Aha flickers aroturuki

Ki te i te ata o te rorohiko te papamahi i te kāinga autaki tohu o te haumarutanga me te makehe āheinga pāngarau o tona rangatira, i roto i te tekau tau e rua whakamutunga, kua ripeneta ke te āhuatanga. Kua riro rorohiko me rorohiko kuku rite maheni o te ora hou, rite he mīhini horoi aunoa i te waea pūkoro ranei. No miharo e i runga i te Ngā Huinga atu pinepine ui te pātai kei roto i te Global Whatunga i aha flickers te aroturuki. Hoki te maha iti o ngā kaiwhakamahi, kore etahi e whakarongo ki reira, i ētahi atu e kore e kite. A i muri i neke atu i te hawhe taupori o te ao kua piri timata te hapori mariko ki te hanga i ngā miro ki te ingoa nui "keto aroturuki!". I mawhiti tuatahi mea he kia e ngaro tahi te raruraru o te mea kōpura o te mua, me te aroturuki i mōmona e hāngai ana i runga i ngongo hihi pito tōraro (CRT), engari te mea ohie?

Ki te te keto te aroturuki, hanga reira he pikaunga atu i runga i nga whekau o aroaro, engari ka whakaaro koutou i te roanga o te rorohiko, he tino nui tenei take. Hei matau reira, a pae hopea ki ia amuihia i te "i", pea, ko te ki te timata ki te hītori iti.

Hoki te wa roa, whakatakotoria te aroturuki i rorohiko katoa ake i runga i te pūtake o te CRT. Tenei hangarau noa kihai i ahurei. Ahakoa ki ngā mahi whakaatu taua whakaaro he mahi pai, kua maha kī maha kaiwhakamahi e te aroturuki e tineia e. Ko tino tika ratou. Ko te parau tumu whakahaere o te CRT ko e hinga awa maha o irahiko te mana mara autō ki runga te mata i roto o te CRT pani ki te hanganga motuhake. I roto i te wahi o te tomokanga rere hanganga (phosphor) tahuri. E unu hihi rite te aho-i-aho, neke i runga ki raro. Na ka korerotia nga mea katoa te.

Ko te wā "auau whakaatu" tohu e hia nga wa ia hihi tuarua hanga te whakapakoko i runga i te mata. Nā ki te vilitakí o te tokonga o te pikitia katoa. kite te nuinga o te iwi kōpura i te auau iti iho i te 75 Hz, ahakoa reira katoa tei runga i te āhuatanga whaiaroaro. Mō ētahi atu pārongo e pā ana ki CRT taea te mahi i runga i ngā pae motuhake, me te i roto i ngā tānga. Ko te kupu, ki te whakakore i taea kōpura CRT aroturuki kia tutuki mā te tīpako i te atekōkiri whakairoiro, he auau teitei.

Tena ko tenei ake hiahia i roto i te pātai o te aha te aroturuki e tineia e LCD. I roto i te maha Huinga i runga i tenei take whakakā tautohetohe nui. Otiia i te wa tautohe te LCD (whakaatu kōataata wai) hangarau e te tino i te raruraru faatiti'aifarohia te kōpura, i te mea he tino rerekē te parau tumu o te whakapakoko. tahuri te reira i roto i taua i roto i tenei take i te kaihanga i te iti te tohunga, whakahere he-pono hawhe. Na konei te te mea. Te kopu ano, i roto i nei E kopakia ana nga pūtau tioata wai e kore e kemo, kau katoa o te hanga i te whakapakoko pateko.

Ki te wristwatch hiko mohio katoa (mahara te waitohu rongonui "Montana"). Ko te kawenga i runga i te kanohi ina titiro koe i nga tau, ko te taua rite i roto i te ako o te kuputuhi i runga i te whārangi o te pepa (o te akoranga, ki te kahore e tangohia e koe ki te pūkete te rerekētanga i roto i te rahi). He mea tika katoa. Ko te raruraru ko e te whakapakoko i hanga e te karaihe wai riro kitea anake i roto i te aroaro o te puna te marama nga tikanga i runga i te taha ki hoki. Kei te whakaata te tiaki marama ambient i te tïpako, engari i roto i te aroturuki ngātahi backlight. Na e kaha whakakapi ratou aho o LED. Te nuinga wherikotanga te whakarite tauira LCD aroturuki enei puna tutuki e modulating te ngātere mana, hua i roto i te kōpura. O te akoranga, ko te kore i raro ake i te 140 Hz (nuinga i runga i 200) te auau, engari he reira i reira, ka ua tinana o te hūhi e rua. Rongoā: whiriwhiri i te tauira, kahore PWM whakaatu ranei i te wherikotanga ki te 100%.
