Cov kua siv lead ua kua cell LCD npo cuam tshuam rau qhov tsis xws luag. Rau lub 1024x768 npo, txhua lub pixel yog tsim los ntawm peb chav nyob, lub luag haujlwm rau cov ntawv liab, ntsuab, thiab xiav - yog li tag nrho ntawm kwv yees li 2 lab 400 txhiab units (1024x768x3 = 2359296) yuav tsum muaj. Nws yog qhov nyuaj kom paub meej tias tag nrho cov koog nyob hauv tus nqi. Feem ntau cov yuav tuaj yeem, uas tau ua ib feem ntawm lub luv Circuit Court ("tsaus"), lossis qhib ("ci pom kev"). Qee tus neeg muas zaub yuav xav tias xws li tus nqi siab yuav tsum yuav lub LCD zaub zoo meej - thiab hmoov tsis zoo nws tsis yog qhov tseeb, thiab tuaj yeem tuaj tos txais ntau tshaj plaws dawb - lub sijhawm ntsuas.

Cov zaub LCD muaj qee yam uas tsis tau siv CRT thev naus laus zis. Vim tias cov kua siv lead ua kua nws tus kheej tsis ci, nws tswj lub backlight los ntawm kev kho qhov kev npaj ntawm cov kua muaju, yog li nws cov xim siv zog yog txawv ntawm CRT zaub. Piv txwv, qee cov qauv meej heev (xws li jitter txheej txheem cov duab) yuav tshwm sim cov dab ros los yog cuam tshuam cov qauv ntawm LCD npo. Tseem muaj qhov pom lossis "lub kaum ntse ntse soj" teeb meem. Yog vim li cas rau lub hav zoov ntawm LCD yog lub teeb xa kis, uas tswj lub teeb kis los ntawm kev tshuaj ntsuam. Thiab CRT yog lub tshuab pa hluav taws. Rau CRT, cov khoom tshwj xeeb tom qab lub vijtsam (phosphor) tuaj yeem nquag tawm lub teeb. Hauv LCD, txawm hais tias lub teeb tuaj yeem nkag mus rau qhov tseeb pixels, lub teeb tilted kuj nkag mus rau cov pixels uas nyob ib sab, yog li cov xim tau cuam tshuam loj heev thaum saib ntawm sab nraum lub kaum sab xis ntawm kev pom.
