Abstract
A touch substrate and a display device, comprising a plurality of first electrodes for touch control, a plurality of first switching units and a control unit for controlling the first switching units; any two adjacent the first electrodes are connected through one of the first switching units and each of the first electrodes is connected with the control unit. The touch substrate can avoid the problem that charges tend to accumulate on touch driving electrodes and/or touch sensing electrodes during a touch process and cannot be released well in a display phase.
