Plasma

Test Procedure

After a warm-up period, a series of primary color and white test pattern windows was displayed on each plasma TV and measured with a color analyzer to determine the values for each color displayed. The analyzer software then compared the resulting color gamut for each plasma TV with the standard REC-709 HDTV color gamut and SMPTE-C color gamuts. Note that each plasma TV’s “standard” or “normal” setting was used for these tests. Where color temperature was selectable, the “middle” settings were chosen. No adjustments were made to RGB drive/contrast or gain/brightness; only factory picture settings were used.

Results and Conclusions

At least three of the test plasma TVs were able to achieve better than 75% of the REC-709 HDTV color gamut, with one TV exceeding 80%. This performance is equivalent to a typical CRT TV. The remaining two sets were able to achieve nearly 70% of the REC-709 HDTV color gamut.

Consumer Perspective

The red, green, and blue phosphors used in plasma TVs provide the same rich, saturated colors and wide color gamuts found in CRT TVs and closely match the standards for standard definition and high definition television.
