New description: [New technical field] The present invention relates to a touch panel, in particular to a multi-touch panel structure. [Prior Art] - Refer to the first figure 'General view of the capacitive multi-touch® board structure. As shown in the first figure, the conventional multi-touch panel 1 structure comprises an outer layer 10 and a touch sensing sheet 2, and is integrally combined with a transparent optical adhesive 3〇. The outer mirror surface 10 includes an upper substrate u and an ink pattern 15, and the touch sensor sheet 20 includes a lower substrate 21, a first matrix electrode 23, a second matrix electrode 25, a metal line 27, and a protective layer 29. The upper substrate u and the lower substrate 21 are glass or transparent plastic; the ink pattern 15 is formed on the upper substrate u as a design pattern printed by at least a layer of ink to cover the underlying lines and to increase the design aesthetic; - the matrix electrode 23 and the second matrix electrode 25 are transparent conductive - electric (four) usually Wei _ _), divided into two surfaces of the lower pure 21, the metal layer is formed on the outer side of the matrix electrode above the ink miscellaneous, with a gold shoulder The way of the wire shaft rib reduces the impurity of the second scale electrode, and the money is connected to the external soft = road plate; the protective layer is usually a oxidized pin permeable layer to protect the metal layer. In the capacitive multi-touch panel structure in the first figure, the lower substrate serves as a dielectric material between the =electrode 23 and the second matrix electrode 25 to generate a snubber effect, but the thickness of the currently used glass is usually 〇 After the collar is __-M383779, the first and second matrix electrodes are too large, so that the capacitance signals formed by the fingers on the first matrix electrode and the second matrix electrode are too different. Large 'not easy to identify' needs to be compensated by a more sophisticated decoding integrated circuit (IC). In addition, each layer of oxidized steel tin on the two sides of the lower substrate is incompatible with the conventional thin film transistw (TFT) process equipment or color filter (C〇1〇r fllter 'CF) process equipment. And it is usually necessary to deposit the protective layer 29 in a semiconductor process to protect the metal line π, so that the production efficiency is low, and the manufacturing cost is quite expensive.参阅 Refer to the second figure for another cross-sectional view of a capacitive multi-control panel structure. As shown in the second figure, in order to improve the above disadvantages, a structure of another touch sensing sheet 40 is formed, including a lower substrate 4, a first matrix electrode, a second matrix electrode 45, a metal circuit 4, and a dielectric. The layer 49 is formed between the dielectric layer 49 and the lower substrate 41 and is connected to the second matrix electrode pad. The dielectric layer 49 is replaced by the _ in the TFT process. Lower substrate (glass) dielectric layer. Although this structure can be applied to the existing thin film $crystal processing equipment, and the distance between the first-turn electrode and the second-pole 2 electrode 45 is reduced, the thickness of the dielectric layer is too thin due to the TFT process, and V is used. The finger capacitance of the person is too weak, and it is necessary to reduce the width of the partial lines of the two electrode moments ^3 and 45. The fine action is to use a precise lithography process to fabricate the thin line width electrode matrix, and the number of layers is too large. The waste of process costs, and the use of metal lines, the product reliability is poor. Further, referring to the third figure, a schematic view of the connection of the conventional matrix electrode and the metal line 4 2 is shown. As shown in the third figure, referring to the first and second figures, the friends 27, 47 are formed between the lower substrate 21 or the lower substrate μ and the dielectric layer 49 to connect the second matrix electrodes 25 or 45, For the convenience of design, the width a is smaller than the interval width b after (4), and the process yield is poor. [New content] The purpose of this creation is to provide a structure of a capacitive multi-touch panel comprising an outer layer lens and a touch sensor sheet, and a transparent optical glue. . Adult. The outer lens comprises an upper substrate, a first matrix electrode, an ink pattern and a conductive line, and the butterfly substrate comprises a lower substrate and a second matrix electrode. The structure of the electric valley type multi-touch panel is formed by forming the first matrix electrode and the conductive line in the outer layer lens, and the conductive line using the conductive adhesive material with low chemical activity is not easy to be subjected to occupation and chemical dependence, so that the reliability is obtained. Increased, and may not have to be deposited in a semiconductor or TFT process. (4) The optical glue also serves as a bonding and dielectric material to reduce the number of layers of the structure. In addition, the electrode turn and circuit are formed by printing plus the residual method, and the cost is much lower than that of the semiconductor or TFT lithography plus etching process. In addition, the manufacturing method of the capacitive multi-touch panel can be completed by using the existing printed circuit board processing equipment, the technology is mature, and has two more production efficiencies.
