Piv nrog ob hom kua siv lead ua kua hauv cov kab lus dhau los, kev ua tau zoo ntawm kev siv tshuab yog me ntsis tsis zoo. Nws tsis tuaj yeem pom qhov xim zoo nkauj ntawm 16.7M, thiab tsuas tuaj yeem ua tau 16.7M xim (6bit vaj huam sib luag) tab sis lub sij hawm teb yog yooj yim los txhim kho. Lub kaum sab laj pom tseem yog txwv. Lub kaum sab xis pom tsis tshaj 160 degrees. Hauv cov khw muag khoom tam sim no, cov khoom uas feem ntau hauv 8 xuab moos sij hawm teb mas feem ntau yog TN LCD panels.
