A Wide Color Space with Six Color Space Modes
The color space of the BT-LH2550 is 102% that of the NTSC
standard, so it exceeds the EBU/SMPTE range that can be displayed
by ordinary LCDs. It accurately reproduces colors that are not easily
reproduced by conventional displays, including CRTs, to meet the
needs of both broadcasters and image production companies, and to
work in fields such as digital cinema, CG production, printing,
publishing, advertising, and research. The BT-LH2550 also offers
three new color space modes in addition to the three conventional
modes. The modes are switchable by menu bottom.

Double-Speed Drive for Blur-Less Moving Images
[BT-LH1760 only]
Moving images without any afterimage are achieved by driving at a
speed (120 Hz/100 Hz) that is twice the panel speed and inserting
a black frame of a certain level between frames. Unlike frame
creation methods, this system minimizes afterimages while
displaying images faithful to the input signal. This high-
performance, high-speed image display function is ideal for
broadcast applications.
