Thola ukuthi yini okudingeka ukwazi nge-Quantum Dots (aka QLED)
I-Quantum Dots nama-TV e-LCD
Akungabazeki ukuthi naphezu kokushiyeka okuthile , ama-TV e-LCD yiyona ndlela evelele ye-TV ethengiswa kubathengi njengesizinda se-experience yabo yokuzijabulisa ekhaya. Ukwamukelwa okusheshayo kwe-LCD TV ngokusheshisa kwehlisa ukushona kwe-CRT ne- Rear Projection TVs futhi futhi isizathu esiyinhloko sokuthi ama-Plasma TV ayisekho nathi .
Kodwa-ke, i- OLED TV ihanjiswa abaningi, ngokusebenza kwayo "okuthuthukisiwe" njengomphathi ofanele ku-LCD. Eqinisweni, i-LG ibeke ukubheja kwayo kulobu buchwepheshe ngokukhiqiza nokugqugquzela ngentshiseko ama-TV e-OLED.
Kodwa-ke, njengabaphikisi abangase bathande ukucabanga ukuthi i-OLED imelela isinyathelo esiphezulu kwezobuchwepheshe be-TV, ama-TV e-LCD angakwazi ukuthatha inothi ngokufaka ama-Quantum Dots.
Iyini i-Quantum Dot?
Ngenhloso yesicelo kuma-TV nakubonisi bevidiyo, i-Quantum Dot iyi-nanocrystal eyenziwe ngomuntu enezakhiwo ze-semiconductor ezingasetshenziselwa ukukhulisa ukukhanya nokusebenza kombala okukhonjisiwe kumifanekiso namanje yevidiyo kusikrini se-LCD.
I-Quantum Dots yilezi zinhlayiya ezithinta amandla (okufana ne-phosphors ku-Plasma TV), kodwa, kulokhu, uma zishaywa ngamaphotons ukusuka kumthombo wokukhanya ongaphandle (uma kwenzeka kusetshenziswa i-LCD TV ukukhanya kwe-Blue LED), ichashazi ngalinye liveza umbala we-bandwidth ethize, enqunywa ubukhulu bayo.
Amachashazi amakhulu akhipha ukukhanya okubhekiswe ekubomvu, futhi njengoba amachashazi athola amancane, akhipha ukukhanya okubhekiswe ekukhanyeni. Uma ama-Quantum Amachashazi wezinkinobho ezikhethiwe ahlelwe ndawonye esakhiweni (ngaphezulu ngalokhu kukhasi elilandelayo) futhi ahlanganiswe nomthombo wokukhanyisa we-Blue LED, angafaka ukukhanya kuwo wonke umkhawulokudonsa wombala odingekayo ekubukeni kwe-TV. Ukusebenzisa izakhiwo ze-Quantum Dot, abenzi be-TV bangakwazi ukuthuthukisa ukukhanya nokusebenza kombala kwama-TV e-LCD ngaphezu kwamandla akhona.
Isithombe esingenhla sibonisa kokubili isakhiwo se-quantum dot (ngakwesokudla), isibonelo sokucabangela ubuhlobo be-Quantum Dot umkhiqizo wokukhipha umbala ngokuya ngobukhulu (ngakwesobunxele), nokuthi indlela i-Quantum Dots eyenziwa ngayo (ibukeka njengento ngaphandle kwebhulari likaDkt Frankenstein noma ekolishi chemistry lab).
Ama-Dot Quantum angasetshenziswa kanjani kuma-TV e-LCD
Uma i-Quantum Dots eseyenziwe, amachashazi afanayo ahlukene angafakwa noma ngokungahleliwe noma ngendlela ehlelwe ngobukhulu endaweni yokufaka isikhala esingafakwa ngaphakathi kwe-TV ye-LCD (ene-LCD TV amachashazi ngokuvamile amatshina amabili, elinye elilungiselelwe i-Green futhi enye ilungiselelwe i-Red).
Isithombe esiboniswe kuleli khasi sibonisa ukuthi i-Quantum Dots ingasetshenziswa kanjani ku-LCD TV, ngokusho kohlobo lwe-casing elisetshenzisiwe.
- Ifakwa ngaphakathi kwe-casing (ebizwa ngokuthi i-Edge Optic) emaphethelweni ephaneli e-LCD phakathi komthombo okhanyayo okhanyayo we-LED kanye nephaneli ye-LCD ( nge-TV ekhanyisiwe / i-LCD TV ).
- On "umcabango wokuthuthukiswa kwefilimu" obekwe phakathi komthombo wokukhanya we-Blue LED nephaneli ye-LCD (ye-Full Array noma i-Direct-Lit LED / i-LCD TV).
- Ku-chip ebeka phezu kwemithombo yokukhanya ye-Blue LED eceleni komkhawulo wephaneli ye-LCD (nge-TV ekhanyisiwe / i-LCD TV).
Ngendlela ngayinye, i-Blue LED ithumela ukukhanya ngokusebenzisa i-Quantum Dots, eyobe ijabule ukuze ikhishwe ukukhanya okubomvu nokuluhlaza (okuhlanganiswe ne-Blue okuvela emthonjeni wokukhanya we-LED). Ukukhanya okumibala okwehlukile kudlula phakathi kwe-LCD chips, ukuhlunga umbala, nokuya esikrinini sokubonisa isithombe. Isendlalelo esingeziwe se-Quantum Dot ivumela i-LCD TV ukuthi ibonise i- gamut enemibala eminingi egcwele futhi evulekile kunama-TV e-LCD ngaphandle kocingo olwengeziwe lwe-Quantum Dot.
