[4][5][6] LPD uses a set of movable mirrors to direct several beams of light from several ultra-violet lasers onto a screen made of a plastic-glass hybrid material coated with color phosphor stripes.
The absence of x-ray risk in LPD devices also eliminates the need for the safety circuits required in CRT monitors to shut down the display if it malfunctions so as to emit increased and unsafe levels of x-rays (which can happen if the high voltage applied to the tube increases beyond the design limit of the display).
Another competitor, plasma display technology, consists of small cells of ionized gases that emit light–a process that requires a relatively large amount of power.
The TD2, building block of a video wall, does not suffer the problem of low brightness, contains no toxic component, has no consumables, and generates little heat.
[6] According to Prysm, the LPD technology has other advantages including great black levels, a wide 180-degree viewing angle, a 65,000-hour panel life with no burn-in issues, completely recyclable components, and their production process is mercury free.
