LCD npo, hom, qhov zoo thiab qhov tsis zoo

Aug 11, 2017

1.STN LCD STN (super twisted nematic) muaj CSTN thiab DSTN cov ntsiab lus, zwm rau hom kev ntaus LCD, tsis muaj hwj huam noj, piv rau TFT-LCD npo hauv cov khoom nruab nrab ntev ntev, tab sis qhov no yog qhov nyiaj ntawm lwm yam ntawm kev ua tau zoo ntawm tus nqi. STN screen npo qhia tau tsawg dua tus npo TFT, tshwj xeeb tshaj yog nyob rau ob qho ntawm qhov ci thiab qhov ci ntawm qhov screenObviously, STN screen yog ib qho nyuaj rau siv sab nraum zoov thiab lwm yam hnub ci chaw. Lub vijtsam STN qhia tau qeeb qeeb qeeb, kwv yees li 200 tawm milliseconds, txoj kev taug yog qhov loj thaum ua si cov animations.

STN LCD

Hauv npo feem ntau tshwm nyob rau hauv qhov kev lag luam thaum ntxov ntawm cov xim tsawg kawg, MP3, MP4 cov khoom, ntau txhiab daus las ntawm 4096 MP3 xim npo Ntawm kaum siv cov lus qhia hauv LCD, cov khoom tshiab tsis tshua pom, ntseeg tom qab hnub ntawd yuav maj mam hloov.



2.TFT LCD (thin film transistor) TFT yog ib qho ua kom lub ntsej muag ua kua (Crystal Microfinance Screen) (Ib qho yooj yim) Hauv ib qho, tsim teeb tshwj xeeb rau hauv TFT-LCD substrate yuav rov qab "Active" tswj tag nrho cov cais pixels ntawm qhov screen, uas yog hu ua matrix TFT (active matrix TFT) Lub hauv paus chiv keeb ntawm qhov no tuaj yeem txhim kho cov lus teb lub sij hawm, lub sij hawm dav dav TFT sai dua, tsawg dua 80ms. Thiab vim hais tias TFT yog tus lej matrix LCD, uas tso cai rau lub sij hawm ntawm lub cim siv lead ua kua thiab yuav tsis rov zoo tam sim ntawd tom qab tam sim no tau ploj lawm. TFT kuj zoo dua qub rau STN LCD Lub phenomenon ntawm fuzzy flickering (dej yoj) zoo tuaj yeem tsim kho lub peev xwm ua si cov duab dynamic. thiab STN muaj kev txaus xim xim zoo nkauj, xim muaj peev xim thiab kev sib txawv dua li TFT. Qhov tsis zoo yog tias lub hwj huam tau siv zog thiab qhov nqi tsim nyog yog kev siab. TFT LCD LCD npo LCD yog lub ntsiab lus tseem ceeb tshaj plaws, ntau ntau daim ntaub ntawv tsis yog nyob hauv MP3, MP4 cov khoom, cov khoom hauv cov duab monitor, lub tshuab computer, lub xov tooj txawb, TV thiab lwm yam tshaj, kuv ntseeg tias peb yuav tsum tsis coj txawv txawv.


3.LTPS TFT-LCD LTPS ( Polysilicon tsis kub) TFT-LCD tshuab yog tsim los ntawm TFT LCD Ib tiam tshiab ntawm cov khoom siv tshuab siv los ntawm. Lub vijtsam LTPS yog los ntawm cov kabmob tshuaj ntsuab (silicon) (a-Si) TFT-LCD Panels yog qhia los ntawm laser ua. LTPS Laser khiav ntsuam xyuas txheej txheem yog kev siv laser melting kua siv lead ua kua thiab nws cov recrystallization, thiab a-Si TFT-LCD tsis yog crystalline piv nws yuav tsum pom tau hais hauv transistor sai npaum li 99 zaus ntawm cov hluav taws xob tshaj tawm tshaj, ua rau ntau dua kev daws teeb meem thiab muaj xim zoo nkauj. LTPS LCD muaj ntau tshaj li lwm yam Luam yawm suab hauv LCD hauv kev tsim pub rau me me transistors muab tso rau hauv lub LCD vaj huam sib luag. Yog li ntawd, nws txo qhov chaw nyob los ntawm lub peripheral Circuit Court ntawm qhov screen. Tus xov tooj ntawm cov khoom nyob hauv LTPS-LCD module yuav txo tau 40%, thaum lub qhov txuas txuas tau txo 95%, uas zoo heev txo cov khoom tsis ua haujlwm. Tsis tas li ntawd, LTPS npo npo siv tau zoo heev ntawm kev siv zog thiab kev ua haujlwm. Ntawm cov khoom tsis pom, LTPS Low temperature polysilicon tau ua kom muaj kev zoo, qhov kab rov tav thiab ntsug qhov pom tau li ntawm 170 degree, uas qhia lub sij hawm ntawm 12msThe ci ci, qhov sib txawv rau 500 zis, mus txog 500: 1. LTPSLCD Technology tau yug rau ntau xyoo, thiab muaj ntau yam zoo hauv kev ua tau zoo. Vim hais tias cov tsoos a-SI TFT tshuab los ntawm txoj kev loj hlob nyob rau hauv xyoo tas los lawm heev mature, thiab lub tshuab technology tsim LTPS TFT LCD npo siab tshaj qhov ntawm cov khoom tsim tau TFT-LCD, manufacturers muaj peev xwm ua khoom noj tsawg tsawg ntawm lub ntiaj teb tam sim no, yog li LTPS TFT LCD npo cov khoom siv thiab cov nqi qoob loo yuav yog cov neeg siab. Yog li ntawd, lub khw muag khoom siv tam sim no siv LTPS LCD tshuaj yog tsawg. Nyob rau xyoo 2004, Li Bao Mobile Technology tau siv cov qauv DP7010 MPEG4 neeg uas ua ntawv, yog siv 7 nti LTPS (LTPS) high-resolution widescreen (16: 9) npo, qhov siab tshaj plaws D1 (720 * 480) screen zaub yog zoo heev.


4.OLED OLED yog qhov tseem ceeb tshaj plaws ntawm lub vaj huam sib luag yog qhov tsis zoo, tsis zoo li TFT LCD backlight, yog li qhov pom kev thiab ci ntsa iab siab, thiab tsis muaj qhov teeb meem ntawm kev xav, tshwj xeeb tshaj yog cov uas tsis muaj kev tsav tsheb tsawg thiab kev siv hluav taws xob, qhov hnyav, nyias thooj, qauv yooj yim, qis dua, yog suav tias yog ib qho tseem ceeb tshaj plaws nyob rau hauv nees nkaum-thawj xyoo pua cog lus. OLED, zoo ib yam li LCD, yuav muab faib ua ob hom: nquag thiab tsis khov kho. Tam sim no dav siv rau hauv lub xov tooj txawb no yog AMOLED yam khoom siv lub teeb nruab nrab ntawm lub teeb tsa hluav taws xob, qhov sib txawv ntawm hom zaub thiab TFT LCD, ib zaj duab xis nyias transistor hauv txhua chav tsev ntawm OLED rov qab lub teeb nyob rau hauv raws li cov lus qhia ntawm lub teeb txais transistor. Thiab vim nws tsawg dhau lawm, cov cuab yeej OLED yuav tsum siab dua Kev khiav hauj lwm muaj zog. Xws li ib OLED nrog lub luminous siv ntawm 1000cd / m2 Nws qhov kev khiav hauj lwm voltage yog li 7 ~ 8V. Vim li cas thiaj li, OLED tsuas yog siv los ntawm qhov chaw them nqi thiab muaj lub siab dua kev txhaj tshuaj tam sim no. Yog li, tam sim no AMOLED tsis zoo li hluav taws xob txuag hauv kev xav. (manufacturers tam sim no: NOKIA, Motorola, Samsung)
