“…Recently, an LCD panel of 2k × 4k pixels for projection display was introduced to produce a display with 2k × 4k pixels, 4 and made it possible to realize a 4k × 8k pixel image. The development of a 2k × 3k projector has been reported, 5 but it is a big challenge to develop a 4k × 8k video system. Table 1 shows the specifications of the 4k × 8k video system, compared with those of HDTV.…”

Abstract— An ultrahigh‐definition display system quadrupling the horizontal and vertical resolution of HDTV has been developed. In order to obtain the ultrahigh definition, four LCD panels (red, green 1, green 2, and blue) are combined using the spatial pixel‐offset method. Therefore, only green images have an ultrahigh resolution of 4096 × 7680 pixels, while red and blue images have 2048 × 3840 pixels. The ultrahigh resolution was confirmed by subjective assessment testing. The scores of the test have the same tendencies as the SQRI values. The necessary accuracy of the convergence correction is calculated to be within 0.3 pixels by the modified s‐CIELAB method.
