Bandhigga tooska ah ee LED-ka ee yar ayaa ka awood badan LCD

Nalalka yaryar Horumarka ilaa hadda, iyadoo tiknoolajiyadda sii kordheysa ee qaan-gaartay, dhalaalkeeda sare, isbarbardhigga sare, midabka sare iyo astaamaha kale ayaa si tartiib tartiib ah loogu aqoonsaday macaamiisha. Si kastaba ha ahaatee, way adkayd in laga takhaluso aragtida khaldan ee ah in LED-ku si toos ah u soo bandhigo "macaamiisha korontada".

Haddaba, xaggee bay ka jirtaa aragtida khaldan ee ah in Led-ka YarIsticmaalka korontada ee sare wuxuu ka yimaadaa?

Dhinac, jajabyada LED-ka ee dhaqameedku waa kuwo waaweyn oo aan waxtar lahayn. Shaashadda LED-ka ee caadiga ah ee nolol maalmeedka weli waa bandhigga LED-ka ee SMD ee balastarrada waaweyn ee walxaha. Noocan bandhigga SMD wuxuu ka kooban yahay xirmo wanaagsan oo ah kuullo iftiin ah, jajabka iftiinka ee loo isticmaalo kuullada laambadda ayaa aad uga weyn jajabka Mini LED, hufnaanta iftiinka iyo hufnaanta kala-baxa kulaylkana aad bay u hooseysaa.

Chip-ka Mini LED-ka ee rogroga wuxuu leeyahay dhalaal iyo hufnaan iftiin badan marka loo eego chip-ka weyn ee loo isticmaalo SMD-ga dhaqameed (1010/1212/1515, iwm.); Sidaa darteed, xaaladahaas oo kale, Nalalka yaryar Isticmaalka awoodda jajabka rogrogmada ayaa sidoo kale hooseeya.

Dhanka kale, muraayadaha LED-ka ee bannaanka ka shaqeeya, waxay ka tagayaan aragti khaldan. Bandhigga tooska ah ee LED-ka ee gudaha lagu soo bandhigo ma uusan dheerayn, dareenka dhaqameed ee bandhigga tooska ah ee LED-kana wuxuu aad ugu badan yahay dibadda. Bandhigga guud ee gudaha, ha ahaado LCD ama LEDIftiinka 200-400nit ayaa ku filan, laakiin baahiyo ganacsi awgeed, dhalaalka ay u baahan tahay LED-ka dibadda ayaa tobanaan jeer ka sarreeya kan gudaha, isagoo gaaraya 8000 ama xitaa 10000nit, isticmaalka korontada si dabiici ah isku mid ma aha. Bedka shaashadda bandhigga gurigana waa tobanaan boqol oo jeer kan shaashadda gudaha, sidaa darteed LED-ku wuxuu ka tagayaa aragti khaldan oo ah in kuleylku uusan ahayn oo keliya mid daran, laakiin isticmaalka awoodda shaashadda oo dhan uu sidoo kale aad u sarreeyo.

Maxay kiristaalka dareeraha ahi u isticmaalaan awood ka badan aragtida?

Sababtoo ah LCD ma damin karo lakabka iftiinka dambe. Soo bandhigida kiristaalka dareeraha ah waxaa lagu gaaraa laba nidaam oo kala duwan: iftiinka dambe ayaa mas'uul ka ah bixinta dhalaalka, molecules-ka kiristaalka dareeraha ahna waxay xakameeyaan isbeddelka midabka, iftiinka iyo mugdiga iyagoo leexanaya. Sidaa darteed, ilaa inta LCD-ga la shido, iyadoon loo eegin shaashadda la soo bandhigayo, xitaa haddii ay tahay shaashad madow, lakabka iftiinka dambe had iyo jeer wuxuu ahaa mid dhalaalaya oo joogto ah, mana si xor ah loo hagaajin karo ama loo xiri karo.

Bandhigga tooska ah ee LED-ka waa mid is-iftiin leh oo ay keento chip-ka LED-ka, dhalaalka iyo midabka waxaa si toos ah u kaxeeya hadda iyo danab-ka. LED chip si loo gaaro, pixels madow iftiin hoose, isticmaalka awoodda oo hooseeya, pixels madow iftiin ma soo saaraan, isticmaal awood oo aan jirin.
