[0001] The present invention relates to a signal processing structure of a touch screen, and more particularly to a signal processing structure of a capacitive touch screen and a touch panel display. [Prior Art] [0002] Touch is the most important way of human perception, and the most natural way for people to interact with machines. Touch screen development has been widely used in many fields such as personal computers, smart phones, public information, smart home appliances, and industrial control. In the current touch field, there are mainly resistive touch screens, photoelectric touch screens, ultrasonic touch screens, and flat capacitive touch screens. In recent years, projected capacitive touch screens have developed rapidly. [0003] Resistive touch screen is still the 'mainstream product on the market, but the structure of the two-layer substrate of the resistive touch screen makes the touch screen very reflective when the touch screen and the display panel are stacked together. Affects the display quality such as brightness, contrast, color saturation, etc., so that the overall display quality is greatly reduced, and the brightness of the backlight of the display panel is increased, and the power consumption is greatly increased; " The analog resistive touch screen also has a positioning drift. Problem, position calibration is required from time to time; In addition, the operation of the resistive touch screen electrode contact makes the touch screen have a shorter life. [0004] Infrared touch screens and ultrasonic touch screens do not affect the quality of the display. However, infrared touch screens and ultrasonic touch screens are costly, and water droplets and dust can affect the reliability of touch screen operation, especially red form number A0101 Page 3 of 54 M406771 External touch screen and ultrasonic type The touch screen mechanism is complex and consumes a lot of power, making the infrared touch screen and the ultrasonic touch screen basically impossible to apply to portable products. [0005] The structure of a single-layer substrate of a planar capacitive touch screen makes the touch screen have little effect on display quality when the touch screen and the display panel are stacked together. However, the planar capacitive touch screen also has the problem of positional drift, and position calibration is performed from time to time; water droplets also affect the reliability of the touch screen operation; in particular, the flat capacitive touch screen consumes a large amount of power and costs, and also allows Planar capacitive touch screens are basically not available on portable products. [0006] The projected capacitive touch screen has little effect on the display product. The sensitivity is also high. However, the projected capacitive touch screen has high requirements on the resistance value of the detecting electrode line, so that the detecting electrode line of the projected capacitive touch screen used in combination with the display panel cannot be transparent only with low conductivity such as ITO. The electrode layer also has a high-conductivity electrode layer such as a metal, which is complicated in manufacturing technology and high in cost, and is particularly expensive in terms of a large-sized or even a large-sized touch screen. [0007] The projected capacitive touch screen is not a true digital touch screen. The positioning point needs to undergo complicated calculations. The distributed capacitance in the manufacturing and use environment will affect the reliability of the touch screen operation, display driving signals and other power. Signal interference will affect the operation of the touch screen. In the case of multi-touch screens, in order to eliminate the non-real touch positioning points commonly known as "ghost points", the "touch" of real touch positioning is obtained, and the operation of the simulation calculation is performed. The amount is even larger, the requirements for driving the wafer processing speed and processing data are higher, and the power consumption of the system is also increased. Form No. A0101 Page 4 of 54 [0008] In addition, in order to make the touch screen easy to use, the sensitivity of the touch screen is high enough. 'The sensitivity is high, it is easy to cause false touch, and the touch action is impossible. It varies depending on the strength of the operator's finger touch. [0009] In order to improve the complexity of the production of the capacitive touch screen, the cost is high, and the application number is 200810133417.X "a touch panel display", and the application number is 200910140965.X "a digital capacitive touch screen" And the Chinese patent of "a capacitive touch screen" with application number 20091 0205206.7 proposes a true digital capacitive touch screen structure, so that the touch signal generated by the touch screen is more easily distinguished in space. [New Content] [0010] The present invention is a structure for processing touch signals and data in order to realize a multifunctional and easy-to-operate digital capacitive touch screen. The touch signal refers to before digital/analog conversion. The analog signal, or the number k after the digital/analog conversion, the method, condition and result of the analog signal or digital signal measured by Ma Dongfu.
