Ndi mitundu yanji ya oyang'anira?

Kuwunika ndilo gawo lofunika kwambiri pa kompyuta iliyonse. Ndilo chipangizo chomwe kompyuta imalongosola zotsatira za ntchito yake kwa munthuyo. Ngati wogwiritsa ntchitoyo akupanga deta yapachiyambi ndi mbegu ndi kibokosi, ndiye kompyuta imalongosola zotsatira za mawerengedwe ake kupyolera mu chithunzi pazenera .
Mtundu woterewu. Mosiyana ndi zigawo zing'onozing'ono zamkati, chipangizo ichi sichitha kuzindikira, kotero aliyense ali ndi lingaliro lachidule. Ndimeyi tidzakwaniritsa chidziwitso cha chidziwitso, ndikuganizira mwatsatanetsatane mitundu yowonera.

Malinga ndi mtundu wa mawindo ogwiritsira ntchito, zipangizo zonse zoterezi zingagawidwe m'magulu awiri akuluakulu - zamakono zamakono (LCD, TFT, LCD) ndipo zachotsedwa pamtunda, electron mtanda (CRT). Nthawi zina mndandandawu umaphatikizidwa ndi mtundu wachitatu - mapepala a plasma, koma izi ndi zothetsera mavuto, omwe sangatchedwe misala. Potero, kuphunzira mitundu ya oyang'anitsitsa, ndi ochepa ku LCD ndi CRT.

Zoonadi, ambiri amakumbukira momwe TV imayang'ana "nyengo yamadzi yamadzi". Iwo anali zipangizo zazikulu kwambiri, chinsalu chake chomwe chinali kutali kwambiri. Ngakhale m'zaka zaposachedwapa nkhaniyi yasintha kwambiri. Amene anali ndi mwayi woyang'ana mkati mwa CRT casing ya TV, amadziwa kuti pafupifupi pafupifupi lonse bukuli anali wotenga chubu-ray, ndipo kukula kwa bolodi bolodi kawirikawiri kupitirira gawo la Album pepala. Kugwirizana pakati pa khungu ndi TV ndikulunjika: amagwiritsanso ntchito zomwezo. Inde, mkati mwa teknoloji yomweyo yopanga.

Poganizira mtundu wa oyang'anitsitsa, simungathenso kuchoka pambali yothetsera vutoli. Choncho, tiyeni tilembere ubwino wa oyang'anira CRT :

- Pafupifupi mtundu wonse wa magulu opangira mtundu, ngakhale chitsanzo cha bajeti kwambiri pambali imeneyi ndi mofulumira kwambiri kuposa LCD yopambana;

- Kusakhala ndi mawonekedwe oyang'ana - chithunzi pachiwonekera nthawi zonse chikuwoneka, mosasamala momwe ndondomeko ya masomphenya imagwera pa iyo;

- ma pixel osweka, mliri wa teknolojia yonse yamakina yamakina, sangakhalepo mu zitsanzo za CRT;

- palibe vuto pogwedeza chithunzi pamene mukuwonetsa zojambula zamphamvu.

Koma madzi a crystal mitundu ya oyang'anitsitsa akhoza kudzitama ndi zosiyana makhalidwe:

- Kutsika kwa mphamvu kuchokera pa intaneti, mtengo wamba ndi 40 W (kuyerekeza ndi 80 ndi zambiri CRT);

- Zing'onoting'ono zofanana ndi kulemera kwake, zomwe zikutanthauza kuti kuyika kachipangizo kotere pa khoma, palibe chifukwa chokwera choyimira cholimba;

- Zosavuta kuchepa m'maso: kuchepa kwa kayendedwe ka mawonekedwe a backlight ndi mazana a megahertz (osagwirizana ndi maonekedwe omwe apanga, chifukwa cha kupezeka kwa PWM malamulo, akadalipo);

- kumveka bwino kwa chithunzichi ndikumangokhalira kutembenuza miyendo nthawi imodzi, kuphatikizapo kusatheka kwa kupotoza ma geometry.

Muzitsulo zamakono zowonongeka pali ziwerengero zambiri zomwe sizipezeka mu CRTs. Ichi ndi chifukwa cha kusiyana kwakukulu mu teknoloji. Momwemo, mitundu yotsatira ya matrices ndi yosiyana: TNs yodalirika, IPS yolonjezedwa, zosiyanasiyana VA kusintha. Mmodzi wa iwo ali ndi zikhalidwe zake zokha, zomwe ndi zofunika kuziganizira pamene mukugula LCD kufufuza.
