Cov xim puv xim LED qhia tau hais tias ib feem ntawm cov duab tsis ci thaum hloov qhov chaw, lossis qhov chaw uas yuav tsum ci tsis ci, thiab qhov chaw uas yuav tsum tsis txhob ci tseem nyob. Yog lawm, yog, cov no tuaj yeem tshwm sim los ntawm pixel tawm ntawm kev tswj hwm ntawm cov xim puv xim LED. , Yog vim li cas thiab yuav daws tau li cas?
Tawm-ntawm-tswj pixels ntawm tag nrho-xim LED zaub yog ib qho teeb meem tshwm sim. Yog vim li cas rau qhov kev xav no thiab yuav daws li cas? Cov hauv qab no yog cov ntaub ntawv qhia los ntawm Winbond Technology:
Feem ntau, cov khoom siv pixel ntau yog 2R1G1B (2 lub teeb liab, 1 lub teeb ntsuab, thiab 1 lub teeb xiav, tib yam li hauv qab no) thiab 1R1G1B, thiab tawm ntawm kev tswj feem ntau tsis yog xim liab, ntsuab, thiab xiav hauv tib lub pixel. Txhua lub teeb tsis muaj kev tswj hwm tib lub sijhawm, tab sis ntev npaum li ib lub teeb tsis muaj kev tswj hwm, peb xav tias lub pixel tsis tswj tau.
Full xim coj zaub
Yog li ntawd, nws tuaj yeem txiav txim siab tias lub ntsiab yog vim li cas rau pixel tawm ntawm kev tswj hwm ntawm tag nrho cov xim LED zaub yog qhov tawm-ntawm-tswj ntawm LED teeb. Cov laj thawj tseem ceeb ntawm qhov tsis ua haujlwm ntawm LED teeb tuaj yeem muab faib ua ob yam: ib qho yog qhov tsis zoo ntawm LED nws tus kheej; lwm qhov yog kev siv tsis raug ntawm txoj kev.
LED tsis ua haujlwm tsis tuaj yeem pom nyob rau hauv niaj hnub tshuaj xyuas thiab kuaj ntawm LEDs. Nyob rau hauv cov xwm txheej hnyav xws li kub, tsis kub, thiab kub hloov ceev, nws yog tshwm sim los ntawm qhov sib txawv ntawm thermal expansion coefficients ntawm cov ntaub ntawv xws li LED chips, epoxy resin, brackets, inner leads, bonding kua nplaum, PPA khob, thiab lwm yam. uas ua rau muaj kev ntxhov siab sab hauv. Lub mechanism ntawm LED tsis ua hauj lwm los ntawm electrostatic paug yog heev nyuaj. Cov khoom siv, cov cuab yeej, cov cuab yeej siv thiab tib neeg lub cev yuav raug them nrog hluav taws xob zoo li qub thiab tawm mus rau nws. Qhov hluav taws xob zoo li qub no tuaj yeem nyob ntawm ntau pua ntawm volts mus rau kaum tawm txhiab volts, thiab lub sijhawm tso tawm yog nyob ntawm qhov kev txiav txim ntawm nanoseconds. qib.
Yog tias lub raj xiav-ntsuab tsis ua haujlwm, nws feem ntau tshwm sim los ntawm kev tawg ntawm LED-PN kev sib tshuam los ntawm electrostatic paug. Vim cov txheej txheem tsim khoom nyuaj ntawm LED cov ntxaij vab tshaus, electrostatic paug yog qhov nyuaj los tiv thaiv. Yog li ntawd, kev tiv thaiv electrostatic yuav tsum khiav los ntawm tag nrho cov txheej txheem ntau lawm.
Tsis tas li ntawd, nyob rau hauv lub sijhawm sib txawv, qhov xav tau tiag tiag rau pixel tawm ntawm-tswj tus nqi sib txawv. Cov ntsuas ntawm cov xim puv xim LED cov ntxaij vab tshaus yuav tsum tau tswj tsis pub dhau ib feem pua; cov ntsuas ntawm monochrome LED zaub cov ntxaij vab tshaus yuav tsum tau tswj tsis pub dhau ib feem kaum.
