Kushanduka kweTekinoroji yekugadzira Terevhizheni yeFlat Screen
Terevhizheni yava chikamu chakakosha chehupenyu hwemazuva ano, ichipa varaidzo, ruzivo, nedzidzo nenzira inonakidza. Kubva pakagadzirwa terevhizheni yekutanga naJohn Logie Baird muma1920, tekinoroji yeterevhizheni yafambira mberi nekukurumidza. Chimwe chekushanduka-shanduka kukuru munhoroondo yeterevhizheni kwaive kuchinja kubva pakuratidzira kwe cathode ray tube (CRT) kuenda kukuratidzira kwe flat-panel. Chinyorwa chino chichaongorora kushanduka kwetekinoroji yekugadzira terevhizheni ye flat-panel, kuona zvinhu zvitsva zvakakosha, uye kuratidza ramangwana rayo.
Kugadzirwa kweCRT Television: Nguva Yekutanga
Materevhizheni ekutanga akagadzirwa nevanhu vakawanda aive materevhizheni eCRT (Crystal Resonance Resonance). Materevhizheni aya aishandisa machubhu evacuum kuratidza maerekitironi pachidzitiro chakafukidzwa nephosphor, icho chakazoburitsa mufananidzo. Kunyangwe materevhizheni eCRT akachinja varaidzo yepamba, aive nemiganhu yakawanda, kusanganisira kukura kwawo kukuru uye huremu husingashande, pamwe nekushandisa kwawo simba rakawanda.
Kuchinja Kuenda KumaFlat Screens: LCD nePlasma
Kuratidzwa kweMakristaro eLiquid (LCD)
Mukupera kwema1990 nekutanga kwema2000, materevhizheni e flat-panel akatanga kubuda, zvichichinja mamiriro etekinoroji yeterevhizheni. Liquid Crystal Display (LCD) ndiyo tekinoroji yakatungamira shanduko iyi. Materevhizheni eLCD anoshanda nekushandisa makristaro emvura akaiswa pakati pemagirazi maviri kana mapurasitiki. Kana magetsi emagetsi ashandiswa, makristaro aya anochinja maonero awo kuti adzore kuti chiedza chinobva kuchiedza chemashure chinopfuura sei nepakati pawo, zvichigadzira mufananidzo.
Chinhu chikuru chine materevhizheni eLCD ndechekuti matete awo, izvo zvinoita kuti magadzirirwo awo ave akanaka uye anoyevedza. Uyezve, materevhizheni eLCD akareruka uye anoshandisa simba shoma pane materevhizheni eCRT. Dambudziko guru pakutanga raive makona mashoma ekuona uye kubereka mavara asina kunaka, kunyangwe izvi zvakavandudzwa zvikuru nekufamba kwenguva nekuvandudzwa kwetekinoroji dzepaneru dzeIPS (In-Plane Switching) nedzimwewo.
Panera rePlasma Display (PDP)
Pamwe chete nemaLCD, tekinoroji yePlasma Display Panel (PDP) yakabudawo senzira yekuchinja materevhizheni ane maflat-panel. Materevhizheni ePlasma anoshandisa gasi rine ionized kugadzira maphoton akareruka kana magetsi ashandiswa. Iyi tekinoroji inobvumira mavara akapfuma uye maangle ekuona akafara kupfuura maLCD.
Zvisinei, materevhizheni eplasma ane zvipingamupinyi zvakawanda, zvinosanganisira kushandiswa kwesimba rakawanda uye mukana wekupisa, uko mifananidzo isingachinji inogona kusiya mimvuri inogara iripo pachiratidziro. Kunyangwe yakakurumbira zvikuru mumakore ekuma2000, kufambira mberi kwakawanda mutekinoroji yeLCD uye kubuda kweOLED (Organic Light Emitting Diode) zvakaita kuti kufarirwa kwematerevhizheni eplasma kudzikire.
OLED: Chinjo Itsva muFlat Screens
OLED tekinoroji itsva yekuratidza mifananidzo ine mapaneru akatsetseka uye yave ichirumbidzwa sechinjo huru mukugadzirwa kwemifananidzo uye terevhizheni. Kusiyana nemaLCD, ayo anoda mwenje wekumashure, pixel yega yega iri paOLED skrini inogadzira chiedza chayo kana magetsi ashandiswa. Izvi zvinobvumira maOLED kugadzira matema akadzika, musiyano wakanyanya, uye ma angle ekuona akafara.
Matelevisheni eOLED ane mukana wekuva matete zvakanyanya, anochinjika, uye akareruka. Anopawo nguva yekupindura nekukurumidza uye kushanda nesimba kwakanyanya kana tichienzanisa neLCD neplasma technology.
Maitiro eQLED neRemangwana
Quantum Dot Light Emitting Diode (QLED) tekinoroji yekuratidza madhatabheti inoshandisa quantum dot nanoparticles inovhenekerwa ne LED backlight. Izvi zvinobvumira QLED kugadzira mavara akajeka uye ruvara rwakakura kupfuura maLCD akajairwa. Materevhizheni eQLED ane zvakanakira mukupenya, kuramba kupisa, uye kunaka kwemifananidzo mumamiriro akasiyana-siyana emwenje.
Mumakore mashoma apfuura, matekinoroji akaita seMicroLED akabuda, achibatanidza zvakanakira LED nekutetepa uye kushanda zvakanaka kweOLED. MicroLED inopa mukana wekugadzira masikirini makuru pasina kukanganisa kunaka kwemufananidzo, pamwe nekushandisa simba zviri nani uye hupenyu hurefu.
Kufambira Mberi Mukugadziriswa Kwechidzitiro
Kuwedzera kune tekinoroji yemapaneru, kushanduka kwe resolution yechidzitiro kwavewo chinhu chakakosha pakufambira mberi kweterevhizheni ye flat-panel. Kubva pa standard resolution (SD) kusvika ku High Definition (HD), Full HD (FHD), 4K Ultra HD, uye ikozvino 8K, kufambira mberi kwe resolution yechidzitiro kunopa ruzivo rwakadzama uye runonyudza rwekuona.
Kubatana uye Smart TV
Pamusoro pekuvandudzwa kwemhando yemifananidzo, materevhizheni emazuva ano ane flat-screen anewo zvinhu zvakasiyana-siyana zvekubatanidza uye mashandiro esmart TV. Kubatanidza Wi-Fi, Bluetooth, uye system yekushandisa yakavakirwa paAndroid kana imwe inobvumira terevhizheni kubatana neinternet, kuwana maapplication ekuteerera, uye kutodzora imba yakangwara.
Vatengi uye Zvakatipoteredza
Tekinoroji yeterevhizheni ine mapaneru efurati haingobatsiri chete vatengi maererano nemhando yemifananidzo uye maficha ayo, asiwo inopa zvakanakira nharaunda. Materevhizheni matsva ane mapaneru efurati anowanzo shandisa simba zvakanyanya kupfuura materevhizheni eCRT neplasma. Uyezve, kufambira mberi mukugadzirwa kwetekinoroji nezvinhu zvakaita kuti materevhizheni ave neushamwari kune nharaunda uye zvive nyore kuadzokorodza.
Matambudziko uye Remangwana
Pasinei nekufambira mberi kukuru, indasitiri yeterevhizheni ine mapaneru epamusoro ichiri kutarisana nematambudziko akati wandei. Semuenzaniso, mitengo yekugadzira OLED neMicroLED ichiri yakakwira, zvichikonzera mitengo yakakwira yevatengi. Kugadzira zvinhu zvinoshanda uye matekiniki ekugadzira asingadhuri kuchiri chinhu chakakosha.
Mune ramangwana, tinogona kutarisira zvimwe zvitsva zvakaita sezviratidziro zvinopetwa uye zvinoonekera, izvo zvichavhura mikana mitsva mukugadzira uye kushanda kweterevhizheni. Kufambira mberi mune zvehungwaru hwekugadzira kunogonawo kugonesa terevhizheni kupa ruzivo rwevaraidzo rwakagadzirirwa iwe pachako uye rwakagadzirirwa iwe.
Mhedziso
Kufambira mberi kwetekinoroji yekugadzira terevhizheni ine mapaneru akatsetseka kwakagadzira shanduko huru mumhando uye nyore kwevaraidzo yekumba. Kubva kuLCD neplasma kusvika kuOLED neQLED, hunyanzvi huri kuramba huchienderera mberi. Tekinoroji yega yega ine zvayakanakira nematambudziko ayo, asi zvese zvinobatsira pakuona zviri nani uye zvinonakidza. Nekufambira mberi kwetekinoroji, ramangwana reterevhizheni ine mapaneru rakataridzika zvakanaka, richivimbisa zvimwe zvinoshamisa uye kufambira mberi kucharamba kuchishamisa.
