Types of channel letter signs:
Front illuminated
This type is when the letters or logos have a translucent face, usually acrylic or polycarbonate that allow the light to go through it
Hallo lit (backlit)
This type is when the back of the letter is translucent and allow the light to flow to the back surface of the letter or logo
Front and back-lit
This is when the front and the back of the letter and logo are translucent and can allow the light to go through them
open-face (exposed)
This is when the face of the letter or logo is open (exposed) and the neon or LED or internal lit shape is showing
Custom illuminated
This usually depends on the design and the environment where the sign will be installed
Self-contained letters and logos
This when the return (the edge of the letters or logo) is expanded to contain the whole sign or part of it to make it one piece or more rather than individual letters or shapes
Multi-layers channel letter signs
That could be by adding a larger aluminum plate behind the letters to work as a shadow or a surface that light casts on in case of backlit or per design requirement
Shadow-like backplate channel letter signs
Back plate shaped as the letters or logo slightly larger in size to an outline effect to letters
