Touch display module, and manufacturing method thereof and display device

Abstract

The embodiment of the invention discloses a touch display module, and a manufacturing method thereof and a display device. In one specific implementation mode, the touch display module comprises a display substrate and a touch unit, the touch unit comprises a conductive bridge layer, an insulating layer, an electrode layer and a touch signal line, the electrode layer comprises m first electrode rows in the first direction and n second electrode columns in the second direction, the conductive bridge layer comprises a plurality of conductive bridges arranged in a display area, the first electrodes of each first electrode row are electrically connected on the electrode layer, the adjacent second electrodes are electrically connected with the same conductive bridge through the first via holes, the touch signal line comprises n first wires which are arranged on the same layer with the conductive bridges and correspond to the second electrode columns, the first wires are arranged in the display area, and the first wires are electrically connected with the corresponding second electrode columns through the second via holes. According to the embodiment, the first wires are arranged in the display area and are arranged on the same layer as the conductive bridges, so that short circuit and open circuit of the first wires can be avoided, and a frame is reduced.

Description

technical field [0001] The invention relates to the field of touch display. More specifically, it relates to a touch display module, a manufacturing method thereof, and a display device. Background technique [0002] At present, MLOC (Multiple Layer On Cell, multi-layer integrated integrated touch) technology is to make vertical (or horizontal) excitation signal emitting electrodes on LTPS, TFT-LCD and other display modules, and horizontal (or vertical) The touch signal receiving electrodes are connected to the touch drive IC through wires, and the touch position is detected by detecting the change of the coupling capacitance between the vertical electrodes and the horizontal electrodes. FMLOC (Flexible Multiple Layer On Cell, flexible multi-layer integrated integrated touch) is to apply MLOC technology to a flexible display substrate to form a flexible touch substrate. However, regardless of MLOC or FMLOC technology, the touch signal lines are routed from the non-display ...

AI Technical Summary

Problems solved by technology

However, regardless of MLOC or FMLOC technology, the touch signal lines are routed from the non-display area outside the display area. The limited space is densely routed, and there are problems of short circuit and open circuit of the signal line, and it is difficult to achieve a narrow frame.
