Abstract
Official abstract text for this publication.
A capacitive touch panel comprises a touch detection array having rows of first direction detection units and columns of second direction detection units, shared scan lines, independent scan lines and a driver control module. The first direction detection units are divided into a first group and a second group of rows arranged in an alternating manner. Each shared scan line is connected to one row of the first direction detection units in the first group and one column of the second direction detection units. Each independent scan line is connected to one row of the first direction detection units or one column of the second direction detection units that is not connected to the shared scan lines. The driver control module is connected to the shared scan lines and the independent scan lines to perform scanning processes to detect a touch input. A touch detection method is also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A capacitive touch panel, comprising: a touch detection array comprising: a plurality of rows of first direction detection units divided into a first group and a second group of rows of the first direction detection units, in which the rows of the first group are arranged in an alternating manner with the rows of the second group; and a plurality of columns of second direction detection units; a plurality of shared scan lines each connected to one row…
