LCD vs Direct View LED Video Walls: Kodi Muyenera Kudziŵa
Ngati inu muli mu msika dongosolo zowonera, mwina anapeza kuti kanema khoma kusonyezedwa kubwera mu osiyanasiyana kuchuluka kwa akalumikidzidwa, masaizi, njira zamakono. Mukhozanso anaona kuti opanga ambiri amagwiritsa ntchito maina osiyana umisiri chimodzimodzi ndi kupanga zonena zotsutsana zimene luso amachita bwino.
M'pake kuti angalenge zambiri chisokonezo ogula. Kwa anthu ambiri, wina mfundo za chisokonezo ndi kusiyana pakati pa mitundu iwiri otchuka anasonyeza: "LCD" (limatchedwa "LED-LCD") ndi "Anatsogolera" (limatchedwa "Direct View anatsogolera"). Ngakhale kuti angafanane, LCD ndi Direct View kutsogozedwa ndi awiri anasonyeza umisiri osiyana ndi zizindikiro zawo osiyana ndi ubwino. Ndiyeno kodi phindu la zimenezi? Kodi zosiyana? Ngati inu akuvutika kuyankha mafunso amenewa, ife tiri pano kuti tikuthandizeni!
LCD
LCD (madzi galasi anasonyeza) ndi lathyathyathya gulu anasonyeza mtundu kuti wakhala wotchuka kwa zaka onse khoma kanema ndi ogula zamagetsi misika. N'kutheka kuti inu kale ntchito LCD luso kangapo patsiku - ndi mtundu anasonyeza ntchito mafoni kwambiri, oyang'anira computer, ndi zowonetsera kanema.
mapanelo LCD ndi lopangidwa ndi wosanjikiza galasi madzi sandwiched pakati pa zidutswa ziwiri za galasi magetsi. Madzi galasi ndi mankhwala amene amatuluka ngati madzi koma ali mamolekyulu kuti akhoza zochokera ngati timibulu. Pamene magetsi umagwiritsidwa ntchito timibulu madzi, makhiristo kuloza, kulola kuwala kudutsa kulenga chithunzi. timibulu madzi sabala kuwala awo, backlights imakonzedwa kumbuyo galasi pounikira kangoloko. LEDs (kuwala emitting diodes) ndi mtundu ambiri backlight ntchito lero, ndi ena opanga msika awo LCDs LED-backlit monga "LED-LCD."
LCDs chowala, angakwanitse, wodalirika komanso kupereka kwambiri zithunzi ntchito. LCD ndi luso kwambiri mkulu-kusamvana, kotero makoma LCD kanema angasonyeze lemba, zithunzi, kanema mwatsatanetsatane lakuthwa. Ubwino kupanga LCDs lalikulu mwina chifukwa osiyanasiyana ofunsira kanema khoma, m'zipinda m'manja mwa asilikali ku malo kafukufuku yunivesite.
Pamene LCDs ali tiled pamodzi kulenga khoma video, bezels (kapena matabwa) akalipo pakati pa mapanelo payekha. Tikhoza kuona ngati sangathe pamene kuyerekeza LCD kwa mitundu anasonyeza kosatayana ngati Direct View kutsogoleredwa. Komabe, opanga kuchepetsa bezel-m'lifupi ndi m'badwo uliwonse watsopano kusonyezedwa, kotero inu mudzapeza kuti bezels pa LCDs atsopano ndi zambiri osaonekera.
Direct View anatsogolera
Ngati LCD, Direct View anatsogolera (nthawi zina amatchedwa "anatsogolera") ndi lathyathyathya-gulu anasonyeza mtundu zokhudza ntchito kuwala emitting diodes (LEDs). Komabe, Direct View anatsogolera ntchito mosiyana kwambiri ndi LCD. Pa View Direct anasonyeza LED, mazana a LEDs zazing'onozi wokwera mwachindunji pa gulu, ndipo palibe galasi madzi kapena magetsi galasi ntchito. M'malo kutumikira monga backlight (monga iwo kuchita m'zinthu LCD), ndi LEDs mu Direct View LED kusonyezedwa kuonetsa zithunzi okha. Aliyense anatsogolera makamaka kakang'ono getsi kuti limatulutsa kuwala wachikuda pamene voteji makamaka umagwiritsidwa ntchito izo. Masango ofiira, zobiriwira, ndi buluu LEDs yagawidwa pa gulu la, polenga pixels ndi mitundu yoyenera kuti apange fano.
Direct View zinali kamodzi m'munsi-kusamvana anasonyeza mtundu ntchito makamaka m'zinthu chimphona panja, koma chitukuko cha LEDs ang'onoang'ono zisakuyenda apanga mwaubwino apamwamba zotheka. Izi patsogolo posachedwapa apanga Direct View LED yosangalatsa njira yatsopano malinga m'nyumba ya kanema.
Direct View LED mapanelo alibe bezels, kotero iwo akhoza tiled pamodzi kupanga kwathunthu kosatayana kanema khoma . Kusonyezedwa LED komanso chowala kwambiri, wodalirika mphamvu imayenera, ndi zabwino mtundu molondola ndi polimbikitsa chiwerengero cha mtundu uliwonse anasonyeza alipo lero. Makhalidwe amenewo Direct View LED ndi kusankha chabwino kwa zikuluzikulu digito signage ndi ntchito zina amafuna mkulu-amadza zithunzi.
Ngakhale mitengo akuyembekezeka kuchepa kwa zaka zikubwerazi, apamwamba-kusamvana LED makoma panopa kangapo mtengo kuposa LCDs, kotero njira imeneyi akadali patali chifukwa makasitomala ambiri. Komanso, ngakhale wapamwamba-kusamvana LED kusonyezedwa akadali sangathe kupereka kopitilira muyeso-mkulu mwaubwino kupezeka kwa LCD. Ntchito-milandu kuti amafunika chisamaliro kwa mfundo abwino, kusonyezedwa LCD angakhalebe mukonda.
Tikukhulupirira ife ndathandiza zingatithandize kumvetsa kusiyana - ndi ubwino wamba - a LCD ndi Direct View LED makoma kanema. Potsilizira pake, onse umisiri kwambiri anaonetsa, ndi kokha ntchito lanulo ndi ndondomeko angathe kudziwa njira yabwino kwa inu.
