OLED screens are known for their great viewing angles and clarity outside.pandora said:lol, it's another one of your sunlight threads![]()

WarmFluffyUK said:I have from a reliable source that the Wiz is playable in direct sunlight and the viewing angle is about 85 degrees. The screen is an AMOLED which doesn't require any backlight, this increases battery life and makes the unit much lighter.
Yes it emits light. That means it is EMMISIVE and not reflective at all. Afterall transREFLECTIVE means that is will REFLECT bright light such as sunlight.Peter R said:Well no, doesn't the OLED display itself emit light without the need for a backlight? This makes it more like a transflective LCD![]()
An OLED display is entirely different. Each subpixel is emitting its own light, hence the term emissive. There is nothing to reflect ambient light. The reason that OLED displays often work better than transmissive LCD panels in daylight conditions is because they are bright enough that the ambient light is not able to wash them out. Direct sunlight is usually enough to wash out even the best of them, though. Reflective LCD panels look even better in direct sunlight, and transflective panels don't look great, but they are always readable, no matter how bright the ambient light.Peter R said:Just because the OLED is emissive it is not transmissive. It may perfectly well reflect light far better than the GP2x LCD.
I don't think you understand.
For a LCD display to be visible, light has to pass through the liquid crystal layer and hit your eye. There are three methods for doing this, and they are generally called reflective, transmissive, and transflective (or transflexive).
In a reflective display, ambient light (or light from a frontlight) passes through the liquid crystal layer from the front, bounces off a reflective layer and back through the liquid crystal layer, and travels out to your eye.
In a transmissive panel, light travels from the backlight through the LC layer, and on to you.
A transflective panel adds a semi-reflective layer between the backlight and the LC layer. Under low ambient light conditions, the display works like a normal transmissive panel. Under high ambient light conditions (daylight), the ambient light reflects off of the semi-reflective layer and bounces back through to your eye.

Try and talk down to me again and the elitist Sam Fisher shall have to return to force you to know just how much I know against your will.
However, I choose not to argue as being correct got me banned once more (Though a very noisy certain french member did help aggrivate my situation that time).

It was meant as a general tutorial on how different display technologies work, since many people don't really know. The fact that you seemed to think the OLED "may perfectly well reflect light far better than the GP2x LCD" indicated that you needed some clarification as well.
vapourstreak said:anyways, so the screen is not the actual thing that makes it sunlight readable, its the brightness of the OLED pixels? so its not a wierd layer of sunlight absorbing material or anything, right?
Correct.
I tried it myself... PLAYABLE, yes, but only if you use your head as a shadow. Direct sunlight is a bit too much.WarmFluffyUK said:I have from a reliable source that the Wiz is playable in direct sunlight and the viewing angle is about 85 degrees.
