Be more specific, that is, DLP projection technology is the application of a digital micromirror chip (DMD) to do the essential components in order to achieve digital optical processing. The principle is that a light source by an integrator (Integrator), uniform light, the three primary colors through a color wheel (Color Wheel), splits the light into R, G, B three-color, and then imaged by the lens color DMD on. Synchronous signal method, the rotation of the lens of the digital electrical signal, the continuous light into gray scale, with the R, G, B three colors and the color shown, and finally through the lens projection imaging. DLP relative to the other two advantages in its patchwork stitching small, simple operation and maintenance. But its shortcomings are obvious: for example, the volume of excess weight, the key technical indicators are far less than LCD and plasma, its biggest flaw is the high operating costs: long uninterrupted work and DLP rear projection bulb will speed up the aging rate , Rear Lamp only a few thousand hours of life, if you run 24 hours a day, a few months will need to replace the projection bulb, giving users no small operational expenses. As a global industry leader in display technology, SAMSUNG has been dedicated to meeting our customers' growing technology needs of indoor full color LED large screen, and this year launched a comprehensive narrow seam stitching unit of only 6.7mm. Main features narrow stitching unit is as follows: 1. Using the Samsung DID panel original DID (Digital Information Display) panel technology has become the focus of attention in the display industry. DID panel is a revolutionary breakthrough in ultra-high brightness, high contrast, ultra-durable and ultra-narrow application, solves the LCD used in public displays and digital signage technology barriers. Generally full color outdoor LED large screen, TV or computer used by the brightness of the LCD screen is only 250 ~ 300cd / m2 Auditorium large-screen system equipment, using DID panel LCD screen brightness and up to 1500 cd / m2, contrast ratio up to 10,000: 1 than traditional LCD computer or TV to more than double, is three times the normal projection. Therefore, the use of professional DID panel LCD monitor even in bright light outdoors is also clearly visible. Currently the big screen, Samsung's professional display solutions are mostly based on the extension of the application of the technology. 2. DNleTM Digital Natural Image Engine With a positive development and 30 years of experience, Samsung finally got to create a vivid picture, exquisite detail and high contrast natural effects proprietary technology - DNleTM, which has the following characteristics: the venue LED large screen display large screen display system provided by Wuhan Wuhan Engineering Co., Ltd. Jiuhua video. Jiuhua Video Engineering Co., Ltd., Wuhan (www.jowa-tech.com) strong, credible, in Wuhan, Hubei control and adjustment equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improve Wuhan Jiuhua innovative ideas will lead into the brilliant video and you work for a better future!
