Madzi a m'magazi kapena LCD - kusankha kovuta

Monga mwakachetechete "ndi kumizidwa mu chisokonezeko," nthawi ya utoto mawailesi akanema, ndipo pang'onopang'ono akugwa mafoni mafashoni ndi CRT ochiritsira. The mbadwo watsopano wa ma TV lathyathyathya-gulu ayamba msika TV. mitengo awo alibe chidwi kwambiri ndi ogula ambiri akuganiza zimene kusintha awo chakale "bokosi". Ndipo apa funso n'lakuti: umene uli bwino - plasma kapena LCD TV.

Ndipo kuthetsa vuto limeneli, tiyenera kumvetsa zimene zikusiyana pakati pawo. Ndipo pali kusiyana pakati pa iwo, ndipo iwo MUKACHULUKIDWE mfundo chosiyana kudyetsa chifanizirocho chophimba. Aliyense wa matekinoloje ali ndi ubwino ndi kuipa. Ndipo kudziwa kusiyana pakati pa plasma TV pa LCD ndi pang'ono zambiri mbiri ya matekinoloje.

luso LCD wakhala amadziwika pa zaka handiredi, kuyambira 1904. Poyamba, timibulu madzi yapangidwa kuti mufotokoze "akufa" fano. Chimasonyeza ulonda ndi toŵerengera. Izi inapitirira kwa zaka zambiri mpaka njira imeneyi anayamba kugwiritsidwa ntchito kwa oyang'anira kompyuta poyamba, ndiyeno ndi TV ochiritsira.

Chabwino, "plasma" luso chinamasulidwa mu 1964. Koma kwa nthawi yoyamba kwa TV ntchito mu 1998, pa Zima Olympic mu Nagano. Njira imeneyi kunapangitsa kuti zimafalitsa zithunzi pa lalikulu chophimba, kukula kwa imene ndi ma TV chikhalidwe analipo.

Ndipo tsopano, mtengo wake kupita pa magawo zofunika ma TV amene chidwi ogula. Ndipo mmodzi wa iwo ndi kukula chophimba. Mu atasemphana - plasma kapena LCD - plasma kuwatsogolera. Choyamba, gawo osachepera nsalu yotchinga madzi ndi 32 mainchesi. Chachiwiri, ma TV plasma ndi opendekera mainchesi 42 akadali mtengo kuposa LCD-ma TV ndi miyeso chomwecho. Koma ndime yoyamba sikuti ntchito pa plasma lapansi. Ndipotu, osati aliyense akusowa TV chachikulu, ndipo si onse amene angakwanitse. Choncho, mu gawo msika wa ma TV ndi zowonetsera yaing'ono wosiyana mpikisano timibulu madzi akhoza kufika yekha zabwino kinescopes akale.

Madzi a m'magazi kapena LCD - umisiri ziwiri izi anayeza osati kukula. magetsi ndi sali chinthu lomaliza. Ndipo ngati posachedwapa anawomba nsalu plasma owerengera mofulumira LCD-ma TV, ndipo tsopano mu mowa magetsi pafupifupi wofanana. Komanso chotero chizindikiro ndi moot monga mbali TV yakanema. Ndi plasmas pano chirichonse chiri bwino - iwo amakhala mu osiyanasiyana madigiri 160. Ndipo ena opanga LCD-zowonetsera kulengeza kuti ali ndi choonera mopendekeka ndi madigiri 178. Koma Chiwerengerochi ena funso. Ndipotu fano zowonetsera ngati amaziralira ndipo wotaya Mosiyana pa kwambiri kumathandiza kupeza ngodya zabwino ang'onoang'ono.

anthu ambiri amene anapanga izo pa TV wakuda ndi woyera, kumbukirani angati anali "umboni" ndiye ndi "Birches". utali wamoyo awo ndi zaka zambiri. Tsopano wina amene anakumana ndi kusankha - plasma kapena LCD ndinkadabwa angati amene adzatumikira kupeza wake watsopano. Opanga LCD-kusonyezedwa kulengeza kuti 'mwana' amagwira ntchito kwa zaka 40, ngati iwo monga maola 4 tsiku lililonse. Pa nthawi yomweyo moyo wa madzi mapanelo anasonyeza akuti ndi kawiri zochepa. Koma kutsimikizira mfundo imeneyi zitha kukhala mu zaka 10-20, pamene woyamba "yaitali yaitali" tili ndi "chikumenyana maphwando". Ndipo tsopano ife tikhoza motsimikiza chinthu chimodzi chokha - LCDs kodi ndi moyo wautali.

Mbali ina yofunika ya vuto - plasma kapena LCD ndi mtundu kubalana. Pa chizindikiro ichi mwapadera Umapeza plasma. Izi zimatheka ndi ndondomeko kuwala Letsani mu mapanelo amenewa. Mu plasma, ndi pixels amangokhala anatembenuka, ndi zina chophimba si anati kunja zowunikira. Mu LCD luso kuwala zonse likulowerera mu ming'alu ya zosiyanasiyana mapikiselo. Kamakupatsani mtundu afiira ndi kupotoza mithunzi achilengedwe.

Pa nthawi yomweyo, madzi zowonetsera akhoza kukhala ndi mavuto amatopa. Amenewa zingachitike ngati nthawi yaitali "akulendewera kunja" malo amodzi chithunzi. Ndipo phosphors "zisathe" chifukwa cha kwambiri "ntchito". Adzatsogolera chakuti patapita kanthawi pa zenera adzakhala kuonekera silhouette chithunzi posungira. A LCD-ma TV ichi "matenda" si bwanji. Komanso, ambiri a zoikamo zimadalira TV a Mlengi kukhulupirika kwake. Ndipo inakwaniritsidwa umisiri onse. Ndipo tichisankhe, aliyense ali ndi ufulu wosankha zokha.
