LCD vs Direct View LED Video Walls: Me kana bukatar ka sani

Idan kana cikin kasuwar domin a gani tsarin, ka yiwuwa gano cewa, video bango nuni zo a cikin wani bewildering kewayon siffofi, masu girma dabam, da fasahar. Za ka iya kuma sun lura cewa, mutane da yawa masana'antun yin amfani da sunaye daban-daban domin wannan fasaha da kuma yin hus? Da'awar game da fasahar aikin mafi kyau.

Hakika, wannan zai iya haifar da wani yawa na rikice don masu saye. Ga mutane da yawa, daya musamman batu na rikice ne bambanci tsakanin biyu m nuni iri: "LCD" (wani lokacin ake kira "LED-LCD") da kuma "LED" (wani lokacin ake kira "Direct View LED"). Ko da yake su iya sauti kama, LCD da kuma Direct View LED ne biyu jinsin nuni da fasahar da nasu musamman fasali da kuma amfanin. Saboda haka, abin da sũ ne waɗanda amfanin? Ta yaya suka bambanta? Idan kana fafitikar da jawabi ga waɗanda tambayoyi, za mu yi a nan don taimaka!

LCD

Mene ne LCD?

LCD (ruwa crystal nuni) ne wani lebur panel nuni da irin abin da ya kasance m for shekaru a biyu da video bango da kuma mabukaci Electronics kasuwanni. Chances ne, ka riga amfani da LCD fasahar sau da yawa a rana - shi ke nuni da irin amfani a mafi wayoyin salula na zamani, kwamfuta zaune a yanki, da kuma telebijin fuska.

LCD bangarori an hada da wani Layer na ruwa crystal raini da tsakanin guda biyu da polarized gilashi. Liquid crystal ne wani abu da gudana kamar wani ruwa amma yana da kwayoyin da cewa za a iya daidaitacce kamar lu'ulu'u. Lokacin da lantarki ne amfani da ruwa lu'ulu'u, da lu'ulu'u matsawa, kyale haske zuwa ratsa don ƙirƙirar wani image. Liquid lu'ulu'u ba samar da nasu haske, don haka backlights aka shirya a baya da gilashi don haskaka nuni. LEDs (haske-emitting diodes) sun fi na kowa irin backlight amfani a yau, da kuma wasu masana'antun tallatar da LED-backlit LCDs matsayin "LED-LCD."

Abũbuwan amfãni daga LCD

LCDs ne mai haske, araha, abin dogara, kuma samar da kyau kwarai gani cika. LCD sigar musamman high-ƙuduri fasahar, don haka  LCD video ganuwar  iya nuna rubutu, hotuna, da bidiyo, a kaifi daki-daki. Wadannan abũbuwan amfãni yi LCDs mai girma zaɓi don wani fanni na video bango aikace-aikace, daga soja iko da dakuna zuwa jami'a cibiyoyin bincike.

Kai tsaye Duba LED

Abin da aka LED?

Kamar LCD, Direct View LED (wani lokacin kawai ake kira "LED") shi ne wani lebur-panel nuni da irin da ta shafi amfani da haske-emitting diodes (LEDs). Duk da haka, Direct View LED aiki sosai daban daga LCD. A wani Direct View LED nuni, daruruwan kankanin LEDs aka saka kai tsaye a kan wani panel, kuma babu ruwa crystal ko polarized gilashin da ake amfani. Maimakon hidima a matsayin backlight (kamar da suka yi a LCD nuni), da LEDs a Direct View LED nuni nuna hotunan da kansu. Kowane LED ne da gaske wani kankanin haske kwan fitila cewa fitarda launin haske a lokacin da wani musamman irin ƙarfin lantarki ne amfani da shi. Gungu na ja, kore, da shudi LEDs suna harhada a kan panel, samar da cikakken-launi pixels da ake bukata, don samar da wani image.

Direct View LED ya zarar wani m-ƙuduri nuni da irin amfani da yafi a giant waje nuni, amma ci gaban karami LEDs a 'yan shekarun nan sun yi yawa mafi girma shawarwari yiwu. Wadannan 'yan ci gaba sun sanya Direct View LED da farin ciki sabon zaɓi don na cikin gida video katangu.

Abũbuwan amfãni daga LED

Direct View LED bangarori da ba bezels, don haka za su iya a tiled tare samar da wata gaba daya  sumul video bango . LED nuni ne ma musamman mai haske, abin dogara, makamashi-m, kuma suna da mafi kyau launi daidaito da kuma refresh rates na wani nuni da irin samuwa a yau. Wadannan halaye sa Direct View LED mai kyau zabi ga manyan-sikelin dijital] aukar da kuma sauran aikace-aikace cewa bukaci high-tasiri visuals.

Disadvantages na LED

Ko da yake farashin da ake sa ran rage a cikin shekaru masu zuwa, mafi girma-ƙuduri LED ganuwar ne a halin yanzu sau da yawa fiye da tsada fiye da LCDs, don haka wannan fasaha ne har yanzu out of iya kai ga mafi abokan ciniki. Bugu da kari, har ma da mafi-ƙuduri LED nuni har yanzu ba zai iya samar da matsananci-high shawarwari samuwa daga LCD. Domin amfani da-lokuta da cewa bukatar da hankali ga mafi kyau cikakken bayani, LCD nuni iya har yanzu a fĩfĩta.

Muna fatan mun taimaka zubar da wasu haske a kan bambance-bambance - da na kowa amfanin - na LCD da kuma Direct View LED video katangu. Alal hakika, dukkanin ne m nuni da fasahar zamani, da kuma kawai ka takamaiman aikace-aikace da kuma kasafin kudin zai iya sanin ko mafi kyau zaži a gare ku.
