i see on the gp2x wiz web site that you can play outdoor ?
do you think , you can play in direct sun with it ?
Can you play outdoor and have a bright screen like seeing on the picture on the web site ?


(i love the gp32 nlu because its so bright in sunlight )

lol, it's another one of your sunlight threads


OLED screens are known for their great viewing angles and clarity outside.

LOL LOL I LOVE SUNLIGHT TREADS oh yeah LONG LIVE TO SUNLIGHT TREADS

i always dream to play outside with a handheld that have some power. i love my gp32 nlu in outdoor, but i cant play snes emulation, and the nes emulation is not so great, and the genesis emu has frameskip.
i play gamegear ans sms games 80% of time... and little wizard

( its from you i bought my gp32 ? isnt ?

Viewing angle, yes they emit light like an LED so that makes sense.

Their viewability in sunlight though should be no better than a bright LCD, and much worse than a transreflective LCD though.

Well no, doesn't the OLED display itself emit light without the need for a backlight? This makes it more like a transflective LCD

The Wiz screen looks much better outdoors than the GP32 Blu's and the GP2X's. When under direct sunlight keeping it under your own body's shadow suffices to make it usable, but it obviously performs best under plentiful shade. But I can't imagine myself doing anything that requires attentive watching while directly under the sun's light, be it playing games or reading paper books.

And the viewing angle is simply amazing

Hopefully only Boktai series on original GBA requires playing it outdoor.

not much use for me playing games on it outside. It always rains where I live.

thats what cases are for haha.

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.

im playing a lot in direct sun.. so for me its important. if the gp2x wiz is playable in direct sunlight maybe i will consider to buy one someday. For now i will continue to use my gp32 nlu for direct sulight or my gba.

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.

If the sunlight is brighter than the OLED brightness it will not be viewable. The same is not true with a Transreflective LCD.

The GP2X is not transreflective though. In this case OLED may be a bit more viewable as it has more contrast, but don't expect it to be as good as a GBA, PDA etc with a reflective screen in direct sunlight.

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.


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.

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).

"no matter how bright the ambient light."

sound like the end of the things thsoe philisophers say... or maybe they just rhyme lol.

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?

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.



Correct.

does the pandora have that too?

I tried it myself... PLAYABLE, yes, but only if you use your head as a shadow. Direct sunlight is a bit too much.

ENJOYABLE... that's the other question

These questions are for EvilDragon:

i want your advice, i know you tried the gp2x wiz in sunlight.

i play a lot of time with my handheld in direct sunlight. more precisely with my gba and gp32 nlu (no light edition) and they are wonderful in direct sunlight. VERY ENJOYABLE!

So is it a mistake if i buy the gp2x wiz to play in sunlight ? i just want to be sure... what do you think about that honestly ?? did you ever try a gba or a gp32 nlu in direct sunlight? how they compare to the gp2x wiz ?

THANKS A LOT FOR ANSWER I REALLY APPRECIATE IT.

The OLED screen will not be as good as the GBA or NLU in direct sunlight.

The screen of a reflective LCD such as a GBA or GP32 NLU gets BETTER the brighter the sunlight is, and OLED gets worse the brighter the sunlight.

Transparent OLED

Transparent organic light-emitting device (TOLED) uses a proprietary transparent contact to create displays that can be made to be top-only emitting, bottom-only emitting, or both top and bottom emitting (transparent). TOLEDs can greatly improve contrast, making it much easier to view displays in bright sunlight. This technology is used in Head-up displays.

But the Wiz doesn't use a TOLED screen

* - AM OLED = Active Matrix OLED device
* - FOLED = Flexible Organic Light Emitting Diode (UDC)
* - OLED = Organic Light Emitting Diode/Device/Display
* - PhOLED = Phosphorescent Organic Light Emitting Diode (UDC)
* - PLED = Polymer Light Emitting Diode (CDT)
* - PM OLED = Passive Matrix OLED device
* - POLED = Polymer Organic Light Emitting Diode (CDT)
* - RCOLED = Resonant Color Organic Light Emitting Diode
* - SmOLED = Small Molecule Organic Light Emitting Diode (Kodak)
* - SOLED = Stacked Organic Light Emitting Diode (UDC)
* - TOLED = Transparent Organic Light Emitting Diode (UDC)

Which one does it use?

The Wiz uses an AMOLED display.

thanks WarmFluffyUK.

/runs off to research AMOLED for something to occupy self while waiting... (I hate waiting!) for Wiz preorder to ship.
