Abstract
An LCD display has a built-in audio processing device. The audio processing device receives audio signals from a piece of Audio/Video equipment and modulates the received audio signals. The modulated audio signals are further wirelessly emitted by infrared emitting diodes that are mounted in a position near the screen of the LCD display. When a user wears wireless earphones, the audio signals can be received and played by the earphones so people in the proximity of the LCD display will not be distracted by the sound.
