1, LCD

LCD gajere ne don Nunin Liquid Crystal a Turanci.

Akwai galibi TFT, UFB, TFD, STN da sauran nau'ikan.Tsarinsa ya haɗa da ƙwallon filastik, ƙwallon gilashi, manne firam, gilashin gilashin, babban polarizer, Layer na shugabanci, crystal ruwa, ƙirar ITO mai gudanarwa, ma'anar gudanarwa, IPO electrode da ƙananan polarizer.

Ɗaukar allon talla na LCD a matsayin misali, yana ɗaukar mafi sanannun TFT-LCD, wanda shine nunin faifan fim na bakin ciki.Tsarinsa na asali shine sanya akwatin kristal ruwa a cikin nau'ikan gilashi guda biyu masu kama da juna, saita transistor fim na bakin ciki (wato TFT) akan ƙaramin gilashin ƙasa, saita tace launi akan gilashin ƙaramin gilashi na sama, ana sarrafa yanayin juyawa na ƙwayoyin kristal na ruwa ta siginar. kuma ƙarfin lantarki yana canzawa akan transistor na fim na bakin ciki, don cimma manufar nuni ta hanyar sarrafa ko hasken polarized na kowane pixel yana fitowa ko a'a.

Ka'idar nunin kristal ruwa shine kristal ruwa zai gabatar da halaye daban-daban na haske a ƙarƙashin aikin ƙarfin lantarki daban-daban.Allon nunin kristal mai ruwa ya ƙunshi tsararrun ruwa kristal da yawa.A cikin allon nunin nunin faifan kristal mai monochrome, crystal ruwa shine pixel (ƙananan naúrar da za a iya nunawa akan allon kwamfuta), a cikin allon nunin ruwan kristal mai launi, kowane pixel ya ƙunshi lu'ulu'u na ruwa ja, kore da shuɗi.A lokaci guda, ana iya la'akari da cewa akwai rajista na 8-bit a bayan kowane crystal na ruwa, kuma ƙimar rajistar ta ƙayyade haske na kowane ɗayan raka'a crystal ruwa uku, duk da haka, ƙimar rajista ba ta kai tsaye ba. fitar da haske na raka'a crystal ruwa guda uku, amma ana samun dama ta hanyar “palette.Ba gaskiya ba ne don samar da kowane pixel tare da rijistar jiki.A haƙiƙa, layi ɗaya kawai na rajista ke sanye.Ana haɗa waɗannan rijistar zuwa kowane layi na pixels bi da bi kuma an ɗora su cikin abubuwan da ke cikin wannan layin, suna fitar da duk layin pixel don nuna cikakken hoto.

2, LED SCREEN

LED gajere ne don Haske Emitting Diode.Wani nau'i ne na diode semiconductor, wanda zai iya canza makamashin lantarki zuwa makamashin haske.

Lokacin da aka haɗa electrons da ramuka, hasken da ake iya gani yana iya haskakawa, don haka ana iya amfani da shi don yin diodes masu fitar da haske.Kamar diode na gama-gari, diodes masu fitar da haske sun ƙunshi mahaɗar pn kuma suna da ɗawainiya ta unidirectional.

Ka'idarsa lokacin da aka ƙara ingantaccen ƙarfin lantarki zuwa diode mai haske, ramukan da aka allura zuwa yankin N daga yankin P da kuma allurar electrons a cikin yankin P daga yankin N, a cikin 'yan microns kusa da mahadar PN, an haɗa shi. tare da electrons a cikin yankin N da ramuka a cikin yankin P don samar da hayakin hayaki na kwatsam.

Jihohin makamashi na electrons da ramuka a cikin kayan semiconductor daban-daban sun bambanta.Lokacin da electrons da ramuka suka haɗu, adadin kuzarin da aka fitar ya bambanta.Da yawan kuzarin da aka fitar, shine guntun tsawon hasken da ke fitowa.Yawancin amfani da diodes masu fitar da haske ja, koren haske ko rawaya.

LED ana kiransa Hasken Haske na ƙarni na huɗu, wanda ke da halaye na ceton makamashi, kariyar muhalli, aminci, rayuwar sabis mai tsayi, ƙarancin wutar lantarki, ƙarancin zafi, babban haske, mai hana ruwa, ƙarami, mai ba da ƙarfi, sauƙin dimming, hasken haske mai haske, kulawa mai sauƙi. , da dai sauransu, ana iya amfani da shi sosai a fannoni daban-daban kamar nuni,LED nuni, ado, backlight, general lighting, da dai sauransu.

Alal misali, LED nuni allo, Talla LED Screen, Traffic siginar fitila, mota fitilar, LCD backlight, iyali lighting da sauran lighting kafofin.

3, OLED

OLED gajere ne don Organic Light-Emitting Diode.Har ila yau, an san shi da nunin laser lantarki na lantarki, hasken lantarki mai fitar da semiconductor.

Wani farfesa dan kasar Amurka Deng Qingyun ne ya gano wannan diode a dakin gwaje-gwaje a shekarar 1979.

OLED ya ƙunshi naúrar nunin OLED na waje da kayan fitar da haske da aka makale a ciki, gami da cathode, Layer emission, Layer conductive, anode da tushe.Kowace rukunin nunin OLED na iya sarrafawa don samar da hasken launuka daban-daban guda uku.

Fasahar nunin OLED tana da siffa ta hasken kai, ta yin amfani da murfin kayan halitta na bakin ciki sosai da gilashin gilashi.Lokacin da zazzagewar wutar lantarki, waɗannan kayan halitta za su fitar da haske, kuma kusurwar gani na allon nuni na OLED yana da girma, kuma yana iya adana amfani da wutar lantarki.Tun daga shekara ta 2003, ana amfani da wannan fasahar nuni ga masu kunna kiɗan MP3.

A zamanin yau, fitaccen wakilin aikace-aikacen OLED shine allon wayar hannu.Allon OLED na iya nuna cikakkiyar bambanci na hoto, kuma hoton nuni zai zama mai haske da gaske.Saboda halaye na crystal ruwa, LCD allon baya goyan bayan lankwasawa.Sabanin haka, OLED na iya zama allon mai lankwasa.
