Embodiment approach 1

[0018] Embodiment 1, such as figure 1 Shown is a schematic diagram of the touch panel system of the present invention, which includes a capacitive sensing array 10 for sensing finger touches, a signal processing device for receiving signals from the capacitive sensing array 10 and processing the signals of the capacitive sensing array 10, a receiving The CPU system of the signal processing device, the driving module receiving the signal of the CPU system, and the vibration feedback array 40 receiving the signal of the driving module, and the vibration feedback array 40 transmits the vibration signal to the fingers. Wherein, the driving module is an amplifier, which amplifies the signal of the CPU system, and then transmits the amplified signal to the vibration feedback array.

[0019] together with reference figure 2 As shown, the touch panel 100 includes a vibration feedback array 40, a support frame 50 holding the vibration feedback array 40, a capacitive sensing array 10 ...

Embodiment approach 2

[0021] Embodiment 2, such as image 3 and Figure 4 As shown, it is a schematic diagram of the touch panel system of the present invention, which is different from Embodiment 1 in that the capacitive sensing array and the vibration feedback array are a single module, which is composed of several piezoelectric units 41' isolated from each other. The piezoelectric unit array 40', when the finger touches the touch panel 100', the piezoelectric unit 41' at the corresponding position is deformed due to pressure, and according to the piezoelectric characteristics, voltage signals will be output at both ends of the piezoelectric unit, as long as the voltage signal is collected. The corresponding touch position can be obtained. In the next step, the CPU system sends a vibration signal to the piezoelectric sheet according to the position information, and uses the inverse piezoelectric characteristics of the piezoelectric material to make it vibrate, thereby feeding back to the finger. ...

Abstract

The invention provides a touch panel system which comprises a touch panel, a signal processing unit and a central processing unit (CPU) system, wherein the touch panel senses touch of fingers, the signal processing unit receives touch panel signals and processes the touch panel signals, the CPU system receives signals of the signal processing unit, and the touch panel comprises capacitance sensing arrays; and the touch panel system further comprises a driver module used for receiving signals of the CPU system, the touch panel further comprises vibration feedback arrays for receiving signals of the driver module, and the vibration feedback arrays transmit vibration signals to the fingers. The touch panel system is provided with touch functions.

Description

【Technical field】 [0001] The invention relates to a touch panel system, in particular to a touch panel system with vibration feedback. 【Background technique】 [0002] Touchpad (TouchPad) is currently the most widely used mobile PC mouse. The touchpad is made of printed circuit boards in an array of rows and columns; the printed board and the surface plastic film are bonded with a strong double-sided rubber. is capacitive sensing. A special integrated circuit board under the surface of the touchpad continuously measures and reports this trajectory, thereby detecting finger movement and position. [0003] The touchpad is an essential input device for every notebook computer. The original intention of the system manufacturer is to save users from the trouble of bringing an external mouse, and to realize the dream of mobile office at any time without the need for external devices. However, for most users, the touchpad cannot give the user a good interactive experience due to t...
