We hear this question quite often. What are the differences between LED, LCD, and VFD displays on digital weight indicators? Light Emitting Diode (LED) and Vacuum Fluorescent Display (VFD) display types are recommended for indoor applications, identifiable by digits that light up over a dark background. Exceptions like the Laserlight series remote displays (an LED type display) are designed for viewing outdoors. For most applications that are in sunlight generally the ideal choice is a Liquid Crystal Display (LCD), which is identifiable by black digits over a gray (or backlit) background.
