Teknoolajiyada Alternative: LCD-soo bandhigay, ama "plasma"?

Maanta ay jirto su'aal ku jirin in ka sii wanaagsan tahay - monitor CRT ama LCD-soo bandhigay. Waayo, user celceliska doorashada waa wax iska cad. technology-soo-saarka LCD joogto ah waa hagaajinta iyo fureysaa jahooyinka cusub oo duurka ku. Waa maxay rajada waxaa suurto gal ah, marka sii horumariyo? Waa LCD in ay si guul leh u tartamaan la teknoolajiyada kale kartaan?

Ubadatay gaabiyay LCD (Liquid Crystal Display) waa si fiican loo garanayo ee dareeraha ah crystal bandhigay. Abuurtay technology this ayaa waqti dheer ah, laakiin ay sabab u tahay dhibaatooyinka ku-soo-saarka warshadaha ayaa helay codsi ballaaran. screens Small kiristaalo sida loo arki karaa on saacba digital waqtiga. Waxay ahaayeen madow iyo caddaan iyo jiray muddo kooban ah. Isla mar ahaantaana jiraan noocyo badan iyo tayo-sare ee dhuumaha ray cathode (CRTs), kuwaas oo si tartiib tartiib ah ay qabsadeen ku dhowaad suuqa oo dhan.

horumarinta technology LCD dhacay muddo ku dhow 30 sano oo keentay in natiijada riwaayado. Si aad u taariikhda, LCD-soo bandhigay ku dhawaad gabi ahaanba bedelay ay tartan electronic ka khaanadaha dukaanka. Waxay leedahay qaab fiican oo tartankii qalabka kale.

Modern LCD-bandhigay on-beegyada uu u fog ka horreeyay ee madow iyo caddaan,

1. Waxa uu bilaabay in ay u adeegaan dheer.
2. Si joogta ah hagaagtay xalinta screen iyo size.
3. Nuurkii waa ineysan si monitor CRT ah.
4. Marka la barbardhigo Good (250: 1).
5. xagal daawashada u fiican (120 digrii).
6. size yar yar oo fudud.

Si aad u taariikhda, LCD-bandhigay waa soo jiidasho inay iibsato a badan monitor CRT ah. kale waxay noqon kartaa oo kaliya screen plasma ah, laakiin hirgelintiisa la taaban karo, taas oo ka dhergin doonaa baahida tiro balaadhan oo ah dadka isticmaala, wuxuu noqon doonaa waqti dheer. technology ee ay wax soo saarka waa mid aad u qaali ah oo wakhti dheer qaata, waxa ay leedahay isticmaalka a awood sare, iyo dhibaatooyin la xiriira dhalmada midabka waxaa la mid ah sida in ka mid ah tartamayaasha kale. Intaa waxaa dheer in ay "plasma" waxaa aad u adag in la gaaro xal sare. Its faa'iido weyn waa dhalaalka sare oo ka duwan. By dhimaya this ka hor kale waa nooc ka mid ah kormeerayaasha. Laakiin on dhinacyada ku LCD-qaab yihiin madaxda, waxay ka badan ayaa is haysta iyo "plasma", iyo CRT yihiin. Sidoo kale waa in la ogaadaa iyo ammaankooda dhamaystiran caafimaadka aadanaha. Iyagu ma abuuraan shucaaca waxyeelada leh iyo beeraha electromagnetic.

Laakiin in wax soo saarka kasta waxay leedahay cillado ay, ka kaas oo aad aan uga takhalusi karo of. Ka hor inta aadan iibsan a LCD-soo bandhigay, ogow joogitaanka pixels "jabay". Waxaa la rumeysan yahay in mid ka mid daaha, waxaa waa in aanay noqon in ka badan saddex. Si ay iyaga la kala saaro inta kale waa mid fudud ilaa xad - pixels waxaa mar kasta iftiin leh midabka hal kaliya. Tijaabi shaashadda, beddelo image ah nooca la mid ah, iyo dooran ugu tayada sareeya.

Technology ayaa rajada xiiso emitting balaastigga (Light Emission Plastics). Waa joogto ah, iyo shirkadda Cambridge Technology Display ayaa horumar badan jihada this. luminosity ee screens kuwan ayaa si tartiib ah sara kacay, oo gaadhay heer uu Kokes casriga maanta.
