Dab tsi yog 4 Hom Kev Pom Zoo?

Taw qhia

Cov zaub yog ib qho cuab yeej siv los qhia cov ntaub ntawv rau tus neeg siv hauv hom kev pom. Muaj ntau hom kev nthuav qhia muaj, thiab txhua hom muaj nws cov yam ntxwv tshwj xeeb thiab tsim. Hauv tsab xov xwm no, peb yuav mus hla plaub hom kev qhia uas feem ntau siv hauv ntiaj teb niaj hnub no.

Hom 1: Cathode Ray Tube (CRT)

CRT zaub yog ib qho ntawm cov laus tshaj plaws thiab feem ntau hom kev qhia. Cov zaub no siv lub tshuab nqus tsev vacuum nrog rab phom electron uas tso tawm ib lub teeb hluav taws xob mus rau lub vijtsam phosphor-coated, uas tsim cov duab. ** CRT zaub yog qhov loj thiab hnyav vim lub tshuab nqus tsev nqus tsev vacuum, ua rau nws tsis tshua muaj nyob rau hauv cov khoom siv niaj hnub no. Txawm li cas los xij, lawv ib zaug yog qhov tseem ceeb ntawm cov cuab yeej siv hauv TV thiab computer saib.

** Hom 2: Liquid Crystal Display (LCD)

LCD zaub tau siv dav hauv cov khoom siv niaj hnub no. Cov lus qhia no siv txheej txheej ntawm cov kua siv lead ua kua molecules ntawm ob nplooj ntawv ntawm cov khoom siv polarizing los tsim cov duab digital. ** Lub LCD zaub yog qhov nyias nyias thiab sib piv rau CRT zaub, ua rau nws zoo meej rau cov khoom siv txawb xws li smartphones thiab ntsiav tshuaj.

** Hom 3: Lub teeb Emitting Diode (LED)

LED zaub yog ib hom LCD zaub uas siv cov array ntawm lub teeb-emitting diodes (LEDs) rau backlight cov zaub, tso cai rau cov duab ci dua thiab zoo sib xws. ** Cov zaub no tau dhau los ua neeg nyiam vim nws lub zog ua haujlwm thiab lub neej ntev, ua rau nws zoo tagnrho rau sab nraum zoov kos npe thiab cov npo loj.

** Hom 4: Organic Light Emitting Diode (OLED)

OLED zaub yog ib yam tshiab ntawm cov cuab yeej siv tshuab uas siv cov khoom siv organic los tsim lub teeb. Cov zaub no siv cov array ntawm cov organic tebchaw uas emit lub teeb thaum muaj hluav taws xob tam sim no dhau los ntawm lawv. ** Lub OLED zaub yog nyias, hloov tau, thiab lub teeb yuag, ua rau nws zoo tagnrho rau siv hauv cov khoom siv txawb xws li smartphones thiab smartwatches.

** Lus xaus

Hauv kev xaus, plaub hom kev qhia yooj yim yog Cathode Ray Tube (CRT), Liquid Crystal Display (LCD), Lub Teeb Emitting Diode (LED), thiab Organic Light Emitting Diode (OLED). Txhua hom zaub muaj nws cov yam ntxwv tshwj xeeb thiab tsim, ua rau lawv zoo tagnrho rau cov ntawv thov tshwj xeeb. Nrog rau kev nce qib hauv kev siv thev naus laus zis, peb tuaj yeem cia siab tias yuav muaj kev txhim kho ntxiv thiab kev tsim kho tshiab hauv kev siv thev naus laus zis yav tom ntej.
