Title:
ELECTROSTATIC INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/137215
Kind Code:
A1
Abstract:
[Problem] To provide an electrostatic input device capable of high-resolution detection of an operation position, even if the number of channels is less than the number of electrodes. [Solution] First electrode sections (21, 22, 23, 24, 25, …) constituting a first electrode group (20) are conductively connected in pairs and constitute conductively connected electrode sets. Each conductively connected electrode set is connected to a detection terminal (S1, S2, S3, …). A second electrode group (30) has a first split electrode section (33) and a second split electrode section (34) and capacitance is created between each split electrode section (33, 34) and a first electrode section constituting one conductively connected electrode set.
