Las Vegas – Kazuo Hirai, Sonys CEO wird die­se Prä­sen­ta­ti­on sicher­li­ch nicht so schnell ver­ges­sen. Die Gerüch­te bestä­tig­ten sich und Sony prä­sen­tier­te den welt­weit ers­ten Pro­to­ty­pen eines Ultra HD Fern­se­hers mit OLED-Tech­nik (Orga­nic Light Emit­ting Diodes). Die­ser ver­sag­te jedoch, da der ange­schlos­se­ne PC einen Feh­ler ver­ur­sach­te.

Die­ser revo­lu­tio­nä­re Fern­se­her kom­bi­niert das welt­größ­te OLED Dis­play mit leuch­ten­der 4K-Auf­lö­sung und die­sen schö­nen Inter­faces“, sprach Hirai, dreh­te sich zum Fern­se­her und sah… NICHTS – einen schwar­zen Bild­schirm. Das Publi­kum lacht, doch Hirai setz­te die Prä­sen­ta­ti­on fort…

Als er dann noch­mals auf den 56 Zoll OLED-Ultra-HD-Fern­se­her ein­ge­hen möch­te, gibt es immer noch kein Bild. Das fällt dem CEO nur noch „Excel­lent“ ein.

Wie dem auch sei, Sony darf sich rüh­men, den ers­ten Pro­to­ty­pen vor­ge­stellt zu haben, der die bei­den Fern­seh-Tech­no­lo­gi­en der Zukunft ver­bin­det.

Sony develops the World’s First and Largest “56-inch 4K OLED TV” Prototype to be exhibited at 2013 International CES

by Com­mu­ni­ca­ti­ons 01/07/2013

Tokyo, Japan – Janu­a­ry 7, 2013 – Sony Cor­po­ra­ti­on (“Sony”) announ­ced today that it has deve­lo­ped the first 4K (3840 x 2160) OLED (orga­nic light-emit­ting diode) tele­vi­si­on. To demons­tra­te its latest achie­ve­ment, Sony will dis­play a 56-inch pro­to­ty­pe at The Inter­na­tio­nal Con­su­mer Elec­tro­nics Show in Las Vegas, Neva­da.

The world’s first and lar­ge­st* 56-inch OLED TV achie­ves 4K reso­lu­ti­on by using the latest oxi­de semi­con­duc­tor TFTs and Sony’s own ‘Super Top Emis­si­on’ tech­no­lo­gies.

Up until now, in order to force light through the OLED lay­er, OLED TVs used low-tem­pe­ra­tu­re poly­si­li­con (LTPS) thin-film tran­sis­tors (TFTs). Howe­ver, the­re were some chal­len­ges inherent in the manu­fac­tu­re of lar­ge OLED dis­plays.

Using oxi­de semi­con­duc­tor TFTs Sony has been able to pro­du­ce this new lar­ger dis­play. The new OLED component’s struc­tu­re also incor­po­ra­tes Sony’s own ‘Super Top Emis­si­on’ tech­no­lo­gy, which has been suc­cess­ful­ly incor­po­ra­ted in other pro­ducts alre­a­dy intro­du­ced into the mar­ket. This ‘Super Top Emis­si­on’ tech­no­lo­gy has a high aper­tu­re ratio and enables light to be extrac­ted effi­ci­ent­ly from the structure’s OLED lay­er. By com­bi­ning two Sony deve­lo­ped tech­no­lo­gies, Sony has been able to over­co­me some of the­se chal­len­ges. This pro­to­ty­pe deli­vers all of the fea­tures expec­ted from OLED TVs, such as high con­trast, bright­ness, rapid video image res­pon­se time and rich images pro­du­ced even at wide view­ing angles, all packa­ged in a lar­ge 4K reso­lu­ti­on panel.

The OLED panel used in this pro­to­ty­pe 4K OLED TV on dis­play at the exhi­bi­ti­on was joint­ly deve­lo­ped with Tai­wa­ne­se com­pany AU Optro­nics Corp. (AUO)

Sony has long been active­ly invol­ved in the pro­duct deve­lop­ment and mass pro­duc­tion of OLED dis­plays. Begin­ning with the release of the world’s first 11-inch OLED tele­vi­si­on in 2007, Sony went on to release 17” and 25” moni­tors for pro­fes­sio­nal app­li­ca­ti­ons in 2011. On the rese­ar­ch and deve­lop­ment front, Sony has given pre­sen­ta­ti­ons on the results of its rese­ar­ch in pro­cess (manu­fac­tu­ring) tech­no­lo­gies for mid and lar­ge-sized panels as well as pre­sen­ting rese­ar­ch fin­dings on oxi­de semi­con­duc­tor TFTs and fle­xi­ble orga­nic TFTs. Sony is also active­ly working on next-gene­ra­ti­on OLED tech­no­lo­gies.

Sony will con­ti­nue to rese­ar­ch OLED tech­no­lo­gy with the goal of com­mer­cia­li­zing its new 4K OLED tele­vi­si­ons, as well as laun­ch 4K LCD TVs like the BRA­VI­As exhi­bi­ted at CES2013. From filming to edit­ing, con­tent crea­ti­on, deli­very, dis­tri­bu­ti­on and dis­play devices, Sony is making its uni­que new 4K ima­ging expe­ri­en­ce avail­able to users in a wide varie­ty of ways.
