Throw distance is the distance from the lens of the projector to the center of the screen surface. It is expressed as a range to indicate the minimum and maximum distance in feet that the projector should be from its projection surface.
The projector and the screen have influence on each other. Throw distance refers to the distance between the projector and
TFT Active Matrix:
A thin-film transistor (TFT) panel is an active matrix display containing a microscopic thin-film transistor in the corner of each pixel. These transistors are formed by an etching process very similar to that used to fabricate semiconductors. Active matrix panels are better suited to the handling of high-quality data and video than
