How Sgi Developed The 1600sw Display-www.274300.cn

Hardware Silicon Graphics, Inc, or SGI, was founded back in 1982 and has evolved in to a household name as a producer of maker of cool looking custom graphics workstation machines which have found a huge following in Hollywood design, special effects, and CGI departments. SGI’s 1600SW flatscreen monitor is an innovative piece of machinery which was first introduced in 1998 and has more than stood the test of time – it continues to thrive. And one of the reasons for this is that it’s got an active matrix LCD, or an AMLCD (active matrix is also sometimes called TFT, or thin film transistor). As you might guess, this is the opposite of passive matrix LCD. What’s so special about AMLCD? In an liquid crystal display monitor, each pixel it contains has to be energized, and it gets energized–that is, electrically addressed–to either permit light in or prevent light from getting in (block it out). The difference between an active and a passive matrix display has to do with the way the pixels get electrically addressed. Now, the passive matrix flat panel displays contain a grid of vertical and horizontal wires, and at the intersection points on the grid there’s an LCD element–a single pixel. But AMLCD flat screen panels are more expensive, and while this puts off those who don’t kno what they’re looking for or who just don’t care that much, as with most things you get what you pay for. For you see, with these flat screens there are transistors built right into each pixel within the screen. Think that gives you far superior resolution? You bet it does. SGI’s 1600SW’s 1600×1024 screen size depends on more than 14 million transistors. There’s a transistor assigned to each and every blue, green, and red subpixel. In addition to the higher resolution, users also get higher contrast and far faster pixel response rates than do the passive matrix LCDs. The way that SGI’s 1600SW uses pixelated space to create displays is one of the core reasons why it’s so often used even today by not just Hollywood studios but also graphic designers, engineers, research scientists, and R&D departments in the manufacturing and energy industries. Silicon Graphic’s clients range from Disney to NASA and other government agencies. And, even though LCD manufacturers deliberately permit a small amount of the defect known as "stuck pixels" in order to keep them affordable (making them "perfect" is prohibitively expensive), Silicon Graphic’s 1600SW has been engineered to give graphical power users the tool they need to get the job done.
