Iftiinka dambe ee LED waxa loola jeedaa isticmaalka LED-yada (diodes-ka iftiimaya) oo ah isha dambe ee muraayadda dareeraha ah ee dareeraha ah, halka muraayadda dib-u-celinta LED-ku ay tahay isha dambe ee muraayadda dareeraha ah ee CCFL-ka caadiga ah ee iftiinka qabow (oo la mid ah nalalka fluorescent). ) ilaa LED (diode ifaya).Mabda'a sawirka ee crystal dareeraha ah waxaa si fudud loo fahmi karaa sida xaqiiqda ah in danab dibadda ah oo lagu dabaqay si loo leexiyo maaddooyinka crystals dareeraha ah ayaa xannibi doona daahfurnaanta iftiinka iftiinka dambe ee ka soo baxa sida albaabka, ka dibna iftiimiya iftiinka filtarrada midabka kala duwan. midabada si ay u sameeyaan sawir.

Iftiinka dambe ee LED-ka cidhif- shiday

Iftiinka dhabarka ee cidhifka leh waa in la habeeyo LED-ku oo ku dhinta hareeraha shaashadda LCD, ka dibna la jaan qaada saxanka hagaha iftiinka, si marka moduleka dambe ee LED uu iftiimiyo iftiinka, iftiinka ka soo baxa cidhifka shaashadda ayaa loo gudbiyaa aagga dhexe ee shaashadda iyada oo loo marayo saxanka hagaha iftiinka., Si tirada guud ee iftiinka dhabarka, u oggolaanaya shaashadda LCD inay soo bandhigto sawirro.

Horumarinta iftiinka dambe ee LED-ka ee Edge

Horumarka joogtada ah ee tignoolajiyada, iftiinka dambe ee dhinaca-dhinac-dhinaca LED wuxuu ka soo baxayaa hal LED oo ku yaal dhinacyada sare iyo hoose ilaa kan ugu dambeeya ee hal dhinac ah oo LED ah.Guud ahaan, TV-ga kaliya ee LED-ka ah ee labada dhinac ee 32 "kaas oo lagu arki karo suuqa wuxuu isticmaalaa qiyaastii 120 ilaa 150 LEDs. Haddii nalka dambe ee TV-ga loo beddelo hal LED, tirada LED-yada waxaa lagu dhimi karaa 80-100 ( taas oo aakhirka la dhimi karo Tirada LED-yadu waxay ku xidhan tahay tignoolajiyada sumada ah, hadii tignoolajiyada la is waafajiyo mustaqbalka la saadaalin karo, hal LED ayaa laga rogi doonaa dhinaca dheer (kor ama hoos) una rogi doona dhinaca gaaban (bidix ama midig). Isbedelka noocaan ah wuxuu isticmaali doonaa tiro yar oo walxo LED ah.

Kordhinta nolosha

Yaraynta isticmaalka LED-yada ma aha oo kaliya inay saameyn togan ku leedahay xakamaynta kharashka, laakiin sidoo kale waxaan aragnaa saameyno kale oo wanaagsan oo ku saabsan qaybaha.Tusaale ahaan, heerkulka moduleka waa la dhimi doonaa sababtoo ah isticmaalka yar ee LED-yada.Haddii aan tusaale u soo qaadano 32-inch LCDTV ee kor ku xusan, isticmaalka yar ee tirada LED-yada waxay hoos u dhigi kartaa heerkulka moduleka qiyaastii 10% -15%. Xataa TV-yada, sida guud ahaan, hoos u dhigista heerkulka waa in ay saameyn togan ku yeelato nolosha qaybaha elektaroonigga ah, caawimadani waxay aad uga caddahay aagga weyn ee TV-yada iftiinka dambe ee LED, sababtoo ah waxaa jira LEDs yar oo si dhif ah loo isticmaalo.

xagal daawasho balaadhan

Intaa waxaa dheer, isticmaalka xalalka kor u qaadista dhalaalka sare ee waxqabadka sare waxay sidoo kale door wanaagsan ka ciyaaraan xagasha daawashada TV-ga.Sababtoo ah mabda'a farsamada ee wax-ku-oolnimada sare-u-qaadista filimka kor u qaadista iftiinka ayaa ah in la gudbiyo iftiinka polarized ee moduleka iftiinka dambe si uu u wareego oo u muujiyo ilaa uu ka soo galo muraayadda.Module-ka iftiinka dambe ee isticmaala filimka kobcinta dhalaalka wuxuu hagaajiyaa dhalaalka qiyaastii 30% marka la barbar dhigo moduleka aan isticmaalin filimka indhaha.Maaddaama filimka kor u qaadista dhalaalka ee waxqabadka sare uu ka duwan yahay filimka guud ee priism, uma baahna in la huro xagasha daawashada si loo kordhiyo iftiinka, sidaas darteed filimka kor u qaadista dhalaalka sare ee noocan oo kale ah ayaa aad caan u ah shirkadaha TV-ga gudaha iyo dibaddaba.Iyada oo aagga sii kordhaya ee LCDTV-yada, macaamiishu waxay bilaabeen inay helaan shuruudo gaar ah oo loogu talagalay daawashada xaglaha.47-inch LCD TV oo leh in ka badan 10,000 inji ayaa la dhigayaa bartamaha qolka fadhiga. Dabcan, madaxa qoysku wuxuu rajeynayaa in martida fadhiya xagal kasta ay ku raaxaysan karaan tayada isku midka ah ee shaashadda TV-ga.

Badbaadinta tamarta iyo badbaadinta tamarta

Dabcan, dadweynuhu waxay si toos ah ula kulmi karaan faa'iidooyinka laydhka dambe ee LED-ka, taas oo ah dhimista isticmaalka guud ee tamarta TV-ga.Caadiga ah 32 "TV-ga dambe ee LED-ka, heerka hadda jira guud ahaan wuxuu isticmaalaa qiyaastii 80W. Heerkani wuxuu u dhigmaa heerka saddexaad ee heerarka waxtarka tamarta qaranka ee ugu dambeeyay.

Haddii wax-soo-saarayaashu ay rabaan inay hagaajiyaan heerarka isticmaalka tamarta TV-ga, waxaa jira xalal badan oo u dhigma, laakiin isticmaalka filimka kor u qaadida dhalaalka sare waa inuu noqdaa habka ugu fudud oo toos ah oo wax ku ool ah si loo hagaajiyo waxqabadka isticmaalka tamarta.Haddii lagu daro filimka kor u qaadista dhalaalka ee waxqabadka sare, isticmaalka tamarta waa la dhimi karaa ilaa 20% -30% iyadoo la ilaalinayo isla heerka dhalaalka (waxqabadka kama dambaysta ah wuxuu ku xiran yahay tiknoolajiyada calaamad kasta).Laga soo bilaabo xisaabinta nambarada, isticmaalka tamarta ee TV-ga asal ahaan waa laga wanaajin karaa laga bilaabo 80W ilaa 60W iyada oo loo marayo filimka kobcinta dhalaalka ee waxqabadka sarreeya.Hagaajinta isticmaalka tamarta kaliya uma ogola in warshaduhu ay si adag ula shaqeeyaan siyaasada ilaalinta deegaanka qaranka, laakiin sidoo kale waxay ka caawisaa macaamiisha biilasha korontada ee la xidhiidha.

Laga soo bilaabo falanqaynta farsamada ee kor ku xusan, waxaan aragnaa in naqshadeynta iftiinka dambe ee cidhifka ah ay faa'iido weyn u leedahay soosaarayaasha iyo macaamiisha.Mustaqbalka dhow, LED-yada hal dhinac ah ee cidhifka leh waa inay ahaadaan meesha ugu dambaysa ee laydhka dambe ee LED.
