Abstract
Provided are a source driver integrated circuit (IC) according to the present disclosure including a first buffer in which first sensing data transmitted from a first source driver IC is stored, a sensing data generation circuit configured to sense a characteristic of a driving element included in each pixel and generate second sensing data, a second buffer in which the second sensing data is stored, a control circuit configured to generate a selection signal in response to an operation command, and a selector configured to transmit one of the first sensing data stored in the first buffer and the second sensing data stored in the second buffer to a second source driver IC in response to the selection signal.
