Abstract
A display apparatus and method for controlling interference includes a signal receiving unit which receives a signal in an effective frequency band from an input device; a signal processing unit which processes a signal on the effective frequency band to output a user input signal; a display unit which displays an image based on the user input signal; and a diminishing signal generating unit which generates a diminishing signal having a waveform diminishing a noise outside the effective frequency band.
Claims20
A display apparatus, comprising:
- a signal receiving unit which receives a signal in an effective frequency band from an input device;
- and
- a diminishing signal generating unit which generates a diminishing signal which surrounds the effective frequency band and comprises a waveform diminishing a noise outside the effective frequency band,
- wherein the diminishing signal interferes with the noise generated from an inner part of the display apparatus or emanated from an outside source, and
- wherein the diminishing signal is in a frequency band that does not overlap with the effective frequency band.
