Choyambirira Chophatikiza Circuit Chip IC DS90UB927QSQX/NOPB

Kufotokozera mwachidule:

Kuonjezera apo, mawonekedwe a DVI pa khadi lojambula ndi mawonekedwe a DVI-I, kuphatikizapo chizindikiro cha digito ndi chizindikiro cha analogi.Chifukwa chake, makadi ambiri ojambulira opanda mawonekedwe a VGA amatha kusinthidwa kuchokera ku mawonekedwe a DVI kupita ku VGA kudzera pa adapter yosavuta kapena chosinthira ma siginecha.DVI ndi HDMI zolumikizira ndi zolumikizira za digito, makamaka makadi ojambula okhala ndi zolumikizira za HDMI, zomwe zimathandizira protocol ya HDCP ndikuyala maziko owonera mapulogalamu a HD omwe ali ndi copyright.Komabe, makadi ojambula opanda HDCP protocol sangathe kuwonera makanema ovomerezeka a HD ndi mapulogalamu a pa TV mosasamala kanthu kuti alumikizidwa ndi oyang'anira kapena TVS.

Ntchito

DVI mawonekedwe lagawidwa mitundu iwiri.Imodzi ndi mawonekedwe a DVI-D, omwe amatha kulandira zizindikiro za digito.Pali mizere itatu yokha ndi mizere 8 ya mapini 24 pa mawonekedwe, pomwe pini imodzi kukona yakumanja yakumanja ilibe kanthu.Sizogwirizana ndi ma analogi.

Zina ndi mawonekedwe a DVI-I omwe amagwirizana ndi ma analogi ndi ma digito.Kugwirizana kwa chizindikiro cha analogi sikutanthauza kuti mawonekedwe a d-sub a chizindikiro cha analogi akhoza kugwirizanitsidwa ndi mawonekedwe a DVI-I, koma ayenera kugwiritsidwa ntchito kupyolera mu cholumikizira chotembenuka.Nthawi zambiri, khadi lojambula lomwe limagwiritsa ntchito mawonekedwewa lidzakhala ndi cholumikizira chogwirizana.

Pazifukwa zofananira, makadi ojambula nthawi zambiri amagwiritsa ntchito doko la DVI-I, lomwe limatha kulumikizidwa ku doko la VGA wamba kudzera pa cholumikizira chosinthira.Mawonekedwe a DVI-D amagwiritsidwa ntchito kwa oyang'anira omwe ali ndi DVI, chifukwa oyang'anira otere alinso ndi VGA, kotero samasowa DVI-I yokhala ndi ma analogi.Kupatulapo zochepa, oyang'anira ena ali ndi madoko a DVI-I okha ndipo alibe madoko a VGA.Mawonekedwe a DVI pazida zowonetsera ali ndi zabwino ziwiri izi:

Liwiro mwachangu

DVI ndi kufala kwa chizindikiro cha digito, safuna kutembenuka kulikonse, chidziwitso cha digito chidzaperekedwa mwachindunji ku chipangizo chowonetserako, motero kuchepetsa kutembenuka kwa digito ndi analogi ku trival ndondomeko ya kutembenuka kwa digito, kupulumutsa kwambiri nthawi, kotero kumakhala mofulumira, kuthetsa vutoli. za ghosting, DVI ndi zomwe zimagwiritsidwa ntchito pofalitsa deta, kuchepetsa ma sign, palibe mtundu wangwiro, wowoneka bwino.

Kutanthauzira Kwapamwamba Kwambiri

Zomwe kompyuta imatumiza mkati ndi chizindikiro cha digito.Ngati mawonekedwe a VGA agwiritsidwa ntchito kulumikiza LCD, chizindikirocho chiyenera kusinthidwa kukhala R, G, B chizindikiro choyambirira cha mtundu ndi mzere ndi mzere wogwirizanitsa chizindikiro kudzera mu D/A (digital/analog) converter mu khadi lojambula.

Zizindikirozi zimatumizidwa ku kristalo wamadzimadzi kudzera mu mizere ya siginecha ya analogi ndipo chosinthira chofananira cha A/D (analogi/digito) chikufunika kuti chisandutse chizindikiro cha analogi kukhala chizindikiro cha digito kachiwiri chithunzicho chisanawonetsedwe pamadzi amadzimadzi.Muzotchulidwa pamwambapa D / A, A / D kutembenuka ndi njira yotumizira zizindikiro, kutayika kwa chizindikiro ndi kusokoneza kudzachitika mosakayikira, zomwe zimabweretsa kusokoneza kwa zithunzi komanso ngakhale kuwonetsa zolakwika.Komabe, mawonekedwe a DVI safunikira kuchita kutembenuka uku, kupewa kutayika kwa ma siginecha, kotero kuti kumveka bwino kwa chithunzi ndi kufotokozera kwasinthidwa bwino kwambiri.

Pomaliza, mawonekedwe a DVI amatha kuthandizira protocol ya HDCP, kuyala maziko owonera kanema wamtundu wa HD.Komabe, kuti apange zithunzi khadi thandizo HDCP, kuwala DVI mawonekedwe sizingatheke, ayenera kukhazikitsa chip odzipereka, komanso kulipira mkulu HDCP chindapusa kutsimikizika, kotero kwenikweni thandizo HDCP protocol zithunzi khadi si kwambiri.
