Ruwan crystal
Allon yana kama da allo ɗaya kawai, a zahiri, an haɗa shi da manyan guda huɗu (tace, polarizer, gilashi, fitilar cathode mai sanyi), anan don ba ku taƙaitaccen bayani.
Tace: dalilin da yasa TFT LCD panel zai iya samar da canjin launi shine yafi daga tace launi.Abin da ake kira ruwa crystal panel zai iya sa kwayoyin kristal ruwa su tsaya a layi ta hanyar canjin wutar lantarki na tuki IC, don nuna hoton.Hoton da kansa baƙar fata ne, kuma ana iya canza shi zuwa tsarin launi ta hanyar tacewa.
Polarizing farantin: polarizing farantin zai iya canza halitta haske zuwa mikakke polarizing abubuwa, wanda aikinsa shi ne ya raba layin da ke shigowa tare da abubuwan polarizing, wani sashi shine ya wuce, ɗayan ɓangaren shine sha, tunani, watsawa da sauran tasirin yin shi. boye, rage tsarar haske / mummunan maki.
Cold cathode fluorescent fitila: yana da ƙananan ƙararrawa, babban haske da tsawon rai.Made na musamman da aka tsara da kuma sarrafa gilashin, ana iya amfani da fitilun cathode mai sanyi akai-akai bayan saurin haske kuma yana iya tsayayya da ayyukan sauyawa na 30,000. Domin sanyi cathode fluorescent. fitila tana amfani da foda mai launi uku, don haka ƙarfinsa yana ƙaruwa, raguwar haske yana raguwa, aikin zafin launi yana da kyau, don haka yana haifar da ƙarancin zafi sosai, yana ba da kariya ga kristal ɗin mu na ruwa sosai.
Dalilai da rigakafin guraben haske/mara kyau na kristal ruwa
1. Dalilan masana'anta:
Ana kuma san wurin mai haske/mara kyau a matsayin wuri mai haske na LCD, wanda shine nau'in lalacewar jiki na LCD.Ana haifar da shi ne ta hanyar matsawa ƙarfin waje ko ɗan nakasar farantin tunani na ciki na tabo mai haske.
Kowane pixel akan allon LCD yana da launuka na farko guda uku, ja, kore da shuɗi, waɗanda ke haɗuwa don samar da launuka iri-iri. Ɗauki LCD mai inci 15 a matsayin misali, yankin allo na LCD 304.1mm * 228.1mm, ƙuduri shine 1024* 768, kuma kowane LCD pixel yana kunshe da naúrar launi na farko na RGB. Liquid crystal pixels sune "akwatunan crystal ruwa" da aka kafa ta hanyar zuba kristal ruwa a cikin tsayayyen tsari.Yawan irin waɗannan "akwatunan crystal ruwa" akan nuni na 15-inch LCD shine 1024 * 768 * 3 = 2.35 miliyan! Menene girman akwatin LCD? Za mu iya ƙididdigewa cikin sauƙi: tsawo = 0.297mm, nisa = 0.297/3 = 0.099mm. a baya da ruwa crystal akwatin.A bayyane yake, samar da tsari bukatun na samar line ne sosai high, a halin yanzu fasaha da kuma sana'a, kuma ba zai iya tabbatar da cewa kowane tsari samar LCD allon ba haske / bad maki, masana'antun kullum kauce wa haske / bad maki zuwa. bangare LCD panel, babu wani haske / bad maki ko sosai 'yan haske spots / bad LCD panel na high wadata iko masana'antun, da kuma haske / bad maki more LCD allo ne kullum low wadata kananan masana'antun a samar da cheap LCD.
Ta hanyar fasaha, wuri mai haske / mara kyau shine pixel da ba za a iya gyarawa ba akan wani panel na LCD wanda aka samar a yayin aikin masana'antu. The LCD panel yana kunshe da ƙayyadaddun pixels na ruwa mai tsabta, kowannensu yana da transistor guda uku daidai da ja, kore da blue filter bayan 0.099mm ruwa crystal pixel
Kuskuren transistor ko gajeriyar kewayawa yana sa wannan pixel ya zama mai haske/mara kyau. Bugu da ƙari, kowane pixel na LCD kuma an haɗa shi a bayan bututun direba daban don fitar da shi. Idan ɗaya ko fiye na ja, kore da shuɗi na farko sun kasa, pixel ba zai iya canza launi a al'ada ba kuma zai zama tsayayyen wurin launi, wanda za a iya gani a fili a wasu launuka na bango.Wannan shine madaidaicin haske / mara kyau na LCD.Bright / mummunan tabo shine nau'in lalacewar jiki wanda ba za a iya kauce masa 100% a cikin samarwa da amfani da allon LCD ba.A mafi yawan lokuta, ana samar da shi a cikin masana'anta na allon. Idan dai ɗaya ko fiye na launuka na farko waɗanda ke yin pixel guda ɗaya sun lalace, ana haifar da wurare masu haske / mara kyau, kuma samarwa da amfani na iya haifar da lalacewa.
Dangane da yarjejeniyar kasa da kasa, nunin kristal na ruwa yana da 3 a ƙasa mai haske / mummunan ma'ana yana cikin kewayon da aka ba da izini, duk da haka mabukaci ba zai yuwu ya sayi na'urar saka idanu wanda ke da ma'ana mai haske / mara kyau lokacin siyan kristal na ruwa, don haka masana'antar kristal ruwa. Ta yaya masana'antun panel ke magance uku ko fiye mai haske / mara kyau saboda tsarin samarwa? Don samun riba, wasu masana'antun ba za su lalata waɗannan allon LCD ba, kuma a mafi yawan lokuta, suna za su yi amfani da ƙwararrun kayan aiki don magance mummunan / mummunan aibobi, don cimma sakamakon da ba su da kyau / mara kyau a saman ido zuwa ido tsirara. Wasu masana'antun ba ma yin aikin sarrafawa, kai tsaye sanya waɗannan bangarori a cikin layin samarwa. don samarwa, don cimma manufar rage farashin.Wannan nau'in samfurin yana da fa'ida a cikin farashi, amma zai samar da haske / mara kyau ba da daɗewa ba bayan amfani.sarrafa fitar, don haka ba ka so ka saya ruwa crystal nuni cheap, saya wasu unknown brands.Glad saya low – kudin non – haske nuni.Domin bayan wani lokaci, abubuwan da ba ka so ka gani na iya ƙarshe faru.
2. Dalilan amfani
Wasu LCD masu haske/mara kyau na iya haifar da amfani da tsarin, kawai gaya muku game da yadda aka saba amfani da wasu matakan tsaro:
(1) kar a shigar da tsarin da yawa a lokaci guda; Shigar da tsarin da yawa a cikin tsarin sauyawa zai haifar da wani nau'i na lalacewa ga LCD.
(2) kiyaye ƙarfin lantarki da ƙarfin al'ada;
(3) kar a taɓa maɓallin LCD a kowane lokaci.
Duk waɗannan abubuwa guda uku kai tsaye ko a kaikaice suna shafar aikin al'ada na kwayoyin "akwatin crystal", wanda zai iya haifar da samar da abubuwa masu haske / mara kyau. A gaskiya ma, za a iya fahimtar ma'auni mai haske / mara kyau na masu amfani a cikin tsarin amfani. ta hanyar duba injiniyoyi.Ko da haske / mummunan tabo na masu amfani za a iya fahimta idan masana'antun ba su cutar da masu amfani ba tare da lamiri ba.
Ma'auni na ƙasa shine 335, ma'ana tabo masu haske uku, ko tabo masu duhu uku, sun cancanta kamar al'ada.
