Momwe mungayesere diagonal ya TV ndi momwe mungasankhire chipinda

TV diagonal – ndi chiyani, momwe mungasankhire ndi kuyeza mu mainchesi ndi masentimita. Pogula TV, amafuna kusankha imodzi yomwe imapereka mwayi wowonera bwino kwambiri. Choyamba, amaganizira za khalidwe la chizindikiro cha televizioni chomwe chikubwera, kuwonetsera kwa mitundu yosiyanasiyana ndi mithunzi pawindo, chiwerengero cha ma pixel omwe amagwiritsidwa ntchito komanso teknoloji yopanga nsalu. Makhalidwewa ndi ofunika, koma muyenera kumvetsetsa kuti ndi diagonal yosankhidwa molakwika, kuyang’ana sikungakhale kosavuta, komanso kumapangitsanso kuwonjezereka kwa maso.
Kuti muwonetsetse kuwonera bwino, ndikofunikira kuganizira osati kukula kwa chinsalu, komanso miyeso ndi mawonekedwe a chipinda chomwe TV imayikidwa. Mtengo wokulirapo umapangitsa chithunzicho kukhala chatsatanetsatane, ndi tsatanetsatane wokopa chidwi poyamba, ndipo kuti muwone chithunzi chonse, muyenera kupsinjika. Mukayang’ana pazenera laling’ono kwambiri, muyenera kuyang’ana nthawi zonse, zomwe zingasokoneze kufalitsa komweko ndikupanga vuto lamaso. Anthu ena amaganiza kuti sikirini yaikulu ikuwoneka yolemekezeka, koma powonera pafupi kapena m’chipinda chaching’ono, TV yaing’ono ingakhale yabwino kwambiri. Choncho, kudziwa diagonal ankafuna ndi mfundo yofunika posankha TV.

Momwe mungayesere diagonal ya TV mu centimita ndi mainchesi

Monga mukudziwira, chophimba cha TV chili ndi mawonekedwe amakona anayi. Kuti muwonetse miyeso yake, mutha kufotokoza kutalika ndi m’lifupi kapena kupereka kukula kwa diagonal. Njira yomaliza ndiyo njira yotchuka kwambiri yofotokozera mtengo wake. M’mayiko osiyanasiyana padziko lapansi, miyeso yoyezera kutalika imatha kukhala yosiyana. Mwachitsanzo, m’mayiko ambiri a ku Ulaya ndi chizolowezi kugwiritsa ntchito njira yoyezera SI, pomwe gawo lokhazikika ndi mita kapena zotumphukira zake (kuphatikiza centimita). Ku United Kingdom ndi ku United States, kugwiritsa ntchito mainchesi poyeza utali kwafala kwambiri. Mwachizoloŵezi, ndi m’mayunitsi awa pomwe mawonekedwe a diagonal amayesedwa.

1 inchi ndi 2.54 centimita. Chifukwa chake, 1 centimeter ndi mainchesi 0.3937. Pogwiritsa ntchito ziwerengerozi, mutha kuyimira zikhalidwe zomwe zafotokozedwa mu mainchesi mu centimita kapena kutembenuzanso. Mwachitsanzo, ngati kutalika kwa diagonal ndi mainchesi 40, ndiye kuti mutembenuzire ku centimita, nambala iyi iyenera kuchulukitsidwa ndi 2.54. Zotsatira zake, mtengo wofunidwa udzakhala 101.6 centimita.

Makanema oyambilira adagwiritsa ntchito gawo la 1: 1. Ndi chitukuko chaukadaulo komanso kubwera kwa umisiri watsopano wopanga ma skrini, 5:4, 4:3, komanso 16:9 idayamba kugwiritsidwa ntchito. Tsopano otchuka kwambiri ndi 16:9 ndi 21:9.

Momwe mungayesere kukula kwa diagonal molondola

Kuti mudziwe kukula kwa diagonal, ndikofunikira kuyeza kutalika kwa imodzi mwa ma diagonal awiri awonetsero, mwachitsanzo, yomwe imachokera kumunsi kumanzere kupita kumtunda kumanja. Ngati kutalika kwatsimikiziridwa mu masentimita, ndiye kuti mtengowo uyenera kugawidwa ndi 2.54. Poyerekeza ndi deta ya wopanga, ndikofunikira kufotokozera momwe miyeso yotere idapangidwira. Tiyenera kukumbukira kuti nthawi zina sitikulankhula za chinsalu, koma kukula kwa diagonal ya mlanduwo. Zikatero, poyerekezera, muyenera kuwongolera koyenera.

Momwe mungasankhire diagonal ya TV yazipinda zosiyanasiyana, madera, mtunda wa TV ndikuganiziranso zina

Kufunika kosankha kukula koyenera kwa diagonal ndichifukwa chazifukwa izi:

1. Miyezo yoyenera ya TV ipangitsa kuti pulogalamuyo iwoneke bwino kwa zaka zambiri.
2. Ubwino wapamwamba wa chithunzi chotsatira umatheka pamtunda wina, womwe udzakhala wabwino kwambiri. Ngati muyang’anitsitsa, ndiye kuti tsatanetsatane wa chithunzicho akhoza kuwonekera kwambiri, ngati muyang’ana mopitirira, zidzakhala zovuta kuti muzindikire kanemayo.
3. Kuwonera mapulogalamu a pa TV nthawi zonse kumapanga katundu wochuluka m’maso, zomwe pamapeto pake zingayambitse kuwonongeka kwa maso. Kusankha kolondola kwa mtunda wofika pazenera.
4. Zikawonedwa mu mawonekedwe apamwamba, pakhoza kukhala malingaliro aumisiri omwe ali okhudzana ndi kukula kwa diagonal. Mwachitsanzo, pa 3D iyenera kukhala mainchesi 49. Mukamagwiritsa ntchito 4K, mudzafunika kale chophimba chofanana ndi 50.

Chifukwa cha kafukufukuyu, malingaliro aperekedwa okhudza kusankha mtunda kuti muwone bwino. Maulendo ochepera komanso opitilira apo akuwonetsedwa apa. Malangizowa akuwonetsedwa pachithunzi chotsatirachi. Tabulo lakutali:
Kaŵirikaŵiri munthu amadziŵa m’chipinda chimene adzaikire TV. Miyezo yake imachepetsa mtunda womwe mawayilesi amakanema amatha kuwonera. Ayenera kusankha diagonal yomwe ikugwirizana ndi zomwe zilipo. Pachifukwa ichi, kusankha mtengo wovomerezeka kwambiri kukulolani kuti mupeze mavidiyo apamwamba kwambiri. Nthawi zina njira yapadera imagwiritsidwa ntchito yomwe imatsimikizira mgwirizano pakati pa kukula kwa diagonal ndi mtunda umene kufalikira kumawonekera. Kuti mudziwe kuchuluka kwa mawonedwe mmenemo, muyenera kuchulukitsa diagonal ndi 3 kapena 4. Chinthu china cholepheretsa chisankho ndicho kuthekera kwachuma kwa wogula. Choncho, pogula, nthawi zina zimakhala zopindulitsa kwambiri kugula chinsalu chocheperako masentimita angapo, koma nthawi yomweyo chili m’gulu lamtengo wapatali. Posankha, m’pofunika kuganizira ubwino wa chithunzi chotsatira. Ngati ili pamwamba, ndiye kuti mutha kuyiwona ngakhale mutagwiritsa ntchito mtunda wapafupi. Makanema omwe amapereka mawonekedwe a 720p ndiofala. Pamenepa, poyang’ana pa diagonal ya mainchesi 32 pafupi ndi mamita awiri, maonekedwe a zenera amawonekera kwambiri. Ngati musankha mtunda wokulirapo, chithunzicho chidzakhala chokongola kwambiri. Mutha kugwiritsa ntchito tchati chotsatirachi kuti musankhe mtunda womwe mukufuna.
Ndikofunikira kuganizira zaukadaulo molingana ndi zomwe chiwonetserochi chidapangidwa. Mukamagwiritsa ntchito LED kapena OLED, chinsalucho chimatsitsimutsidwa pafupipafupi kwambiri, kupangitsa kuwonera momasuka kuchokera kutali. Zithunzi zapamwamba kwambiri komanso kutulutsa mitundu zimalola wowonera kuti aziwoneka momasuka kuchokera pafupifupi patali kulikonse. Zowonetsera zochokera paukadaulo wa HDR zimapereka chithunzithunzi chabwino chowala, kutsimikizira mitundu yachilengedwe kwambiri. Mukamagwiritsa ntchito ma TV oterowo, ubale pakati pa kutalika kwa diagonal ndi mtunda wowonera umakhala wosakhazikika. Posankha chophimba chomwe chikufunika, munthu ayenera kudziwa cholinga chogulira. Ngati pakufunika kuwonera pamodzi, ndi bwino kusankha kukula kwakukulu. Mukagula, mwachitsanzo, chipangizo cha kukhitchini, TV yokhala ndi diagonal yaying’ono ingabwere. Posankha m’sitolo, ndizomveka kuima pamtunda womwewo womwe nyumbayo idzawonedwe ndikumverera Kodi chitsanzo chimenechi ndi choyenera bwanji? Momwe mungasankhire diagonal yoyenera ya TV: https://youtu.be/eDkmFwW5Wvk Nthawi zina, posankha, mutha kutsatira malamulo awa:

1. M’chipinda chaching’ono, chophimba chokhala ndi diagonal chomwe sichidutsa mainchesi 17 ndichoyenera.
2. M’chipinda chapafupifupi 18 sq. mamita ayenera kugwiritsa ntchito zipangizo zomwe zili ndi diagonal yosapitirira mainchesi 37.
3. M’zipinda zazikulu (ngati malowa ndi opitilira 20 masikweya mita), zowonetsera zomwe zimakwanira mainchesi 40 kapena kupitilira apo ndizoyenera.

Ndizomveka kupanga chisankho cholondola poganizira za kuwulutsa kwapawayilesi. Chipangizo chogulidwa chidzakhala chinthu chofunika kwambiri pakupanga chipinda. Zimafunika kusankha imodzi yomwe ingagwirizane ndi mapangidwe omwe alipo. Ndi chisankho cholakwika, zotsatira zosasangalatsa zitha kuchitika. Zitha kukhala ndi kuwonongeka kwa maso, kuyanika kwa mucous nembanemba wa diso, kupsinjika kwa minofu pogwiritsa ntchito malo osokonekera. Nthawi zina olakwika bungwe kuonera kumabweretsa mapangidwe mutu. Kukula kwazenera kosankhidwa bwino kudzapereka chitonthozo kwa zaka zambiri zogwiritsidwa ntchito. Kuti mupeze malo oyenera pazenera, ndikofunikira osati kusankha mtunda woyenera, komanso kukhazikitsa kutalika kwake. Malo abwino kwambiri ndi pamene pakati ali pa mlingo wa maso a omvera. Mkhalidwewu ndi wololedwa
