The UVP-3X57 series is a 3.0 inch (76.2mm) height 5X7 dot matrix display. Single color displays have the choices of three bright colors - AlGaAs red/green/red orange. Multicolor displays are applicable to two colors: green and red orange. All devices have a gray face and white dot. The AlGaAs red LED chips are made from AlGaAs on a non-transparent GaAs substrate. The green LED chips are made from GaP on a transparent GaP substrate. The red orange LED chips are made from GaAsP on a transparent GaP substrate.
The UVP-3X57 Series is a 3.0‑inch (76.2 mm) high 5×7 dot matrix LED display. It is offered in single‑color versions (AlGaAs red, green, red‑orange) and multicolor versions (green and red‑orange), with a gray face and white dot.
Key specifications include a wide viewing angle, low power consumption, and detailed electrical/optical characteristics such as forward voltage ranges, luminous intensity, and maximum power dissipation per dot. The document also lists the pin‑out diagram and absolute maximum ratings for each LED color.
