Description

M342556 VIII. New description: [New technical field] This new 疋 has a panel device, especially a touch panel device mounted on an electronic device. [Prior Art] In recent years, due to the rapid development of the touch panel, the production cost has been greatly reduced, and it has been widely used in consumer electronic products, such as mobile homes, digital cameras, and satellite navigation devices (GPS) K. Electronic products with display screens such as Music Box (Mp4), Personal Digital Assistant (PDA), etc., can directly attach the touch panel to the outer surface of the screen, allowing the user to touch the touch Panel to operate electronic goods. As shown in FIG. 1 , a known touch panel device is mounted in an electronic device not shown, and includes: an upper substrate n and a lower substrate 2 spaced apart from each other, and an upper substrate 11 a bottom electrode layer 13 , a lower electrode layer 14 disposed on the top surface of the lower substrate 12 , a gas chamber 15 formed between the upper and lower electrode layers 13 and 14 , and a bonding between the upper and lower substrates u and 12 The insulating layer 16 of the gas chamber 15 is spaced apart, and an adhesive layer 17 for bonding the lower substrate 12 to the screen 18 of one of the electronic devices. The upper and lower electrode layers 13 and 14 are formed by depositing a conductive material, such as Indium Tin Oxide (ITO). When the upper substrate U is touched, the upper electrode layer 13 contacts the lower surface. At the electrode layer 14, a signal for controlling the electronic device can be transmitted. Here, the upper electrode layer 13 and the lower electrode layer 14 are spaced apart from each other to exist in the gas cell 15, thereby reducing the film interference of the upper and lower electrode layers 13, 14 and the Newton ring (^-^) generated by the M342556. In order to space the upper and lower electrode layers 13, 14, it is necessary to use an insulating layer i6 of a thickness 黏 to adhere between the upper and lower substrates η and 12, but the insulating layer 16 is relatively easy to apply, and the insulating layer 16 is relatively easy to apply. After the adhesive layer 16 is adhered, the upper and lower substrate cores 12 are not flattened, and the upper and lower electrode layers 13 and 14 are also not flat, resulting in the thickness of the gas chamber 15 between the upper and lower electrode layers 13 and 14 or The thickness is not large enough, so it still produces severe interference fringes of Newton's rings. [New content] This new type of eye #, is to provide a touch panel device with a thickness of uniform gas to effectively eliminate interference fringes. Therefore, the touch panel device of the present invention comprises: a lower conductive unit, an upper conductive unit, a gas chamber jointly defined by the upper and lower conductive units, and an insulating rubber layer. The lower conductive unit includes a lower substrate and a lower conductive layer overlying the top surface of the lower substrate. The upper conductive unit includes an upper substrate spaced above the lower substrate and an upper conductive layer overlying the bottom surface of the upper substrate toward the lower conductive layer. One of the upper and lower conductive units further includes a flat portion spaced apart from the other conductive unit, and at least one protrusion protruding from the flat portion toward the other conductive unit. The insulating adhesive layer is disposed on the protruding portion and is used for bonding the upper and lower conductive units. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. M342556
