Touch sensing device having a plurality of gate drivers on array adjacent to each of a plurality of touch modules
摘要:
The present invention, in one aspect, relates to a touch sensing device. In one embodiment, the touch sensing device includes a plurality of touch modules spatially arranged in a form of a matrix having a plurality of rows and a plurality of columns, and a plurality of GOAs configured to receive a clock signal. Each GOA has an input for receiving a driving signal and an output for responsively outputting a delayed driving signal by a time interval to a respective touch module. The plurality of GOAs is spatially arranged in a form of a matrix such that each GOA is disposed adjacent to and associated with a corresponding touch module. The plurality of GOAs is electrically coupled to each other in series as a chain such that the output of any one but the last GOA in the chain is connected to the input of its immediate next GOA in the chain, so that, in response to a start signal applied to the first GOA in the chain, sensing signals from successive corresponding touch modules are sequentially detected by a plurality of sensing devices.
