Problems solved by technology

However, since the display panel itself is also a source of signal generation, when a high voltage is applied to the data lines of the display panel, the data lines may be coupled with the sensing pads in the touch panel, which seriously interferes with the sensing received by the sensing pads. signal, which leads to poor sensing ability of the touch panel

Abstract

The invention discloses a touch control display device which comprises a display panel, a shading electrode layer, a touch panel, a conductive element and a flexible circuit board, wherein the display panel is covered with the shading electrode layer, and the touch panel is configured on the shading electrode layer. The touch panel comprises a baseplate, a touch control element, one or more grounding electrode and one or more metal wires; and the touch control element comprises one or more sensing electrodes, one or more transmission conducting wires and two or more connecting pads. The transmission conducting wire is electrically connected with the sensing electrode and one of the connecting pads. The metal wire is connected with the grounding electrode and the other connecting pad. The shading electrode layer is electrically connected to the metal wire or the grounding electrode of the touch panel through a conductive element. The flexible circuit board is electrically connected with the connecting pads so as to enable the sensing electrode and the metal wire to be electrically connected to the flexible circuit board.

Description

technical field [0001] The present invention relates to a display device, and in particular to a touch display device. Background technique [0002] In the daily life environment, the phenomenon of electrostatic discharge can be seen everywhere. Due to the different affinity of electrons for various objects, any two objects that are in contact and then separated will easily produce the phenomenon of charge transfer between objects, resulting in the accumulation of static electricity. Once the static electricity in the object accumulates to a certain level, when the object with static electricity touches or approaches another object with a different potential, the phenomenon of instantaneous charge transfer will occur, which is the so-called electrostatic discharge. [0003] Taking the display panel as an example, the display panel has a high possibility of being damaged by electrostatic discharge during the process of manufacturing, production, assembly, transportation, and...
