    Abstract: A display device includes a driving controller, a display panel, and an emission driver. The driving controller generates a second clock signal having second pulses in response to a first clock signal having first pulses from an external device. The display panel includes pixels. The emission driver generates an emission signal having third pulses in response to the second clock signal and applies the emission signal to the pixels. The driving controller compares a number of the first pulses and a number of the second pulses, with a first reference value, and a second reference value, and sets a compensation value of the number of the second pulses, and the driving controller compensates for the second clock signal by adjusting the number of the second pulses existing in one horizontal time based on the compensation value in a vertical blank period of the frame period.

    Abstract: An analog-to-digital converter includes a successive approximation converter, a voltage comparator, and a controller. The successive approximation converter receives an analog input voltage and a first reference voltage, determines the level of a voltage of a first node as a negative level of the analog input voltage, and using a successive approximation method determines an output logic value corresponding to one bit of the N-bit output digital code at every one successive approximation cycle while adjusting the level of the voltage of the first node based on a level of the first reference voltage. The voltage comparator compares the level of the voltage of the first node with a level of a second reference voltage to generate a comparison logic value. When the output logic value or the comparison logic value satisfies a condition, the controller terminates conversion and determines the N-bit output digital code.

    Abstract: A host processor includes a high-speed driver which generates first high-speed data, a coupling circuit which receives the first high-speed data from the high-speed driver, and removes a direct-current (“DC”) component of the first high-speed data to generate second high-speed data, a low-power driver which generates low-power data, and a passive switch which receives the second high-speed data from the coupling circuit, receives the low-power data from the low-power driver, and selectively outputs the second high-speed data or the low-power data to a display apparatus.
