Waa maxay nalalka LED? noocyada nalalka

Saarayaasha ee wax soosaarka telefishanka si joogto barasho users la teknoolajiyada cusub in kor loo qaado tayada image of gudbinta. Sida lagu heshiisiinta ee shaashadaha TV iyo xubno LED ayaa muddo dheer addoonsada shirkadaha ugu weyn. Recently, il siyasad dhalaalaya oo jilicsan ayaa sidoo kale maray qaab mobile. Qiimee mudnaanta go'aan noocan oo kale ah awoodo iyo users of nalalka dhaqanka ku salaysan Kokes, laakiin, dabcan, ay looks ugu soo jiidashada badan backlight telefishinada LED-screens. The more sidaas maxaa yeelay waxa ay dhameystirta iyo markeeda kale farsmada heerka sare ah loo isticmaalo horumarinta farsamada this.

qalabka iftiiminta

In abuurka modules si ay u hirgeliyaan backlight ee LED-Arrays waxaa loo isticmaalaa oo ka koobnaan kartaa xubno caddaan LED midabka kala duwan ama luminescence, sida RGB. Guddiga ayaa loogu talagalay in lagu qalabeeyo furta oo si gaar ah loogu talagalay in ay dhex galaan model side qalab gaar ah. Caadi ahaan, dhinaca bidix ee Xidhiidhiyayaasha guddiga waxaa lagu abaabulaa, mid ka mid ah kaas oo bixiya Nuur awood LED a, halka kuwo kale ay loogu talagalay in lagu xakameeyo qaabeynta hawlgalka ay. Sidoo kale, waayo, modules LED isticmaali darawalka gaarka ah, shaqo ee kaas oo la xidhiidha dirato.

In foomka dhammeeyey LED strip ka kooban yahay taxane ah oo laambadaheeda Ghadafi oo ku xiran yihiin kooxo ka mid ah 3 gogo '. Dhab ahaantii, saarayaasha ha ku talinaynaa faragelin qalabka cajalado sida, laakiin waxaa laga yaabaa in jir ahaan soo gaabisay ama, taas bedelkeeda, sameeyo qalab dheer haddii la doonayo. Sidoo kale, unit screen LED-backlight waxay siisaa awood ay ku qabsato dhalaalka, uu xusay in laga bilaabo siman oo ku qalabeysan yahay ilaalinta danab.

Qoondaynta nooca goob backlight

Waxaa jira labo siyaabood si ay u dhexgalaan Nuur LED - si toos ah iyo dhammaadka. qaabeynta ugu horeeya ee u baahan in ay soo diyaariyeen laga dhisi doonaa dambeeya guddiga crystal dareere ah. Habka labaad kuu ogolaanayaa inaad si ay u abuuraan screens darfaha aad u dhuuban oo waxaa la yiraahdaa Edge-LED. Xaaladdan oo kale, meelaynta cajalad ku wareegsan wareega ah ee dhinaca gudaha ee shaashadda. Sayidka qaybinta direyska ah ee uu Kokes ku waa la fuliyay oo macneheedu yahay guddi oo la takhalusin dambeeya LCD ah - caadi ahaan noocan ah backlight LED-screen waxaa loo isticmaalaa horumarinta qalabka mobile. Dhaggan backlight toos muujinayaan natiijada tayo of luminescence, oo waxaa lagu gaarayaa by Tiro badan oo uu Kokes iyo sidoo kale dimming degaanka si loo yareeyo xariijimo midabka.

Codsiga of illuminator ee LED

macaamiisha ayaa celcelis ahaan ka heli kartaa technology this ee lagu daydo ee Sony telefishinada, LG iyo Samsung, iyo sidoo kale waxyaabaha Kodak iyo Nokia. Dabcan, Kokes ayaa noqday mid baahsan, laakiin waa in lagu daydo ee saarayaasha waxyaalahan waxaa loo arkay isbedel tayo jihada of hagaajinta tayada macaamiisha go'aankan ka. Mid ka mid ah dhibaatooyinka ugu waaweyn ee soo food by samaynta waa in la taageero waxqabadka screen oo leh sifooyin si mug leh u eego qorraxdu si toos ah. Sidoo kale, ee LED LED-backlight ayaa dhawaan soo hagaagtay marka la eego kordhinta farqiga. Haddii aan ka hadlo horumarka dhinaca dhismaha shaashadda, ka dibna waxaa jira hoos u muhiim ah in dhumucda darfaha, iyo sidoo kale waafaqsan yahay shaashad ballaaran. Laakiin sii dhibaato xallin. Kokes ku aadan awoodin in aad si buuxda u horumariyaan awooddooda in geeddi-socodka lagu soo bandhigeen warbixin. Si kastaba ha ahaatee, tani waxba uma looga hortago ka technology LED-Leexin CCFL-laambadood oo la tartami qarnigan cusub ee screens plasma.

saamaynta gargaarka

Module-ku salaysan dioska- light-emitting leeyihiin badan oo awoodooda si ay u bixiyaan saamaynta kala duwan. Marka marxaladdan oo ah horumarinta warshadaha technology si firfircoon la isticmaalayo laba xal stereoscopic. marka hore wuxuu bixiyaa kala fogaanta dhexdeena ah angular of fluxes shucaaca oo taageero ka saamayn diffraction ah. user The Oga saamaynta ee koorsada of daawashada adiga oo isticmaalaya koob ama iyaga oo aan, taasina waa, in hab holography. Saamaynta labaad waxaa ka mid ah barakaca ee ka daadanayo iska Ifto Yuuna oo soo bandhigtay nalalka LED-bandhigay xagga jidka Fundka ee layers dareere ah crystal. Isticmaalka technology this lagu dari karaa 2D iyo 3D-qaabab ka dib markii diinta ku haboon ama transcoding. Si kastaba ha ahaatee, oo ku saabsan isku-dar ah u suurtoobaan images saddex geesood ah oo ka backlights LED aan si habsami leh u socday.

Jaanqaadaan technology 3D

Waxaan ma dhihi karo in shaashadda la LED-backlit, waxaa jira dhibaatooyin halis soo wajahda format 3D, laakiin aragtida isitcmaalo daawadayaasha noocan oo kale ah "Sawirka" u baahan tahay koob gaar ah. Mid ka mid ah meelaha ugu wanaagsan ee horumarka this waa koob rikoodh. Tusaale ahaan, injineerada nVidia sii daayay koob 3D dhawr sano ka hor-shutter la lenses dareere ah crystal. Waayo, deflecting alwaaxdii saqafka haysay, iftiinka LED-backlight screen LCD siinayaa isticmaalka filtarrada kala fogaansho. Xaaladdan oo kale, dhibcood ayaa lagu fuliyaa iyada oo aan jir ah oo gaar ah, qaab cajalad. gashto gundhig ka kooban yahay isugu soo balaadhan oo ah translucent Arrays LED, oo Oga macluumaadka qalabka gacanta.

Faa'iidooyinka backlight ah

Marka loo eego fursadaha kale ee nalalka, uu Kokes si weyn loo hagaajiyo tayada screens telefishanka macaamiisha. Ugu horayn hagaagtay sifooyinka image si toos ah - tani waxa ay keentey in kordhaya dhalmo la barbardhigo iyo midabka. The processing spectrum midabka tayada sareeya bixisaa RGB-furta. Intaa waxaa dheer, LED-backlight isticmaalka kala duwan awood yar yahay. Oo gaari korontada yareynta isticmaalka ilaa 40% xaaladaha qaarkood. Sidoo kale xusid mudan waa wax macquul ah ee soo saara screens ultrathin, kaas oo waqti isku mid ah waxay leeyihiin miisaan yar.

ceebaha

Xubnaha telefishinada joogo la backlight LED dhaleeceeyay ay waxyeellada daran ee shucaaca buluug-buluug on indhaha. Sidoo kale buluug arkay "image" ugu in ay xumeeyaan dhalmo midabka dabiiciga ah. Si kastaba ha ahaatee, in qoraalkii ugu dambeeyey ee TV la sare -resolution screen LED-backlight ayaa ku dhowaad ma cilladaha sida. Laakiin waxaa jira dhibaatooyin la xiriira maareynta dhalaalka, taas oo wadnaha lug width isbedbeddelka. In goobaha sida, waxaad ka ogaan kartaa flicker shaashadda.

gunaanad

Si aad u taariikhda, ku dayashada TV qeybta la-technology LED waa bilaw. Iyadoo macaamiisha qiimeeyaan fursadaha iyo sharaf, oo waa inay awoodaan inay bixiyaan xal cusub. Waa in la ogaadaa in khasaaraha hawl hantiyeen LED LED-nalalka, isku qaldin dadka isticmaala qiimaha sare. Aqoonyahano badan, factor this waxaa loo arkaa caqabad weyn ku popularization ee technology. Si kastaba ha ahaatee, rajada ee uu Kokes ayaa weli rajo leh, sida ay qiimaha hoos u dhigi doontaa sida baahida kordhay. Barbaro ah in ay this iyo mid kale oo tayo leh oo la hagaajiyay, taasoo sii kordhisaa jiidashada of dalab.
