In video projection terminology, throw is the distance between a video projector lens and the screen on which it shines. It is given as a ratio (called throw ratio), which describes the relationship between the distance to the screen and the width of the screen (assuming the image is to fill the screen fully).
A projector's throw ratio is used when installing projectors to control the size of the projected display. [1] For example, if the throw ratio is 2:1 and the projector is fourteen feet away from the screen, then the display width will be seven feet.
Two projectors mounted in a special pedestal allowing twice the brightness. ... VPH-2030 is the wide throw version of the projector for 200-inch (5,100 mm) diagonal ...
Not long ago, a 4K ultra-short-throw projector for $1,800 would have been remarkable. Now that 85-inch TVs can be had for under $2,000 and sometimes even under $1,500? Much less remarkable.
Some older LCD projectors have a more noticeable screen-door effect than first generation DLP projectors. [2] Newer DLP chip designs promise closer spacing of the mirror elements which would reduce this effect; [ citation needed ] however, some space is still required along one edge of the mirror to provide a control circuit pathway.
n November 1954, 29-year-old Sammy Davis Jr. was driving to Hollywood when a car crash left his eye mangled beyond repair. Doubting his potential as a one-eyed entertainer, the burgeoning performer sought a solution at the same venerable institution where other misfortunate starlets had gone to fill their vacant sockets: Mager & Gougelman, a family-owned business in New York City that has ...
The optimum viewing distance is affected by the horizontal angle of the camera capturing the image. One concept of an ideal viewing distance places the viewer where the horizontal angle subtended by the screen is the same as the horizontal angle captured by the camera.
DLP technology is used in DLP front projectors (standalone projection units for classrooms and business primarily), DLP rear projection television sets, and digital signs. It was also used in about 85% of digital cinema projection as of around 2011, and in additive manufacturing as a light source in some printers to cure resins into solid 3D ...
