Abstract
An in-cell touch display system, an in-cell touch panel and its trace layout are disclosed. The in-cell touch panel includes a plurality of pixels. Each pixel has a laminated structure bottom-up including a substrate, a TFT layer, a first dielectric layer, a first conductive layer, a second dielectric layer, a second conductive layer, a liquid crystal layer, a color filter layer, and a glass layer. The first conductive layer or the second conductive layer is a part of a bridge structure. The bridge structure is disposed closed to a side near the TFT layer or near the liquid crystal layer.
