Character-cell displays are not considered APA, but they can be made pseudo-APA in one of two ways. One method makes a low resolution by defining a font that contains combinations of dark and light pixels. Tunneler on the PC does this. Another method divides the display into 8x8 pixel tiles and then turns pixels on and off in each tile. Several console games, such as Faceball 2000, Qix, and Elite do this.
