1. Izinga lokwehluleka

Njengoba isibonisi se-LED esinombala ogcwele sakhiwe amashumi ezinkulungwane noma amakhulu ezinkulungwane zamaphikseli ahlanganiswe ama-LED amathathu abomvu, aluhlaza, naluhlaza okwesibhakabhaka, ukwehluleka kwanoma yimuphi umbala we-LED kuzothinta wonke umphumela wokubuka wesibonisi.Ngokuvamile, ngokwesipiliyoni sembonini, izinga lokuhluleka kwesibonisi se-LED esinemibala egcwele kusukela ekuqaleni kokuhlanganiswa kuya emahoreni angu-72 okuguga ngaphambi kokuthunyelwa akufanele kube ngaphezu kwezinkulungwane ezintathu eziyishumi (kubhekiselwa ekuhlulekeni okubangelwa idivayisi ye-LED ngokwayo) .

2. Ikhono le-Antistatic

I-LED iyithuluzi le-semiconductor, elizwela kugesi omile futhi lingabangela ukwehluleka kokuma kalula.Ngakho-ke, ikhono le-anti-static libaluleke kakhulu empilweni yesikrini sokubonisa.Ngokuvamile, i-voltage yokuhluleka yokuhlolwa kwemodi ye-electrostatic yomzimba womuntu ye-LED akufanele ibe ngaphansi kuka-2000V.

3. Izici zokunciphisa

Ama-LED abomvu, aluhlaza, naluhlaza okwesibhakabhaka wonke anezici zokuncisha ukukhanya njengoba isikhathi sokusebenza sikhula.Ikhwalithi yama-chips e-LED, ikhwalithi yezinto ezisizayo kanye nezinga lobuchwepheshe bokupakisha inquma isivinini sokuncisha ama-LED.Ngokuvamile, ngemva kwamahora angu-1000, ukuhlolwa kokukhanya kwezinga lokushisa okujwayelekile okungu-20 mA, ukuncishiswa kwe-LED ebomvu kufanele kube ngaphansi kuka-10%, futhi ukufiphala kwama-LED aluhlaza okwesibhakabhaka nokuluhlaza kufanele kube ngaphansi kuka-15%.Ukufana kokuncishiswa okubomvu, okuluhlaza okotshani, nokuluhlaza kunomthelela omkhulu kubhalansi emhlophe yesibonisi se-LED esinombala ogcwele ngokuzayo, okuphinde kuthinte ukuthembeka kwesibonisi sesibonisi.

4. Ukugqama

Ukukhanya kwe-LED kuyisici esibalulekile sokukhanya kwesibonisi.Uma iphezulu ukukhanya kwe-LED, iba nkulu imajini yokusetshenziswa yamanje, elungele ukonga amandla nokugcina i-LED izinzile.Ama-LED anamanani ahlukene e-engeli.Uma ukukhanya kwe-chip kulungisiwe, i-engeli encane, i-LED ikhanya kakhulu, kodwa iba yincane i-engeli yokubuka yesibonisi.Ngokuvamile, i-LED engu-100-degree kufanele ikhethwe ukuze kuqinisekiswe i-engeli yokubuka eyanele yesikrini sokubonisa.Ezibonisini ezinamachashazi ahlukene namabanga okubuka ahlukene, ibhalansi kufanele itholakale ekukhanyeni, engeli, namanani.

5. Ukuvumelana?

Isibonisi se-LED esinombala ogcwele sakhiwe inqwaba yama-LED abomvu, aluhlaza naluhlaza.Ukukhanya nokuvumelana kwe-wavelength kombala ngamunye we-LED kunquma ukuvumelana kokukhanya, ukungaguquguquki kwebhalansi emhlophe kanye ne-chromaticity yaso sonke isibonisi.ukungaguquguquki.Ngokuvamile, abakhiqizi besibonisi se-LED esinemibala egcwele badinga abahlinzeki bedivayisi ukuthi banikeze ama-LED ngebanga le-wavelength elingu-5nm kanye nebanga lokukhanya elingu-1:1.3.Lezi zinkomba zingazuzwa umphakeli wedivayisi ngomshini we-spectroscopy.Ukuvumelana kwe-voltage ngokuvamile akudingekile.Njengoba i-LED ine-engeli, isibonisi se-LED esinemibala egcwele sibuye sibe ne-angular directionality, okungukuthi, uma ibukwa ngama-engeli ahlukene, ukukhanya kwayo kuzokwanda noma kwehle.

Ngale ndlela, ukungaguquguquki kwe-engeli yama-LED abomvu, aluhlaza, naluhlaza kuzothinta kakhulu ukuvumelana kwebhalansi emhlophe kuma-engeli ahlukene, futhi kuthinte ngokuqondile ukuthembeka kombala wevidiyo wesikrini sokubonisa.Ukuze ufinyelele ukuvumelana okuhambisanayo kwezinguquko zokukhanya kwama-LED abomvu, aluhlaza, naluhlaza okwesibhakabhaka ngama-engeli ahlukene, kuyadingeka ukwenza ukwakheka kwesayensi ngokuqinile ekwakhiweni kwelensi yephakeji kanye nokukhetha kwempahla eluhlaza, okuncike ezingeni lobuchwepheshe lephakheji. umphakeli.Ukuze uthole isibonisi se-LED esinemibala egcwele enebhalansi emhlophe eqondisayo engcono kakhulu, uma ukuvumelana kwe-engeli ye-LED kungekuhle, umphumela webhalansi omhlophe wesikrini sonke kuma-engeli ahlukene uzoba mubi.Izici zokungaguquguquki kwe-engeli zamadivayisi e-LED zingalinganiswa ngesihloli esihlanganisa i-engeli ye-LED, ebaluleke kakhulu kuzibonisi ezimaphakathi neziphezulu.
