46 inch lcd panel fiyatlar谋 factory

The enhanced panel quality of Samsung’s UDE-B video wall (available in 46- and 55-inch sizes) elevates visual messaging and content through a seamless image and superior clarity. Featuring an ultra-narrow 3.5mm bezel-to-bezel design format (2.3mm bezel on the left and top sides and 1.2mm bezel on the right and bottom sides), which is the slimmest bezel in the video wall industry, the display creates a virtually uninterrupted viewing experience to keep audiences focused on content rather than the display itself.

When exposed to a range of environmental conditions, video wall panels can run the risk of losing image quality due to distortion and irregular color presentation. To provide consistent display clarity uninterrupted message delivery in any operational environment, Samsung’s UDE-B video wall panels undergo rigorous performance testing. Each display features a reinforced panel that deters heat, weather and other stress-inducing conditions. As a result, Samsung’s superior panel prevents screen darkening, light leakage or any related deterioration in picture quality. Plus, an anti-glare panel to ensure messages reach relevant audiences with minimal distraction by light reflection – All these enhanced panel quality allows the long term delivery of brilliant contents and the ultimate viewing experience

NEC"s 46" UN462A sets the standard for quality color reproduction in video wall environments. Direct LED backlighting and factory calibration for intensity, gamma and RGB allows for ideal panel uniformity and an easy out-of-the-box experience. This display is integrated with the proprietary SpectraView Engine, which not only allows for ultimate color control but also allows for increased color calibration capabilities including white copy, self calibration to an external sensor and manual CIE chromaticity adjustment for maximum control when color matters most. This display also includes both a DisplayPort and an HDMI Out connections for daisy chaining signals up to 4K UHD. This new generation of display received a full chassis upgrade with a 3.5mm bezel gap, faster processing times, evolved daisy chain performance, and new TileMatrixing capabilities.

One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.

Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.

On the other sheet of glass, you make an array of millions of red, green, and blue dots in a black matrix, called a color filter array (CFA).This is how you produce the colors when you shine light through it.Then you drop tiny amounts of liquid crystal material into the cells on the first sheet and glue the two sheets together.You have to align the two sheets so the colored dots sit right on top of the cells, and you can’t be off by more than a few microns in each direction anywhere on the sheet.The sandwich is next covered with special sheets of polarizing film, and the sheets are cut into individual “panels” – a term that is used to describe the subassembly that actually goes into a TV.

For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.

The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.

LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.

It obviously costs a lot to equip and run such a fab.Including all of the specialized production tools, press reports say BOE spent RMB 46 billion (US$6.95 billion). Even though you don’t see a lot of people on the floor, it takes thousands of engineers to keep the place running.

The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.
