Isemina Yezobuchwepheshe Mayelana Nokufaneleka KwePixel Pitch, Ibanga Lokubuka Kanye Nosayizi Wezibonisi ze-LED.

Ukufakwa kodonga lwevidiyo ye-LED kuyaqhubeka nokuguqula izikhala emhlabeni jikelele.

Amasonto, izikole, amahhovisi, izikhumulo zezindiza kanye nabathengisi bakha ukuzizwisa okunempilo, okuguquguqukayo, okukhumbulekayo ezindaweni ezihlukahlukene zasendlini nezangaphandle.

Uma ucubungula isibonisi se-LED, enye yezinketho zakho ezibaluleke kakhulu ukukhetha kokuphakama kwephikseli, kodwa ungase uzibuze, yini iphikseli yokuphakama? Ingabe ukuphakama kwephikseli kuzithinta kanjani izindleko? Yiziphi izinto ezibalulekile okufanele uzicabangele lapho ukhetha ukuphakama kwephikseli?

Lapha okwamanje, LetYonwaytechbheka ukuthi ungakwenza kanjani ukukhetha okulungile kwephikseli yakhoUdonga lwevidiyo ye-LEDiphrojekthi.

Okokuqala, Iyini imisindo ye-pixel?

Udonga lwe-LED luhlanganiswe ngaphandle kwamaphaneli e-LED, wona aqukethe amamojula amaningi e-LED. Lawa mamojula e-LED aqukethe amaqoqo e-LED noma amaphakheji e-LED, okungukuthi abomvu, aluhlaza okwesibhakabhaka nokuluhlaza okukhipha ukukhanya okuluhlaza (ama-LED) aqoqwe ngamaphikseli.

Ukuphakama kwephikseli yibanga eliphakathi nendawo ukuya maphakathi phakathi kwamaphikseli amabili, ngokuvamile elikalwa ngamamilimitha.

Uma unokuphakama kwephikseli engu-10mm, kusho ukuthi ibanga ukusuka enkabeni yephikseli eyodwa ukuya enkabeni yephikseli eseduze lingamamilimitha angu-10.

Okwesibili, Uyini umphumela we-pixel pitch kukhwalithi yesithombe sokuboniswa kwe-LED?

Ukuphakama kwe-Pixel kunquma ukulungiswa kwesibonisi se-LED, ubuncane bebanga lokubuka nebanga elingcono kakhulu lokubuka lesikrini se-LED.

Ukuphakama kwephikseli kuncane, iphikseli eyengeziwe futhi kuphumela emininingwaneni eyengeziwe kanye nekhwalithi yesithombe ephezulu.

Ngakho-ke uma udinga ukukhombisa izithombe ezinokulungiswa okuphezulu noma ividiyo kusibonisi sakho, udinga isibonisi se-LED esinokuphakama kwephikseli encane.

Isibalo esilandelayo sibonisa umphumela wephikseli kwikhwalithi yesithombe, ukuminyana kwamaphikseli amancane kuholela ekulungisweni okuphezulu nokuqukethwe okuningiliziwe.

Okwesithathu, ibanga lokubuka kufanele licatshangelwe uma wakha isibonisi esihle esiholelekile.

Ukuphakama kwephikseli kunquma ngokuqondile ukuminyana kwamaphikseli—inani lamaphikseli endaweni yesikrini esinikeziwe—futhi ukuminyana kwephikseli kunquma ngokuqondile ibanga elinconywayo lokubuka—ibanga elikude nodonga lwevidiyo okufanele umbukeli abe ngalo ukuze abukeke ngendlela egculisayo.

Lapho iphimbo licoleka, noma lincane, ibanga lokubuka liyasondelana.

Uma iphimbo lilikhulu, isibukeli kufanele sibe kude.

I-pitch iphinde ibe nomthelela ngokuqondile ezindlekweni, kodwa i-pixel enkulu esikrinini esiholwa usayizi omncane kanye nebanga elide lokubuka noma isibonisi esiholwa ngosayizi omkhulu kodwa ibanga elifushane lokubuka kokubili akukwazi ukuveza ukusebenza kwevidiyo okukhangayo.

Ukukhetha ukuphakama kwephikseli elungile kufanele kucatshangelwe izici ezimbili, ibanga lokubuka kanye nokulungiswa kwesithombe esidingekayo.

Amaphikseli amancane angcono ngaso sonke isikhathi futhi akulethela ikhwalithi yesithombe engcono kodwa, kubiza ngaphezulu.

Ungehlisa izindleko zokuthenga kwesibonisi se-LED usebenzisa iphikseli enkulu futhi usenekhwalithi yesithombe efanayo uma ibanga lokubuka lilide kunebanga lokubuka elingcono kakhulu.

Ibanga elingcono kakhulu lokubuka lokuphakama kwephikseli yibanga amehlo akho angeke esakwazi ukulithola phakathi kwe-pixel uma uya kude.

Izindlela zokubala zokukhetha okufanelekile kwesibonisi se-LED.

Njengoba kuchaziwe ngenhla, ukuphakama kwe-pixel kuwukucatshangelwa okukhulu kwale nqubo. Ihambisana nezinye izici ezinjengosayizi wokuboniswa, ibanga lokubuka, izimo zokukhanya ezizungezile, isimo sezulu nokuvikelwa komswakama, imidiya eqhudelanayo, ukusebenza kwemiyalezo, ikhwalithi yesithombe nokunye okuningi.

Izibonisi ze-LED ezifakwe kahle zinamandla okukhulisa ithrafikhi, ukuthuthukisa ukubandakanyeka kwezithameli, nokuthuthukisa ulwazi lwamakhasimende. Kodwa ukuqonda ukuthi ubuchwepheshe buzoba nomthelela kanjani kubo bobabili isibukeli kanye nesihloko sakho ngaphambi kokutshala imali kungakunika amandla okwenza isinqumo esingcono kakhulu sezidingo zakho ezithile kanye nesabelomali.

Izinga lokulinganisa elinzima lemininingwane yakho njengoba lingezansi:

Ibanga elincane lokubuka: 

Ibanga elibonakalayo lesikrini se-LED(M) = Iphikseli Pitch ( mm ) x1000/1000
Ibanga lokubuka elingcono kakhulu:

I-LED ibonisa ibanga elingcono kakhulu lokubuka(M)= I-Pixel Pitch ( mm ) x 3000~ pixel Pitch ( mm ) /1000
Ibanga lokubuka elikude kakhulu:

Ibanga elikude kakhulu (M)= Ubude besikrini sokubonisa i-LED ( m ) x izikhathi ezingu-30

Ngakho-ke ngokwesibonelo, isibonisi esiholayo se-P10 kububanzi obuyi-10m ngobude obungu-5m, ibanga lokubuka elingcono kakhulu lingaphezu kuka-10m, kodwa ibanga eliphakeme lokubuka lingama-150meters.

Uma ungaqiniseki mayelana nokuphakama kwephikseli okulungile ongakusebenzisa kuphrojekthi yakho ye-LED, CONTACTYonwaytechIsibonisi se-LED manje futhi sizokukhomba endleleni efanele. Phinda uhlole kaningi ukuze uthole izihloko eziwusizo kakhulu.
