SUMMARY OF THE INVENTION The present invention provides a proximity sensing panel that proposes a substrate in which a proximity sensing unit is formed on a panel. This panel is different from the previous touch panel, and it does not need to touch the proximity sensor panel to generate a sensing signal. At the same time, the number of times the panel is touched is reduced, and the product life is extended. The invention further provides a proximity sensing panel comprising: a substrate, at least one proximity sensing unit 7L and at least one system. The thief's fresh element axis is in New Zealand, and the near-honest field responds to the object and generates a corresponding one of the sensing signals. The sensing circuit is connected to the proximity sensing unit for receiving the sensing signal to generate a control signal. The above and other objects, features, and advantages of the present invention will become more apparent and understood. The proximity sensing panel includes a substrate and at least one proximity sensing unit. 201145114 By directly forming the proximity sensing unit in the substrates of different panels, the applied substrate has a proximity sensing function and can remotely control the human interface of the panel to achieve better human-computer interaction. At the same time, in the case of different proximity sensing panels, the components disturbed by environmental influences can be reduced. The proximity sensing unit is formed in the panel, and the process of making the proximity sensing unit can be integrated into the manufacturing process of the panel without affecting the process of the original panel manufacturing process, so that the proximity sensing unit can be greatly reduced. the cost of. Please refer to FIG. 4, which is a functional block diagram of the proximity sensor panel 200 of the present invention. The proximity sensor panel 200 includes a panel 210, at least one proximity sensing unit 230, and at least one sensing circuit 240. At least one proximity sensing unit 230 is formed on the substrate, and the corresponding proximity sensing signal is generated according to the proximity of the object 1〇, and the size of the proximity sensing signal is changed according to the distance of the object 10. The sensing circuit 240 is configured to receive a proximity sensing signal to generate a control signal. The microcontroller 250 is coupled to the sensing circuit 240 for receiving control signals and performing calculations to generate coordinate information (Χ, Υ). The controller 240 can use the coordinate information (Χ, γ) to judge the gesture direction, for example, the object is left to right, right to left, left oblique to right oblique, right oblique to left oblique, and Down to the bottom, up to the top, two objects to enlarge, two objects to shrink, and so on. In this way, the user's interactive gestures with various panels can be realized. The proximity sensing unit 230 is an inductive proximity sensing unit that generates an inductive signal according to a change in inductance. That is, the substrate may be a glass substrate, a plastic substrate or a color filter substrate. Inductive proximity sensing units use the distance of the object to change the size of the sensing signal. The magnitude of the 'inductive signal' is the change in inductance. The oscillating circuit in the sensing circuit 240 changes the amplitude/amplitude of the oscillating frequency by the change of the inductance, and outputs a control signal to the microcontroller 250 according to the oscillating frequency/amplitude. The proximity sensing unit 230 can also generate a capacitive proximity sensing unit for the change of the capacitance. That is, the substrate may be a glass substrate, a plastic substrate or a color filter substrate. The capacitive proximity sensing unit changes the size of the sensing signal by using the distance of the object, wherein the size of the sensing signal is a change in capacitance. The oscillating circuit in the sensing circuit 24 changes the magnitude of the solution/amplitude according to the change of the electric material, and generates a control signal according to the magnitude of the recording rate/amplitude to output to the microcontroller 250. Among them, the capacitive proximity sensing unit includes a self-valley proximity sensing unit and a mutual capacitive proximity sensing unit. Self-contained proximity sensing unit A uses at least one electrode for driving and sensing. The mutual capacitance proximity sensing unit uses at least two electrodes arranged to drive and detect. Wherein, the proximity sensing unit of the proximity sensing panel is arranged in a rectangular shape, a diamond shape, or an arbitrary arrangement.
