1. Iengile yokujonga
I-angle yokujonga isiboniso se-LED ixhomekeke kwi-angle yokujonga izibane ze-LED. Okwangoku, uninziumboniso we-LED wangaphandlekwayeizikrini zokubonisa ze-LED zangaphakathi sebenzisa ii-LED ze-SMD ezine-angle yokujonga ethe tye kunye nethe nkqo ye-140 °. Iziboniso ze-LED zesakhiwo esiphakamileyo zifuna ii-engile eziphezulu zokujonga ngokuthe nkqo. I-angle yokujonga kunye nokukhanya kuyaphikisana, kwaye i-angle enkulu yokujonga ngokuqinisekileyo iya kunciphisa ukukhanya. Ukukhethwa kwe-angle yokujonga kufuneka kugqitywe ngokubhekiselele kusetyenziso oluthile.
2. Ukuqaqamba
Ukukhanya kwesibane sesibane se-LED sisigqibo esibalulekileyo sokuqaqamba komboniso we-LED. Ukuphakama kokukhanya kwe-LED, mkhulu umda wokusetyenziswa kwangoku, okulungileyo ekugcineni ukusetyenziswa kwamandla kunye nokugcina i-LED izinzile. Ii-LED zinamaxabiso ahlukeneyo eengile. Xa ukukhanya kwe-chip kulungiswa, i-angle encinci, i-LED ekhanyayo, kodwa i-angle encinci yokujonga isiboniso. Ngokuqhelekileyo, i-LED ye-120-degree kufuneka ikhethwe ukuqinisekisa i-angle yokujonga eyaneleyo yesiboniso. Kwimiboniso enamachaphaza ahlukeneyo kunye nemigama ehlukeneyo yokujonga, indawo yokulinganisa kufuneka ifunyenwe ekukhanyeni, i-angle kunye nexabiso.
3. Izinga lokungaphumeleli
Ukusukela okoUmboniso ogcweleyo we-LED wombala yenziwe ngamashumi amawaka okanye namakhulu amawaka eepikseli ezenziwe ngee-LEDs ezibomvu, eziluhlaza kunye neziluhlaza okwesibhakabhaka, ukusilela kwawo nawuphi na umbala we-LED kuya kuchaphazela isiphumo sokubonwayo siso sonke isiboniso se-LED. Ngokuqhelekileyo, izinga lokungaphumeleli kwesiboniso se-LED akufanele libe phezulu kune-3/10,000 ngaphambi kokuba isiboniso se-LED siqale ukuhlanganiswa kwaye siguge iiyure ezingama-72 ngaphambi kokuthunyelwa.
4. Ikhono le-Antistatic
I-LED sisixhobo se-semiconductor, esinovelwano kumbane ongatshintshiyo kwaye sinokukhokelela ngokulula kumbane ongatshintshiyo. Ke ngoko, isakhono esichasene ne-static sibaluleke kakhulu kubomi besikrini sokubonisa. Ngokubanzi, ukusilela kombane wovavanyo lwemowudi ye-electrostatic ye-LED yomzimba womntu akufanele kube ngaphantsi kwe-2000V.
5. Ukungqinelana
Umbala ogcweleyo wesikrini sokubonisa i-LED yenziwe ngeepixels ezenziwe ngee-LED ezininzi ezibomvu, eziluhlaza, neziluhlaza. Ukungaguquguquki kokuqaqamba kunye nobude obungangelanga bombala ngamnye we-LED bumisela ukuqaqamba ukungaguquguquki, ukuhambelana kwebhalansi emhlophe, kunye nokuhambelana kwechromaticity yesikrini sonke sokubonisa.
Umbala ogcweleyo we-LED ubonisa i-angular directionality, oko kukuthi, ukukhanya kwayo kuya kwanda okanye kunciphe xa kujongwa kwii-angles ezahlukeneyo. Ngale ndlela, ukuhambelana kwe-angular ye-LED ebomvu, eluhlaza, kunye neluhlaza okwesibhakabhaka kuya kuchaphazela kakhulu ukuhambelana kwebhalansi emhlophe kwii-angles ezahlukeneyo, kwaye kuchaphazele ngokuthe ngqo ukuthembeka kombala wevidiyo kwisibonisi. Ukufezekisa ukuhambelana okuhambelana nokukhanya kokukhanya kwee-LED ezibomvu, eziluhlaza kunye nohlaza okwesibhakabhaka kwii-engile ezahlukeneyo, kuyimfuneko ukwenza ngokungqongqo uyilo lwesayensi kuyilo lwelensi yokupakisha kunye nokukhethwa kwezinto eziluhlaza, ezixhomekeke kwinqanaba lobugcisa. umthengisi wokupakisha. Kungakhathaliseki ukuba ibhalansi emhlophe ilungile kangakanani, ukuba i-angle ye-LED ayilungile, umphumo omhlophe we-engile ye-engile ezahlukeneyo zesikrini uya kuba mbi.
6. Iimpawu zokuthomalalisa
Emva kokuba isiboniso se-LED sisebenza ixesha elide, ukukhanya kuya kuhla kwaye umbala wesiboniso uya kuba ungahambelani, nto leyo ebangelwa ubukhulu becala ukuthotywa kokukhanya kwesixhobo se-LED. Ukuthotywa kokukhanya kwe-LED kuya kunciphisa ukuqaqamba kwesikrini sonke se-LED. Ukungahambelani kokukhanya kokukhanya kwe-LED ebomvu, eluhlaza kunye nohlaza okwesibhakabhaka kuya kubangela ukungahambelani kombala wesiboniso se-LED. Izibane ze-LED ezikumgangatho ophezulu zinokulawula kakuhle ubukhulu bokukhanya kokukhanya. Ngokomgangatho wokukhanya kwe-20mA kwiqondo lokushisa kwegumbi kwiiyure ze-1000, ukutshatyalaliswa okubomvu kufuneka kube ngaphantsi kwe-2%, kunye nokunciphisa okuluhlaza okwesibhakabhaka kunye nohlaza kufuneka kube ngaphantsi kwe-10%. Ngoko ke, zama ukungasebenzisi i-20mA yangoku kwi-LED eluhlaza okwesibhakabhaka kunye nohlaza kuyilo lokubonisa, kwaye kungcono ukusebenzisa kuphela i-70% ukuya kwi-80% ye-rated yangoku.
Ukongeza kwiimpawu zokuthomalalisa ezinxulumene neempawu ze-LED ezibomvu, eziluhlaza kunye neziluhlaza okwesibhakabhaka ngokwazo, ezisetyenziswayo ngoku, uyilo lokuphelisa ubushushu bebhodi yePCB, kunye nobushushu be-ambient yesikrini sokubonisa zonke zichaphazela ukuthomalalisa.
7. Ubungakanani
Ubungakanani besixhobo se-LED buchaphazela umgama we-pixel wesiboniso se-LED, oko kukuthi, isisombululo. Uhlobo lwe-SMD3535 LEDs zisetyenziswa kakhuluP6, P8, P10 umboniso we-LED wangaphandle, SMD2121 LED isetyenziswa ikakhuluP2.5,P2.6,P2.97,P3.91 isikrini sangaphakathi . Kwisiseko sokuba i-pixel pitch ihlala ingatshintshi, ubukhulu bezibane ze-LED buyanda, obunokunyusa indawo yokubonisa kunye nokunciphisa i-graininess. Nangona kunjalo, ngenxa yokunciphisa indawo emnyama, umahluko uya kuncitshiswa. Ngokuchasene noko, ubukhulu be-LED buyancipha,okunciphisa indawo yokubonisa kunye nokwandisa i-graininess, indawo emnyama iyanda, inyusa izinga lokungafani.
8. Ixesha lokuphila
Ubomi bethiyori yesibane se-LED ziiyure ezingama-100,000, ubude obude kakhulu kunamanye amacandelo obomi bomboniso we-LED. Ngoko ke, ngokude nje umgangatho wezibane ze-LED ziqinisekisiwe, ukusebenza kwangoku kufanelekileyo, i-PCB yokuyila ukutshatyalaliswa kobushushu ifanelekile, kwaye inkqubo yokuvelisa ibonakaliso ingqongqo, izibane ze-LED ziya kuba ziindawo ezihlala zihlala kwi-LED yodonga lwevidiyo.
Iimodyuli ze-LED zijonga i-70% yexabiso le-LED, ngoko ke iimodyuli ze-LED zinokumisela umgangatho weziboniso ze-LED. Iimfuno zetekhnoloji ephezulu yesikrini sokubonisa i-LED yindlela yophuhliso lwexesha elizayo. Ukususela kulawulo lweemodyuli ze-LED, ukukhuthaza inguqu ye-China ukusuka kwilizwe elikhulu lokuvelisa umboniso we-LED ukuya kwilizwe lokuvelisa i-LED enamandla.
