HVGA vs WVGA
Cov kev daws teeb meem ntawm lub vijtsam xa mus rau cov pixels ib qho kev saib xyuas hauv ib cheeb tsam. Cov kev daws teeb meem no, hu ua graphic display resolutions, feem ntau cuam tshuam rau lub computer saib thiab cov ntxaij vab tshaus mobile. Muaj ntau qhov sib xyaw ua ke ntawm cov kev daws teeb meem no nrog ntau qhov dav thiab qhov siab. Raws li cov kev sib txuas no feem ntau siv rau cov ntxaij vab tshaus ntawm lub xov tooj ntawm tes los ntawm cov tuam txhab hluav taws xob, ntau ntawm lawv tau ua qauv thiab txawm tias muab cov npe kom yooj yim nco txog cov pixels ntawm txhua qhov kev sib txuas no xa mus. HVGA thiab WVGA yog ob qho kev sib xyaw nto moo uas feem ntau siv los ntawm cov tuam txhab saib xyuas lub computer thiab cov chaw tsim khoom lag luam mobile. Cia peb kawm paub qhov txawv ntawm ob qhov kev daws teeb meem no.
HVGA
HVGA kuj hais txog ib nrab Loj VGA (Video Graphics Array). Lub vijtsam hauv HVGA muaj ntau qhov sib txuas ntawm pixels nyob ntawm qhov sib piv. Qee cov pixels no yog 480 × 320 (3: 2 nam piv), 480 × 360 pixels (4: 3 nam piv), 480 × 272 (16: 9 nam piv) thiab thaum kawg 640 × 240 pixels (8: 3 piv). Qhov pib pixel ua ke hauv HVGA yog siv los ntawm ntau cov khoom siv PDA. Ntawm qhov tod tes, qhov kawg ntawm qhov sib piv yog siv los ntawm ntau lub xov tooj ntawm tes PC manufacturers. Qee cov qauv nrov uas siv HVGA yog Blackberry Bold, LG GW620, HTC Hero, thiab Samsung M900. Qee qhov projector manufacturers xws li Texas Instruments tseem siv HVGA daws teeb meem. 3D computer graphics tau siv HVGA thaum xyoo 1980's.
WVGA
hom kev daws teeb meem no tseem hu ua Wide VGA (Video Graphics Array). Hom zaub no muaj qhov siab tib yam li VGA uas yog 480 pixel qhov siab tab sis nws dav dua. Qee qhov piv txwv yog 800 × 480, 848 × 480, thiab 854 × 480. Cov zaub no feem ntau pom nyob rau hauv LCD projectors thiab phau ntawv uas yooj yim tso saib cov vev xaib uas tsim los rau lub qhov rais uas yog 800 qhov dav ntawm nplooj ntawv dav. WVGA niaj hnub no nyiam los ntawm ntau lub tuam txhab tsim khoom lag luam.
In luv:
