Qhov refresh npaum li cas yog qhov zoo dua, 1920Hz lossis 3840Hz?

Qhov refresh npaum li cas yog qhov zoo dua, 1920Hz lossis 3840Hz?

 

 

 

 

Lub refresh npaum li cas ntawm LED zaub yog hais txog tus naj npawb ntawm lub sij hawm cov zaub screen rov qab los ntawm cov zaub screen ib ob, thiab chav tsev yog Hz (hertz). Lub refresh npaum li cas yog ib qho tseem ceeb qhia tau hais tias lub LED zaub screen yog ruaj khov thiab tsis flicker. Qhov siab dua qhov refresh npaum li cas ntawm LED zaub, qhov ruaj khov ntawm daim duab zaub, qhov me dua qhov pom kev flicker, thiab kev tiv thaiv qhov muag zoo dua.

 

Thaum siv cov chips tsav tsheb zoo tib yam, tus nqi tshiab tuaj yeem ncav cuag 960Hz, thaum siv dual latch tsav tsheb chips tuaj yeem txhim kho tus nqi tshiab ntawm cov lus qhia LED, thiab kev siv high-txhais high-end PWM tsav chips tuaj yeem ua rau tus nqi refresh. ntawm LED zaub ncav cuag 3840Hz.

 

Ntev npaum li qhov refresh npaum li cas ntawm LED zaub yog siab dua 960Hz, tib neeg lub qhov muag yog qhov tseem ceeb indistinguishable. Cov xim puv xim LED zaub screen ntawm cov txhuam hniav siab thiab cov txhuam hniav dav dav yog yuav luag tsis pom qhov muag liab qab thaum ua yeeb yaj kiab thiab duab, tab sis nws tuaj yeem paub qhov txawv ntawm kev tua nrog cov xov tooj ntawm tes thiab cov koob yees duab siab thiab cov khoom siv yees duab.

 

Lub vijtsam ntawm cov txhuam hniav dav dav yuav muaj dej ripples thaum thaij duab nrog lub xov tooj ntawm tes, thiab daim duab yuav zoo li nws yog flickering, thaum lub vijtsam ntawm txhuam siab yuav tsis muaj dej ripples.

 

Ntau npaum li cas yog qhov tsim nyog refresh npaum li cas ntawm LED zaub, nws tsuas yog nyob ntawm kev siv lub vijtsam thiab kev siv ib puag ncig. Yog tias nws yog ib qho xim LED nyob sab hauv tsev, nws tuaj yeem ua tau raws li qhov xav tau nrog 1920Hz (txhuam txhuam), yog tias koj xav siv kev yees duab thiab yees duab, ces nws raug nquahu kom siv 3840Hz siab txhuam.

 

Feem ntau, tsuas yog thaum tus nqi refresh ntau dua 2 npaug ntawm lub kaw lus ceev ntawm lub koob yees duab, LED zaub yuav tsis tshwm dej ripples. Ntawm qhov kev kaw dav dav ntawm 1/2000 thib ob ntawm lub koob yees duab, ze li ntawm 1000 refresh tus nqi ntawm tus neeg tsav tsheb sib tsoo zoo tib yam IC thiab 1920Hz refresh tus nqi ntawm tus tsav tsheb dual-latch IC tsis txaus kom tsis txhob muaj dej ripples, thiab tsuas yog cov high-definition high-end PWM tsav tsheb IC nrog tus nqi tshiab ntawm ntau dua 3840Hz tuaj yeem ua kom ntseeg tau tias LED zaub tsis tshwm sim dej ripples thaum thaij duab.

 

Niaj hnub no, tus ncej hloov pauv ntawm cov yeeb yaj kiab feem ntau yog 24Hz, uas txhais tau hais tias tsuas muaj 24 thav duab hauv 1 thib ob. Muab 24Hz ncej tus nqi yeeb yaj kiab rau ntawm LED zaub nrog 3840Hz refresh npaum li cas, 3840/24=160 zaug, uas yog, txhua tus ncej ntawm cov yeeb yaj kiab tau rov qab los ntawm cov zaub 160 zaug. Nrog rau qhov kev hloov tshiab no, tib neeg lub qhov muag tsis tuaj yeem pom qhov flickering ntawm daim duab, yog li cov zaub yog smoother thiab clearer.
