Masanjidwewo - ndichiyani? mitundu ya mawerengetsedwe

Lero kuli kovuta kupeza munthu amene unali CRT polojekiti kapena CRT ma TV akale. Njira imeneyi msanga ndi bwino atathamangitsidwa zitsanzo za LCD, zomwe ndi zochokera timibulu madzi. Koma palibe masanjidwewo wosalemekezeka. ndi timibulu madzi ndi masanjidwewo chiyani? Zonsezi adzaphunzilanso pa nkhani imeneyi.

prehistory

Kwa nthawi yoyamba pa timibulu madzi, dziko anaphunzira mu 1888, pamene katswiri wotchuka Friedrich Raynittser anapeza kuli zinthu zachilendo zomera. anadabwa ake kuti ena zinthu, poyamba ndi dongosolo crystalline pamene usavutike kwathunthu kusintha katundu wawo.

Choncho, chinthu choyamba mutnelo pa kutentha madigiri 178 Celsius, ndiyeno kwathunthu anatembenukira kwa madzi. Koma chotulukira sinathe kumeneko. Anapeza kuti madzi zachilendo poyerekezera mu atomu kumaonekera ngati Krustalo a. Zinali ndiye kuti liwu loti madzi galasi.

Mfundo zikugwira ntchito ya LCD masanjidwewo

Mu ntchito iyi ndi yochokera masanjidwewo. ndi masanjidwewo ndi chiyani? Izi Mipikisano wofunika yaitali. Imodzi mwa mfundo zake - kope gulu, LCD polojekiti kapena nsalu yotchinga TV makono. Tsopano ife tikupeza, limene mfundo ya ntchito yawo.

Ndipo zachokera ochiritsira kuwala kugawanika. Ngati inu mukukumbukira sayansi sekondale, izo basi limatiuza kuti ena zinthu angathe kupatsira kuwala sipekitiramu chimodzi chokha. N'chifukwa chake polarizers awiri madigiri 90 zambiri sangathe kupereka kuwala. Kukachitika kuti ili pakati zina zilizonse zimene angathe atembenuza kuwala, tidzatha kusintha kuwala ndi magawo ena. Ambiri, izi ndi bokosi yosavuta.

Anasintha mawerengetsedwe chipangizo

Ochiritsira LCD nthawi zonse zigwirizana zigawo zingapo okhazikika:

• backlight.
• Amasonyeza yomwe pachilichonse zounikira tatchulazi.
• Polarizers.
• The gawo lapansi la galasi, kumtunda kumene ojambula conductive.
• A kuchuluka kwa galasi madzi ankhanza.
• Wina polarizer ndi gawo lapansi.

Aliyense mapikiselo zoterozo bokosi aumbike zofiira, zobiriwira ndi buluu pixels, mitundu umene umabala aliyense wa mitundu zilipo. Ngati inu kuyatsa zonse mwakamodzi, chifukwa ndi loyera. Mwa njira, kodi Maganizo a masanjidwewo chiyani? nambala ya pixels m'menemo (1280x1024 Mwachitsanzo).

Kodi masanjidwewo?

Mu mawonekedwe wosalira, iwo ali chabe (yosavuta) ndi akuchitachita. Chabe - mophweka kwambiri pixels awo adamulowetsa mwa ndondomeko, kwa mzere ndi mzere. Choncho, poyesera kukhazikitsa ulimi wa kusonyezedwa ndi lalikulu opendekera izo anasonyeza kuti ndi akanagwiritsa kuwonjezeka kutalika ochititsa lapansi. Chifukwa cha zimenezi, kwambiri osati kumawonjezera mtengo, koma akuchuluka voteji, zikubweretsa kuchuluka lakuthwa mu kusokonezedwa. A masanjidwewo chabe Choncho akhoza kugwiritsidwa ntchito mu yopanga kusonyezedwa yotchipa ndi opendekera yaing'ono.

Yogwira mitundu oyang'anira, TFT, amakulolani kusamalira aliyense (!) Mamiliyoni pixels payekha. chakuti aliyense mapikiselo ukugwira ndi transistor osiyana. Cell kuti asanakalambe kutaya mlandu, amene anali anawonjezera condenser osiyana. Kumene, likuvutika ngati ndale analephera mobwerezabwereza kuchepetsa Poyankha nthawi iliyonse mapikiselo.

masamu kulungamitsidwa

Mu masamu, bokosi ndi chinthu opezeka mu tebulo amene zolemba zili pa mphambano ya mizere ndi mizati. Tikumbukenso kuti mawerengetsedwe ambiri ankagwiritsa ntchito kompyuta. Chionetsero chomwecho angathe kutanthauziridwa monga masanjidwewo a. Popeza mapikiselo ali ndondomeko zina. Choncho fano lililonse kuti aumbike pa kuwonetsera laputopu, bokosi limene maselo zili mtundu uliwonse mapikiselo.

Aliyense mtengo amatenga ndendende 1 mamvekedwe a pamtima. A pang'ono? Kalanga ine, koma ngakhale mu nkhani iyi, chimodzi chokha chimango FullHD (1920 × 1080) Babulo adzakhala awiri MB. Ndipo mmene malo mudzafuna filimuyi kwa mphindi 90? N'chifukwa chake fano ali wothinikizidwa. kufunika yaikulu ndi determinant.

Mwa njira, kodi determinant a masanjidwewo chiyani? polenomiyo Izi kaphatikizidwe zinthu za bokosi lalikulu ngati kuti phindu lake mukusungira transposition ndi ma liniya mizere kapena mizati. Mu masanjidwewo mu nkhani iyi iwo anamvetsa mawu masamu Pofotokoza makonzedwe pixels imene mtundu wawo yosiyanasiyana. Square umatchedwa chifukwa chiwerengero cha mizere ndi mizati mu mofanana.

N'chifukwa chiyani zimenezi ndi zofunika? Mfundo yakuti 'kala' ikusonyeza ntchito Haar asinthe. Ndipotu, Haar kusinthika - ndi mfundo kukhota kotero kuti akhoza kukhala conveniently ndi chogwiritsira encode. The chifukwa ndi masanjidwewo orthogonal, umene decoding nthawi ntchito monga determinant lapansi.

Tsopano ife kuyang'ana chachikulu mitundu ya masanjidwewo (kuti ndi masanjidwewo yokha, taona).

TN + filimu

Mmodzi wa ambiri ndi wotchipa tsopano amasonyeza zitsanzo. Iwo ali ndi kudya Poyankha nthawi, koma osauka mtundu kubalana. vuto ndi timibulu mu masanjidwewo ndi anakonza kuti kumathandiza kupeza ngodya zabwino kuonera analandira negligible. Pofuna zodabwitsazi, ife anayamba filimu wapadera kuti amalola kuti mukulitse chiwerengero cha kumathandiza kupeza ngodya zabwino kuonera.

makhiristo mu masanjidwewo ndi anakonza mu mzati, potero kukumbutsa asirikali perete. makhiristo ndi anapotoza mu mwauzimu, kotero mwangwiro kugwiritsitsa zolimba mzake. zigawo bwino pafupi ndi gawo lapansi, ndi pamwamba pa iwowa akupanga recess wapadera.

Aliyense kusitalo wabweretsedwa elekitirodi malamulo a voteji kudutsa izo. Ngati palibe voteji, makhiristo ndi zimayenda ndi madigiri 90, umene ndi kuwala chitadutsa momasuka kupyolera mwa iwo. Likukhalira wamba woyera mapikiselo masanjidwewo. Kodi ofiira kapena zobiriwira? Monga likukhalira?

Kamodzi amayesetsa, wothinikizidwa helix, ndi psinjika chiŵerengero zimadalira mphamvu panopa. Ngati mtengo pazipita, timibulu zambiri zithe kupatsira kuwala, chifukwa mu wakuda maziko. Kuti mupeze mtundu imvi ndi mithunzi ake, udindo wa makhiristo mu mwauzimu ndi kusintha kuti kuchuluka kwa kuwala iwo anadutsa.

Mwa njira, ndi kusakhulupirika mu mawerengetsedwe izi zonse adamulowetsa mitundu onse, chifukwa mu mapikiselo woyera. N'chifukwa chake n'zosavuta kudziwa mapikiselo anatentha kuti nthawi zonse kumaonekera mwa mawonekedwe a mfundo owala pa polojekiti ndi. Popeza kuti mtundu kubalana wa mawerengetsedwe wa mtundu uwu nthawi zonse vuto, ndi zovuta ndi kukwaniritsa kusonyeza wakuda.

Pamalo mwanjira zolondola, akatswiri timibulu pabwino pa makona a 210 °, umene mtundu khalidwe ndi Poyankha nthawi kuchuluka. Koma mu nkhani iyi, sipanatenge popanda akalowa: mosiyana kwa chakale TN-mawerengetsedwe kuti vuto ndi mithunzi ya woyera, mitundu ndi kutsukidwa. Choncho luso DSTN. Kwenikweni ake ndi kuwonetsera kwa lagawidwa amachepetsa awiri, omwe ukulamulidwa payokha. Achikondi bwino kwambiri, koma kuchuluka kulemera ndi mtengo wa oyang'anira a.

Ndicho chimene masanjidwewo ndi mu laputopu TN mtundu + filimu.

S-IPS

Company Hitachi bwino wolema zolakwa za sayansi yapita, anasankha kuyesa kusintha izo, koma kuti mukupanga chinachake ukasintha latsopano. Makamaka Günther Baur mu 1971 anapeza kuti timibulu akhoza adzaikidwa osati mu mawonekedwe a mizati zopotoka, ndipo anaika kufanana ndi mzake pa gawo lapansi galasi. Kumene, mu nkhani iyi, ndi popereka maelekitirodi amagwira.

Ngati woyamba polarizing fyuluta, palibe voteji, kuwala chitadutsa momasuka mu izo, koma anachedwa ndi gawo lapansi chachiwiri, kugawanika ndege amene nthawi zonse chimafikira pa makona a madigiri 90 poyerekezera ndi woyamba. Chifukwa cha zimenezi, kwambiri osati kumawonjezera liwiro la ntchito ya polojekiti, koma wakuda - kwenikweni wakuda, osati kusuntha mdima imvi mtundu. Komanso, mwayi ndi kumathandiza kupeza ngodya zabwino zambiri za view.

zolakwa luso

Kalanga ine, mu timibulu iwonso amene anakonza kufanana ndi mzake, zimatenga nthawi zambiri. Ndipo chotero Poyankha nthawi pa chitsanzo akale amakwaniritsa ndi chofunika kwambiri cyclopean 35-25 MS! Nthawi zina ankatha kuona ngakhale ku njira ya cholozera, tiyeni okha zithunzi zazikulu mu zidole ndi mafilimu kuti owerenga bwino kuiwala.

Popeza maelekitirodi ali oyenerera pa gawo lapansi chomwecho, pamafunika mphamvu zambiri atembenuza makhiristo m'njira ankafuna. Ndipo chifukwa oyang'anira onse pamaziko a IPS-masanjidwewo kawirikawiri kupeza Energy Star nyenyezi kwa dzuwa. Kumene, kuzindikiritsa gawo lapansi ali kunatanthauzanso ntchito nyale wamphamvu kwambiri, ndipo zilibe kusintha zinthu ndi mowa mkulu mphamvu.

Workability kupanga mawerengetsedwe ngati mkulu, choncho, mpaka posachedwapa anali kwambiri, okwera mtengo kwambiri. Mwachidule, ndi ubwino onse ndi kuipa kwa oyang'anira amenewa ndi abwino okonza: mtundu khalidwe ali kwambiri ndi Poyankha nthawi zina, mukhoza ndalama.

Ndicho chimene IPS-masanjidwewo.

MVA / PVA

Popeza kuti tonse a mitundu pamwamba pa mawerengetsedwe ndi zovuta kuti kuthetsa zosatheka latsopano Fujitsu Technology anayamba kupanga. Ndipotu, MVA / PVA ndi Baibulo kusinthidwa wa IPS. Chachikulu kusiyana - ndi maelekitirodi. Iwo zili pa gawo lapansi chachiwiri mu mawonekedwe a Triangles pachiyambi. njira mosavuta kuyankha makhiristo kusintha voteji, ndi mtundu mamasuliridwe ukhale wabwino kwambiri.

makamera

Ndipo kodi masanjidwewo mu kamera? Pankhaniyi, choncho amatchedwa galasi wochititsa yomwe imatchedwanso mlandu zolumukizidwa chipangizo (CCD). Kuposa kamera masanjidwewo maselo zambiri, ndi bwino. Pamene shutter atsegula, umadutsa otaya masanjidwewo wa ma elekitironi: kwambiri kwambiri panopa akuwuka. Choncho, m'madera mdima wa panopa aumbike. Land masanjidwewo tcheru mitundu ina, ndi chifukwa kupanga chithunzithunzi wathunthu.

Mwa njira, kodi kukula kwa masanjidwewo, ngati tikukamba za kompyuta kapena Malaputopu? Ndi yosavuta - otchedwa opendekera chophimba.
