Patent number: 9778809Abstract: In a coordinate detection apparatus, a resistance-film is formed on a substrate made of an insulating material. A common electrode applies a voltage to the resistance-film, the common electrode extending along a plurality of a resistance-film removal areas formed by removing portions of the resistance-film. A voltage application part applies the voltage to the common electrode. The voltage is applied from the voltage application part to the resistance-film through the common electrode to generate a potential distribution in the resistance-film. A coordinate position of a contact position at which the resistance-film is contacted is detected by detecting a potential of the resistance-film at the contact position.Type: GrantFiled: December 7, 2015Date of Patent: October 3, 2017Assignee: FUJITSU COMPONENT LIMITEDInventors: Koichi Kondoh, Shozo Furukawa, Mitsuhiro Sekizawa, Takashi Nakajima
