Problems solved by technology
[0003] Among them, the touch panel can be divided into resistive touch panel, capacitive touch panel, optical touch panel, etc., and the general resistive touch panel can only be used to detect the user due to its structure. If the user performs a multi-touch operation on the resistive touch panel, it will not be correctly interpreted, so the application of the resistive touch panel will have its limitations

The invention provides a device for detecting a resistive touch panel, comprising a resistive touch panel and more than one sensing module. The resistive touch panel comprises more than one sensing block, and each sensing block consists of a primary sensing element and a secondary sensing element. The more than one sensing module are respectively corresponding to the more than one sensing block and are used for detecting whether the more than one sensing block are touched by users. Each sensing module comprises a voltage source, an adjusting unit, a controller and a sensing unit. The adjusting unit is coupled with the voltage source for generating an electric current. The controller is used for selectively coupling the secondary sensing element with an earth terminal. The sensing unit is used for detecting the voltage of the adjusting unit and judges whether the sensing block is touched by the user according to the voltage.
Description
Technical field: [0001] The present invention relates to a detection device for a resistive touch panel, in particular to a detection device for a resistive touch panel capable of detecting multi-touch. Background technique: [0002] Due to the great improvement of related technologies of touch sensing in recent years, and its great convenience in use, various touch sensing technologies have been widely used in various electronic products. Among them, the touch panel is widely used in various electronic products due to its advantages of small size, low cost, low power consumption and long service life. [0003] Among them, the touch panel can be divided into resistive touch panel, capacitive touch panel, optical touch panel, etc., and the general resistive touch panel can only be used to detect the user due to its structure. If the user performs a multi-touch operation on the resistive touch panel, it will not be correctly interpreted. Therefore, the application of the resi...
