Flexible On-Cell AMOLED tau ua qhov sib txawv ntawm qhov zoo ntawm Samsung lub flagship smartphones txij li xyoo 2017. Ntawm A3 Gen 6 cog hauv Tangjeong, Kaus Lim Qab Teb, Samsung Display pib tsim cov AMOLED hloov tau raws li cov ntim zaj duab xis nyias, siv polyimide es tsis txhob iav. substrate.
Hauv 2017, nruj (iav) thiab cov thev naus laus zis hloov pauv tau siv rau Galaxy S7 thiab S7 Ntug, feem, tab sis Galaxy S8 thiab Note 8 tsuas yog siv cov thev naus laus zis hloov pauv. Zoo ib yam li cov thev naus laus zis nruj, hloov pauv AMOLED cov lus kuj tseem siv On-Cell kov sensors, tab sis hais txog kev ua haujlwm ntawm lub cev, lub peev xwm ntsuas qhov ntsuas, cov saw hlau, cov qauv tso saib thiab kev sib koom ua ke yav tom ntej, cov qauv ntawm cov duab hloov tau yooj yim dua.
AMOLED kov sensor qauv
AMOLED yog lub teeb pom kev zoo rau nws tus kheej, yog li nws tsis tas yuav rov qab teeb thiab xim lim. Rigid AMOLED tsuas yog xav tau ib daim iav sab sauv txhawm rau txhawm rau TFT rov qab. Txij li cov iav sab sauv yog qhov yooj yim heev, qhov no yog qhov chaw zoo tshaj plaws rau cov qauv kov sensors. Samsung Display tsuas yog siv ib leeg-ib sab ITO (SITO) qauv (nrog rau cov txuas txuas txuas ntxiv thiab jumpers) ntawm lub khob ntim thiab hauv qab polarizer. Ib txheej txheej txheem ntau lub ntsiab lus kuj tseem tsim nyog rau cov qauv nkag thiab nruab nrab, tab sis nrog qhov nce ntawm cov zaub loj, Samsung Display tsis tshua tau txais nws.
Cov neeg tsim vaj huam sib luag xws li AUO thiab Hehui tau siv SITO qauv hauv ntau lub xov tooj ntse OLED panels. Samsung zaub yuav tsis tsim nruj On-Cell kov sensors ntawm nws tus kheej lithography ntau lawm kab. Txoj haujlwm no tau tawm mus rau Dongwoo, Hexin thiab Huaying, uas tau tso cai rau lawv khaws cov kab ntau lawm rau cov txheej txheem vaj huam sib luag tau txais txiaj ntsig ntau dua. On-Cell touch sensor cov chaw muag khoom yuav tsum ua cov qauv sensor hauv 5.5 lossis 6 tiam Hoobkas kom phim A2 (5.5 tiam) cov kab ntau lawm ntawm Samsung Display.
Nyob rau hauv 2015, Samsung tau tso tawm nws cov qauv flagship (Galaxy S6 Edge), uas yog raws li hloov tau AMOLED sab nraud kov tshuab. Samsung Display outsourced nws SITO zaj duab xis lag luam rau ALPS thiab Dongwoo. SITO zaj duab xis no yog laminated ntawm lub hau iav thiab AMOLED zaub polarizer (GF SITO).
Txawm li cas los xij, cov txiaj ntsig ntawm SITO zaj duab xis no yog qhov tsis zoo, vim tias lub substrate ntawm cov yeeb yaj kiab tsis nruj dua li iav, thiab nws yooj yim los ua cov khib nyiab hauv txoj kev sib tshuam. Xyoo 2016, Samsung Display tau txiav txim siab tso SITO zaj duab xis nyob rau hauv lub polarizer thiab sim siv lwm yam ntaub ntawv, xws li nyiaj nanowires.
Tso lub sensor nyob rau hauv lub polarizer pab txhim kho qhov muag pom kev ua haujlwm. Yog li ntawd, cov tuam txhab hloov pauv AMOLED zaub tau hloov los ntawm GF SITO mus rau zaj duab xis-raws li On-Cell touch sensors (lossis AP1S, Samsung Display lub sijhawm ua lag luam, tab sis nws tsis yog ib qho kev coj ua hauv kev lag luam), thaum Samsung's Galaxy S7 Edge, S8 Plus, Nco ntsoov 8 AP1S yog siv rau hauv. Zoo ib yam li cov thev naus laus zis nruj, AP1S tsis siv Samsung Display's sab hauv photolithography cov kab ntau lawm vim tias SITO zaj duab xis tuaj yeem tawm mus.
AP1S yog lub tshuab hloov pauv vim nws tsis yog qhov kev xaiv zoo tshaj plaws rau AMOLED nyias nyias. Nyob rau hauv 2016, Y-OCTA (Samsung lub lag luam lub sij hawm yog KOJ On-Cell kov AMOLED) tau thov raws li ib tug advanced saj zawg zog AMOLED zaub technology. Y-OCTA tshem tawm cov zaj duab xis substrate, tso cai rau lub kov Circuit Court ua qauv ncaj qha rau ntawm zaj duab xis encapsulation txheej. Y-OCTA ua rau AMOLED zaub nyias, tab sis nws siv lithography ntau lawm kab hauv vaj huam sib luag. Yog tias Samsung Display tso tseg nws cov tswv yim outsourcing tam sim no, nws yuav muaj qhov sib xyaw zoo thiab qhov tsis zoo.
Yog vim li cas rau saws Y-OCTA
Samsung zaub tsis tuaj yeem outsource Y-OCTA sensor duab zoo li GF SITO thiab AP1S, vim tias nws yog theem nrab hauv kev hloov pauv AMOLED ntau lawm. Outsourcing yuav coj teeb meem tsim khoom thiab lub luag haujlwm rau Samsung zaub lossis cov khoom lag luam sensor. Samsung Display tau txiav txim siab siv Y-OCAT hloov AP1S ntawm cov qauv high-end, uas txhais tau hais tias Y-OCTA yuav tsum tau coj mus rau hauv tus account hauv cov kab ntau lawm.
Cov qauv tam sim no ntawm cov ntawv xov tooj smartphone yog ib qho laj thawj rau kev hloov mus rau Y-OCAT. Qhia nrog qhov sib piv ntawm 18: 9 xav tau qhov nyias nyias thiab nqaim profile, tshwj xeeb tshaj yog rau AMOLEDs hloov tau. Y-OCTA tshem tawm ITO zaj duab xis substrate (kwv yees li 50 µm lossis ntau dua). Cov txheej txheem photolithography hauv cov kab ntau lawm tuaj yeem ua qauv ncaj qha rau qhov kov sensor (titanium / aluminium / titanium) ntawm txheej nyias zaj duab xis encapsulation (TFE), uas yog thawj coated nrog ib txheej nyias ntawm resin kom lub ntsej muag tiaj tus. Raws li rau lub kov sensor coj thiab cov zaub pixel coj mus ua ke, lawv txuas nrog lub nti los ntawm COP (chip ntawm yas substrate) txoj kev.
COP tau txo qis hauv qab ntug, tab sis yog tias TDDI tau txais yuav nyob rau yav tom ntej, kev sib dhos ntawm tag nrho cov zaub module tuaj yeem ua kom yooj yim. Kev txuag nqi suav nrog COF FPC thiab ITO nyias zaj duab xis substrates. Hlau kov sensor circuits kuj yooj yim rau khoov dua li ITO-raws li. Nws tuaj yeem siv rau yav tom ntej In-Cell qauv, qhov twg cov cathode lossis anode siv los ua tus kov sensor rau qauv. Y-OCTA siv cov kab ntau lawm photolithography rau kev ua qauv, tab sis nws kuj txo cov txiaj ntsig sib xyaw.
Yog li ntawd, kev npaj muaj peev xwm ntau dua yog xav tau, thiab nws yuav siv sij hawm qee lub sij hawm kom loj hlob. Samsung Display tab tom txiav txim siab tso cai rau L7-1 cog los nthuav nws lub peev xwm Y-OCT hauv 2018. Tam sim no, tsuas yog 5.8-inch Galaxy S8 siv Y-OCTA.
