Qhov zoo/qhov tsis zoo/sib txawv/daim ntawv thov scenarios ntawm LED thiab LCD cov ntxaij vab tshaus

LCD thiab LED cov ntxaij vab tshaus yog hom tshuaj ntsuam ntau tshaj plaws hauv cov khoom siv hluav taws xob xws li TVS, khoos phis tawj saib, xov tooj ntawm tes, ntsiav tshuaj, thiab lwm yam, LCD thiab LED tsuas yog ib tsab ntawv sib nrug, tab sis:

LCD yog lub npe tag nrho ntawm Liquid Crystal Display (Liquid Crystal Display), nws los ntawm cov khoom siv ua kua siv lead ua kua hloov pauv los tswj cov teeb pom kev zoo, thiaj li ua tiav cov txiaj ntsig pom, vim nws cov xim tsis tshua muaj xim kis tau tus mob thiab dav siv hauv digital. cov khoom lag luam, tab sis kuj vim nws qhov raug siab thiab kev daws teeb meem siab rau kev kho mob thiab kev lag luam aviation.

LED tag nrho lub npe Lub Teeb Emitting Diode (Lub Teeb Emitting Diode), nws yog hom tshuaj ntsuam nrov heev hauv xyoo tas los no. Nws siv lub teeb-emitting diodes kom ua tiav cov nyhuv tso saib, vim tias nws tuaj yeem muaj cov xim ntshiab thiab ci ntsa iab hauv qhov ci ntsa iab thiab ib puag ncig sab nraum zoov, thiab tsim nyog rau daim ntawv thov hauv tsheb thiab sab nraum zoov teeb pom kev zoo. 

   Ua ntej, cia peb saib qhov zoo thiab qhov tsis zoo ntawm LED thiab LCD:

1. Qhov zoo ntawm LCD npo yog raws li nram no:

A. Cov nyhuv zoo. Lub vijtsam LCD siv qhov hloov pauv ntawm cov khoom siv ua kua siv lead ua kua los tswj lub teeb xa hluav taws xob, ua rau cov duab pom meej dua, ci ntsa iab thiab raug. Tsis tas li ntawd, lub vijtsam LCD tuaj yeem tso saib cov xim tiag tiag, thiab cov nyhuv ntawm cov duab yog ntau yam ntuj tso.

B. Nws tuaj yeem txuag hluav taws xob. Piv nrog CRT cov ntxaij vab tshaus, cov ntxaij vab tshaus LCD tuaj yeem txuag tau ntau lub zog. Vim tias lawv siv cov ntaub ntawv siv lead ua kua, tsis tas yuav muaj rab phom electron ntxiv los ua kom cov pixels ntawm qhov screen. Qhov no muab cov ntxaij vab tshaus LCD muaj txiaj ntsig zoo ntawm kev siv hluav taws xob.

C. Cov zaub ceev ceev. Cov lus teb ceev ntawm lub vijtsam LCD yog ceev heev, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov duab nrawm nrawm. Tsis tas li ntawd, lub vijtsam LCD kuj tseem tuaj yeem txo qhov ci ntsa iab thiab txo qhov muag nkees.

2. Qhov tsis zoo ntawm LCD npo yog raws li nram no:

A. Lub kaum sab xis saib me me. Cov ntxaij vab tshaus LCD feem ntau muaj ntau qhov me me ntawm cov duab saib, thiab cov duab yuav plooj lossis tsis meej pem thaum koj saib ntawm sab lossis hauv qab ntawm lub vijtsam.

B. Cov xim dub tsis tob txaus. Cov xim dub tso rau ntawm cov ntxaij vab tshaus LCD tsis tob txaus vim lawv xav tau lub teeb rov qab los tso saib cov duab. Yog li ntawd, thaum muaj xim dub tshwm, lub keeb kwm yav dhau grey lossis dawb yuav tshwm sim.

3. Qhov zoo ntawm LED screen yog raws li nram no:

A. Muaj peev xwm ua kom pom cov duab zoo. LED npo muaj cov xim ci, siab ci thiab zoo sib xws. Lawv tuaj yeem ua kom pom cov duab zoo dua, ci dua hauv qhov chaw sab nraum zoov.

B. Ntau zog txuag. LED cov ntxaij vab tshaus siv lub teeb-emitting diodes kom ua tiav cov nyhuv tso saib, uas tuaj yeem txuag hluav taws xob ntau dua li niaj hnub TV thiab computer saib.

C. Haum rau ib puag ncig sab nraum zoov. LED cov ntxaij vab tshaus tuaj yeem tsis tsuas yog tso saib cov duab meej, ci ntsa iab sab hauv tsev, tab sis kuj tseem pom cov duab pom tseeb thiab ci dua nyob rau hauv qhov chaw sab nraum zoov. Qhov no ua rau lawv zoo tagnrho rau sab nraum zoov billboards, concerts, kis las kis las thiab ntau dua.

4. Qhov tsis zoo ntawm LED npo yog raws li hauv qab no:

A. Tus nqi siab. Piv rau cov ntxaij vab tshaus LCD, LED cov ntxaij vab tshaus yog kim dua los tsim, uas kuj ua rau lawv kim dua. Yog li ntawd, yog tias koj xav yuav lub vijtsam LED loj, koj xav tau cov peev nyiaj txaus.

B. Grey nplai kev ua tau zoo tsis zoo li LCD. Txawm hais tias cov lus qhia LED muaj qhov zoo ntawm cov xim ci, lub teeb ci siab, thiab qhov sib txawv zoo, lawv tsis zoo li LCD cov lus hauv grey scale kev ua tau zoo. Qhov no txhais tau hais tias thaum cov duab uas tsis tshua muaj teeb pom kev zoo, tej zaum yuav muaj xim tsis sib xws lossis distorted.

      Qhov thib ob, cia peb saib qhov sib txawv ntawm LED thiab LCD hauv txoj hauv kev ua haujlwm, ci ci zog noj, xim gamut, thiab tus nqi hauv daim ntawv thov scenarios.

1. Qhov sib txawv ntawm cov qauv kev ua haujlwm

LCD yog cov cuab yeej siv thev naus laus zis uas siv cov anisotropy ntawm cov kua siv lead ua kua molecules thiab hluav taws xob teb tswj los kho lub teeb xa mus, thiaj li ua tiav cov duab pom. Nws tsuas yog muaj ob txheej txheej ntawm cov iav iav nrog kua siv lead ua molecules sandwiched ntawm lawv. Thaum energized, cov kua siv lead ua kua molecules yuav deformed, uas cuam tshuam rau lub teeb transmittance, kom cov khoom nthuav tawm cov duab. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm LCD yog zoo ib yam li lub teeb valve, yog li nws tseem hu ua lub teeb valve zaub tshuab.

Tsis zoo li LCD, LED yog cov cuab yeej siv digital uas siv cov khoom siv hluav taws xob tam sim no los tsim lub teeb ci. LEDs yog tsim los ntawm lub teeb-emitting diodes thiab sab nraud circuits. Thaum energized, tus nqi nqa khoom nyob rau hauv cov khoom siv semiconductor zoo siab, uas emits photons thiab tsim lub teeb ci. LED ua haujlwm zoo li lub nti, yog li nws tseem hu ua LED nti thev naus laus zis.

2. Qhov sib txawv ntawm qhov ci thiab kev siv zog

LEDs muaj qhov ci ntsa iab ntau dua thiab kev siv hluav taws xob qis dua, feem ntau yog vim lawv siv lub teeb-emitting diodes los tsim lub teeb ci, zam cov txheej txheem ntawm kev siv phosphors los tsim lub teeb ci hauv cov khoom siv niaj hnub. Piv rau phosphors, leds emit lub teeb zoo dua thiab muaj peev xwm ua tiav cov xim dav dua thiab ua haujlwm ntev dua. Tsis tas li ntawd, LED kuj muaj qhov zoo ntawm kev hloov kho qhov ci, los ntawm kev kho qhov siv tam sim no thiab ci ntsa iab thiab lwm yam tsis zoo, koj tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws hauv ntau zaus.

Hauv qhov sib piv, LCDS muaj qhov ci ntsa iab ntau dua thiab kev daws teeb meem siab dua, tab sis lawv lub zog siv ntau dua. LCD yuav tsum tau siv lub teeb rov qab los teeb lub vijtsam LCD, yog li nws siv ntau lub zog. Txawm hais tias LCDS tuaj yeem txo qis kev siv hluav taws xob los ntawm kev tswj lub teeb nraub qaum, qhov no feem ntau ua rau muaj teeb meem xws li qhov ci tsis sib xws.

3. Cov xim sib txawv thiab gamut

Kuj tseem muaj qee qhov sib txawv ntawm cov xim thiab gamut ntawm leds thiab LCDS. LED los ntawm kev sib xyaw ua ke ntawm RGB peb lub ntsiab xim kom ua tiav cov xim gradient thiab sib xyaw, yog li koj tuaj yeem ua tiav ntau yam xim thiab hloov xim ntau dua. LCD los ntawm lub teeb pom kev hloov pauv kom ua tiav cov xim sib txawv thiab ci ntsa iab, txawm tias nws tuaj yeem ua tiav cov xim zoo, tab sis nws tag nrho cov xim gamut me dua LED.

4. Qhov sib txawv ntawm tus nqi thiab daim ntawv thov scenarios

Kuj tseem muaj qee qhov sib txawv ntawm tus nqi thiab daim ntawv thov scenarios ntawm LED thiab LCD. Vim tias cov leds muaj qhov ci siab dua, kev pab lub neej ntev dua thiab ntau yam xim, cov leds tau siv dav hauv thaj chaw xws li sab nraum zoov, teeb pom kev zoo thiab tsheb. LCD feem ntau yog siv hauv TVS hauv tsev, lub computer saib thiab cov khoom siv sab hauv tsev hauv chaw ua haujlwm. Tsis tas li ntawd, tus nqi ntawm LCD yog tus nqi qis, yog li nws kuj tau txais ntau dua thiab nrov.

Txawm li cas los xij, hauv qee qhov kev thov tshwj xeeb, xws li kev kho mob thiab kev lag luam aviation, LCD kuj tuaj yeem ua rau nws zoo dua. Piv txwv li, hauv chav ua haujlwm, LCD yog dav siv hauv cov khoom siv kho mob xws li MRI thiab CT vim qhov xav tau ntawm cov khoom siv ua haujlwm siab thiab kev daws teeb meem siab los pab cov kws kho mob ua haujlwm phais. Tsis tas li ntawd, LCD kuj tseem tuaj yeem ua tiav cov duab muaj tseeb dua los ntawm cov kua siv lead ua 3D thev naus laus zis.

Los ntawm saum toj no peb tuaj yeem pom: LCD cov ntxaij vab tshaus thiab cov ntxaij vab tshaus LED muaj lawv tus kheej cov yam ntxwv thiab qhov zoo ntawm cov xwm txheej sib txawv. Yog tias koj xav tau tso saib cov duab zoo, koj tuaj yeem xaiv LED npo; Yog tias koj xav tau cov khoom muaj tseeb dua uas txuag lub zog, koj tuaj yeem xaiv lub vijtsam LCD. Thaum xaiv ib qho screen, koj kuj yuav tsum xav txog yam xws li pob nyiaj siv, scene, thiab lwm yam.

Nrog kev nce qib ntawm kev siv thev naus laus zis, ob hom kev tshuaj ntsuam no tseem niaj hnub hloov zuj zus thiab txhim kho, thiab yuav muaj cov ntxaij vab tshaus siab dua thiab zoo tshaj yav tom ntej. Txawm koj xaiv qhov screen twg, lawv yuav muab koj cov duab meej dua, ci dua, muaj tseeb dua thiab pom kev zoo dua.
