Ngokufika kwamathelevishini, izimpilo zabantu ziye zashintsha ngokuphawulekayo, basebenzise isikhathi esengeziwe ekhaya, emndenini womndeni. Kuze kube yilolu suku, i-TV enhle yiyo, mhlawumbe, isihloko esiyinhloko ekhaya. Kuhle ukubuka i-movie yakho oyithandayo, uchungechunge, izindaba noma umcimbi wezemidlalo ekupheleni kosuku. Ngesikhathi abantu bejabule ngeTVs elula, ama-TV e-LCD asetshenziswa kabanzi manje. Kodwa ungakhetha kanjani i-LCD TV efanele? Yiziphi izici zobuchwepheshe ze-TV ezilungile kuwe? Ungenzi kanjani iphutha lapho uthenga? Ake sibuke ndawonye.
Ngakho, wanquma ukuthenga i-LCD TV. Nazi imithetho embalwa elula.
Ngokungangabazeki, into yokuqala ethatha umbono wethu nge-TV ubukhulu bayo. Ngokuqondile, i-diagonal. Yiqiniso nakakhulu i-TV, ingcono. Kodwa lokhu akunjalo ngaso sonke isikhathi. Ibanga ukusuka ku-TV kuya endaweni ohlala ngayo lapho ubukela kubalulekile. Abantu abaningi abazi ukuthi ukukhudlwana kwe-diagonal, ibanga elingaphezulu kwefafa. Ibanga elingcono liyizikhathi ezingu-3-4 ngaphezulu kune-diagonal ye-TV. Lokhu kuzohlinzeka ngenduduzo engcono kakhulu.
Ipharamitha elandelayo okufanele uyiqaphele isinqumo. Leli xabiso livezwe ngamaphikseli. I-pixel iyinhlangano engaphansi yezithombe zobukiso be-TV. Iqukethe ulwazi mayelana nokuboniswa kwemibala ebomvu, eluhlaza neluhlaza okwesibhakabhaka. Amaphikseli amaningi akha isithombe. Ngakho-ke, isinqumo esiphezulu (amaphikseli amaningi), ngcono isithombe esithunyelwe. Kubalulekile ukwazi ukuthi ngokubukela ukusakazwa okuvamile kwethelevishini, ukuxazulula okungu-800x600 kuzokwanela (kusukela eRussia imibukiso ye-TV isakazwa ngokwemigomo). Nokho, ukubuka ama-DVD ama-movie, isinqumo kufanele sibe ngangokunokwenzeka ngangokunokwenzeka. Okubaluleke kunazo zonke yindlela yokwenza ithelevishini yedijithali, kuye isinqumo esihle kunazo zonke ngama-pixels angu-1920x1080.
Isikhathi sokuphendula se-TV yisisindo sokushintsha phakathi komnyama nomhlophe. Okufutshane isikhathi sokuphendula, kungcono ukunikeza umbala, futhi isithombe esisodwa ngeke siphumelele. Kungcono uma isikhathi sokuphendula singadluli ama-millisecond ayi-8 (ms).
Umbala omkhulu wombala we-LCD TV ukukhanya nokuphambene. Ukuqhathanisa ukulinganisa kwezingxenye ezilula kunazo zonke ezitholile zesithombe, kusiza ukuveza ukujula kombala. Isilinganiso sokuphambana singaba ngu-600: 1, 800: 1, 1000: 1. Ukuphakama kwesilinganiso, kungcono. Ukukhanya kubalulekile lapho ubukela i-TV ngezimo ezahlukene zokukhanyisa, isb. ngesikhathi sokukhanya nesimnyama sosuku. Uma ukukhanya kunganele, amehlo akho azokhathala kakhulu, futhi ngeke uthole injabulo ekubukeni. Ukukhanya kwe-450 cd / m2 kuthathwa njengokujwayelekile. I-TV enjalo iyoba mnandi ukubheka kokubili kokukhanya kwelanga nokukhanya okufakelwayo, ngesikhathi esifanayo njengoba ukudluliswa kombala kuzohlala kuphelele ngokwanele. Ezinye izinhlobo zanamuhla zama-TV e-LCD zinenzwa eyakhelwe ngaphakathi eguqulela ngokuzenzakalelayo ukukhanya.
Cishe uqaphele ukuthi uma ubuka i-LCD TV ngama-angles ahlukene (isibonelo, kusukela ohlangothini, hhayi isikhungo), khona-ke isithombe siphutha. Leli nani libizwa nge-angle yokubuka. Kukhululekile ukubuka i-TV nge-angle yokubuka eduze kwama-degrees angu-180 (177-179), le mfuneko ihlangatshezwa yizibonelo eziningi zanamuhla. I-TV yokuqala ye-LCD yayine-angle yokubuka kakhulu encane, kodwa ukuqhubeka, njengoba uyazi, akumeli.
Ukudluliswa komsindo kubalulekile. Isici esiyinhloko somsindo ubukhulu bayo, hhayi amandla, njengoba abantu abaningi becabanga. Ubukhulu bulinganiselwa kuma-decibel (dB). Ukuphakama okukhulu, ngokuzwakalayo umsindo weTV udlalwa. Amandla, njengoba kulinganiswa ku-Watts, ayithinta ikhwalithi yomsindo hhayi ngokuphawulekayo. Ngokujwayelekile, abakhiqizi ebhokisini le-TV bhala amandla we-watts angu-100, kodwa ngokuvumelana nekhwalithi ezwakalayo, awuqondi ukuthi yiziphi izici zamandla, unesistimu yesiphakamisi se-TV. Ukunakwa okuningi kunakhokhwa ukuqina.
Amagama ambalwa mayelana "nokuphuma" kanye "nokungena". Zivame ukutholakala ngemuva kwe-TV. Zonke izinhlobo zanamuhla zinezikebhe ezanele zokuxhuma isidlali se-DVD, ikhamera namanye amadivaysi. Yebo, uma i-TV inesithotho se-USB, ungakwazi ukubuka izithombe zakho ozithandayo kusukela kusikrini se-TV noma ulalele izingoma zakho ozithandayo ngokuxhuma ikhamera yakho noma i-MP3 player.
Kuhlelo lokuklama nombala we-TV encane, cishe akufanelekile ukukhuluma ngakho, ngoba zingahluka kakhulu. Lokhu kakade kuyindaba yokunambitha.
Ngakho sibuyekeze izici ezibaluleke kakhulu zama-TV e-LCD. Ukuzikhethela kungokwakho! Ukubuka okujabulisayo!
