Abstract:
1. A touch sensing device having a touch panel, comprising: (a) a plurality of touch modules spatially arranged in the touch panel in a form of a touch module matrix having a plurality of rows and a plurality of columns; (b) a plurality of primary gate driver on array circuits (GOAs) configured to receive a first clock signal, spatially arranged in the touch panel in a form of a GOA matrix located corresponding to the touch module matrix such that each primary GOA is disposed adjacent to and associated with a respective touch module, each primary GOA having an input for receiving a first driving signal and an output for responsively outputting a delayed first driving signal by a first time interval to a respective touch module, wherein the plurality of primary GOAs in each row is electrically coupled to each other in series such that the output of any one but the last primary GOA in a corresponding row is connected to the input of its immediate next primary GOA in the corresponding row, so that, in response to a driving signal applied to the input of the first primary GOA in the corresponding row, sensing signals from successive corresponding touch modules in the corresponding row are detected by a corresponding plurality of sensing devices; (c) a plurality of secondary GOAs configured to receive a second clock signal, spatially arranged in the touch panel in the form of the GOA matrix located corresponding to the touch module matrix such that each secondary GOA is disposed adjacent to and associated with the respective touch module, each secondary GOA electrically coupled to a first primary GOA in a respective row of the plurality of primary GOAs, and having an input for receiving a second driving signal and an output for responsively outputting a delayed second driving signal by a second time interval to the first primary GOA in the respective row, wherein the plurality of secondary GOAs is electrically coupled to each other in series such that the output of any one but the last secondary GOA is connected to the input of its immediate next secondary GOA, so that, in response to a start signal applied to the input of a first secondary GOA, sensing signals from successive rows of corresponding touch modules are detected by the plurality of sensing devices in a row by row fashion.
