The 4 is filled with a known charge. When the finger touches the board, 'because the human body is charged, the panel will be touched: less, Causes the voltage to drop 'so the detected charge is changed to the touch position; and the wiring and the electric 2 flexible circuit board (FPC) provided on all the edges of the panel should be the stationary operating area, but physically it is two parallel The board generates capacitance, and the line and the line are also = impurity capacitors. Because the driving method of the touch panel is that the side charge changes, the above-mentioned static operation area will be misjudged with the touch of the finger, resulting in an operation failure. Stable; again, the capacitor = zoned wafer (10) has the function of detecting charge fluctuations, and uses the X-axis and y-axis values of the sub-measurement position to transmit data to the host (10) ST) through the industry standard interface, and the host receives Capital After the message, 1 changes the position to judge the user's application actions at the time, such as writing, clicking and drawing, etc., thereby launching related application functions displayed on the LCD screen. 'This host can have a separate intrusive system and Applications such as arm, x86 CPUs with WIN CE or LINUX 〇s, etc.; however, because electromagnetic interference (EMI) 'electromagnetic interference (EMS) has electric and magnetic fields M357659 7 ηη, field interference factors will affect the driving ic Acting L^-ΐϋ The upper and lower layers are added—the method (4) shielding layer is used as the product yield', which indirectly makes the design of the product difficult and the thickness of the calving increases, and causes the problem of rising cost. The driving force of the touch panel 11 is driven by the electric valley type hard panel. The impedance and the capacitive reactance of each line are strictly required. Therefore, the position of the driving wafer 12 is extremely high. The conventional technology system will drive the wafer. 12 is fixed by the technology of SMT on the specific position of the under-printed circuit board 13 or the main board 14, which is fixed on the touch panel or fixed on the system flexible printed circuit board of the liquid crystal display (LCD), but Nowadays, the real mass production: the manufacturer chooses the design of the former. 'Because the former needs to control the line impedance is the smallest; but 'because the picking position of each driving chip 12 on the market is different. 贞 面 面 面 电容 电容 电容 电容 电容The impedance of the line and the capacitance are not large, and the difference in the step size is quite large, so that the capacitive touch surface and the driving chip 12 cannot be independently configured to cause the sensitivity of the touch panel to be optimized, so when an abnormality occurs in the process, Regardless of which electronic components are replaced, they must be readjusted to maintain the product f, resulting in production and sales limitations. [New Content] In view of this, the purpose of the present invention is to provide a touch panel mounting structure to solve the above-mentioned problems of the prior art. According to the purpose of the present invention, a touch panel structure is proposed. The structure is suitable for liquid crystal glory: the structure includes M357659 - touch panel and driver chip (IC), capacitive touch The panel has a bonding area.

A COG (Chip〇nGlass) technology is bonded to the bonding area ^3. The technology of the c〇G can correspond to materials such as hard glass, flexible substrate or resin, so that the original capacitive touch panel 21 and the driving chip can be saved. The cost of the 22-bit flexible circuit board (FPC); further, the driving chip 22 extends a first wiring group 221 and a second wiring group 222 to be electrically connected to the capacitive touch panel 21, because the driving chip 22 The 7 M357659 of COG is used to bond to the capacitive touch panel 21, so the length of the line of the first wiring group 221 - the ingredient 222 is reduced, thereby reducing the interference or interference of the line resistance γ. And resistance = ''乂2) 3⁄4 control panel low', so drive chip 22 and capacitive touch surface When the capacitive touch panel 21 is in operation, the capacitive touch panel 21 is touched by a finger or a conductor to instantaneously generate an internal charge change, and the driving chip 22 is transmitted through the first wiring group 221 and the second. The group 222 detects the change of the surface charge to generate a voltage difference signal, and the driving chip 22 determines the touch position according to the pressure difference, and connects with the host by the industry standard interface SPI I2C, RS232, etc., according to the change of the position of the host. The user's current application actions, such as writing, clicking, and drawing, are used to activate the related application functions on the LCD screen. Please refer to Figure 3, which is a schematic diagram of the evasive design of the electromagnetic interference of the structure of the touch panel of the present invention. The driving chip 3 includes an analog area 311 and a digital area 312. When the sensing terminal pin 314 (SENSORPIN) of the specific area 31 is fan-out (FAN0UT), the sensing terminal pin 314 is disposed on the same side, and the digital position is The communication portion of the area 312 and the host (HOST) is disposed on the opposite side of the pin (PIN) of the analog area 311; in order to avoid electromagnetic interference (EMI), the driver of the liquid crystal screen or the driver of the liquid crystal screen interferes with the driving chip 31, that is, A planar region 32 is formed on the driving chip 3 and its periphery.
