Patent ID: 8294684

Claim:
A device for detecting connections of a 4- or 5-terminal resistive touch panel, comprising: five terminals arranged in parallel comprising a first, a second, a third, a fourth and a fifth terminal, wherein at least four of the five terminals are connected to a touch panel; and a detecting unit, comprising: providing a first high potential and a first low potential to the first and fifth terminals, respectively, and determining whether the touch panel is a 4- or 5-terminal resistive touch panel based on whether there is an open or closed circuit between the first and fifth terminals; when the touch panel is a 5-terminal resistive touch panel, the first and fifth terminals being connected to the same layer of the 5-terminal resistive touch panel; wherein a second high or low potential is provided via an electrical element, whether there is an open or closed circuit between the terminals provided with the second high and low potentials is based on a signal between the electrical element and the terminal coupled to the electrical element, the resistance value of the electrical element is larger than that of the touch panel.
