TFT-LCD: inkcazo, isimiso yokusebenza

Xa zasendlini mihla kusetyenziswa ngokubanzi njengento efana TFT-umboniso. Kusetyenziswa iintlobo ezahlukeneyo izixhobo: esweni computer, iTV, screens mobile phone, xa khamera kunye iikhamera, kwakunye nezinye izixhobo ezininzi. Loluphi uhlobo iteknoloji, yintoni iingenelo? Kweli nqaku, siza kuhlolisisa into eyenza TFT-LCD, alungileyo kwakunye nangalunganga.

Thin-film transistor (TFT) itshintshelwe ulwimi IsiNgesi kuthethwa zibhityile-bhanya transistor. Ezi zinto zenziwa ifilimu ubukhulu obhityileyo 0.1-0.01 micrometer. transistors apha kwaye ilawulwa TFT-matrix, kodwa ibizwa ngokuba "elisebenzayo". Umsi zibandakanya izixhobo uboniso olunombala wamanzi. Active TFT-umboniso, ngokwahlukileyo kubuchwepheshe LCD, abe ngesantya esikhulu, kukho ingcaciso eliphezulu kakhulu kwaye nshita umfanekiso kunye ukubukela engile ebanzi kakhulu. Kwezi zixhobo akukho yokudanyaza screen, ukusuka apho emehlweni udiniwe. Xa matrix pixel okuvelisa radiation esebenzayo ekubhobhozeni ukukhanya nge eyahlukileyo umbala kwangaphambili, ngoko TFT-uboniso ngaba lubeka phi zava matrix LCD. Zonke ezi nezibonelelo ngenxa yokuba ubuchwepheshe echazwe uye ephakamileyo umfanekiso sihlaziya umyinge. Oku kungenxa yokuba ingongoma nganye isiboniso lilawulwa eyahlukileyo transistor umboniso obhityileyo. Inani izinto ezinjalo TFT-technology-phindwe kathathu likhulu kunenani of pixels. cells Ngoko ke, ngenqaku elinye umdlalo amathathu anemibala: obomvu, oluhlaza okwesibhakabhaka (RGB system). Ngokomzekelo, cinga matrix: uboniso TFT (umbala) enesisombululo ka 1280x1024 pixels, ngokulandelelana, inani transistors kwiphakati uya kuba 3840h1024.

Yokuqala olunombala wamanzi akhazimlayo matrix wabonakala ngo-1972. Ukususela ngoko, i-iteknoloji uye savela kakhulu and watshintsha. Noko ke, kwakungekho lula ukuphelisa esi iziphene. Umzekelo, ngenxa yenani elikhulu pixels amaxesha phakathi kwabo inokufumaneka "eyaphukileyo", oko yaphulwe. sezingeni ibhuqiwe ayikwazi inokulungiswa. Kufuneka kuqatshelwe ukuba isizalo esebenzayo ipixels "eyaphukileyo" angaphantsi buqapheleke ngaphezu izixhobo zezenzi okanye imiboniso, scan ezimbini. uphuhliso oluqhubekayo TFT-technology iye yehla kakhulu ixabiso ekuvezeni esweni ngoku "exotic oluziindleko" liye laba nezolo. Into ebalulekileyo kwi matrix esebenzayo ngokubanzi kushishino yaba lula ukusetyenziswa. Kule mihla akukho mntu kumangaliswa screen touch TFT-umboniso, iminyaka engamashumi amabini eyadlulayo, yaba ukuphumelela. Rasprostanenie touchmonitors ngaphambi ukubonakala imifuziselo, ekwaziyo ukusebenza kwiindawo ngqwabalala. Umphumo waba iyunithi TFT-umboniso, edibanisa iindlela ukubonisa ulwazi ezibonwayo, kunye isixhobo sokufaka (keyboard). Ukusebenza nkqubo inika umlawuli interface serial. Esi sixhobo kwi icala liqhagamshelene esweni kunye nezinye - ukuya uthotho lezibuko (COM1 - COM4). Ukulawula kunye zokucazulula imiqondiso wexesha elongezelelweyo lomenzi woluvo, kwakunye kwezithandani of "ebuyile" lisetyenziswa PIC-izilawuli. Bona banakho ukubonelela isantya esiphezulu kunye nokuchaneka ekugqibeni amanqaku kwebala.

Xa ndiqukumbela, sithi ukuba TFT-technology njenge umboniso kwaye utsale abenzi ke ngeenxa zonke thina kubomi bemihla ngemihla, ukuba zisetyenziswa phantse zonke izixhobo zasekhaya.
