Vim li cas Brightness yog qhov Spec Uas Ua Rau Cov Neeg Yuav Tsum Muaj Teeb Meem Feem ntau
Qhov xwm txheej tiag tiag: 400-nit display deployed sab nraum zoov - unreadable kiag thaum tav su
Lub tuam txhab logistics tau teeb tsa tus qauv 400-nit 7-nti zaub hauv cov tsheb sab nraum zoov. Nyob rau hnub tshav ntuj, cov neeg ua haujlwm tsis tuaj yeem nyeem cov ntaub ntawv tseem ceeb, ua rau muaj teeb meem kev nyab xeeb thiab kev hloov chaw kim.
Qhov teeb meem rov qab: 1500-nit vaj huam sib luag nyob rau hauv daim ntawv thov chaw ua hauj lwm - tsis tsim nyog nqi thiab kub
Ib txoj haujlwm HMI sab hauv tsev tau siv ultra- siab- cov vaj huam sib luag ci ntsa iab, ua rau muaj kev siv hluav taws xob ntau dua, qhov kub thiab txias ntawm cov ntaub thaiv npog, thiab cov nqi nce ntxiv uas tsis pom muaj txiaj ntsig.
Vim li cas qhov ci ci tsis yog qhov kev txiav txim siab "cia li mus siab dua".
Daim ntawv qhia no npog dab tsi thiab yuav siv nws li cas los txiav txim siab
