Ogula Kusankha: LCD oyang'anira

Makompyuta mu moyo wa munthu uyu mu msewu ndi mbali ya izo. Pakali pano, makonda kwambiri analandira LCD-oyang'anira pakati oyang'anira kompyuta. zosintha amakono awa ndi zinthu zambiri pa akapolo anzawo akale. Iwo amasiyana Chrixitu.

Childs, ogula amene asankha mtundu uliwonse yogula, kuwatenga pazipita zotheka phindu. Koma polojekiti, pali choyamba, makasitomala ambiri amachita chidwi, zomwe polojekiti ndi bwino kuti maso, monga ambiri akudziwa mavuto zotheka chifukwa cha kuthera nthawi zambiri pa kompyuta. Mosakayikira, mu gulu ili LCD-oyang'anira ali bwino kuposa anthu pa chifukwa cha amene ali ndi cathode ray chubu. Chifukwa mbali structural, LCD zowonetsera sabala mpweya uliwonse. Chinthu chokha chimene zingakhudze diso la ogula, izo kunja kukuzizira, nthawi zina analenga pamene kusintha kuwala. Koma zotsatira izi zikhoza kupewedwa ndi kusintha kolowera izi si mu zoikamo polojekiti, ndi zoikamo kanema khadi. Mu CRT oyang'anira kukulowa zimadalira makhalidwe monga mlingo kulunzanitsa wa nsalu yotchinga ya polojekiti, ndi kupewa zotsatira zoipa zitha kukhala pa nkhani ya kugula losatheka mtengo. Kumene, lero si njira yabwino. Mwachidule kugula anasonyeza madzi galasi.

Choyamba, kusankha LCD-oyang'anira, muyenera khutu ku mtundu wa masanjidwewo, zomwe zimakhudza mtengo komanso makhalidwe ena monga kuonera njingayo, Mosiyana, mtundu kubereka, kuwala, nthawi Poyankha, ndi zina zotero.

Mwina chizindikiro chokha chimene LCD-oyang'anira otsika CRT ndi kuonera njingayo. Izi umatheka kukhazikitsa mbali zina za umisiri zitsulo. Pafupifupi onse a gulu LCD pamene muyang'ana pa ngodya lalikulu adzakhala molakwika fano. Koma opanga zikukangalika ntchito kuthana vuto limeneli ndipo zikuoneka kuti posachedwapa padzakhala zitsanzo pafupifupi opanda cholakwa.

Chimodzi mwa magawo kwambiri pochita kusonyezedwa madzi galasi ndi nthawi zimene galasi lapansi. Mlingo wabwinobwino wa zosakwana 30 milliseconds. More nthawi mwina chifukwa cha kuonekera kwa akuchedwa kwambiri ndi kusinthana kudya mafano ndi mafelemu.

opanga Modern kugawanitsa LCD-kusonyezedwa monga mwa masanjidwewo mtundu TN, IPS ndipo * VA (Ofukula mayikidwe). Gulu loyamba oyang'anira ali mtengo kwambiri zosangalatsa. Mtundu wa mawerengetsedwe amakhala ndi wotsika mowa mphamvu ndi Poyankha nthawi ya makhiristo. Kuipa monga zolakwika mtundu Pamanja yaing'ono kuonera ngodya ndi kusiyana mokwanira otsika. Mwazina, akhungu mawanga, monga ulamuliro, mowirikiza moto. Pa banja IPS kungakhale chizindikiro chabwino kudziwa kwambiri mtundu, komanso njira mwachilungamo lalikulu. Chizindikiro Poyankha nthawi kuposa mitundu ina ya m'mbuyomu mawerengetsedwe, ndi kusiyana ndi zosakwana * VA. A mwayi chidwi n'chakuti pixels mdima ndi zolakwa mapikiselo. Mtundu yotsirizira ya masanjidwewo ali kwambiri mtundu kubalana pa kusiyana mwachilungamo mkulu. Mabaibulo onse a m'banjali apangidwa ndi opanga osiyana kuonjezera makhalidwe ntchito ya pachiyambi koma makamaka wolemekezeka.

Kusankha ina mtundu wa masanjidwewo, zikhazikitsidwe ntchito zina. Ngati muli ndi ntchito makamaka ndi pulogalamu ofesi, waukulu kusankha muyezo adzakhala mtengo ndi maonekedwe, monga makhalidwe ena mu nkhani iyi si mfundo. Pankhaniyi, muyenera kulabadira kuwunika Makampani Acer (Acer P196HQVb, Acer P226HQbd, Acer A191HQLb) ndi Samsung (Samsung S19A100N, Samsung B1930N, Samsung S20A300N). Ntchito polojekiti makampani kufalitsa kumene ndi fundo yofunika kwambiri ndi mtundu Pamanja, Ndi bwino kusankha oyang'anira ndi luso masanjidwewo IPS, mwachitsanzo, (Asus VS209N, LG IPS225T, HP ZR2240w). Pakuti kompyuta yabwino kwambiri kunyumba liyang'anire masanjidwewo mtundu * VA (Samsung F2080, NEC EA191M), chifukwa zoona, chilengedwe lomwe likukwaniritsa zofunikira za opanga masewera ndi anthu amene amakonda kuona zithunzi ndi mavidiyo.
