Peb, electromagnetic classification
01 Electromagnetic cwj mem
Raws li tus cwj mem electromagnetic, nws tuaj yeem muab faib ua tus cwj mem nquag thiab tus cwj mem passive.
(1) Active cwj mem-active electromagnetic cwj mem
Tus cwj mem nquag emissions electromagnetic signals los ntawm lub roj teeb built-in, thiab nws tuaj yeem tso tawm cov cim hluav taws xob tsis tu ncua tsis hais seb tus cwj mem hluav taws xob nyob ze ntawm lub vijtsam electromagnetic los yog tsis. Lub teeb liab electromagnetic muaj zog, cov lus teb ceev ceev, qhov loj tuaj yeem loj dua, lub zog siv hluav taws xob tsawg, thiab muaj peev xwm tiv thaiv kev cuam tshuam muaj zog dua. , Tab sis tus nqi ntawm tus cwj mem electromagnetic yog siab, thiab nws yuav tsum tau nruab ib lub roj teeb lossis them nqi. Tsuas yog cov cwj mem nquag siv tau rau qhov loj. Qhov loj ntawm tus cwj mem yog txwv los ntawm qhov loj thiab qhov hnyav ntawm lub roj teeb.
(2) Passive cwj mem-passive electromagnetic cwj mem
Passive electromagnetic muaj lub zog siv hluav taws xob siab ntsig txog kev ua haujlwm, thiab nws tsuas tuaj yeem ua rau me me, mus txog 22 ntiv tes, nrog lub kaum sab xis tsis muaj zog thiab tsuas yog ib tus cwj mem kov. Qhov zoo dua yog tias tus cwj mem hluav taws xob tsis tas yuav tsum muaj lub zog, thiab lub stylus ntawm cov khoom siv nqa tau tuaj yeem siv tau. Me me heev. Passive cwjmem xav tau cov kav hlau txais xov siab dua li cov cwj mem nquag, thiab cov kev daws teeb meem ntawm cov cwj mem nquag yog kim dua cov cwj mem passive hauv tib qhov me me. Lub passive electromagnetic cwj mem tsis nyob ze ntawm lub vijtsam electromagnetic thiab tsis tuaj yeem txais lub zog hluav taws xob. Qhov ntev ntawm qhov kev ncua deb, qhov tsis muaj zog ntawm cov teeb liab, tab sis vim nws tsis xav tau roj teeb, nws yog lub teeb thiab tsis muaj qhov yuav tsum tau rau tus cwj mem. Nws muaj qhov zoo dua rau cov cwj mem hauv qab 20 ntiv tes. Tam sim no, muaj ntau qhov me me ntawm kev ua lag luam. Xws li e-lag luam kos npe boards, pos tshuab, e-nyeem ntawv, thiab lwm yam.
02 Khoom siv
Raws li cov khoom siv, nws tuaj yeem muab faib ua pob tshab thiab opaque. Cov qub tuaj yeem siv rau cov teeb pom kev ncaj qha thiab cov teeb ci ntsa iab; tom kawg tsuas yog siv tau rau cov teeb pom kev ntawm ntug.
(1) Sab-hom backlight
Lub ntug-lit LED backlight yog npaj cov LED tuag nyob rau hauv periphery ntawm lub LCD npo, thiab ces phim lub teeb qhia phaj, thiaj li hais tias thaum lub LED backlight module emits lub teeb, lub teeb tawm ntawm ntug ntawm lub screen yog xa mus rau qhov chaw nruab nrab ntawm qhov screen los ntawm lub teeb qhia phaj. , nyob rau hauv txoj kev no, tag nrho cov nyiaj rov qab yog muaj, tso cai rau lub vijtsam LCD tso saib cov duab.
Qhov zoo: tsawg LED siv lead ua khoom siv tau, txuag nqi ntawm cov khoom siv lead ua LED; lub teeb thiab nyias lub cev
Qhov tsis zoo: qhov ci tsis sib xws, xav tau ntxiv DBEF; loj loj muaj tej yam kev nyab xeeb; tsis zoo stability, siab tag nrho cov nqi; teeb meem sib dhos.
(2) Direct backlight
Cov qauv hauv qab no yog npaj cov LED tuag sib npaug tom qab LCD vaj huam sib luag raws li lub teeb ci, kom lub teeb rov qab tuaj yeem sib npaug mus rau tag nrho lub vijtsam, thiab cov ntsiab lus ntawm lub vijtsam yog qhov muag heev thiab muaj tiag.
qhov zoo:
1. Daim duab tau txais lub teeb thiab kub sib npaug, thiab cov duab xim yog qhov muag heev;
2. Muaj zog ruaj khov thiab tsis muaj kev nyab xeeb;
3. Tus nqi qis tag nrho;
4. Kev sib dhos yooj yim thiab ceev;
Qhov tsis zoo: lub cev tuab.
Hauv cov ntsiab lus, hom ncaj qha yog qhov kev xaiv zoo tshaj plaws rau cov ntsiav tshuaj nruab nrab thiab loj sib tham sib! Pob tshab electromagnetic kav hlau txais xov board yog qhov kev xaiv zoo tshaj plaws rau kev sib tham ncaj qha ncaj nraim!
Plaub, qhov zoo thiab qhov tsis zoo ntawm cov pob tshab thiab tsis yog pob tshab electromagnetic
1. Cov khoom tshiab, pob tshab electromagnetic, muaj peev xwm ua tau zoo heev electromagnetic kev sau ntawv ntawm ib sab tes, thiab ntawm qhov tod tes, lub teeb transmittance tshaj 90 feem pua, uas tsis cuam tshuam rau lub brightness, yog li nws yuav siv tau nyob rau hauv ncaj qha- lit backlight qauv los yog ntug-lit backlight. qauv;
2. Muab piv nrog cov tsoos nyiaj-txhuam txoj kev, cov luam ntawv pob tshab electromagnetic kav hlau txais xov board muaj qhov zoo ruaj khov thiab tsis yooj yim tawg; Nyob rau tib lub sijhawm, cov khoom tseem ceeb txais yuav cov txheej txheem laser vuam, uas ruaj khov thiab txhim khu kev qha, thiab muaj kev ruaj ntseg siab;
3. Cov luam ntawv pob tshab electromagnetic kav hlau txais xov board muaj qis pwm qhib tus nqi, zoo compatibility, thiab txo nqi tag nrho.
