Iikhamera zedijithali zazisa ezininzi izinto ezibonakalayo kwilizwe lokufotowa, kuquka ukukwazi ukujonga umfanekiso owutshilele ukuzityhila ukuba ukhangele kakuhle phambi kokuba uqhubele kwenye indawo. Ukuba umntu wayevaliwe amehlo okanye ukuba ukubunjwa akukhange kubonakale kunene, unokwenza nje uqale umfanekiso. Isihluthulelo salolu hlobo ngumboniso wesikrini. Qhubeka ufunda ukuqonda ukuba yiyiphi i-LCD?
Ukuqonda ikhamera & # 39; s LCD
I-LCD, okanye i-Liquid Crystal Display, bubonisa iteknoloji yesiboniso ekwenzeni izikrini ezifakwe ngaphakathi emva kwayo yonke ikhamera yedijithali. Kwikhamera yedijithali, i-LCD isebenza ukuphonononga iifoto, ukubonisa iindlela zokukhetha imenyu, nokukhonza njengesikrini sokubukela esibukhoma.
Zonke iikhamera zedijithali ziqukethe izikrini zokubonisa imibala epheleleyo. Enyanisweni, isikrini sesiboniso sibe yindlela ekhethiweyo yokuqulunqa umcimbi, njengokuba kuphela inani elincinane leekhamera zedijithali ngoku ziqulethe i-viewfinder ehlukeneyo. Ngokuqinisekileyo ngeekhamera zefilimu, zonke iikhamera kufuneka zibe nesibhengezo sokukuvumela ukuba ulungise indawo.
Ukubukeka kwesikrini seLCD kuxhomekeke kwinani leepekseli i-LCD ibonisa, kwaye le nani kufuneka ibhalwe kwiinkcukacha zekhamera. Isikrini sokubonisa esinama-pixels angaphezulu kwesisombululo kufuneka sibe nesibindi kunomnye ngamaphikseli ambalwa.
Nangona ezinye iikhamera zingaba nekrini ebonisa ukusetyenziswa kweteknoloji ebonakalisa i-LCD, i-LCD yegama liye lalingqamana nezikrini zokubonisa kwiikhamera.
Ukongezelela, ezinye iikhamera ezidumileyo zingasebenzisa ukuboniswa kwebala lesikrini okanye umboniso ocacileyo , apho isikrini sinokuthi sitshintshe kwaye sishiye kude nomzimba wekhamera.
LCD Technology
Ukubonakaliswa kwekristal yamanzi kuyisebenzisa i-molecule yamanzi (i-crystal liquid substance) ebeka phakathi kwama-electrode amabini, avulekileyo. Njengoko isibonakaliso sisebenzise intlawulo kagesi kuma-electrodes, iamolekyuli ze-crystal zamanzi ziguqula ukulungelelaniswa. Inani lemali yombane inquma imibala eyahlukileyo ebonakala kwiLCD.
I-backlight isetyenziselwa ukufaka ukukhanya emva kocingo lwekristal yamanzi, ukuvumela ukuba isibonakaliso sibonakale.
Isikrini sokubonisa sibandakanya izigidi zamaphikseli , kwaye nganye pixel nganye iya kuba nombala ohlukileyo. Unokucinga ngalezi pixels njengamaqhosha athile. Njengoko amachaphaza abekwa ngaphaya komnye kwaye ahambelane, ukudibanisa kweefayile zepikseli zenza umfanekiso kwiskrini.
I-LCD ne-HD Resolution
I-HDTV inesisombululo se-1920x1080, esibangele i-pixels engama-2 yezigidi. Nganye yale pixel nganye kufuneka ishintshwe eziliqela ngezihlandlo nganye kwisibini ukubonisa into ehambayo kwiskrini ngokufanelekileyo. Ukuqonda indlela i-screen ye-LCD esebenza ngayo iya kukunceda uqonde ubunzima beeteknoloji esetyenziselwa ukudala umboniso kwisikrini.
Ngesikrini sokubonisa isikhamera, inani lamaphikseli ukusuka kuma-400,000 ukuya ku-1 million okanye ngaphezulu. Ngoko ikrini yekhamera ibonisa isiqulatho se-HD. Nangona kunjalo, xa uqwalasela ikhamera yekhamera ngokuqhelekileyo iphakathi kwee-3 no-4 intshi (ukulinganiswa ngokulinganayo ukusuka kwikona enye ukuya kwelinye icala), ngelixa i-screen yeTV ihlala phakathi kwe-32 no-75 intshi (ubuye iphinda ilingane), unokubona ukuba kungani ikhamera ukubonakala kubonakala kubukhali. Ucubungela malunga nehafu yeepekseli kwi-space ephindaphindiweyo ezincinci kunekrini leTV.
Ezinye izinto zokusebenzisa iLCD
I-LCD ziye zaba yinto eqhelekileyo yokubonisa iteknoloji kwiminyaka. I-LCD ivela kwiifayile ezininzi zedijithali. Isikrini seLCD sihlala ngaphakathi kwesikimu kwaye sibonisa iifoto zedijithali. I-teknoloji yeLCD nayo ibonakala kwii-televisions ezinkulu zeefowuni, izikrini zekhompyutheni kunye nezikrini ze-smartphone.
