Abstract: The invention provides a touch array substrate, a touch display, and a display device. The touch array substrate includes a driving circuit layer, a touch layer, and a sleep state voltage equalizing connecting unit which are mutually insulated. The driving circuit layer includes driving scanning lines, odd row driving data signal lines, and even row driving data signal lines. The touch layer comprises touch scanning lines, odd row touch data signal lines, and even row touch data signal lines. In a display sleep state, the sleep state voltage equalizing connecting unit enables mutual electrical connection of the odd row driving data signal lines, the even row driving data signal lines, the odd row touch data signal lines, and the even row touch data signal lines.

Abstract: A touch liquid crystal panel includes an array substrate and a color filter substrate disposed opposite, mutually insulated self-capacitance electrodes and electrode leads are disposed on the array substrate, the electrode leads are covered by a second insulating layer. A main post spacer and a sub post spacer are disposed between the array substrate and the color filter substrate. A first end of the main post spacer is connected to the color filter substrate, a second end extends towards the array substrate and opposite to a first electrode lead, a position of the first electrode lead corresponding to the second end of the main post spacer is etched to form an avoidance zone, the second end of the main post spacer is contacted with the second insulating layer in the avoidance zone. A first end of the sub post spacer is connected to the color filter substrate.

Abstract: The present disclosure relates to an array substrate of embedded touch panels. The array substrate includes a touch electrode arranged in an active area of the touch panel in a matrix, a touch sensing chip arranged outside the active area of the touch panel, a plurality of metal connecting lines arranged on a different layer with the touch electrode. The metal connecting lines connect to the touch electrode via at least one through hole, and the metal connecting line and a data line of the touch panel are insulated from each other and are overlapped. The touch electrode connects to the touch sensing chip via the metal connecting line, wherein a switch circuit is arranged between the metal connecting line and the data line. The switch circuit connects the metal connecting line and the data line in a touch phase, and the switch circuit disconnects the metal connecting line and the data line in a display phase.
