[Prior Art] With the development of optoelectronic technology, the proximity switching device has been widely used in different machines, such as: smart phones, transportation ticket purchasing systems, digital cameras, remote controls, LCD screens, etc. . Common Proximity Devices include, for example, Proximity sensors and touch panels. Wherein, the proximity sensor operates in a manner that when an object is in proximity to the sensing range of the sensor, the proximity sensor senses that the object is close to the proximity by touching the object or not touching the object. The location of the sensor. The proximity sensor converts the induced signal into an electronic signal, and the system or the machine responds appropriately according to the electronic signal to achieve the purpose of controlling the state of the system. The touch panel is used to calculate the coordinates of the touch, such as the calculation of single touch coordinates or multi-touch coordinates. • Proximity sensors, also known as proximity switches, are used in many LCD TVs, power switches, appliance switches, access control systems, handheld remote controls and mobile phones. In recent years, these devices and devices are indispensable. One of the roles. It is responsible for detecting the proximity of an object so that the controller knows where the current object is. In the case of home appliance applications, the proximity sensor is used in a large number of sources to control the light source. As long as it is close to the proximity sensor or touches the proximity sensor, the light source can be turned on or off according to the sensing signal source. The types and proximity of the proximity sensors are rectangular, square, cylindrical, round, groove, and multi-point. According to its principle, it can be divided into 4 types of 3 201145128: inductive, capacitive, photoelectric and magnetic. As can be seen from the above, the application fields of the proximity sensor and the touch panel are extremely different, and are respectively used as the calculation of the switch and the touch coordinates. In the current technology, there is no integrated application technology for how to handle both proximity sensors and touch panels. Therefore, how to integrate both the proximity sensor and the touch panel', and thus the short-distance spatial sensing function of the proximity sensor and the touch coordinate detection function are integrated, thereby making the electronic device greatly increase the application function possibility. research direction. SUMMARY OF THE INVENTION The present invention provides a capacitive proximity sensing and touch detection device, comprising: a capacitive touch panel for detecting that an object is close to the generated one of the sensing signals and the object is touched. And a control unit, connected to the capacitive touch panel for generating a control data according to the sensing signal, and calculating a touch coordinate of the object according to the touch signal. The invention provides a capacitive proximity sensing and touch detection method, which is applied to a capacitive touch panel' comprising the steps of: setting a proximity sensing output mode; opening a proximity signal extraction mode; detecting - The object is close to the capacitive touch panel, and the output-sensing signal is used; according to the sensing signal, the touch control coordinate data is touched, and the touch object is touched by the gamma object, and the touch coordinates of the object are calculated and output. The above and other objects, features, and advantages of the present invention will become more apparent. The preferred embodiments of the present invention will be described in detail below. Most of the touch panels are applied, touch the coordinates, and the anger is measured. Therefore, the touch panel is made as a thin switch. The hair crane uses the proximity sensing function of the capacitive touch panel itself as a proximity sensor switch, that is, the capacitive touch panel as a whole 201145128 can be used as a close-view capacitor, a lion object, a palm of the hand. The sensing signal generated by the touch panel is used as the control data for controlling the motion of the screen. First, the touch 彳 κ '其林发__'s touch button frame is thin, including: touch panel 12, touch The control sensing circuit 14, the proximity sensing circuit 16, the control circuit 祀, the electrode 20', the touch sensing circuit 14, the proximity sensing circuit 16, and the control power (4) may be collectively referred to as a control unit 22^β touch panel 12 is substantially a capacitive touch panel having four electrodes 2 〇 for connecting the φ contact control sensing circuit 14 to make the touch panel 12 have a uniform electric field. The touch panel η further has a layer sensing layer (not drawn), also connected to the touch sensing circuit 14, for the induced current generated by the side object touches, and then the object _ collision coordinates. Because the capacitive touch panel before the object touches the touch panel That will produce an amount of induction. Therefore, usually in order to prevent The external noise and unnecessary accidental events will be judged by -_(Thresh.丨(1) as the "touch" or not when making the touch coordinates. That is, for non-touch The event, because its coordinates can not be accurately obtained 'and' because of the unreal touch of Lin, the current control panel technology * is handled. The invention specifically calls this - the past product as a problem thief should be signaled, so that The capacitive touch panel obtains a new application. The proximity sensing circuit 16 is connected to the touch sensing circuit 14, and the electrode 20 of the touch panel 12 is connected in parallel to detect the object of the touch panel 12. The sensing signal is used to output a control data; and the touch sensing circuit 14 is used to calculate the coordinates of the object touching the touch panel 12.

In another embodiment, the proximity sensing circuit 16 can be a single chip, and the touch sensing circuit 14 and the control circuit 18 can form a single chip. In another embodiment, the proximity sensing circuit 16, the touch sensing circuit 14 and the control circuit 18 can together form a single chip. That is, the function of the proximity sensing circuit 16 can be performed by the touch sensing circuit 14.

That is, as long as the object 2 enters the touch panel 12# proximity sensing range D7, the proximity sensing circuit 16 outputs the representative D7 # sensing signal; when entering the proximity sensing range D6, the proximity sensing circuit 16 outputs the representative D7. Inductive signal; the rest are mixed. Also, the near thief test circuit 16 outputs different proximity sensing signals depending on the position of the object Dx. This is a multi-order proximity sensing signal. The output of the multi-level proximity sensing signal allows the system to know the depth of the object. 201145128 Please refer to FIG. 3, which is a schematic diagram of a near-end data of a touch detection device of the present invention.
