Isebenza njani imisebenzi yekristale

I-Crystal yekristali ye-crystal (i-LCDS) iye yaba yinxalenye yobomi bethu bemihla ngemihla, kwii-smartphones kunye neetekhnoloji kwiimowudi zekhompyuter kunye nemiqondiso yedijithali. Oku kubonisa ukuba zibonelela ngemifanekiso yokusombulula ephezulu kunye nemibala esebenzayo kunye nee-engile ezigqwesileyo. Kodwa ukhe uzibuze ukuba isebenza njani iimolekyuli ze-LCD?

Kwintliziyo ye-LCD ziimolekyuli zekristali, ezahlukileyo kubuchule babo bokuzilungelelanisa kwicala elithile xa liphantsi kwendawo yombane. Ezi molekyuli zenziwa ngamacandelo amade, anjengentonga efana nolwelo kunye nepropathi eqinileyo. Kwimeko yabo yendalo, iimolekyuli zekristali yolwelo zijolise ngokungacwangciswanga, ezikhokelela kwimbonakalo emnyama xa ukukhanya kudlula kubo.

Ukuqonda ukuba iimolekyuli ze-LCD zisebenza njani, makhe siqwalasele indlela esisiseko yephaneli ye-LCD. Ineplate ezimbini zeglasi kunye ne-suble encinci ye-storical ye-storical yesandwich phakathi kwabo. Umphezulu wangaphakathi weplate nganye yeglasi idityaniswe ne-elektrode ebonakalayo, evumela umhlaba wombane ukuba usetyenziswe kwi-crystal yolwelo.

Imolekyuli yekristali ye-lelstal kwi-LCD iqhelekile kwiindidi ezimbini: i-nematic ejikiweyo (i-ted) kunye nolungelelwaniso oluthe nkqo (VA). Kwi-TN LCD, iimolekyuli zihambelana kwikona ethile, zihlala zingama-90 degrees, phakathi kweepleyiti ezimbini zeglasi xa kusetyenziswa intsimi yombane. La malungiselelo ajijekileyo ivumela ukukhanya ukuba kudlule kwi-crystal yekristale kwaye ufikelele kumbukeli. ( Jonga ividiyo apha )

Xa intsimi yombane isetyenziswa kwi-TN LCD, iimolekyuli zekristali yolwelo ziqala ngokungaphumeleli, zilungelelanise ngokuhambelana necandelo lombane. Olu tshintsho ngolungelelwaniso lwepoliji yokukhanya kokukhanya kwi-crystal yolwelo, ukuyivala ngokufezekileyo ekufikeleleni kumbukeli. Ngokulawula umhlaba wombane, isixa sokukhanya kokukhanya kwi-LCD silawulwe ngokuchanekileyo, sikhokelela kwimigangatho eyahlukeneyo yokuqaqamba.

Kwelinye icala, i-LA LCDS isebenza ngokwahlukileyo. Kwi-VA LCD, iimolekyuli zekristale zekristali zilungelelaniswe ngokuthe nkqo, i-petpendicular kwiipleyiti zeglasi. Xa kusetyenziswa intsimi yombane, iimolekyuli ze-molekyuli, zivumela ukukhanya ukuba kudlule kwi-crystal yolwelo. Ifana ne-TN LCDs, inqanaba le-twit linokulawulwa ngokuhlengahlengisa umhlaba wombane, ngaloo ndlela ilawula ukuqaqamba.

Ukuphucula ukomeleza ukusebenza kwe-LCDs, izinto ezongeziweyo ezinje ngeefilitha zemibala kunye neenkqubo zokubuyela umva zifakiwe. Iifilimu zemibala zisetyenziselwa ukwenza umbala onqwenelekayo ngokuhamba ngokukhethekileyo ukucoca i-crystal yolwelo. Iinkqubo ezingasemva kweenkqubo, ziqhele ukudityaniswa kwe-LED, zibonelela ngokukhawulezileyo okufunekayo kwiphaneli ye-LCD.

Kwisishwankathelo, iimolekyuli ze-LCD zisebenza ngokulungelelanisa ulungelelwaniso lwezakhi zekristali yolwelo ngokusetyenziswa kwendawo yombane. Olu lungiselelo lolawulwa luvumela i-LCD ukulawula ukuhamba kokukhanya, kukhokelela ekubonakaliseni imifanekiso kunye neevidiyo. Ukukwazi ukulawula ngokuthe ngqo ukuqhelaniswa kweemolekyuli zekristali zenze i-LCDS yenye yezona teknoloji zithandwayo, zinikezela ngeempawu ezisemgangathweni eziphezulu kuluhlu olubanzi lwezixhobo.
