I. kuumbwa nheyo yeLCD
The liquid crystal
Chidzitiro chinotaridzika senge chidzitiro chimwe chete, kutaura zvazviri, chinonyanya kuumbwa nezvidimbu zvina zvakakura (sefa, polarizer, girazi, inotonhora cathode fluorescent rambi), pano kuti ndikupe tsananguro pfupi.
Sefa: chikonzero nei TFT LCD pani inogona kuburitsa shanduko yeruvara inonyanya kubva kune ruvara sefa.Iyo inonzi liquid crystal panel inogona kuita kuti mvura yekristaro mamorekuru amire mumutsara kuburikidza nemagetsi shanduko yekutyaira IC, kuitira kuratidza mufananidzo.Iyo pikicha pachayo yakasviba uye chena, uye inogona kuchinjwa kuva ruvara patani kuburikidza nesefa.
Polarizing plate: polarizing plate inogona kushandura mwenje wechisikigo kuita mutsara wepolarizing zvinhu, kuita kwayo kuparadzanisa mwenje wemutsara unouya une polarizing zvikamu, chimwe chikamu ndechekuita kuti ipfuure, chimwe chikamu kunyura, kuratidza, kuparadzira uye zvimwe zvinokonzeresa kuti iite. zvakavanzika, kuderedza chizvarwa chemashoko akajeka / akaipa.
Cold cathode fluorescent rambi: inoratidzirwa nehuwandu hudiki, kupenya kwepamusoro uye hupenyu hurefu. Yakagadzirwa negirazi yakanyatsogadzirwa uye yakagadziriswa, mwenje inotonhora ye cathode fluorescent inogona kushandiswa kakawanda mushure mekukurumidza kuvhenekera uye inogona kumira kusvika ku30,000 kuchinja maitiro.Nekuda kwekuti inotonhora cathode fluorescent rambi INOSHANDISA matatu-ruvara phosphor hupfu, saka kupenya kwayo kunowedzera, kuderera kwechiedza kuderera, tembiricha yeruvara ichiita yakanaka, nokudaro inoburitsa huwandu hwekupisa hwakaderera zvakanyanya, zvinodzivirira zvinodzivirira yedu yemvura kristaro kuratidza hupenyu.
Zvinokonzera uye kudzivirira kweakajeka / akashata makwapa emvura crystal
1. Zvikonzero zvemugadziri:
Iyo inopenya / yakaipa nzvimbo inozivikanwa zvakare seyakajeka nzvimbo yeLCD, inova rudzi rwekukuvara kwemuviri kweLCD.Inonyanya kukonzerwa nekumanikidzwa kwekunze kwesimba kana kuti deformation shoma yemukati yekuratidzira ndiro yenzvimbo inopenya.
Pixel imwe neimwe paLCD skrini ine mavara matatu ekutanga, dzvuku, girini nebhuruu, izvo zvinosangana kuti zvibudise mavara akasiyana-siyana.Tora 15-inch LCD semuenzaniso, nzvimbo yayo yeLCD skrini i304.1mm*228.1mm, resolution i1024* 768, uye imwe neimwe LCD pixel inoumbwa neRGB primary color unit.Liquid crystal pixels i "liquid crystal boxes" inoumbwa nekudira mvura crystal muforoma yakagadzika.Nhamba yeakadaro "mvura yekristaro mabhokisi" pane 15-inch LCD kuratidzwa ndeye 1024 * 768 * 3 = 2.35 mamiriyoni! Chii chinonzi LCD bhokisi? = 0.099mm!Nemamwe mazwi, 2.35 miriyoni "Liquid crystal boxes" ine nzvimbo ye 0.297mm * 0.099mm chete yakarongwa zvakanyanya pasi penzvimbo ye304.1mm * 228.1mm, uye dhiraivha inotyaira iyo liquid crystal box inosanganiswa. seri kweiyo liquid crystal box.Zviri pachena, zvinodiwa zvekugadzirwa kwemutsara wekugadzira zvakanyanya, pane tekinoroji iripo uye hunyanzvi, zvakare haigone kuvimbisa kuti batch imwe neimwe inoburitsa LCD skrini haina kupenya / yakaipa mapoinzi, vagadziri vanowanzo dzivirira yakajeka / yakaipa pfungwa segment LCD panel, hapana mapoinzi akajeka/akaipa kana mashoma anopenya makwapa/akaipa LCD pani yevagadziri vane simba, uye mwenje/yakaipa mapoinzi akawanda LCD sikirini kazhinji inoshomeka vagadziri vadiki mukugadzira yakachipa LCD.
Nehunyanzvi, inopenya/yakashata nzvimbo ipikisi isingagadzirike pane LCD panel inogadzirwa panguva yekugadzira.Iyo LCD panel inoumbwa neyakagadziriswa liquid crystal pixels, imwe neimwe ine matatu transistors anoenderana nered, girinhi uye bhuruu sefa. 0.099mm liquid crystal pixel
Transistor yakashata kana kuti short circuit inoita kuti pixel iyi ive inopenya/yakaipa poindi.Pamusoro pezvo, pixel yega yega yeLCD inosanganiswa kuseri kwechubhu yemutyairi yakaparadzana kuti ityaire. haigone kuchinja ruvara uye ichava nzvimbo yakagadzika yeruvara, iyo inozoonekwa zvakajeka mune mamwe mavara ekumashure.Iyi ndiyo nzvimbo yakajeka / yakaipa yeLCD.Bright / bad spot imhando yekukuvara kwemuviri kusingagoni kudziviswa 100% mukugadzirwa uye kushandiswa kweLCD skrini.Muzviitiko zvakawanda, inogadzirwa mukugadzirwa kwekrini.As long as imwe kana akawanda emavara ekutanga anoumba pixel imwe chete akanganiswa, mavara akajeka / akaipa anogadzirwa, uye kugadzirwa uye kushandiswa kungangokonzera kukanganisa.
Zvinoenderana negungano renyika dzakawanda, mvura yekristaro inoratidzira ine 3 pazasi inopenya / yakaipa poindi iri mukati meiyo inotenderwa, zvisinei mutengi haafanire kunge achida kutenga iyo inopenya / yakaipa poindi kana uchitenga mvura yekristaro, saka mugadziri wekristaro yemvura. iyo ine inopenya / yakaipa poindi inowanzo tengesa yakaoma kwazvo.Vagadziri vepaneru vanobata sei nematatu kana anopfuura akajeka / akashata makwapa nekuda kwekugadzirwa kwemaitiro?Kuti vawane purofiti, vamwe vanogadzira havaparadzi idzi LCD skrini, uye kazhinji, ivo achashandisa midziyo yehunyanzvi kurapa iyo yakaipa / yakaipa makwapa, kuitira kuti iwane mhedzisiro yepasina yakaipa / yakaipa mavara pamusoro pemeso.Vashoma vanogadzira havatomboiti kugadzirisa, vanoisa zvakananga mapaneru aya mumutsara wekugadzira. yekugadzira, kuitira kuti uwane chinangwa chekudzikisa mari.Iri rudzi rwechigadzirwa rine mukana mumutengo, asi richabudisa mavara akajeka / akaipa nokukurumidza mushure mekushandisa.Parizvino pamusika zvakawanda zvakachipa zvekristaro zvemvura zvakachipa zvakadaro.yakagadziridzwa, saka haudi kutenga kristaro yemvura yakachipa, kutenga mamwe mazita asingazivikanwe. Ndafara kutenga yakaderera - isingadhuri - inopenya kuratidza. Nekuti mushure mechinguva, zvinhu zvausingadi kuona zvinogona kupedzisira zvaitika.
2. Zvikonzero zvekushandisa
Mamwe maLCD anopenya / akashata mapoinzi anogona kukonzerwa nekushandiswa kweiyo maitiro, ingokuudza nezve yakajairika kushandiswa kwemamwe matanho ekuchenjerera:
(1) usaise akawanda masisitimu panguva imwe chete; Kuiswa kweakawanda masisitimu mukuchinja kunokonzeresa imwe nhanho yekukuvadza kuLCD.
(2) chengetedza magetsi uye simba zvakajairika;
(3) usabate bhatani reLCD chero nguva.
Zvose izvi zvitatu zvinokanganisa zvakananga kana zvisina kunanga zvinokanganisa kushandiswa kwemaitiro e "liquid crystal box" mamorekuru, izvo zvinogona kutungamirira kukugadzirwa kwemavara akajeka / akaipa.Kutaura zvazviri, nzvimbo dzakajeka / dzakaipa dzevatengi mukushandiswa kwekushandisa zvinogona kunzwisiswa. kuburikidza nekuongorora mainjiniya.Kunyange nzvimbo dzakajeka / dzakaipa dzevatengi dzinogona kunzwisiswa kana vagadziri vasingakuvadzi vatengi vasina hana.
Chiyero chenyika ndeche 335, zvichireva kuti mavara matatu akajeka, kana mavara matatu akasviba, anokodzera seakajairwa.
