IN-CELL MUTUAL-CAPACITIVE TOUCH PANEL AND TRACE LAYOUT THEREOF
First Claim
1. An in-cell mutual-capacitive touch panel, comprising:
- a plurality of pixels, a laminated structure of each pixel comprising;
a substrate;
a thin-film transistor layer disposed above the substrate, a first conductive layer and a second conductive layer being integrated in the thin-film transistor layer, wherein the first conductive layer, a source electrode, and a drain electrode are formed simultaneously, and the first conductive layer is only disposed out of an active area of the in-cell mutual-capacitive touch panel, and the second conductive layer is connected with a transparent conductive layer coupled to a common voltage;
a liquid crystal layer, disposed above the thin-film transistor layer;
a color filtering layer, disposed above the liquid crystal layer; and
a glass layer, disposed above the color filtering layer;
wherein horizontal traces of first direction touch electrode and horizontal traces of MFL electrode are disposed at both an upper-side and a lower-side out of the active area of the in-cell mutual-capacitive touch panel respectively, and the horizontal traces of MFL electrode are closer to the active area of the in-cell mutual-capacitive touch panel than the horizontal traces of first direction touch electrode;
at least one driving IC is disposed out of the active area of the in-cell mutual-capacitive touch panel.

Abstract
An in-cell mutual-capacitive touch panel and its trace layout are disclosed. Horizontal traces of first direction touch electrode and horizontal traces of MFL electrode are disposed at both upper-side and lower-side out of an active area of in-cell mutual-capacitive touch panel respectively. The horizontal traces of MFL electrode are closer to the active area of in-cell mutual-capacitive touch panel than the horizontal traces of first direction touch electrode to reduce the additional coupling between the traces and electrodes. At least one trace is disposed at right-side and left-side out of an active area of in-cell mutual-capacitive touch panel to reduce entire RC loading of the in-cell mutual-capacitive touch panel.
