Amatara yinyuma yerekana ikoreshwa rya LED (urumuri rusohora diode) nkisoko yinyuma yerekana ibintu byerekana amazi ya kirisiti, mugihe urumuri rwa LED rwerekana gusa urumuri rwinyuma rwamazi ya kirisiti yerekana ibintu biva mumatara gakondo ya CCFL akonje (bisa n'amatara ya fluorescent ) kuri LED (urumuri rusohora diode).Ihame ryerekana amashusho ya kirisiti yamazi irashobora kumvikana gusa nkukuri ko voltage yo hanze ikoreshwa muguhindura molekile ya kirisiti ya kirisitu izahagarika umucyo wumucyo utangwa numucyo winyuma nkurugi, hanyuma ugashyiraho urumuri kumashusho yamabara atandukanye. amabara kugirango akore ishusho.

Amatara yaka LED

Itara ryaka rya LED ryamatara ni ugutegura LED ipfa kuruhande rwa ecran ya LCD, hanyuma igahuza icyapa kiyobora urumuri, kugirango mugihe moderi yinyuma ya LED isohora urumuri, urumuri rusohoka ruva kumpera ya ecran rwoherezwa kuri hagati rwagati ya ecran binyuze mumucyo uyobora urumuri., Kugirango umubare rusange wumucyo winyuma, wemerera ecran ya LCD kwerekana amashusho.

Iterambere rya Edge-yaka LED inyuma

Hamwe niterambere rihoraho ryikoranabuhanga, urumuri rwinyuma rwa LED ruzatera imbere kuva LED imwe kumurongo wo hejuru no hepfo kugeza kumurongo wanyuma umwe.Mubisanzwe, TV imwe ya LED isubira inyuma kumpande zombi za 32 "zishobora kugaragara kumasoko zikoresha LED zigera kuri 120 kugeza 150. Niba itara rya TV ryahinduwe rikaba LED imwe, umubare wa LED urashobora kugabanuka ukagera kuri 80-100 ( amaherezo ashobora kugabanuka Umubare wa LED uterwa nubuhanga bwikirango) Niba ikoranabuhanga rihuye, mugihe kiri imbere, LED imwe izahindurwa kuva kuruhande rurerure (hejuru cyangwa hepfo) yerekeza kuruhande rugufi (ibumoso cyangwa iburyo) ). Ubu bwoko bwimpinduka buzakoresha LED Umubare muto wibice.

Kwagura ubuzima

Kugabanya ikoreshwa rya LED ntabwo bigira ingaruka nziza mugucunga ibiciro, ariko tunabona izindi ngaruka nziza kuri module.Kurugero, ubushyuhe bwa module buzagabanuka kubera gukoresha LED nke.Dufashe urugero 32 "LCDTV nkurugero, gukoresha gake umubare wa LED birashobora kugabanya ubushyuhe bwa module hafi 10% -15%. Nubwo tudashobora kubara muburyo bwa siyanse umubare ushobora kongera igihe cyibice bya elegitoroniki, cyangwa ndetse na TV, uhereye muri rusange, kugabanya ubushyuhe bigomba kugira ingaruka nziza mubuzima bwibice bya elegitoronike.Iyi mfashanyo iragaragara cyane ahantu hanini LED yerekana amatara, kuko hariho LED nkeya zikoreshwa gake.

Inguni yo kureba

Mubyongeyeho, ikoreshwa ryibikorwa byo hejuru byongera imbaraga za firime ibisubizo nabyo bigira uruhare runini muburyo bwo kureba TV.Kuberako ihame rya tekiniki ya firime yohejuru yokwongerera imbaraga firime ni ugukwirakwiza urumuri rwa polarize kumurongo winyuma kugirango ruzenguruke kandi rugaragaze kugeza rwinjiye mubirahure.Moderi yinyuma ikoresha firime yongerera imbaraga urumuri iteza imbere hafi 30% ugereranije na module idakoresha firime optique.Kubera ko firime ikora cyane yerekana amashusho atandukanye na firime rusange ya prism, ntabwo ikeneye kwigomwa impande zose zo kureba kugirango yongere umucyo, bityo firime nkiyi yo hejuru cyane yo kongera umucyo irakundwa cyane nabakora televiziyo yo murugo no mumahanga.Hamwe n'akarere kiyongera kuri LCDTV, abaguzi batangiye kugira ibyo basabwa kugirango barebe inguni.47 "TV LCD ifite santimetero zirenga 10,000 zishyirwa hagati yicyumba. Birumvikana ko umuyobozi wurugo yizera ko abashyitsi bicaye ku mpande zose bashobora kwishimira ubuziranenge bwa ecran ya TV.

Kuzigama ingufu no kuzigama ingufu

Birumvikana ko rubanda rushobora kwibonera neza inyungu zamatara ya LED yamurika, aribyo kugabanuka kumikoreshereze rusange ya TV.Ubusanzwe 32 "LED yamurika TV, urwego ruriho ubu rutwara hafi 80W. Uru rwego ruhwanye nurwego rwa gatatu murwego rwo hejuru rwo gukoresha ingufu zigihugu.

Niba abayikora bashaka kunoza ibipimo ngenderwaho bikoresha ingufu za TV, hariho ibisubizo byinshi bihuye, ariko gukoresha firime yo hejuru cyane yo kongera umucyo bigomba kuba inzira yoroshye kandi itaziguye kandi ifatika yo kunoza imikorere yo gukoresha ingufu.Niba uhujwe na firime ikora cyane yo kongera imbaraga, gukoresha ingufu birashobora kugabanukaho hafi 20% -30% mugihe ukomeje urwego rumwe rwurumuri (imikorere yanyuma biterwa nikoranabuhanga rya buri kirango).Uhereye ku mibare, gukoresha ingufu za TV birashobora ahanini kunozwa kuva kuri 80W kugeza kuri 60W binyuze muri firime ikora cyane.Iterambere ry’imikoreshereze y’ingufu ntirishobora gusa gukora inganda gukora cyane na politiki y’igihugu yo kurengera ibidukikije, ahubwo ifasha n’abaguzi kwishyuza amashanyarazi bijyanye.

Duhereye ku isesengura rya tekiniki yavuzwe haruguru, turabona ko igishushanyo mbonera cyamatara yinyuma gifite akamaro kanini kubakora n'abaguzi.Mugihe cya vuba, urumuri-rumuri rumwe rukumbi LED igomba kuba iherezo ryamatara ya LED.
