Abstract
An inspection method for a touch panel control substrate, with which inspection for mounting failure is able to be simply executed, is provided. On the basis of a response that is obtained, in response to a drive signal supplied to a first drive line terminal (101E), in a different drive line terminal (102E, 103E), an electrical connection state between the first drive line terminal (101E) and the drive line terminal (102E, 103E) is detected.

An inspection method for a touch panel control substrate including a touch panel controller that supplies, via a connector, a drive signal to a plurality of signal lines provided in a touch panel main body, comprising
- a supplying step of supplying the drive signal to a plurality of connection terminals each of which is electrically connected to each of the signal lines via the connector, and
- a detecting step of detecting, on the basis of each response obtained, in response to the drive signal supplied to a connection terminal among the connection terminals, in connection terminals other than the connection terminal, an electrical connection state between the connection terminal and each of the other connection terminals.
An inspection method for a touch panel control substrate including a touch panel controller that supplies, via a connector, a drive signal to a plurality of signal lines provided in a touch panel main body, comprising
- a supplying step of supplying the drive signal to a connection terminal that is electrically connected to the signal lines via the connector, and
- a detecting step of measuring an electrostatic capacitance value of the connection terminal to which the drive signal is supplied and detecting, on the basis of the electrostatic capacitance value, an electrical connection state between the connection terminal and each of other connection terminals.
A touch panel controller that supplies, via a connector, a drive signal to a plurality of signal lines provided in a touch panel main body, comprising
- a plurality of connection terminals each of which is electrically connected to each of the signal lines via the connector,
- a drive circuit that supplies the drive signal to the connection terminals, and
- a detection unit that detects, on the basis of each response obtained, in response to the drive signal supplied to a connection terminal among the connection terminals, in connection terminals other than the connection terminal, an electrical connection state between the connection terminal and each of the other connection terminals.
