Sei Monitor flickers

Kana ari mambakwedza kadambari munhu pakombiyuta pamba zvisina kunanga anoratidza kuchengetedzwa uye aakatipa mano kwemasvomhu kwayo muridzi, mumakore maviri emakore, zvinhu anenge zvikuru achinja. Computers uye Laptops vava sezvo yaizivikanwa zvaiva nechokuita upenyu ano, kufanana otomatiki wokuwachisa kana serura. Hazvishamisi kuti uri forum kakawanda mubvunzo akakumbirwa muna Global Network kuti nei Monitor flickers. Nokuti vashoma vanoshandisa, vamwe regai kuriteerera, nepo vamwe regai cherechedzai. Uye pashure kupfuura hafu yevagari vepasi akabatana rakapotsa vomunharaunda akatanga kuumba shinda ane zita guru "flickering tarisisa!". Pakutanga zvingaita sokuti dambudziko kudzima chinhu chekare, akanyangarika pamwe kura monitors kwakavakirwa cathode ranzi sepombi (CRT), asi zviri nyore?

Kana tarisisa iri flickering, izvozvo anosika wokuwedzera mutoro pamusoro nhengo pameso, asi kana iwe funga ya pakombiyuta, nyaya iyi inokosha zvikuru. Kurinzwisisa, uye pakupedzisira kuti tira kuti "Ini", zvichida, ndiko kutanga zvishoma nhoroondo.

Kwenguva refu, zvose kombiyuta monitors akamisa pahwaro imwe CRT. Michina iyi chete handivo voga. Kunyange zvazvo mabasa akadaro namano kuratidza rakaisvonaka basa, vanoshandisa vakawanda kazhinji akataura kuti flickering Monitor. Vaiva zvachose zvakanaka. The uchishandisa nheyo CRT ndechokuti vakawanda Hova maerekitironi dzinodzorwa rinobva minda awire mukati pose CRT zvemapuranga chaiwo sezvamunoita. In nzvimbo pangapindwapo runoyerera sezvamunoita (phosphor) kwaanoda. Mwaranzi vanokwezvwa akafanana mutsetse-ne-mutsetse, kutamira kubva kumusoro kusvikira pasi. Zvadaro zvose inodzokororwa.

Shoko rokuti "Kuratidzwa maitikiro" rinoratidza kangani paminiti wechipiri mwaranzi kusika chifananidzo chidzitiro. Nokuda kutsungirira ane fungidziro ane RUBATSIRO RUNOTARISA mufananidzo. Vanhu Vazhinji ona kudzima ari kakawanda asingasviki 75 Hz, kunyange zvazvo zvose kunobva vasiri unhu. Kuti uwane mamwe mashoko pamusoro CRT anogona kushanda kushandiswa nzvimbo uye mabhuku. Saka, kubvisa kudzima CRT tarisisa anogona kuitwa Yasarudza Graphics mutyairi, wakakwirira maitikiro.

Asi ikozvino kufarira mubvunzo kuti nei flickering LCD Monitor. In forum zhinji panyaya iyi vesa zvakakomba gakava. Asi panguva LCD (mvura sekristaro vanoratidza) ano vanoti dambudziko iri rwakapedza kudzima zvachose, sezvo nheyo mufananidzo zvakasiyana. Zvakazozivikanwa kuti iyi nyaya yacho vaburitsi zvishoma wakachenjera, kupa nehafu-chokwadi. Uye pano chinhu. Chizvaro pacharo, umo masero vari akanyudzwa emura crystals regai kudzima, nguva yose pakusika chifananidzo kunofambira mberi.

With zvemagetsi wristwatch munoziva zvose (rangarira akakurumbira muchiso "Montana"). The mutoro uri ziso kana uchitarisa nhamba kwakafanana kudzidza rugwaro papepa (Chokwadi, kana musingadi kufungawo musiyano iri kukura). Zvakanaka. Asi dambudziko riri kuti mufananidzo inoumbwa nemvura sekristaro anova kuoneka chete pamberi chiedza tsime dzinongoda ari seri. Vakarinda kufungisisa ambient chiedza kubva substrate, asi mune monitors revatema backlight. Zvino vari kushingaira kutsiva dzinza LEDs. Most chinjika Kupenya LCD tarisisa mienzaniso Zvinyorwa izvi zvinoitwa modulating simba pulses, zvichiguma kudzima. Chokwadi, nhamba haina kudzika pane 140 Hz (yemanyorero 200), asi pane uye akanzwa zvitunha zvose zvakanaka. Solution: kusarudza muenzaniso pasina PWM kana kuratidza kubwinya kusvika 100%.
