alpha channel

   Also found in: Encyclopedia, Wikipedia 0.01 sec.

alpha channel

In 24-bit colour, a channel for controlling colour information. Describing colour for a computer display requires three channels of information per pixel, one for each of the primary colours of light: red, blue, and green. A 24-bit graphics adapter with a 32-bit bus can use the remaining 8 bits to send control information for the remaining 24 bits.
