Tricolor LED display system with audio output

提供一种三色LED显示系统(10)，具有多个多色LED(22)，所说各LED同时用作显示器和数据通信元件工作。这些双重作用三色LED耦合到特定用途的计算系统(12)和音频信号发射器(16)，用于同时控制来自LED可视显示信号，并将音频信息调制到LED发射的可视光信号上。接收电路(24)从LED接收调制可视光信号，并解调所接收的信号，从而恢复音频信息，然后将这些信息通过音频接口呈现给系统的用户。 A tricolor LED display system (10) is provided having a plurality of multi-color LEDs (22) that operate as concurrent display and data communication elements. These dual-use tricolor LEDs are coupled to a special-purpose computer system (12) and audio signal transmitter (16) for simultaneously controlling the visible display signal from the LEDs, and for modulating audio information onto the visible light signal emitted by the LEDs. A receiver circuit (24) receives the modulated visible light signal from the LEDs and demodulates the received signal to recover the audio information, which is then presented to a user of the system through an audio interface.
