Schermi OLED o LCD e plasma?


OLED è l'acronimo di Organic Light Emitting Diode ovvero diodo organico ad emissione di luce.La nuova frontiera della tecnologia degli schermi è arrivata. In soldoni l'OLED permette di realizzare display a colori con la capacità di emettere luce propria: a differenza dei display normali a cristalli liquidi.
Credete sia una cosa da poco? Faccio notare che con OLED non sono necessari componenti aggiuntivi per illuminare uno schermo. Ad esempio il monitor del portatile da cui scrivo ora è composto da 2 parti fondamentali: I cristalli liquidi e da una lampada restrostante che accendendosi li illumina e ci permette di vedere (la lampada dei monitor dei portatili è una delle componenti più fragili e sottoposte a rischio di rottura). Lo schermo OLED invece non necessita di questa luce ma permette di far vedere lo schermo indipendentemente.
La prima conseguenza immediata è che i display saranno più sottili e consumeranno molto meno. Il vantaggio è duplice. Sia in termini di spazio sia per l'ambiente.

Altra cosa fondamentale:
A causa della natura monopolare degli strati di materiale organico, i display OLED conducono corrente solo in una direzione, comportandosi quindi in modo analogo a un diodo; di qui il nome di O-LED, per similitudine coi LED.(wikipedia).

Come ogni tecnologia di avanguardia l'OLED sembra soffrire di alcuni difetti. Primo fra tutti il prezzo ancora molto alto (ma daltronde lo era anche delle tv plasma fino a poco tempo fa). In secondo luogo gli OLED sembrano avere una longevità inferiore a quella degli schermi LCD o PLASMA poichè il materiale organico di cui sono composti sembra perdere le sue proprietà di emissione di luce dopo poche migliaia di ore di utilizzo. A causa sopratutto di questo problema il commercio di questi schermi è molto limitato ancora. Non è escluso che in futuro però possano diventare molto diffusi facendoci risparmiare un bel po di soldi di consumo di energia.

Tra l'altro la Sony ha presentato gia all'ultimo Consumer Electronics Show di Las Vegas una gamma di televisori OLED. I monitor più piccoli hanno una risoluzione di 1024x600 punti mentre quello da 27" ha una risoluzione di 1920x1080 pixel. Tutti sono provvisti di ingressi HDMI. Sono sottilissimi davvero e con una resa davvero impressionante. Quindi vi sconsiglio di acquistare televisori al plasma o olc al momento. Se volete proprio farlo prendeteli LCD che costano meno e rendono uguale e vi garantiscono un notevole risparmio energetico.

Sicuramente troveranno il modo di migliorare gli O-Led.

Sarei curioso di sapere, a parte il minor consumo di energia, se l'impatto ambientale è simile, migliore o peggiore delle metodologie di costruzione finora utilizzate.

Comunque è un post utile, come sempre.

gli oled verranno usati non solo come monitor ma anke come lampade!! già se ne parla, ad esempio per l'interno delle automobili (dato ke sono sottili come 1 foglio di carta e flessibili seguono la sagoma della carrozzeria)...
consumi ridottissimi...qlc problema ancora x la durata e x il colore blu (non so xkè ma è così, almeno qlc anno fa)..
cmq già li usano su certi lettori mp3 e cellulari! quindi sono già sul mercato!

Ciao,
mi sembra che gli OLED saranno piuttosto ecologici, http://schermioled.it e dovrebbero essere non solo le TV e le lampade del futuro prossimo, ma anche gl ischermi flessbili, cioè pienamente indossabili!!!
