It is an unfortunate fact, that there are many people out there who are ready to throw accusations around based on absolutely no research whatsoever. From time to time, we have been accused of sending fake, or cheap copies (usually from China), of original screens out.
The fact is pretty much all screens are made in China, or thereabouts.
To produce a piece of hardware as complex as a flat screen, you need a very serious setup. The facilities that these devices are produced in are clean room environments. This means they are completely dust free. Workers are usually kitted out, like astronauts, in protective white suits and head gear, to ensure that no contamination can enter the complex layers of glass and reflectors that are assembled to produce the screen.
Obviously there is a huge cost to starting up a production of LCD screens, and for this reason there are less than 10 companies that produce LCD screens, and they are all big players.
For example, LG recently opened a new plant in China costing 4 billion dollars to open, and occupying 330,000 square metres of space!
So as you can see, the possibility of a company producing knock-off copies of real screens is non-existent. Unless you have 4 billion pounds sitting in your back pocket and a clean room environment occupying several hundred thousand cubic metres, you can forget LCD production.
The reality of the situation however, doesn't dissuade some people, from throwing wild accusations around, about fake or knock off copies of screens, based on absolutely no research whatsoever.
"The screen you sent me has a different part code to the original one"
- The reason for this is that LCD producers are constantly producing new part numbers for their products. They do this to keep their industry moving and their money rolling in. Models they produce are almost identical to each other, yet they keep producing every quarter of a year, a bunch of new model numbers.
Even if your laptop is only 6 months old, it would have been manufactured more than a year ago, and probably the screen inside it is 2 years old. For this reason we will often send you a newer part code, which could be from a different manufacturer. This is perfectly normal and the only way we can provide a service to you.
This is in fact how the original computer manufacturer works as well, as laptops or tablets purchased at different times, will have different brands of screen fitted inside them. This is a good example from a Lenovo brand machine.
a) "The screen you have sent me has some letters and/or numbers printed on the glass"
- or -
b) "The screen you have sent me has a much worse picture quality than the original"
We all know how difficult it is to print on non-paper objects, such as a T-Shirt for example. So imagine the difficulty in trying to run a piece of glass through a printer. It would of course require specialised equipment. So then the question becomes, why would an LCD producer invest in specialised equipment to print a code on the screen glass? And why would this have anything to do with the screen being a cheap knock off copy?
Of course, there are some people who seem to be completely devoid of logic and believe that this has happened accidentally due to cheap production methods.
What is actually happening here is that the protective film over the glass has not been removed. Often the LCD producer will kindly shrink-wrap a protective plastic film over the glass so that the screen does not get soiled with finger-marks during fitting. Once fitted this protective film can simply be peeled off.
The usual reaction to this we receive is disbelief, and the assertion that there is definitely no film to peel off the glass. We can tell you with 100% assurance that if you are seeing alphanumeric symbols printed on the glass, seemingly permanent, and visible also when the machine is powered down, you definitely need to remove the protective film!
