New Description: [New Technology Field] This notebook provides an improved capacitive touch sensing structure, especially a capacitor that can set the X-axis and Y-axis sensing traces on the same sensing layer. Touch sensing structure. [Prior Art] The touchpad (TouchPanel) is usually deployed in front of the display screen of electronic products such as mobile phones, cameras, PDAs, etc., in order to improve the convenience of implement control and signal input; and in the 'various types of touch panels, Because capacitive touch panels have the advantages of stable performance and long service life, they are gradually being widely used in communication products (C〇mmunicati〇n), computer products (Computer) and consumer electronics (consumer); It is known that the capacitive sensing structure of the conventional capacitive touch panel includes a 感应-axis sensing layer and a γ-axis sensing layer, so that the X-axis sensing layer is insulatedly disposed inside the touch panel body, and When the χ, γ axis _ layer is separated from the ground and connected to the control circuit, the capacitance effect is generated by the moment when the manufacturer's finger or the conductor touches, so that the hand ♦ finger or the capacitance value can be determined by the change of the capacitance value. The position of the conductor; because the capacitive type of board can be input by fingers, the input operation will follow the 'input operation of the input, and will not let the sulfur have the disadvantage of reversing the stress and deformation, so the disadvantages are caused. The product has stable performance and long service life; however, since the conventional capacitive engraving plate is divided into two different sensing layer planes, the four layers of insulation are stacked and combined into one plate body. Therefore, in the production process of the touch panel, when the χ and γ-rejection stitches disposed on two different planes are stacked and combined, the inaccurate alignment phenomenon often occurs, resulting in the capacitive sensing signal of the touch panel. The sensitivity and accuracy are reduced, and the touch panel is composed of a multi-layered sensing layer and an insulating layer M354119. The thickness of the board is not only thicker but more severely detrimental to the transmittance of the touch panel. The pattern of the stitch portion and the non-track portion (ie, the hollow portion) formed on the plane has different light transmittance, and the uneven light riding on the panel will cause unevenness of the screen image and blur distortion. [New content] Secret to this 'this creation is mainly to provide - a kind of change _ capacitive touch sensing junction. Structure 'It can set the capacitive sense of the X-axis and y minus Ci stitches in the same sense Responding to the layer on the layer to improve the sensitivity and accuracy of the touch-resistance performance. In addition, the number of layers can be reduced, the touch panel can be thinned, and the process can be simplified. reduce manufacturing cost. Another object of the present invention is to provide an improved capacitance pick-up structure that can be used to set the X-axis and gamma-axis sensing traces of the brain structure on the same sensing layer to reduce the The proportion of the non-track portion (that is, the bell-empty portion) on the sensing layer makes the touch panel have a relatively uniform light transmittance, which is disturbed by the sensitivity of the screen. For the above purpose, the improved capacitive touch sensing structure is composed of a first substrate and a second substrate, and the two substrates are bonded to a board by a glue layer; wherein, the first substrate is An insulating sheet having a high transmittance and having at least one capacitive sensing layer on a surface of the first substrate, which is a transparent film having good electrical conductivity, and having a plurality of first axis traces arranged in a matrix Trace) and a plurality of second traces, such that the first and second axis traces are approximately perpendicular to each other, and the respective induction-spots on the respective first axis traces are electrically connected to each other, and The respective sensing units of the M354119 on the second second axis trace are insulated from each other, and the first axis trace and the one end edge of the second axis trace are respectively electrically connected to the metal guides disposed at the edge of the panel and guided to a signal output. a terminal; a jumper conductive layer 'having a plurality of electrical wires disposed along the second axis direction, so that the electrical connections of the two end edges of the electrical wires are respectively electrically connected to the second adjacent trackThe unit is configured to electrically connect the sensing units on the respective second axis traces to each other; a barrier layer having a plurality of transparent insulating masks disposed between the electrical conductors and the capacitive sensing layer A portion other than the electrical connection portion of the electrical lead electrically contacts the capacitive sensing layer; and the second substrate is also an insulating thin layer having a high transmittance, and the periphery of a surface of the second substrate is provided with a non- a transparent frame cover; the glue layer is an insulating transparent adhesive material ′ and disposed between the first substrate and the second substrate. The insulating layer of high transmittance of the first substrate and the second substrate may be selected from the group consisting of glass, polycarbonate (PC), polyester (P〇iythyiene terepi alate, PET), polymethyl propylene a thin plate material of a methyl ester, pmma or a cyclic hydrocarbon copolymer (Cyclic Olefin Copolymer); a conductive transparent transparent film of the capacitive sensing layer, which may be made of indium tin oxide (ITO) or polyethylene A film made of dioxythiophene (PEDOT). The electrical conductor of the conductive layer is a transparent conductive film made of indium tin oxide _) or polyethylene dioxy porphin (PEDOT), or an opaque metal conductor with a diameter less than 2 () _ such as gold wire. Or the silver wire, and the electrical connection portion at the two end edges of the electric wire is set to have a larger contact area than the electric wire, and the effect of electric turning is finely enhanced. The insulating mask of the barrier layer is made of a dielectric constant (4) coffee (4) of about 2 to 4, a high transmittance insulating thin layer material having a thickness of 2/z nm, such as an ink or a polyester M354119 film; The periphery of the insulating mask of the barrier layer is a tapered edge which is gradually thinned. Preferably, the angle of the oblique side is less than 5 degrees. The design of the oblique edge structure is used to electrically connect the conductive layer of the conductive layer. When installed, it can reduce the bending angle of the electric wire installation to improve the stability of the electrical connection structure and greatly reduce the probability of electrical wire breakage. The non-transparent frame cover of the second substrate may be formed by ink printing, coating or coating with color photoresist, organic material or metal sputtering to form an opaque or translucent color frame cover; and the insulating transparent gluing The layer may be a photocurable rubber or a thermosetting rubber. In addition, a transparent conductive layer, such as a transparent conductive material, such as an oxidized marriage or a red epoxide (pED〇T) material, may be disposed on one surface of the plywood body of the first substrate and the second substrate. By using the guide as an electromagnetic screen rider, the interference or damage of the electrostatic or EM (Electro Magnetic Interference) is maintained, and the normal operation of the capacitive touch panel is maintained. This creation is limited to the lion style of the Zhuang, and it is very popular. For those skilled in the art, the 'after the reference to the above system' can have more improvement and change, which is related to the same creative spirit. Any modifications or changes to this creation should still be included in ==意_叙龄' and a little more. The transfer of the Lin cake.
