PURPOSE: A method for compensating for a negative pixel is provided to apply an outputted grounding signal to an outputted touch signal, thereby compensating for a negative pixel effect. CONSTITUTION: First lines(202a~202c) are switched respectively and are related to second lines(204a~204c). A switching circuit network is combined with the first lines. The switching circuit network measures the grounding state of an entity by switching a first line which transmits a stimulation signal and another first line which transmits a capacitance signal which shows a grounding state of an entity adjacent to the circuit. A processor compensates for a touch signal by the capacitance signal. The processor calculates a compensation factor which shows the ratio of a signal which shows the grounding state to the touch signal. |
