Maxay yihiin qodobbada muhiimka ah ee ay tahay in isticmaalayaashu fiiro gaar ah u yeeshaan marka ay dhab ahaantii iibsanayaan muraayad yar oo LED ah?
1. "Iftiin hoose iyo cawl sare" waa aasaaska
Sida terminalka bandhiga, muraayadda muraayadda LED-ka ee meel yar oo buuxa waa in ay hubisaa raaxada daawashada.Sidaa darteed, marka wax la iibsanayo, walaaca koowaad waa iftiinka.Cilmi-baadhisyo la xidhiidha ayaa muujisay, marka la eego dareenka indhaha bini'aadamka, LED, oo ah isha iftiinka firfircoon, dhalaalkeedu waa laba jeer ka ilbaxsan iftiinka (projector iyo LCD).Si loo hubiyo raaxada indhaha bini'aadamka, kala duwanaanta dhalaalka ee meel yar oo midab buuxa ah oo LED ah waxay noqon kartaa inta u dhaxaysa 100 cd / ㎡ iyo 300 cd / ㎡.Si kastaba ha noqotee, teknoolojiyadda bandhigga LED-ka ee dhaqameed ee buuxa, yaraynta iftiinka shaashadda waxay sababi doontaa luminta miisaanka cawl, luminta miisaanka cawl wuxuu si toos ah u saameyn doonaa tayada sawirka.Sidaa darteed, halbeegga xukunka muhiimka ah ee tayada-yar-yar ee muuqaalka buuxa ee midabka LED-ka waa in la gaaro tusmada farsamada ee "iftiin hoose iyo cawl sare".Iibka dhabta ah, isticmaalayaashu waxay raaci karaan mabda'a "heerka dhalaalka badan ee lagu aqoonsan karo isha bini'aadamka, si ka wanaagsan".Heerka dhalaalka waxaa loola jeedaa heerka dhalaalka ee sawirka madow ilaa caddaan oo lagu kala saari karo isha aadanaha.Heerarka dhalaalka ee la aqoonsan yahay, ayaa sii weynaanaya booska gamut ee shaashadda, iyo way sii weynaan kartaa suurtagalnimada muujinta midabyo qani ah.
2. Markaad dooranayso kala dheeraynta dhibcaha, fiiro gaar ah u yeelo dheelitirka "saamaynta iyo farsamada"
Marka la barbar dhigo shaashadda LED-ka ee soo jireenka ah, muuqaalka caanka ah ee kala dheeraynta yar ee shaashadda midabka buuxa ee LED waa farqiga dhibcaha yar.Codsiyada wax ku oolka ah, inta yar ee kala dheereynta dhibcaha ayaa ah, sare u kaca cufnaanta pixel, iyo awoodda macluumaadka dheeraadka ah ee aagga cutubka ayaa la soo bandhigi karaa hal mar, fogaanta ku habboon daawashada waa dhow.Taas lidkeeda, fogaanta ku habboon daawashada waa fogaanta.Isticmaalayaal badan ayaa si dabiici ah u malaynaya in yaraynta farqiga u dhexeeya dhibcaha alaabta, ay ka sii fiicnaan doonto.Si kastaba ha ahaatee, xaaladdu sidaas maaha.Shaashadaha LED-yada ee caadiga ah waxay rabaan inay helaan muuqaalo muuqaal ah oo wanaagsan oo ay leeyihiin fogaan arag oo wanaagsan, sidaas oo kale waxay sameeyaan shaashado LED ah oo midab buuxa leh.Isticmaalayaashu waxay samayn karaan xisaabin fudud iyada oo loo marayo fogaanta daawashada wanaagsan = farqiga dhibcaha / 0.3 ~ 0.8.Tusaale ahaan, fogaanta daawashada wanaagsan ee P2 shaashada kala dheeraynta yar ee LED waxay u jirtaa ilaa 6 mitir.Waxaan ognahay in farqiga u yar ee dhibcaha, ay sare u kacdo qiimaha kala dheereynta yar ee muraayadda LED-ka ee midabka buuxa.Sidaa darteed, iibsashada dhabta ah, isticmaalayaashu waa inay tixgeliyaan kharashkooda, dalabkooda, kala duwanaanshaha codsiga iyo arrimo kale.
3. Markaad dooranayso xallinta, fiiro gaar ah u yeelo is-waafajinta "qalabka gudbinta signallada-dhamaadka hore"
Markasta oo ay yaraato farqiga dhibcaha ee muraayadda yar ee midabka buuxa ee LED, ayaa sare u kaca xallinta, iyo sare u qaadida qeexida sawirka.Hawlgalka wax ku oolka ah, haddii dadka isticmaala ay rabaan inay dhisaan nidaam bandhig wanaagsan oo LED ah oo leh kala fogaansho yar, waa inay sidoo kale tixgeliyaan isku dhafka shaashadda iyo alaabta gudbinta calaamadaha hore iyagoo fiiro gaar ah u leh xallinta shaashadda lafteeda.Tusaale ahaan, codsiga ilaalinta amniga, nidaamka kormeerka-dhamaadka hore guud ahaan waxaa ku jira D1, H.264, 720P, 1080I, 1080P iyo qaababka kale ee calaamadaha muuqaalka.Si kastaba ha noqotee, ma aha dhammaan bandhigyada LED-ka buuxa ee meel yar oo ku yaala suuqa ma taageeri karaan qaababka kor ku xusan ee calaamadaha fiidiyowga.Sidaa darteed, si looga fogaado qashinka hantida, isticmaalayaashu waa inay doortaan hadba sida ay u baahan yihiin marka ay iibsanayaan muraayadaha LED-ka ee midabka buuxa ee meel yar, waana inaysan si indho la'aan ah u raacin isbeddelka.
