[0031] like Figure 1 and Figure 2As shown in the figure, this application embodiment proposes an integrated black thin film touch screen, including: a substrate 110, the material of which the substrate 110 is made of black PET material; a touch circuit layer 120, the touch circuit layer 120 is disposed on the substrate 110; a conductor layer 130, the conductor layer is disposed on the substrate 110, one end of the conductor layer 130 is connected to the touch circuit layer 120, and the other end is led out to the substrate 110; and a cover plate 140, the cover plate 140 is connected to the substrate 110, and covers the touch circuit layer 120 and the conductor layer.
[0032] The integrated black film touchscreen provided in this embodiment includes a substrate 110, a touch circuit layer 120, a conductive layer 130, and a cover plate 140. The substrate 110 is made of black PET material. Based on this, in the manufacturing process of the integrated black film touchscreen provided in this embodiment, the black PET material can be mechanically cut according to the size requirements of the integrated black film touchscreen. Then, the black PET material undergoes an aging treatment to obtain the substrate 110. Printing is then performed on the substrate 110, followed by curing, to prepare the conductive layer 130 on the substrate 110. Then, the touch circuit layer 120 is set on it using a conventional dummy process. Finally, the cover plate 140 is set to complete the manufacturing of the integrated black film touchscreen. This integrated black film touchscreen ensures both a seamless black appearance and effective touch control. Utilizing the black PET material substrate 110 eliminates the need for staining the glass substrate, improving processing efficiency and reducing costs.
[0033] It is understood that the specific steps for fabricating the touch circuit layer 120 may include first forming a metal layer on the substrate 110, and then etching the metal layer to form the touch circuit layer 120.
[0034] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the integrated black film touch screen further includes a rigid substrate 150, with a substrate 110 disposed on the rigid substrate 150.
