Problems solved by technology

[0011] However, in the structure of Patent Document 1, since the first electrode surface 921S and the second electrode surface 922S are formed over the entire surface of the electrode, the space between the first electrode surface 921S and the ground, and between the second electrode surface 922S and the ground The base capacitance between the ground wires becomes larger
Therefore, there is such a problem that when a predetermined voltage is applied between the first electrode 921 and the second electrode 922, it takes time to apply to the base capacitance, and the voltage of the adjacent first electrode surface 921S and second electrode surface 922S is detected. The response speed required for electrostatic capacitance changes becomes slower
In addition, if the capacitance at the time of detection is large, there is a problem that the power consumption increases corresponding to this part.

Description

technical field [0001] The present invention relates to a coordinate input device having a contact surface touched by an operator's fingertip or the like, and detecting the contact position of the fingertip or the like on the contact surface. Background technique [0002] In recent years, notebook-type personal computers (notebook PCs), mobile phones, and portable terminals have been widely spread. In the field of ordinary computers, the mouse has been widely used as a device for moving the cursor on the display screen, but in the fields where mobility is important, a contact surface that is touched by the operator's fingertips is often used to detect fingertips. A coordinate input device for the contact position of the contact surface. Coordinate input devices are often used in input touch panels of personal computers and the like, and are also applied to touch panels of mobile devices and various terminals by using transparent substrates and transparent electrodes.
