Abstract
A display driving device includes sensing lines configured to sense pixel signals of a display panel; and a voltage limiter provided for each of the sensing lines. The voltage limiter senses a voltage variation of the sensing line, and limits a voltage level of the sensing line to a reference voltage.
Claims7
A display driving device comprising:
- sensing lines configured to sense pixel signals of a display panel;
- and
- a voltage limiter corresponding to each of the sensing lines, and configured to sense a voltage variation of the sensing line and limit a voltage level of the sensing line to a reference voltage,
- the voltage limiter comprising:
- a first comparator configured to compare a voltage of the sensing line and a first reference voltage, and output a first comparison signal;
- a second comparator configured to compare the voltage of the sensing line and a second reference voltage, and output a second comparison signal;
- and
- an operator configured to output a reset signal by performing a logic function on the first comparison signal and the second comparison signal.
