Fully digitized high-quality images elude all attempts In pursuit of greater beauty Digital AccuDevice, the unique signal-processing circuit developed by NEC Digital AccuDevice generates advanced vividness using a fully digitized signal-processing circuit. LSIs packaged on the circuit are integrated into three circuits to achieve the full digital sampling of all input signals without any omissions. Furthermore, all processing steps for video input signals are fully digitized. Since there is no analog conversion process involved and original video images can be processed digitally as they are, there is no deterioration of the signal, and the high-definition progressive expression and clear resolution conversion suppress noise and produce breathtaking images. The introduction of new LSIs permit the fully digitized processing of video input signals Video input signals Converts analog signals into digital signals Converts into high progressive signals Executes resolution conversion and gamma correction Processing with digital signals Mass Area Superior Sampling Technology achieves high-definition progressive expression All input signals are displayed using progressive expression. In ordinary processing, interlaced signals are converted into progressive signals, and the sampling of interpolation lines are processed on the basis of brightness signals. With the newly developed Mass Area Superior Sampling Technology, color signals are sampled and interpolated together with the brightness signals. The new technology produces sharp expression without jagged edges or colour bleeding. Ordinary expression PlasmaSync Vivid, breathtaking colours Insatiable desire for vivid colour reproduction The highest contrast ratio in the industry at 200:1 under bright conditions PX-50XM4 and PX-42XM3 achieve the highest contrast ratio in bright conditions in the industry, as a result of efforts to pursue higher visibility under bright lights or in sunlight. Obtain vivid, sharp video images regardless of the environmental conditions of the locations. (As of July 2004) AccuCrimson reproduces accurate red colour AccuCrimson, employed in the front filter, is a technology for attenuating the orange colour included in the wavelength for red, which is particular to the plasma display. AccuCrimson clearly expresses the delicate difference between cinnabar and red colours and reproduces natural skin tones-tasks which are difficult with ordinary plasma displays. Before introducing AccuCrimson Strong Red Green Blue Weak Wavelength After introducing AccuCrimson® Strong Pure green Pure blue Pure red Weak Wavelength The CCF method, a unique NEC technology, and black stripes reproduce vivid, accurate colour With the CCF (Capsulated Colour Filter) method, each pixel is capsulated and embedded with color filters for the three primary colours (RGB); the results are that the red, blue, and green colors are reproduced more accurately. By providing black stripes on the barriers between cells, a sharp black colour is also expressed. By employing NEC's unique technology, vivid colours are reproduced and a pure white color is expressed to reduce screen deflection. CCF method and AccuCrimson Black stripe The CCF method and AccuCrimson AccuCrimson contribute to an improvement in contrast performance by reducing screen deflection Pure red light Pure green light Pure blue light External light External light External light (Isolation) Unwanted light (Isolation) Unwanted light (Isolation) Unwanted light Glass substrate Rare gas Cell Pixel Phosphor Optimized colour spectrum of phosphor The CCF improves the purity of colors by filtering the three primary colors (RGB). Removal of unwanted light The CCF removes the orange color, particular to plasma displays, emitted by neon gas. Reduced screen deflection The CCF and the black stripes reduce screen deflection to produce a high contrast ratio under bright conditions. Optimized red color The CCF suppresses the wavelength of the orange colour included in red to reproduce a pure red color. The highest capability for colour expression in the industry with 4,096 steps equivalent to 68.7 billion colours By introducing Gamma-12, rich and smooth expressions with 4,096 steps - the highest number in the industry - are achieved in the respective colours of R, G, and B to provide the industry's highest capability for color expression equivalent to 68.7 billion colours in the dark portion. The expression reproduces accurate, more faithful details. (As of July 2004) 4 kinds of gamma correction modes Mode 1 Mode 2 Mode 3 Brighter Details of the dark portion Mode 4 Darker The newly designed Scan Converter dramatically improves character readability The Scan Converter converts input signals in accordance with the resolution of the display. Since sampling accuracy for the interpolation of data has been improved by approximately 4 times, and its conversion accuracy has also been improved by approximately 4 times (compared to NEC's ordinary products), small characters can also be displayed uniformly with a dramatic improvement in readability. With the digital zooming function, enlarged characters will not bleed or become fuzzy. Ordinary expression Expression with the Scan Converter The Colour Tuning function adjusts specific colours The Colour Tuning function adjusts specific colours, such as red, blue, or green, individually without influencing the white balance. Since the white balance remains stable, specific colours can be adjusted depending on the video source or the purpose of use. For instance, deepen the blue colour of the sea or the green color of leaves. Chromaticity diagram Colour PDP of the CCF method White White The new module is employed for high brightness and low power consumption The plasma display expresses colours with the following mechanism. Certain voltage is applied to rare gas sealed on the inside and then the phosphors are irradiated with the UV rays generated at that time. In the new module, the phosphors are improved and the gas composition rate is reviewed to drastically improve its luminous efficiency. Since a new cell structure is employed where the grid barrier between the cells prevents interference from the electrical discharge, and a new electrode structure expands the effective discharge area, low power consumption, high brightness, high contrast, and a long lifetime are achieved at the same New cell structure Display electrode Black stripe Front glass substrate Cross-sectional view of the new cell structure Front glass substrate Display electrode Conductor layer Protection layer Rear glass substrate Phosphor CCF Data electrode Grid barrier Phosphor Grid barrier Data electrode Rear glass substrate 1 cell 1 cell Separation of cells with the grid barrier prevents interference from the electrical discharge and expands the discharge area. Long life panel A panel lifetime of 60,000 hours has been achieved for all models. *60,000 hour panel life is an approximate time for the display panel to reach half of it's original brightness. The panel life is based on motion video as the input source and all display settings at factory default. The time given does not imply any warranty beyond the products standard warranty. Four kinds of Colour temperature setting modes are available The colour temperature setting adjusts the tone of the white colour. Four preset modes and a professional mode for advanced adjustments are provided for setting the colour temperature according to the purpose or preference. Red is stronger Blue is stronger
