1. LEDs yog lub hauv paus ntsiab lus txiav txim siab qhov muag pom kev ua tau zoo ntawm tag nrho lub vijtsam, cuam tshuam ncaj qha rau cov neeg saib kev xaav ntawm cov zaub.
2. LEDs yog cov khoom siv tseem ceeb tshaj plaws uas siv nyob rau hauv tag nrho -xim npo, nrog ntau txhiab txog kaum txhiab tus LEDs siv ib square meter.
3. LEDs suav txog qhov loj tshaj plaws ntawm cov nqi tag nrho ntawm lub vijtsam zaub, xws li 30% txog 70%.
LEDs yog qhov tseem ceeb tshaj plaws ntawm tag nrho cov khoom siv ntawm tag nrho -xim LED zaub. Qhov zoo ntawm LEDs txiav txim siab ntau tshaj 50% ntawm tag nrho cov zoo ntawm cov zaub screen. Qhov zoo thiab qhov tsis zoo ntawm LEDs tshwj xeeb tsim los rau tag nrho - xim LED cov lus tuaj yeem raug sau tseg rau hauv tsib lub ntsiab lus tseem ceeb hauv qab no:
Ua ntej, Brightness
LED ci ntsa iab yog qhov tseem ceeb ntawm kev txiav txim siab qhov ci ntawm qhov screen. Qhov siab dua qhov ci ntsa iab ntawm LED, qhov ntau dua cov npoo tam sim no, uas muaj txiaj ntsig zoo rau kev txuag hluav taws xob thiab tswj kev ruaj ntseg LED. LEDs muaj qhov sib txawv ntawm qhov pom; muab lub teeb ci ruaj khov, lub kaum sab xis me me ua rau lub teeb ci dua, tab sis pom lub kaum sab xis me dua rau lub vijtsam zaub. Feem ntau, 100-degree LEDs yuav tsum raug xaiv los xyuas kom meej lub kaum sab xis pom txaus rau lub vijtsam zaub. Rau cov ntxaij vab tshaus nrog cov pixel sib txawv thiab saib qhov nrug, qhov sib npaug yuav tsum pom ntawm qhov ci, lub kaum sab xis, thiab tus nqi.
Thib ob, Failure Rate
Txij li tag nrho - xim zaub screen yog tsim los ntawm kaum tawm txhiab lossis txawm ntau pua txhiab pixels uas muaj cov xim liab, ntsuab, thiab xiav LEDs, qhov tsis ua tiav ntawm cov xim LED yuav cuam tshuam rau tag nrho cov kev pom ntawm lub vijtsam. Feem ntau, raws li kev lag luam kev lag luam, qhov ua tsis tiav ntawm qhov pib ntawm LED teeb pom kev sib dhos rau 72 teev ntawm kev laus ua ntej xa khoom yuav tsum tsis pub tshaj 0.03% (xa mus rau qhov ua tsis tiav los ntawm LED khoom nws tus kheej).
Thib peb, Attenuation yam ntxwv
Liab, ntsuab, thiab xiav LEDs txhua tus muaj cov yam ntxwv ntawm kev ci ntsa iab nrog rau lub sijhawm ua haujlwm. Qhov zoo ntawm LED nti, qhov zoo ntawm cov khoom siv pabcuam, thiab qib ntawm kev ntim tshuab txiav txim siab qhov txo qis ntawm LEDs. Feem ntau, tom qab 1000 teev ntawm kev teeb pom kev txuas ntxiv ntawm 20 mA ntawm chav tsev kub, qhov attenuation ntawm LEDs liab yuav tsum tsawg dua 10%, thiab qhov attenuation ntawm xiav thiab ntsuab LEDs yuav tsum tsawg dua 15%. Qhov sib xws ntawm liab, ntsuab, thiab xiav attenuation zoo heev cuam tshuam rau qhov dawb tshuav ntawm tag nrho -xim LED zaub yav tom ntej, thiab yog li cuam tshuam rau cov zaub fidelity ntawm lub vijtsam. Plaub, Anti- muaj peev xwm zoo li qub
LEDs yog cov khoom siv semiconductor thiab rhiab rau hluav taws xob zoo li qub, uas tuaj yeem ua rau electrostatic paug tsis ua haujlwm. Yog li ntawd, kev tiv thaiv - muaj peev xwm zoo li qub yog qhov tseem ceeb rau lub neej ntawm lub vijtsam zaub. Feem ntau, tib neeg lub cev qauv electrostatic tawm tsis ua hauj lwm voltage ntawm LEDs yuav tsum tsis txhob qis dua 2000V.
Thib tsib, Kev Sib Raug Zoo
Ib daim ntawv qhia tag nrho -xim LED zaub yog tsim los ntawm suav tsis txheeb pixels ua los ntawm liab, ntsuab, thiab xiav LEDs. Qhov sib xws ntawm qhov ci ntsa iab thiab wavelength ntawm txhua xim LED txiav txim siab qhov ci ci sib xws, qhov sib npaug ntawm cov xim dawb, thiab chromaticity sib xws ntawm tag nrho cov zaub screen. Feem ntau, cov chaw tsim khoom lag luam xav tau cov khoom lag luam los muab cov LEDs nrog lub wavelength ntawm 5nm thiab qhov ci ci ntawm 1: 1.3. Cov kev qhia tshwj xeeb no tuaj yeem ua tiav los ntawm cov khoom lag luam los ntawm kev txheeb xyuas siv lub spectroradiometer. Voltage sib xws feem ntau tsis tas yuav tsum tau.
