Abstract
Official abstract text for this publication.
A touch sensing apparatus includes a touch sensor and a touch controller for sensing whether touch is present from a readout signal of the touch sensor as well as driving the touch sensor, wherein the touch sensor includes a plurality of scan channels including a plurality of first sensing electrodes arranged in a first direction in a sensing area, a plurality of readout channels including a plurality of second sensing electrodes arranged in a second direction that crosses the first direction in the sensing area, a ground routing line formed to surround the sensing area in a bezel area surrounding the sensing area, a dummy routing line formed between the ground routing line and an outermost readout channel among the plural readout channels in the bezel region, wherein a signal with the same phase as the outermost readout channel is supplied to the dummy routing line.
First claim
Opening claim text (preview).
What is claimed is: 1. A touch sensing apparatus, comprising: a plurality of readout channels arranged next to each other, each readout channel comprising at least one sensor electrode; a ground routing line arranged next to at least one outermost readout channel of the plurality of readout channels; at least one dummy routing line arranged between the ground routing line and the at least one outermost readout channel; and a touch controller configured to provide a signal th…
