Electric signs lighted by long luminous gas-discharge tubes that contain rarefied neon or other gasses.
Neon tube signs are produced by the craft of bending glass tubing into shapes. A worker skilled in this craft is known as a glass bender, neon bender or tube bender. It is the wide range of colors and the ability to make a tube that can last for years if not decades without replacement, that makes this an art. A section of the glass is heated until it is malleable; then it is bent into shape and aligned to a neon sign pattern paper containing the graphics or lettering that the final product will ultimately conform to.
LED illuminant advertising media is one of the most popular electronic signs/displays that uses an array of light-emitting diodes as pixels.
LED illuminant advertising media is one of the most popular electronic signs/displays that uses an array of light-emitting diodes as pixels. Light-emitting diode (LED) technology is frequently used in signs. This technology, first used primarily at sporting events, later appeared at businesses, churches, schools, and government buildings. Brightness of LED signs can vary, leading to some municipalities in the United States banning their use due to issues such as light pollution. A cluster of red, green, and blue diodes is driven together to form a full-color pixel, usually square in shape.
Commonly used signage and still popular in these days and best suited for indoor/outdoor business application.
Commonly used signage and still popular in these days and best suited for indoor/outdoor business application. Sheets of Poly(methyl methacrylate) PMMA are commonly used in the sign industry to make flat cut out letters in thicknesses typically varying from 3 to 25 millimeters (0.1 to 1.0 in). Acrylic is also used extensively throughout the sign industry as a component of wall signs where it may be a backplate, painted on the surface or the backside, a faceplate with additional raised lettering or even photographic images printed directly to it, or a spacer to separate sign components.
