La yaab ma laha in on forums ah oo intaa ka badan su'aasha la weydiiyey in Network Caalamiga ah ee ku saabsan sababta kormeeraha damayaa. Waayo, tiro yar oo ah dadka isticmaala, qaar ka mid ah ma fiiro gaar ah u tahay in la, halka qaar kalena ma dareemaan. Oo ka dib markii in ka badan nus dadka dunida ayaa ku soo biiray bulshada dalwaddii bilaabay si ay u sameeyaan threads la magac weyn "eller monitor!".

Mabda'a hawlgalka ee CRT waa in durdurrada badan ee electrons gacanta beeraha magnetic dhici gal dusha hoose oo CRT ee dahaarka leh kula Halabuurka gaar ah. In meel of galo socodka Halabuurka (phosphor) jirsado. Rays group yihiin sida line-by-line a, dhaqaaqin top si hoose. Markaas wax kasta oo lagu celceliyo.

Erayga "noqnoqoshada bandhigay" waxay muujinaysaa sida ay marar badan halkii rays labaad abuuro image ee shaashadda. Sababo la joogtada ah ee ka khayaal ah sawir guud. Dadka intooda badan arki flicker at inta jeer ka yar 75 Hz, inkasta oo oo dhan waxay ku xiran tahay sifooyinka nafsaaniga ah. Wixii macluumaad dheeraad ah oo ku saabsan CRT shaqayn karin goobaha khaaska ah iyo in publications. Sidaas darteed, si loo baabi'iyo flicker monitor CRT waxaa lagu gaari karaa by xulashada darawalka muuqaallo kale ah, inta jeer sare.

Laakiinse haatan xiiso su'aasha ah sababta monitor LCD eller ah. In shirar badan oo ku saabsan arrintan u guban dood dhab ah. Laakiin waqti LCD (bandhigay dareere crystal) technology ee ku doodaya in dhibaatada la xalin si buuxda flicker ah, sida mabda'a of image waa arrin oo kala duwan. Waxaa soo baxay in ay dhacdo in this saarayaasha yar lagu daabacay, ee bixiya nus-runta. Oo halkan waxa. Matrix laftiisa, kaas oo unugyada waxaa ku lifaaqan kiristaalo dareere ma flicker, daqiiqad kasta oo abuuraya image ah ma guurto ah.

Iyada oo wristwatch electronic ogahay oo dhan (xusuuso brand caanka ah "Montana"). load The on isha marka aad eegto tiro waa la mid ah sida daraasadda of text on xaashi of warqad (of course, haddii aadan tixgeliyaan farqiga u size).

Hadda waxay si firfircoon bedelay line of Kokes. Inta badan dhalaalka hagaajin lagu daydo monitor LCD ilahaasi waxaa lagu gaarayaa by modulating karsado xoogga, taasoo keentay in flicker. Dabcan, heerka aan ka yarayn 140 Hz (caadi ahaan ka badan 200), laakiin waxaa jiro iyo dareemay meydadka labada raaxo. Solution: dooran model ah oo aan PWM ama bandhigay dhalaalka ah in 100%.
