Maxaa A TV-yada TV ah dhab ahaantii yahay
Waxaa jiray waxyaabo badan oo ah jaahwareer iyo jaahwareer ku wareegsan suuq-geynta "LED" TV-yada. Xitaa dad badan oo wakiilada xiriirka dadweynaha iyo xirfadleyda iibiya ee si fiican u yaqaanaan waxay been yihiin sharaxaadda waxa LED Television u yahay macaamiishooda mustaqbalka.
Si aad u qorto diiwaanka tooska ah, waxaa muhiim ah in la ogaado in ujeedada loo yaqaan 'LED' ay tilmaamayso nadaamka dhabarka ee loo isticmaalo Telefishannada LCD-ka ee badan, ma aha jajabyada soo saara sawirka muuqaalka.
Chips LCD iyo pixels ma keenaan iftiin u gaar ah. Si ay telefishanka LCD u soo saaraan sawir muuqaal ah oo ku saabsan shaashadda TV-ga, pixel-ka waa inay noqdaan "backlit". Wixii faahfaahin dheeraad ah oo ku saabsan geeddi-socodka dib-u-eegista ee loogu baahan yahay Telefishinka LCD, tixraac qodobkayaga : Demystifying CRT, Plasma, LCD, iyo DLP Television Television .
Marka ay asal ahaan yihiin, TV-yada waxay weli yihiin TV-yada LCD. Farqiga u dhaxeeya labada, sida kor ku xusan, waa habka dhabarka ee loo isticmaalo. Inta badan TV-yada waxay u shaqeeyaan ileyska LED-yada halkii ay ka muuqan lahaayeen nalalka florescent-ka, taas oo tixraac u ah LED-ga xayeysiisyada TV-ga.
Si aad u noqoto mid farsamo ahaan, TV-yada LED'ga waa in la calaamadiyaa loona sheegaa sida LCD / LED ama TV'yada LED / LCD.
Sidee LED Tijaabada loogu Isticmaalo TV-yada LCD
Waqtigan xaadirka ah waa laba siyaabood oo muhiimka ah ee LED-ga laydhka loo adeegsado telefishanada qolalka LCD .
Iftiinka LED-ka
Nooc ka mid ah iftiinka LED-ga ayaa loo yaqaan ' Edge Lighting' .
Nidaamkan, LEDs taxane ah ayaa la dhigaa geesaha dibedda ee LCD-ka. Iftiinka ayaa markaa ka dib la isticmaali doonaa shaashadda iyada oo la adeegsanayo "iftiimiyayaal iftiin" ama "hagayaal fudud". Faa'iidada qaabkani waa in LED / LCD TV laga dhigi karo mid aad u khafiif ah. Dhinaca kale, faa'iido la'aanta iftiinka Edge waa in heerarka madow aanay ahayn kuwo qotodheer iyo goobaha geeska ee shaashadda waxay u nugul yihiin inay noqdaan kuwo ka sii fiican goobaha muraayadda.
Sidoo kale, mararka qaarkood waxaa laga yaabaa inaad aragto waxa loo yaqaan "indho indhayn" ee geesaha shaashadda, iyo / ama "blotches cad" oo ku kala firirsan shaashadda. Marka aad fiirinayso iftiinka dayrka ama iftiinka gudaha, saameyntani badanaa lama ogaan karo - Si kastaba ha ahaatee, waxay noqon karaan kuwo la dareemo heerar kala duwan, marka habeenkii ama mugdi madadaalo ah barnaamijka TV-ga ama filimka la eego.
Nalalka toosan ee LED
Nooca kale ee laydhka LED-ga ayaa loo yaqaan " Direct or Full Array" (sidoo kale waxaa loo yaqaan 'LED Full') .
Qaabkan, dhowr digrii oo LED ah ayaa la dhigayaa gebi ahaanba shaashadda. Faa'iidada ugu weyn ee laydhka guud ee dhejiska ah waa sida ka duwan laydhka iftiiminta, Habka Tooska ah ama Qaabka guud, wuxuu bixiyaa xitaa xitaa, lebiska, madow ee guud ahaan shaashadda oo dhan.
Faa'iido kale ayaa ah in qalabkani uu shaqaaleyn karo "degsiimid degaanka" (haddii uu fuliyo soo saaraha). Aruurinta Buuxda ee Isku-dhafan oo ay weheliso Xasilinta Deegaanka waxaa sidoo kale loo yaqaan FALD .
Haddii TV-ga / LCD-ga loo yaqaan 'Direct Lit', tani macnaheedu waa inaan ku darin degelka degaanka, haddii aysan jirin tilmaame dheeraad ah. Haddii TV-yada LED / LCD ay ku jirto dhexdhexaadinta maxalliga ah, waxaa badanaa loo yaqaan 'Back Arrit Backlit Set' ama waxaa lagu qeexay sida Dhamaystiran ee Dakhliga Degmadda.
Haddii xajinta deegaanka la fuliyo, tani waxay ka dhigan tahay in kooxaha LED-yada la isu rogi karo oo laga goosan karo meelaha qaarkood ee shaashadda (mararka qaarkood loo yaqaano aagagga), sidaas darteedna bixiya koontarool badan oo iftiin iyo mug leh meel kasta, iyadoo ku xiran ilaha qalabka la soo bandhigo.
Kala duwanaansho kale oo ku saabsan isdabajooga baahsan oo leh xajmiga degaanka waa Sony's Blacklight Master Drive, oo ay ku soo bandhigtay tiro xadidan oo ah TV-yada sannadka 2016.
Kala duwanaanshahani wuxuu adeegsanayaa habka dhamaystiran ee aasaasiga ah ee aasaaskiisa, laakiin halkii loo isticmaali lahaa aagagga loo isticmaalo aagagga (kooxo pixels), dhabarka ilbiriqsi kasta oo madaxbanaan ayaa loo rogi karaa iyo dibedda, taasina waxay ku dari kartaa xitaa iftiin cad oo kala duwan iyo xakamaynta labadaba walxaha mugdiga ah ee madow - sida ciribtirka dhiig-baxa oo ka yimaada alaab dhalaalaya oo ka soo jeeda madow.
Hooshaqtada degaanka ee TV-ga LCD-Edge-Lit LCD
Si kastaba ha noqotee, waa in sidoo kale la tilmaamaa in qaar ka mid ah TV-yada laydhka / LCD-da ay sidoo kale sheeganayaan inay muujinayaan "xajmiga degaanka". Samsung waxay isticmaashaa ereyada yar-yar, Sony waxay loola jeedaa nooca farsamadan farsamadan sida LED-ga (oo ah TV-yada aan lahayn laydhka muraayadaha madow), halka Sharp ay ka dhigan tahay nooca loo yaqaan Aquos Dimming. Iyada oo ku xiran hadleeraha ereyada la isticmaalay way kala duwanaan kartaa. Si kastaba ha ahaatee, tiknoolijiyada la adeegsado waxay ka kooban tahay kala duwanaansho iftiin leh iyadoo la adeegsanayo iftiimayaasha iftiinka iyo hagaha iftiinka sidaas darteed way ka yar tahay habka tooska ah ee degaanka tooska ah ee loo isticmaalo Array Dhameystiran ama Muuqaal toos ah oo LED / LCD.
Haddii aad ka fekereyso inaad iibsato LED / LCD Telefishin, raadso nooca iyo moodooyinka ay hadda isticmaalaan habka Edge ama Full Array oo aad fiiriso nooc kasta markaad tageyso dukaanka si aad u aragtid nooca LED-ga ee kuugu muuqda adiga kugu haboon .
LED / LCD TVs iyo TV-yada LCD-ga ah
Laga soo bilaabo LED-yada ayaa loogu talagalay si ka duwan nidaamyada laydhka caadiga ah, taas macnaheedu waa in LCD-da cusub ee dib-u-qabatada LCD ay bixiyaan kala-duwanaanta soo socota ee kala duwan ee LCD-ga caadiga ah:
- Isticmaalka awoodda hooseeya.
- No Mercury waxaa loo isticmaalaa sida nidaamyada laydhka kale ee LCD.
- Midab badan oo isku dhafan oo midab leh.
- In TV-yada / LCD-da oo isticmaalaya habka laydhka dhaadheer buuxa, waxaa jira wax yar ama aan lahayn iftiin yar oo mugdi ah. Tani waxay ku kordhineysaa xitaa heerar madow oo ka fiican ta caadiga ah ama LED -ta LCD- ga ah ee LCD- ga.
- TV-yada LCD-ka ee u shaqeeya Dhameystirka Dhameystiran ama Meel Taageerada tooska ah ee LED-ka ah ayaa ka sii wayn TV-yada LCD-yada kuwaas oo ku shaqeeya ileyska iftiinka iftiinka LED-ka. Si kale haddii loo dhigo, TV-yada / LCD-da ee isticmaala habka laydhka "Edge" ayaa laga dhigi karaa mid ka sii fiican tan LCD-ga LCD-ga iyo Tilmaamyada Tilmaamaha LED / LCD-da.
TV-yada kaliya ee runta ah (oo aan la dhicin TV-yada OLED oo ah tiknoolajiyo kala duwan) ayaa ah kuwa aad ku aragto garoomada, arena, dhacdooyinka waaweyn iyo "boodhka sare". (Eeg tusaale ahaan).
Taageerada LED-ka waxay mataleysaa horumarinta tiknoolajiyadda, inta badan waxay keenaysaa LCD TV-yada u dhow Plasma Televisions marka la eego heerka waxqabadka madow, isla markaana, isla markaana, samaynta naqshadeynta LCD-ta ah ee dahsoon.
LEDs iyo Quantum Dots
Tiknoolojiyad kale oo lagu daro tiro sii kordhaysa ee TV-yada LED / LCD waa Quantum Dots. Samsung waxay ku xiran tahay TV-yada loo yaqaan "Quantum Dot-tech-TV" sida TV-yada QLED, oo dad badani ku wareersan yihiin TV-yada OLED - Si kastaba ha ahaatee, ha qummanayn, labada teknoolajiyadu ma aha oo keliya laakiin waa kuwo aan la isku halleyn karin.
Wareega, Qodobada Quantum waa nanoparticles oo nuuc laga sameeyay oo u dhaxeeya Edge Lit ama Nidaamka Dhexdhexaadinta tooska ah / Dhexdhexaad ah iyo Dibedda LCD. Quantum Dots designed to enhance the performance of the color beyond the LED / LCD TV soo saaro iyaga oo aan iyaga. Wixii faahfaahin ah oo ku saabsan sida Quantum Dots loo sameeyo, iyo sidoo kale sida, iyo sababta, loo isticmaalo ee TV / LCD TV, tixraac qodobkayaga Quantum Dhibcaha - Hagaajinta Hormarka LCD TV .
Isticmaalka LED Mashruuca DLP Video
Nalalka LED-ga ayaa sidoo kale ka dhigaya habka loo yaqaan ' DLP' video . Xaaladdan, LED waxay siisaa ilaha iftiinka halkii laga heli lahaa nalalka la saadaaliyay. Mashruuca DLP ee fiidiyowga, sawirka waxaa lagu soo saaraa foomka naxwaha leh ee dusha sare ee qalabka DLP, taas oo mid kasta oo pixel uu yahay muraayad. Ilaha iftiinka (sida xaaladdan iftiinka iftiinka LED-ka ee ka samaysan casaan, cagaaran, iyo buluug) waxay muujinaysaa iftiinka DLP ee micromirrors ee yaryar waxana lagu saadaaliyaa shaashadda.
Isticmaalka ileyska iftiinka iftiinka LED-da ee DLP-da ayaa ka gaabinaya isticmaalka birta midabka leh. Tani waxay kuu sahleysaa inaad aragto sawirka shaashadda iyada oo aan wax saameyn ah ku yeelan doonin qoob-ka-soo-saarka DLP (qoryaha roobabka yar yar ee mararka qaarkood lagu arki karo indho-indheynayaasha inta lagu jiro dhaqdhaqaaqa madaxa). Sidoo kale, maaddaama ilaha iftiinka iftiinka LED ee loogu talagalay laydhka laga dhigi karo mid aad u yaryar, waa nooc cusub oo fiidiyoow ah oo fiidiyoow ah, oo loo yaqaan 'light source light' ah oo ka shaqeeya barnaamijyada DLP ee fiidiyoowga ah ayaa baabi'inaya isticmaalka midabka midabka. Tani waxay kuu sahleysaa inaad aragto sawirka shaashadda iyada oo aan wax saameyn ah ku yeelan doonin qoob-ka-soo-saarka DLP (qoryaha roobabka yar yar ee mararka qaarkood lagu arki karo indho-indheynayaasha inta lagu jiro dhaqdhaqaaqa madaxa). Sidoo kale, tan iyo markii ilaysyada iftiinka LED ee loogu talagalay mashruucyada la samayn karo aad u yaryar, waa nooc cusub oo loogu talagalay mashruucyo fiidiyow ah, oo loo yaqaan Pico projectors ayaa noqday caan.
Isticmaalka Isticmaalka TV-yada - Hada iyo mustaqbalka
Tan iyo markii la jebiyey TV-yada Plasma , LED / LCD TV waxay hadda yihiin qaabka ugu badan ee TV-yada loo heli karo macaamiisha. TV-yada OLED, oo isticmaala tiknoolajiyo kala duwan, ayaa sidoo kale la heli karaa, laakiin xaddidan oo xadidan (Marka la eego 2017, LG iyo Sony waa kuwa kaliya ee TV-yada ka iibiya TV-yada OLED ee suuqyada Maraykanka), waxayna ka qaalisan yihiin laydhka LED / LCD. Iyada oo la naqshadeynayo sifooyinka, sida xajinta degaanka iyo Quantum Dots, waa cadaalad ah in la yiraahdo mustaqbalka LED / LCD TV waa mid aad u dhalaalaya.
