As the active matrix LCD industry matures and develops, larger LCD panels will become available. This will result in the ability to display the same quality image with fewer modules as well as higher quality images with the same number of modules. These systems are an arrangement of video monitors usually in but not limited to a square array which is capable of displaying a reconstituted television image. Dedicated electronics are used which have been designed to 'split' the video image and to distribute those portions to the appropriate video monitors to recreate the original image on a larger scale. To accomplish this, the incoming analog signal is converted to a digital signal by an AID converter before any magnification takes place.
Magnification is handled on a pixel by pixel basis.
The horizontal dimension of the picture is expanded by outputting the same pixel values a number of times, the number of repeats being governed by the magnification requirement. The vertical dimension is similarly expanded. The resulting signal is then converted back to an analog signal and transmitted to the video monitor. These systems are usually capable of manipulating multiple video signals and displaying those images simultaneously on the wall of monitors. They can also be computer controlled to sequence and control the various complex visual effects and displays.
