Luluphi udonga lwevidiyo, lusetyenziswa phi, iintlobo kunye nenjongo

Iindonga zevidiyo “ziiTV” ezihlanganiswe kwiiphaneli zeLCD ezifanayo, iiTV okanye iimonitha, ezidityaniswe kumfanekiso. Ngoku zisetyenziswa kwiinkalo zemfundo, ishishini, ukuzonwabisa – naphi na apho kukho imfuneko yokubonisa ulwazi kwisikrini esikhulu. Siza kukuxelela indlela iimodyuli zemodyuli ezilungiselelwe ngayo, indlela yokukhetha izixhobo ezikumgangatho ophezulu kwaye uzihlanganisele ngokwakho.

Umda weendonga zevidiyo

Ngokungafani nesikrini esilula okanye umfanekiso osuka kwiprojekti, iziboniso zodonga lwevidiyo zibonelela ngesisombululo esiphezulu, ukucaca kunye nemibala eqaqambileyo. Iimonitha zeendonga zevidiyo ziyakwazi ukufumana kunye nokusasaza umqondiso ngaxeshanye kwimithombo emininzi. Ngoko ke, zifanelekile ukusebenza kumagumbi anenani elikhulu labantu njengeyona nto isebenzayo. Iikhompleksi zevidiyo zifakwe apha:

1. amaziko okuthumela.
2. amaziko eemeko.
3. izifanisi.
4. Iinkampani zeTV kunye nerediyo.
5. Amagumbi eNgqungquthela.
6. iiholo zokufundisa, njl.

Injongo yeteknoloji

Ububanzi kunye nokuphakama kweendonga zevidiyo zifikelela, njengomthetho, ukuya kuthi ga kumashumi amaninzi eemitha. Abangaphambili beepaneli zodonga lwevidiyo babeyibhodi yamanqaku – ngokuchaseneyo, udonga lwevidiyo luncediswa yimisebenzi yomxholo wokulinganisa, ngokukhawuleza ukubonisa iingcamango ezintsha kwisikrini, ukusasazwa kwinani elingenamkhawulo lamashaneli, njalo njalo. Isilawuli sodonga lwevidiyo siyafuneka xa idatha ivela kwimithombo emininzi ngexesha elinye: inceda kwakhona ukutshintsha indawo yomfanekiso ngaphandle kwezakhelo zeepaneli zevidiyo zeLCD. Ukutshintsha isitishi okwenziwa ngesandla akufuneki xa usisebenzisa.

Kukho ii- mounts zodonga lwevidiyo : umgangatho, isilingi, udonga kunye nomgangatho ukuya phezulu.

Ukukhanya kulinganiswa kwi-candela ngemitha yesikwere, ixabiso elifanelekileyo eludongeni li-500. Kukho nezixhobo ezinokukhanya kwe-700-800 cd / m2, ezisetyenziswe kumagumbi anokukhanya okwandisiweyo.

Udonga oluqhelekileyo lwenziwe ngee cubes zevidiyo, ezithi, ngokuyila kwazo, zikwazi ukufikelela ngasemva okanye ngaphambili. Iityhubhu zihluka ngobukhulu ukusuka kwi-20 ukuya kwi-intshi ezili-100 ngokwediagonally. Zakhiwe kwipaneli yangaphambili ngendlela yokushiya izithuba ezingekho ngaphezu kwe-1 mm. Ukufikelela ngasemva kukuvumela ukuba unciphise umgama, kodwa i-front, ngokuchaseneyo, iyakwandisa ukuya kwi-2 mm kwaye inyuse iindleko zee cubes. Olunye ukhetho ziindawo zeLCD ezinomboniso wekristale elulwelo. I-gap phakathi kwezakhelo zeepaneli zikhulu kunaphakathi kweekhibhu zevidiyo – malunga ne-3-6 mm, kwaye nazo zingaphantsi kwazo ngokwemigaqo yokusebenza. Iiphaneli zeLCD zodonga lwevidiyo azikwazi ukusebenza iiyure ezingama-24 ngosuku kwaye kufuneka zicinywe iiyure ezingama-2-3,
Uhlobo lwesithathu luyi-LED panels kwiindonga zevidiyo, ezenziwe ngee-LEDs. Ubungakanani bepixel bunokufikelela kwi-3-5 mm, ngoko ke iimodeli ezinjalo zixhonywe ngaphandle njengoyilo lwentengiso. Ukukhanya kunye nokuzala kakuhle kombala kwenza ukuba kubonakale nakwimozulu embi. Ziziphi iimfuno zesixhobo:

• ubomi benkonzo ende obucwangcisiweyo (ukusuka kwiminyaka emi-3);
• ukungabikho komthungo – inkqubo ene-seams engaphezulu kwe-3.5 mm iya kuba yinto engenakwenzeka, ngaphezu koko, phantse akunakwenzeka ukuyibuyisela, kuba sele iphelile;
• iziqhoboshi kunye neengcingo zibandakanyiwe;
• ukufumaneka kwesiqinisekiso.

Iindonga zevidiyo-isishwankathelo sezona zinto zibalulekileyo:

Isixhobo sodonga lwevidiyo

Ukongeza kwimiboniso kunye nokunyuka, ikhithi kufuneka ibandakanye isixhobo esikwaziyo ukuthumela ulwazi kwisikrini. Ukuba kukho umthombo omnye kuphela, ngoko unokuwuxhuma ngaphandle kwezixhobo ezongezelelweyo: udonga ngalunye lunokutshintsha kwalo, ngoko kwanele ukudibanisa intambo kwikhonkco kunye nokudlulisa umfanekiso. I-HDMI eqhelekileyo, i-Display Port, i-VGA kunye nezinye iingcingo ziya kwenza. Xa usasaza ukusuka kumajelo amaninzi kunye nesidingo sokutshintsha phakathi kwabo, bathenga i-matrix switcher. Umgaqo wayo wokusebenza ulula: imithombo iguqulwa ngokucofa iqhosha kwi-remote control okanye utshintshe. Ikhebula lokudibanisa kufuneka likhethwe ngokusekelwe kwigalelo lothumelo – HDMI, DOP, VGA, njalo njalo.

Iprosesa yodonga lwevidiyo, ngenye indlela ebizwa ngokuba sisilawuli sevidiyo, ayikuvumeli kuphela ukuba usebenze ngamashaneli amaninzi ngaphandle kokulahleka komgangatho, kodwa ubonise abasebenzisi ababini ngexesha elinye, ukudlulisa amalungelo okulawula okanye ukulawula ukude. Iprosesa yevidiyo inemisebenzi emininzi kunabanye abalawuli, ngoko ifanelekile kumagumbi okulawula kunye nezithuba zokujonga.

Ukuzifakela udonga lwevidiyo, indlela yokwenza ukufakwa kwiimonitha ngezandla zakho

Ufakelo lwesiqhoboshelo

Ubunzima bezixhobo bufikelela kumaziko amaninzi, ngoko kunokuxhonywa kwikhonkrithi okanye kwizitena. Ukuba inkxaso ayinamandla ngokwaneleyo, umgangatho okanye umgangatho ukuya eludongeni okanye umgangatho ukuya phezulu kuya kwenza. Iintambo zombane ziyenziwa.

Ukunyuka

Okokuqala, i-rack ifakwe: iqulethe izibiyeli zetsimbi ezixhunyiwe ngokunqamlezayo. Iipaneli zifakwe phezulu, ukulungiswa kwenziwa – ukwenzela ukuba umgama phakathi kweefreyimu ube yincinci. Iziboniso ngokwazo zibuthathaka kwaye kufuneka ziphathwe ngononophelo. Ekugqibeleni, isixhobo siyajongwa kwaye silungiswe. https://youtu.be/7fMR_qJbYEk

Ulungelelwaniso kunye nohlengahlengiso

Zonke iimonitha zidityaniswe yisoftware enye, nangona kunjalo, ngaphandle koqwalaselo lwangaphambili, ayizukuqala. Indlela yokumisela ixhomekeke kuhlobo lomboniso. Ukuba umfanekiso uya kunikezelwa ngobubanzi obupheleleyo, kuyacetyiswa ukuba usebenzise iinkqubo ezifana ne-Enplug (https://www.enplug.com/) okanye Umsebenzisi (https://www.userful.com/). Nganye inee-microcomputer zayo kunye nezicelo. Into nganye iqhagamshelwe kwi-switcher – inkqubo ibonisa ngokuzimeleyo iziqwenga zevidiyo kwaye inikezela ukulinganisa. Ukuba iprojekthi yakho idinga ukubonisa imifanekiso eyahlukeneyo kwizikrini ezahlukeneyo, awuzukufuna mlawuli. Iimonitha zixhunyiwe ngokuthe ngqo kwimithombo, nganye yazo iqwalaselwe ngokuthe ngqo kwisicelo. Isoftware ekhethekileyo yekhompyuter kuhlobo lwesibini loqwalaselo alufunwa.

Iindonga zevidiyo LG

Kwizixeko ezikhulu zaseRashiya, iindonga ze-LG zinokuodolwa phantse kuyo nayiphi na ivenkile yehardware. Eyona nto idumileyo yi-2×2 kunye ne-3×3 ukucwangciswa kunye ne-diagonals ye-110 okanye i-intshi ye-160. I-gap encinci ye-seam phakathi kwabalawuli yi-0.88 mm kuphela – le yimodeli ye-LG V16508MWP. [caption id = "attachment_3860" align = "aligncenter" width = "355"]
LG V16508MWP

Iziboniso zine-software ye-SoC eyakhelwe-ngaphakathi evumela ukucwangciswa kunye nokulawula. Ii-LED azifuni izibane ezongezelelweyo: ukucaca kunye nokukhanya komfanekiso kukuvumela ukuba ufake iipaneli nangaphandle emini.

Iindonga zeVidiyo zakwaSamsung

I-Samsung ivelisa kwaye ithengise iindonga zokucwangciswa okuthandwayo (2×2, 3×3 kunye ne-4×4) kunye ne-diagonals ye-46 kunye ne-55 cm ngokusebenzisa abasasazi abasemthethweni. Inkampani iphuhlise imigca emitsha emininzi – UHD, UDE, UHF – eyahlula ngomgangatho ophezulu kunye neenkcukacha zomfanekiso. Ngokwesixhobo, iimonitha ze-Samsung LCD zibonelelwa ngeentambo zokudibanisa kunye nentaba yodonga. Ezi ndonga zibhekwa zingenamthungo: ubuncinci bemvume yi-1.7 mm, ubuninzi buyi-3.5.

Cubes Christie MicroTiles

Ubomi obucwangcisiweyo bokuboniswa kulo mvelisi ziiyure ezingama-65,000, oko kukuthi, malunga neminyaka eyi-7 ngaphandle kokuvala. Ukulungeleka kweetyhubhu kulele ekubeni nokwenzeka kweqela labo lasimahla. I-seam enobubanzi obungekho ngaphezu kwe-1 mm, iziboniso ezenziwe ngokusebenzisa i-DLP entsha kunye nobuchwepheshe be-LED – ezi zinani leenzuzo ze-Cubes zevidiyo ze-MicroTiles. Unokuzithenga kwiwebhusayithi esemthethweni yenkampani.

Iiphaneli eziSebenzayo ezininzi

Abo bafuna iindonga ezisebenzisanayo kufuneka banikele ingqalelo kwiimveliso zale nkampani. I-MultiTaction ikhuphe inkqubo esebenzisanayo yenkampani evuma ukufikelela kwiiphasiwedi, ixhasa amajelo onxibelelwano phakathi kwabasebenzisi, njalo njalo. I-MultiTaction iWall yeyona mveliso yabo ingcono, eyi-5-meter ububanzi kunye ne-2-meter ephezulu yodonga lwe-4×3 kunye ne-diagonals yeemodyuli ze-55 centimeters. Iziboniso zibonisa ngokulula umxholo kwizisombululo ukuya kuthi ga kwi-8K, ngokukhanya okukhulu kwe-500 cd/m2. Unokuthenga iindonga zevidiyo ngokusebenzisa abasasazi.
Iindonga zevidiyo zizixhobo ngaphandle kokuba umsebenzi wenkampani awukwazi ukucinga. Izixhobo zodonga zibiza, ngoko ngaphambi kokuthenga kubalulekile ukuziqhelanisa nokusebenza kwayo, iimeko zokusebenza kunye nesakhiwo, ukuze ungenzi ukhetho olungalunganga.
