Okay, really boring stuff about the displays: LED and OLED - those I can tell you with certainty that they "never" fail - but do decrease in output over time, fairly predictably, to a point that is considered failure. That was my field. They're unlike an incandescent lamp, that decreases in output, but fails all at once (the filament finally fails, and breaks the circuit). They give you an expected life on them base on a sample. So if you have a 10,000 hour bulb, it's the point at which 50% of the sample failed. So you can have some that fail within a few hours, and "hero bulbs" that last hundreds of thousands of hours. The one on my desk now is a 2,000 hr bulb that's been in use for probably been in use for 80,000 hours.I sure like to met these people who makes these predictions. As I too have heard these claims and yet we also know that there are no 100 year old flash memory to research. Same is true for OLEDs screens. Because I often find their predictions doesn't end up true anyway. Like I heard electrolytic capacitors are only going to last about 10 years before they dry out and that's about it. Yet I have some that are over 50 years old and are still working just fine.
In LED & OLED, since they continue to produce light (assuming the electronics that drive them last) indefinitely, their failure is something called L70 - the hours of operation at which the samples have decreased output to the point that they're only producing 70% of initial output. And the LED's are very consistent and predictable.
But----the display is only a minor part of the mod. They have so many components, that it's like a chain, and last only as long as the weakest link. Having a dna or Dicodes mod is certainly better, but there are other fail points that are impossible to predict. I'd say Dicodes might be a better choice because they don't just sell chips to any modder that wants them, and have more control over all the components. Hell, I'll bet there are Smok mods that've been in daily use for years that still function - but fewer than those mods that use better components.
Anyway, boring stuff, but I haven't had a chance to discuss lighting in a while, so thanks for indulging me!
