Electrode of self-capacitive touch panel utilizing serpentine trace to increase resistance
First Claim
Patent Images
1. A flat electrode of a single layer self-capacitive touch panel, coupled to a control circuit of the self-capacitive touch panel, the flat electrode comprising:
- a main portion;
a first serpentine portion, coupled to the main portion and coplanar with the main portion, comprising a serpentine trace; and
a second serpentine portion, directly connected to the main portion while not directly connected to the first serpentine portion,wherein the first serpentine portion increases a resistance of the electrode corresponding to the control circuit through the serpentine trace.

Abstract
An electrode of a self-capacitive touch panel is provided. The electrode, coupled to a control circuit of the self-capacitive touch panel via a conducting wire, includes: a serpentine portion, having a first side; a main portion, having a second side; and a connecting portion, connected to the first side and the second side to connect the serpentine portion and the main portion. A length of the connecting portion is smaller than a length of the first side and a length of the second side.
