Abstract
The display device according to the present disclosure may comprise a display panel equipped with a plurality of pixels connected to data lines and sensing lines; a source drive IC configured to provide a data voltage to a pixel through the sensing line and equipped with a sensing block obtaining sensing data related to driving characteristics of the pixel using a signal input through the sensing line; a switch configured to control a connection via the sensing line between the pixel and the sensing block; and a power source configured to provide a test voltage or a test current to the sensing block, and the source drive IC may obtain calibration data for the sensing block by using the test voltage or the test current in a state that the switch disconnects the pixel and the sensing block.
