Dhinaca bandhigga, marka aynu xusnobandhigyada LED, Waxaan aaminsanahay in qof kastaa liis gareyn karo faa'iidooyinkooda badan, sida "weyn" iyo "iftiin", pixel sare, aan lahayn kala-bax, iyo midabka midabka ballaaran.Shaashadaha LED-yada ayaa sidoo kale si adag ula tartamay LCD, saadaalinta, iyo meelaha kale ee goobta bandhigga faa'iidooyinkan dartood.Erayada ay ka midka yihiin "shaashadda weyn" iyo "shaashadda weyn" waxay ka buuxaan qaddarin ay u hayaan shaashadaha LED-ka.Shaki la'aan, faa'iidada ugu weyn ee muraayadaha LED-yada ayaa ah inay yihiin "weyn oo aan toos ahayn".Tartanka udhaxeeya shaashadaha LCD-ga iyo muraayadaha bandhiga LED-ka ayaa wali ah mid aad u adag laakiin waa mid xasiloon, laakiin marka la eego horumarka tignoolajiyada, shaashadaha LED-yada ayaa si tartiib tartiib ah u kordhaya xaaladaha codsiga terminal yar ee garoonka waxayna qabsanayaan qaar ka mid ah suuqa shaashadda LCD.Gelitaanka goobta bandhigga ganacsiga ee suuqa codsiyada xirfadlaha ah, baaxadda codsiga ee bandhigyada LED ayaa si joogto ah u ballaarinaya, jidkeeda horumarinta waxaa la dhihi karaa "weyn" ilaa "yar".
Kahor horumarka iyo qaan-gaadhka tignoolajiyada bandhiga LED, tignoolajiyada bandhiga shaashadda guud ee suuqa waxay ahayd DLP iyo LCD oo kala qaybiyay shaashado waaweyn.Shaashado hore oo aad u waaweyn ayaa inta badan ka koobnaa bandhigyo badan oo DLP ah oo leh tolmo cidhiidhi ah.Iyadoo ay soo ifbaxday bandhigyo LCD ah oo leh faa'iidooyin qiimihiisu yahay, saamiga suuqa ee LCD kala qaybinta shaashadaha waaweyn ayaa si tartiib tartiib ah u kordhay.Soo-celinta alaabooyinka soo-bandhigidda LCD waxay inta badan ka muuqdaan laba tilmaame oo farsamo, mid waa tolid, kan kalena waa dhalaal.Iyada oo ay ugu wacan tahay astaamaha soo-bandhigidda ee bandhigyada LCD, suurtagal maaha in la gaaro heer sare oo dhalaal ah, iyo baahida loo qabo muuqaallada bandhigga bannaanka iyo bannaanka ayaa si tartiib tartiib ah u soo baxaya.Baahida loo qabo muraayadaha iftiiminta sare ee soosaarayaasha mishiinada oo dhan ayaa si xawli ah u koraya, wakhtigan xaadirka ah, tirada ugu badan ee qeexida dhalaalka way adagtahay in la daboolo baahida suuqa.Waqtigaan, faa'iidooyinka alaabta shaashadda LED-ka ayaa la muujiyay.Shaashadaha LED-yada ma samayn karaan oo kaliya nidaamka bandhiga aag ballaaran oo aan lahayn cidhifyo cidhif ah, laakiin sidoo kale waxay ku habboon yihiin jawiga waaweyn iyo kuwa furan iyo daawashada fogaanta fog sababtoo ah mabda'a qiiqa tooska ah iyo sifooyinka qaabka isbeddelka ah ee alaabta shaashadda LED.
Dib u milicsiga taariikhda horumarinta ee shaashadaha waaweyn, way caddahay in waagii hore, suuqa kala-soocidda muraayadda weyni ay dhab ahaantii ahayd mid hooseeya.Waxa kaliya oo ay cusboonaysiisay oo ay beddeshay bandhigyada LCD-ga caadiga ah waxayna ku dabaqday suuqa kala qaybinta.Waxay leedahay dib u dhacyo badan, sida xallinta ku filnaansho la'aanta, oo ay ku adkaato buuxinta heerka loo baahan yahay, iyo xilliga qeexitaanka sare ee maanta, ma dabooli karto baahida suuqa.Bandhigyada LED-ku waxay leeyihiin faa'iidooyin dhammaystiran oo ku saabsan codsiyada dibadda, laakiin isla mar ahaantaana, tignoolajiyada bandhiga sida LCD iyo saadaalinta ayaa sidoo kale si degdeg ah u horumaray.Marka bandhigyada LED-ka ay ka tagaan codsiyada dibadda "weyn", waa maxay nooca horumarka ay ku yeelan karaan codsiyada "yar"?
Dagaalka Shaashada Weyn ee u dhexeeya LED iyo LCD
Xilligii qaraxa macluumaadka, waxaa soo badanaya codsiyo badan oo loogu talagalay kala qaybinta shaashadaha waaweyn, iyo warshadaha codsiga ayaa sidoo kale sii kordhaya.Laga soo bilaabo ilaalinta caadiga ah ee amniga dadweynaha, baahinta, iyo warshadaha gaadiidka ilaa tafaariiqda, ganacsiga, iyo warshadaha kale ee soo koraya, isugeynta ayaa lagu arki karaa meel kasta.Sababtoo ah suuqa oo aad u ballaaran iyo tartanka adag, midka ugu caansan waa tartanka u dhexeeya LED iyo LCD.Sanadihii la soo dhaafay, LCD splicing alaabta soo bandhigay iyobandhigyada LEDayaa si weyn loogu isticmaalay ilaalinta fiidyowga, taliska iyo diritaanka, iyaga oo ku tiirsan baahida weyn ee suuqa warshadaha amniga ee caalamiga ah.Badeecadaha soo bandhigay LCD kala-baxa waxay leeyihiin awood koritaan oo deggan.Marka la barbar dhigo LCD, bandhigyada LED ayaa aad u firfircoon.Ka faa'iidaysiga siyaasadaha iyo suuqa, bandhigyada LED waxay si tartiib tartiib ah uga guurayaan goobaha bandhigga xirfadeed sida amniga, gaadiidka, iyo tamarta una guuraan goobaha ganacsiga sida shineemooyinka iyo qolalka shirarka.Sida laga soo xigtay xogta, suuqa codsiga dibadda ee muraayadaha LED ee Shiinaha ayaa hadda xisaabiya 59%.Waayadan dambe, adeegsiga shaashadaha LED-ka ayaa sii kordhaya oo aad u baahsan, inta jeer ee ay iska horkeenaan LCD-ga ayaa sidoo kale sii kordhaya.Marka, waa maxay faa'iidooyinka muraayadaha bandhiga LED marka la barbar dhigo alaabada soo bandhigista LCD?
Kala fogaansho yar "hadda diiran" kor u kaca
Iyada oo horumarinta kala fogaanshaha yar yar, muraayadaha LED-yada ma aha oo kaliya ubaxyada dibadda, laakiin sidoo kale waxay ku jiraan qayb suuq ah oo suuqa ah ee bandhigyada ganacsiga gudaha sababtoo ah faa'iidooyinkooda.Sida laga soo xigtay xogta laga soo xigtay Akadeemiyada Ganacsiga iyo Warshadaha Shiinaha, dakhliga iibka ee muraayadaha yar yar ee LED-yada ee Shiinaha ayaa gaadhay 16.5 bilyan yuan sanadka 2022, waxaana la filayaa inuu kordho 18 bilyan yuan sanadka 2023. Sida laga soo xigtay xogta Luotu Technology, in rubuci hore ee 2023, adeegsiga bandhigyada LED-yada yar yar ee muuqaallada shirku waxay ahaayeen ku dhawaad kala badh, taasoo ka dhigan 46%.Dheefta codsiyada talisyada dhaqanka/korjoogteynta ayaa ahaa mid aad u sarreeya, saamiga suuqa ee aagga dhoofinta ayaa ka yar 20%.Dhab ahaantii, hadda, LED-yada yaryar ee tooska ah ee tooska ah waxay ku guuleysteen wax soo saar ballaaran oo P0.4 ah iyo alaabooyin ka sarreeya, waxayna horey u dhaafeen bandhigyada LCD ee tilmaamayaasha garoonka pixel.Marka la eego sahayda xallinta ee bandhigyada cabbirka weyn, waxay ku dhowaad dabooli karaan baahiyaha bandhig kasta.
Goobta bandhiga shaashadda weyn, alaabada kala fogaanshada yaryar waxay leeyihiin faa'iidooyin muuqda, saamiga suuqa ayaa la filayaa inuu sii wado inuu kordho.Themuraayad yar oo muraayad LED ahqaataa tignoolajiyada xakamaynta heerka dhibicda pixel si loo gaadho xakamaynta gobolka ee dhalaalka, soo celinta midabka, iyo labbiska unugga bandhigga.Marka la barbar dhigo ilaha iftiinka dambe ee soo jireenka ah, isha yar ee iftiinka dambe ee LED waxay leeyihiin tiro badan oo ah hirarka dhaadheer ee qiiqa, xawaaraha jawaabta degdega ah, iyo faa'iidooyin badan marka la barbar dhigo aaladaha soo bandhigida LED-ga caadiga ah.Isla mar ahaantaana, bandhigga weyn ee ganacsiga iyo goobaha isticmaalka guriga ayaa sidoo kale ah jihada gelitaanka fogaanta yar ee mustaqbalka, iyo soosaarayaasha waaweyni waxay si firfircoon ugu diyaargaroobaan suuqa bandhigga ganacsiga.Intaa waxaa dheer, horumarka degdega ah ee suuqa dhaqanka iyo dalxiiska ayaa sidoo kale keenay fursado badan oo codsi ah oo loogu talagalay bandhigyada LED ee goobta bandhigyada ganacsiga.Cusbooneysiinta moodooyinka hawlgalka ee meelo badan, oo ay ku jiraan filimada, xayaysiinta, ciyaaraha, iyo madadaalada, waxay sii waddaa inay horseedaan barwaaqada bandhigyada ganacsiga.Nidaamyada saadaasha, odoroska dhaqameedku had iyo jeer waxay wajahaan "dhalad dhalaaleed" iyo "xalinta xallinta" muraayadaha waaweyn.Labadan cilad farsamo ayaa si sax ah u ah faa'iidooyinka ugu weyn ee LED-yada garoonnada yaryar.Intaa waxaa dheer, iyadoo caannimada sii kordheysa ee HDR maanta, nidaamyada saadaasha mashruuca sidoo kale ma awoodaan inay gaaraan awoodda xakamaynta saxda ah ee shaashadda LED si loo gaaro "sub pixel by pixel" hagaajinta dhalaalka.Shaashadda muraayadda yar ee LED waxay gaari kartaa bandhig 8K ah, taas oo ka dhigaysa mid aad u xoog badan.
Marka la soo koobo, horumarinta bandhigyada LED-ka waa hab diiradda lagu saarayo bandhigyo khaas ah iyo sahaminta bandhigyada ganacsiga.Dhanka kale, habka horumarinta ee muraayadaha bandhiga LED-ka "weyn" ilaa "yar" iyo "yar" ilaa "micro", maxaa ku dhici doona muraayadaha LED-yada marka "weyn" uusan mar dambe noqonin faa'iido?
Ka guurista "B" una guurto "C" waxay weli u baahan tahay dadaal wadajir ah oo ka yimaada warshadaha soo bandhigista LED
Sanadihii la soo dhaafay, hoos u dhaca qiimaha iyo qiimaha, waxtarka-wax-ku-oolnimada ee bandhigyada yaryar ee LED-yada ayaa si isa soo taraysa u noqday mid caan ah, beddelaadkooda LCD ayaa sii xoogaystay.Bandhigyada LED-ka ayaa si tartiib tartiib ah uga balaadhay goobaha xirfadleyda ilaa aflaanta iyo guryaha guriga.Si loo sii wado, farqiga dhibcaha ee shaashadaha bandhiga LED ayaa si joogto ah hoos ugu dhacaya, horumarinta xagga qeexitaan sare iyo qeexitaan ultra sare, ku dadaalaya inay la tartamaan tignoolajiyada kale ee bandhigga iyo si joogto ah u dhex gala suuqa jira ee tignoolajiyada kale ee bandhigga.Si kastaba ha noqotee, isla mar ahaantaana, guusha ama guuldarada tignoolajiyada soo bandhigida sida LED iyo LCD ee codsiyada la taaban karo laguma go'aamiyo oo keliya tayada tignoolajiyada iyo alaabada.Xaaladda hadda jirta, sifooyinka farsamada ee muraayadaha LED-yada ayaa si joogto ah loo hagaajiyaa iyo alaabooyinka si joogto ah loo hagaajiyo.Si kastaba ha noqotee, isla mar ahaantaana, tignoolajiyada soo bandhigida saadaasha LCD waxay sidoo kale samaysay horumar degdeg ah, samaynta horumar la taaban karo ee muujinta midabka, xagasha muuqaalka, wakhtiga jawaabta, iyo dhinacyo kale.Marka la eego shaqeynta, waxay sidoo kale daboolay qaar ka mid ah faa'iidooyinka LED-ka.Nidaamkan tartanka ah, inkasta oo qiimaha muraayadaha bandhiga LED ay muujiyeen hoos u dhac, marka loo eego LCD iyo saadaalinta, waxay weli ku jiraan qiimo sare oo cirka ah.Shaashadaha LED-ka, waxaa weli jira caqabad ka horraysa in laga guuro "B" loona gudbo "C".Si loo jebiyo silsiladaha qiimaha, dhammaan warshadaha soo bandhiga LED waxay u baahan yihiin inay wada shaqeeyaan si horumar loo sameeyo.
Marka lagu daro jabinta caqabadaha qiimaha, arrin kale oo muhiim u ahShaashadda LED-kaAlaabooyinka laga guurayo B-dhamaadka loona gudbayo C-dhamaadka waa sida ugu wanaagsan ee loola tacaali karo baahida badeecada ee ku jirta macnaha cusboonaysiinta macaamiisha.Dib u milicsiga taariikhda horumarka ee muraayadaha TV-ga, laga bilaabo tignoolajiyada CRT ilaa teknolojiyadda LCD iyo OLED, iyo hadda teknoolojiyadda caanka ah ee Mini LED iyo Micro LED, guud ahaan, hal-abuurka warshadaha TV-ga waa mid gaabis ah, laakiin hal-abuur kasta oo tignoolajiyadeed wuxuu keenaa saamayn carqaladayn.Marka la barbar dhigo LCD, Micro LED weli ma gaarin wax soo saar ballaaran oo ku yaal garoonka guddiga TV-ga sababtoo ah qiimaha sarreeya.Waqtigan xaadirka ah, sida loo wanaajiyo waxqabadka iyo tartanka qiimaha ee shaashadaha LED-yada oo leh tilmaamayaasha kala fogaanshaha jira, si loo helo suuq weyn, waxay noqotay hawl aasaasi u ah shirkadaha warshadaha.Hagaajinta geeddi-socodka wax-soo-saarka ballaaran, tijaabinta qaababka cusub ee baakadaha, qaadashada chips-yar/yar-yar oo LED ah, iyo korodhka miisaanka iyo sirdoonka wax-soo-saarka ayaa dhamaantood noqday xulasho.Qaab dhismeedkan tartanku wuxuu aad ugu habboon yahay ballaarinta suuqa macaamiisha ee warshadaha, oo leh tignoolajiyada badan iyo diiradda saaraya dhimista qiimaha, taas oo sidoo kale kor u qaadi karta kobaca dheeraadka ah ee cabbirka suuqa warshadaha LED-ka.
Isbeddellada muuqaalka mustaqbalka weli lama garanayo, laakiin xilligan xaadirka ah ee badeecadaha kala duwan ee bandhigyada iyo u tartamaya aragtida macaamiisha, guud ahaan warshadaha bandhigga LED weli waxay u baahan yihiin in la sii baadho: waa maxay sifooyinka kale ee LED-ku soo bandhigaan alaabooyinka si fiican u furi kara suuqa qoyska. leeyihiin?Sideen u wajahnaa suuqa macaamiisha?Soosaarayaasha shaashadda LED-ka, marka lagu daro garashada faa'iidooyinka teknoolojiyada, waxay sidoo kale u baahan karaan inay tixgeliyaan fidinta iyo ballaarinta meelo badan.
