TFT 1.14 nti St7789v

Txhawm rau ua kom pom cov duab tsis txaus ntseeg, TFT-LCD qhia txog kev nce qib scan matrix teeb tsa nrog m × n dots. Thaum tsim lub voj voog tsav, koj yuav tsum xub xav txog tias cov kua siv lead ua kua electrolysis yuav ua rau cov khoom siv lead ua kua tsis zoo. Kom ntseeg tau tias lub neej ntev, AC tsav feem ntau yog siv. Cov qauv tsav tsheb uas tau tsim muaj xws li: voltage xaiv hom, ramp hom, DAC hom thiab analog hom, thiab lwm yam. Txij li thaum TFT-LCD yog tsuas yog siv nyob rau hauv phau computers, lub tsav Circuit Court yog roughly faib rau hauv: teeb liab tswj Circuit Court, fais fab Circuit Court, grey scale voltage Circuit Court, hom electrode tsav Circuit Court, cov ntaub ntawv kab tsav Circuit Court thiab chaw nyob kab tsav circuit ( rooj vag tsav IC).

Lub luag haujlwm tseem ceeb ntawm cov tsav tsheb uas tau hais los saum toj no yog: lub teeb liab tswj Circuit Court muab cov teeb liab digital, tswj cov teeb liab thiab moos teeb liab rau cov IC digital, thiab muab cov teeb liab tswj thiab moos teeb liab rau lub rooj vag tsav IC; lub zog hluav taws xob muab cov khoom siv hluav taws xob xav tau rau cov IC digital thiab rooj vag Tsav IC; lub grey voltage Circuit Court muab 10 grey voltages generated los ntawm lub digital tsav Circuit Court rau cov ntaub ntawv tsav tsheb feem; cov khoom siv hluav taws xob uas siv hluav taws xob siv hluav taws xob siv hluav taws xob ntau rau cov khoom siv hluav taws xob sib koom nrog rau pixel electrode; Cov ntaub ntawv kab tsav tsheb Circuit latches txhua 6-ntsis cov ntaub ntawv qhia thiab moos teeb liab ntawm RGB teeb liab xa los ntawm lub teeb liab tswj Circuit Court nyob rau hauv ib lub sij hawm. ua ntu zus thiab txuas ntxiv mus rau hauv. Tom qab ntawd cov ntaub ntawv tso tawm tau hloov mus rau hauv cov teeb liab analog los ntawm 6-ntsis DA converter, thiab tom qab ntawd Cov zis hluav taws xob hloov pauv cov impedance los muab cov ntaub ntawv kab ntawm LCD npo; Lub rooj vag tsav Circuit hloov lub moos teeb liab xa los ntawm lub teeb liab tswj Circuit Court los ntawm kev hloov pauv hloov pauv hloov pauv, hloov cov zis hluav taws xob mus rau ON / OFF voltage, thiab txuas ntxiv mus rau cov kua siv lead ua kua ntawm qhov screen. Thaum kawg, lub tshuab tsav hluav taws xob tau sib sau ua ke ntawm TAB (tsis siv neeg vuam hloov pauv hloov hluav taws xob) thiab txuas nrog lub LCD zaub siv ACF (anisotropic conductive film) thiab TCP (tsav Circuit Court saj zawg zog daim kab xev).
