Abstract
A device and system for detecting a touch panel are used for detecting a metal mesh on the touch panel, where row direction channels and column direction channels on the metal meshes each include a plurality of touch units which are connected with each other. In the device for detecting a touch panel, a signal transceiving component includes a signal generating unit and a signal receiving unit, which are configured to be arranged on the same side of the metal meshes in preset relative positions, and send and receive a signal through capacitive coupling with the metal mesh, respectively; a defect detecting unit is configured to detect each of a plurality of touch units in the metal meshes based on a detection signal received by the signal receiving unit.
Claims20
A device for detecting a touch panel, and further for detecting a metal mesh on the touch panel, the device for detecting the touch panel comprising:
- a signal transceiving component that is movably arranged relative to the metal mesh, and comprises a signal generating unit and a signal receiving unit, wherein the signal generating unit and the signal receiving unit are configured to be arranged on the same side of the metal meshes in preset relative positions, and send and receive a signal through capacitive coupling with the metal mesh, respectively;
- and
- a defect detecting unit that is configured to detect whether each of a plurality of touch units in the metal mesh has a defect based on a detection signal received by the signal receiving unit and determine a position of the defect.
A system for detecting a touch panel, comprising a movement device and a device for detecting the touch panel comprising a signal transceiving component that is movably arranged relative to the metal mesh, and comprises a signal generating unit and a signal receiving unit, wherein the signal generating unit and the signal receiving unit are configured to be arranged on the same side of the metal meshes in preset relative positions, and send and receive a signal through capacitive coupling with the metal mesh, respectively;
- and
- a defect detecting unit that is configured to detect whether each of a plurality of touch units in the metal mesh has a defect based on a detection signal received by the signal receiving unit and determine a position of the defect,
- wherein the movement device is configured to control the signal transceiving components to move along center lines of a row direction channel and a column direction channel of the metal mesh, and send positioning information indicating a detection position of the signal transceiving component to the defect detecting unit.
