New description: [New technical field] The creative material--the structure of the plant, the special signal of the control panel, the improvement of the assembly structure of the transmission cable. [Prior Art] 目 ® 板 ej ej ej ej — — ; ; ; ; ; ; ; ; ; 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性 性It greatly improves the goodwill of the communication interface between people and machines, and improves the efficiency of input operations. The general touch panel structure is slightly included - the transparent substrate is provided with touch money on the substrate. The touch sensing area (four) of the central portion of the towel is set as the touch sensing area and the surrounding area is miscellaneous for the line area. (10) A plurality of signal lines connected to the touch sensing area are provided, and a difficult part of a signal contact is arranged in the line area of the button width, so that each of the shouting functions is connected to each signal in the lap joint. The point of the 'secret connection can be bonded to the -Xinlin transmission line 4, and the 6-in-one _L electrical contact is divided into two parts, according to which the touch area can be controlled. The signal is transmitted through the 3-wire, service transmission transmission service signal processing circuit. When the assembly is used, the substrate of the touch panel is stacked on the front of the liquid crystal display ([(3)) or the LCD display (LCM). This transfer age bend is attached to the back of the LCD or LCM. However, the design of today's electronic products is trending with lightness and shortness. The product structure is more and more sophisticated, and the design of the exterior is changing more and more. Especially in the design of the panel, it is always hoped that the display area of the county and the area of the operation area will be more The larger the frame, the thinner and smaller the frame is. For the purpose of meeting the trend requirements, the M443226 must reduce the width of the line area around the edge of the touch panel. In particular, it affects the line area with the lap. To be serious, this will severely compress the cloth a and space of the signal wire and cause the area of the lap to become smaller, which will result in higher precision of the process, higher difficulty in production technology, and lower yield. When the lap portion with a small area is overlapped with the signal transmission cable, the assembly accuracy is poor, the adhesion stability is not reliable, and the transmission performance of the touch signal is problematic; and the combined structure of the touch panel is The signal transmission cable is electrically connected to the signal contact in the circuit area, so the head end portion of the signal transmission cable is overlapped and attached to the substrate and The bottom surface of the stack of the touch sensor is either fixed between the substrate and the stack of the touch sensor, but usually the signal transmission line is a flexible printed circuit board (FPC). The thickness of the FPC lining is usually above 〇15mm', so the ridges of the signal transmission line on the bottom surface of the touch panel will be raised, but the bottom surface of the touch panel should be mounted on the LCD/LCM. Therefore, the aforementioned convex portion will cause the wire to be uneven, especially in the panel installation of the common flat-type electronic products (such as iph (me, wish); The convexity is more than (4) subjected to large compressive stress from the outside, resulting in a phenomenon that the bump _ number contact or signal is less than _ injury, resulting in poor communication quality. [New content] In view of this, the creation is for touch The assembled structure of the signal transmission cable of the board provides an improved design. The main purpose is to extend the touch sensing (4) contact point overlapping portion from the circuit area to the substrate H and then to the external lap portion and the signal transmission cable group. Connected, so it can be reduced The layout space of the sensor circuit area reduces the width of the border of the touch panel and enlarges the area of the touch operation area, and the connection part of the lap joint and the signal transmission line is outside the substrate. Therefore, there is no protrusion on the bottom surface of the substrate, which causes stress damage and installation problems. The present invention also provides a signal transmission cable assembly structure of the touch panel, which connects the wire signal contact portion of the touch sensor. The extension is disposed outside the substrate, so that the installation area of the lap portion is not limited, so that the installation area of the lap portion can be enlarged, and the touch sensor and the signal transmission cable can be combined and assembled accurately. The advantages of the connection are stable, and the technical difficulty of the production can be reduced, and the product yield is improved.

In particular, 'a bonding pad is provided on at least one surface of the lap portion'. The lap pad prevents the signal contacts and the signal wires on the surface of the lap from being scratched and provides Auxiliary support force, at the same time, protects the circuit layer from bending, avoiding the situation that the lap joint is sharply broken when it is bent; the lap pad can be made of plastic sheet or film with flexibility and insulation, such as poly Preferably, the thickness of the lap pad is 60 um or less, of a sheet or film of carbonate (PC) or polyester (ΙΈΤ). This will further clarify other functions and technical features of the present work, which will be realized by those skilled in the art after reading the description in the text. The touch panel of the present invention mainly includes a transparent substrate, a transparent touch sensor 2, and a signal transmission cable 3; wherein the substrate 1 is a A high-permeability 'thin plate' with excellent mechanical strength is selected from various glasses, polymethylmethacrylate (PMMA), and polycarbonate (p〇iyCarb〇nate, Pc).
