Thaum ntsuam xyuas cov duab LED, cov neeg yuav khoom feem ntau tsom rau qhov ci ntsa iab, pixel pitch thiab refresh npaum li cas. Ib qho tseem ceeb tab sis feem ntau tsis saib xyuas yogLED binning. Binning ncaj qha cuam tshuam xim sib xws thoob plaws qhov screen thiab dhau sijhawm. Cov binning tsis zoo tuaj yeem ua rau pom cov xim sib txawv ntawm cov qauv, qhov tsis sib xws ntawm cov xim dawb, thiab maj mam hloov xim raws li cov hnub nyoog.
Kab lus no piav qhia tias LED binning txhais li cas, vim li cas nws tseem ceeb, thiab yuav ntsuas nws li cas thaum xaiv cov zaub.
LED Binning yog dab tsi?
LED binning yog txheej txheem ntawm sorting LED chips raws li lawv cov yam ntxwv kho qhov muag thiab hluav taws xob tom qab kev tsim khoom. Manufacturers kuaj txhua LED rau:
Wavelength (xim)
Brightness (kev siv zog luminous)
Forward voltage
Chips nrog cov yam ntxwv zoo sib xws tau muab faib ua "bin." High- cov lus pom zoo siv cov khoom siv nruj nruj kom cov LEDs liab, ntsuab thiab xiav hla tag nrho lub vijtsam ua haujlwm tau zoo li qub.
Vim li cas Binning Matters hauv Cov Haujlwm tiag
Inconsistent binning tuaj yeem ua rau muaj ntau yam teeb meem pom:
Xim thaj ua rau thaj- Cov qauv sib txawv qhia me ntsis txawv xim nyob rau hauv tib cov ntsiab lus
Dawb balance drift- Dawb zoo li sov dua lossis txias dua hauv qee qhov chaw
Cov xim aging sib txawv sai dua- LEDs los ntawm cov thawv dav dav tuaj yeem muaj hnub nyoog ntawm tus nqi sib txawv, ua rau lub vijtsam tsis sib xws thaum lub sijhawm
Nyuaj hauv calibration- Kev sib tw dav dav ua rau cov xim calibration nyuaj thiab tsis ruaj khov
Cov teeb meem no tshwm sim tshwj xeeb tshaj yog nyob rau hauv cov ntxaij vab tshaus loj, zoo -pitch sab hauv tsev, thiab cov ntawv thov saib nyob ze lossis ntes los ntawm lub koob yees duab.
Yuav ua li cas Binning cuam tshuam rau ntau daim ntawv thov
| Daim ntawv thov | Binning tseem ceeb | Yog vim li cas |
|---|---|---|
| Sab hauv tsev zoo -pitch video phab ntsa | Siab heev | Kev saib ze ze qhia qhov txawv xim me me |
| Theem thiab kev xauj tsev | Siab | Cov koob yees duab nthuav cov xim tsis sib xws |
| Sab nraum zoov tsau advertising | Nruab nrab mus rau siab | Loj loj ua rau module-rau-module txawv pom dua |
| Tswj chav thiab cov chaw hais kom ua | Siab | Lub sijhawm saib ntev thiab qhov tseeb xim tseem ceeb |
| Basic sab nraum zoov billboards | Nruab nrab | Kev pom ntev dua yuav txo qhov pom ntawm qhov txawv me me |
Dab tsi cov neeg yuav khoom yuav tsum kuaj xyuas
Nug txog binning qauv- Reputable manufacturers tswj wavelength thiab brightness nyob rau hauv nqaim tolerances.
Thov cov ntaub ntawv ntawm LED cov neeg muag khoom- Siab- cov hom LED zoo feem ntau muab cov khoom zoo dua thiab zoo sib xws.
Tshawb xyuas cov kev ua haujlwm calibration ntawm lub Hoobkas- Zoo binning ua ke nrog kev calibration kom tsim tau qhov zoo tshaj plaws.
Saib xyuas cov duab tiag tiag- Saib rau cov ntxaij vab tshaus loj hauv qab dawb lossis lub teeb - cov ntsiab lus xim los ntsuas qhov sib xws.
Xav txog kev ua haujlwm ntev -- Tighter binning feem ntau txhawb cov xim zoo dua nyob rau ntau xyoo ntawm kev ua haujlwm.
Tight binning tsis tshem tawm qhov xav tau ntawm calibration, tab sis nws muab lub hauv paus zoo dua. Cov khoom tsim nrog ua tib zoo xaiv LED cov khoom khaws cov xim zoo ib yam ob qho tib si ntawm kev xa khoom thiab tom qab siv txuas ntxiv.
Xaus
LED binning yog lub hauv paus tsim cov kauj ruam uas cuam tshuam cov xim sib xws thiab ntev - lub sij hawm pom kev zoo. Txawm hais tias nws tsis tshua muaj tshwm sim raws li cov ncauj lus tshwj xeeb, qhov zoo ntawm binning feem ntau cais cov ntxaij vab tshaus nruab nrab ntawm cov kws tshaj lij- qib qhia. Cov neeg yuav khoom uas nkag siab thiab ntsuas cov kev coj ua binning yog qhov zoo dua los xaiv cov khoom uas xa cov duab zoo ib yam, ruaj khov thiab txhim khu kev qha.
