Developing a 110-in. 4K × 2K TV

摘要

Recently, China Star Optoelectronics Technology Company (CSOT) successfully developed a 110-in. UHD (3840 × 2160) 3-D TFT-LCD TV panel. It was the world's first LCD panel to offer 4K × 2K resolution and 3-D capability. The maximum brightness of the panel is 1000 nits, achieved with less than 1100 W of power consumption via an LED backlight with local dimming. The color gamut is much larger than that of traditional LCD TV panels, with vivid primary colors due to the use of LED backlighting. The static dark-ambient contrast of the panel is greater than 4000:1. The panel's 3-D display technology uses 120-Hz shutter-glasses technology, and the large size particularly enhances viewer enjoyment of 3-D movies and games. The goal for making this 110-in. panel was to provide a powerful sense of immersion and "reality" for the viewer. One of the most important enabling aspects for this capability is the visual angle. Studies have shown that a larger visual angle will provide a more immersive experience.
