The CCs were hybrid sets and the CCII were 100% solid state...It had nothing to do with screen size as both were available in 23V and 25V CRT models. CC was IIRC originally Zenith's trade name for the Black Matrix CRT's they started using around the time they came up with the name.
And in case your wondering what black matrix is, it is the process of applying a grid of black non-transparent material to the face of the tube such that light can only be emitted from the individual phosphor dots but not the area in between. It improves contrast, sharpness, and to an extent convergence IIRC.
