A method of manufacturing a display substrate includes forming a common electrode line, a gate line, a data line and a switching element connected to the gate and data lines on an insulation substrate. A first pixel electrode and an insulation layer are sequentially formed on the insulation substrate. A first photoresist pattern having a first hole and a second hole is formed from a first photoresist layer on the insulation substrate. A first transparent electrode layer is coated on the insulation substrate. A second photoresist layer is coated on the insulation substrate. The second photoresist layer is exposed and developed to form a second photoresist pattern remaining in the first hole and the second hole. The first transparent electrode layer is patterned using the second photoresist pattern, to form a second pixel electrode.

A time difference adder included in a system-on-chip (SOC) includes a first register unit and a second register unit. The first register unit is configured to receive first and second input signals having a first time difference, and generate a first output signal in response to a first signal. The second register unit is configured to receive third and fourth input signals having a second time difference, and generate a second output signal having a third time difference with respect to the first output signal in response to the first signal. The third time difference corresponds to a sum of the first time difference and the second time difference.
