Abstract
A novel correction method of a display apparatus is provided. One embodiment of the present invention is a correction method of a display apparatus. The correction method includes processing in which a voltage correcting a threshold voltage of the transistor is obtained and the voltage is held in the capacitor; processing in which current flowing through the pixel is measured and a second signal based on the current is generated in the first circuit; processing in which the first signal correcting image data using the second signal is generated in the second circuit; and processing in which the first signal is supplied to the pixel.
