Hauv kev sib tw ntawm OLED cov thev naus laus zis sib tw rau qhov tseeb ntawm micron, qhov ruaj khov ntawm cov khoom siv kuaj pom ncaj qha txiav txim siab qhov txiaj ntsig ntawm cov vaj huam sib luag. Cov platforms ua si granite, nrog lawv cov khoom siv ntuj thiab cov txheej txheem ua tiav, muab qhov tseeb ntawm qhov chaw ntawm ± 3um rau cov khoom siv, ua qhov tseem ceeb rau kev txo nqi thiab kev txhim kho kev ua haujlwm hauv kev lag luam.
Kev nthuav dav thermal tsawg heev, qhov yuam kev kub cais tawm: Qhov coefficient thermal nthuav dav ntawm granite tsuas yog 5-7 × 10⁻⁶ / ℃, tsawg dua ib feem peb ntawm cov khoom siv hlau. Thaum muaj cua sov tsim thaum lub sijhawm ua haujlwm ntawm cov khoom siv lossis kev hloov pauv kub ib puag ncig, nws qhov kev hloov pauv ntawm qhov ntev yuav luag xoom. Thaum qhov kub ib puag ncig hloov pauv los ntawm 10 ℃, qhov nthuav dav thiab kev cog lus ntawm lub platform 1-meter ntev tsuas yog 50-70nm, tshem tawm qhov kev sib txawv ntawm kev kuaj pom los ntawm kev hloov pauv thermal los ntawm cov hauv paus hniav.
6 zaug kev ua haujlwm damping, qhov chaw xauv qhov tseeb: Cov qauv siv lead ua los ntawm cov pob zeb tshwj xeeb ua rau granite muaj peev xwm nqus tau kev co zoo heev, thiab nws qhov kev ua haujlwm damping yog 6 zaug ntawm cov hlau cam khwb cia. Nyob rau hauv kev txav mus los ntawm cov khoom siv lossis kev cuam tshuam sab nraud, lub zog vibration tuaj yeem hloov pauv mus rau hauv lub zog thermal tam sim ntawd, xyuas kom meej tias qhov kev soj ntsuam ntes tau tswj hwm qhov chaw ruaj khov rau lub vaj huam sib luag thiab zam kev hloov pauv ntawm pixel.
Kev ruaj khov tshuaj lom neeg thiab kev ua haujlwm ntev ntev: Hauv OLED lub rooj cob qhia uas muaj cov tshuaj etching thiab cov organic solvents, granite, vim nws cov tshuaj lom neeg tsis muaj zog, tsis xeb lossis xeb, tswj tau qhov tseeb ntawm cov qauv rau kaum xyoo yam tsis muaj kev cuam tshuam. Piv nrog cov khoom siv hlau uas yooj yim laus, nws cov yam ntxwv tsis tas yuav saib xyuas tuaj yeem txuag cov tuam txhab ntau dua ib lab yuan hauv cov nqi kho khoom siv txhua xyoo.
Tom qab tsib-axis txuas CNC sib tsoo thiab nano-level polishing, qhov roughness ntawm lub granite platform yog Ra <0.05um, thiab qhov yuam kev flatness yog ± 1um / m, tso lub hauv paus ruaj khov rau qhov tseeb ntawm ± 3um. Cov ntaub ntawv ntsuas qhov tseeb ntawm lub tuam txhab OLED ua lag luam qhia tau hais tias qhov tsis zoo ntawm kev kuaj pom ntawm cov khoom siv kuaj pom uas muaj granite platforms tau txo qis los ntawm 80%, thiab qhov ua tau zoo ntawm kev kuaj pom tau nce 40%. Los ntawm Micro-OLED nanoscale kev kuaj pom mus rau qhov kev kuaj pom yooj ywm ntawm lub vijtsam foldable, granite tab tom tsav tsheb qhov kev hloov pauv meej hauv kev lag luam nrog nws cov txiaj ntsig kev ua tau zoo tsis tuaj yeem hloov pauv.
