4.3 Nti 480 × 320 RGB Interface TFT LCD Screen

Lub hauv paus ntsiab lus ntawm cov kua siv lead ua kua yog ua raws li cov yam ntxwv uas lub teeb xa tawm ntawm cov kua siv lead ua kua hloov nrog qhov loj ntawm qhov voltage qhia los ntawm nws. Thaum lub teeb dhau los ntawm sab sauv polarizer, nws dhau los ua linearly polarized lub teeb. Cov kev taw qhia polarization yog ua raws li kev co kev taw qhia ntawm polarizer, thiab ua raws li kev txiav txim ntawm cov kua siv lead ua kua molecules nyob rau sab sauv thiab qis iav substrates. Thaum lub teeb dhau los ntawm cov kua siv lead ua kua txheej, lub teeb linearly polarized yog decomposed rau hauv ob kab teeb ntawm lub teeb vim refraction los ntawm cov kua siv lead ua kua.Thiab vim hais tias ob kab teeb ntawm lub teeb propagate ntawm qhov sib txawv speeds (nrog rau tib theem), thaum ob kab teeb. ntawm lub teeb ua ke, kev co kev taw qhia ntawm lub teeb vibrating yuav inevitably hloov. Lub teeb dhau los ntawm cov kua siv lead ua kua yog maj mam distorted. Thaum lub teeb mus txog qhov qis polarizer, nws cov kev taw qhia qhov muag pom kev vibration yog twisted los ntawm 90 degrees thiab tseem zoo ib yam nrog cov kev vibration ntawm lub polarizer hauv qab. Nyob rau hauv txoj kev no, lub teeb dhau los ntawm lub polarizer qis los ua ib qho chaw kaj. Tom qab siv qhov hluav taws xob, cov kua siv lead ua kua yog taw qhia nyob rau hauv qhov kev txiav txim ntawm qhov hluav taws xob thiab qhov cuam tshuam ploj. Lub sij hawm no, lub teeb linearly polarized uas dhau los ntawm sab sauv polarizer tsis rotates nyob rau hauv cov kua siv lead ua txheej thiab tsis tuaj yeem dhau los ntawm cov polarizer qis dua los ua ib qho chaw tsaus. Nws tuaj yeem pom tau tias cov kua siv lead ua kua nws tus kheej tsis tawm lub teeb thiab tuaj yeem pom nyob rau hauv qhov kev hloov pauv ntawm lub teeb pom kev sab nraud. Thaum lub sij hawm tag nrho cov txheej txheem tso saib, cov kua siv lead ua kua ua lub zog tswj lub teeb valve.

Lub hauv paus ntsiab lus ua haujlwm ntawm TFT-LCD tuaj yeem piav qhia luv luv li: thaum lub rooj vag rau pem hauv ntej voltage ntau dua li qhov siv hluav taws xob, lub qhov hluav taws xob ntws tawm tau qhib, thiab thaum lub rooj vag pem hauv ntej voltage yog sib npaug rau 0 lossis qhov tsis zoo. voltage, qhov ntws-qhov chaw electrode raug muab tua. Lub qhov dej electrode txuas nrog ITO pixel electrode, lub hauv paus electrode txuas nrog rau kab (kem electrode), thiab lub rooj vag electrode txuas nrog lub rooj vag kab (kab electrode). Qhov no yog lub hauv paus ntsiab lus ua haujlwm yooj yim ntawm 4.3-inch 480 × 320 RGB interface TFT LCD npo.
