Flicker free means that an image is free of flicker. A well set up 3D television should be free of any noticeable flicker. Sometimes a flicker can be noticed when batteries in the glasses are discharged. Charging them usually fixes the problem right away.

This is the compromise for having glasses that don't have batteries.
The Flicker was created in 1965.
