How Does LPD Compare?
If LPDs are anything like other laser displays currently available (such as Mitsubishi’s LaserVue TVs), we can expect a level of picture quality not yet matched by other tech. The color gamut (the range of color that a screen can display) on laser TVs is roughly twice that of LCDs (though Sharp’s new QuadPixel technology may greatly improve matters for LCDs). This capability may actually prove to be a problem since most video content is currently made to fit the narrower color gamut and older media (DVDs for instance). This content has to be adjusted to work with the wider color gamut, but the methods for doing so may result in some serious color issues on laser displays. Prysm has not yet commented on whether LPD displays will be susceptible to this drawback. LPD technology has a few things in common with SED (Surface-Surface-conduction electron-emitter display) technology, another emerging display type. In a sense, an SED display is a more advanced, flat-panel version of the CRT. SED
