LCD is replacing CRT. This happens in my company also.
My company has been buying LCD monitors to replace the CRT monitors, in stages. When old CRT dies, we replace it with an LCD. No problem there.
Problem arises one or two years afterwards. The LCD monitors started to die off. Actually, it's not the LCD that conked. It's the fluorescence tube behind the LCD that quit working.
When we were using CRTs, it normally lasted 5 to 7 years before it gives us problem. Now with LCD monitors, the attrition rate is just too high ! I mean, after a year or two and many started to drop like flies. It's getting to the point that it ain't funny anymore.
With CRT monitor, if there is any problem, most of the time we can get someone to repair it. With LCD monitor, once the fluorescence tube refuses to shine anymore, there is no way to replace it. The damn thing is fused/glued together at the back of the LCD panel in such a way that it is next to impossible to remove/replace the tube. Even if we can remove the fluorescence tube, we can't find anyone who sells a new tube !
So it's a total write-off. No remedy. No nothing. Nada.
Of course we are replacing the dead LCD monitors with new LCD monitors, but I need help.
I've read somewhere that some new LCD monitors got their back-lighting from LED arrays, rather than the useless fluorescence tube, and the one uses LED arrays can last longer.
The thing is, when we go to buy LCD monitors, often there is no indication which brand / model uses the fluorescence tube, and which brand / model uses LED arrays.
I've also heard that many manufacturers outsource their LCD monitor production to companies in China or India, and there are LCD monitors with the exact brand and model, a batch may comes with LED array backlighting, but another batch, perhaps from another plant, comes with fluorescence tube.
Therefore, my question to all of you is this:
How do I know **FOR SURE** which brand and/or which model of LCD monitors are equipped with LED array backlighting ?
Thank you !
