Zizindikiro zinayi zazikulu za chiwonetsero cha LED:

Chiwonetsero cha LED chakunja cha P10

1. Kuwala kwambiri

Palibe chodziwikiratu chofunikira pakuchita kofunikira kwa "kuwala kwakukulu".Chifukwa malo ogwiritsira ntchito zowonetsera ma LED ndi osiyana kwambiri, kuwala (ndiko, kuwala kozungulira komwe anthu wamba amatcha) ndi kosiyana.Chifukwa chake, pazinthu zovuta zambiri, bola ngati njira zoyeserera zofananira zafotokozedwa muyeso, wopereka amapereka chidziwitso cha magwiridwe antchito.Mndandanda (zachidziwitso chazinthu) ndi wabwinoko kuposa zomwe zimaperekedwa mulingo.Zonsezi zikugwirizana ndi miyezo yapadziko lonse, koma izi zimabweretsanso kufananitsa kopanda phindu pa malonda, ndipo ogwiritsa ntchito samamvetsetsa izi, kotero kuti "kuwala kwakukulu" komwe kumafunika m'mabuku ambiri opangira ndalama nthawi zambiri kumakhala kokwera kwambiri kuposa kufunikira kwenikweni.Chifukwa chake, tikulimbikitsidwa kuti tiwongolere ogwiritsa ntchito kuti amvetsetse bwino kalozera wa "kuwala kwakukulu" kwa chiwonetsero cha LED, ndikofunikira kuti makampani apereke chiwongolero: nthawi zina, m'malo owunikira osiyanasiyana, kuwala kwa chiwonetsero cha LED kumafika pamtengo wina.akhoza kukwaniritsa zofunikira.

2. Cholakwika chachikulu cha mtundu wavelength

Sinthani mtundu woyambira wavelength error index kuchokera ku "primary color wavelength error" kukhala "primary color dominant wavelength error", zomwe zitha kufotokozera bwino zomwe chizindikirochi chikuwonetsa pa chiwonetsero cha LED.Utali wopambana wa mtundu ndi wofanana ndi mtundu wa mtundu womwe umawonedwa ndi diso la munthu, womwe ndi kuchuluka kwamalingaliro ndi chikhalidwe chomwe chimasiyanitsa mitundu kwa wina ndi mnzake.Zofunikira pakuchita zomwe zafotokozedwa ndi mulingo wamakampaniwa, kwenikweni, ogwiritsa ntchito sangathe kumvetsetsa kuti ndi chizindikiro chomwe chimawonetsa mawonekedwe amtundu wa chiwonetsero cha LED.Chifukwa chake, kodi tiyenera kuwongolera ogwiritsa ntchito kuti amvetsetse mawuwo poyamba, kenako ndikumvetsetsa chizindikirochi?Kapena kodi tiyenera kuzindikira kaye ndikumvetsetsa chiwonetsero cha LED kuchokera kumalingaliro a kasitomala, ndikupereka mawonekedwe osavuta kumva omwe ogwiritsa ntchito angamvetse?

Imodzi mwa mfundo za kamangidwe ka miyezo ya malonda ndi "Mfundo Yoyendetsera Ntchito": "Kufikira momwe kungathekere, zofunikira ziyenera kufotokozedwa ndi mawonekedwe a kagwiridwe ka ntchito m'malo mwa mapangidwe ndi mafotokozedwe, ndipo njirayi imasiya mwayi waukulu kwambiri wa chitukuko chaukadaulo.""Wavelength error" ndizofunikira pakupanga.Ngati asinthidwa ndi "kufanana kwamtundu", palibe LED yokhala ndi kutalika kwanthawi yayitali.Kwa ogwiritsa ntchito, bola ngati muwonetsetsa kuti mtundu wa chiwonetsero cha LED ndi yunifolomu, simuyenera kuganizira ngati mumagwiritsa ntchito Njira zaukadaulo kuti mukwaniritse, kusiya malo ochulukirapo momwe mungathere kuti chitukuko chaukadaulo, chomwe chili chopindulitsa kwambiri chitukuko cha makampani.

3. Ntchito yozungulira

Mofanana ndi "Mfundo Yoyendetsera Ntchito" yomwe yatchulidwa pamwambapa, "M'mene tingathere, zofunikira ziyenera kufotokozedwa ndi mawonekedwe a kachitidwe m'malo mwa mapangidwe ndi mafotokozedwe, ndipo njirayi imasiya mwayi waukulu wa chitukuko chaukadaulo".Timakhulupilira kuti "kukhala "Ratio" ndikofunika kokha kwa teknoloji yojambula ndipo sikuyenera kugwiritsidwa ntchito ngati chisonyezero cha machitidwe owonetsera LED;tonse tikudziwa kuti wogwiritsa ntchito aliyense amene amasamala za kayendetsedwe kake kawonekedwe ka skrini, amasamala za momwe chiwonetserochi chikuyendera, m'malo mogwiritsa ntchito luso lathu;chifukwa chiyani timapanga zotchinga zaukadaulo zotere kuti tichepetse chitukuko chaukadaulo wamakampani?

4. Mlingo wotsitsimutsa

Kuchokera pakuwona njira zoyezera, zikuwoneka kuti sizikunyalanyaza zovuta zenizeni za ogwiritsa ntchito, komanso siziganiziranso ma IC osiyanasiyana oyendetsa, kuyendetsa mabwalo ndi njira zomwe zimagwiritsidwa ntchito ndi opanga osiyanasiyana, zomwe zimapangitsa kuti pakhale zovuta pakuyesa.Mwachitsanzo, kuyitanitsa kwamtundu wamtundu wa Shenzhen Stadium, pachiyeso cha akatswiri, mayeso a chizindikirochi amabweretsa mavuto ambiri."Kutsitsimutsa pafupipafupi" ndikofanana ndi nthawi yomwe imafunika kuwonetsa mawonekedwe a chinsalu, ndipo chinsalu chowonetsera chimatengedwa ngati gwero la kuwala, ndiko kuti, kusinthasintha kwa gwero la kuwala.Titha kuyesa mwachindunji kuthwanima kwa gwero la kuwala kwa chinsalu chowonetsera ndi chida chofanana ndi "photosensitive frequency mita" kuti tiwonetse chizindikiro ichi.Tachita mayesowa pogwiritsa ntchito oscilloscope kuyeza mawonekedwe amtundu wamtundu wa LED pamtundu uliwonse kuti tidziwe "ma frequency otsitsimula", omwe ndi 200Hz pansi pa malo oyera;Pansi pamiyezo yotsika imvi monga 3-level imvi, ma frequency omwe amayezedwa amakhala okwera ngati 200Hz.Zoposa khumi k Hz, ndi kuyeza ndi PR-650 spectrometer;Ziribe kanthu kumunda koyera kapena mulingo wotuwa wa 200, 100, 50, ndi zina zotero, kufiyira pafupipafupi kwa gwero loyezera ndi 200 Hz.

Chiwonetsero chowongolera chowoneka ngati mbiya yavinyo ku Zhongshan, China

Mfundo zomwe zili pamwambazi ndikungofotokozera mwachidule za maonekedwe a ma LED angapo.Palinso "moyo wogwira ntchito", "nthawi yokwanira pakati pa zolephera", ndi zina zambiri zomwe zimakumana ndi kuyitanitsa.Palibe njira yoyesera yomwe ingagwiritsidwe ntchito pakanthawi kochepa.Nthawi yotsimikizira ngati chiwonetsero cha LED chikukwaniritsa zofunikira zakukhazikika, kudalirika kapena moyo;zofunika izi siziyenera kufotokozedwa.Wopanga akhoza kupanga chitsimikizo, koma sichingalowe m'malo mwake.Ndi lingaliro la bizinesi, lingaliro la mgwirizano, osati lingaliro laukadaulo.Makampaniwa ayenera kukhala ndi mawu omveka bwino pa izi, zomwe zidzakhala zopindulitsa kwambiri kwa ogwiritsa ntchito, opanga ndi makampani onse.

Ponena za momwe angawatsogolere ogwiritsa ntchito kuti amvetsetse bwino zomwe zimapangidwa ndi dongosolo lovuta kwambiri monga chiwonetsero cha LED, ndikofunikirabe kuti mabungwe amakampani azigwira mabwalo aukadaulo owonetsera ma LED, ndikuwunika izi kuchokera pakuwona kwa ogwiritsa ntchito ndikuwongolera ogwiritsa ntchito molondola. kuzindikira mawonekedwe a LED..
