- Ukushintsha kusuka ezinhlelweni zokuqala zemishini neze-elekthronikhi kuya enkathini yedijithali kanye ne-Smart TV.
- Ukuhlaziywa okuningiliziwe kwezikrini ze-LCD, LED, Plasma kanye nomkhawulo wakamuva wamaphaneli e-OLED kanye ne-MicroLED.
- Izinyathelo ezibalulekile kwikhwalithi yesithombe, kusukela ekufikeni kombala kuya ekuxazululweni kwe-UHD, ubuchwepheshe be-4K kanye ne-quantum dot.
Kuyamangalisa ukucabanga ukuthi idivayisi ebusa igumbi lokuphumula manje, njengoba iyisizinda sezokuzijabulisa nobuchwepheshe, isuselwe ku ngasekupheleni kwekhulu leshumi nesishiyagalolunyeKwakungeyona into eyodwa esunguliwe, kodwa kwakuyiqoqo lezinto ezintsha ezahlukahlukene ezahlangana ukuze kudalwe idivayisi esivumela ukuthi sizithuthele kwamanye amazwe ngaphandle kokushiya isofa.
Kusukela kulezo zikrini zokuqala eziyisisekelo kuya kumaphaneli anamuhla amancane kakhulu, imboni ithathe igxathu elikhulu. Intuthuko ngayinye yobuchwepheshe ayibanga nje yinto efunwa unjiniyela, kodwa ihlose ukwenza isipiliyoni sokubuka kube okujulile kakhulu, okucacile futhi, kalula, okujabulisayo kumsebenzisi wokugcina.
Izisekelo: kusukela kumakhenikha kuya kuma-elekthronikhi
Ukuze siqonde ukuthi sikuphi, kufanele sibheke emuva, ikakhulukazi ngo-1884, lapho imibono yokuqala yasungulwa khona. Nakuba kwathatha iminyaka ngaphambi kokuba ithengiswe, ekuqaleni yayingavamile kangangokuthi abantu abangaba ngu-50 kuphela Babenayo eyodwa. Isigaba sokuqala kwakuyithelevishini yemishini, ebizwa nangokuthi ithelevishini yokuskena yemishini (CRT), eyayisebenzisa amaphrojektha e-electromechanical. Isenzakalo esibalulekile senzeka ngoMashi 25, 1925, lapho iScotsman UJohn Logie Baird Yabonisa izithombe zomphakathi ezinyakazayo okokuqala ngqa.
Kodwa-ke, izinhlelo zemishini zaziyinkimbinkimbi kakhulu futhi ikhwalithi yayingadingeki. Ngakho-ke, kwazalwa ithelevishini kagesi, eyaboniswa eSan Francisco ngoSepthemba 1927 ngenxa yomsebenzi ka UPhilo Taylor FarnsworthLolu hlelo lusebenzise amasignali kagesi ukuveza izithombe nemisindo ngamagagasi omsakazo noma ama-microwave, lubeka isisekelo salokho ebesingase sikwazi amashumi eminyaka.
Ukuguquka kombala kanye nokwenyuka kwedijithali
Nakuba amalungelo obunikazi aseJalimane ayekhona kusukela ngo-1904 futhi uVladimir K. Zworykin wenza iziphakamiso zethelevishini enemibala ngo-1925, impumelelo yangempela yafika kamuva. Ama-RCA Laboratories athuthukisa uhlelo lokuqala lukagesi olusebenza kahle phakathi kuka-1946 no-1950, okwenza ukusakazwa kuqale ngoDisemba 1953. izikhangiso zombalakushintsha njalo ubuhle bethelevishini.
Ngokuhamba kwesikhathi, ikhebula lafika ngawo-1970 kanye nama-VCR ngawo-1980. Kodwa ushintsho olukhulu kwaba ithelevishini yedijithaliLolu hlelo luvumele ukudluliswa komsindo nevidiyo ngamanethiwekhi asemhlabeni, isathelayithi, noma ikhebula elinekhwalithi ephezulu kakhulu. Ekupheleni kweminyaka yama-2000, amazwe amaningi athuthukile ayesevele edlulele ngale kwezimpawu ze-analog futhi amukele indinganiso yedijithali.
Ukuhlaziywa kobuchwepheshe bokubonisa
Eminyakeni edlule, ubuchwepheshe obuhlukene buye baba khona ukuze kukhiqizwe isithombe, ngasinye sinezinzuzo kanye nokungalungi kwaso:
- Izikrini ze-LCD: Zisebenza kusetshenziswa izendlalelo ezintathu zokukhanyisa kwe-liquid crystal backlighting (obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka). Zisebenzisa amandla aphansi kakhulu futhi ziyonga, yize zisebenza kahle. umehluko uphakathi nendawo uma kuqhathaniswa nezinye izinketho.
- Izikrini zePlasma: Babeyizingqalabutho zekhwalithi. Bakha isithombe besebenzisa amachashazi e-phosphor akhipha ukukhanya kwawo, befeza abamnyama abajulile kanye nokugqama okuphezulu kakhuluyize zidla amandla amaningi futhi zingcolisa kakhulu.
- Ubuchwepheshe be-LED-LCD: Kuyi-hybrid esebenzisa ama-LED ukukhanyisa isikrini. Inikeza inhlanganisela elinganiselayo phakathi kokusetshenziswa kwamandla aphansi, isikhathi eside sokuphila kanye nekhwalithi ephezulu kakhulu yesithombe.
- Amaphaneli we-OLED: Lapha, iphikseli ngayinye iyisici sezinto eziphilayo esikhanyisa nge-electric impulse. Zinhle kakhulu, zivumela amajika emvelo futhi zinikeza umehluko omuhle kakhulu emakethe (isigidi esisodwa kuya kwesinye), yize isikhathi sazo sokuphila sifushane kuneso sama-LED.
Isikhathi sobuhlakani kanye nencazelo ephezulu
Ukufika kwama-Smart TV kwaguqula ithelevishini yaba yikhompyutha exhunyiwe. Ngenxa yokuhlanganiswa kwe I-inthanethi kanye ne-Web 2.0Manje sinezitolo zezinhlelo zokusebenza, ukuphequlula iwebhu, kanye nezinsizakalo zokusakaza bukhoma ezifana Ukusakaza bukhoma ihlanganisiwe. I-Samsung, isibonelo, yaba ngumsunguli wesitolo sokuqala sezinhlelo zokusebenza ze-TV kanye ne-Smart Hub ngo-2010.
Ngokuphathelene nesisombululo, sisuke ku-Full HD saya ku-UHD (Ultra High Definition) enamaphikseli ayizigidi ezingu-8, sabe sesiya ku- I-4K ne-SUHDIsingeniso se- amachashazi e-quantum Kuvumele ukufeza ivolumu yombala engu-100% kanye nokunemba okumangalisayo kokukhanya, okwenza izithombe zicishe zifane neqiniso.
Izinto ezintsha eziphazamisayo kanye nekusasa elibonakalayo
Umklamo nawo ushintshile. Sisuke emabhokisini amakhulu saya ezikrinini ezisicaba sabe sesiya amathelevishini agobile befuna ulwazi olujulile. Kuze kwadalwa nezikrini eziguquguqukayo abasebenzisi abangazivumelanisa nazo ngendlela abayithandayo. Imikhiqizo efana ne-Samsung ihambele phambili nakakhulu nge- Imodi Ekhona, efihla ithelevishini ngemihlobiso yasekhaya, noma i-One Invisible Connection ukuze kuqedwe ukuxinana kwekhebula.
Ukubheka phambili, ubuchwepheshe I-MicroLED Ithembisa ukuguqula yonke into. Njengamamojula okubonisa azimele, avumela ukudalwa kwezikrini ezinkulu, njenge-"The Wall," ezigcina ikhwalithi emangalisayo kungakhathaliseki ukuthi zingakanani. Ngokufanayo, izinkampani ezifana ne-TCL ziqhuba lokhu Mini Mini, kusetshenziswa izinkulungwane zamaphikseli amancane ukulawula ukukhanya okunembile kanye nezigcawu zebhayisikobho.
Kusukela kulezo zinsimbi zokuqala zemishini zasekupheleni kwekhulu le-19 kuya kumaphaneli e-MicroLED ahlaba umxhwele kanye nokuhlanganiswa okugcwele nobuhlakani bokwenziwa, ithelevishini iye yavumelana nenkathi ngayinye. Lolu hambo luye lwaphawulwa umzabalazo oqhubekayo wokufeza imibala ecace kakhudlwanaImibala emnyama nemiklamo ehlanganiswe empilweni yethu yansuku zonke, iba yiwindi ledijithali elithandwayo lezigidi zabantu.
