LCD Samsung 40-inch 46-inch 55-inch LCD splicing screen, monitor, advertising player, touch one machine, factory sales, quality assurance, parameters, pictures, how much money to ask me a high brightness compared to the TV and PC LCD DID LCD with higher brightness. TV or PC LCD brightness to only 250 ~ 300cd / ㎡ (≤ 20.1 ") and 400 ~ 500 cd / ㎡ (≥ 26), DID LCD brightness can reach 700 ~ 2000cd / m 2, high-contrast DID LCD 1200:1 to 7000:1 contrast, more than twice than the traditional PC or TV LCD, is generally rear projection three times. Better color saturation Fourth, the 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 more than double 178 ° (horizontal and vertical). Of course, the use of PVA technical quality is also more stable. Better reliability ordinary LCD TV, PC monitor design, does not support the continuous use day and night; DID LCD monitor the advertising machine design, and support the night of continuous use in public places and harsh environments. The ordinary TV LCD civil design, DID LCD screen close to the industry-standard design, with higher reliability. Sixth, longer life of ordinary NB, the life of the backlight of the LCD screen of the PC and TV use 30000-50000 hours, DID LCD LCD backlight life can reach more than 80,000 hours, This ensures that each piece LCD mosaic wall curtain wall and to ensure that the service life of not less than 80,000 hours after prolonged use, brightness, contrast and color consistency. Thin narrow design DID LCD has a large display area at the same time, there is thin, light weight and other advantages, easy splicing, installation. The border of the second generation of products currently marketed in 11mm or so, once the mass production of the third generation of products more below 3.7mm. Grand mosaic picture of the big screen, and a strong visual impact, has a very good show, presentations, advertising, publicity effect. 46-inch LCD splicing screen, with its thickness thin, light weight and easy to install, not restricted by space characteristics, application areas are widely used in: electricity production control centers, military command and control centers, urban management, emergency command center, traffic management, command center industrial process control display systems, radio and television shows, and monitoring systems, shopping malls, hotels, communications and information systems, financial and securities information display system, government, corporate multimedia video conferencing system, mining safety production monitoring system, the command system of urban environmental monitoring, fire meteorology, maritime flood control command system, airport, subway flights, baggage, security and surveillance systems, theater, media advertising, exhibition display systems, store brand image display system, concerts. While the former two continuous improvement in technology, but in the HD trend, there are still difficult to avoid the challenge. DLP splicing products have the advantage of the characteristics of the large size of the single-screen, and the patchwork of small, but there are also low color saturation, brightness uniformity, excessive power consumption, space and other defects, and the larger the size of its shortcomings exposed the more, by its own limited display principle, mainly rely on splicing processors of image processing functions to compensate for defects in response HD. Although dynamic PDP splicing products show excellent results, but the presence of a static display easy sunburn screen, easy to produce blur, brightness attenuation, short service life and maintenance cost of defects, a chip deal with HD slightly behind the LCD Video Wall products.
