Yog vim li cas saib flickers

Yog hais tias nyob rau kaj ntug ntawm laij ib tug desktop nyob rau hauv tsev kov indicative ntawm cov kev ruaj ntseg thiab exceptional zauv peev xwm ntawm nws tus tswv, nyob rau hauv ob xyoo lawm, qhov teeb meem no tau radically hloov. Xyuas hauv computer thiab laptops tau ua raws li cov trappings ntawm lub neej niaj hnub, zoo li ib tug tsis siv neeg ntxuav tshuab los yog ib tug xov tooj txawb. Tsis muaj zem uas nyob rau lub forums ntau cov nqe lus nug yog nug nyob rau hauv lub ntiaj teb no Network rau yog vim li cas tus saib flickers. Rau ib tug me me muaj pes tsawg tus ntawm cov neeg, ib co tsis them sai sai mus rau nws, thaum lwm tus neeg tsis pom. Thiab tom qab ntau tshaj ib nrab lub ntiaj teb no tus pej xeem tau tuaj koom lub virtual zej zog pib tsim threads nrog ib tug lub npe "flickering saib!". Thaum xub thawj siab ib muag tej zaum nws yuav zoo li ntawd qhov teeb meem ntawm flicker tshaj plaws ntawm yav dhau los, zoo ua ke nrog loj saib raws li nyob rau hauv cathode txoj sab ci hlab (CRT), tab sis nws yog qhov yooj yim?

Yog hais tias tus saib yog flickering, nws tsim ib tug ntxiv tab kaum rau lub nruab nrog cev kev pom, tab sis thaum koj xav txog lub caij ntawm lub computer, qhov no qhov teeb meem yog qho tseem ceeb heev. Yuav kom to taub, thiab thaum kawg los teev lub "i", tej zaum, yog yuav pib nrog ib tug me ntsis keeb kwm.

Rau ib ntev lub sij hawm, tag nrho cov computer saib teem rau lub hauv paus ntawm ib tug CRT. Qhov no technology xwb yog tsis yog nws. Txawm tias nrog kev pab raws qib xws li tso saib ib tug hauj lwm zoo heev, muaj ntau yam cov neeg muaj feem ntau hais tias tus flickering saib. Lawv kiag li txoj cai. Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm lub CRT yog tias ntau yam ntws ntawm electrons tswj magnetic teb poob mus rau lub puab nto ntawm lub CRT coated nrog ib tug tshwj xeeb pes tsawg leeg. Nyob rau hauv qhov chaw ntawm uas nkag mus rau ntws pes tsawg leeg (phosphor) puv. Rays yog twv zoo li ib tug kab-by-line, tsiv los ntawm sab saum toj mus rau nram qab. Ces txhua yam yog rov qab.

Lub sij hawm "zaub zaus" qhia tias pes tsawg lub sij hawm ib ob rays tsim cov duab ntawm qhov screen. Vim lub persistence ntawm ib tug illusion ntawm ib tug holistic daim duab. Feem ntau cov neeg saib flicker ntawm ib zaus tsawg tshaj li 75 Hz, txawm hais tias nws tag nrho cov nyob rau hauv lub physiological yam ntxwv. Yog xav paub ntxiv txog CRT yuav ua hauj lwm rau tshwj xeeb qhov chaw thiab nyob rau hauv cov ntaub ntawv. Yog li, rau tshem tawm flicker CRT saib yuav ua tau tiav los ntawm kev xaiv ib tug graphics tsav tsheb, ib tug ntau dua zaus.

Tab sis tam sim no xav nyob rau hauv cov nqe lus nug ntawm yog vim li cas lub flickering LCD saib. Nyob rau hauv muaj ntau yam forums rau no qhov teeb meem zes loj sib cav tswv yim. Tab sis thaum lub sij hawm lub LCD (kua siv lead ua zaub) technology cam hais tias qhov teeb meem yog kiag li solved flicker, raws li cov ntsiab cai ntawm daim duab yog txawv heev. Nws muab tawm hais tias nyob rau hauv rooj plaub no tus producers ib tug me ntsis cunning, muab ib tug ib nrab-qhov tseeb. Thiab ntawm no yog tus tshaj plaws. Lub matrix nws tus kheej, nyob rau hauv uas lub hlwb yog xa tuaj nrog kua muaju tsis flicker, txhua txhua lub caij ntawm kev tsim ib zoo li qub duab.

Nrog hluav taws xob qij tes paub tag nrho (nco ntsoov lub hom nto moo "Montana"). Lub load rau hauv lub qhov muag thaum koj nrhiav ntawm cov xov tooj yog tib yam li nyob rau hauv txoj kev tshawb no ntawm phau ntawv rau ib daim ntawv ntawm daim ntawv (ntawm chav kawm, yog tias koj tsis coj mus rau hauv tus account qhov txawv nyob rau hauv loj). Nws yog tag nrho cov cai. Tab sis qhov teeb meem yog hais tias lub duab tsim los ntawm cov kua siv lead ua yuav pom xwb nyob rau hauv lub xub ntiag ntawm ib lub teeb qhov chaw pov tseg rau hauv lub rov qab sab. Tus saib yog xav ambient lub teeb los ntawm lub substrate, tab sis nyob rau hauv saib kev backlight. Tam sim no lawv muaj kev koom hloov kab ntawm LEDs. Feem ntau cov adjustable brightness LCD saib qauv no qhov chaw yog tiav los ntawm modulating lub hwj chim pulses, uas ua rau flicker. Ntawm cov hoob kawm, tus nqi yog tsis qis tshaj li 140 Hz (feem ntau tshaj 200), tab sis nws yeej nyob ntawd thiab muaj lub cev muaj cov tsis xis nyob. Tshuaj: xaiv tus qauv tsis muaj ib tug PWM los yog zaub brightness 100%.
