Iimpawu ze-Quantum kunye ne-LCD TV
Akungabazeki ukuba nangona kukho ukungaphumeleli , ii-TV ze-LCD zihlobo oluphezulu lweTV ezithengiswa kubathengi njengeziko lokuzonwabisa kwabo ekhaya. Ukwamkela ngokukhawuleza kwe-LCD TV ngokukhawuleza kukukhawuleza ukutshabalaliswa kwee-CRT kunye neTrans Projection TV kunye nesizathu esona sizathu sokuba i- Plasma TV ayisekho nathi .
Nangona kunjalo, i- OLED yeTV iqhutyelwa ngabaninzi, kunye nokusebenza kwayo "okuphuculweyo" njengelungelo eliyilandelayo kwiLCD. Enyanisweni, i-LG ibeke ukubheja kwayo kule teknoloji ngokuvelisa kwaye ikhuthaze ngokukhawuleza ii-TV ze-OLED.
Nangona kunjalo, ngokubaninzi nabaxhasi bangathanda ukucinga ukuba i-OLED imela inyathelo ekutyekhnoloji yeTV, ii-TV ze-LCD zisenokuthatha inotshi ngokubandakanywa kwama-Quantum Dots.
Iyintoni i-Quantum Dot?
Ngeenjongo zesicelo kwiiTV nakwividiyo, i-Quantum Dot yintsimbi eyenziwe ngumntu kunye nepropicuctor properties ezingasetyenziselwa ukukhulisa ukukhanya kunye nokusebenza kombala kuboniswe kwiimifanekiso ezisekhoyo kunye nevidiyo kwi-screen LCD.
Amanqaku e-Quantum ayinxalenye yeengqungquthela (ngokufana ne-phosphors kwi-TV ye-Plasma), kodwa, kulo mzekelo, xa bebetha ngeephotons ukusuka kumthombo wokukhanya ongaphandle (kwimeko yesicelo se-LCD TV i-Blue LED). kwendlela ethile yokuhamba, echanekileyo ngobukhulu bayo.
Amachashaza amakhulu akhipha ukukhanya okukhankanywe ebomvu, kwaye njengoko amachaphaza athola ukuba amancinci, akhipha ukukhanya okugqithiseleyo ekuhlaleni. Xa i-Quantum Dots yamanqanaba atyunjiweyo ihlanganiswe ndawonye kwisakhiwo (ngaphezulu kolu phepha kwiphepha elilandelayo) kwaye idibaniswe nomthombo wokukhanya weBluetooth LED, bayakwazi ukuphuma ekukhanyeni kuwo wonke umgca wombala ofunekayo wokubukela iTV. Ukusebenzisa izakhiwo ze-Quantum Dot, abenzi beTV bangakwandisa ukukhanya kunye nokusebenza kombala kwee-TV ze-LCD ngaphezu kwamandla akhona.
Umfanekiso ongasentla ubonisa isakhiwo se-quantum dot (ngakwesokudla), umzekelo wokuxhamla ulwalamano lwe-Quantum Dot kumgangatho wokungcoliswa kombala ngokusayizi (ngakwesobunxele), kunye nendlela i-Quantum Dots eyenziwa ngayo (ibukeka njengento kwi-lab yaseDransenstein okanye ebhokisini yekhemishi yobhaliso).
Iifomati ze-Quantum zinokusetyenziswa njani kwii-TV zeLCD
Emva kokuba ama-Dots of Quantum ayenziwe, amachashaza ahlukeneyo angasetyenziswe ngandlela-thile okanye ngohlobo oluhlelwe ngendlela ehleliweyo kwi-casing engafakwa kwi-TV ye-LCD (nge-TV ye-LCD amachaphaza aqhelekileyo amacandelo amabini, ayenzelwe ukuGrafi kunye elinye lilungiswe ngokuBomvu).
Umfanekiso oboniswe kweli phepha ubonisa indlela i-Quantum Dots ingasetyenziswa ngayo kwi-TV ye-LCD, ngokubhekiselele ku-casing type.
