Technology for Grade 1 LCDs

For decades, color-critical video monitoring for broadcast and post-production applications was performed on a reference (grade 1) CRT monitor, or a reference projector for cinema applications. Flat panel displays, although having clear advantages in terms of depth, longevity and insensitivity to magnetic fields, have until recently failed to produce accurate and stable pictures as required for true grade 1 monitoring. Various LCD artifacts stood in the way of accepting LCD as the next technology for color critical applications: insufficient viewing angle causing a drop in contrast, a color shift or even a color inversion; crushed dark levels and clipped highlights; over-saturated colors, skin tone errors and color cast errors; motion blurring, deinterlacing problems, jaggies, and motion judder; unstable colors and unstable brightness.
