Yuav ua li cas yog LCD?

Jul 12, 2017

LCD (kua siv lead ua zaub) yog lub technology siv rau qhia nyob rau hauv phau ntawv sau thiab lwm yam me me computers. Zoo li lub teeb-emitting diode (LED) thiab roj-ntshav technologies, LCDs cia qhia yuav tsum tau npaum li cas thinner tshaj cathode txoj sab ci raj (CRT) technology. LCDs haus tsawg npaum li cas hwj chim tshaj LED thiab gas-zaub qhia vim hais tias lawv ua hauj lwm nyob rau hauv lub hauv paus ntsiab lus ntawm thaiv cov hlab teeb es emitting nws.

Ib tug LCD yog ua nrog tog twg los ib tug passive matrix los yog ib tug active matrix zaub zaub daim phiaj. Lub active matrix LCD tseem paub raws li ib tug nyias zaj duab xis transistor (TFT) zaub. Lub passive matrix LCD muaj ib tug kab sib chaws ntawm conductors nrog pixels nyob rau txhua txhua lub tshuam nyob rau hauv daim phiaj. Ib tug tam sim no yog xa thoob plaws ob conductors rau hauv daim phiaj yuav tswj lub teeb rau tej pixel. Ib tug active matrix muaj ib tug transistor nyob rau ntawm txhua pixel tshuam, ntxiv tsawg tam sim no los tswj lub luminance ntawm ib tug pixel. Vim li no, tam sim no nyob rau hauv ib tug active matrix zaub yuav tsum hloov rau hauv thiab tawm ntau heev, kev txhim kho cov kev tshuaj ntsuam refresh lub sij hawm (koj nas yuav tshwm sim rau txav ntau ntseeg nkaws hla qhov screen, piv txwv li).

Ib txhia passive matrix LCD muaj dual PP, lub ntsiab lus uas lawv luam theej duab daim phiaj ob zaug tam sim no nyob rau hauv tib lub sij hawm uas nws muab rau ib tug scan nyob rau hauv tus thawj technology. Txawm li cas los, active matrix yog tseem muaj ib tug superior technology.
