Title:
TOUCH SCREEN FOR NARROW-BEZEL ELECTRONIC APPARATUS, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/156234
Kind Code:
A1
Abstract:
Embodiments of the present application provide a touch screen for a narrow-bezel electronic apparatus and an electronic apparatus. The touch screen comprises: an electrically conductive layer, a display module, a first circuit board, and a second circuit board. The electrically conductive layer comprises touch sensing electrodes and N first lead wires, the first circuit board comprises a touch drive integrated circuit, and the second circuit board comprises one or more traces. The touch sensing electrodes are respectively coupled to first ends of the N first lead wires. M first lead wires of the lead wires each have a second end coupled to a first end of one trace of the second circuit board. Each of the traces of the second circuit board has a second end coupled to the touch drive integrated circuit, where M is less than or equal to N. The one or more traces of the second circuit board are used to couple the second end of each of the M first lead wires to the touch drive integrated circuit. The touch screen of the embodiments of the present application reduces manufacturing difficulties and costs.
