Yintoni enokwenziwa nguMboniso woMbane we-LED kwiShishini lakho leNtengiso yeDijithali?

Ugcino lwe-LED olukhokelela kwiscreen, esikwabizwa ngokuba yiCommon Anode Led screen.

I-chipset ye-LED inee-terminals ezimbini, i-anode kunye ne-cathode, kwaye umbala ngamnye ogcweleyo we-LED uqukethe ezintathu ze-chipset ze-LED. (obomvu, oluhlaza kunye noluhlaza okwesibhakabhaka).

Kuyilo lwesiqhelo lwe-Anode, i-terminals yazo zonke i-3 (ebomvu, eluhlaza & eluhlaza okwesibhakabhaka) ii-LED zidibene kunye kunye ne-resistor yangaphandle ye-ballast yongezwa ngokulandelelana kunye ne-LED ebomvu yokugcina i-voltage eqhubekayo kunye nokulinganisa ukuhla kwamandla kuzo zonke ii-LED ezintathu.

Oku emva koko kunciphisa indawo ekhoyo yee-LEDs zenza ukuba i-pixel entle ibe nzima ukuyifezekisa, ngelixa ikwangumthombo wobushushu owongezelelweyo kwaye ikhawulezisa inkqubo yokuguga kwaye inciphisa ubomi.

Umboniso we-LED ogcina umbane wamkela uyilo lwenkqubo yokubonisa ye-LED enamandla aphantsi enombala ogcweleyo.

Sisicelo sokudibanisa inkqubo yobunjineli edibanisa ubuchwephesha bobunjineli bale mihla obufana nobuchwephesha bekhompyuter, itekhnoloji ye-elektroniki, itekhnoloji yokukhanya, itekhnoloji yombane kunye netekhnoloji yolwakhiwo.

Kwitekhnoloji yeCathode eqhelekileyo, umbane ohlukeneyo, ozinikeleyo wonikezelo lwamandla unikezelwa kwii-LED ezibomvu, eziluhlaza kunye neziluhlaza okwesibhakabhaka ezenza amandla anikezelwe kwi-LED ebomvu alawulwe ngokwahlukileyo kwaye aphelise imfuneko ye-ballast resistor.

Inkulu, ixesha elide lokudlala, kunye nokusetyenziswa kwayo kwamandla kuphawu oluphambili lwe-LED yokubonisa inkxalabo yabathengiUmboniso osebenza ngamandla ngokwenene awuthembeli kuphela kwi-hardware ethile okanye ukuphuculwa kweteknoloji yesofthiwe yesiboniso, kodwa kunye nesiphumo sokwenziwa kwezinto ezintsha zobuchwepheshe kwisisombululo esipheleleyo.

Izikrini zentengiso ze-LED ezigcina amandla, i-P4MM yangaphandle, i-P5.926MM, i-P6.67MM, i-P8MM, i-P10MM, emva kweminyaka yophando kunye nophuhliso kunye nokuthelekisa okuvuthiweyo kokuvavanywa, ukonga amandla angaphezu kwe-40% xa kuthelekiswa nezikrini ze-LED zendabuko.

Ukunciphisa umboniso wokusetyenziswa kwamandla kwesikrini lukhokelo olubalulekileyo lophuhliso lwetekhnoloji yesikrini se-LED.

Izikrini zokonga amandla e-LED zamkela iikhonsepthi zoyilo zamva nje, zithathela ingqalelo izinto ezinje ngeendleko, kwaye ziyile ukusetyenziswa kwamandla aphantsi kwezikrini zokubonisa i-LED ukusuka kule miba ilandelayo:

A: Izibane ezibomvu, eziluhlaza neziluhlazazinikwe amandla yi-3.8V kunye nokusebenza kakuhle konikezelo lwamandla kungaphezulu kwama-85%.

B:Ukusebenzisa i-IC eyonga amandla aphezulu, i-channel ephantsi kakhulu yokuguqula i-voltage, i-VDS = 0.2V, inciphisa kakhulu ixabiso lombane wesekethe yokuqhuba i-LED.

C: Ukusetyenziswa kweentsimbi ezinkulu zesibane se-chip 1 amaxesha agqamile kuneentsimbi eziqhelekileyo zesibane se-LED, ukwenzela ukuba phantsi kweemfuno zokukhanya okufanayo, i-LED idinga ukuqhuba okuncinci ngoku, oko kukuthi, ukusetyenziswa kwamandla kuyancipha.

D: Inkqubo yokulawula ekrelekreleiphuhliswe ngokuzimeleyo inokulungelelanisa ngokuzenzekelayo ukukhanya kwesikrini esikhulu se-LED ngokokukhanya kwendawo yangaphandle, ukuze ungachithi amandla okanye ubangele ungcoliseko lokukhanya.

E:Iziboniso ze-LED ezigcina amandla, Ngokusekelwe kwiZikrini ze-LED eziqhelekileyo, ziphucule ngokuchanekileyo umphumo wokubonisa kunye nokusebenza kokusetyenziswa kwamandla, ukwenzela ukuba umboniso we-LED wokusetyenziswa kwempembelelo kunye nokusetyenziswa kwamandla okubanzi kuye kwafikelela kumanqanaba ahamba phambili kwishishini.

Abanini beentengiso bakhetha iziboniso ze-LED kunye nokusebenza kakuhle kwamandla.

Ngetekhnoloji ye-cathode eqhelekileyo yokubonisa i-LED, iqondo lobushushu lesikrini elikhokeleyo lehlise i-12.4 degree.

Kule meko inokunceda kakhulu ukufana kombala kunye nexesha elide lokubonisa i-LED.

Abona baxhamli bathe ngqo kwimiboniso yokonga amandla e-LED kufuneka ibe ngabanini bentengiso yentengiso yangaphandle, hayi nje ixesha elide lokusebenzisa, kodwa nokonga amandla xa udonga lwevidiyo lukhanya ixesha elide.

Qhagamshelana ne-YONWAYTECH ngenkqubo yogcino lwamandla ekhokelela kwisisombululo.
