Waba uzi itandukaniro rya LCD, LED na OLED?
Mugaragaza ecran yitwa kimwe mubintu bikomeye byavumbuwe mu kinyejana cya 20.
Ntabwo ari byinshi. Ubuzima bwacu bufite icyubahiro kubera isura.
Hamwe niterambere ryubumenyi nubuhanga, kwerekana ecran ntibikiri kugarukira mugukoresha televiziyo.
Ubucuruzi buniniLED yerekana ecrantangira gucengera mubuzima bwacu, nk'ahantu hacururizwa, muri sinema, birashobora kugaragara ahantu hatandukanye nko mu bibuga by'imikino yo mu nzu, kandi muri iki gihe, LCD, LED, OLED n'andi magambo y’umwuga nayo aratinda mu matwi, nubwo ari menshi abantu babavugaho, ariko abantu benshi bazi bike kuri bo.
None, ni irihe tandukaniro riri hagati ya Lcd 、 iyobowe na oled?
LCD,LED YEREKANAOLED
1, LCD
LCD ni ngufi kuri Liquid Crystal Yerekana mucyongereza.
Hariho cyane cyane TFT, UFB, TFD, STN nubundi bwoko. Imiterere yacyo irimo umupira wa pulasitike, umupira wibirahure, ikariso ya kole, substrate yikirahure, polarizer yo hejuru, icyerekezo cyerekezo, amazi ya kirisiti, uburyo bwa ITO ikora, aho itwara, IPO electrode na polarizer yo hepfo.
Dufashe urugero rwa LCD yamamaza nkurugero, ifata TFT-LCD izwi cyane, ikaba ari firime yoroheje ya transistor yamazi ya kirisiti yerekana. Imiterere yacyo yibanze nugushira isanduku ya kirisiti isukuye mubice bibiri bisa nkibirahure, shyira tristoriste yoroheje (aribyo TFT) kumirahuri yo hepfo, gushiraho akayunguruzo k'ibara hejuru yikirahure cyo hejuru, icyerekezo cyo kuzenguruka kwa molekile ya kirisiti igenzurwa nikimenyetso na voltage ihinduka kuri tristoriste yoroheje, kugirango ugere ku ntego yo kwerekana mugenzura niba urumuri rwa polarize ya buri pigiseli rwasohotse cyangwa ntirwoherezwe.
Ihame ryamazi ya kirisiti yerekana ni uko kristu yamazi izerekana urumuri rutandukanye munsi yumurimo wa voltage zitandukanye. Amazi ya kirisiti yerekana ecran igizwe nibintu byinshi byamazi ya kirisiti. Muri monochrome yamazi ya kirisiti yerekana ecran, kirisiti ya kirisiti ni pigiseli (igice gito gishobora kugaragara kuri ecran ya mudasobwa), mumabara yerekana ibara rya kirisiti yerekana ecran, buri pigiseli igizwe na kirisiti itukura, icyatsi nubururu. Muri icyo gihe, birashobora gufatwa ko hari 8-biti yanditswe inyuma ya buri kirisiti ya kirisiti, kandi agaciro k'igitabo kerekana urumuri rwa buri kimwe mu bice bitatu byamazi ya kirisiti, nyamara, agaciro k'igitabo ntigahinduka gutwara urumuri rwibice bitatu byamazi ya kristu, ariko bigerwaho binyuze muri “palette. Ntabwo bidashoboka guha buri pigiseli hamwe na rejisitiri ifatika. Mubyukuri, umurongo umwe gusa wo kwiyandikisha ufite ibikoresho. Iyandikisha ihujwe kuri buri murongo wa pigiseli hanyuma igashyirwa mubiri muri uyu murongo, gutwara imirongo yose ya pigiseli kugirango werekane ishusho yuzuye.
2, LED SCREENS
LED ni ngufi kuri Diode Yumucyo. Nubwoko bwa diode ya semiconductor, ishobora guhindura ingufu z'amashanyarazi imbaraga zoroheje.
Iyo electron ziyongereye hamwe nu mwobo, urumuri rugaragara rushobora kumurika, bityo rushobora gukoreshwa mugukora urumuri rusohora diode. Kimwe na diode isanzwe, urumuri rusohora urumuri rugizwe na pn kandi rufite kandi icyerekezo kimwe.
Ihame ryayo iyo voltage nziza yongewe kumucyo usohora diode, ibyobo byinjijwe mukarere ka N kuva mukarere ka P na electron zatewe mukarere ka P kuva mukarere ka N, muri microne nkeya hafi y’isangano rya PN, iruzuzanya. hamwe na electron mu karere ka N hamwe nu mwobo mu karere ka P kugirango bitange florescence yangiza.
Ingufu za electroni nu mwobo mubikoresho bitandukanye bya semiconductor biratandukanye. Iyo electron hamwe nu mwobo byiyongereye, ingano yingufu zasohotse ziratandukanye. Ingufu nyinshi zirekuwe, niko bigufi uburebure bwumucyo wasohotse. Bikunze gukoreshwa ni diode isohora itara ritukura, itara ryatsi cyangwa itara ry'umuhondo.
LED yitwa Igisekuru cya kane cyumucyo, gifite ibiranga kuzigama ingufu, kurengera ibidukikije, umutekano, ubuzima burebure, gukoresha ingufu nke, ubushyuhe buke, umucyo mwinshi, kutagira amazi, miniature, guhungabana, byoroshye gucana, urumuri rwinshi, urumuri rworoshye , nibindi, irashobora gukoreshwa cyane mubice bitandukanye nko kwerekana,LED yerekana, imitako, itara ryinyuma, itara rusange, nibindi.
Kurugero, LED yerekana ecran, Kwamamaza LED Mugaragaza, itara ryerekana ibimenyetso byumuhanda, itara ryimodoka, itara ryinyuma rya LCD, amatara yo murugo nandi masoko yamurika.
3, OLED
OLED ni ngufi kuri Diode ya Organic Itanga urumuri. Bizwi kandi nka laser yamashanyarazi yerekana, urumuri kama rutanga igice cya kabiri.
Iyi diode yavumbuwe muri laboratoire mu 1979 n'umwarimu w’umushinwa Deng Qingyun.
OLED igizwe na OLED yo hanze yerekana ibikoresho nibikoresho bisohora urumuri bifatanyijemo, harimo cathode, ibyuka bihumanya ikirere, urwego ruyobora, anode na base. Buri gice cyerekana OLED gishobora kugenzura kubyara urumuri rwamabara atatu atandukanye.
OLED yerekana ikoranabuhanga rifite ibiranga kwiyitirira urumuri, ukoresheje ibintu bito cyane byangiza umubiri hamwe nikirahure. Iyo hari umuvuduko w'amashanyarazi, ibyo bikoresho kama bizasohora urumuri, kandi impande zigaragara za ecran ya OLED yerekana nini, kandi irashobora kuzigama ingufu. Kuva mu 2003, ubu buhanga bwo kwerekana bwakoreshejwe kubakinnyi ba muzika MP3.
Muri iki gihe, uhagarariye porogaramu ya OLED ni ecran ya terefone igendanwa. OLED ya ecran irashobora kwerekana itandukaniro ryamashusho neza, kandi ishusho yerekana izaba nziza kandi nyayo. Bitewe nibiranga ibintu bisukuye, LCD ecran ntabwo ishigikira kunama. Ibinyuranye, OLED irashobora gukorwa mugice kigoramye.
Itandukaniro Muri Batatu
1, Ku ibara rya gamut
Mugaragaza OLED irashobora kwerekana amabara atagira iherezo kandi ntabwo ihindurwa n'amatara yinyuma, ariko LED Mugaragaza ifite umucyo mwiza no kureba impande zose.
Pixels ifite ibyiza byinshi mugihe yerekana amashusho yose-yirabura, kuri ubu, gamut yamabara ya ecran ya LCD iri hagati ya 72 na 92%, mugihe iyiyobowe na ecran iri hejuru ya 118%.
2, Ukurikije igiciro
LED ya ecran yubunini burenze inshuro ebyiri zihenze nka LCD mugice gito cya pigiseli ya pigiseli yayoboye urukuta rwa videwo, mugihe ecran ya OLED ihenze cyane.
3, Kubijyanye na tekinoroji ikuze yumucyo kandi idafite ikinyabupfura.
LED ya ecran ni nziza cyane kuruta LCD ya ecran na OLED mu mucyo kandi nta kinyabupfura, cyane cyane mubunini bunini bwayoboye urukuta rwa videwo rwo kwamamaza cyangwa gukoresha ibicuruzwa byo mu nzu bikoreshwa mu bucuruzi.
Mugihe LCD cyangwa OLED kubunini bunini bwa videwo yerekana amashusho akeneye gutondekwa, ikinyuranyo hagati yikibaho kizagira ingaruka kumikorere no kumva abareba.
4, Kubijyanye nimikorere ya videwo nu mfuruka yerekana
Ikigaragara cyihariye ni uko inguni igaragara ya ecran ya LCD ari nto cyane, mugihe ecran ya LED ishimishije mubikorwa no gukora neza hamwe niterambere ryikoranabuhanga ryerekanwe, byongeyeho, ubujyakuzimu bwa ecran ya LED burahagije cyane cyane muriYONWAYTECH igufi ya pigiseli yayoboye kwerekana igisubizo.
