Los ntawm kev ua lag luam tshwj xeeb ntawm cov ntawv loj dua ntawm XR thiab VP mus rau cov ntawv thov super-fine-pitch ntawm mini-/micro-LEDs tsom rau cov khoom siv sab hauv tsev, nrog rau cov tsev ua yeeb yam, chav kev ruaj ntseg, thiab lwm yam, kev siv LED zaub tseem loj tuaj. Raws li kev tshawb fawb kev lag luam xyoo 2023 los ntawm LEDinside, cov ntawv thov no tau pab txhawb rau kev lag luam LED kev nthuav dav. Kev ua lag luam tus nqi ntawm LED zaub sector yuav tsum ncav cuag $ 13 nphom hauv 2026, nrog kev kwv yees CAGR ntawm 14% los ntawm 2021 txog 2026.
Lus Cim 1: LEDinside: Qhia txog Kev Ntsuas Tus Nqi thiab Kev Pom Zoo ntawm Lub Ntiaj Teb LED Zaub Market
XR / VP daim ntawv thov thov qeeb-suab thiab ntau lub koob yees duab ua yeeb yaj kiab, thiab LED zaub tuaj yeem tswj tau 240 FPS video pub.
Kev ua yeeb yaj kiab ntau lub koob yees duab tau dhau los ua neeg nyiam ua ib txoj hauv kev los txuag cov nuj nqis tua thiab txhawb kev tua ntau yam. Tsuas yog ob lub koob yees duab tuaj yeem ntes cov duab los ntawm LED cov ntxaij vab tshaus uas ua kom 60 ntas ib ob. Txawm li cas los xij, plaub lub koob yees duab tuaj yeem sau tib lub sijhawm ntawm LED cov ntxaij vab tshaus uas tuav 240 ntas ib ob. Rau cov kev pab cuam tsom rau cov neeg tuaj saib thoob ntiaj teb, cov txheej txheem tsim khoom no yooj yim dua. Kev tshaj tawm rau lwm lub tebchaws yuav raug muab sib txawv thiab raug ntes los ntawm cov koob yees duab sib txawv. 240 cov duab raug coj mus rau ib qho thib ob thiab rov ua dua hauv 4 vib nas this rau kev yees duab qeeb. Qhov no txhim kho smoothness thiab txo cov neeg ua yeeb yam kev sib tw ua haujlwm.
High-scan LED zaub kom txo cov khoom suav; tsav tsheb ICs nrog QFN pob kom txo cov kev sib tw txij nkawm; mini-/micro-LED zaub tau hloov kho mus rau 8K daws teeb meem
Qhov kev daws teeb meem ntawm mini-/micro-LED cov ntxaij vab tshaus upscales raws li cov zaub yuav tsum tau nce. Ntawm ISE 2023, LG tau nthuav tawm lub micro-LED vaj huam sib luag nrog 8K daws teeb meem, ua kom pom qhov tsis tu ncua ntawm kev daws teeb meem nce ntxiv. Tsis tas li ntawd, LED zaub ua me me vim qhov txo qis pixel suab. Qhov no qhia tau hais tias LED cov ntxaij vab tshaus tau dhau los ua neeg nyiam hauv kev lag luam.
Piv nrog rau 32-scan design nrog tib 48 raws, LED zaub nrog 90-scan design yuav txo tus tsav IC suav los ntawm 65% nyob rau hauv teb rau teeb pom kev zoo pixels tshwm sim los ntawm kev txo pixel suab thiab kev daws teeb meem upscaling . Tsis tas li ntawd, peb yuav tsum tsom mus rau cov tsav tsheb IC pob. LED modules yog kim kho, thiab tsav tsheb sib xyaw circuits (ICs) nrog QFN pob yog yooj yim dua rau rework dua li cov uas muaj pob BGA. Tus nqi siab yuav raug txo kom zoo li no.
LED zaub tsav tsheb integrated circuit yog npaj rau gigabit zaus|Siv cov zaus tsawg dua los simulate ntau zaus
Qhov "core zaus" ntawm LED tsav tsheb sib xyaw ua ke yog qhov tseem ceeb rau kev txhawb nqa LED cov lus qhia nrog cov ncej siab lossis cov qauv scan siab thaum khaws cia 16-ntsis greyscale ntawm tus nqi tshiab ntawm 7,680. Macroblock txhim kho cov tsav tsheb sib xyaw ua ke los ntawm "algorithm optimization" thiab "txhim kho kev suav lub zog." Qhov no qhia tau hais tias tus tsav tsheb IC tuaj yeem ncav cuag 240MHz GCLK los ntawm 30MHz GCLK los ntawm simulating 8X core zaus. Txo tus tsav tsheb IC qhov chaw thau khoom ua rau txo qis kev siv hluav taws xob thiab ua kom tiav ntawm cov khoom siv high-end.

MBI5780|Mini-/micro-LED cov ntxaij vab tshaus nrog lub suab zoo heev
48 channels, scan-sharing architecture, kev sib koom ua ke zoo heev, qhov siab tshaj plaws 90-scan design, thiab siv suab pib ntawm 0.4mm yog cov yam ntxwv ntawm MBI5762 khoom. Tsis tas li ntawd, nws khaws cov khoom ua tau zoo thiab muaj 120 ntas ib ob. Qhov pom kev ua tau zoo yuav cuam tshuam los ntawm kev siv hluav taws xob vim tias qhov me me siv pixel suab. Kev siv hluav taws xob zoo heev yog pom hauv cov duab thermal hauv qab no. Qhov sib txawv ntawm cheeb tsam nrog thiab tsis muaj tsav tsheb ICs tsuas yog 4 degree. PCB muaj qhov kub thiab txias hauv qab 40 degree.
Los ntawm kev daws cov teeb meem kev siv hluav taws xob thiab hluav taws xob, Macroblock txhim kho cov kev daws teeb meem rau cov ntawv thov super-fine-pitch zaub thaum hais txog cov teeb meem loj ntawm XR thiab VP. Yog tsis muaj kev poob siab, qhov no yuav pab tau high-end LED zaub muaj lub neej yav tom ntej.
