Disclosed is a display control method according to embodiments. The display control method includes: transmitting a command for sensing to a driver integrated circuit (DIC); receiving feedback data including a transfer start indicator from the DIC; generating an internal clock signal and shifting a phase of the internal clock signal; checking the transfer start indicator of the feedback data based on the phase-shifted internal clock signal; and repeating receiving the feedback data, generating the internal clock signal, and shifting the phase of the internal clock signal a predetermined number of times. A center value may be determined from among values corresponding to numbers of times that the transfer start indicator is received while repeating the reception, the generation, and the phase shift the predetermined number of times.
