On May 17th, our North American client provided an excellent visual display solution for a corporate event in California. The solution included building an HR1.5m4 main screen setup in the middle of the event site, and four DB2.6pro upright screens on both sides. The main screen applied IMD packaging technology, with a pixel pitch of only 1.5mm and an aspect ratio16:9, presenting vivid images in 4K resolution, giving a comfortable watching experience for event attendees; while the screens on either side conveyed a brilliant image quality with a 16-bit greyscale, 5000:1 contrast ratio.
