Kuwala kwawo ndi kusiyana kwake kumafanana ndi ma TV a OLED, koma mtengo wawo ndi wotsika kwambiri ndipo palibe chiopsezo choyaka chophimba.

Ndiye kodi Mini LED ndi chiyani kwenikweni?

Pakalipano, Mini LED yomwe tikukambirana si teknoloji yatsopano yowonetsera, koma njira yabwino yothetsera magalasi amadzimadzi amadzimadzi, omwe amatha kumveka ngati kukweza kwa teknoloji ya backlight.

Ma TV ambiri a LCD amagwiritsa ntchito LED (Light Emitting Diode) ngati chowunikira kumbuyo, pomwe ma Mini LED TV amagwiritsa ntchito Mini LED, gwero laling'ono lowala kuposa ma LED achikhalidwe.M'lifupi mwa Mini LED ndi pafupifupi 200 microns (0.008 mainchesi), yomwe ndi gawo limodzi mwa magawo asanu a kukula kwa LED komwe kumagwiritsidwa ntchito mu mapanelo a LCD.

Chifukwa cha kukula kwawo kochepa, amatha kugawidwa kwambiri pazenera lonse.Pakakhala kuwala kokwanira kwa LED pazenera, kuwongolera kowala, kupendekera kwamtundu, ndi mbali zina za chophimba zimatha kuyendetsedwa bwino, motero kumapereka chithunzithunzi chabwinoko.

Ndipo Mini LED TV yeniyeni imagwiritsa ntchito Mini LED molunjika ngati ma pixel m'malo mowunikira kumbuyo.Samsung idatulutsa 110 inch Mini LED TV pa CES 2021, yomwe idzayambike mu Marichi, koma ndizovuta kuwona zinthu zapamwamba ngati izi zikuwonekera m'mabanja ambiri.

Ndi mitundu iti yomwe ikukonzekera kuyambitsa zinthu za Mini LED?

Tawona kale ku CES ya chaka chino kuti TCL yatulutsa "ODZero" Mini LED TV.M'malo mwake, TCL inalinso wopanga woyamba kukhazikitsa Mini LED TV.Ma TV a LG a QNED omwe adakhazikitsidwa pa CES ndi ma Neo QLED TV a Samsung amagwiritsanso ntchito ukadaulo wa Mini LED backlight.

Kodi cholakwika ndi Mini LED backlight ndi chiyani?

1, Mbiri yakukula kwa Mini LED backlight

Pamene China ikulowa mu gawo lokhazikika la kupewa ndi kuwongolera miliri, kuyambiranso kwakumwa kukuphatikizana pang'onopang'ono.Tikayang'ana m'mbuyo ku 2020, "chuma chapakhomo" mosakayikira ndiye mutu wovuta kwambiri pazamalonda, ndipo "chuma chapakhomo" chakula, komanso kuthandizira kukula kwaukadaulo watsopano wowonetsera monga 8K, madontho a quantum, ndi Mini LED. .Chifukwa chake, ndi kukwezedwa kwamphamvu kwamabizinesi otsogola monga Samsung, LG, Apple, TCL, ndi BOE, ma Mini TV a mini omwe amagwiritsa ntchito kuyatsa kwa Mini LED asanduka malo ogulitsa kwambiri.Mu 2023, zikuyembekezeredwa kuti mtengo wamsika wa ma TV backboards ogwiritsa ntchito Mini LED backlight ifika 8.2 biliyoni US dollars, ndi 20% ya mtengo wake kukhala mu Mini LED tchipisi.

Mini LED yowongoka yowongoka kumbuyo ili ndi zabwino zake pakusankha kwakukulu, moyo wautali, kuwala kowala kwambiri, komanso kudalirika kwambiri.Panthawi imodzimodziyo, Mini LED, kuphatikizapo kulamulira kwa dimming m'deralo, ikhoza kukwaniritsa HDR yosiyana kwambiri;Kuphatikizidwa ndi madontho apamwamba amtundu wa gamut quantum, mtundu waukulu wa gamut> 110% NTSC ukhoza kutheka.Chifukwa chake, ukadaulo wa Mini LED wakopa chidwi kwambiri ndikukhala njira yosapeŵeka yaukadaulo ndi chitukuko cha msika.

2, Mini LED backlight chip magawo

Guoxing Semiconductor, kampani yothandizirana ndi Guoxing Optoelectronics, yapanga mwachangu Mini LED epitaxy ndi ukadaulo wa chip m'munda wa Mini LED backlight application.Kupambana kwakukulu kwaukadaulo kwapangidwa pakudalirika kwazinthu, kudalirika kwa anti-static, kukhazikika kwa kuwotcherera, komanso kusasinthika kwamtundu, ndipo magawo awiri a Mini LED backlight chip chip, kuphatikiza 1021 ndi 0620, apangidwa.Panthawi imodzimodziyo, kuti agwirizane bwino ndi zofunikira za phukusi la Mini COG, Guoxing Semiconductor yapanga mankhwala atsopano a 0620 apamwamba, opatsa makasitomala zosankha zambiri.

3, Makhalidwe a Mini LED backlight chip

1. Mapangidwe apamwamba a epitaxial, okhala ndi mphamvu yotsutsa-static ya chip

Kupititsa patsogolo kuchuluka kwa mafunde a Mini LED backlight tchipisi, Guoxing Semiconductor imatengera ukadaulo wapadera wa epitaxial wosanjikiza wowongolera kupsinjika kuti muchepetse kupsinjika kwamkati ndikuwonetsetsa kusasinthika pakukula kwa chitsime cha quantum.Pankhani ya tchipisi, njira yokhazikika komanso yodalirika ya DBR flip chip imagwiritsidwa ntchito kuti ikwaniritse luso lapamwamba kwambiri la anti-static.Malingana ndi zotsatira za mayesero a labotale ya chipani chachitatu, mphamvu yotsutsa-static ya Guoxing Semiconductor Mini LED backlight chip imatha kupitirira 8000V, ndipo ntchito yotsutsa-static ya mankhwalawa imafika kutsogolo kwa makampani.
