膠或其他具有黏合功能的材料。黏合層250a及250b的材料可依實際需求進行挑選，而黏合層250a及250b的厚度亦可依實際需求進行設計。舉例來說，黏合層250a及250b的厚度可約為0.025毫米(mm)至0.05毫米(mm)。 In some embodiments, the touch display device 200 further includes adhesive layers 250a and 250b. The adhesive layer 250a is disposed between the touch receiving electrode layer Rx1 and the cover glass 210. The adhesive layer 250b is also disposed between the pressure receiving electrode layer Rx2 and the display array 220. The materials of the adhesive layers 250a and 250b comprise optical glue or other materials having a bonding function. The materials of the adhesive layers 250a and 250b can be selected according to actual needs, and the thickness of the adhesive layers 250a and 250b can also be designed according to actual needs. For example, the thickness of the adhesive layers 250a and 250b can be from about 0.025 millimeters (mm) to 0.05 millimeters (mm).
黏合層250a的材料與黏合層250b的材料可為相同或不相同。黏合層250a的厚度與黏合層250b的厚度可為相同或不相同。 The material of the adhesive layer 250a and the material of the adhesive layer 250b may be the same or different. The thickness of the adhesive layer 250a and the thickness of the adhesive layer 250b may be the same or different.
另外，在一些實施例中，觸控顯示裝置200更包含框架260。熟知本領域的人員皆熟知框架260的相關內容，因此不再贅述。 In addition, in some embodiments, the touch display device 200 further includes a frame 260. The relevant content of the framework 260 is well known to those skilled in the art, and therefore will not be described again.
綜上所述，本揭露中的觸控顯示裝置透過特殊配置，形成具有壓力感測功能且具有新型架構的觸控顯示裝置。另外，由於本揭露中的觸控顯示裝置具有壓力感測功能，因此使用者可利用絕緣的物件進行觸控操作。 In summary, the touch display device of the present disclosure has a special configuration to form a touch display device having a pressure sensing function and having a novel structure. In addition, since the touch display device of the present disclosure has a pressure sensing function, the user can perform an touch operation using the insulated object.
雖然本揭露已以實施方式揭露如上，然其並非用以限定本揭露，任何本領域具通常知識者，在不脫離本揭露之精神和範圍內，當可作各種之更動與潤飾，因此本揭露之保護範圍當視後附之申請專利範圍所界定者為準。 The present disclosure has been disclosed in the above embodiments, and is not intended to limit the disclosure. Any one of ordinary skill in the art can make various changes and refinements without departing from the spirit and scope of the disclosure. The scope of protection is subject to the definition of the scope of the patent application.
