Iimpawu ezine eziphambili zomboniso okhokelayo:

I-P10 yangaphandle ekhokelela umboniso

1. Ukukhanya okuphezulu

Akukho mfuneko yeempawu ezicacileyo zentsebenzo ebalulekileyo "yokukhanya okukhulu". Ngenxa yokuba indawo yokusetyenziswa kwezikrini zokubonisa i-LED yahluke kakhulu, ukukhanya (oko kukuthi, ukukhanya okubonakalayo abantu abaqhelekileyo ababizayo) kwahlukile. Ke ngoko, uninzi lweemveliso ezintsonkothileyo, nje ukuba iindlela zovavanyo ezihambelanayo zichazwe kumgangatho, umthengisi uya kubonelela ngedatha yokusebenza. Uluhlu (lwengcaciso yemveliso) lungcono kuneemfuno zokusebenza ezithile ezinikwe kumgangatho. Ezi zonke zihambelana nemigangatho yamazwe ngamazwe, kodwa oku kukhokelela ekuthelekiseni okungenangqiqo ekuthengisweni, kwaye abasebenzisi abayiqondi le nto, ukuze "ukukhanya okukhulu" okufunekayo kumaxwebhu amaninzi ebhidi kaninzi kuphezulu kakhulu kunesidingo sangempela. Ngoko ke, kucetyiswa ukuba ukuze ukhokele abasebenzisi ukuba baqonde ngokuchanekileyo isalathisi sokusebenza "sokukhanya okukhulu" kwesiboniso se-LED, kuyimfuneko ukuba imboni inike isikhokelo: kwezinye iimeko, kwindawo yokusetyenziswa kokukhanya okuhlukeneyo, ukukhanya komboniso we-LED kufikelela kwixabiso elithile. inokuhlangabezana neemfuno.

2. Impazamo yobude bobude obuphambili

Guqula isalathiso sempazamo yombala ophambili ukusuka "kwimpazamo yombala wewavelength" ukuya "kwimpazamo yombala ophambili wewavelength", enokuthi ichaze ngcono ukuba zeziphi iimpawu ezibonakaliswa ngulo mqondiso kumboniso we-LED. Ubude obuphezulu bombala bulingana ne-hue yombala obonwa liliso lomntu, ubuninzi bengqondo kunye nophawu olwahlula imibala komnye nomnye. Iimfuno zokusebenza ezichazwe ngulo mgangatho woshishino, ngokoqobo, abasebenzisi abanakuqonda ukuba sisalathisi esibonisa ukufana kombala wesiboniso se-LED. Ke ngoko, ngaba kufuneka sikhokele abasebenzisi ukuba baqonde igama kuqala, kwaye emva koko basiqonde esi salathisi? Okanye ngaba kufuneka siqale siqonde kwaye siqonde isiboniso se-LED ngokwembono yomthengi, kwaye emva koko sinike iimpawu zentsebenzo ekulula ukuziqonda ezinokuqondwa ngabasebenzisi?

Omnye wemigaqo ekuqulunqweni kwemigangatho yemveliso “NgumGaqo wokuSebenza”: “Kangangoko kunokwenzeka, iimfuno kufuneka zibonakaliswe ngeempawu zokusebenza kuneempawu zoyilo nenkcazo, kwaye le ndlela ishiya eyona ndlela ibalaseleyo yophuhliso lobuchwepheshe.” "Impazamo yeWavelength" iyimfuneko yoyilo olunjalo. Ukuba ifakwe endaweni "yombala ofanayo", akukho LED enobude obulinganiselweyo. Kubasebenzisi, okoko uqinisekisa ukuba umbala wesiboniso se-LED ufana, akufuneki ucinge ukuba uyayisebenzisa Yintoni indlela yobugcisa ukuphumeza, shiya indawo enkulu kangangoko kunokwenzeka kuphuhliso lwezobuchwepheshe, oluyinzuzo kakhulu uphuhliso loshishino.

3. Umjikelo womsebenzi

Kanye “njengomGaqo wokuSebenza” okhankanywe ngasentla, “Kangangoko kunokwenzeka, iimfuno kufuneka zibonakaliswe ngeempawu zokusebenza kuneempawu zoyilo kunye nenkcazo, kwaye le ndlela ishiya eyona ndlela yophuhliso lobuchwepheshe”. Sikholelwa ukuba "ukuhlala "I-Ratio" yinto efunekayo yobugcisa bokuyila kwaye akufanele isetyenziswe njengesalathisi sokusebenza kwemigangatho yemveliso yokubonisa i-LED; sonke siyazi ukuba nawuphi na umsebenzisi okhathalayo malunga nomjikelezo womsebenzi wokuqhuba kwesikrini sokubonisa, bayayikhathalela umphumo wesikrini sokubonisa , kunokuphunyezwa kwethu kobugcisa; kutheni sisenza imiqobo enjalo ngokwethu ukunciphisa uphuhliso lobuchwepheshe bolu shishino?

4. Ireyithi yokuhlaziya

Ukususela kumbono weendlela zokulinganisa, kubonakala kukungazinaki iinkxalabo zangempela zabasebenzisi, kwaye kwakhona ayithatheli ingqalelo kwii-ICs zokuqhuba ezahlukeneyo, iisekethe zokuqhuba kunye neendlela ezisetyenziswa ngabavelisi abahlukeneyo, okubangela ubunzima bokuvavanya. Ngokomzekelo, ibhidi yesikrini esigcwele umbala we-Shenzhen Stadium, kuvavanyo lwesampulu yeengcali, uvavanyo lwesi salathisi luzisa iingxaki ezininzi. "Ukuhlaziya i-frequency" yimvisiswano yexesha elifunekayo ukubonisa isakhelo sesikrini, kwaye isikrini sokubonisa sithathwa njengomthombo wokukhanya, oko kukuthi, ukujikeleza okujikelezayo komthombo wokukhanya. Sinokuvavanya ngokuthe ngqo ukujikeleza kokukhanya komthombo wokukhanya kwesikrini kunye nesixhobo esifana ne "photosensitive frequency meter" ukubonisa esi salathisi. Senze olu vavanyo sisebenzisa i-oscilloscope ukulinganisa i-LED drive waveform yangoku yawo nawuphi na umbala ukumisela "i-refresh frequency", eyi-200Hz phantsi kwebala elimhlophe; phantsi kwamanqanaba aphantsi angwevu afana ne-3-level grey, i-frequency elinganisiweyo iphezulu njenge-200Hz. Ngaphezu kweshumi kHz, kwaye ilinganiswe ne-PR-650 spectrometer; kungakhathaliseki ukuba kumhlaba omhlophe okanye kwinqanaba elingwevu le-200, i-100, i-50, njl., i-flicker frequency yomthombo wokukhanya olinganisiweyo yi-200 Hz.

Umboniso okhokelayo omile okwebhere yewayini eZhongshan, eTshayina

Ezi ngongoma zingasentla ziyinkcazo emfutshane nje yeempawu zemiboniso emininzi ye-LED. Kukho ezininzi "ubomi bokusebenza", "ixesha eliqhelekileyo phakathi kweentsilelo", njl njl. Akukho ndlela yokuvavanya enokusetyenziswa ngexesha elifutshane. Ixesha lokuqinisekisa ukuba isiboniso se-LED sihlangabezana neemfuno zokuzinza, ukuthembeka okanye ubomi; ezi mfuno akufuneki zichazwe. Umvelisi angenza isiqinisekiso, kodwa ayinakuthatha indawo yemfuneko. Yingcamango yeshishini, ingcamango yekhontrakthi, kungekhona ingcamango yobugcisa. Ishishini kufuneka libe nenkcazo ecacileyo kule nto, eya kuba luncedo kakhulu kubasebenzisi, abavelisi kunye noshishino ngokubanzi.

Ngokuphathelele indlela yokukhokela abasebenzisi ukuba baqonde ngokuchanekileyo imveliso yenkqubo entsonkothileyo njengomboniso we-LED, kusafuneka ukuba imibutho yoshishino ibambe ngakumbi iiforam zetekhnoloji zokubonisa i-LED, kunye nokuhlalutya le mveliso ngokwembono yabasebenzisi kunye nokukhokela abasebenzisi ngokuchanekileyo. ukuqonda umboniso we-LED. .
