Touch apparatus, electronic device and preparing method

An electronic device, comprising a touch apparatus, wherein the touch apparatus comprises:

• a substrate, comprising a display region, and the display region comprising a first display region and a second display region arranged in a first direction, wherein the touch apparatus is bendable along an axis, the axis is a boundary between the first display region and the second display region, and the boundary between the first display region and the second display region is a straight line;
• a cover plate,
• a first touch sensor formed on a surface of the cover plate, and
• a second touch sensor formed on a surface of the substrate;
• wherein:
• the cover plate is attached to the substrate, and a side of the cover plate provided with the first touch sensor is arranged opposite to a side of the substrate provided with the second touch sensor;
• the first touch sensor is arranged on the side of the cover plate towards the substrate;
• the second touch sensor is arranged on the side of the substrate towards the cover plate, and the second touch sensor is arranged in a different layer from the first touch sensor;
• a projection of an edge of the first touch sensor on the substrate and a projection of an edge of the second touch sensor on the substrate overlap with each other at the axis;
• the first direction is parallel to the substrate, the first touch sensor has a first projection on the substrate in a second direction, the first projection covers the first display region, the second touch sensor has a second projection on the substrate in the second direction, the second projection covers the second display region, and the second direction is perpendicular to the substrate;
• the substrate is an OLED display panel, the first touch sensor and the second touch sensor are electrically connected to a same control chip via conductive wires arranged on the substrate, and the wires and an anode of the OLED display panel in a same conductive layer;
• a conductive member is arranged between the substrate and the cover plate, the conductive member comprises a support column and a connection layer arranged on a surface of the support column, the connection layer and a cathode of the OLED panel are in a same conductive layer and are made of a same material;
• and
• the first touch sensor is connected to the wires via the connection layer.
