Emva kweminyaka yophuhliso, i-anode yesiqhelo ye-anode ye-LED yenze ikhonkco lemizi-mveliso elizinzileyo, eliqhuba ukuthandwa kweziboniso ze-LED.Nangona kunjalo, ikwanazo nezingeloncedo zobushushu bescreen esiphakamileyo kunye nokusetyenziswa kwamandla ngokugqithisileyo.Emva kokuvela kwe-cathode eqhelekileyo ye-LED yokubonisa iteknoloji yonikezelo lwamandla, iye yatsala ingqalelo enkulu kwimarike yokubonisa i-LED.Le ndlela yokubonelela ngombane inokufezekisa ukonga amandla aphezulu angama-75%.Ke yintoni itekhnoloji ye-cathode ye-LED eqhelekileyo yokubonisa amandla?Ziziphi iingenelo zobu bugcisa?
1. Yintoni i-LED cathode eqhelekileyo?
"I-cathode eqhelekileyo" ibhekisela kwindlela eqhelekileyo yokunikezelwa kwamandla e-cathode, eneneni iteknoloji yokugcina amandla kwizikrini zokubonisa i-LED.Kuthetha ukusebenzisa indlela eqhelekileyo ye-cathode ukunika amandla isikrini sokubonisa i-LED, oko kukuthi, i-R, G, B (ebomvu, eluhlaza, eluhlaza okwesibhakabhaka) yamaso esibane se-LED anikwe amandla ngokwahlukeneyo, kwaye okwangoku kunye ne-voltage yabelwe ngokuchanekileyo kwi-R. , G, B izibane zesibane ngokulandelanayo, kuba i-voltage esebenza ngokufanelekileyo kunye nekhoyo ngoku efunwa yi-R, G, B (ebomvu, eluhlaza, eluhlaza okwesibhakabhaka) iintsimbi zesibane ziyahluka.Ngaloo ndlela, i-current yokuqala idlula kwiintsimbi zesibane kwaye emva koko i-electrode engafanelekanga ye-IC, ukuhla kwamandla ombane kuya kuncitshiswa, kwaye ukuchasana kwangaphakathi kwe-conduction kuya kuba kuncinci.
2. Uthini umahluko phakathi kwe-cathode eqhelekileyo kunye nee-anode eziqhelekileyo ze-LED?
①.Iindlela ezahlukeneyo zobonelelo lwamandla:
Indlela eqhelekileyo yonikezelo lwamandla e-cathode kukuba i-current yokuqala idlula kwi-bead yesibane kwaye emva koko iye kwipali engafanelekanga ye-IC, enciphisa ukuhla kwamandla ombane ngaphambili kunye nokuxhatshazwa kwangaphakathi.
I-anode eqhelekileyo kukuba i-current iphuma kwibhodi ye-PCB ukuya kwi-bead yesibane, kwaye inika amandla ku-R, G, B (obomvu, oluhlaza, ohlaza okwesibhakabhaka) ngokufanayo, okukhokelela ekuhlahleni okukhulu kombane kwisekethe.
②.Amandla ombane ahlukeneyo:
I-cathode eqhelekileyo, iya kubonelela ngoku kunye ne-voltage kwi-R, G, B (ebomvu, eluhlaza, eluhlaza okwesibhakabhaka) ngokwahlukileyo.Iimfuno zombane ezibomvu, eziluhlaza kunye nezibane eziluhlaza zihlukile.Iimfuno zombane zamaso ezibane ezibomvu zimalunga ne-2.8V, kwaye imfuno yombane yamaso esibane esiluhlaza-luhlaza malunga ne-3.8V.Unikezelo lwamandla olunjalo lunokufezekisa unikezelo lwamandla oluchanekileyo kunye nokusetyenziswa kwamandla amancinci, kwaye ukushisa okwenziwa yi-LED ngexesha lomsebenzi kuphantsi kakhulu.
I-anode eqhelekileyo, kwelinye icala, inika i-R, G, B (ebomvu, eluhlaza, eluhlaza okwesibhakabhaka) i-voltage ephezulu kune-3.8V (efana ne-5V) yokunikezelwa kombane odibeneyo.Ngeli xesha, i-voltage efunyenwe ngobomvu, eluhlaza kunye nohlaza okwesibhakabhaka yi-5V edibeneyo, kodwa i-voltage ye-voltage efanelekileyo efunekayo ngamaso ezibane ezithathu iphantsi kakhulu kune-5V.Ngokutsho kwefomula yamandla P = UI, xa i-current ihleli ingatshintshi, i-voltage ephezulu, amandla aphezulu, oko kukuthi, ukusetyenziswa kwamandla amakhulu.Ngelo xesha, i-LED iya kuvelisa ubushushu obuninzi ngexesha lomsebenzi.
II-Global Third-Generation yeSikhusi se-LED sangaphandle seNtengiso siphuhliswe yi-XYGLED, yamkela icathode eqhelekileyo.Xa kuthelekiswa ne-5V yendabuko ebomvu, eluhlaza, kunye ne-blue-emitting diodes, i-pali efanelekileyo ye-chip ye-LED ebomvu yi-3.2V, ngelixa ii-LED eziluhlaza kunye ne-blue ziyi-4.2V, ukunciphisa ukusetyenziswa kwamandla ubuncinane ngama-30% kwaye kubonisa amandla abalaseleyo- ukonga kunye nokusebenza kokunciphisa ukusetyenziswa.
3. Kutheni umboniso we-LED oqhelekileyo we-cathode uvelisa ubushushu obuncinci?
Imowudi ekhethekileyo yonikezelo lwamandla e-cathode yesikrini esibandayo yenza umboniso we-LED uvelise ubushushu obuncinci kunye nokunyuka kobushushu obuphantsi ngexesha lokusebenza.Phantsi kweemeko eziqhelekileyo, kwisimo esimhlophe sokulinganisela kwaye xa udlala iividiyo, iqondo lokushisa kwesikrini esibandayo limalunga ne-20 ℃ ngaphantsi kunelo lomboniso we-LED oqhelekileyo wangaphandle wemodeli efanayo.Kwiimveliso zeempawu ezifanayo kunye nokuqaqamba okufanayo, ubushushu besikrini somboniso we-cathode oqhelekileyo we-LED bungaphezulu kwama-20 degrees ngaphantsi kwe-anode eqhelekileyo yeemveliso zokubonisa i-LED, kunye nokusetyenziswa kwamandla kungaphezulu kwe-50% ngaphantsi koko. yeemveliso eziqhelekileyo zokubonisa i-anode ye-LED.
Ukushisa okugqithisileyo kunye nokusetyenziswa kwamandla okuboniswa kwe-LED kuye kwaba zizinto eziphambili ezichaphazela ubomi benkonzo yeemveliso zokubonisa i-LED, kwaye "i-cathode ye-LED ebonisa umboniso" inokusombulula ezi ngxaki zimbini kakuhle.
