Tshooj Ob: LED Tsav Tsheb, qhov thib ob tseem ceeb tshaj plaws rau kev coj ua.

Yog tias cov teeb ci LED suav tias yog tib neeg lub cev, ces LED zaub tsav tsheb IC yog ib qho tseem ceeb xws li lub hauv paus paj hlwb ntawm tib neeg lub hlwb, thiab nws yog tus saib xyuas lub cev lub cev ua haujlwm thiab kev xav ntawm lub hlwb.

Qhov kev ua tau zoo ntawm tus tsav tsheb IC txiav txim siab cov txiaj ntsig ntawm lub vijtsam coj zaub, tshwj xeeb tshaj yog siv cov kev ua ub no loj thiab cov chaw ua haujlwm siab, ua rau tib neeg yuav tsum nruj me ntsis rau LED zaub tsav tsheb IC.

TsavIC evolution:
Nyob rau hauv lub 90s ntawm lub xyoo pua xeem, LED zaub daim ntaub ntawv tau dominated los ntawm ib leeg thiab ob xim, siv ib tug tas li voltage tsav IC.Nyob rau hauv 1997, Tuam Tshoj tus thawj LED zaub nplooj siab tsav tswj nti 9701 tshwm sim.Nws hla 16 ntxoov grey rau 8192 ntxoov grey kom ua tiav WYSIWYG.

Tom qab ntawd, rau cov yam ntxwv ntawm LED lub teeb-emitting, tas li-tam sim no tsav los ua qhov kev xaiv zoo tshaj plaws rau cov xim puv xim LED zaub tsav tsheb, thaum lub 16-channel tsav ntau dua hloov 8-channel tsav.Thaum xyoo 1990s, Nyiv Toshiba, Allegro, thiab Ti ntawm Tebchaws Meskas tau ua tiav 16-channel cov tsav tsheb tsav tam sim no.

 Thaum pib ntawm lub xyoo pua 21st, tus tsav tsheb chips ntawm Tuam Tshoj Taiwanese tuam txhab uas muag kuj loj-tsim thiab siv.Niaj hnub no, txhawm rau daws qhov teeb meem ntawm PCB layout ntawm me me-pitch LED cov ntxaij vab tshaus, qee tus neeg tsav tsheb IC tuam ntxhab kuj tau qhia txog kev sib xyaw ua ke 48-channel LED tas li tam sim no tsav tsheb chips.

Driver IC Performance Indicators:
Ntawm cov ntsuas kev ua tau zoo ntawm LED cov ntxaij vab tshaus, qhov ntsuas tshiab thiab qib grey thiab cov duab qhia yog ib qho tseem ceeb tshaj plaws ntsuas.

Qhov no yuav tsum muaj qhov sib xws ntawm qhov tam sim no ntawm LED zaub tsav tsheb IC raws, kev sib txuas lus ceev ceev, thiab cov lus teb tsis tu ncua tam sim no.

Yav dhau los, peb yam ntawm refresh npaum li cas, greyscale, thiab kev siv tus nqi yog ib hom kev hloov kev sib raug zoo.

Txhawm rau kom ntseeg tau tias ib lossis ob qho ntawm cov ntsuas tuaj yeem ua tau zoo tshaj plaws, peb yuav tsum ua tib zoo txi ob qhov ntsuas ntxiv.

Vim li no, ntau lub LED zaub yog qhov nyuaj rau kev ua tiav qhov zoo tshaj plaws ntawm ob lub ntiaj teb hauv kev siv tswv yim, lossis lawv tsis txaus.

Cov cuab yeej siv lub koob yees duab ceev ceev yog cov kab dub thaum lawv thaij duab, lossis cov nplai grey tsis txaus, thiab cov xim ci tsis sib xws.

Nrog rau kev nce qib ntawm cov neeg tsav tsheb IC cov tuam txhab thev naus laus zis, tau muaj kev cuam tshuam hauv peb qhov teeb meem siab thiab cov teeb meem no tau daws.
Nyob rau hauv daim ntawv thov ntawm me me-pitch LED zaub, thiaj li yuav ua kom cov neeg siv lub qhov muag xis nyob rau lub sij hawm ntev, low-light thiab high-grey ua ib qho tseem ceeb tshwj xeeb rau kev ntsuam xyuas kev ua tau zoo ntawm tus tsav tsheb IC.

Tsav IC yog los ua ke lub voj voog loj loj rau hauv cov nti me me ua haujlwm, kom lub zog hluav taws xob ntawm LED video zaub tau zoo dua qub, IC zoo rau HD LED zaub video zoo, Xim muaj qhov pom kev zoo.Txhawm rau kom paub qhov siab ua kom rov zoo, tam sim no nrov IC series siv yog: MBI5153, ICN2163, SUM6086, thiab lwm yam.

 Txog tam sim no ICN2153 loj hlob sai hauv kev ua lag luam, nws kuj tseem ruaj khov tab sis tus nqi qis dua piv rau MBI5153.

MBI5153 yog los ntawm Macroblock, nws yog tus tsav nti rau LED puv xim zaub.S-PWM yog siv los txo qhov flicker ntawm daim duab.

Cov ntaub ntawv tawm tswv yim yog siv los kho qhov ci ntawm LED video screen.Ua haujlwm kub yog -40 txog +85 degrees Celsius.

ICN2153 yog los ntawm Chip Ib.Nws siv rau me me-pitch LED video zaub nrog kev cuam tshuam zoo heev.

Cov nyhuv qis-grey tsis cuam tshuam los ntawm PCB.

Nws tuaj yeem kho cov zis tam sim no thiab tswj qhov ci ntawm HD LED zaub.

Cov zaub yog daws tau zoo.Tsawg-grey blocks, nrog rau cov xim cam, pitting, thiab lwm yam tuaj yeem siv nrog txhua kab los tshem tawm cov ntawv dab.

 YONWAYTECHcoj zaub raws li cov chaw tsim khoom lag luam, peb ib txwm saib xyuas txhua qhov kev txiav txim siab los ntawm peb cov neeg siv khoom, 1920hz-3840hz refresh npaum li cas thiab 14bit-16bit coj screen rau sab hauv tsev lossis sab nraum zoov siv tuaj yeem xaiv tau.
