LED zaub brightness tuaj yeem kho tau zoo ntawm software. Lub hauv paus ntsiab lus yog hloov PWM lub luag haujlwm lub voj voog ntawm tus neeg tsav tsheb, ua ke nrog kev hloov kho tam sim no thiab kev hloov kho tsis siv neeg, kom ua tau raws li qhov xav tau ntawm cov xwm txheej sib txawv thiab tsis txhob muaj teeb meem lub teeb. Nov yog cov lus piav qhia ntxaws:
Lub hauv paus ntsiab lus thiab kev ua tau zoo ntawm Software Brightness Kho
Tus neeg siv interface thiab kev tswj hwm hauv qab: Software brightness hloov tau tiav los ntawm tus neeg siv interface. Tom qab tus neeg siv nkag mus rau cov lus txib, lub software hloov PWM (Pulse Width Modulation) lub voj voog ntawm LED zaub tsav tsheb. Piv txwv li, tam sim no software brightness hloov yog feem ntau adjustable nyob rau hauv 256 theem. Los ntawm kev kho lub voj voog lub luag haujlwm, qhov feem ntawm LED emission lub sij hawm tuaj yeem tswj tau qhov tseeb, yog li ua tiav qhov ci ci.
Kev ua tau zoo ntawm kev hloov kho: Software brightness hloov tau zoo. Vim tias kev hloov pauv PWM lub voj voog ua haujlwm ncaj qha cuam tshuam rau LED lub luminous siv, thiab txoj kev no tsim nyog rau kev tswj hwm digital, sib piv cov xwm txheej tam sim no uas lub khoos phis tawj - muab cov ntsiab lus LED tso saib ua tau raws li qhov yuav tsum tau muaj qhov ci ntawm cov xwm txheej sib txawv.
Lwm yam cuam tshuam rau LED zaub Brightness thiab hloov txoj kev
Hloov Tam Sim No: Kev ci ntsa iab tuaj yeem hloov kho los ntawm kev hloov pauv tam sim no ntws los ntawm LED zaub. Feem ntau, qhov tso cai txuas ntxiv ua haujlwm tam sim no ntawm LED yog li 20mA. Tsuas yog cov LEDs liab, uas nthuav tawm saturation, lub ci ci ntawm lwm cov LEDs yog qhov sib piv rau tam sim no. Txawm li cas los xij, txoj kev no tsis tshua siv ib leeg hauv kev siv tswv yim vim tias kev hloov pauv tam sim no tuaj yeem cuam tshuam rau lub neej thiab kev ruaj ntseg ntawm LEDs.
Pulse Width Modulation (PWM) greyscale tswj: Txoj kev no siv qhov pom kev inertia ntawm tib neeg lub qhov muag, ua tiav greyscale tswj los ntawm kev hloov pauv qhov dav ntawm lub teeb mem tes (ie, lub luag haujlwm voj voog). Tsuav tus nqi refresh yog siab txaus, tib neeg lub qhov muag yuav tsis pom pixel flickering. Vim tias PWM yog qhov tsim nyog rau kev tswj hwm digital, yuav luag txhua qhov LED qhia tam sim no siv cov qauv no los tswj cov nplai grey, yog li cuam tshuam rau kev ua haujlwm ci ntsa iab.
LED zaub Brightness yuav tsum tau thiab kho nyob rau hauv txawv scenarios
Sab Nraud Tag Nrho- Xim LED Zaub: Ci ntsa iab yuav tsum ncav cuag yam tsawg 1500 cd / m² kom ntseeg tau tias kev ua haujlwm ib txwm muaj; txwv tsis pub, qhov ci tsis txaus yuav tiv thaiv cov duab tso saib. Txawm li cas los xij, ntau lub teeb pom kev sab nraum zoov tam sim no tshaj 5000 cd / m², muab kev ua si zoo rau nruab hnub tab sis ua rau muaj teeb meem loj heev thaum hmo ntuj, cuam tshuam cov neeg nyob ze.
Qhov Tseem Ceeb ntawm Kev Kho Kom Zoo Dua: Txhawm rau kom tsis txhob muaj teeb meem lub teeb thiab ua tau raws li kev xav tau ntawm lub sijhawm sib txawv, nws yog qhov tsim nyog los kho qhov ci ntawm LED zaub. Los ntawm kev sib xyaw ua ke ntawm software thiab kev ua lag luam, cov duab ci tuaj yeem raug txiav lossis hloov kho raws li lub teeb pom kev zoo. Piv txwv li, qhov kev hloov kho tsis siv neeg tuaj yeem kho qhov ci ntsa iab raws li lub teeb pom kev zoo, thaum kev hloov kho phau ntawv tso cai rau cov neeg siv los hloov kho kom zoo raws li cov kev xav tau tshwj xeeb.
Chaw tsim tshuaj paus kev cob qhia thiab cov neeg siv khoom lag luam: Feem ntau, tom qab qhov project tiav lawm, cov chaw tsim khoom yuav muab kev cob qhia software tshwj xeeb los pab cov neeg siv khoom sai sai pib nrog kev tswj hwm thiab kev ua haujlwm. Qhov no pab cov neeg siv khoom zoo dua siv lub software lub teeb ci kev ua haujlwm, kho cov duab ci ntsa iab raws li qhov xav tau tiag tiag ntawm qhov xwm txheej, txhim kho cov neeg siv kev paub, thiab txo cov teeb meem tshwm sim los ntawm qhov tsis zoo ntawm qhov ci.
