Product Description: all over the country, 40-inch 46-inch 55-inch 60-inch Samsung LCD splicing screen factory direct sales Samsung Ultra Vision commercial 55-inch seamless large-screen LCD display, seamless, high-definition technology breakthrough to board on the pinnacle of technology in the field of LCD. As the biggest highlight of the product to achieve a large-screen display narrowest border, bilateral only 5.7 millimeters, across the country, 40-inch and 46-inch 55-inch 60-inch Samsung LCD splicing screen factory direct LCD dual stitching distance is less than successful 7 mm historic breakthrough. Screen spacing is only 1/4 of the market the existing mainstream splicing products screen pitch, almost negligible, making the overall picture was more complete and smooth. 55-inch large-screen display Features: 1, high brightness compared with LCD TV and PC, DID LCD splicing screen has a higher brightness. TV or PC LCD splicing screen brightness is generally 250 ~ 300cd / ㎡ DID LCD splicing screen brightness of 700 cd / ㎡. DID LCD splicing screen, high-contrast 1200:1, even up to 10,000:1 contrast to more than double than the traditional PC or TV LCD, is generally rear projection of three times. 3, better color saturation the the ordinary CRT color saturation is only about 50%, and DID LCD can reach 80% -92% of the high color saturation, thanks for the DID products professional color calibration technology developed With this technology, in addition to stationary screen color calibration, but also dynamic screen color calibration, so as to ensure that accurate and stable output of the screen. 4, a wider viewing angle PVA (Patterned Vertical Alignment) technology that is "vertical image adjustment technology, the use of this technology, the viewing angle of up to dual 180 ° (horizontal and vertical). 5, better reliability ordinary LCD TV, PC monitor design, does not support the continuous use day and night, DID LCD splicing screen monitoring center, exhibition center design support the 7x24 hours of continuous use. 6, pure flat LCD flat panel display equipment, flat screen monitors real, completely free of curvature large screen without distortion. 7, slim narrow design DID product has a large display area at the same time, there is thin, light weight and other advantages can be easily spliced, installation. Stitching dedicated LCD Narrow design its monolithic edge of even less than 1 cm across the country 40-inch 46-inch 55-inch 60-inch Samsung LCD splicing screen factory direct such a small edge effect does not affect the entire display overall display.
