Iftiinkooda iyo kala duwanaanshahooda waxay la mid yihiin talefishinnada OLED, laakiin kharashkoodu aad ayuu uga hooseeyaa mana jirto khatar shaashadda gubanaysa.

Haddaba waa maxay sax ahaan Mini LED?

Waqtigan xaadirka ah, Mini LED-ka aan ka hadlayno maahan tignoolajiyada soo bandhigida gabi ahaanba cusub, laakiin waa xal la wanaajiyey oo ah isha dambe ee muraayadaha dareeraha ah, taas oo loo fahmi karo kor u qaadista tignoolajiyada iftiinka dambe.

Inta badan TV-yada LCD waxay u adeegsadaan LED (Light Emitting Diode) sidii nalka dambe, halka Mini LED-yada ay isticmaalaan Mini LED, oo ah il iftiin yar oo ka yar LED-yada caadiga ah.Baaxadda LED-ka-yar waa ku dhawaad ​​200 microns (0.008 inji), taas oo shan-meelood meel ka ah cabbirka LED-ga caadiga ah ee loo isticmaalo muraayadaha LCD.

Xajmigooda yar awgeed, si badan ayaa loogu qaybin karaa shaashadda oo dhan.Marka ay jirto iftiinka dambe ee LED ku filan ee shaashadda, xakamaynta dhalaalka, gradient midabka, iyo dhinacyada kale ee shaashadda si fiican ayaa loo xakameyn karaa si ku filan, sidaas darteed bixinta tayada muuqaal wanaagsan.

TV-ga saxda ah ee Mini LED wuxuu si toos ah u adeegsadaa Mini LED sida pixels halkii uu ka isticmaali lahaa iftiinka dambe.Samsung ayaa sii daysay TV-ga Mini LED ee 110 inch ah CES 2021, kaas oo la bilaabi doono Maarso, laakiin way adagtahay in la arko badeecooyinka heerka sare ah oo ka soo muuqda qoysaska badankood.

Summooyinkee ayaa qorsheynaya inay bilaabaan alaabooyinka LED-ka-yar?

Waxaan mar hore ku aragnay CES-ga sanadkan in TCL ay sii daysay "ODZero" Mini LED TV.Xaqiiqdii, TCL waxay sidoo kale ahayd soo-saarehii ugu horreeyay ee bilaabay Mini LED TV-yada.LG QNED TV-yada laga bilaabay CES iyo Samsung's Neo QLED TV-yada sidoo kale waxay isticmaalaan tignoolajiyada iftiinka dambe ee LED-ka.

Maxaa ka qaldan iftiinka dambe ee Mini LED?

1. Background ee horumarinta iftiinka dambe ee Mini LED

Sida Shiinuhu u galo heerka caadiga ah ee ka-hortagga iyo xakamaynta cudurrada faafa, isbeddelka soo kabashada ee isticmaalka ayaa si tartiib tartiib ah u xoojinaya.Dib u milicsiga sanadka 2020, "dhaqaalaha guriga" shaki la'aan waa mawduuca ugu kulul ee macaamiisha, iyo "dhaqaalaha guriga" waa uu kobcay, iyadoo sidoo kale taageeraysa kobaca guud ee tignoolajiyada cusub ee soo bandhigida sida 8K, dhibcaha quantum, iyo Mini LED. .Sidaa darteed, iyada oo kor u qaadista xooggan ee shirkadaha hormuudka ah sida Samsung, LG, Apple, TCL, iyo BOE, TV-yada yaryar ee qeexitaankoodu sarreeyo oo si toos ah hoos ugu dhigaya iftiinka dambe ee Mini LED waxay noqdeen goob warshadeed.Sannadka 2023, waxaa la filayaa in qiimaha suuqa ee sabuuradaha TV-ga ee isticmaalaya laydhka dambe ee Mini LED uu gaadhi doono 8.2 bilyan oo doolarka Maraykanka ah, iyadoo 20% kharashka ku baxaya uu ku jiro Chips Mini LED.

Iftiinka dambe ee tooska ah ee Mini LED wuxuu leeyahay faa'iidooyinka xallinta sare, cimriga dheer, hufnaanta iftiinka sare, iyo kalsoonida sare.Isla mar ahaantaana, Mini LED, oo ay weheliso kontoroolka aagagga dimming maxalliga ah, waxay gaari kartaa isbarbardhigga sare ee HDR;Marka lagu daro dhibcaha gamut quantum midabka sare, gamut midab ballaaran>110% NTSC waa la gaari karaa.Sidaa darteed, tikniyoolajiyadda Mini LED waxay soo jiidatay dareen badan waxayna noqotay isbeddel lama huraan u ah tignoolajiyada iyo horumarka suuqa.

2. Mini LED cabbiraha chip backlight

Semiconductor Guoxing, oo ah shirkad si buuxda loo leeyahay ee Guoxing Optoelectronics, ayaa si firfircoon u horumarisay Mini LED epitaxy iyo tignoolajiyada chip-ka ee goobta codsiyada iftiinka dambe ee Mini LED.Horumaro farsamo oo muhiim ah ayaa lagu sameeyay isku halaynta badeecada, awoodda lidka-static, xasiloonida alxanka, iyo joogteynta midabka iftiinka, iyo laba taxane ah oo ah alaabada chip-light backlight mini, oo ay ku jiraan 1021 iyo 0620, ayaa la sameeyay.Isla mar ahaantaana, si loo waafajiyo shuruudaha xirmooyinka Mini COG, Guoxing Semiconductor waxay soo saartay wax soo saar cusub oo koronto ah oo 0620 ah, siinaya macaamiisha fursado badan.

3. Astaamaha yar yar ee nalka dambe ee LED

1. Naqshadeynta qaab-dhismeedka epitaxial-ka sarreeya ee joogtada ah, oo leh awood xooggan oo ka-hortagga-static ee chip

Si kor loogu qaado xoogga mawjadda dhererka ee chips-ka-yar ee LED-ka, Guoxing Semiconductor wuxuu qaataa tignoolajiyada xakamaynta cadaadiska lakabka epitaxial gaar ah si loo yareeyo walbahaarka gudaha oo loo hubiyo joogtaynta habka kobaca wanaagsan ee quantumMarka la eego chips-ka, xal loo habeeyey oo aadka la isku halleyn karo oo DBR ah ayaa loo isticmaalaa si loo gaaro awoodaha lidka ku ah aadka u sarreeya.Marka loo eego natiijooyinka baaritaanka shaybaarka qolo saddexaad, awoodda anti-static ee Guoxing Semiconductor Mini LED chip backlight waxay dhaafi kartaa 8000V, waxqabadka anti-static ee alaabadu waxay gaartaa safka hore ee warshadaha.
