Niaj hnub nim no cov tib neeg tab tom nrhiav kev lom zem. Txawm hais tias nws yog ntsuj plig los yog khoom siv, TV, khoos phis tawj thiab lwm yam khoom siv tsis muaj txiaj ntsig yog cov neeg muaj nuj nqis. Cov khoom uas dazzling ntawm lub lag luam yog feem ntau ruam tag, xws li cov LCD thiab LED. Qhov txawv ntawm lawv yog cov ruam dhau. Niaj hnub no, tus sau piav qhia rau sawv daws qhov txawv ntawm lcd thiab coj thiab lawv cov yam ntxwv zoo.
Tus ntawm LCD thiab LED
LCD yog ib lub npe luv rau cov kua Crystal Display. Nws cov qauv yog tsuas yog muab cov kua kua nplaum nyob rau hauv ob lub qhov muag ua kom zoo nkauj. Muaj ntau ntau txoj kab thiab ntsug me me nyob hauv nruab nrab ntawm qhov no thaum uas tig mus ob lub iav, thiab cov pas nrig siv tau los ntawm lub zog los yog tsis. Cov lwg me ntsis hloov cov kev coj thiab ua kom lub teeb ci tuaj tsim duab.
LED yog lub npe ntawm lub teeb-emitting diode. Nws txoj haujlwm ua haujlwm yog hais tias nyob hauv PN txoj haujlwm ntawm qee cov ntaub ntawv semiconductor, feem ntau cov neeg tsav tsheb thiab feem ntau cov neeg ua haujlwm sib tw yuav tso tawm ntau zog hauv daim ntawv ntawm lub teeb. Lub zog hluav taws xob ncaj qha hloov mus rau hauv lub teeb zog; PN hlws tsev ntxiv ib qho rov qab muaj zog, thiab cov neeg muaj hnub nyoog tsawg yog nyuaj rau hno, thiab tsis txhob tso lub teeb. No hom kab xev uas siv lub ntsiab cai ntawm kev txhaj tshuaj rau electroluminescence hu ua light-emitting diode, uas yog li cas peb nquag hu LED.
Xaus: Qhov sib txawv loj ntawm LCD thiab LED lus dag hauv daim ntawv thov ntawm ob qho yeeb yam sib txawv. Lub LCD yog ib qho screen zaub tsim ntawm kua kua, thiab LED yog ib qho zaub screen ntawm lub teeb-emitting diodes; tag nrho cov loj sib txawv tseem muab tau los ntawm no. Tuaj tawm thiab sojntsuam.
Qhov txawv ntawm LCD thiab LED
Ua ntej tshaj plaws, qhov kev pom ntawm lub teeb pom kev zoo ntawm ib lub ntsiab yog 1000 tauj LCD LCD npo, nws txoj kev ci ntsa iab tseem zoo dua li LCD LCD npo, LED cov vijtsam tso tawm kuj tuaj yeem nyob rau ntawm lub qhov muag, thiab hloov Tsawg siab ntawm rho 40 degrees.
Qhov thib ob, kev siv fais fab, kev siv fais fab yog kev txhawj xeeb tshaj ntawm tib neeg, LED fais fab siv piv nrog LCD, qhov piv ntawm 10: 1, nyob rau hauv no hais txog, LED muaj zoo dua.
Qhov thib peb, qhov pom lub kaum sab xis, Lub rooj sab laj LCD siab yog qhov loj heev, qhov no yog ib tus neeg mob lub cev heev, tsuas yog qhov txawv txav me ntsis xwb, koj tuaj yeem pom thawj xim, thiab tsis tuaj yeem pom txhua yam; LED Muab lub kaum sab laj pom txog li ntawm 160 °.
Qeb plaub, lub zog tshiab, kev siv hluav taws xob hluav taws xob lub zog mus rau hauv lub teeb zog, siv lub hau kev txhaj tshuaj, yog li nws siab zog dua, ces zoo dua hauv kev ua yeeb yaj kiab.
Tsib, qhov sib txawv ntawm qhov sib piv, tus qauv sib npaug loj hauv LCD tam uas tam sim no yog 350: 1, tab sis feem ntau, nws tsis tuaj yeem ua tau ntau yam kev xav tau, tab sis LED tso peev xwm ua tau siab dua thiab siv ntau dua.
Rau, qhov pom ntawm LED raws li kev siv ntawm lub teeb-emitting diodes, LCD tus txheeb ze, cov zaub ua ib thinner.
Xya, cov khoom siv, LED zaub daim ntawv thov khwv tau zoo dua li cov duab LCD, nws tuaj yeem tso ntau hom ntawv nyeem, zauv, xim cov duab thiab cov lus qhia txog animation, tab sis tseem tuaj yeem ua si TV, yees duab, VCD, DVD thiab lwm yam xim video , ntau qhov tseem ceeb Nws yog ua tau los siv ntau cov ntxaij vab tshaus rau online tshaj tawm.
Yim, lub neej kev ua haujlwm, LED cov zaub yuav tuaj yeem txhawb txog 100,000 xuab moos, nyob rau hauv ib txwm muaj tshwm sim, siv tau rau xyoo lawm, tab sis LCD tsawg dua.
Cuaj, xim, LED npo tshaj li cov xim xauv npo yog qhov tseeb dua, vim LED TV lub xim gamut ntau ntau dua li cov LCD.
