Uas yog zoo dua: IPS los yog AMOLED? Sib piv thiab nrov lub tswv yim

Ntawm UFW ntawm cov technologies siv nyob rau hauv qhov siv thiab ua qhia, mobile pab kiag li lawm, muab faib mus rau hauv AMOLED thiab LCD adherents lovers. Ob hom cov ntxaij vab tshaus raws li nyob rau hauv ntau yam raug hom kev kawm, thiab manufacturers feem ntau cov zoo ntawm xwb nws tus kheej txoj kev.

Yog li ntawd yog dab tsi qhov screen yog zoo dua - IPS los yog AMOLED? Puas muaj ib tug hnov li sib txawv ntawm ob technologies, thiab yog hais tias yog li ntawd, yog dab tsi?

LCD technology

LCD txhais tau tias ib tug LCD zaub. Nws reproduces xim nyob rau hauv ib tug txawv kiag li txoj kev tshaj lub AMOLED. Cov kua siv lead ua zaub teeb qhov chaw yog ib tug backlight. Backlight yuav ua tau ntau yam, uas tej yam zog, tab sis nws yog siv nyob rau hauv loj TVs.

Dawb tsis muaj nws tus kheej wavelength. Nws yog ib tug sib tov ntawm tag nrho cov lwm yam pom xim ntawm lub spectrum. Yog li, lub LCD backlight yuav tsum tau tsim ib tug xav txog tej yam lub teeb dawb li nraaj tau nyob rau hauv thiaj li yuav tau los ntawm nws ib tug txawv xim nyob rau hauv lub LCD caij. Feem ntau cov LCD qhia muaj ib tug xiav LED backlight, uas ntog on phosphorus thiab generates ze rau lub teeb dawb.

Qhov tiag nyuaj pib thaum lub teeb yog polarized thiab kis tau los ntawm tus siv lead ua. LCD caij yuav tig rau ntawm nws lub ces kaum sib txawv los ntawm kev hloov lub voltage thov thereto. Lub teeb ces kis tau los ntawm lwm cov polarization lim, offset los ntawm 90 ° nrog hwm mus rau tus thawj. Nws extinguishes nws, nyob ntawm seb lub kaum sab xis ntawm kev sib hloov. Tom qab ntawd, lub teeb kis tau los ntawm cov RGB-lim, txoj kev kom subpixels grouped ces mus rau lub pixels.

Tag nrho cov no yuav qhia tau tias lub LCD-zaub ntawm lwm yam uas tus nqi ntawm lub teeb los thaiv cov hlab lub illumination lub teeb thiab xim rau txhua pixel yog generated. Zoo li AMOLED, LCD-qhia tej zaum yuav ua kom nquag plias los yog passive matrix pab kiag li lawm.

AMOLED-technology

Muab zais nyob rau hauv lub title tseem ceeb tivthaiv cov ntxaij vab tshaus ntawm no hom - LED (LED). Electronics lovers paub txog tej no qhov muag ua ntej, tab sis nyob rau hauv cov zaub vaj huam sib luag yog dramatically txo kom tsawg thiab muab tso rau hauv daim ntawv ntawm cov xim liab, ntsuab thiab xiav pawg hais tias ua li ib tug tib pixel muaj peev xwm sawv ntawm displaying dawb thiab lwm yam xim. Lub layout ntawm cov subpixels zaum yuav ib nyuag hloov qhov kev kawm ntawm qhia.

Cov tsab ntawv O qhia ib tug organic. Muaj ib tug xov tooj ntawm nyias organic films muab tso rau nruab nrab ntawm cov LED conductors, emitting lub teeb thaum tam sim no tsev.

Thaum kawg, lub AM feem nyob rau hauv AMOLED tsa "active matrix", raws li txwv mus passive technology. Qhov no qhia li cas los tswj txhua LED OLED. Yuav kom tswj tau ib tug neeg pixel nyob rau hauv lub passive matrix yog siv kev circuits, tswj lub mov voltage rau cov yam kem los yog kab. Nws yog qeeb thiab insufficiently tseeb.
