Term most oftenly used when referring to a flat-panel display. A flat screen implies a traditional CRT with a flat picture tube. The items that you will find here at PresentationMart are flat-panel displays, thin display screens that utilize a number of technologies including plasma and LCD (liquid crystal display). For a more indepth explanation of these
Flicker is a plug introduces flashing/flickering brightness into your clip. if you choose a low frequency (e.g. twice a second), it looks as if the active part of clip is flashing (highlighted) like a cursor. on higher frequencies, it looks like those old super-8 films when using an old projector.
Alternating is a change in the intensity of light, typically
A sampling system that consists of 2 pieces on a separate front projector (usually placed on a table or mounted on the roof) and a screen. A front-projection system beams the image onto the front side of the screen. The front projection systems can display images up to 240 inches wide or larger. The traditional, large and expensive front projectors that are
It is the speed at which the pictures are displayed. The frame rate for movies is 24 frames per second (24 fps). In regular NTSC video, the frame rate is 30 fps. The frame rate of a progressive scan format is twice as a form of interlace scanning. Example: the frame rate for DVD 480i is 30 fps (or 60 frames per second interlaced), to progressive scan DVD to
It is a complete picture, in a single film. In a video signal, a box containing all the lines of the scanned image. The speed of a box format Progressive Scan (Progressive Scan) is double that of a format of interlaced scanning (Interlace).
It is complete picture of TV consisting of two fields (field and field odd couple). In the PAL system there are 25
A relatively lightweight and ultra-TV - especially those that can be mounted on the wall. The biggest television technology revolution since color, flat-panel plasma and LCD TVs are well on their way to replacing tubes as the TV technologies of choice. You can hang flat sets on the wall, on the ceiling, or above the mantle in place of a trophy buck--
Each full picture is divided into 2 sequential fields, each of which contains half the scanning lines of the table. A field containing the odd scan lines, and the other field lines scan pairs.
The maximum luminance peak for a projector is typically along the direction of its lens's optical axis and it diminishes with a Gauss-like function orthogonal to
Portable home-theater LCD and DLP projectors both come in different "fixed" resolutions. That is, not every projector has the same resolution as every other. And a projector's fixed resolution rarely matches the exact resolution of the incoming signal. Therefore, the projector must first resize the signal's image internally, through
This feature allows you to maintain that fixed the image projected on the projector, while the user can perform any operation without this is seen by the audience. The image being projected can be made to be frozen. This function is to be used to pause a video during a presentation, etc. Users can freeze images comparing live images and captured frozen
It is the distance from the surface of the lens to the focal point or other words it is the distance between the center of a lens and the spot where the picture is beginning to focus.
The focal length of a lens determines how wide an angle the image is projected. In simple terms the larger the number of the focal length of the lens the narrower the beam.
