Isethi ye-TV iyisisetshenziswa esidlulisa izithombe ezinyakazayo namasignali alalelwayo kusetshenziswa ubuchwepheshe be-elekthronikhi ngokuya ngezici zesikhashana ezibonakalayo zeso lomuntu kanye nesayikholoji yokubuka, okungukuthi, Isitholi sikamabonakude se-LED . Kuphinde kube yithuluzi elibalulekile lokusakaza kanye nokuxhumana ngevidiyo. Uhlelo oluyisisekelo lwesethi kamabonakude luqukethe izingxenye ezi-3: ikhamera, ukudlulisa, nesibonisi.
Isethi ye -TV yakhiwe ngokuyinhloko ikhanda lemvamisa ephezulu, inhloko yomsindo engumngane, isiteshi esiwumngane, isiteshi somphakathi, isiteshi sokuskena esivumelanayo, isibonisi sokulawula umbala kanye nokunikezwa kwamandla, nezinye izingxenye. Umgomo wayo wokusebenza umi kanje.
Isignali etholwe ku-antenna, ngekhanda lefrikhwensi ephezulu ukuze ukhethe i-high-frequency Isignali ye-TV ye-LED , futhi ikhulise ukucutshungulwa, bese ithumela i-IF ehleliwe Isignali ye-TV ye-LED .
Isiteshi esivamile sakhiwe isikhulisi se-IF, isithwebuli sevidiyo, isikhulisi sevidiyo, neshubhu yezithombe. Isikhulisi se-IF sikhulisa isignali ye-IF kusukela ekhanda le-HF kuya ku-amplitude eyanele ithola igagasi ngomtshina wevidiyo, isuse inkampani yenethiwekhi ye-IF, ibuyisele isignali yesithombe, futhi iguqule ucezu lwesibili lwesignali ye-IF yomsindo. Isignali yesithombe ngokukhulisa ividiyo ithunyelwa ku-cathode yama-electron akhiphayo kushubhu yesithombe, ukulawula ukugcizelelwa kwe-electron beam ephumayo yeshubhu lesithombe. Isikrini se-fluorescent singaboniswa esithombeni. Yingakho ungabona umbala futhi uzwe umsindo ku- Apple TV , YouTube tv , kanye ne-Bridgeton.
Isakhiwo sesethi ye-TV
1. Wonke umshini ngaphambi nangemuva kwesilawulikude Njengo I-LED Television ivuliwe futhi ivaliwe, ukukhethwa kohlelo, ukulungiswa kwevolumu, futhi izilungiselelo ezihlukahlukene zokusebenza ziyatholakala ukuze kuqedelwe isilawuli kude, futhi ngaleyo ndlela isilawuli kude sesiyingxenye ebalulekile yamaperipheral e -TV . Okhiye bokulawula kuphaneli yangaphambili yesethi ye -TV baya ngokuya bencipha. Ukushintsha kwamandla kuphela kubalulekile, ngoba kuphela uma inkinobho yamandla ivuliwe. Isethi ye-TV ingangena esimweni sokulinda, futhi isilawuli kude singaba nomthelela olawulayo kusethi ye-TV . Uma usebenzisa isilawuli kude, isilawuli kude kufanele siqondaniswe 'newindi lokwamukela ngeso lefoni' kuphaneli yangaphambili, futhi ulwazi lokulawula oluhlukahlukene ludluliselwa ku- TV ngokukhanya kwe-infrared. Kukhona intambo yamandla, imbobo yesingeniso ye-antenna, kanye netheminali yokufaka ividiyo nomsindo esembozweni esingemuva se- chassis.
2. Izingxenye eziyinhloko -TV zesethi ye
Noma ngabe umbala noma omnyama nomhlophe I-LED Television sets, i-chassis yayo ngokuvamile yakhiwe izingxenye ezintathu: iphaneli yangaphambili (uhlaka lwangaphambili), uhlaka, nekhava yangemuva. Emsebenzini wokulungisa njalo, iphaneli yangaphambili kanye nohlaka akudingeki ukuba kuhlakazwe. Ikhava yangemuva kuphela engasuswa ukuze kwenziwe imisebenzi yokulungisa okuvamile, ngakho-ke kukhona ingxenye yephaneli ye -TV engaphambili kanye nefreyimu ibe iyonke. Susa ikhava yangemuva ukuze ubone izingxenye eziyinhloko zesethi ye -TV . Zingahlukaniswa zibe izingxenye ezintathu ezinkulu: isembozo sangemuva se-chassis, iphaneli yangaphambili, ifreyimu neshubhu lesithombe, njll., i-main base plate (core), kanye nezingxenye ezihlukahlukene.
U-Feilong unethemba lobuqotho s lokuthuthuka ndawonye nabangane bethu emhlabeni wonke ngomoya omuhle. Uma ufisa ukwazi okwengeziwe ngemikhiqizo yethu, sicela ukhululeke ukusishayela ukuze uthole ulwazi olwengeziwe lomkhiqizo. Sibheke ngabomvu ocingweni lwakho.
