AMOLED Displays Are Now Cheaper To Produce Than LCD (androidauthority.com)
An anonymous reader quotes an article on AndroidAuthority: Optics pundits have been crowing about AMOLED destroying LCD for a while now: they are thinner, brighter, more energy efficient and arguably offer better colors, higher contrast, and deeper saturation than LCD. The biggest barrier stopping AMOLED from taking over as the smartphone display technology of choice has been price. Until now that is. As predicted two years ago, it has only taken 24 months for AMOLED production costs to fall below that of LCD. Production costs in the first quarter for a 5-inch Full HD smartphone display are $14.30 for an AMOLED panel and $14.60 for an LCD display. In the fourth quarter of 2015, these figures were $17.10 and $15.70, respectively. [...] With AMOLED production costs dropping below LCD for the first time, AMOLED panels will soon become the default display technology choice for manufacturers on their mid-range and entry-level devices as well.
You could actually power an LCD with 120 Hz, that's not the problem. There is just no reason to do so, differently than with CRTs. CRTs have a luminescense coating on the inside of the tube. It gets hit by the electron ray (cathode ray, hence the name), and lights up. It takes some time, until it goes out again. If this time is too long, all movements on the screen are blurred. If this is too short, the screen gets too dark and flickers. If we use a stronger cathode ray, the luminescense coating wears out too quickly and burns in. So the only way we can have a bright, non-blurry CRT picture is increasing the frequency. In an ideal world, a picture frequency of around 20 would suffice. Cinemas use 24 pictures per second, and not many complain about the picture flashing too much or movements being blurry. It works, because the time between picture frames is much smaller than the time we see the single picture frame. LCDs at 60 Hz are completely ok, but a CRT at 60 Hz flickers like an old TV set.
LCD's from a decade ago. I have TONS of LCD monitors with LED back lights that still work perfectly 6-8-10- even 12 years later. Hell I have a pair of ELO touchscreen monitors that are 14 years old that still work great and they have the old CFL backlights.
anything made today? it's all shit made as cheap as possible to make sure they break.
Do not look at laser with remaining good eye.
Heat and power consumption? A customer has a plasma set near in a confined space I have to work and it's like standing by a space heater.
From what I understand, the blue OLED ages at a faster rate than the rest of the display, which means that it will appear to turn yellow over time. If you have a static image on the display, then it will age unevenly.
LCD panels don't age in a way that makes the colors change, so they don't get burn in (the closest thing they get to burn in is image persistence, which is only temporary.)
