Description of the Invention: [Technical Field] The present invention relates to a structure of a touch panel, and more particularly to a touch pattern structure of a capacitive touch panel. [Prior Art] Modern consumer electronic devices are often equipped with a touch panel as one of their input devices. In order to meet the requirements of light, thin, short and small, the touchpad is integrated with the panel to form a touch panel for user input. The touchpad can be classified into four types: resistive, capacitive, sonic, and optical depending on the sensing principle. The technical principle of the touch panel is to detect the voltage, current, sound wave or infrared line according to different sensing methods when the finger or other medium touches the screen to measure the coordinate position of the touch point. For example, the resistive type uses the potential difference between the upper and lower electrodes to calculate the position of the pressure point to detect the touch point. The electro-optic touch panel detects the coordinates of the generated current or voltage by utilizing a change in capacitance caused by electrostatic coupling between the four non-aligned transparent electrodes and the human body. A schematic diagram of the structure of the contact panel. A conductive plate (3) is arranged on the substrate 28 and is formed in a read-and-forward manner - a specific shape diamond shape). As shown in Fig. 1, the conductive plates 3 are formed in an array in the horizontal direction and respectively have conductor lines which are formed into a second array from the stalks, and have conductor turns, respectively, Y2, 201239714 Y12. Each of the conductor wires χι_χΐ2, Y1-Y12 has a plurality of electrode plates which are arranged on the substrate in an interlaced manner without overlapping. Each of the conductor wires Y1-Y 12 has a diamond-shaped metal plate having at least two edges adjacent to the conductor XI-X12 metal plate, and at most four edges adjacent to the conductor wire XI-X 12 metal plate. At the same time, each of the conductor wires XI_χι 2 has a shape of at least two edges adjacent to the metal wires of the conductor wires Y1_Y12, and at most four edges are adjacent to the metal wires of the conductor wires Υ1_Υ1 2 . When a driving circuit (not shown) generates a driving signal, a detecting circuit (not shown) detects the side sensing electric valley between the conductor line Υ1-γ12 and the conductor line X丨-X丨2. The amount of electric field change used to detect coordinates. 2 is a schematic view showing the structure of another conventional capacitive touch panel, in which conductive plates are arranged in a metal on the upper and lower sides of a substrate. As shown in FIG. 2, the conductive plates form a first array in a horizontal direction below the substrate and have conductor coils 1, 2, χ 3, ..., respectively, and a second array is formed in a vertical direction above the substrate. Each of the conductor lines Y1, Υ2, Υ3".., each of the conductor lines χ 丨, χ2, χ3, ..., γι, γ2, Υ3'... is arranged alternately and overlappingly. When a driving circuit 2 〇 generates a When the signal is driven, a detecting circuit 22 detects the coordinates by detecting the amount of electric field change of the peripheral sensing capacitance between the electrode plate and the electrode plate. FIG. 3 is a schematic view of the conventional capacitive touch panel used in FIG. As shown in Fig. 3, when there is a grounding conductor or a finger close to the conductor wire ¥2, when the finger directly touches directly above the conductor coil 2, as shown by the circle in Fig. 3, due to the large sensing capacitance, the Detect The measuring circuit 220 can correctly detect the touch of the finger. When the finger touch is not directly above the conductor line ¥2, as shown in Fig. 3, the sensing area is about /xd, which is farther than the touching circle. 201239714 area at a time is small 'so the sensing capacitance is greatly The detecting circuit 220 may not correctly detect the touch of the finger. Therefore, there is still room for improvement in the touch pattern structure of the conventional capacitive touch panel.

As shown in Fig. 10, when the finger directly touches directly above the conductor line ¥2, as shown by the circle C in Fig. 10, since the sensing capacitance is large, the detecting circuit can correctly detect the finger touch. When the finger does not touch directly above the first direction conductor line 132, as shown by the circle D in FIG. 10, since a plurality of first conductive units 13 are generated in the first direction conductor line 132, the sensing area is approximately 6 x/zXd+SxGxdHx/jXc^xGxd, far larger than the sensing area of the conventional technology / xd (%3x/2xd+2x/0d+2x/vxd) is large, so the sensing capacitance is greatly increased by 8 201239714 The circuit can easily detect the touch of the finger correctly. Therefore, the distance between the first direction conductor lines 132 in the present case can be increased, and the number of the first direction conductor lines 132 and the second direction conductor lines 152 on the unit area can be reduced to save costs. It can be seen from the above that the present invention is not surprisingly different from the conventional techniques in terms of purpose, means and efficacy, and is extremely practical.
