LED Backlit Zaub: Nws Yog Dab Tsi & Nws Sib Piv
Lo lus "LED backlit zaub" tshwm nyob rau ntawm cov khoom specs thiab cov lus qhia tech, tab sis nws tsis yog ib txwm paub meej tias nws txhais li cas lossis nws txawv ntawm lwm hom zaub. Yog tias koj tab tom sim nkag siab txog dab tsi yog coj backlit zaub thev naus laus zis thiab nws cuam tshuam li cas rau kev ua tau zoo, phau ntawv qhia no muab rau koj ncaj qha, piav qhia siv tau.
Dab tsi yog LED Backlit Display?
LED backlit zaub yog lub tiaj tus - vaj huam sib luag npo uas siv LEDs (lub teeb - emitting diodes - semiconductor Cheebtsam uas tsim lub teeb thaum muaj hluav taws xob tam sim no dhau los ntawm lawv) raws li lub teeb ci uas ci ntsa iab LCD (Liquid Crystal Display) vaj huam sib luag los ntawm qab. Cov kua muaju nyob rau hauv LCD txheej modulate LED backlight los tsim cov duab ntawm lub vijtsam, tab sis cov LEDs lawv tus kheej tsis ncaj qha tsim cov duab - lawv muab lub teeb uas LCD txheej tswj thiab xim.
Qhov no yog thev naus laus zis tom qab feem ntau ntawm cov pav ca - vaj huam sib luag cov ntxaij vab tshaus muag niaj hnub no - TVs, computer monitors, laptop screens, tablets, and commercial signage panels. Thaum ib qho khoom lag luam tsuas yog "LED screen" hauv cov neeg siv khoom lag luam, nws yuav luag ib txwm muaj lub vijtsam coj rov qab - LCD zaub nrog LED backlighting - es tsis yog ncaj qha - saib LED zaub qhov twg LEDs lawv tus kheej tsim cov duab pixels.
Yuav ua li cas LED Backlighting Hloov Ua Ntej Technology
Ua ntej LED backlighting dhau los ua qauv, LCD panels siv CCFL (Cold Cathode Fluorescent Teeb - fluorescent raj siv los ua lub teeb pom kev hauv LCD ua ntej) backlights. Kev lag luam hloov mus rau LED backlighting rau cov laj thawj tswv yim: LEDs tso cai rau cov vaj huam sib luag slimmer, ncav cuag qhov ci ntsa iab tam sim ntawd yam tsis muaj qhov sov sov - lub sij hawm nce, feem ntau haus tsawg zog raws li kev ua haujlwm zoo, thiab tsis muaj mercury, uas cov teeb fluorescent xav tau thiab tsim cov kev txiav txim siab pov tseg.
Kev nkag siab txog dab tsi yog qhov LED backlit zaub hauv cov ntsiab lus ntawm qhov kev hloov pauv keeb kwm no qhia meej tias vim li cas txhua qhov niaj hnub LCD cov ntxaij vab tshaus yog "LED cov lus qhia" - vim tias lawv siv LEDs ua lawv lub teeb pom kev, txawm tias cov duab tsim tshuab tseem yog LCD.
Hom LED Backlit Display Configurations
Txoj hauj lwm thiab kev tswj ntawm LED backlight nyob rau hauv lub vaj huam sib luag cuam tshuam rau cov duab zoo:
| Kev teeb tsa | Nws ua haujlwm li cas | Cov yam ntxwv tseem ceeb |
|---|---|---|
| Ntug -lit LED | LEDs raws cov npoo vaj huam sib luag; lub teeb-cov lus qhia vaj huam sib luag kis illumination | Enables slim vaj huam sib luag profiles |
| Tag nrho -array LED | LEDs faib thoob plaws hauv qab ntawm lub vaj huam sib luag | Lub teeb pom kev zoo dua li ntug-lit |
| Tag nrho -array hauv zos dimming (FALD) | Tag nrho -array LEDs muab faib rau ntawm nws tus kheej dimmable zones | Txhim kho qhov sib piv; txo cov nyhuv halo |
| Mini -LED backlit | LEDs me me nyob rau hauv tuab puv -array; ntau thaj tsam dimming | Finer hauv zos dimming, ze rau OLED qhov sib piv |
Hauv zos dimming (ib qho txheej txheem uas ntu ntawm LED backlight tuaj yeem dim ntawm nws tus kheej los txhim kho qhov sib piv hauv qhov tsaus ntuj ntawm daim duab) yog qhov tseem ceeb tshaj plaws kev ua tau zoo sib txawv hauv cov coj backlit zaub qeb. Ntau thaj chaw dimming feem ntau tsim kev tswj qhov sib txawv zoo dua.
LED Backlit Display vs. Direct-Saib LED zaub
Ib qho ntawm qhov tsis meej pem yog qhov sib txawv ntawm LED backlit zaub thiab ncaj qha - saib LED zaub:
LED backlit LCD zaub:
LEDs ua lub teeb ci tom qab lub vaj huam sib luag LCD
Cov kua siv lead ua kua txheej tsim cov duab
Tsau vaj huam sib luag loj; tsis tuaj yeem seamlessly pobzeb ntawm cov nplai loj yam tsis muaj bezel khoob
Txheem rau cov neeg siv khoom siv hluav taws xob thiab kev lag luam kos npe ntawm kev ntsuas ntsuas
Feem ntau tus nqi ntau dua - siv tau rau ib cheeb tsam, tshwj xeeb ntawm kev daws teeb meem zoo
Direct- saib LED zaub:
LEDs yog cov duab - ua pixels lawv tus kheej; tsis muaj LCD txheej
Muaj peev xwm brightness rau sab nraum zoov siv
Modular thiab scalable rau qhov loj heev qhov ntev tsis pom bezels
Txheem rau kev lag luam loj loj, phab ntsa video, sab nraum zoov billboards
Feem ntau tus nqi siab dua ib chav tsev, tshwj xeeb tshaj yog nyob rau hauv qhov zoo pixel pitches
Rau feem ntau cov ntawv thov zaub txhua hnub, cov khoom siv hluav taws xob coj rov qab siv hauv cov khoom siv hluav taws xob thiab cov qauv kev lag luam kos npe tsim nyog. Direct- saib LED dhau los ua qhov kev xaiv tsim nyog rau loj - hom, siab - brightness, los yog seamlessly scalable installations.
Cov yam ntxwv ua tau zoo ntawm LED Backlit Displays
Contrast Performance
Qhov sib piv piv ntawm cov duab coj backlit yog cuam tshuam los ntawm qhov teeb meem zoo li cas tuaj yeem tswj tau. Yog tsis muaj qhov dimming hauv zos, lub teeb rov qab teeb pom kev tag nrho ntawm lub teeb ci zoo ib yam, lub ntsiab lus tsaus nti ntawm cov duab tseem tau txais lub teeb pom kev rov qab - txwv qhov sib piv zoo. Hauv zos dimming txhim kho qhov no los ntawm kev txo cov teeb pom kev hauv cov duab tsaus, txawm tias qee lub teeb los ntshav nyob ib puag ncig cov khoom ci ntawm qhov tsaus ntuj tseem tuaj yeem tshwm sim hauv kev siv yooj yim.
Xim raug
Xim raug nyob rau hauv LED backlit qhia nyob ntawm LED backlight spectrum thiab cov yam ntxwv ntawm LCD xim lim. Cov khoom lag luam ua lag luam rau xim- kev ua haujlwm tseem ceeb feem ntau qhia meej txog cov qauv xim xim (xws li sRGB lossis DCI-P3) thiab tej zaum yuav suav nrog lub Hoobkas calibration.
Brightness
LED backlighting tso cai rau ntau qhov kev ci ntsa iab uas haum rau qhov chaw sib txawv. Cov neeg siv khoom siv rau kev siv hauv tsev ua haujlwm ntawm qib qis qis. Tshwj xeeb siab -brightness versions ntawm LED backlit cov ntxaij vab tshaus muaj nyob rau lub qhov rais -fab los yog siab-ambient- teeb coj mus muag daim ntaub ntawv.
Thaum LED Backlit Display Technology yog qhov kev xaiv zoo
LED backlit zaub yog zoo haum rau:
