Lawv qhov ci ntsa iab thiab qhov sib txawv yog piv rau OLED TVs, tab sis lawv cov nqi qis dua thiab tsis muaj kev pheej hmoo ntawm qhov screen hlawv.

Yog li dab tsi yog Mini LED?

Tam sim no, Mini LED peb tab tom tham txog tsis yog ib qho kev siv thev naus laus zis tshiab, tab sis kev txhim kho kev daws teeb meem raws li lub teeb pom kev zoo rau cov kua siv lead ua kua, uas tuaj yeem nkag siab tias yog kev hloov kho ntawm lub teeb pom kev zoo.

Feem ntau LCD TVs siv LED (Lub Teeb Emitting Diode) ua lub teeb nraub qaum, thaum Mini LED TVs siv Mini LED, lub teeb me me dua li cov LEDs.Qhov dav ntawm Mini LED yog kwv yees li 200 microns (0.008 nti), uas yog ib feem tsib ntawm tus qauv LED loj siv hauv LCD panels.

Vim lawv qhov me me, lawv tuaj yeem faib tau ntau dua thoob plaws lub vijtsam.Thaum muaj LED backlight txaus nyob rau hauv ib qho screen, lub brightness tswj, xim gradient, thiab lwm yam ntawm lub vijtsam tuaj yeem tswj tau zoo txaus, yog li muab cov duab zoo dua.

Thiab qhov tseeb Mini LED TV siv Mini LED ncaj qha li pixels es tsis txhob rov qab teeb.Samsung tau tshaj tawm 110 nti Mini LED TV ntawm CES 2021, uas yuav pib thaum Lub Peb Hlis, tab sis nws nyuaj rau pom cov khoom lag luam siab zoo li no tshwm sim hauv ntau tsev neeg.

Cov hom twg npaj yuav tshaj tawm cov khoom lag luam Mini LED?

Peb twb tau pom nyob rau xyoo no CES uas TCL tau tso tawm "ODZero" Mini LED TV.Qhov tseeb, TCL kuj yog thawj cov chaw tsim khoom tsim Mini LED TVs.LG's QNED TVs launched ntawm CES thiab Samsung's Neo QLED TVs kuj siv Mini LED backlight technology.

Dab tsi yog qhov tsis zoo ntawm Mini LED backlight?

1, Keeb kwm ntawm Mini LED backlight kev txhim kho

Raws li Tuam Tshoj nkag mus rau theem normalization ntawm kev tiv thaiv kab mob sib kis thiab kev tswj hwm, kev rov qab los ntawm kev noj yog maj mam sib sau ua ke.Saib rov qab rau xyoo 2020, "kev lag luam hauv tsev" yog qhov tsis txaus ntseeg lub ntsiab lus kub loj tshaj plaws hauv cov neeg siv khoom lag luam, thiab "kev lag luam hauv tsev" tau vam meej, thaum tseem txhawb nqa kev loj hlob ntawm cov cuab yeej tshiab xws li 8K, quantum dots, thiab Mini LED. .Yog li ntawd, nrog rau kev txhawb nqa muaj zog ntawm kev lag luam xws li Samsung, LG, Apple, TCL, thiab BOE, ultra siab txhais Mini TVs siv ncaj qha Mini LED backlighting tau dhau los ua kev lag luam hotspot.Hauv xyoo 2023, nws xav tias tus nqi lag luam ntawm TV backboards siv Mini LED backlight yuav ncav cuag 8.2 billion US las, nrog 20% ​​ntawm tus nqi faib ua hauv Mini LED chips.

Lub teeb ncaj nraim Mini LED muaj qhov zoo ntawm kev daws teeb meem siab, lub neej ntev, kev ua haujlwm siab luminous, thiab kev ntseeg siab.Nyob rau tib lub sijhawm, Mini LED, ua ke nrog lub zos dimming zoning tswj, tuaj yeem ua tiav qhov sib txawv HDR;Ua ke nrog cov xim siab gamut quantum dots, qhov dav xim gamut> 110% NTSC tuaj yeem ua tiav.Yog li ntawd, Mini LED thev naus laus zis tau nyiam ntau yam thiab dhau los ua ib qho kev tsis pom kev hauv kev siv tshuab thiab kev lag luam.

2, Mini LED backlight nti tsis

Guoxing Semiconductor, lub tuam txhab ua lag luam tag nrho ntawm Guoxing Optoelectronics, tau nquag tsim Mini LED epitaxy thiab nti thev naus laus zis hauv kev siv Mini LED backlight.Cov txheej txheem tseem ceeb tau ua tiav hauv cov khoom lag luam kev ntseeg siab, muaj peev xwm tiv thaiv zoo li qub, vuam ruaj khov, thiab lub teeb xim sib xws, thiab ob lub koob ntawm Mini LED backlight nti khoom, suav nrog 1021 thiab 0620, tau tsim.Nyob rau tib lub sijhawm, txhawm rau hloov kho kom zoo dua rau cov kev xav tau ntawm Mini COG ntim, Guoxing Semiconductor tau tsim cov khoom siv hluav taws xob 0620 tshiab, muab cov neeg siv khoom nrog ntau txoj kev xaiv.

3, Cov yam ntxwv ntawm Mini LED backlight nti

1. High sib xws epitaxial qauv tsim, muaj zog anti-static muaj peev xwm ntawm cov nti

Txhawm rau txhim kho lub wavelength concentration ntawm Mini LED backlight chips, Guoxing Semiconductor txais ib qho tshwj xeeb epitaxial txheej kev ntxhov siab tswj tshuab los txo cov kev ntxhov siab sab hauv thiab xyuas kom muaj kev sib xws hauv quantum zoo txoj kev loj hlob.Nyob rau hauv cov nqe lus ntawm chips, ib tug customized thiab siab txhim khu kev qha DBR flip nti tov yog siv los ua kom tiav ultra-siab anti-static muaj peev xwm.Raws li cov txiaj ntsig ntawm kev kuaj thib peb, qhov muaj peev xwm tiv thaiv zoo li qub ntawm Guoxing Semiconductor Mini LED backlight nti tuaj yeem tshaj 8000V, thiab kev ua haujlwm zoo li qub ntawm cov khoom mus txog qhov ua ntej ntawm kev lag luam.
