Abstract: An electronic device includes a processor, a touch sensor, and a touch controller including a register. The processor writes, into the register, data associated with a partial area of the touch sensor specified to sense an effective touch. When the effective touch is sensed in the partial area of the touch sensor, the touch controller writes data associated with the effective touch into the register, and the processor reads the data associated with the effective touch from the register when the data associated with the effective touch is written in the register.

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.
