Problems solved by technology

In this way, the scanning signal of the touch function and the driving signal of the liquid crystal display panel will interfere with each other (coupling), which will lead to signal errors of the display function and the touch function.
In addition, when the capacitive touch electrodes are embedded in the position b, the liquid crystal display panel will generate larger parasitic capacitance due to the closer distance between the touch electrodes and the electrode film 105 , thus causing more serious signal interference.

Abstract

A display panel comprises a first substrate, a second substrate and a display media; wherein, the display media is positioned between the first substrate and second substrate. The first substrate is provided with a pixel array. The second substrate includes a plurality of first contact control electrodes arranged along a first direction and a plurality of second contact control electrodes arranged along a second direction. Each of the first contact control electrodes is formed by staggered arranging a plurality of first upper layer contact control electrode patterns and a plurality of first lower layer shield electrode patterns, and each of the first upper layer contact control electrode patterns is electrically connected with the coadjacent first upper layer contact control electrode pattern. Each of the second contact control electrodes is formed by staggered arranging a plurality of second upper layer contact control electrode patterns and a plurality of second lower layer shield electrode patterns, and each of the second upper layer contact control electrode patterns is electrically connected with the coadjacent second upper layer contact control electrode pattern.

Description

【Technical field】 [0001] The present invention relates to a touch electrode layer and a display panel, and in particular to a touch electrode layer capable of reducing the parasitic capacitance between the touch electrode layer and the electrode layer in the display panel, and a touch electrode layer with the touch control electrode layer. The electrode layer of the display panel. 【Background technique】 [0002] Generally, existing touch display panels can be roughly classified into capacitive, resistive, and photosensitive types based on the design principle of the touch function. According to the structural classification of the touch function, it can be divided into two types: external sticker type and built-in type. Capacitive touch display panels have become a mainstream new development trend in the market due to their higher aperture ratio and better signal-to-noise ratio. The thickness of the in-cell touch display panel is thinner than that of the external touch dis...
