Ukukhanya kwabo kunye nokwahlukileyo kuthelekiswa nomabonwakude we-OLED, kodwa ixabiso labo liphantsi kakhulu kwaye akukho mngcipheko wokutsha kwesikrini.

Ke yintoni kanye iMini LED?

Okwangoku, i-Mini ye-LED esiyixubushayo ayiyona iteknoloji entsha yokubonisa ngokupheleleyo, kodwa isisombululo esiphuculweyo njengomthombo we-backlight we-crystal displays ye-liquid displays, enokuqondwa njengokuphuculwa kobuchwephesha be-backlight.

Uninzi lwee-TV ze-LCD zisebenzisa i-LED (i-Light Emitting Diode) njenge-backlight, ngelixa ii-TV ze-Mini LED zisebenzisa i-Mini LED, umthombo omncinci wokukhanya kune-LED zendabuko.Ububanzi be-Mini LED bumalunga ne-200 microns (0.008 intshi), enye yesihlanu yesayizi ye-LED eqhelekileyo esetyenziswa kwiipaneli ze-LCD.

Ngenxa yobungakanani babo buncinci, banokusasazwa ngakumbi kwiscreen sonke.Xa kukho ukukhanya okwaneleyo kwe-LED kwisikrini, ulawulo lokukhanya, i-gradient yombala, kunye neminye imiba yesikrini inokulawulwa kakuhle ngokwaneleyo, ngaloo ndlela inika umgangatho womfanekiso ongcono.

Kwaye i-Mini ye-TV ye-LED yokwenyani isebenzisa i-Mini ye-LED ngokuthe ngqo njengeepikseli endaweni yesibane esingasemva.I-Samsung ikhuphe i-intshi ye-110 ye-Mini ye-TV ye-LED kwi-CES 2021, eya kuqaliswa ngo-Matshi, kodwa kunzima ukubona iimveliso ezinjalo eziphezulu zivela kumakhaya amaninzi.

Zeziphi iibrendi eziceba ukusungula iimveliso ze-Mini ze-LED?

Sele sibonile kwi-CES yalo nyaka ukuba i-TCL ikhuphe i-“ODZero” Mini ye-TV ye-LED.Ngapha koko, i-TCL yayikwangumvelisi wokuqala ukuphehlelela iiTV ezincinci ze-LED.Ii-TV ze-QNED ze-LG ziphehlelelwe kwi-CES kunye nee-TV ze-Neo QLED ze-Samsung nazo zisebenzisa i-Mini ye-LED backlight technology.

Yintoni engalunganga ngesibane se-Mini LED?

1, Imvelaphi yophuhliso lwe-mini LED backlight

Njengoko i-China ingena kwinqanaba lesiqhelo lothintelo kunye nolawulo lwendyikityha, indlela yokubuyisela ukusetyenziswa ngokuthe ngcembe idibanisa.Ukujonga emva ngo-2020, "uqoqosho lwasekhaya" ngokungathandabuzekiyo sesona sihloko sishushu kakhulu kwintsimi yabathengi, kwaye "uqoqosho lwasekhaya" luphumelele, ngelixa likwaxhasa ukukhula okubanzi kobuchwephesha obutsha bokuboniswa njenge-8K, amachaphaza e-quantum, kunye ne-Mini LED. .Ke ngoko, ngonyuso oluluqilima lwamashishini aphambili anje nge-Samsung, LG, Apple, TCL, kunye ne-BOE, ii-TV ezincinci ze-Ultra ezisebenzisa ngokuthe ngqo i-Mini LED backlighting ziye zaba yindawo enkulu yoshishino.Ngo-2023, kulindeleke ukuba ixabiso lemarike ye-backboards ye-TV usebenzisa i-Mini LED backlight iya kufikelela kwi-8.2 yeebhiliyoni zeedola zase-US, kunye ne-20% yexabiso lexabiso likwi-Mini LED chips.

Isibane esisezantsi esithe ngqo se-Mini LED sinezibonelelo zesisombululo esiphezulu, ubomi obude, ukusebenza kakuhle kokukhanya, kunye nokuthembeka okuphezulu.Ngexesha elifanayo, i-Mini LED, idibaniswe nolawulo lwendawo yokunciphisa ubumnyama, inokufikelela kwi-HDR ephezulu;Idityaniswe nombala ophakamileyo wamachaphaza we-gamut quantum, umbala obanzi we-gamut>110% we-NTSC unokufumaneka.Ke ngoko, itekhnoloji ye-Mini ye-LED itsale umdla omkhulu kwaye ibe yinto engenakuthintelwa kubugcisa kunye nophuhliso lwentengiso.

2, iiparamitha zetshiphu ezikhanyayo ze-LED ezincinci

I-Guoxing Semiconductor, i-subsidiary ephethwe ngokupheleleyo ye-Guoxing Optoelectronics, iphuhlise ngokusebenzayo i-Mini LED epitaxy kunye ne-chip technology kwintsimi ye-Mini LED backlight applications.Ukuphumelela okuphambili kwezobugcisa kuye kwenziwa ekuthembekeni kwemveliso, ukukwazi ukulwa ne-static, ukuzinza kwe-welding, kunye nokuhambelana kombala okhanyayo, kunye nochungechunge ezimbini zeemveliso ze-Mini LED backlight chip, kuquka i-1021 kunye ne-0620, zenziwe.Ngelo xesha, ukwenzela ukuba ulungelelanise kakuhle iimfuno zokupakisha kwe-Mini COG, i-Guoxing Semiconductor iye yavelisa imveliso entsha ye-high-voltage 0620, inikezela abathengi ngeendlela ezininzi zokukhetha.

3, Iimpawu zeMini ye-LED backlight chip

1. Uyilo oluphezulu lwesakhiwo se-epitaxial, kunye nobuchule obunamandla obuchasayo be-chip

Ukomeleza i-wavelength concentration ye-Mini LED backlight chips, i-Guoxing Semiconductor ithatha itekhnoloji ekhethekileyo yokulawula uxinzelelo lwe-epitaxial ukunciphisa uxinzelelo lwangaphakathi kunye nokuqinisekisa ukungaguquguquki kwinkqubo yokukhula kakuhle kwe-quantum.Ngokubhekiselele kwiichips, isisombululo esilungiselelweyo nesithembekileyo se-DBR flip chip sisetyenziselwa ukufikelela kwi-ultra-high anti-static.Ngokweziphumo zovavanyo lwebhubhoratri yomntu wesithathu, i-anti-static ikhono le-Guoxing Semiconductor Mini LED backlight chip ingadlula i-8000V, kwaye ukusebenza kwe-anti-static kwemveliso kufikelela phambili kwishishini.
