Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, kev siv cov ntxaij vab tshaus LCD yog dav heev nyob rau hauv lub neej txhua hnub, vim hais tias cov yam ntxwv ntawm txhua yam khoom yog txawv, thiab txhua parameter muaj lub ntsiab lus. Nws siv tau dav heev, suav nrog kev lag luam, laptop, kov, kho mob, tsheb, desktop saib, TVs, thiab lwm yam.
Feature 1: Cia tam sim no dhau los ntawm cov kua siv lead ua kua txheej, thiab cov molecules yuav ntws nrog rau tam sim no Npaj cov kev taw qhia.
Feature 2: Yog tias tsis muaj tam sim no dhau los, lawv yuav tau teem caij sib luag. Yog tias koj muab txheej txheej nrog cov grooves me me, tom qab nchuav cov kua, cov kua molecules yuav ua raws li cov grooves, thiab cov txheej sab hauv thiab sab nrauv yuav ua tib yam.
Feature 3: Cov txheej txheem ua kua tuaj yeem ua rau lub teeb sib tw. Cov txheej ua kua qhia tau qee qhov kev ua tau zoo Ib yam li lub polarizer, qhov no txhais tau hais tias nws tseem tuaj yeem lim tawm txhua yam tshwj tsis yog cov los ntawm cov lus qhia tshwj xeeb rau txhua lub teeb rays uas nkag mus dhau.
Txoj haujlwm ua haujlwm:Cov kua siv lead ua kua yog cov organic sib xyaw nrog cov txheej txheem molecular tsis tu ncua. Nws tsis yog ib qho khoom lossis cov kua, tab sis yog cov khoom nruab nrab ntawm cov khoom thiab cov kua. Thaum rhuab, nws tshwm nyob rau hauv lub pob tshab kua lub xeev, thaum lub sij hawm txias, nws tshwm nyob rau hauv ib tug cloudy khoom lub xeev ntawm crystalline hais. Muab cov kua siv lead ua kua cell ntawm ob qho tib si iav substrates, nrog nyias zaj duab xis transistors ntawm cov iav substrate qis thiab cov xim lim rau ntawm lub khob sab saud. Tswj cov kev taw qhia kev sib hloov ntawm cov kua siv lead ua kua molecules los ntawm kev hloov lub teeb liab thiab voltage ntawm nyias zaj duab xis transistors, yog li ua tiav lub hom phiaj ntawm kev tswj xyuas seb txhua pixel emits polarized lub teeb.
Cov kua dej tau muab faib ua passive matrix LCD thiab nquag matrix L raws li kev tswj sib txawv. Passive matrix LCD muaj qhov ci ntsa iab thiab pom lub zog, thiab nws cov lus teb ceev kuj qeeb, tab sis nws yog me me thiab pheej yig.
Qeb:
1. TN-LCD (Twisted Nematic Lp Push LcD)
2. STN-LCD (SuperTN LCD)
3. DSTN LCD (Ob chav txheej STN-LcD dual txheej super twisted nematic LCD)
LCD (luv rau Liquid Crystal Display) yog hom kua siv lead ua kua. Cov qauv ntawm lub LCD yog tso cov kua siv lead ua kua cell ntawm ob qho tib si iav substrates, nrog TFT (nyias zaj duab xis transistor) nyob rau hauv qis substrate iav thiab xim lim rau sab sauv substrate iav. Kev sib hloov ntawm cov kua siv lead ua kua molecules yog tswj los ntawm lub teeb liab thiab voltage hloov ntawm TFT, yog li ua tiav lub hom phiaj ntawm kev tswj xyuas seb txhua pixel emits polarized lub teeb los yog tsis. Niaj hnub no, LCD tau hloov CRT raws li lub ntsiab, thiab nws cov nqi kuj tau poob qis, thiab nws tau nrov nrov.
