Kupenya kwavo nekusiyana kwakafanana nematerevhizheni eOLED, asi mutengo wavo wakadzikira uye hapana njodzi yekutsva skrini.

Saka chii chaizvo chinonzi Mini LED?

Parizvino, iyo Mini LED yatiri kukurukura haisi tekinoroji nyowani yekuratidzira, asi mhinduro yakagadziridzwa senge backlight sosi yemvura yekristaro inoratidzira, iyo inogona kunzwisiswa sekusimudzira kweiyo backlight tekinoroji.

Mazhinji maLCD TVs anoshandisa LED (Chiedza Emitting Diode) sechiedza chekumashure, nepo Mini LED TVs inoshandisa Mini LED, diki mwenje sosi pane echinyakare maLED.Hupamhi hweMini LED hunosvika mazana maviri microns (0.008 inches), inova chikamu chimwe muzvishanu cheyakajairwa saizi ye LED inoshandiswa muLCD mapaneru.

Nekuda kwehukuru hwavo hudiki, vanogona kuparadzirwa zvakanyanya pahwindo rese.Kana paine yakakwana LED backlight muchiratidziro, iyo kupenya kutonga, ruvara gradient, uye zvimwe zvinhu zvechidzitiro zvinogona kudzorwa zvakanaka zvakakwana, zvichipa zvirinani mufananidzo.

Uye yechokwadi Mini LED TV inoshandisa Mini LED zvakananga sepixels panzvimbo yebacklight.Samsung yakaburitsa 110 inch Mini LED TV paCES 2021, iyo ichavhurwa munaKurume, asi zvakaoma kuona zvigadzirwa zvepamusoro-soro zvichionekwa mudzimba zhinji.

Ndeapi mabhureki anoronga kuburitsa Mini LED zvigadzirwa?

Takatoona kuCES yegore rino kuti TCL yakaburitsa “ODZero” Mini LED TV.Asi izvo, TCL yaive zvakare yekutanga kugadzira kuburitsa Mini LED TVs.LG's QNED TVs yakatangwa paCES uye Samsung's Neo QLED TVs zvakare inoshandisa Mini LED backlight tekinoroji.

Chii chakashata neMini LED backlight?

1, Kumashure kweMini LED backlight kuvandudza

Sezvo China ichipinda munhanho yeyakajairwa yekudzivirira uye kutonga kwedenda, maitiro ekudzoreredza ekushandisa ari kubatanidzwa zvishoma nezvishoma.Tichitarisa kumashure muna 2020, "hupfumi hwepamba" hapana mubvunzo kuti ndiyo yakanyanya kupisa musoro mundima yevatengi, uye "hupfumi hwepamba" hwabudirira, uku ichitsigirawo kukura kwakazara kwehunyanzvi hwekuratidzira hwakadai se8K, quantum dots, uye Mini LED. .Naizvozvo, nekusimudzirwa kwakasimba kwemabhizinesi anotungamira akadai seSamsung, LG, Apple, TCL, uye BOE, yekupedzisira tsananguro yeMini TV inoshandisa yakananga pasi Mini LED backlighting yava hotspot yeindasitiri.Muna 2023, zvinotarisirwa kuti kukosha kwemusika weTV backboards uchishandisa Mini LED backlight ichasvika 8.2 bhiriyoni emadhora ekuAmerica, ne20% yemutengo uri muMini LED machipisi.

Iyo yakatwasuka pasi backlight Mini LED ine mabhenefiti epamusoro resolution, hupenyu hurefu, yakanyanya kupenya inopenya, uye yakakwirira kuvimbika.Panguva imwecheteyo, iyo Mini LED, yakasanganiswa neyemuno dimming zoning control, inogona kuwana yakakwira musiyano HDR;Yakasanganiswa neakakwira color gamut quantum dots, yakafara color gamut> 110% NTSC inogona kuwanikwa.Naizvozvo, Mini LED tekinoroji yakakwezva kutarisisa uye kuve isingadzivisike maitiro mune tekinoroji nekusimudzira musika.

2, Mini LED backlight chip paramita

Guoxing Semiconductor, mubatsiri weGuoxing Optoelectronics, akashanda nesimba kuvandudza Mini LED epitaxy uye chip tekinoroji mumunda weMini LED backlight application.Yakakosha tekinoroji mabhindauko akaitwa mukuvimbika kwechigadzirwa, anti-static kugona, kugadzikana kwewelding, uye kujeka kwemavara kuenderana, uye maviri akatevedzana eMini LED backlight chip zvigadzirwa, zvinosanganisira 1021 uye 0620, akaumbwa.Panguva imwecheteyo, kuitira kuti zvigadzirise zviri nani kune zvinodiwa zveMini COG packaging, Guoxing Semiconductor yakagadzira itsva high-voltage 0620 chigadzirwa, ichipa vatengi zvimwe zvingasarudzwa.

3, Hunhu hweMini LED backlight chip

1. High consistency epitaxial structure design, ine simba rinopesana ne-static simba re chip

Kuwedzera wavelength kusungirirwa kweMini LED backlight machipisi, Guoxing Semiconductor inotora yakasarudzika epitaxial layer stress control tekinoroji kudzikisa kushushikana kwemukati uye kuve nechokwadi chekuenderana muhuwandu hwekukura kwemaitiro.Panyaya yemachipisi, yakagadziridzwa uye yakavimbika zvakanyanya DBR flip chip mhinduro inoshandiswa kuwana ekupedzisira-yepamusoro anti-static kugona.Zvinoenderana nemhedzisiro yekuedzwa kweyechitatu-bato rabhoritari, iyo anti-static kugona kweGuoxing Semiconductor Mini LED backlight chip inogona kudarika 8000V, uye iyo anti-static performance yechigadzirwa inosvika kumberi kweindasitiri.
