  • Color Depth (Gray Scale) of LED Displays
  • 20-06-2013
The LED display color depth, or gray scale, indicates the process depth of the colors showed by a LED display. When looking at the technical specifications of a LED display given by LED display suppliers you can always find values like "12-bit, 14-bit, 16-bit". Below part will let you know what does the Gray Scale mean in detail.

1-bit color (21 = 2 colors): often black and white

2-bit color (22 = 4 colors)

3-bit color (23 = 8 colors)

4-bit color (24 = 16 colors)

5-bit color (25 = 32 colors)

6-bit color (26 = 64 colors)

8-bit color (28 = 256 colors)

12-bit color (212 = 4096 colors)

14-bit color (214 = 16384 colors)

16-bit color (216 = 65536 colors)

 

So from above table, it's not difficult to find the color depth actually shows how many colors can be shown on the LED display. For the widely-adopted technology, the highest color depth is actually 14 bits. If adopting higher level IC and system, it won’t be any problem to realize the 16-bit color depth or gray scales. But actually the 14-bit color depth or gray scale doesnt make any big difference from 16-bit color depth for the human eyes.
