Thaum ntau tus neeg siv xaiv los hloov kho cov xim puv xim LED, lawv feem ntau tsis paub ntau txog cov ntsiab lus ntawm cov ntxaij vab tshaus LED. Raws li thawj qhov teeb meem ntawm LED cov khoom siv, nws yog qhov teeb meem ntawm qhov screen dot suab. Cia kuv piav qhia rau koj tias qhov txawv ntawm cov ntxaij vab tshaus nrog cov dot sib txawv yog dab tsi.
Thawj yog lub tswvyim ntawm tag nrho-xim LED loj-screen zaub. Feem ntau peb siv tsab ntawv Askiv P los qhia qhov loj ntawm qhov screen dot pitch. P los ntawm lo lus Askiv Point, uas txhais tau hais tias ib qho taw tes, thiab ntawm no sawv cev qhov kev ncua deb ntawm txhua qhov taw tes. Chav tsev ntawm qhov dot pitch ntawm LED screen yog mm (millimeters). Raws li lub npe qhia, P2 puv xim sab hauv tsev LED zaub ntaus ntawv qhia tias qhov kev ncua deb ntawm qhov chaw nruab nrab ntawm lub teeb hlaws yog 2 hli.
Yog li cov lus nug yog, qhov txawv ntawm qhov puv xim LED zaub loj npo P2 thiab P3 yog dab tsi? Piv txwv li, lub dot pitch ntawm P3 yog 3 hli, thiab lub dot suab ntawm P2 yog 2 hli. Yog li ntawd, nyob rau hauv tib lub tshuaj ntsuam cheeb tsam thiab qauv, P2 cov zaub dot pitch yog me dua, yog li cov duab tso tawm yuav nthuav dav dua thiab siab txhais. Nyob rau tib lub sijhawm, qhov me me ntawm qhov dot pitch, tus nqi siab dua. Tab sis nws tsis tau txhais hais tias qhov me me ntawm qhov dot pitch yog, qhov zoo dua, nws yuav tsum tau txiav txim siab raws li daim ntawv thov tiag tiag. Piv txwv li, sab nraum zoov puv xim LED zaub loj screen. Vim yog qhov pom kev deb, ib qho khoom siv nrog qhov sib txawv loj dua feem ntau yog siv. Piv txwv li, lub vijtsam zaub uas muaj qhov sib nrug loj dua li P3.91 LED zaub yog qhov tsim nyog rau kev siv sab nraum zoov. Ntawm cov neeg siv. Rau cov neeg siv uas xav tau cov lus qhia ntxaws ntxaws xws li kev saib xyuas kev nyab xeeb, cov xim puv xim me me-pitch LED cov ntxaij vab tshaus yuav tsim nyog dua.
Cov saum toj no yog hais txog qhov ntsuas qhov sib txawv ntawm cov xim puv xim LED zaub loj, Kuv vam tias nws tuaj yeem pab tau rau koj uas tab tom npaj yuav ib qho LED zaub.
