single color vs full color LED

Single-color and full-color LED displays serve different purposes across various application scenarios with significant differences in cost and capability. Single-color displays, also known as monochrome, use LEDs of one color, typically red, amber, green, or white, to show text and simple graphics. These displays are highly cost-effective, starting at 200 to 500 dollars per square meter, and are widely used for pharmacy signs, gas station price boards, factory production monitors, and scrolling message boards. Full-color displays combine red, green, and blue LEDs to produce over 16 million colors, enabling video playback, detailed graphics, and photographic image display. Full-color LED displays range from 800 to 5000 dollars per square meter depending on pixel pitch and quality level. Dual-color displays using red and green LEDs represent a middle ground, capable of producing red, green, and amber combinations at lower cost than full color.
