Seminar Farsamo Oo Ku Saabsan Muhiimadda Pixel Pitch, Daawashada Fogaanta iyo Cabbirka Muujinta LED.

Ku rakibida derbiga fiidiyooga ee LED waxay sii wadaan inay beddelaan meelaha bannaan ee adduunka oo dhan.

Kaniisadaha, dugsiyada, xafiisyada, garoomada diyaaradaha iyo tafaariiqlayaasha ayaa abuuraya waayo-aragnimo firfircoon, firfircoon, xusuus leh meelo kala duwan oo gudaha iyo dibadda ah.

Haddii aad ka fekereyso bandhigga LED, mid ka mid ah doorashooyinkaaga ugu muhiimsan waa xulashada pixel pitch, laakiin waxaa laga yaabaa inaad la yaabto, waa maxay pixel pitch? Sidee buu cabirka pixel-ku u saameeyaa qiimaha? Maxay yihiin tixgelinnada muhiimka ah marka la dooranayo garoonka pixel?

Halkan hadda, AllowYonwaytecheeg sida aad u samayn karto doorashada saxda ah ee pixel pitch ee kaagaLED video derbimashruuc.

Marka hore, waa maxay pixel pitchs?

Darbiga LED-ka ayaa la iskula dhejiyaa muraayadaha LED-ka, kuwaas oo markooda ka kooban qaybo badan oo LED ah. Qaybahan LED waxa ku jira rucubyada LED-ka ama xirmooyinka LED-ka, ie guduud, buluug iyo nalka cagaaran (LEDs) oo lagu kooxeeyay pixels.

Dhererka pixel-ku waa masaafada u dhaxaysa bartamaha-ilaa-dhexe ee u dhaxaysa laba pixels, inta badan waxaa lagu qiyaasaa millimitir.

Haddii aad leedahay 10mm pixel pitch, waxay ka dhigan tahay in fogaanta u jirta bartamaha hal pixel ilaa bartamaha pixel ku xiga ay tahay 10 millimitir.

Marka labaad, Waa maxay saamaynta pixel pitchs ee tayada muuqaalka LED?

Goobta Pixel ayaa go'aamisa xallinta bandhiga LED, fogaanta ugu yar ee daawashada iyo fogaanta daawashada ugu fiican ee shaashadda LED.

Markasta oo ay yaraato booska pixel-ka, ayaa pixel-ku sii badanaya, waxayna keenaysaa tafaasiil badan iyo tayada muuqaal sare.

Markaa haddii aad u baahan tahay inaad ku muujiso muuqaallada xallinta sare ama fiidiyowga shaashaddaada, waxaad u baahan tahay bandhig LED leh oo leh garoon yar oo pixel ah.

Jaantuska soo socdaa wuxuu muujinayaa saamaynta garoonka pixel ee tayada sawirka, cufnaanta pixel yar waxay keenaysaa xalal sare iyo macluumaad faahfaahsan.

Marka saddexaad, fogaanta daawashada waa in la tixgeliyo marka aad dhiseyso bandhig hoggaamineed oo wanaagsan.

Dhererka Pixel wuxuu si toos ah u go'aamiyaa cufnaanta pixel-tirada pixels ee aagga shaashadda-iyo cufnaanta pixel ayaa si toos ah u go'aamisa fogaanta daawashada ee lagu taliyay - masaafada ka fog darbiga fiidiyowga daawade waa inuu lahaadaa waayo-aragnimo daawasho oo qancisa.

Garoonku marka uu sii fiicnaado, ama ka yaraado, ayaa ah mid u dhow fogaanta daawashada ee la aqbali karo.

Inta uu garoonku weynaado, waa inta uu ka sii fogaanayo daaweeyaha.

Pitch sidoo kale waxay si toos ah u saameysaa qiimaha, laakiin pixel weyn ee cabbir yar oo shaashad ah iyo masaafada dheer ee daawashada ama bandhiga cabbirka weyn laakiin fogaanta daawashada gaaban labaduba ma soo saari karaan waxqabad muuqaal ah oo soo jiidasho leh.

Si aad u dooratid booska ugu wanaagsan ee pixel laba arrimood waa in la tixgeliyaa, fogaanta daawashada iyo xallinta sawirka loo baahan yahay.

Maqaarka pixel-ka yar ayaa ka fiican mar walba waxayna ku siinayaan tayada muuqaal wanaagsan laakiin, kharash badan ayaa ku baxaya.

Waxaa laga yaabaa inaad hoos u dhigto kharashyada soo-bandhigidda LED-ka adigoo isticmaalaya garoonka weyn ee pixel oo weli aad leedahay tayada muuqaal la mid ah haddii masaafada daawashada ay ka dheer tahay masaafada ugu fiican.

Masaafada ugu fiican ee daawashada pixel pitch waa fogaanta indhuhu aanay awoodi doonin inay sii galaan farqiga u dhexeeya pixel haddii aad sii fogaato.

Hababka xisaabinta ee xulashada bandhigga LED ee ku habboon.

Sida kor lagu sharaxay, pixel pitch ayaa tixgelin weyn u ah habkan. Waxay la socotaa arrimo kale sida cabbirka bandhigga, fogaanta daawashada, xaaladaha iftiinka jawiga, ilaalinta cimilada iyo qoyaanka, warbaahinta tartamaya, shaqeynta fariimaha, tayada sawirka iyo wax badan, wax ka badan.

Bandhigyada LED-ka ee sida saxda ah loo geeyey waxay awood u leeyihiin inay kordhiyaan taraafikada, wanaajiyaan ka-qaybgalka dhagaystayaasha, iyo kor u qaadida khibradaha macaamiisha. Laakiin fahamka sida tignoolajiyadu u saameyn doonto labadaba daawadayaasha iyo xariiqdaada hoose ka hor maalgashiga waxay awood kuu siin kartaa inaad sameyso go'aanka ugu fiican ee baahiyahaaga gaarka ah iyo miisaaniyaddaada.

Heerarka qiimaynta adag ee macluumaadkaaga sida hoose:

Masaafada ugu yar ee daawashada: 

Shaashadda LED masaafada muuqata (M) = pixel Pitch (mm) x1000/1000
Fogaanta daawashada ugu fiican:

LED waxay soo bandhigaysaa fogaanta daawashada ugu fiican(M)= Pixel Pitch (mm) x 3000~ pixel Pitch (mm) /1000
Fogaanta daawashada ugu fog:

Fogaanta ugu fog (M)= dhererka shaashadda LED (m) x 30 jeer

Marka tusaale ahaan, bandhigga P10 wuxuu ku leeyahay ballac 10m ah oo dhererkiisu yahay 5m, masaafada ugu fiican ee daawashada waa ka fog tahay 10m, laakiin masaafada ugu badan ee daawashada waa 150mitir.
