Raws li cov khoom siv tshuaj ntsuam, cov ntxaij vab tshaus hauv xov tooj tseem tuaj yeem muab faib ua ob pawg: LCD (Liquid Crystal Display), xws li TFT thiab SLCD cov ntxaij vab tshaus; thiab OLED (Organic Light-Emitting Diode), xws li AMOLED cov ntxaij vab tshaus. Qhov sib txawv ntawm LCD thiab OLED yog tias OLED yog tus kheej -emissive, thaum LCD xav tau lub teeb rov qab los tso saib.
Raws li kev siv thev naus laus zis thiab kev tsav tsheb, cov ntxaij vab tshaus tuaj yeem muab faib ua ob pawg loj: passive matrix thiab active matrix. Qhov txawv ntawm passive thiab active matrices nyob rau hauv txoj kev tsav tsheb tam sim no. Thaum ib qho hluav taws xob sab nraud dhau mus, qhov kev npaj ntawm cov kua muaju hloov pauv. Yog tias cov kua siv lead ua kua tswj lawv qhov kev npaj ua ntej tom qab nres tam sim no (muaj kev nco), nws yog hu ua active matrix; thaum yog lawv rov qab mus rau lawv txoj haujlwm qub sai li sai tau thaum tam sim no ploj mus thiab yuav tsum tau them rov qab rau re-align, nws yog hu ua passive matrix.
