1. Mawu Oyamba
Kukweza kwa madontho ndi ma pixel ndi zinthu zofunika pakuzindikira mtundu wazithunzi pazowonetsa pano. Pixel pitch ndi mtunda wa pakati pa pakati pa mapikseli awiri oyandikana pazenera, pomwe madontho amatanthawuza kutalikirana kwa madontho a phosphor pachiwonetsero cha CRT. Ngakhale kuti mawuwa amagwiritsidwa ntchito mobwerezabwereza, kukwera kwa pixel tsopano kumagwirizana kwambiri ndi zowonetsera za LCD, LED, ndi OLED.
Kufunika kwa Pixel Pitch mu Zowonetsera Zamakono
Kuchulukira kwa pixel kwa chiwonetsero kumakhudza mwachindunji pakuthwa, kumveka bwino, komanso mawonekedwe onse. Ma pixel ocheperako akuwonetsa kuti ma pixel amadzazana moyandikana, zomwe zimapangitsa kuti ma pixel awoneke bwino komanso zithunzi zomveka bwino. Komano, ma pixel okwera amatha kuyambitsa ma pixelation, makamaka akawonedwa chapatali, chifukwa ma pixel amatha kuwonekera.
Chidule cha Mapulogalamu
Pixel pitch imagwira ntchito yofunika kwambiri pamawonekedwe osiyanasiyana:
Makoma a kanema wa LED ndi zikwangwani za digito: Kuchulukira kwa ma pixel kumawonetsetsa kuti zithunzi zosasinthika, zowoneka bwino ngakhale patali kwambiri.
Zipinda zowongolera ndi ma situdiyo owulutsa: Kamvekedwe kakang'ono ka pixel ndikofunikira kuti mumve zambiri komanso mawonekedwe olondola amitundu.
Zipangizo zam'manja ndi zowonetsera za VR: Izi zimafuna kukweza kwa pixel kwabwino kwambiri pazochitikira zozama zokhala ndi mawonekedwe ochepa a pixel.
2. Kodi Dot Pitch kapena Pixel Pitch ndi chiyani?
Pixel pitch ndi mtunda wapakati pa pikseli imodzi ndi pakati pa pixel yotsatira, kuyezedwa mu mamilimita (mm). Muyezowu ndi wofunikira kwambiri pakuyesa kukuthwa ndi kumveka bwino kwa chithunzi chomwe chawonetsedwa, makamaka pazithunzi za LED ndi LCD. Kutsika kwa pixel kumatanthauza kuti ma pixel amadzazana moyandikana, zomwe zimapangitsa kuti ma pixel awoneke bwino komanso akuthwa, zithunzi zatsatanetsatane.
