LCD polarizer heev tsub kom cov zaub Backlighting efficiency

Apr 01, 2017
UCLA engineers tau tsim ib tug lub tswvyim rau ntxawm thiab "ub" zog los ntawm LCD cov ntxaij vab tshaus. Ua-nyob rau hauv photovoltaic polarizers tso cai rau lawv mus hloov ambient lub teeb, tshav ntuj thiab lawv tus kheej backlight rau hauv hluav taws xob.

LCDs ua hauj lwm los ntawm kev siv ob polarized los xij uas yuav cia tsuas ib qhov nqi ntawm ib tug ntaus backlight kis tau los ntawm. Me me quav ua kua siv lead ua molecules yog sandwiched ntawm ob polarizers, thiab cov muaju yuav hloov los ntawm me me transistors ua raws li tej teeb li qub. Manipulating txhua lub teeb valve, los yog pixel, cia ib qhov nqi ntawm cov backlight khiav; tsheej lab ntawm xws pixels ua ke los mus tsim cov dluab nyob LCDs.

Lub UCLA Engineering pab tsim ib tug tshiab hom ntawm lub zog-ntxawm polarizer rau LCDs hu ua ib tug polarizing organic photovoltaic, uas muaj peev xwm muaj feem boost tus muaj nuj nqi ntawm ib tug LCD los ntawm ua hauj lwm ib txhij raws li ib tug polarizer, ib tug photovoltaic ntaus ntawv thiab ib tug ambient lub teeb los yog tshav ntuj photovoltaic vaj huam sib luag.

UCLA soj ntsuam Yang Yang hais tias nws ntseeg hais tias cov pab pawg neeg lub invention yuav muaj ib tug kev ua si hloov tseem ceeb nyob rau hauv lub teb ntawm LCD Backlighting efficiency. "Cov polarizers kuj yuav siv tau raws li ib txwm hnub ci hlwb sau sab hauv tsev los yog sab nraum zoov teeb. Yog li ntawd tom ntej no lub sij hawm koj nyob rau lub puam, koj yuav them koj iPhone ntawm tshav ntuj," Yang Yang hais tias.

Ntawm tus taw tes ntawm view ntawm lub zog siv, tam sim no LCD polarizers yog inefficient, tus neeg tshawb fawb hais tias. Ib tug ntaus backlight muaj peev xwm haus 80 rau 90 feem pua ntawm tus dais lub hwj chim. Tab sis raws li ntau li ntau 75 feem pua ntawm lub teeb generated yog poob los ntawm lub polarizers. Ib tug polarizing organic photovoltaic LCD yuav rov qab ntau npaum li cas ntawm cov uas tsis siv lub zog.

"Lub polarizing organic photovoltaic cell pom los ntawm cov xibfwb Yang txoj kev tshawb fawb pab pawg neeg yuav muaj feem sau 75 feem pua ntawm cov sij hawm photons los ntawm LCD backlight thiab tig lawv rov qab mus rau hauv hluav taws xob," hais tias Youssry Botros, qhov kev pab cuam tus thawj coj rau lub Intel no-piv Academic Research Office, uas txaus siab rau cov kev tshawb fawb . "Lub zog kev koom tes ntawm no pab pawg neeg ntawm UCLA Engineering thiab lwm yam sab saum toj pawg tau coj mus rau siab dua cell tshem, ua lub peev xwm rau ntxawm lub zog. Qhov no mus kom ze yog nthuav nyob rau hauv nws tus kheej txoj cai thiab nyob rau tib lub sij hawm synergetic nrog ob peb lwm yam tej yaam num peb pab nyiaj txiag los ntawm lub Intel no-piv Academic Research Office. "

Cov pab pawg neeg txoj kev tshawb fawb tshawb pom yog tam sim no muaj nyob rau hauv lub hauv internet tsab ntawm phau ntawv journal Advanced ntaub ntawv thiab yuav tsum luam tawm nyob rau hauv ib tug dabtsi ntsiv sau qhov teeb meem ntawm phau ntawv journal.
