Notebook display codes

I've come across a weird situation. There's a *matte* display used in HP and Fujitsu Amilo notebooks which has the code SEC3245 and matches to Samsung LTN154X3-L01 (see this and this - search for sec3245). A *glossy* display used in MSI notebooks has the code SEC3345 that also matches to Samsung LTN154X3-L01 (see this). How is this possible? How can a matte and a glossy display match to the same manufacturer and model? All these informations are reported by Lavasys Everest - I know that all it does is reporting what's written in the Windows registry, so it can't be wrong.

There's also another glossy display used in Toshiba and Lenovo notebooks that has the code SEC3633 which matches to LTN154X3-L06 (see this and this).

So, what's happening? Is there a mistake somewhere, or is the glossy display a modified matte one (or the other way around)? Shouldn't they be made using different technologies? Do the specs on Samsung's site really apply to all these displays?

 

I believe that the SEC stands for Samsung Electronics Corporation although I have seen Seiko Epson Corporation as another interpretation. Samsung is one of the top manufacturers of LCD panels.

My Samsung X60 plus (15.4" 1680 x 1050) is SEC3346 and my Q35 (12.1" 1280 x 800) is SEC4141. Both these are glossy.

It is plausible that the basic LCD panel is the same for both a matte and glossy finish. I suspect that all panels are made glossy and the the anti-glare coating would be put on at the final stage of manufacture. This could cause the internal manufacturer IDs to be the same for both types.

It seems that Amazon sells a matte LTN154X3, while lcd4less sells a glossy one. Your explanation makes sense - they are probably the same panel with a different finish. I thought they were using different technologies to make them.

Thanks.
