Markaad dooranayso muraayad yar oo LED ah, dhowr arrimood oo muhiim ah ayaa loo baahan yahay in la tixgeliyo:
1. Pixel Pitch:
Dhererka Pixel waxaa loola jeedaa masaafada u dhaxaysa pixels LED ee ku xiga, oo badanaa lagu qiyaaso millimitir (mm). Meel yar oo pixel ah waxay keentaa xallinta shaashadda sare, oo ku habboon daawashada dhow. Doorashada pixel pitch waa in ay ku salaysnaato muuqaalka isticmaalka iyo fogaanta daawashada.
2. Iftiin:
Iftiiminta muraayadaha LED-ga-yar-yar waa inay ahaadaan kuwo dhexdhexaad ah. Iftiinka xad-dhaafka ah ayaa laga yaabaa inuu keeno daal indhaha, halka dhalaal la'aanta ay saameyn ku yeelan karto tayada bandhigga. Guud ahaan, dhalaalka bandhigyada gudaha ayaa ku habboon inta u dhaxaysa 800-1200 cd/m².
3. Sicirka Cusbooneysii:
Qiyaasta dib-u-cusboonaysiinta waa tirada wakhtiyada ay shaashadu cusboonaysiinayso sawirka ilbiriqsikii, laguna cabiray Hertz (Hz). Heerarka dib-u-cusboonaysiinta sare waxay yaraynaysaa libdhka shaashadda waxayna wanaajisaa xasilloonida bandhigga. Tani waxay si gaar ah muhiim ugu tahay baahinta tooska ah iyo goobaha istuudiyaha halkaasoo kamaradaha xawaaraha sare leh lagu isticmaalo.
4. Heerka cawl:
Heerka cawl waxa loola jeedaa awoodda shaashadda si ay u muujiso dhibcaha midabka iyo tafaasiisha daahsoon. Heerarka cawl ee sarreeya wuxuu keenaa midabyo qani ah iyo sawirro nolol u eg. Heerka cawl ee 14 bits ama ka sareeya ayaa guud ahaan lagula talinayaa.
5. Isbarbardhigga:
Saamiga isbarbardhigga ayaa cabbiraya faraqa u dhexeeya qaybaha ugu mugdiga iyo iftiinka badan ee shaashadda. Saamiga isbarbardhigga sare wuxuu wanaajiyaa qoto dheeraanta sawirka iyo hufnaanta, gaar ahaan muhiim u ah soo bandhigida muuqaallada ama muuqaallada taagan.
6. Xagasha Daawashada:
xagasha daawashada waxaa loola jeedaa waxtarka shaashada marka dhinacyo kala duwan laga eego. Bandhigyada LED-yada yar-yar waa inay lahaadaan xagal daawasho ballaaran si loo hubiyo dhalaal joogto ah iyo midab dhinacyo kala duwan leh.
7. Kulaylka Kala-baxa:
Heerkulka shaqada ee bandhigyada-pitch LED-yada ayaa si weyn u saameeya cimrigooda iyo tayada bandhigga. Naqshadaynta kulaylka wanaagsan waxay si wax ku ool ah u yaraynaysaa heerkulka, kordhinaysa cimriga shaashadda.
8. Rakibaadda iyo Dayactirka:
Tixgeli fududaynta rakibidda iyo dayactirka shaashadda. Naqshadaynta qaab-dhismeedka iyo doorashooyinka dayactirka hore/dhabarku waxay saamayn ku yeelan karaan khibradda isticmaale iyo kharashyada dayactirka.
9. Gudbinta ishaarada:
Hubi in shaashadu ay taageerto gudbinta calaamada degan, yaraynta daahitaanka iyo luminta calaamada, iyo hubinta isku xidhka sawirka wakhtiga dhabta ah.
10. Summada iyo Adeegga:
Doorashada magacyo sumcad leh oo leh adeeg iibka kadib oo aad u wanaagsan waxay hubisaa tayada badeecada iyo taageerada farsamada ee waqtiga, yaraynta walaaca inta lagu jiro isticmaalka.
Adigoo si buuxda u tixgelinaya arrimahan oo aad dooranayso bandhig yar oo LED ah oo ku habboon baahida dhabta ah, waxaad ku gaari kartaa saameynta bandhigga ugu fiican iyo khibradda isticmaalaha.
