Si loo wanaajiyo waayo-aragnimada aragtida, waxaa muhiim ah in la tixgeliyo masaafada ugu habboon ee daawashada bandhiggaaga LED-ka ee hufan.Si loo qiyaaso fogaanta daawashada ugu fican, waxa kaliya ee aad u baahan tahay inaad ogaato waa muuqaalka muuqaalka LED-ka fogaanta dhexda LED ilaa bartamaha kan xiga.
pixel pitch (mm) / (0.3 ~ 0.8) = Masaafada ugu fican ee daawashada (mm)
▶▶waa maxay pixel pitch
Tusaalooyinka fogaanta daawashada ugu wanaagsan:
| Moodeelka Bandhiga Daah-furnaanta ee Radiant LED | Muujinta muraayadda pixel ee LED | Kala duwanaanshaha daawashada ugu fican |
| Boodhka LED | 3 x 6 mm | 3.8 ~ 10.0 m |
| RDT-TP2.9 | 2.9 x 5.8 mm | 3 ~ 12 m |
| RDT-TP3.9 | 3.9x 7.8 mm | 4 ~ 30 m |
| RDT-TP7.8 | 7.8 x 7.8 mm | 8 ~ 50 m |

Sida loo qiyaaso cabbirka ugu habboon ee shaashadda LED-ka ee hufan
Bandhigyada hufan ee LED-ka ee caadiga ah waxaa loo habayn karaa cabbir kasta iyo qaab kasta.Laakiin sidee ayaad u qiyaasi kartaa cabbirka ugu fiican ee muuqaalkaaga gudaha booskaaga?Sida fogaanta daawashada, qiyaasida cabbirka bandhigga ugu fiican waxay inta badan ku salaysan tahay garoonka pixel.Asal ahaan, boosaska waaweyn ee pixels waxay la mid yihiin cabbirrada bandhigga ee waaweyn ee lagu taliyey, iyo beddelkeeda.
