Momwe mungayang’anire ma pixel akufa pa TV pogula komanso kunyumba

Momwe mungayang’anire ma pixel akufa pa TV – momwe mungadziwire pixel yakufa ndi nyali zopanda mawonekedwe mukagula m’sitolo ndi njira zoyesera ndikuyang’ana kunyumba. Zowonetsera pa TV ndizojambula zovuta kwambiri, zomwe nthawi zambiri zimasweka pa fakitale kapena m’sitolo. Chifukwa cha izi, ndikofunikira kudziwa za vuto lalikulu la matrices onse mu ma TV – ma pixel osweka. Nkhaniyi ifotokoza zomwe zili, momwe mungadziwire, komanso momwe mungakonzere nokha. Tiwonanso momwe tingayang’anire TV kuti igwiritsidwe ntchito pogula TV yatsopano kapena yogwiritsidwa ntchito komanso momwe mlandu wawaranti umagwirira ntchito. Osati nthawi zonse malfunctions ndi chophimba amaonedwa chifukwa ufulu kukonza sitolo.

Kodi pixel yakufa pa Smart TV ndi chiyani, imawoneka bwanji nthawi zonse

Chiwonetsero chilichonse chimawonetsa chithunzi pogwiritsa ntchito ma pixel – awa ndi ma LED omwe amawunikira ndi kuwala kwina. Chiwerengero chawo chachikulu chimapanga zotsatira za chithunzi chosuntha. Amagwira ntchito popanda wina ndi mzake ndipo amalamulidwa ndi wolamulira. Pixel iliyonse imakhala ndi ma pixel – awa ndi mababu a RGB amitundu yofiira, yobiriwira ndi yabuluu. Ngati muwonetsa mitundu itatuyi mosiyana, mutha kupeza mtundu uliwonse kuchokera ku sipekitiramu yowonekera kwa munthu. Ngati muyatsa mitundu yonse itatu, mumakhala woyera, ndipo ngati muzimitsa – wakuda. Motero chithunzicho chimapangidwa.
Ngati pixel yawonongeka, sichingalepheretse chipangizo chonsecho, koma imapanga kadontho kakuda pazenera pamalo amodzi. Nkhani zina zokhala ndi pixel zimatha kupangitsa kuti izingowala mumtundu umodzi kapena osazimitsa ngakhale chithunzicho chili chakuda. Chifukwa chake, mukawonera makanema, pamakhala vuto lamtundu nthawi ina, zikuwoneka motere:

Ndi mitundu yanji ya ma pixel akufa omwe ali pa TV

Pixel imatha kuchita mosayembekezereka pazifukwa zosiyanasiyana, kuyambira pakuchepetsa mtengo mpaka kuwonongeka kwakuthupi panthawi yotumiza. Monga choncho, ma pixel sangathe kusweka ngakhale patatha zaka zambiri akugwira ntchito. Pali mitundu itatu ikuluikulu ya ma pixel akufa, ndiyo:

1. Malo oyera (dzina lodziwika kwambiri ndi pixel yotentha). Pixel yoteroyo imakhala ndi zovuta ndi wowongolera, samamvetsetsa malamulo operekera magetsi ndipo imapanga kuchuluka kwamakono. Chifukwa cha izi, pixel imayaka kwambiri, ndipo izi zimapanga chithunzi choyera. Pixel yoteroyo nthawi zonse imawala moyera.
2. Dontho lakuda . Iyi ndi pixel yakufa, imatha kuwotcha kapena kusalandira malamulo kuchokera kwa wowongolera ndipo imakhala yozimitsa nthawi zonse.
3. Dothi lamtundu (dzina lachiwiri ndi pixel yokhazikika). Izi zimapangidwa pamene imodzi mwa ma subpixels ake (babu lowala lofiira, lobiriwira kapena labuluu) likulephera. Pachifukwa ichi, ma pixel sangathe kuphatikiza mitundu ya RGB nthawi zonse, chifukwa chake nthawi zonse imawunikira mumtundu umodzi, kapena katchulidwe kake kamasinthidwa kukhala imodzi mwa mapepala (mwachitsanzo, payenera kukhala kuwala kobiriwira, koma mfundo ndi yachikasu). Zowonongeka zamtunduwu zitha kukonzedwa nokha.

Momwe mungadziwire pixel yosweka pa TV yokhala ndi matrices osiyanasiyana

Ndikoyenera kulingalira kuti pali mitundu iwiri ikuluikulu ya matrices, omwe ndi mawonedwe a LCD ndi OLED. Pakatikati pawo, amagwira ntchito mofananamo, koma ma OLED akadali okonda kutenthedwa ndi pixel, yomwe ndi pamene chithunzithunzi chimakhalabe pazenera ngati chikudyetsedwa ku TV kwa nthawi yayitali. Chilema choterocho chimaonekera mwa kusanjika chithunzi chimodzi pa china. Zowonetsera za LCD sizikhala ndi izi, choncho zimakhala zolimba. Pali mitundu yambiri ya matrices a LCD (matrices amadzimadzi a crystal), koma mitundu yawo simakhudza momwe ma pixel akufa amapezera, kutsimikiziridwa ndi kukonzedwa. Ngati TV ili ndi matrix a IPS, QLED kapena Nano Cell, ndiye kuti iyi ndi matrix a LCD.

Zofunika! Ena opanga kapena ogulitsa nthawi zina amalemba mtundu wa skrini ya LED. Monga njira yowunikiranso, kwenikweni, awa ndi matrices wamba a IPS.

Kupitilira munkhaniyi, tisanthula momwe tingadziwire ndi kukonza ma pixel osweka pa TV kunyumba kapena kubweza pansi pa chitsimikizo.

Ndi ma pixel angati akufa omwe amaloledwa pamitundu yosiyanasiyana ya matrix

Ngati ma pixel osweka akuwonekera pa TV, mutha kubweza ku sitolo pansi pa chitsimikizo (zowona, ngati sichinathebe). Koma si zolakwika zonse zokhala ndi matrices zomwe zimatengedwa ngati zitsimikiziro; nthawi zina, kukonzanso kungakanidwe. Chifukwa cha zovuta kupanga zowonetsera, owongolera abwera ndi muyezo womwe umayang’anira zofooka zina zopanga ndikulola kuti ma pixel ochepera akufa aziwoneka ngati abwinobwino komanso osagwirizana ndi chitsimikizo. Monga tanenera kale, pali mitundu itatu ya ma pixel akufa. Aliyense wa iwo amalamulidwa mosiyana. Ma TV onse amagawidwa m’magulu anayi aukadaulo, kalasi yapamwamba, matrix abwinoko komanso zofunikira zake zimakhala zolimba. Nawa magawo omwe matrices amagawidwa mu ma TV amakono:

1. Kalasi yoyamba – sipayenera kukhala ma pixel akufa konse, kapena chiwerengero chawo chochepa, chiwerengero chachikulu chimatengedwa kuti ndi cholakwika ndipo chimaphimbidwa ndi chitsimikizo. Zimachitika mu zitsanzo zodula kwambiri.
2. Kalasi yachiwiri ndi matrices apamwamba kwambiri, omwe ndizabwinobwino kukhala ndi ma pixel akufa khumi ndi awiri. Zofanana ndi zida zodula.
3. Kalasi yachitatu ndi mtundu wotchuka kwambiri wa kalasi, womwe umakhala ndi mitundu yambiri ya bajeti. Ma pixel ang’onoang’ono akufa amaloledwa, omwe sawoneka m’moyo weniweni.
4. Kalasi yachinayi ndi matrices otsika mtengo okhala ndi ma pixel owoneka akufa. Ma pixel 262 osagwira ntchito pa miliyoni amaloledwa. Siziwoneka kawirikawiri.

Pali tebulo lapadera lomwe likuwonetsa kuchuluka kwa ma pixel omwe atha kufa pamagulu osiyanasiyana a zida:

Kuti mudziwe kuchuluka kwa ma pixel onse pa matrix, muyenera kuchulukitsa chiwonetsero chazithunzi molunjika ndi chopingasa. Zimalembedwa ngati zikhalidwe ziwiri, zomwe zimasiyanitsidwa ndi nyenyezi kapena chizindikiro “X”. Mwachitsanzo, 1280×720, 1920*1080 ndi zina zotero. Pali zisankho zazikulu zitatu pa TV, zomwe ndi:

1. HD – kusamvana kwakukulu, komwe ndi 1280 ndi 720 pixels, zomwe zikutanthauza kuti ma TV awa ali ndi ma pixel 912,600.
2. FullHD ndiye mtundu wotchuka kwambiri, wokhala ndi madontho opingasa a 1920 ndi madontho 1080 ofukula. TV iyi ili ndi ma pixel 2,073,600.
3. 4K ndiye TV yapamwamba kwambiri yokhala ndi malingaliro apamwamba kwambiri pakadali pano. Ili ndi madontho opingasa 3840 ndi madontho 2160 ofukula. Mukachulukitsa mtengo, mutha kudziwa kuti pali ma pixel 8.3 miliyoni. Ma TV otsika mtengo sakhala ndi muyezo uwu, choncho nthawi zambiri ma TV ndi a kalasi yachiwiri ndi pamwamba.

Momwe mungayang’anire TV kuti muwone ma pixel akufa kunyumba komanso mayeso mukagula m’sitolo

Zitha kukhala zovuta kuyang’ana ma pixel akufa m’sitolo chifukwa cha zoletsa zamabizinesi. Wogulitsa sangalole kugwiritsa ntchito laputopu kapena zida zina, koma adzadzipereka kuti ayang’ane chiwonetserochi kuti awonjezere ndalama. Izi zimathetsedwa pogwiritsa ntchito njira yoyamba. Kunyumba, ndi kosavuta kugwiritsa ntchito njira yachiwiri, koma yoyamba idzagwira ntchito.

Ndi flash drive

Kuti muwone mwachangu ma pixel akufa, mutha kugwiritsa ntchito flash drive yokonzekeratu. Ndikokwanira kuchita zotsatirazi kuti muwone zowonetsera zilizonse za pixel zakufa kapena kuwotcha kwa TV:

1. Konzani flash drive iliyonse kapena gwiritsani ntchito foni yamakono yokhala ndi chingwe cha USB.
2. Kwezani zithunzi zisanu zamtundu umodzi muchikumbutso cha chipangizocho, pomwe padzakhala mitundu yoyera, yakuda, yofiira, yobiriwira ndi yabuluu.
3. M’sitolo, gwirizanitsani galimoto kapena foni ku TV pogwiritsa ntchito cholumikizira cha USB kumbuyo kwake.
4. Pa TV yokha, tsegulani mndandanda wa ntchito ndikupita kwa woyang’anira fayilo.
5. Pezani chida cholumikizidwa ndikutsegula zithunzi zonse m’makumbukidwe ake chimodzi ndi chimodzi.
6. Pofufuza chithunzicho, chiyenera kukhala cholimba komanso chopanda chilema chilichonse. Makamaka m’pofunika kumvetsera mtundu wakuda, chifukwa kuwala kumawonekera bwino pa izo.

Zofunika! Muyenera kutsitsa zithunzi zapamwamba zokhala ndi mawonekedwe a kanema wawayilesi. Nthawi zambiri, mtengo uwu ndi 16 ndi 9.

Mutha kutsitsa ndikugwiritsa ntchito zithunzi zomwe zili pansipa kuti muwone TV iliyonse ngati ma pixel akufa. Chachikulu ndichakuti chithunzicho chimakwirira matrix onse ndikupereka kuwala kwanthawi zonse popanda zosokoneza. [zigawo zanyumba = “5” ids = “9936,9937,9938,9939,9940”]

Kuyang’ana masanjidwe a ma pixel osweka pogwiritsa ntchito pulogalamu ya chipani chachitatu

Pa ma TV omwe ali ndi makina ogwiritsira ntchito a Android TV, mutha kukhazikitsa pulogalamu ina yowonera mtundu wa matrix kuchokera kusitolo yovomerezeka ya Play Market. Ndikokwanira kulemba “Kuwona matrix” pofufuza ndipo kukupatsani zotsatira zambiri. Kwa machitidwe ena opangira ma TV, kapena ngati alibe Smart TV, muyenera kugwiritsa ntchito kompyuta ya Windows kapena laputopu. Muyenera kulumikiza zida ziwiri pogwiritsa ntchito chingwe cha HDMI, ndi pa PC, chitani izi:

• Tsitsani pulogalamu yaulere ya Eizo Test Monitor kuchokera pa intaneti. Sichifuna unsembe ndi bolodi iliyonse, izo zimagwira ntchito mwamsanga pambuyo unpacking archive.
• Tsegulani chikwatu kuchokera pankhokwe ndikuyendetsa fayilo ya exe mmenemo.
• Yang’anani mabokosi kuti muwone zofunikira ndikuyesa mayeso pogwiritsa ntchito batani lomwe lili pakona yakumanja.
• Zithunzi zosiyana zidzawonekera pa TV motsatira, zomwe zidzakuthandizani kuzindikira zolakwika mosavuta.

Momwe mungakonzere ma pixel akufa amtundu

Ngati ma pixel akufa achikuda adawonedwa pa chipangizocho (chomwe chimawotcha mtundu umodzi kapena kuwonetsa molakwika), ndizotheka kukonza kunyumba, chifukwa chake muyenera kutsatira malangizo awa:

1. Tsegulani chithunzi chilichonse chomwe sichikugwirizana ndi pixel iyi.
2. Ikanini pang’ono ndi malo ofewa, monga ndodo ya khutu, ndipo dikirani kwa mphindi 20.
3. Ngati zotsatira sizitha, mukhoza kubwereza ndondomekoyi kachiwiri.

Zofunika! Osapitilira izi, apo ayi zosintha sizingangokonza pixel, komanso kuwononga oyandikana nawo. Ndi bwino kugwiritsa ntchito ntchito za mbuye.

Momwe mungayang’anire TV ya ma pixel akufa ndi kuwala – cheke chathunthu ndi kuyesa kwa Smart TV m’sitolo mutagula: https://youtu.be/vOinxIaNwXA

Momwe mungayang’anire TV yanu kuti ipeze kuwala

Backlight ndikugawa kosagwirizana kwa nyali zakumbuyo mu LCD. Ma pixel onse sadziwunikira okha (izi ndizomwe matrix a OLED amachita), kuti muwone chithunzicho, amayika chinthu chowonjezera chazithunzi pansi pa ma pixel. Simawotcha bwino mofanana, kotero kuti mbali zina za chithunzicho zikhoza kuwala kwambiri kuposa zina. Zindikirani! Matrices okhala ndi mtundu wowunikira kumbuyo kwa LED amagwiritsa ntchito nyali kumanzere ndi kumanja kwa chida cha chipangizocho. Izi zimapanga zowoneka bwino zachilengedwe pamakona. Paziwonetsero zoterezi, izi ndizokhazikika, chinthu chachikulu ndikuti palibe madontho akuda pamakoma, monga momwe tawonetsera mu chitsanzo pansipa:
Kuti mudziwe kuwala kwambuyo, ndikwanira kutsegula chithunzi chakuda pa TV, pamene chinsalu chikuwonekera. Mutha kugwiritsa ntchito zokonda zakuda, kuyatsa kanema wokhala ndi zithunzi zakuda, kapena kugwiritsa ntchito mtundu wina uliwonse. Ngati mawanga oyera oyera akuwoneka m’malo akuda a chithunzicho, ndiye kuti TV yotereyi ili ndi zolakwika zowunikira matrix, monga momwe ziliri m’chitsanzo chomwe chili pansipa:
Pogwiritsa ntchito malangizowa, mutha kuyang’ana pa TV mosavuta kuti muwone momwe chiwonetserochi chilili. kugula. Simuyenera kuchita mantha kwambiri ndi ma pixel akufa, chifukwa gawo laling’ono la iwo ndilokhazikika ngakhale paukadaulo watsopano. Chachikulu ndichakuti ma pixel otere sapanga chisokonezo powonera TV. Zolakwika zotere sizitha kupita patsogolo ngati simugwetsa kapena kumenya nkhani ya TV.
