Munguva ichangopfuura, kinescope TVs dzave dzanyangarika mumashure - hadziwanikwi mumagetsi emagetsi, kunze kwemamwe misha. Asi tetepa, mitambo yakamanikana haifaniri kufungidzirwa kunge yakasununguka zvachose uye inoshandiswa kwose kwose, uye mitsva yakagadzirwa nemhando yepamusoro inoshandiswa gore negore. Nokudaro, vanotengesa vatengi vanoona zvakaoma kusarudza pamusoro pokusarudza kokupedzisira kwe "bluji rebhuruu" pakati pehuwandu hwezvinhu zvakasarudzwa. Tichakuudza nezveTV yeTV uye zvigaro zvayo.
Chii chinonzi teknolojia yeTV?
Kazhinji LED ndiyo mutsara muChirungu, iyo inomirira "chiedza-emitting diode". Mutsara unoshandurirwa muchiRussia chete - LED. Uye kana tichitaura pamusoro pezvinorehwa neTV TV, zvadaro inogona kunzi LCD yakakurumbira.
Zvinonyatsozivikanwa kuti LC inyanzvi inoshandiswa pakushandiswa kwemvura yakadzika matrix. Ikokupedzisira ine mapepa maviri, pakati peiyo akaiswa makristuru emvura. Apo magetsi emagetsi anoshandiswa, anotanga kufamba. Asi nekuda kwezviedza zvemwenje pamatrix surface inosviba nerima uye mavara. Uye mafirita emavara, ari pasi pematrice, anoita chivara chemuvara pachikwangwani.
Nekupi kwechiedza chetambo che LED, ipapo nhamba huru ye LEDs inoshandiswa sechiedza chepachena (kusiyana neLCD backlight, umo magetsi anochera cathode fluorescent anoshandiswa).
Nokudaro, mutemo wekushanda kweTV yeTV inobva pakugadziriswa kwemakristuru emvura ematrikisi nema LED.
Kubatsira uye kusagadzikana kweTV
MaTV neTV teknolojia ane zvigaro zvakawanda. Zvichida, iyo inobatsira zvikuru ndiyo kushandiswa kwemagetsi kushandiswa: maererano nenyanzvi, kusvika ku40% zvichifananidzwa neLCD vatariri, umo mavhenekera anoitwa nemarambi e fluorescent.
Pamusoro pezvo, kutarisa kwe LED kunopinda zviri nyore mukati meimwe mukati-LED dzinogona kugadzira vataridzi kusvika 3-3.5 masikati masikati, nokuti chaizvoizvo ma LED ari maduku. Uye, iyi haisi muganhu. Nenzira, pane musiyano mune urongwa hwe LED pane maTV maTV, apo hutema hwematrix hunoenderana. Muchiitiko chacho pavanenge vakachengetwa kumashure kweTV panhare, vanoti kubva kuMotokari LED. Kutenda neizvi, chiedza chekona chinoitwa zvakafanana. Zvechokwadi wakanzwa nezveEdge yeTV yeTV. Kana zviri izvo Edge LED inopindira, iyo inonzi yakarongeka ye LEDs kumativi ose ekuyera kwekona pamwe nekushandiswa panguva imwe chete kwekuparadzira jenzura. Nokuda kweizvi, hupamhi yepaneti yakanyanya kudonhedzwa - inopfuura 3 cm! Nenzira, mumagetsi emagetsi kazhinji mune zvinyorwa zvemuenzaniso kune Slim LED - chii? Izvi zvinoshandiswa kutengeswa kweTV nehuwandu hwehutano hwemuviri ndeye 22.3 mm. Kazhinji mitambo yakadaro inoratidzika isina ruzivo rwakajairika rwakapoteredza chiyero, kunyange zvazvo chiri chokwadi chiri pasi pechigadziko cheganda.
Kubatsira kukuru kweTV maTV kungadanwa uye kuvandudzwa kwehuwandu hwemifananidzo. Kuburikidza nekushandiswa kwei
Iko kukonzera kukuru kweVVV TV ndeyayo yakadhura muhuwandu hwevhevhizheni nedzimwe mhando dzekuvhenekera. Zvisinei, inofungidzirwa kuti sezvo shanduro yekuvandudza inovandudza, kubudiswa kwemaTV ne LED rekugadzirisa zvinotora chimiro chemahombe, uye naizvozvo mutengo uchaterera zvishoma nezvishoma.
