Midableh-LCD: tilmaanta, mabda 'hawlgalka

In qalabka casriga ah qoyska loo element ah sida a midableh-soo bandhigay. Waxa loo isticmaalaa in noocyada kala duwan ee qalabka: Kormeerayaasha computer, telefishannada, screens telefoonka mobile, in kaamirada iyo kamaradaha, iyo sidoo kale qalab kale oo badan. Waa maxay nooca technology, maxay yihiin faa'iidooyinka? In this article, waxaan baari doona waxa a midableh-LCD, faa'iidada iyo khasaaraha ay.

transistor dhuuban-filimka (midableh) turjumay afka English ka dhigan tahay dhuuban-filimka transistor. Kuwaas waxaa xubno ka samaysan yihiin oo dhumucdiisuna waxay film dhuuban ee 0.1-0.01 micrometer. transistors Halkan sida oo ay gacanta ku midableh-furta, weli waxa loo yaqaan "firfircoon". Dadban ka mid ah qalabka dareeraha ah crystal. Active midableh-soo bandhigay, in la barbardhigo technology LCD ee, uu leeyahay xawaare aad u weyn, Hufnaan a badan oo ka duwan oo ah image iyo xagal daawashada si weyn u ballaaran. In qalabka ma jiraan wax flicker screen, kaas oo indhaha u daalan. In firfircoon pixel furta shucaaca dhalin daadanayo iftiin la midabka ah loo dejiyay, sidaas midableh-bandhigay waa wax badan sii dhalaal badan LCD furta dadban. faa'iidooyinka Kuwan oo dhammu waa ay sabab u tahay xaqiiqada ah in technology lagu tilmaamay heerka sare image helid. Tan waxa u sabab xaqiiqada ah in dhibic kasta oo soo bandhigay waxaa ay gacanta ku transistor gaar ah oo khafiif ah filimada. Tirada xubno sida in midableh-technology waa saddex jeer ka badan tirada pixels. unugyada Sidaa darteed, ciyaar hal dhibic saddex midab, casaan, (nidaamka RGB) cagaaran iyo buluug. Tusaale ahaan, ka fiirsan shax: bandhigay midableh (color) oo leh xal of 1280x1024 pixels, siday u kala horreeyaan, tirada transistors in qalab noocan oo kale ah waxay noqon doontaa 3840h1024.

The Matrix crystal dareere ah marka hore u muuqday sanadkii 1972. Tan iyo markaas, technology ayaa si weyn u fartaan iyo bedelay. Si kastaba ha ahaatee, dhammaan macquul ma ahan in la baabi'iyo qabsoomi. Tusaale ahaan, ay sabab u tahay tirada badan oo pixels badanaa waa iyaga ka mid ah waxaa laga heli karaa "jabay", in waa la jebiyey. dhibic kharribay noocan oo kale ah lama hagaajin karo. Waa in la ogaadaa in on furta oo firfircoon pixels "jabay" ka yar dareemi badan qalabka dadban ama qaab, dual scan. horumarinta joogtada ah ee midableh-technology ayaa si weyn u dhimay qiimaha saara kormeerayaasha sida hadda "qaali qalaad" waxa uu noqday mid caadi ah. factor muhiimka ah ee maxalka furta oo firfircoon baahsan in industry ahaa istareexsan ee la isticmaalo. Maalmahan ninna la yaabay by taabashada shaashad midableh-soo bandhigay, iyo labaatan sano ka hor, waxa uu ahaa guul ah. touchmonitors Rasprostanenie Horeeyey muuqaalka kore ee lagu daydo, oo awood u leh oo ka hawlgala deegaanada adag. Natiijada waxa ay aheyd unug midableh-soo bandhigay, isku hab ay ugu soo bandhigaan warbixin muuqaal ah, iyo qalabka la gelin ah (keyboard). qaadista heerka nidaamka noocan oo kale ah waxay bixisaa xakamaysada ah interface serial. Tani qalab on hal gacan ku xiran yahay in ay monitor oo kale - si ay dekedda serial (COM1 - COM4). Si loo xakameeyo iyo calaamadaha fasirid ka shidma, iyo sidoo kale xakamaynta of "cigta" waxaa loo isticmaalaa PIC-ilaaliyaal. Waxay awoodaan in ay bixiyaan xawaaraha sare iyo saxsanaanta ee go'aaminta dhibcaha la taabto waa.

Gebogebadii, waxaannu nidhaahnaa midableh-technology sida bandhigay iyo dareemayaal jira oo dhan nagu wareegsan nolol maalmeedka, waxay waxaa loo isticmaalaa in shiidaa qalabka kasta oo guriga ku nool.
