Pepalali likufotokoza zomwe zimayambitsa ndi mayankho azomwe zimakokera mawonekedwe amtundu wamtundu wamtundu wa LED wowoneka bwino kwambiri!
Mawonekedwe amtundu wamtundu wa LED nthawi zambiri amakhala akusewerera kanema mu lupu, ndipo chiwonetserochi chowoneka bwino chimatengera mphamvu ya parasitic ya chigawocho kapena mzerewo ukasinthidwa mzere, kupangitsa magetsi ena a LED omwe sayenera kuyatsidwa pano. mphindi yowoneka mdima, yomwe imatchedwa "kukoka mthunzi" chodabwitsa.
Zifukwa zazikulu za zochitika zokoka ndi izi:
① Vuto loyendetsa khadi la kanema.Mutha kuyesa kusinthira dalaivala wamakhadi azithunzi kapena kukhazikitsanso dalaivala wamakhadi ojambula.Panthawi imodzimodziyo, tikulimbikitsidwa kusintha kusintha ndi kutsitsimula, zomwe zingagwirizanenso ndi nthawi yoyankhira ya LCD.
② Vuto la khadi la kanema.Mutha kuyesanso kulumikizanso ndikuyeretsa chala chagolide.Nthawi yomweyo, mutha kuwona ngati wokonda makhadi azithunzi amagwira ntchito bwino.
③ Vuto la mzere wa data.Ndikofunikira kusintha chingwe cha data kapena kuwona ngati chingwe cha data chikupindika.
④ Vuto la chingwe chazenera.Ndiko kuti, VGA chingwe.Yang'anani ngati chingwechi chalumikizidwa bwino komanso ngati chamasuka.Yesani kusintha chingwe chapamwamba cha VGA.Kuphatikiza apo, chingwe cha VGA chiyenera kukhala kutali ndi chingwe chamagetsi.
⑤ Kuwonetsa vuto.Lumikizani chowunikira ku kompyuta ina yabwinobwino.Ngati vutoli likupitirira, likhoza kukhala vuto la polojekiti.
Ukadaulo wochotsa mthunzi wa skrini yowonetsera ya LED ungapangitse chithunzithunzi kukhala chosalimba ndikupangitsa kuti chithunzicho chifikire kutanthauzira kwakukulu kwa chithunzi;Kugwiritsa ntchito mphamvu pang'ono kumatha kupulumutsa mphamvu yamagetsi pakugwiritsa ntchito kwanthawi yayitali chiwonetsero cha LED kuti chikwaniritse zofunikira zakugwiritsa ntchito mtengo wotsika komanso kuteteza mphamvu ndi kuteteza chilengedwe;Kukwera kotsitsimula kumapangitsa kuti chithunzi chowonetsera chikhale chokhazikika, chopereka chithandizo chaumisiri chowonetsera bwino komanso chapamwamba kwambiri, ndipo zotsatira zowonetserazi zimapangitsanso diso laumunthu kukhala lotopa poyang'ana, ndipo limatha kukwaniritsa zosowa za kujambula kothamanga kwambiri.Izi ndizomwe zalimbikitsa kusintha kwa machitidwe m'mbali zonse, komanso kulimbikitsa kwambiri chitukuko cha teknoloji yogwiritsira ntchito chophimba chonse cha LED.
Ukadaulo wamakono wochotsa mthunzi umathetsa bwino vuto la kukoka.Pamene ROW (n) mzere ndi ROW (n+1) mizere kusintha mizere, panopa mthunzi kuchotsa ntchito basi mlandu parasitic capacitance Cc.Pamene mzere wa ROW (n + 1) uli, mphamvu ya parasitic Cc sichidzaperekedwa kudzera mu nyali 2, motero kuchotsa chodabwitsa chokoka.
Pofuna kuchepetsa kugwiritsa ntchito mphamvu zowonetsera ma LED, zida zamphamvu zotsika zidayambitsidwa.Chepetsani mphamvu yamagetsi yamagetsi yowonetsera ma LED pochepetsa mphamvu yamagetsi yamagetsi yapano.Njirayi imachepetsanso mphamvu zamagetsi, zomwe zimatha kuthetsa kukana kwa 1V voteji dontho lomwe liyenera kulumikizidwa mndandanda wa kuwala kofiira.Kupyolera muzosintha ziwirizi, kugwiritsa ntchito mphamvu zochepa komanso ntchito zapamwamba zingatheke.
Mwachidule, kaya ndi teknoloji yochotseratu kapena teknoloji yamakono yochotseratu, ntchito yofunikira kwambiri ya teknoloji yoyendetsa galimoto ndikupangitsa chithunzicho kukhala chokhazikika komanso chomveka bwino, monga momwe makhadi amajambula pakompyuta, kuonetsetsa kuti chithunzicho chili bwino, ndipo potsiriza kukwaniritsa. chiwonetsero cholondola chatsatanetsatane chamtundu wamtundu wa LED.
