Markaad dooranayso bandhig cusub, ha ahaato telefiishanka, kormeeraha, ama calaamada dhijitaalka ah, mid ka mid ah jaahwareerka ugu badan ayaa ah go'aaminta u dhexeeya LED iyo tignoolajiyada LCD. Labada erey ayaa inta badan la kulma adduunka teknoolojiyadda, laakiin maxay dhab ahaantii ula jeedaan? Fahamka farqiga u dhexeeya LED iyo LCD waxay kaa caawin kartaa inaad samayso go'aan xog ogaal ah oo ku saabsan tignoolajiyada soo bandhigida ee ku habboon baahiyahaaga.
Fahamka tignoolajiyada LED iyo LCD
Si loo bilaabo, waxaa muhiim ah in la caddeeyo in "LED" (Light Emitting Diode) iyo "LCD" (Liquid Crystal Display) aysan ahayn tignoolajiyada kala duwan. Dhab ahaantii, inta badan way wada shaqeeyaan. Waa kan sida:
- LCDMuujinta LCD waxay isticmaashaa kiristaalo dareere ah si ay u xakamayso iftiinka oo ay u abuurto sawirro shaashadda. Si kastaba ha ahaatee, kiriimyadani ma soo saaraan iftiin iskood ah. Taa baddalkeeda, waxay u baahan yihiin iftiin dambe si ay u iftiimiyaan bandhigga.
- LED: LED waxa loola jeedaa nooca iftiinka dambe ee loo isticmaalo bandhigyada LCD. LCD-yada dhaqameedku waxay u isticmaalaan CCFL (lambaska fluorescent cathode qabow) ee iftiinka dambe, halka bandhigyada LED ay adeegsadaan shumacyo iftiin leh. Iftiinka dambe ee LED-ka ayaa ah waxa LED-ka siinaya inay soo bandhigaan magacooda.
Nuxur ahaan, "muujinta LED" dhab ahaantii waa "muujinta LCD-daba-yar ee LED." Farqiga ayaa ku jira nooca iftiinka dambe ee la isticmaalo.
Farqiga Muhiimka ah ee u dhexeeya LED iyo LCD
- Farsamada iftiinka dambe:
- LCD (Nalalka dambe ee CCFL)LCD-yadii hore waxay isticmaaleen CCFL-yada, kuwaas oo siinaya iftiin isku mid ah shaashadda laakiin waxay ahaayeen kuwo tamar yar leh oo ka culus.
- LED (Iftiinka dambe ee LED): LCD-yada casriga ah ee leh iftiinka dambe ee LED waxay bixiyaan nalal badan oo gudaha ah, taas oo awood u siinaysa isbarbardhigga iyo waxtarka tamarta. Nalalka LED-yada waxaa lagu habayn karaa qaab-dhismeedyo-iftiin ama hab-buuxa, taasoo u oggolaanaysa in si sax ah loo xakameeyo iftiinka.
- Tayada Sawirka:
- LCDLCD-yada caadiga ah ee CCFL-backlit LCDs waxay bixiyaan dhalaal wanaagsan laakiin inta badan waxay la halgamaan madow qoto dheer iyo isbarbardhigga sare sababtoo ah xaddidnaanta iftiinka dambe.
- LED: Bandhigyada LED-ka ee dib u iftiiminaya waxay bixiyaan kala duwanaansho heer sare ah, madow qoto dheer, iyo midabyo firfircoon, iyada oo ay ugu wacan tahay awoodda lagu khafiifiyo ama iftiimiyo meelo gaar ah oo shaashadda ah (farsamo loo yaqaan dimming local).
- Waxtarka Tamarta:
- LCD: Bandhigyada CCFL-backlit waxay cunaan awood badan sababtoo ah iftiinkooda oo yar iyo awood la'aanta inay toosiyaan dhalaalka si firfircoon.
- LEDMuujinta LED-yada ayaa ah kuwo tamar badan leh, maadaama ay isticmaalaan awood yar waxayna hagaajin karaan dhalaalka si firfircoon iyagoo ku saleysan nuxurka la soo bandhigay.
- Naqshadaynta Slimmer:
- LCDLCD-yada caaddiga ah ee CCFL-dab shid ayaa ka sii mug weyn sababtoo ah tubooyinka iftiinka dambe ee waaweyn.
- LED: Cabbirka is haysta ee LED-yada ayaa u oggolaanaya bandhigyo khafiif ah oo khafiif ah, taas oo ka dhigaysa mid ku habboon naqshadaha casriga ah ee casriga ah.
- Saxnaanta Midabka iyo Iftiinka:
- LCD: Bandhigyada CCFL-dab-yar waxay guud ahaan bixiyaan saxnaanta midabka wanaagsan laakiin waxaa laga yaabaa inay ka gaabiyaan bixinta sawirro dhalaalaya oo firfircoon.
- LED: LED-ku wuxuu muujinayaa heer sare xagga saxnaanta midabka iyo dhalaalka, gaar ahaan kuwa leh tignoolajiyada horumarsan sida dhibcaha quantum ama iftiinka dambe ee habaysan.
- Cimriga:
- LCD: Bandhigyada CCFL-dabaalku waxay leeyihiin cimri gaaban sababtoo ah tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib ah.
- LED: Bandhigyada LED-ka waxay leeyihiin cimri dheer, maadaama LED-yadu ay yihiin kuwo aad u adkeysi badan oo ilaaliya dhalaalkooda muddo dheer.
Codsiyada iyo Ku-habboonaanta
- Madadaalada Guriga: Kuwa raadinaya muuqaal tayo sare leh oo leh midabyo qani ah iyo kala duwanaansho qoto dheer, bandhigyada LED-backlit ayaa ah doorashada la doorbido. Waxaa si weyn loogu isticmaalaa telefishinada casriga ah iyo kormeerayaasha, iyagoo siinaya waayo-aragnimo daawasho leh oo loogu talagalay filimada, ciyaaraha, iyo baahinta.
- Isticmaalka Xirfadlayaasha: Goobaha ay saxnaanta midabka iyo dhalaalku muhiim u yihiin, sida naqshadaynta garaafyada, tafatirka muuqaalka, iyo calaamadaynta dhijitaalka ah, bandhigyada LED-ku waxay bixiyaan saxnaanta iyo caddaynta loo baahan yahay.
- Fursadaha Miisaaniyad-Saaxiibka ah: Haddii kharashku yahay welwelka aasaasiga ah, bandhigyada LCD-ka-soo-jireenka ah ee CCFL-daba shid ayaa laga yaabaa in wali laga helo dhibcaha qiimaha hoose, inkastoo laga yaabo in waxqabadkoodu aanu la mid ahayn moodooyinka LED-backlit.
Gabagabo: Keebaa Wanagsan?
Doorashada u dhaxaysa LED iyo LCD waxay inta badan ku xiran tahay waxa aad ku qiimeyso bandhigga. Haddii aad mudnaanta siiso tayada sawirka sare, hufnaanta tamarta, iyo naqshadda casriga ah, bandhigga LED-backlit waa guusha cad. Bandhigyadani waxay bixiyaan sida ugu fiican ee labadaba: waxqabadka la isku halayn karo ee tiknoolajiyada LCD oo ay weheliso faa'iidooyinka iftiinka iftiinka LED.
Si kastaba ha noqotee, haddii aad ku jirto miisaaniyad adag ama aad leedahay shuruudo gaar ah oo aan u baahnayn tignoolajiyada ugu dambeysay, LCD-ga weyn ee leh iftiinka dambe ee CCFL ayaa ku filnaan kara. Taasi waxay tidhi, sida tignoolajiyada horumarsan, bandhigyada LED waxay noqdeen kuwo la heli karo oo la awoodi karo, taasoo ka dhigaysa ikhtiyaarka ikhtiyaarka macaamiisha iyo xirfadlayaasha intooda badan.
Dagaalka LED vs LCD, guusha dhabta ah waa daawadaha, kaas oo ka faa'iideysanaya waayo-aragnimada muuqaalka ah ee soo kordheysa ee ay wadaan tignoolajiyada bandhigga cusub.
