Bandhigyada LED-ka ayaa Sharaxay: Sida ay u shaqeeyaan iyo sababta ay muhiim u tahay

Waa maxay Muujinta LED?

Muujiye LED ah, oo gaabanMuujinta Diode-ka Iftiimaysa, waa qalab elektaroonik ah oo ka samaysan nalal yaryar oo iftiimaya marka ay korontodu dhex marayso, samaynaysa sawiro ama qoraal. Nalalka LED-yada waxaa lagu habeeyaa shabaqyo, LED kastana si gaar ah ayaa loo dami karaa ama loo dami karaa si loo muujiyo muuqaallada la rabo.

Bandhigyada LED-ka ayaa si weyn loogu isticmaalaa gudahacalaamada dhijitaalka ah, sabuuradaha, boorarka xayaysiinta, iyo qaar kaloo badan. Aad bay u adkeysanayaan, u adkeysanayaan saameynta iyo gariirka, waxayna awood u leeyihiin inay u adkeystaan ​​xaaladaha cimilada adag, isbedbedelka heerkulka, iyo qoyaanka. Tani waxay ka dhigaysaa inay ku habboon yihiin jawiga gudaha iyo dibadda labadaba.

Si ka duwan tignoolajiyada soo bandhigida dhaqameed sidaLCD (Muuqaal Crystal ah oo dareere ah) or OLED (Organic Light-Emitting Diode), Bandhigyada LED waxay abuuraan iftiin u gaar ah oo uma baahna iftiin dambe. Tilmaamahan gaarka ah ayaa siinaya iyagadhalaal sare, hufnaanta tamarta, iyo cimriga dheer.

Sidee bay u Shaqeeyaan Bandhigyada LED?

Aynu daaha ka qaadno sayniska ka dambeeya bandhigyada LED! Shaashadahani waxay isticmaalaan nalalka yar yar ee loo yaqaanDiodes iftiin-bixiya (LEDs)oo ka samaysan walxaha semiconductor. Marka hadda uu dhex socdo, tamarta ayaa lagu sii daayaa qaab iftiin ah.

RGB:
Si loo abuuro muuqaal firfircoon, LED-yadu waxay isticmaalaan isku darka saddexda midab ee aasaasiga ah:Cas, Cagaar, iyo Buluug (RGB). Mid kasta oo LED ah ayaa soo saara mid ka mid ah midabadaas, iyo iyada oo la hagaajinayo xoojinta, bandhiggu wuxuu soo saaraa midabyo buuxa, taas oo keentay sawirro iyo qoraal dijital ah oo muuqda.

Dib-u-cusbooneysiinta heerka iyo heerka guud:

• Theheerka dib u cusboonaysiintawuxuu go'aamiyaa inta jeer ee soo-bandhigidda soo-bandhigidda, hubinta kala-guurka siman iyo yaraynta blushka dhaqdhaqaaqa.

• Theheerka jirwaa tirada fiimyada ee lagu muujiyay ilbidhiqsikiiba, oo muhiim u ah fiidyowga aan xuduud lahayn iyo dib-u-ciyaarista animation.

Xalinta & Pixel Pitch:

• Qaraarkawaa tirada guud ee pixels (tusaale, 1920×1080). Qaraarka sare = tayada sawirka wanaagsan.

• Muuqaalka Pixelwaa masaafada u dhaxaysa pixels. Dhererka yar wuxuu kordhiyaa cufnaanta pixel, hagaajinta tafatirka iyo afaynta.

Xakamaynta yar yar:
Microcontrollers waxay u dhaqmaan sida maskaxda bandhigyada LED. Waxay ka baaraandegaan calaamadaha nidaamka xakamaynta iyo darawalka ICs si loo hubiyo iftiinka saxda ah iyo xakamaynta midabka.

Isdhexgalka Nidaamka Xakamaynta:
Nidaamka xakamaynta wuxuu u shaqeeyaa sidii xarunta taliska, isagoo isticmaalaya software si uu ula xiriiro microcontrollers. Tani waxay awoodkala-guurka aan kala go' lahayn ee u dhexeeya sawirrada, fiidyaha, iyo nuxurka is-dhexgalka, Maareynta fog, cusbooneysiinta firfircoon, iyo ku habboonaanta aaladaha dibadda iyo shabakadaha.

Noocyada Bandhigyada LED

Bandhigyada LED waxay ku yimaadaan qaabab badan si ay u daboolaan baahiyo kala duwan:

• Darbiyada Fiidiyowga LED- Baallayaal badan oo la isku daray oo isku dhafan shaashad weyn oo aan toos ahayn, oo ku habboon goobaha, qolalka xakamaynta, iyo tafaariiqda.

• Boodhadhka Bilaha LED-ka & Calaamadaha- Bandhigyo dhalaalaya oo isbarbar dhig sarreeya oo loo isticmaalo muuqaallada magaalada iyo waddooyinka waaweyn ee xayeysiinta.

• LED TV-yada & Kormeerayaasha- Soo bandhig muuqaalo fiiqan, midabyo firfircoon, iyo waxtarka tamarta.

• Bandhigyada LED-ka qaloocan- Waxaa loo qaabeeyey in lagu jaangooyo qallooca dabiiciga ah ee isha bini'aadamka, ee loo isticmaalo ciyaaraha, shineemooyinka, iyo bandhigyada.

• Bandhigyada LED-ka dabacsan-Daree naqshadaha qaloocan ama duuban iyadoo la ilaalinayo daahfurnaanta, inta badan loo isticmaalo tafaariiqda, bandhigyada, iyo matxafyada.

• Bandhigyada LED-ka Micro- U isticmaal chips-ka yar-yar ee iftiinka iftiinka sare, isbarbardhigga, iyo xallinta, oo ku habboon TV-yada, AR, iyo VR.

• Bandhigyada LED-ka ee is-dhexgalka- Ka jawaab taabasho ama dhaqdhaqaaqyo, oo si weyn loogu isticmaalo waxbarashada, tafaariiqda, iyo bandhigyada waayo-aragnimada quusta ah.

Faa'iidooyinka Bandhigyada LED

• Waxtarka Tamarta- LED-yadu waxay u beddelaan ku dhawaad ​​dhammaan tamarta iftiinka, iyagoo yareynaya isticmaalka tamarta.

• Cimri dheer- Naqshad adag oo gobolka ah ayaa hubisa adkeysiga iyo kharashka dayactirka hooseeya.

• Iftiimin Sare & Hufnaan- Muuqaalo qallafsan, xitaa meelaha dhalaalaya.

• Naqshad dabacsan- Waxaa lagu beddeli karaa qaabab qalloocan, laalaaban, ama qaabab aan caadi ahayn.

• Eco-saaxiibtinimo- Mercury-free, tamar-ku-ool ah, oo waara.

SMD vs. DIP

• SMD (Aaladda Dusha-Dusha):LEDs yaryar, khafiif ah oo leh dhalaal sare, xaglo daawasho oo ballaadhan, iyo cufnaanta pixel sare-ku habboonbandhigyo heer sare ah oo gudaha ah.

• DIP (Xirmada Labada-line):LEDs cylindrical ka weyn, aad u waara oo ku fiicanbandhigyada dibadda.

Doorashadu waxay ku xiran tahay codsiga: SMD gudaha gudaha, DIP ee dibadda.

LED vs LCD

• Muujinta LED:Isticmaal nalalka LED-yada si aad toos ugu iftiimiso shaashadaha ("toos-iftiin" ama "LED-array" buuxa).

• Muqaal LCD:Iskood ha shidin iftiin oo u baahan nalka dambe (tusaale, CCFL).

Bandhigyada LED waadhuuban, dabacsanaan badan, dhalaalaya, oo leh kala duwanaansho wanaagsan iyo kala duwanaansho midab oo ballaadhan. LCD-yada, in kasta oo ay ka badan yihiin, haddana waxay soo bandhigi karaan waxqabad wanaagsan, gaar ahaan tignoolajiyada sare ee IPS.
