Abstract
A focus control apparatus for a display is provided. The focus control apparatus adjusts the focus of a lens through a simple manipulation of an adjusting knob which adjusts a position of a connection tube connecting an image engine and a lens of the apparatus. The focus control apparatus adjusts the focus of the lens by the backward and forward movement of the connection tube, thereby simplifying the structure of the apparatus, improving productivity, and reducing the production cost.
