Kubomi bemihla ngemihla nasemsebenzini, sihlala sidibana neentlobo ezahlukeneyo zokubonisa ikristale engamanzi (LCDs). Nokuba iiselfowuni, oomabonakude, izixhobo zombane ezincinci, izixhobo zokubala, okanye iithermostats zomoya womoya, ubuchwephesha beLCD bamkelwe ngokubanzi kwiinkalo ezahlukeneyo. Ngeentlobo ezininzi zezikrini ezikhoyo, kunokuba ngumngeni ukwahlula phakathi kwazo. Ngokubanzi, nangona kunjalo, banokuhlelwa kwiindidi ezininzi eziphambili, njenge-LCD yekhowudi yecandelo, izikrini ze-dot matrix, iiLCD ze-TFT, ii-OLED, ii-LED, i-IPS, kunye nokunye. Ngezantsi, sazisa ngokufutshane ezinye zeentlobo eziphambili.
Ikhowudi yecandelo LCD
Ikhowudi yecandelo i-LCDs yaphuhliswa okokuqala eJapan kwaye yaziswa eChina ngeminyaka yoo-1980. Ikakhulu yayisetyenziselwa ukutshintsha iityhubhu zedijithali ze-LED (ezakhiwe ngamacandelo angama-7 ukubonisa amanani 0-9) kwaye zixhaphake zifumaneka kwizixhobo ezinjengezibali kunye neewotshi. Umxholo wabo ulula. Zikwabizwa ngokuba zii-LCD zodidi lwecandelo, iiLCD ezinobungakanani obuncinci, izikrini ezinoonobumba abasi-8, okanye iiLCD zohlobo lwepateni.
Isikrini seDot Matrix
Izikrini zematrix yedot zinokwahlulwa zibe yi-LCD dot matrix kunye neentlobo zamachaphaza e-LED. Ukubeka ngokulula, zibandakanya igridi yamanqaku (iipixels) ezilungiselelwe kwi-matrix ukwenza indawo yokubonisa. Ngokomzekelo, isikrini esiqhelekileyo se-LCD se-12864 sibhekisela kwimodyuli yokubonisa kunye namanqaku angama-128 anqamlekileyo kunye namanqaku angama-64.
TFT LCD
I-TFT luhlobo lwe-LCD kwaye isebenza njengesiseko setekhnoloji yekristale yolwelo yanamhlanje. Uninzi lweefowuni eziphathwayo zakuqala zasebenzisa olu hlobo lwesikrini, esiwela phantsi kwenqanaba le-matrix yamachaphaza kwaye igxininisa ukusebenza kwepixel kunye nombala. Ubunzulu bombala ngundoqo wokuvavanya umgangatho womboniso, kunye nemigangatho eqhelekileyo equka imibala engama-256, imibala engama-4096, imibala engama-64K (65,536), kwaye nangaphezulu njengemibala engama-260K. Isiqulatho sokubonisa ngokuqhelekileyo sahlulahlulwe ngokweendidi ezintathu: isicatshulwa esicacileyo, imifanekiso elula (efana nee-icon okanye iigraphics zekhathuni), kunye nemifanekiso esemgangathweni weefoto. Abasebenzisi abaneemfuno eziphezulu zomgangatho womfanekiso bakhetha i-64K okanye ubunzulu bombala obuphezulu.
Isikrini se-LED
Izikrini ze-LED zithe ngqo-zibandakanya inani elikhulu lezibane ze-LED ezenza ipaneli yokubonisa, esetyenziswa ngokuqhelekileyo kwiibhodi zebhodi zangaphandle kunye neziboniso zolwazi.
OLED
Izikrini ze-OLED zisebenzisa itekhnoloji ye-pixel yokuzikhupha ukuvelisa imifanekiso. Ngokwemigaqo yokukhanyisa, i-OLED iphezulu kune-LCD. Ukongeza, izikrini ze-OLED zinokwenziwa zincinci, ezinceda ukunciphisa ubukhulu bezixhobo.
Ngokubanzi, iziboniso zekristale zolwelo zinokuhlelwa ngokubanzi zibe ziindidi ezimbini eziphambili: i-LCD kunye ne-OLED. Ezi ntlobo zimbini zahluke kakhulu kwiindlela zabo zokukhanyisa: I-LCDs ixhomekeke ekukhanyeni kwangaphandle, ngelixa ii-OLED zizimele. Ngokusekwe kwiindlela zetekhnoloji zangoku, zombini ezi ndidi zinokuthi ziqhubeke ziphila kunye ukuhlangabezana neemfuno ezahlukeneyo zabasebenzisi bokusebenza kombala kunye neemeko zosetyenziso.
