Abstract
Methods of operating a display driver integrated circuit (IC) are provided. A method of operating a display driver IC may include generating a first clock signal, and calculating a frequency of the first clock signal using a second clock signal. Moreover, the method may include generating an adjustment signal using the frequency of the first clock signal and a target frequency, and adjusting the frequency of the first clock signal using the adjustment signal. Related display driver ICs and portable electronic devices are also provided.
