Abstract

The invention relates to a touch substrate, a preparation method and a display device, and relates to the field of display technology. Wherein the touch substrate includes a substrate with several through holes; on the first surface of the substrate, a first electrode covering the several through holes is formed; on the second surface of the substrate opposite to the first surface, respective A plurality of second electrodes corresponding to a touch area; the second electrode at least partially surrounds the edge of the through hole at least in one place; an elastic conductor block is arranged in the through hole to form a hole in the through hole when the substrate is pressed. Electrical connection between the first transparent electrode and the second transparent electrode at both ends; the first transparent electrode is connected to the bias voltage input end; each of the plurality of second transparent electrodes is connected to the respective detection signal output end through a detection line. The invention integrates the touch sensing on the substrate, only needs to add the corresponding electrode forming process and the process of injecting the elastic conductor block into the through hole in the process of preparing the substrate to realize the touch sensing.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch substrate, a preparation method and a display device. Background technique [0002] With the continuous development of display technology, touch screen displays have been widely used in electronic devices such as mobile phones and tablet computers. When the user touches the touch screen surface of the touch screen display with a finger, the touch position is sensed by the change of the internal circuit or capacitance of the touch screen, and a response is made. [0003] Existing touch screen displays include a display module and a touch module, and the touch module and the display module are usually bonded by optical glue to form a display device with a touch function. However, the touch module of the existing touch screen display is located outside the display module, and assembly tolerances are likely to occur during assembly, which affects the accuracy of touch sensi...
