Masiku ano ndi chitukuko chofulumira chaukadaulo wamakono, ma module owonetsera ma LCD akhala gawo lofunikira m'miyoyo yathu.Kaya ndi ma TV ndi makompyuta kunyumba, kapena zikwangwani ndi maloboti m'malo ogulitsa, tonse titha kuwona zowonetsera za LCD LTPS.Komabe, pamene nthawi yogwiritsira ntchito ikuwonjezeka, ogwiritsa ntchito ayamba kumvetsera moyo wautumiki wa LCD LTP zowonetsera.Ndiye, moyo wautumiki wa chiwonetsero cha LCD ndi utali wotani?
Choyamba, tiyeni timvetsetse mfundo yogwira ntchito ya module yowonetsera ya LCD.LCD imayimira Liquid Crystal Display, yomwe imakwaniritsa zowonetsera poyang'anira dongosolo la mamolekyu amadzimadzi.Chiwonetsero cha LCD ltps chimapangidwa ndi mayunitsi angapo amadzimadzi amadzimadzi.Chigawo chilichonse chamadzimadzi chamadzimadzi chimatha kuwongolera ma pixel ochepa kuti apange chithunzi pazenera lonse.Mayunitsi amadzimadzi amadzimadziwa amayendetsedwa ndi ma transistors owonda kwambiri (TFTs), ndipo TFTs ndiye chinsinsi chowongolera gawo lililonse lamadzimadzi.
Kutengera mfundo zomwe zili pamwambazi, titha kusanthula zinthu zingapo zofunika pamoyo wautumiki wa chiwonetsero cha LCD LTP.Choyamba ndi moyo wa mamolekyu amadzimadzi a crystal.Mamolekyu amadzimadzi amadzimadzi amakalamba pakapita nthawi, zomwe zimapangitsa kuti mtundu wa chiwonetserocho ukhale wolakwika.Chachiwiri ndi moyo wa transistor wochepa thupi.TFT ndiye chinsinsi choyendetsera gawo lamadzimadzi, ndipo moyo wake umakhudza moyo wautumiki wa chinsalu chonse.Kuphatikiza apo, mawonetsedwe a LCD LTP ali ndi zigawo zina zofunika, monga magetsi, kuwala kwambuyo, ndi zina zotero, ndipo moyo wawo udzakhalanso ndi zotsatira pa moyo wautumiki wawonetsero.
Ponseponse, moyo wautumiki wa module yowonetsera LCD nthawi zambiri umawerengedwa mu maola.Nthawi zambiri, moyo wa chiwonetsero cha LCD ndi pakati pa 10,000 ndi 100,000 maola.Komabe, moyo wautumiki uwu siwokhazikika ndipo udzakhudzidwa ndi zinthu zambiri.Mwachitsanzo, khalidwe, malo ogwiritsira ntchito, njira yogwiritsira ntchito, ndi zina za module yowonetsera LCD zonse zidzakhudza moyo wautumiki.Choncho, ngakhale ndi mtundu womwewo ndi chitsanzo cha module yowonetsera LCD, moyo wake wautumiki ukhoza kukhala wosiyana.
Choyamba, tiyeni tiwone momwe mawonekedwe a LCD ltps amawonetsera pa moyo wake wautumiki.Mitundu ndi mitundu yosiyanasiyana ya zowonetsera za LCD zimakhala ndi mikhalidwe yosiyana chifukwa chogwiritsa ntchito zida ndi matekinoloje osiyanasiyana.Nthawi zambiri, zowonetsera zapamwamba za TFT zimagwiritsa ntchito mamolekyu apamwamba kwambiri amadzimadzi amadzimadzi ndi ma transistors a kanema owonda, omwe amatha kukulitsa moyo wautumiki ndikuwonetsetsa kugwira ntchito.Zowonetsa za LCD zotsika kwambiri zitha kukhala ndi moyo wamfupi wautumiki chifukwa cha kuchepa kwa zida ndi njira.Choncho, pogula tft display screen, tiyenera kuyesetsa kusankha mtundu odziwika ndi zinthu zapamwamba.
Kachiwiri, malo ogwiritsira ntchito ndi chimodzi mwazinthu zofunika zomwe zimakhudza moyo wautumiki wa gawo lowonetsera la LCD.Chiwonetsero cha LCD ltps chili ndi zofunikira pazachilengedwe monga kutentha, chinyezi, fumbi, ndi zina. Kutentha kwambiri kapena kutsika kwambiri kumakhudza momwe ma molekyulu amadzimadzi amadzimadzi amagwirira ntchito, potero kufupikitsa moyo wautumiki wa skrini yowonetsera.Chinyezi chochuluka chidzapangitsa kuti transistor yowondayo ikhale yofupikitsa, motero zimakhudza moyo wautumiki wa chiwonetsero chonse.Kuonjezera apo, zonyansa monga fumbi zidzayikidwanso pamwamba pa chinsalu chowonetserako, ndipo zidzadziunjikira mowonjezereka pakapita nthawi, kuchepetsa kuwonekera kwa chinsalu chowonetsera.Chifukwa chake, tikamagwiritsa ntchito chophimba cha tft, tiyenera kuyesetsa kuchiyika pamalo owuma komanso aukhondo.
Kuphatikiza apo, momwe timagwiritsira ntchito zikhudzanso moyo wautumiki wa chiwonetsero cha LCD.Mwachitsanzo, kuyatsa chiwonetserochi kwa nthawi yayitali kumapangitsa kuti mamolekyu am'mbuyo ndi ma crystal amadzimadzi azigwira ntchito kwa nthawi yayitali, ndikuwonjezera chiopsezo cha ukalamba.Kuigwiritsa ntchito pakuwala kwambiri kwa nthawi yayitali kumathandiziranso kuchepetsedwa kwa kuwala kowonetsera.Chifukwa chake, tikamagwiritsa ntchito chophimba cha tft, tiyenera kuyesa kuwongolera nthawi yotsegulira ndi kuwala kuti tiwonjezere moyo wake wautumiki.
Kuphatikiza apo, tifunikanso kulabadira zina zogwiritsiridwa ntchito kuti tiwonetsetse moyo wautumiki wanthawi yayitali wa chiwonetsero cha LCD LTP.Mwachitsanzo, fumbi ndi madontho pamalo owonetsera ziyenera kutsukidwa nthawi zonse, koma zida zapadera zoyeretsera ziyenera kugwiritsidwa ntchito kupewa kuwononga malo owonetsera.Panthawi imodzimodziyo, samalani ponyamula ndi kusuntha zowonetsera kuti mupewe kugunda ndi kufinya.Kuphatikiza apo, zosintha zamapulogalamu nthawi zonse ndi kukonza ndi kukonza zitha kukulitsa moyo wautumiki wa chiwonetsero cha LCD.
Mwachidule, moyo wautumiki wa gawo lowonetsera LCD umatsimikiziridwa ndi zinthu zingapo.Ngakhale kuti nthawi zambiri, nthawi ya moyo wa LCD LTP zowonetsera ndi pakati pa 10,000 ndi 100,000 maola, koma moyo weniweniwo ukhoza kukhudzidwa ndi zinthu monga khalidwe, malo ogwiritsira ntchito, ndi njira zogwiritsira ntchito.Chifukwa chake, tikamagula ndikugwiritsa ntchito chophimba cha tft, tiyenera kusankha zinthu zapamwamba kwambiri ndikuyang'ana malo ogwiritsira ntchito komanso momwe amagwiritsidwira ntchito kuti awonjezere moyo wake wantchito.Panthawi imodzimodziyo, zosintha panthawi yake ndi kukonza zingathenso kusunga ntchito ndi moyo wautali wawonetsero.Ndi njira iyi yokha yomwe tingasangalale nayo bwino komanso zosangalatsa zomwe zimabweretsedwa ndi chiwonetsero cha LCD.
