A phase current prediction method is disclosed. The phase current prediction method predicts current representative of a PWM period using a motor model which receives current measured through a single current sensor as an input, instead of the measured current, and determines the predicted current to be phase current.

Method to predict phase current

An apparatus and method to inspect a display panel that can correctly detect a defect of the display panel itself. In the method of inspecting the display panel, a first image is captured from the display panel in a state in which no pattern is applied to the display panel. Light is then irradiated on the display panel in a state in which a pattern is applied to the display panel, and a second image is captured from the display panel. The first image can be compared with the second image, and a determination can be made as to whether or not a defect of the display panel is present.
