New Description: [New Technology Field] This creation is about a diaphragm structure designed to provide a diaphragm structure that can be applied to a touch panel. [Prior Art] In recent years, the touch-sensitive human-machine interface, such as the touch panel (T〇uch-Pane 1), has been widely used in a wide variety of electronic products, such as: full croquet Positioning system (GPS), personal digital assistant (PDA), ceUular phone, and handheld-handheld computer (Hand-held PC) to replace traditional input devices (such as keyboard and mouse), this design The drastic changes have not only improved the human-machine interface affinity of these electronic devices, but also freed up the traditional input devices, freeing up more space for installing large display panels to facilitate users to browse the data. Conventionally, the structure of the touch panel mainly includes two planar conductive films 11 - to be disposed opposite to each other with a certain gap, as shown in the first figure (A) and the lower φ conductive film 11 is transparently bonded. The layer 12 (optical glue) is disposed on a surface of a transparent plastic substrate 13 having a hard material, and a plurality of bump-like spacers 14 are disposed between the opposite sides of the opposite arrangement, and the conductive film 1 is disposed in the region The gap is disposed inside and the adhesive is applied to the peripheral portion of the ring of the region, so that the two are sealed and bonded together to form a touch sensing component, and a decorative panel 15 is attached over the upper conductive film 11. Then, it is attached to a display screen (not shown) for use. The decorative panel 15 is mainly provided with a transparent substrate 151, and the upper surface of the substrate 151 is provided with a hardened coating 152 to prevent scratches, and the structure of each conductive film 11 is as shown in the first figure. (B), which is provided with a hard coating layer 111, a first transparent substrate 112, a glue layer 113, a second transparent substrate 114, a hard coat layer 115, and a conductive layer 116, respectively, and has an overall thickness of about i88|jm. . However, when the user writes or touches the upper hardened coating 152 for a long time, the force applied to the hardened coating 152 acts directly on the transparent substrate 151 and is directly transmitted to the upper conductive layer. The film η, the spacer 14, the underlying conductive film 11 and the transparent plastic substrate 13 are more likely to cause damage to the structure of the conductive film and the touch panel itself in the writing resistance test. Further, the working mode of the conductive film in the conventional touch panel is further analyzed. When the touch panel input signal is pressed, the external force is applied to the upper hard coating layer. The transparent substrate 151 and the conductive film 11 are plastically deformed and bent by the force. At this time, the stress and strain of the substrate and the conductive film are related to the thickness of the substrate and the conductive film and the Young's coefficient. When the signal is input, it is easy to cause fatigue damage to the conductive film due to the rebound plastic deformation of the substrate and the cyclical stress. With such a conventional touch panel, the force applied by the substrate during the deformation process will be directly transferred to the conductive film, especially when the input force is excessively or continuously accumulated after tens of thousands of repeated writing inputs. The conductive film U is caused to generate internal stress, which is liable to cause micro cracks or peeling off from the substrate, resulting in a rapid decrease in the conductivity of the conductive film itself, and the touch panel sensing circuit cannot thereby misinterpret or misjudge the input point position and lose the function of the input interface. , reducing the sensitivity of the touch panel.
