Abstract
Official abstract text for this publication.
A capacitive touch panel and operating and fabrication methods thereof. The capacitive touch panel has a plurality of transmitter electrodes and a plurality of receiver electrodes. An electric field is formed by the receiver electrodes and the powered one of the transmitter electrodes. The changes, caused by the touch of a user, in the electric field are used in touch recognition. The receiver electrodes are all in a fork shape. For one receiver electrode, the teeth are spaced in a first distance. Note that adjacent teeth from different and adjacent electrodes are spaced apart by another distance. The second distance is greater than the first distance.
First claim
Opening claim text (preview).
What is claimed is: 1. A capacitive touch panel, comprising: a first set of electrodes, disposed to extend along a first axis of a two-dimensional coordinate; and a second set of electrodes, disposed to extend along a second axis of the two-dimensional coordinate and spaced apart from the first set of electrodes, wherein each one of the second set of electrodes contains branches which are spaced apart by a first distance, and adjacent two branches from two different and adjace…
