Tau qhov twg los: projection age
Cov chaw taws teeb tswj, ua ib qho khoom siv ntawm lub koob yees duab sablaj, tau siv ntau zaus.Yog li dab tsi yog hom kev tswj chaw taws teeb ntawm lub khw?Tsuas yog los ntawm kev nkag siab cov hom no tuaj yeem ua tau zoo dua qhov tshuaj ntsuam uas cov chaw taws teeb tswj tau zoo dua rau peb.Feem ntau hais lus, cov chaw taws teeb tswj hauv kev ua lag luam tau muab faib ua peb pawg hauv qab no raws li kev faib cov teeb liab:
Thawj qeb: infrared chaw taws teeb tswj
Qhov zoo: lub hauv paus ntsiab lus tseem ceeb ntawm kev tswj chaw taws teeb no yog tswj cov khoom siv los ntawm infrared tsis pom lub teeb.Tom qab ntawd cov kab hluav taws xob infrared hloov mus rau hauv cov teeb liab digital uas tuaj yeem lees paub los ntawm cov khoom siv tswj.Hom kev tswj chaw taws teeb no tuaj yeem tswj tau nyob deb ntawm qhov ntev.
Qhov tsis zoo: txawm li cas los xij, vim muaj kev txwv ntawm infrared nws tus kheej, infrared chaw taws teeb tswj tsis tuaj yeem hla dhau los ntawm kev cuam tshuam lossis tswj cov khoom siv los ntawm lub kaum sab xis loj, thiab muaj peev xwm tiv thaiv kev cuam tshuam tsis zoo.
Qhov thib ob qeb: 2.4GHz wireless chaw taws teeb tswj
Qhov zoo: nrog kev txhim kho me ntsis ntawm cov chaw taws teeb wireless hauv cov chaw taws teeb tswj, 2.4G cov chaw taws teeb tswj cov teeb liab kis tau tus mob tuaj yeem daws qhov tsis zoo ntawm infrared chaw taws teeb tswj thiab pab kom koj tswj tau lub TV los ntawm txhua lub kaum sab xis hauv tsev.Thiab nws yog 360 degree kev ua haujlwm tsis muaj lub kaum sab xis tuag.Lub omni-directional peb-dimensional kev pab them nqi yog qhov zoo ntawm 2.4G chaw taws teeb tswj, thiab nws kuj yog hom zoo tshaj plaws ntawm cov chaw taws teeb tswj tam sim no.
Qhov tsis zoo: tus nqi ntawm 2.4G yog siab dhau.Cov khoom siv hluav taws xob feem ntau yog muag rau txhua lub nyiaj.Rau tib 11 qhov tseem ceeb ntawm cov chaw taws teeb tswj, tus nqi tsim khoom ntawm 2.4G chaw taws teeb tswj yog ob zaug ntawm infrared chaw taws teeb tswj.Yog li ntawd, hom kev tswj chaw taws teeb no feem ntau tsuas yog nyob hauv txoj haujlwm tseem ceeb hauv kev ua lag luam high-end.
Pawg thib peb: Bluetooth tswj chaw taws teeb
Qhov zoo: qhov kom zoo dua ntawm Bluetooth tswj chaw taws teeb yog tias nws tuaj yeem ua tiav qhov kev ywj pheej tag nrho cov teeb liab kis tau tus mob los ntawm kev ua ke nrog cov khoom siv.Xws li cov kab txuas txuas tuaj yeem zam qhov cuam tshuam ntawm cov teeb liab wireless ntawm cov khoom sib txawv, tab sis nws tsuas yog ib qho ntxiv rau 2.4GHz thev naus laus zis.Hauv lwm lo lus, nws ua tiav cov txiaj ntsig zoo tshaj plaws thiab ua lub luag haujlwm ntawm kev tiv thaiv ob lub teeb liab sib kis.
Qhov tsis zoo: raws li kev siv tam sim no muaj kev txhawj xeeb, Bluetooth chaw taws teeb tswj kuj muaj qee qhov tsis xws.Piv txwv li, thaum peb thawj zaug siv hom kev tswj chaw taws teeb, peb yuav tsum tau manually ua ke cov chaw taws teeb tswj nrog lub cuab yeej.Kev ua haujlwm ntawm lub cuab yeej yuav ncua sijhawm, thiab tom qab ntawd peb yuav tsum rov kho nws.Thiab tus nqi yog siab.Cov no yog cov teeb meem uas Bluetooth xav tau los daws.
