Qhov zoo thiab qhov tsis zoo ntawm cov hom kev hloov hauv LCD
May 05, 2018
Raws li cov txuj ci, cov ntawv qhia hauv LCD tau faib ua tsib yam loj: OLED, TFT-LCD, TFD-LCD, SIN-LCD, thiab GF-LCD. Raws li cov teeb pom kev zoo siv tshuab LCD kuj tseem yuav muab faib ua duab LCD thiab transmissive LCD.
Lub teeb duab transmissive relies on backlight qhov chaw thiab consumes tus loj npaum li cas ntawm lub hwj chim, tab sis cov reflective LCD tsis yuav tsum muaj kev kos duab. Nws nyob rau ntawm cov teeb pom kev zoo hauv ambient thiab muaj lub hwj huam qis thiab tsim nyog rau cov khoom hluav taws xob xws li cov xov tooj ntawm tes thiab cov PDAs. Yog li, tus lej LCD siv. Lub sijhawm ntev tshaj ntawm kev tshawb fawb. Hauv qhov ua ntej los tiv thaiv hom LCD, lub 90 ° TN hom siv, thiab siv ob daim npov polarizing. Tom qab ntawd, ib qho kev sib txuam hom TN thiab ib hom VA uas siv lub polarizer tau npaj siab. Qhov tsis zoo ntawm tus lej LCD yog qhov teeb meem ntawm lub teeb pom kev zoo ntawm lub vaj huam sib luag nrog qhov sib npaug ntawm 5: 1-30: 1. Txij li thaum lub LCD nthuav dav yog siv rau e-phau ntawv thiab lwm yam khoom, nws yuav tsum ua kom tiav cov ntaub ntawv ntawm kev sau, xws li 70% -90%.
Semi-retro LCD
Semi-transparent LCD yog abbreviated li TR-LCD, uas yog ib tug transmissive thiab reflective compound lo lus. Hauv kev teeb tsa TR-LCD, txij thaum lub teeb pom kev zoo los ntawm cov kua siv lead ua kua ob zaug, qhov kev pom ntawm lub teeb pom kev zoo thiab qhov chaw uas pom tau tias yog teeb ci tuaj ob zaug.
Qhov kev tsis zoo ntawm TR-LCD yog qhov uas thaum lub teeb ci ntsa iab tsis tsaus, tsis muaj teeb pom kev, qhov kev lag luam ntawm qhov chaw sib kis thiab cheeb tsam ntawm lub cheeb tsam no yog ib zaug uas tau pom, uas txo cov duab ntawm cov duab zoo. Tsis tas li ntawd, nyob rau hauv cheeb tsam ntawm lub cheeb tsam, lub teeb kis tau los ntawm cov xim lim txheej ob zaug, thiab muaj ib lub xim txawv nyob hauv daim duab ntawm lub cheeb tsam ntawm lub cheeb tsam thiab qhov chaw sib kis kab mob. Rau qhov xim hloov qhov teeb meem, Ntse tau tsim TR-LCD qauv uas cov xim ntawm cov xim tha xim ntawm cov cheeb tsam yuav yog txo los ntawm 1/2.
Kev tsim cov txheej txheem ntawm kev tsim cov cheeb tsam thiab cov cheeb tsam hauv cov cheebtsam uas muaj ntau qhov sib txawv hauv cov kua qe ntshav hauv dej yog qhov teebmeem, thiab kev tsav tsheb ntawm lub cheebtsam thiab thaj chaw yog qhov txawv txav, uas coj ntau yam teeb meem hauv kev tsim tawm thiab daim ntawv thov.
