Abstract

The embodiment of the invention discloses a touch substrate and a touch device. The touch substrate comprises a thin film transistor, a transparent public electrode layer and a pixel electrode layer. The public electrode layer comprises public electrodes and touch drive electrodes, wherein the public electrodes and the drive electrodes extend in a first direction, and space between the public electrodes and the touch drive electrodes is filled with insulation dielectric; the touch substrate is further provided with touch sensing electrodes, wherein the touch sensing electrodes are at different layers from the touch drive electrodes and extend in a second direction, and the space between the public electrodes and the touch drive electrodes is covered with the touch sensing electrodes; within the display time of a frame of image, the touch drive electrodes are used for transmitting public electrode signals and touch scanning signals in a time-share mode. The touch drive electrodes and the touch sensing electrodes do not have alignment areas, the node capacitance of touch electrodes can be reduced to the maximal extent, and the touch sensitivity is improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch substrate and a touch device. Background technique [0002] At present, the display technologies that can realize wide viewing angle mainly include IPS technology (In-Plane Switch, in-plane switching technology) and ADSDS (ADvanced Super Dimension Switch, advanced super dimension field switching technology, referred to as ADS); among them, ADS technology is mainly through the same The electric field generated by the edge of the slit electrode in the plane and the electric field generated between the slit electrode layer and the plate electrode layer form a multidimensional electric field, so that all oriented liquid crystal molecules between the slit electrodes in the liquid crystal cell and directly above the electrodes can be rotated, thereby The working efficiency of the liquid crystal is improved and the light transmission efficiency is increased. Advanced ultra-dimen...
