LOCATION DISPLACEMENT DETECTION METHOD, LOCATION DISPLACEMENT DETECTION DEVICE, AND DISPLAY DEVICE

摘要

A location displacement of an electrode of a device relative to an electrode pad of a semiconductor element is detected based on a conduction state between the electrode pad of the semiconductor element and the electrode of the device. The electrode pad of the semiconductor element is segmented into multiple portions and a first pad through a fourth pad uniformly arranged. A location displacement detector determines that no location displacement has occurred when the electrode pad of the semiconductor element is conductive to the electrode of the device, and determines that a location displacement has occurred when the electrode pad of the semiconductor element is non-conductive to the electrode of the device.
