Raws li lub tuam txhab ua lag luam LED iav nrog ntau tshaj 20 xyoo ntawm kev paub, RAM yeej ib txwm tsom rau cov khoom lag luam thiab txhim kho cov neeg siv khoom. Yog li, RAM muaj kev tshawb fawb thiab kev txhim kho muaj peev xwm thiab tuaj yeem kho cov qauv tsim raws li cov neeg siv khoom xav tau.
Peb cov engineers tsim cov kev daws teeb meem tsim nyog thiab ua tau raws li cov neeg siv khoom xav tau, thiab tsim cov khoom siv hluav taws xob sib txuas lossis cov hloov hluav taws xob hauv lub tuam tsev tsim hluav taws xob, uas tau hloov kho kom zoo rau cov iav LED. Qhov no ua rau peb cov khoom tsis yog tsuas yog muaj ntau yam kev ua haujlwm, tab sis kuj ua kom muaj kev ua tau zoo thiab kev nyab xeeb. Txawm hais tias koj xav tau kev ua haujlwm yooj yim lossis muaj zog dua, peb tuaj yeem ua tau raws li koj xav tau.
Peb ib txwm ua raws li txoj cai ntawm cov neeg siv khoom ua ntej, muab cov khoom lag luam zoo thiab cov kev pabcuam zoo rau peb cov neeg siv khoom los ntawm kev nkag siab txog lawv cov kev xav tau thiab cov neeg siv khoom-centric tsim cov tswv yim.
