Input device detection method

Abstract

The invention relates to an input-device detecting method, which comprises the following steps of providing an input device with a plurality of first sensing lines and second sensing lines; respectively coupling the first sensing lines and the second sensing lines with the anode and the cathode of a power supply, so as to judge whether the first sensing lines and the second sensing lines have short-circuit defects or not; respectively coupling the odd first sensing lines and the even first sensing lines with the anode and the cathode of the power supply, so as to judge whether the first sensing lines have the short-circuit defects or not; respectively coupling the odd second sensing lines and the even second sensing lines with the anode and the cathode of the power supply, so as to judge whether the second sensing lines have the short-circuit defects or not; respectively coupling a grounding line and the first sensing lines (or the second sensing lines) with the anode and the cathode of the power supply, so as to judge whether the grounding line and the first sensing lines (or the second sensing lines) have the short-circuit defects or not.

Description

technical field [0001] The invention relates to a detection method of an input device, in particular to a detection method suitable for an input device with a plurality of induction lines. Background technique [0002] The input device is, for example, a touch panel. People can interact with electronic devices through the input device. With the advancement of technology, the touch panel has been widely used in electronic devices, such as smart phones, tablet computers, ATM cash machines or Computer drawing boards, etc., so people can easily touch the touch panel to generate input signals to the electronic device, thereby improving the convenience of operating the electronic device.

Problems solved by technology

[0003] However, in order to improve the touch sensing capability of the input device such as the touch panel, the sensing lines in the touch panel are closely distributed on a certain area of ​​transparent conductive film, such as indium tin oxide (ITO), or The sensing lines are closely distributed on the metal pattern layer substrate, in which the sensing lines are staggered and closely distributed, so the sensing lines of the input device may have short-circuit defects, thereby reducing the convenience of using input devices such as touch panels

[0004] Among them, the commonly used detection method, for example, is to detect one by one, for example, to detect whether there is a short circuit defect between two adjacent sensing lines, or whether there is a short circuit defect between one sensing line and multiple sensing lines, Although this detection method can accurately detect short-circuit defects, it takes a lot of time to detect short-circuit defects, thereby reducing the performance of the detection input device
