Txhais ntawm LCD thiab Nws Yog Txawv Ntau Tshaj Lawm Tshaj Lij
Luv luv LCD, kua siv lead ua kua yog lub txaj, cov ntaub ntawv nyias nyias uas tau hloov cov laus CRT zaub. LCD muab cov duab zoo dua qub thiab kev pabcuam rau cov haujlwm loj.
Feem ntau, LCD hais txog hom kev saib xyuas siv tshuab LCD, tab sis kuj tseem ceeb qhia txog xws li hauv cov laptops, tshuab xam zauv, digital koob yees duab, digital watches, thiab lwm yam khoom siv sib xws.
Lus Cim: Muaj kuj yog ib qho FTP txib uas siv cov ntawv "LCD." Yog tias qhov ntawd yog dab tsi tom qab, koj tuaj yeem nyeem ntxiv txog nws ntawm no, tab sis nws tsis muaj dab tsi ua rau cov computers lossis TV qhia.
Yuav Ua Li Cas LCD Ntxaij Ua Haujlwm?
Raws li "kua siv lead ua kua" yuav qhia, LCD cov ntxaij lim dej siv kua nplaum ua cov pixels rau thiab tawm kom pom tseeb xim. Cov kua dej muaj xws li sib xyaw ntawm cov khoom thiab kua, qhov twg cov hluav taws xob tam sim no tuaj yeem siv los hloov lawv lub xeev kom tau ib qho kev tshwm sim.
Cov kua crystals no yuav xav txog xws li lub qhov rai shutter. Thaum lub shutter qhib, lub teeb tau yooj yim dhau mus rau hauv chav. Nrog cov ntxaij vab tshaus LCD, thaum cov iav ci ntsa iab rau hauv ib txoj hauv kev tshwj xeeb, lawv tsis pub kom lub teeb ntawd dhau los.
Nws yog sab nraum qab ntawm ib lub vijtsam sablaj (LCD screen) uas yog lub luag haujlwm ntawm lub teeb ci los ntawm kev tshuaj ntsuam. Pem hauv ntej ntawm lub teeb yog ib qho screen ua los ntawm pixels uas muaj xim liab, xiav, lossis ntsuab. Cov kua nplaum ua kua yog lub luag hauj lwm rau lub tshuab hluav taws xob xa los sis tua tawm hauv kom paub tseeb tias muaj xim zoo li cas los yog khaws cov pixel dub.
Qhov no txhais tau tias cov ntxaij lim dej tseem ua haujlwm los ntawm kev thaiv cov teeb ntawm lub teeb ntawm lub vev xaib es tsis txhob tsim teeb rau lawv tus kheej xws li CRT cov ntxaij ua haujlwm. Qhov no tso cai rau cov neeg saib xyuas LCD thiab TVs siv tsawg dua cov hwj huam tshaj li CRT.
LCD vs LED: Dab tsi & # 39; s qhov txawv?
LED stands rau teeb emitting diode . Txawm hais tias nws muaj ib lub npe sib txawv tshaj li qhov siv lead ua kua , nws tsis yog dab tsi txawv kiag li, tiam sis nws tsuas yog ib qho txawv ntawm LCD npo xwb.
Qhov loj qhov txawv ntawm LCD thiab LED cov ntxaij vab yog li cas lawv muab backlighting. Cov teeb pom kev zoo hais txog qhov kev ntsuam xyuas lub teeb ntxig li cas los yog tawm, tej yam uas tseem ceeb heev rau kev muab duab zoo, tshwj xeeb ntawm cov xim dub thiab xim ntawm qhov screen.
Ib txwm siv LCD npo siv lub teeb cathode fluorescent teeb (CCFL) rau kev siv rau kev lag luam, thaum cov ntxaij vab tshaus coj siv ntau dua thiab lub teeb me ntsis emitting diodes (LED's). Qhov txawv ntawm ob yog tias CCFL-backlit LCD's tsis tuaj yeem thaiv tag nrho cov xim dub, hauv qhov xwm txheej zoo li ib tug dub ntawm cov dawb nyob rau hauv ib qho yeeb yaj duab yuav tsis tshwm ntsej muag heev tom qab tag nrho, thaum LED backlit LCD's localize lub blackness rau ib tug ntau ntxaum sib piv.
Yog tias koj muaj sij hawm nyuaj rau qhov kev nkag siab qhov no, cia li xav txog qhov tsaus ntuj yeeb yam scene ua piv txwv. Nyob rau hauv lub scene yog ib tug tiag tiag maub, dub chav tsev nrog ib tug kaw qhov rooj uas lub hom phiaj rau ib co teeb los ntawm lub hauv qab tawg. Ib qho screen LCD nrog LED backlighting yuav rub nws zoo dua CCFL backlighting cov ntxaij lim dej vim hais tias yav dhau los tuaj yeem xim rau lub qhov rooj ntawm qhov rooj, cia tag nrho cov seem ntawm lub vijtsam kom nyob twj ywm tiag tiag.
Lus Cim: Tsis yog txhua qhov thiab txhua qhov pom ntawm LED yog qhov peev xwm ntawm qhov ntsuas lub npov zos li koj tsuas yog nyeem. Nws yog feem ntau full-array TV's (tiv thaiv-ntug lit) uas txhawb lub zos dimming.
Lus Qhia Ntxiv rau LCD
Nws tseem ceeb heev uas yuav tsum tau saib xyuas tshwj xeeb thaum tu cov ntxaij lim dej, seb lawv puas yog TVs, smartphones, computer monitors, thiab lwm yam.
Tsis zoo li CRT saib thiab TVs, cov ntxaij vab tshaus LCD tsis muaj qhov hloov tshiab . Tej zaum koj yuav tsum hloov qhov ntsuas qhov tshiab qhov chaw tshiab ntawm CRT yog tias qhov muag tsis pom yog qhov teeb meem, tab sis nws tsis tsim nyog rau cov koob yees duab tshiab.
Feem ntau cov neeg saib hauv tshuab hlwb hlau muaj kev txuas rau HDMI thiab DVI cables. Ib txhia tseem txhawb VGA cables, tiam sis qhov tsawg dua. Yog tias koj lub computer daim video card tsuas yog qhov kev sib txuas VGA txuas ntxiv, nco ntsoov saib ob sab-saib tias lub LCD monitor muaj kev txuas rau nws. Koj yuav tsum tau yuav VGA mus rau HDMI los yog VGA rau DVI adapter kom ob hnub siv tau rau txhua lub tshuab.
Yog tias tsis muaj ib yam dab tsi uas qhia hauv koj lub computer saib, koj tuaj yeem khiav los ntawm cov kauj ruam hauv peb Li Cas los soj ntsuam Computer Computers uas tsis ua hauj lwm troubleshooting phau ntawv qhia seb yog vim li cas.
