Ngo-2020, impembelelo yobhubhane izise ukuguquguquka okukhulu kunye nokothuka kwishishini LED ukubonisa . Kwisiqingatha sesibini sika-2020, amaxabiso enyuke yonke indlela. Emva kweminyaka emininzi, wonke umntu ebesecaleni kweprojekthi. Emva kokuqala konyaka, baya kuqhubeka benyuka. Le yimeko engazange ibonwe kule minyaka ilishumi idlulileyo. Ngoko kwakutheni ukuze kuvele le meko? Makhe ndimamele umhleli ngamnye!
Okokuqala, makhe sijonge imeko kwicala le-RGB elikhupha ukukhanya. Ukuchatshazelwa ngubhubhane, izinga lokusetyenziswa kwabavelisi be-chip ye-RGB kwisiqingatha sokuqala sonyaka ophelileyo lehle kakhulu kwaye imveliso yehla; kwisiqingatha sesibini sonyaka, uchatshazelwa kukunqongophala kweemarike zehlabathi kunye nokubuyiswa ngamandla kwemarike yasekhaya, ngenxa yentsikelelo efihliweyo, uluhlu lweempahla lwaye lwacinywa, luphela unyaka wesibini olandelelanayo wokukhula okungalunganga.
Nangona kunjalo, ngenxa yokuhla kwexabiso eliqhubekayo, inzuzo enkulu yabavelisi be-chip ye-RGB yokuthengisa i-chip incinci, kwaye abavelisi abanawo amandla aneleyo okwandisa ukuveliswa kweetshiphu ze-RGB. Izalathiso eziphambili zokwandiswa zibekwe kwiimarike ezivelayo ezifana ne-ultraviolet enzulu, i-sensor chips, i-GaN, kunye ne-Min / Micro chips. ulwalathiso. Ukongeza, iindleko zezinto eziluhlaza ziye zaqhubeka zinyuka kwiinyanga ezintandathu ezizayo, kwaye abavelisi be-chip bajongene noxinzelelo olukhulu lweendleko. Ke ngoko, kwixesha elifutshane, iitshiphusi zeRGB ziya kujongana nokunyuka kwexabiso okuncinci kunye nokubonelela okungqongqo.
Izibane zezibane
Okokuqala, abavelisi bezixhobo zokupakisha ezifana noomatshini bokudibanisa i-die-bonding, oomatshini bokudibanisa ucingo, kunye neeteyiphu ze-spectroscopic bajongene nokungonelanga kwezinto ezibonakalayo, ukunyuka kwamaxabiso okuqhubekayo, kunye nefuthe lokwandiswa okukhulu kwezinye iipakethe ze-semiconductor kwisixhobo. imfuno. Umthamo wokuhanjiswa kunye nomjikelo wokuhanjiswa kwezixhobo zokupakisha kuchaphazeleke kakhulu. Ngenxa yezithintelo, izicwangciso zokwandisa abavelisi bokupakisha zivaliwe, kwaye kunzima ukufezekisa ukwandiswa okukhulu kwisiqingatha sokuqala salo nyaka. Ke ngoko, amandla okuvelisa izixhobo zokupakishwa kwe-RGB kwisiqingatha sokuqala sonyaka kulindeleke ukuba afane naloo nto ekupheleni konyaka ophelileyo, kwaye ayiyi kunyuka kakhulu.
Impembelelo yobhubhane ekubuyeni ekhaya kunye nokungafuni ukuya emsebenzini yinto yexesha elide. Kusenzima ukukhangela abasebenzi kumgca wemveliso, kwaye izinga lokusetyenziswa kwabavelisi bokupakisha aliyi kunyuka kakhulu ukusuka ekupheleni konyaka ophelileyo. Ngokuthandwa ngakumbi kweepitshi ezincinci kwimarike yetheminali kunye nokuguqulwa okuqhubekayo kwamachaphaza ukuya kwiipatshi ezincinci, imfuno yamaso yesibane iya kunyuka. Ngexesha elifutshane, ukubonelelwa ngamaso ezibane ezipakishwe kwi-RGB kusenokuhlala kuqinile.
Kwelinye icala, amaxabiso zesinyithi non-ayoni, substrates PCB, iitshiphusi kunye nezinye izinto ekrwada ziye zaqhubeka ukunyuka, nto leyo ekhokelela ukunyuka okuqhubekayo kwiindleko imveliso yezityalo ukupakisha, kunye nabavelisi ukupakisha bajongene noxinzelelo lweendleko ezinkulu. Phantsi kwemiba emibini yokunyanzelwa komthamo kunye nokunyuka kweendleko zemathiriyeli ekrwada, abavelisi bokupakisha baya kulungelelanisa ulwabiwo lwamandla emveliso kwiindidi zemveliso ngokotshintsho kwimfuno yemarike kunye notshintsho kulwakhiwo lweendleko zabo. Ngelixa umthamo wemveliso uwonke uhleli ungatshintshi, ukwandisa umthamo wemveliso yeemveliso ezinomda ophezulu ngelixa unciphisa umthamo wemveliso yeemveliso ezinengeniso ephantsi. Oku kuya kukhokelela kukungalingani ngokwezigaba phakathi konikezelo kunye nemfuno yeendidi ezahlukeneyo zeemveliso, oko kukuthi, ezinye iindidi ziphelile kwixesha elithile, kwaye ezinye iindidi azikho kwimpahla. Ukungalingani ngokwezigaba konikezelo kunye nemfuno kuya kuzisa ukuhla kwamaxabiso, kunye nokuguquguquka okwahluka kunye noluhlu. Ngoko ke, kwixesha elifutshane, ixabiso leentsimbi zesibane se-RGB liyahluka ngokuhambelana nabavelisi abahlukeneyo, iindidi, kunye neemodeli, kwaye ixabiso lexabiso liya kwahluka. Nangona kunjalo, ngokuxhomekeke kumthamo wemveliso kunye neemeko zeendleko, ngokubanzi, ixabiso lexabiso leentsimbi zesibane se-RGB akunakwenzeka ukuba libe nokuhla ngokupheleleyo, kwaye iinkcukacha zomntu ngamnye zinokuqhubeka nokunyuka kancinci. Uloyiko lwengqondo "lokuthenga kufutshane nokungathengi ngaphezulu, ukuthenga ukunyuka kwaye ungathengi ukwehla" kuya kwandisa ukunqongophala kunye nokulindela ukunyuka kwamaxabiso. Abavelisi bokubonisa abasezantsi baya kuphakamisa umgangatho "we-inventory yokhuseleko" kunye nokwandisa ukuthengwa kwezinto ezithengiswayo, okuya kwandisa ngakumbi inqanaba Ukunikezelwa kwezesondo kuqinile.
Ngokucacileyo, oku "kukuthenga kwangaphambili okuphakathi" koluhlu lwempahla ekrwada. Ukonyuka kwabavelisi bemiboniso esezantsi, ukunyuka kwe-inventory yemathiriyeli ekrwada, i-semi-indleko, kunye ne-inventri yemveliso egqityiweyo, kufuneka igaywe kwaye icocwe yimarike ye-terminal. Ukuba imakethi yetheminali elandelayo ingaphantsi kunoko bekulindelekile, idibana nobuthathaka okanye ukukhula okucothayo, iya kuchaphazela isikali esilandelayo sokuthengwa kwemathiriyeli ekrwada kunye nesingqi sokuthengwa kwabavelisi bomboniso, kwaye iya kuba neempembelelo ezintsha kubume obukhuphisanayo kunye nentsingiselo yabavelisi bokupakisha abalandelayo. Ukusuka kwimbono yokupakisha izixhobo zokuvelisa izixhobo zangoku kunye nezicwangciso zokwandisa ezilandelayo, ekuhambeni kwexesha, imeko yonke yokugqithiswa ayitshintshanga, kwaye ukunqongophala kwangoku kukungalingani kwezigaba zokubonelela kunye nemfuno.
Umqhubi we-IC, inkqubo yokulawula, i-PCB
Ukunqongophala kwehlabathi jikelele kwee-wafers kunye nokucudiswa kwe-semiconductor ukupakisha umthamo we-Foundry ngamanye amashishini akukhokelela ekuboneleleni okuqinileyo komqhubi we-ICs kunye nokunyuka kwexabiso, kodwa kukhokelela kwiitshiphusi zeFPGA, iitshiphusi zememori, iichips zevidiyo. , Iitshiphu zonxibelelwano, iitshiphusi zolawulo lwamandla, njl. njl Oku kuya kuzisa uxinzelelo ekunikezelweni kwezinto eziluhlaza kunye nokunyuka kweendleko zokuqhuba i-IC kunye nabavelisi benkqubo yokulawula. Ixabiso PCB izinto ekrwada unyukile kunye nomthamo imveliso iye yacudiswa ngamanye amashishini, okubangele unikezelo PCB tight kunye nokunyuka kwamaxabiso, nto leyo eya kuchaphazela imboni yokubonisa LED kwixesha elide noko.
Kuyafaneleka ukuba uqaphele ukuba ukunqongophala kunye nokunyuka kwexabiso lomqhubi we-ICs kunye ne-PCBs zihluke ekunqongopheni kwee-chips ze-RGB, amaso ezibane ezipakishweyo, kunye nomthombo kunye nokulawulwa kokunyuka kwexabiso. Eyangaphambili ichatshazelwa lutshintsho kwimeko yemarike yehlabathi kwaye umthamo wemveliso ucudiswa ngamanye amashishini. Ulawulo lwemboniselo ye-LED kunye nolawulo lubuthathaka. Nangona kunjalo, ngenxa yokuba imfuno ye-ICs okanye i-PCB yomqhubi we-LED ifakwe kulwandle olukhulu lwemboni ye-semiconductor yehlabathi, isikali ngokwenene "sincinci kwaye sincinci kakhulu", kwaye amaconsi ambalwa amanzi anele. Okoko nje abavelisi abafanelekileyo becwangcisa kakuhle, bajongana nobudlelwane bomthengisi, bahlukanise imingcipheko yababoneleli, kwaye balawule umjikelo wokugcinwa kwempahla kunye nokhuseleko lwesitokhwe sezinto eziphambili, ukunqongophala okwethutyana, kwaye isithuba asiyi kuba sikhulu kakhulu. Le yokugqibela ibangelwa ikakhulu lubonelelo lwe-LED lweshishini ngokwamanqanaba kunye nokungalingani kwemfuno kunye nokugcwala koloyiko. Nangona ikwachatshazelwa yimeko-bume yemarike enkulu (efana nokunqongophala kweentsimbi ezingezizo i-ferrous kunye nezinye izinto ezininzi zorhwebo, ukunyuka kwamaxabiso, njl.njl.), ubonelelo lweshishini kunye nobudlelwane bemfuno Ekugqibeleni liya kuzilawula ngokwalo.
Isikrini sokubonisa
Impembelelo yokunqongophala kunye nokunyuka kwexabiso lezinto eziluhlaza ezifana neetshiphusi, amaso ezibane ezipakishweyo, ii-ICs zomqhubi, kunye nee-PCBs kukhuphiswano lomhlaba lwabavelisi bemiboniso akuphelelanga "ekunqongophelweni" kunye "nokwanda." Enye into ebalulekileyo echaphazela ubudlelwane obukhuphisanayo yile: "ngaphandle kokulungelelaniswa, ulungelelwaniso olwahlukileyo." Ukuba awukho sync, uya konyuswa kwixabiso kuqala, akunyanzelekanga ukuba abanye banyuswe ngaxeshanye; ukuba umthengisi wakho ulinyusile ixabiso, isenokungabi kukonyuka kwexabiso kubaboneleli babanye abantu; ukuba uphelelwe sisitokhwe kuqala, kusenokunganyanzelekanga ukuba abanye babe ngaxeshanye Azisekho; umthengisi wakho uphelelwe sisitokhwe, akunyanzelekanga ukuba ababoneleli babanye nabo baphelelwe sisitokhwe. Kwimilinganiselo eyahlukeneyo, ukuba unyuswe nge-20%, abanye banokunyuka kuphela nge-5%; ukuba uphelelwe sisitokhwe nge-60%, abanye banokuba mfutshane kuphela nge-10%. "Umahluko wexesha" kunye "nomthamo wobungakanani" uye wandisa uthelekiso lokhuphiswano.
Okubaluleke ngakumbi, kubavelisi bomboniso, akusiyo nje indleko emisela ixabiso lomboniso. Nangona abanikezeli abaphezulu benyuse amaxabiso kwizinga elikhulu kwaye bandise ixabiso le-BOM lokubonisa, ixabiso lokugqibela lokubonisa kwimarike lichongwa yimfuno kunye nokhuphiswano. Ngokukodwa, ukunyuka okulindelweyo kokunqongophala kokubonelela kuye kwaphakamisa izinga lokhuseleko lwamashishini, nto leyo ibeka uxinzelelo olukhulu kwiintengiso zeemarike. Ukuba umthamo wentengiso yemarike awufikeleli kulindelo lwenkampani kwaye isixa esikhulu se-inventri sisemva, isiphumo sinokuncitshiswa kwengeniso (okanye kwanelahleko), impembelelo yexabiso eliphantsi, ukwetyiswa koluhlu lweempahla, kunye nokurhoxiswa kwemali. Ke ngoko, impembelelo yokunqongophala kwezinto kunye nokunyuka kwexabiso kwifektri yesikrini ayizisi isiphumo esingenakuphepheka sokunyuka kwexabiso. Ngexesha lexesha, ixabiso lesikrini sokubonisa linokuthi lihla linyuka ngokweenkcazo ezahlukeneyo kunye neemodeli, kunye nabavelisi abahlukeneyo.
Omnye umba ofanele ukuqwalaselwa ngumgangatho. Ngenxa yokungalingani okwenziwa ngamanqanaba okubonelela kunye nemfuno, kukhatshwa kukothuka, izinto aziyi kuba naxhala malunga nokuthengisa, okuya kubangela ukuba iinkampani ezizimeleyo ziphumle kulawulo lwezinto ezingenayo kunye nomgangatho, okukhokelela kumngcipheko womgangatho.
Imeko enzima kunye neyoyikekayo yokhuphiswano ibeke phambili iimfuno eziphezulu kunye eziphezulu zokusebenza kunye namandla okulawula iinkampani zokubonisa. Ababoneleli ngengqiqo baya kunika ingqwalaselo ephambili ekuqinisekiseni unikezelo lwabathengi abaphambili kunye nabathengi abaphambili, kwaye izixhobo zokubonelela ziya kugxilwa kwiinkampani eziphambili. Phakathi kwamashishini, ngeli xesha lingaqhelekanga, uvavanyo luyanda nangakumbi lusebenza ngokubanzi kunye nobuchule bolawulo lwamashishini afana nesakhono sothungelwano lwezibonelelo, amandla okuthengisa, kunye nesakhono sokulawula umgangatho. Ke ngoko, sikholelwa ukuba uhlenga-hlengiso lweshishini luya kuqina ngakumbi.
Abasasazi, iikontraka kunye nabahlanganisi
Kubasasazi basekhaya, iinkampani zobunjineli, kunye nabadibanisi, abajongene nemeko yentengiso entsonkothileyo neguqukayo, kufuneka balumke ngakumbi ekukhetheni abathengisi abangamahlakani. Abavelisi abanezikali ezinkulu, amanani amakhulu okuthenga, kunye nentlawulo ethembekileyo yokuthenga baya kuxhaswa ngamakhonkco angcono okubonelela kwaye baya kukhuphisana ngakumbi kwimarike. Ngexesha elifanayo, ngenxa yokunikezelwa okuqinileyo kwekhonkco loshishino lonke, nokuba ngaba abavelisi bentsebenziswano banokunikezela ngexesha elifanelekileyo liya kuba yinto ebalulekileyo yokuhlola amandla abavelisi bentsebenziswano.
Isishwankathelo, okokuqala, kufuneka sithintele umngcipheko wokuba umhla wokunikezelwa othenjisiweyo awukwazi ukuzaliseka; okwesibini, simele siwuthintele umngcipheko wokuba ixabiso elithenjisiweyo alinakuzaliseka; okwesithathu, kufuneka sithintele ukugcinwa ngokufihlakeleyo kwempahla kunye nomngcipheko wokuhla kwexabiso lemarike; okwesine, kufuneka sithintele imingcipheko esemgangathweni. Abo bavelisi banenkqubo epheleleyo yexabiso kunye nolawulo lwamaxabiso, ukukhuselwa kohlengahlengiso lwexabiso, ulawulo lomgangatho, kunye nezibophelelo zokuhanjiswa baya kufumana inkxaso eyongezelelweyo kunye nokuxhomekeka kubathengisi, iinjineli kunye nabahlanganisi.
Umboniso wentengiso yesiphelo
Uthintelo lwendyikityha yasekhaya luphinde lwamelana novavanyo “loMnyhadala waseNtwasahlobo”. Kulindeleke ukuba imakethi yokubonisa yasekhaya iza kungena kumjikelo wentengiso oqhelekileyo, kodwa kusekho inqanaba elithile lokungaqiniseki malunga nokukhula kwayo. Ezi seshini zimbini azikabizwa, kwaye nohlahlo lwabiwo mali lukarhulumente walo nyaka alukamiselwa. Impembelelo yokuqhelaniswa nomgaqo-nkqubo omkhulu kushishino kusafuneka iqwalaselwe.
Ngokwembono yesicelo soshishino kunye nokuveliswa kwemveliso yesiboniso ngokwaso, kubonakala ngathi akukho ntengiso enkulu entsha eyongezelelweyo. Yintoni eqinisekileyo kukuba i-pitches encinci iya kukhawulezisa ukuthandwa, i-dot pitches iya kutshintshela kwiindawo ezincinci, kwaye imarike eneepakethi ezingaphezulu kwe-P1.25 (ibandakanyiwe) iya kujika kwimarike yesitishi ngendlela ejikelezayo. Izinga lokukhula kweemarike ngaphantsi kwe-P1.0 aliyi kuba phezulu kakhulu kwixesha elifutshane. ngokukhawuleza. Kuya kufuneka kuliwe iimfazwe zamaxabiso. Undoqo wemfazwe yexabiso ayinyanzelekanga ukuba unciphise amaxabiso, kodwa "ukuvula ukusasazeka okwaneleyo" kwaye ngokuqhelekileyo ukwandisa amaxabiso. Ukuba andithanga ndande, ikwayimfazwe yamaxabiso.
Kwiimarike zaphesheya, isiqingatha sokuqala sonyaka besingekho nje, kwaye asizukuphucula kakhulu ukusuka ekupheleni konyaka ophelileyo. Akukho mfuneko yokulindela lukhulu ekuxhomekekeni kwizitofu zokugonya ukulawula ukusasazeka kobhubhane wehlabathi ngexesha elifutshane. Incwadi ethi “The Essence of Poverty” ithetha ngeminyaka yobunzima kunye nobunzima ekuhlangabezwene nayo ekwandiseni ugonyo lwabantwana lwerhashalala kwihlabathi jikelele, lufikelele kuma-70%. Izinga lokugonywa kwabantu abangentla apha ayisiyonto ilula (njengoko kubhaliwe, ugonyo lwasekhaya lufikelele kuphela kwi-31 yezigidi zeedosi). Ngaphezu koko, ukuza kuthi ga ngoku, akukho lwazi lugunyazisiweyo lusixelela ukuba isitofu sokugonya sinokusebenza ixesha elingakanani. Ukuba imarike ye-terminal yokubonisa ihlupheka ngenxa yobuthathaka kunye nokukhula okucothayo kwisiqingatha sokuqala sonyaka, ukunqongophala okunyukayo kuya kuncitshiswa, ukunyuka kwamaxabiso kuya kunyanzeliswa, kwaye iimfazwe zexabiso ziya kuqina.
Ukongeza kwipatheni esisiseko ekhankanywe ngasentla, intsingiselo, kunye neendlela zamacandelo aphambili kwikhonkco loshishino, kukho abahlobo abaninzi abaxhalabileyo malunga neemarike ezihlukeneyo, ezifana ne-COB, N ku-1, inkomfa yonke-inye, ngaphandle isithuba esincinci esincinci, njl., ngenxa yendawo encinci , Ayichazwanga nganye nganye, kunye nabahlobo abanomdla bamkelekile ukuba baqhagamshelane kwaye baxoxe ngokwahlukeneyo.
Ngamafutshane, imakethi ngo-2021 iya kujongana nokungaqiniseki kunye nokuguquguquka okukhulu xa kuthelekiswa neminyaka edlulileyo. I-Wandaping 52DP.COM iya kuqhubeka inikela ingqalelo kuphuhliso kunye notshintsho lwekhonkco loshishino lonke kunye nemarike, kwaye ikunike ulwazi lwemarike, uhlalutyo lweshishini kunye nethemba lokuhamba.
