Ukuqhutywa ngamaza wedijithali, intengiso yokubonisa yezorhwebo iye yajongana namathuba ophuhliso angazange ahlawulwe ngaphambili. Ngokukhula okuqhubekayo koqoqosho lwehlabathi kunye nokuphuculwa okuqhubekayo kwemfuno yemfuno yabathengi, isikali semakethi yolombozo sandise unyaka nonyaka, kunye nezinto zobugcisa ziye zavela kumjelo ongapheliyo. Ngakumbi, isicelo seUmboniso we-LEDItekhnoloji izise utshintsho lotshintsho kwimiboniso yorhwebo. Imibala yayo eqaqambileyo kunye nemifanekiso ecacileyo kukuwabela ngamehlo kwaye ube yinto entsha yentengiso.
Izikrini zokubonisa ezi-LED, ngokukhanya kwazo okuphakamileyo, ngokwahlukileyo, ubomi obude kunye nokusebenzisa amandla aphantsi, ngokuthe ngcembe, ngokuthe ngcembe ukuba yeyona nto iphambili kwiMiboniso yentengiso. Nokuba kwisithili sokuthengisa esiqhubela phambili, kwi-Lobby yehotele ephezulu, okanye kwibala lemidlalo elixineneyo, izikrini zokubonisa ezi-LED zitsalela ingqalelo yabantu malunga nefuthe lokungasebenzi. Ekuphuhliseni kwimakethi yokubonisa yezorhwebo, isisombululo seUmboniso we-LEDIzikrini zibe sisiseko esibalulekileyo somgangatho wokulinganisa. Ke, yintoni kanye kanye isisombululo sezikrini ze-LED, kwaye ibalwa njani?
Isisombululo sezikrini zokubonisa ezi-LED, ngamafutshane, linani leephikseli kwindawo ethe tyaba kwaye ethe nkqo kwiscreen. Ezi pixel zilungiselelwe kwifom ye-matrix, kunye nokwenza umfanekiso esibonayo kwiscreen. Isigqibo sichaphazela ngqo ukucaca komfanekiso kunye nencindi yomfanekiso. Isisombululo esiphezulu sithetha iiphikseli ezingaphezulu kwiscreen, esinokubonisa iinkcukacha ezithe kratya kwaye senze umfanekiso oqinisekileyo kwaye ucacile.
Xa ubala isisombululo seUmboniso we-LED, Izinto ezimbini eziphambili kufuneka zithathelwe ingqalelo: ubungakanani besikrini kunye ne-dot. I-DOT SPID, emgama phakathi kweephikseli ezikufuphi ezimbini, yenye yezona zinto zibalulekileyo ezichaza isigqibo. Incinci i-DoT Plate, iiphikseli ezingaphezulu zinokubekwa kwiscreen esifanayo nesisisombululo.
Makhe sithathe umzekelo ukubonisa indlela yokubala isisombululo. Masithi sinesiboniso se-LED ububanzi obuziimitha ezi-3 kunye nobude obuziimitha ezi-2, kunye ne-DOT FITT ye-10 mm (okt p). Emva koko, inani leephikseli kwindawo ethe tyaba liyinto yobubanzi bobubanzi obuxhaswa yi-DoT Pretch, yile: 3000 ÷ 10 = 300; Inani leephikseli kwindawo ethe nkqo kukho umkhuhlane wokufundisisi ohlulwe yi-DOT, oko kukuthi, 2000 ÷ 10 = 200. Ke ngoko, ukusonjululwa kwalo mboniso we-LEDIS ngama-300 × ama-200 eepikseli.
Ngokuphuhliswa okuqhubekayo kwemakethi yokubonisa yezorhwebo, abathengi banemfuno eziphezulu nezingaphezulu zesigqibo semiboniso ye-LED. Ukuboniswa okuphezulu kwesenzo kunokubonelela ngemifanekiso encinina kunye neenkcukacha ezityebileyo, ukwenza intengiso, iividiyo kunye nomnye umxholo onomdla ngakumbi. Kwangelo xesha, isisombululo esiphezuluIzikrini zokubonisa ezi-LEDyiba yindlela ebalulekileyo kumashishini ukubonisa umfanekiso wabo we-brand kwaye uphucule amava abathengi. Ukongeza, kunye nokuqhubela phambili kwetekhnoloji, i-DoT ye-Screen skshoni ye-LED iqhubekile nokuncipha kwaye isisombululo siqhubekile nokunyuka, ukuzisa amathuba amaninzi kwimakethi yokubonisa yezorhwebo. Ukusuka kwiBibyuli ye-Giant Ourdoon ukuya kwizikrini zokubonisa ii-Indoor ze-Indoor, izikrini zokubonisa ezikhokelwa zikhokelela kwintengiso yolombozo kunye nezibonelelo zazo ezifana nesisombululo esiphezulu, ukuqaqamba okuphezulu, kunye nenxalenye ephezulu.
Ngesishwankathelo, isisombululo seIzikrini zokubonisa ezi-LEDyenye yezalathi ezibalulekileyo zokulinganisa iziphumo zazo zokubonisa. Ngokuqonda ngenkcazo Kuphuhliso lwexesha elizayo lwentengiso yomboniso wezorhwebo, izikrini eziPhezulu zokuBoniswa zizixhobo eziPhezulu ziya kuqhubeka nokudlala indima ebalulekileyo kwaye zizise amava abonayo abonakalayo kubathengi kunye namashishini.
