Macaamiil kastaa wuxuu u baahan yahay inuu fahmo tilmaamaha farsamo si uu u doorto shaashadaha ku habboon iyadoo kuxiran baahiyahaaga.
1) Xarafka Pixel - Pixel pitch waa masaafada u dhexeysa laba pixels oo milimitir ah iyo cabirka cufnaanta pixel. Waxay go'aamin kartaa caddaynta iyo xallinta qaababka shaashaddaaga LED iyo masaafada ugu yar ee daawashada. Hada suuqyada ugu muhiimsan ee Pixel Pitch LED Model: 10mm, 8mm, 6.67mm, 6mm 5mm, 4mm, 3mm, 2.5mm, 2mm, 2.97mm, 3.91mm, 4.81mm, 1.9mm, 1.8mm, 1.6mm, 1.5mm, 1.25 mm, 0.9mm, iwm
2) Xallinta - Tirada pixels ee shaashadda ayaa go'aaminaya xallinta, oo loo qoray (ballaca ballaadhan) x (dhererka pixel) p. Tusaale ahaan, shaashad leh xallinta 2K: 1920x1080p waa 1,920 pixels ballaaran oo leh 1,080 pixels sare. Xallinta sare waxay ka dhigan tahay tayada muuqaalka sare iyo fogaanshaha daawashada dhow.
3) Iftiin - Halbeegyada cabbiraaddu waa nits. Fiilooyinka dibadda ee LED-ka waxay u baahan yihiin dhalaal sare ugu yaraan 4,500 nits si ay uga soo baxaan iftiinka qoraxda hoosteeda, halka darbiyada fiidiyowga ee gudaha ay kaliya u baahan yihiin dhalaal inta u dhexeysa 400 iyo 2,000 nits.
4) Qiimeynta IP - IP rating waa cabirka iska caabinta roobka, boodhka iyo waxyaalaha kale ee dabiiciga ah. Shaashadaha dibadda waxaa looga baahan yahay ugu yaraan IP65 (lambarka koowaad waa heerka ilaalinta ee ka hortagga walxaha adag, tan labaadna waa cabitaanno) qiimeynta si xasilooni loogu helo cimilo kala duwan iyo IP68 meelaha qaarkood oo roob urursaday, halka kuwa shaashadda gudaha ku jira ay sameyn karaan noqo mid ka adag. Tusaale ahaan, waad aqbali kartaa qiimeynta IP43 ee shaashadda gudaha ee kirada LED-ka.
5) Adiga ayaa kugula taliyay inaad soo bandhigto
P3.91 Bandhigga Dibadda ee muusigga muusigga, shirarka, garoonka, xafladda dabaaldega, bandhig bandhig, bandhig faneedyo iwm.
P2.5 Bandhigga Gudaha ee TV-ga, qolka shirarka, hoolka bandhigga, garoomada diyaaradaha, dukaamada iwm.
P6.67 Dayactirka Dibedda Dibedda ee Muuqaalka DOOH (Xayeysiinta Dijital ah ee Guryaha Ka Baxsan), Suuqa Dukaameysiga, Xayeysiinta Ganacsiga, iwm.
