Which Display (AMOLED, LCD) for my aspie eyes?

Post Reply New Topic

Hi folks,

I have bought already some laptops, but all of them give me a headache, though some more than others. I think its due to the artificial lighting in the LCD display. Now I wonder, if a smartphone or tablet would be better for my eyes due to their displays, and I should buy some and use them as often as possible, and the laptops only when necessary.

Recently I have seen some smartphones in the local retail store, e.g. Samsung Galaxy S5, and their displays seemed to be "different", but I don't know if they give me less headache. However I don't want to spend $500 dollars and then find out that those displays also give me also as much headaches as my laptops do.

What are your experiences? Do you tablet displays also give you a headache as the usual LCD displays of your laptops?

thanks for your comments,

John

LCD in and of itself doesn't hurt me.
the problem with LCD is when i reduce its brightness, LCD does that by slowing down its flicker, which gets it into the visible and headache range, but i got a 3rd party program (F.lux) that also effectively lowers brightness, by saturating the palette with yellow.

AMOLED doesn't have these problems (i got an galaxy S2, which also uses AMOLED), those screens are, apperantly, ably by actually reducing the brightness of their pixels in absolute terms, rather then reducing the amount of flashes they make.

now, the lowest setting is still on the strong end, but that's with all screens.

I prefer AMOLED over LCDs but it really varies person to person I think.

*shrug* I just have my computer hooked into a 39" led hd tv. It's beautiful and gives you a comfortable distance from the screen that hand held a won't provide.

If you have a LED-TV(That is actually a marketing name, It's really a LCD with a LED instead of a CCFL for a back light.). One of the tricks that they use to dim the back light is to pulse the light on and off really fast. This pulsing technique is called Pulse Width Modulation(PWM). PWM works by controlling the amount of time the light is on and the amount of time its off. for example. If you want your display to be 25% bright. during a pulse cycle. the light is turn on at 100% power for 25% of the pulse time and is turned completely off for 75% of the pulse time. because this pulsing happen so fast, your eyes only see the light glowing at 25% brightness.

I properly make PWM driver should run at about 500Hz speed, but some older and cheaper ones may be operating as low as 30Hz. theses are the ones that can give an autistic person a headache and even cause a meltdown. They are also not good for anyone that is prone to seizures as well. Plus, they can be an eyestrain for just about anybody.
