Lub TV teeb yog ib qho khoom siv uas xa cov duab txav mus los thiab cov cim suab siv hluav taws xob raws li kev pom ib ntus ntawm tib neeg lub qhov muag thiab pom kev puas siab puas ntsws, piv txwv li, LED TV receiver. Nws kuj yog ib qho cuab yeej tseem ceeb rau kev tshaj tawm thiab kev sib txuas lus video. Lub hauv paus system ntawm lub TV teeb muaj 3 qhov chaw: lub koob yees duab, kis tau tus mob, thiab tso saib.
Lub TV teeb yog tsuas yog tsim los ntawm lub taub hau siab, tus khub lub taub hau, tus khub channel, pej xeem channel, synchronous scan channel, xim tswj cov zaub thiab lub zog, thiab lwm yam. Nws txoj haujlwm ua haujlwm yog raws li hauv qab no.
Lub teeb liab tau txais los ntawm lub kav hlau txais xov, los ntawm lub taub hau siab kom xaiv lub siab-zaus LED TV teeb liab, thiab amplify qhov kev ua, thiab ces xa tawm ib tug ruaj IF LED TV teeb liab.
Cov channel feem ntau yog tsim los ntawm IF amplifier, video detector, video amplifier, thiab duab tube. Lub IF amplifier amplifies IF teeb liab los ntawm HF lub taub hau kom txaus amplitude pom cov nthwv dej los ntawm tus yees duab ntes, tshem tawm IF cov cab kuj, rov kho cov duab teeb liab, thiab hloov qhov thib ob ntawm lub suab IF teeb liab. Duab teeb liab los ntawm video amplification yog xa mus rau lub cathode ntawm emitting electrons nyob rau hauv daim duab raj, los tswj qhov tseem ceeb ntawm emitting electron beam ntawm daim duab raj. Lub vijtsam fluorescent tuaj yeem tshwm rau ntawm daim duab. Tias yog vim li cas koj tuaj yeem pom xim thiab hnov suab ntawm Apple TV , YouTube tv , thiab Bridgeton.
Tus qauv ntawm lub TV teeb
1. Lub tshuab tag nrho ua ntej thiab tom qab cov chaw taws teeb tswjAs LED TV tau teeb tsa, thiab tawm, xaiv qhov kev zov me nyuam, hloov ntim, thiab ntau qhov chaw ua haujlwm muaj los ua kom tiav cov chaw taws teeb tswj, thiab yog li cov chaw taws teeb tswj tau dhau los ua ib feem tseem ceeb ntawm TV peripherals. Cov yuam sij tswj ntawm lub vaj huam sib luag pem hauv ntej ntawm lub TV teeb tau txais tsawg thiab tsawg. Tsuas yog lub hwj chim hloov yog qhov tseem ceeb, vim tsuas yog thaum lub hwj chim hloov. Lub TV teeb tuaj yeem nkag mus rau hauv lub xeev standby, thiab cov chaw taws teeb tswj tuaj yeem muaj kev tswj hwm ntawm lub TV teeb. Thaum ua haujlwm ntawm cov chaw taws teeb tswj, cov chaw taws teeb tswj yuav tsum tau ua raws li 'infrared txais qhov rais' nyob rau pem hauv ntej vaj huam sib luag, thiab ntau yam ntaub ntawv tswj tau xa mus rau TV los ntawm lub teeb infrared. Muaj ib txoj kab hluav taws xob, tau txais cov kav hlau txais xov qhia qhov, thiab video thiab audio input davhlau ya nyob twg nyob rau sab nraum qab ntawm lub chassis.
2. Cov khoom tseem ceeb ntawm lub TV teeb
Txawm xim los yog xim dub thiab dawb LED TV teeb, nws chassis feem ntau yog tsim los ntawm peb qhov chaw: lub vaj huam sib luag pem hauv ntej (pem hauv ntej ncej), ncej, thiab sab nraub qaum. Hauv kev ua haujlwm tu tsis tu ncua, lub vaj huam sib luag pem hauv ntej thiab ncej tsis tas yuav tsum tau disassembled. Tsuas yog lub nraub qaum tuaj yeem raug tshem tawm rau kev saib xyuas dav dav, yog li muaj ib feem ntawm lub TV pem hauv ntej vaj huam sib luag thiab thav duab rau hauv tag nrho. Tshem lub hau rov qab kom pom qhov tseem ceeb ntawm lub TV teeb. Lawv tuaj yeem muab faib ua peb qhov loj: sab nraub qaum ntawm lub chassis, lub vaj huam sib luag pem hauv ntej, thav duab thiab duab raj, thiab lwm yam, lub ntsiab luam ntawv hauv paus phaj (core), thiab ntau yam.
Feilong vam thiab cia siab tias s yuav txhim kho ua ke nrog peb cov phooj ywg thoob plaws ntiaj teb hauv lub siab zoo. Yog tias koj xav paub ntau ntxiv txog peb cov khoom, thov hu rau peb kom paub ntau ntxiv txog peb cov khoom. Peb tos ntsoov rau koj hu.
