Indlela Yokuqhathanisa Izibukeli Zama-LCD Ngokusekelwe Emininingwane Yokuthola Okwakho
Ngokuthuthukiswa kokukhiqiza, ubukhulu bephaneli le-LCD baqhubeka bekhudlwana konke kuyilapho amanani eqhubeka ewa. Abadayisi nabakhiqizi baphonsa izinombolo eziningi nemigomo yokuchaza imikhiqizo yabo. Ngakho-ke, umuntu wazi kanjani ukuthi konke lokhu kusho ukuthini? Lesi sihloko sibheka ukumboza izisekelo eziyisisekelo ukuze umuntu enze isinqumo esinolwazi uma uthenga umcibisholo we-LCD kwideskithophu yakho noma njengesiboniso sesibili noma sangaphandle se-laptop.
Usayizi weskrini
Usayizi weskrini yisilinganiso sezindawo ezibonakalayo kwesikrini kusuka ekhoneni elingezansi kuya ekhoneni elingenhla elingenhla lobukiso. I-LCD yanikezela ngezilinganiso zabo zangempela kodwa manje iqoqa lezo zinombolo. Qinisekisa ukuthi uthola ubukhulu obungokoqobo obubizwa ngokuthi usayizi weskrini wangempela noma kunini lapho ubheka i-LCD. Isibonelo, isibonisi esinama-23.6-intshi yangempela yesayizi yesikrini singathengiswa njenge-intshi engu-23 noma isibonisi esingu-24 intshi . Ubukhulu bephaneli lokubonisa ligcina linquma ubukhulu beqapha ngakho lokhu kungenye yezinto zokuqala okufanele zicatshangelwe. Ngemuva kwalokho, i-monitor ye-intshi engu-30 izothatha amadeski amaningi ngenkathi i-intshi engu-17 okungenani ingcono kunokuba ne-laptop.
Ukulinganisa kokulinganisa
Isilinganiso sesici sibhekisela kwinombolo yamaphikseli angemuva kuma-pixel aqondile ekubonisweni. Esikhathini esedlule, abaqaphi babesebenzisa okufanayo okuyi-4: 3 ububanzi bokubukeka njengama-televisions. Ababheki abaningi abasha basebenzise ububanzi obukhulu be-16:10 noma 16: 9. I-16: 9 yisilinganiso esivame ukusetshenziswa kuma-HDTV futhi manje sesivame kakhulu. Kukhona ngisho nabambalwa abanzi obubanzi noma abacwaningi be-21: 9 emakethe kodwa abajwayelekile kakhulu.
Izinqumo Zomuntu
Zonke izikrini ze-LCD empeleni zingabonisa kuphela isinqumo esisodwa esisinikeziwe esibizwa ngokuthi isinqumo sendawo. Lena inombolo yenyama yamaphikseli angama-horizontal futhi aqondile akha i-matrix ye-LCD yesibonakaliso. Ukubeka ukubonisa ikhompyutha kwisinqumo esingaphansi kwalokhu kuzobangela ukuthuthwa kwe-extrapolation. Le-extrapolation izama ukuxuba amaphikseli amaningi ndawonye ukukhiqiza isithombe ukugcwalisa isikrini njengokungathi kusesimweni sokuzalwa kodwa kungabangela izithombe ezibonakala zingabonakali.
Nazi ezinye zezinqumo ezijwayelekile zendabuko ezitholakala kuma-monitor e-LCD:
