Evaluation of the Pioneer PDP-502MX 4 x 3 Aspect Ratio, 50 Inch Diagonal Color Plasma Display Panel
Abstract
NIDL evaluated the thin, large screen, flat panel Pioneer 50 inch plasma display panel (PDP) to determine its usefulness to the display of images that are of interest to imagery analysts and GI specialists, As NIDL's ratings show, the Pioneer PDP-502MX is not going to be useful as the primary imagery analysis display on an IEC workstation, It fails many of the IEC requirements so we rate it "F" for IEC workstation monoscopic and stereo applications, Rather, its usefulness comes from its large, 50 inch diagonal size and its high pixel count for a PDP, up to 1280 x 768 pixels in the 16:9 and 1024 x 768 pixels in the 4:3 format, that could make it appropriate for group conference discussions, The Pioneer PDP-502MX has a relatively good gray scale capability; it can display 245 of 256 differences in input levels for a 7,94 bit depth, Its linearity surpasses that we have measured for CRT monitors, and comes about because of its precisely formed pixel structure, This pixel structure, like in LCD monitors, can have several non- operating pixels, It has a very high (exceeds 60% over the entire screen) and a very uniform 1-pixel-on/1-pixel-off contrast modulation for both the horizontal and vertical directions, The PDP can have a maximum luminance up to 40 fL for a small patch of white, and a minimum luminance of 0.2 fL For full screen white, its luminance is 18 fL, limited by internal circuitry to minimize panel heat generation and its luminance is more uniform than a CRT monitor, The reflectivity and the viewing angle are about the same as for a CRT monitor, It has a capability to do stereo imaging at 43 Hz per eye, which is on the borderline of visible flicker, and its dynamic range in stereo is good, The extinction ratio is poor, and is probably limited by the long persistence of the green phosphor, Most who have seen the Pioneer PDP-502MX would love to have one, at least for football games, The price is about $18,000.
