Los ntawm cov khoom siv los sib piv cov txiaj ntsig kawg ntawm cov khoom siv khoom siv yog qhov tseem ceeb tshaj plaws kev yuav khoom tus qauv, thiab cov khoom siv sib txawv yuav tsum muaj qee qhov zoo thiab qhov tsis zoo ntawm cov nyhuv, qhov kev sib piv tshwj xeeb LED zaub LCD splicing screen brightness siab nruab nrab qhov sib piv siab dav dav. Feem ntau, cov xim muaj xim siab nyob ntawm lub teeb ci.
Hais txog qhov ci ntsa iab, tsis tas yuav txhawj xeeb txog ob txoj kev siv thev naus laus zis tsis txaus. Ntawm qhov tsis sib xws, cov LEDs me me, uas paub txog lawv qhov ci ci siab, ntsib teeb meem ntawm kev ci ntsa iab. Ib qho ntawm cov txheej txheem kev lag luam tseem ceeb rau me me-pitch LEDs yog "qis qis." Nyob rau hauv sib piv, cov kua siv lead ua kua zoo li tsim nyog nyob rau hauv cov nqe lus ntawm brightness theem, thiab yog haum rau loj zaub screen daim ntaub ntawv. Nyob rau hauv cov nqe lus ntawm qhov sib piv Performance index, me me-pitch LED yog qhov siab tshaj plaws, thiab los ntawm qhov xav tau sab, qhov sib piv ntawm ob lub thev naus laus zis loj tshaj qhov xav tau tiag tiag cov zaub thiab qhov kev daws teeb meem ntawm tib neeg lub qhov muag. Qhov no ua rau qhov sib piv zoo, qhov zoo ntawm ob lub thev naus laus zis nyob ntawm ntau qhov kev ua kom zoo ntawm cov software, tsis yog qhov txwv tus nqi ntawm cov khoom siv.
Hais txog kev daws teeb meem, txawm hais tias me me-pitch LEDs tau tawg los ntawm, lawv tseem tsis tuaj yeem sib tw nrog LCD splicing. Tam sim no, tsuas yog cov kua siv lead ua kua tuaj yeem ua tiav qhov nrov ntawm 2K ntawm 55-inch units, thiab tsuas yog LCDs yuav tsum nrov 4K yav tom ntej. Rau me me-pitch LEDs, siab dua pixel ceev txhais tau hais tias qhov nyuaj ntawm kev ruaj khov tsim tau nce geometrically, lub pixel suab tau poob los ntawm 50 feem pua, thiab backplane ceev tau nce 4 zaug. Qhov no yog vim li cas vim li cas LEDs me me tau tawg los ntawm lub fwj ntawm 1.{{10}}, 0.8 thiab 0.6, tab sis tseem muaj tsuas yog 3.0, 2.5, thiab cov khoom zoo li no. hauv ntau daim ntawv thov. Tsis tas li ntawd, nws tsim nyog nco ntsoov tias "tus nqi tiag tiag ntawm pixel ceev kom zoo dua ntawm cov kua siv lead ua kua tsis meej", vim tias cov neeg siv tsis tshua xav tau qhov siab pixel ceev.
Cov xim ntau yog feem ntau tsis yog qhov kev txhawj xeeb tshaj plaws rau LCD splicing phab ntsa khoom. Ntxiv nrog rau cov ntawv thov xws li xov tooj cua thiab TV, kev lag luam phab ntsa splicing yeej tsis tau nruj raws li qhov kev thov rau xim luam tawm ntau yam. Los ntawm kev sib piv kev xav, me me-pitch LEDs yog ntuj dav-xim gamut khoom. Cov kua siv lead ua kua nyob ntawm lub teeb siv.
Cov xim daws teeb meem yog qhov kev pom tseeb ntawm cov xim ntau ntawm qhov sib piv ntsuas, thiab sawv cev rau lub peev xwm ntawm cov zaub kom rov qab xim thaum kawg. Tsis muaj ntau txoj hauv kev rau kev txiav txim siab ntawm qhov ntsuas no. Txawm li cas los xij, ntawm tag nrho, me me-pitch LEDs yuav tsum yog cov cuab yeej zoo tshaj plaws los ntawm kev tsim txiaj ntawm ob qhov zoo ntawm cov xim thiab qhov sib txawv.
LCD (luv rau Liquid Crystal Display) kua siv lead ua kua.
Cov qauv ntawm LCD yog tso cov kua siv lead ua kua cell ntawm ob qho tib si iav substrates. Lub khob sab hauv qab yog nruab nrog TFT, thiab lub khob sab saud yog nruab nrog cov xim lim. Lub teeb liab thiab qhov hluav taws xob ntawm TFT raug hloov los tswj cov kev taw qhia kev sib hloov ntawm cov kua siv lead ua kua molecules, yog li kom ua tiav lub hom phiaj los ntawm kev tswj xyuas seb lub teeb polarized ntawm txhua pixel taw tes tawm los yog tsis.
Lub teeb-emitting diodes tsuas yog hu ua LEDs. Nws yog tsim los ntawm cov tebchaw uas muaj gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), thiab lwm yam.
