Kev sib raug zoo ntawm lub cev kev sib raug zoo nrog kev siv lub zog thaum nws los txog rau kev tsav tsheb.
Thaum peb tham txog cov khoom siv hluav taws xob nyob hauv LCD lub kaw lus peb pom muaj raws li txoj cai ntawm "Eighty- Nees nkaum txoj cai" uas mus zoo li no - uas backlight siv nyob ib ncig ntawm tsib caug mus rau yim caum feem pua ntawm tag nrho lub zog whilst lwm yam khoom yuav tsum tau muab faib los ntawm kev tsav tsheb circuits nrog rau peb cov phooj ywg qub -the Liquid up 3 Crystal Layer ' yuav ua rau { Kev cuam tshuam ntawm kev tsav tsheb ntau zaus nrog kev hwm rau nws cov txiaj ntsig siv hluav taws xob kuj qhia tau hais tias muaj ob qhov sib txawv.
Lub zog dynamic dominates tag nrho.
Fais fab kev siv ntawm Tsav Circuit Court yog ncaj qha Proportionate nrog zaus. Siv 3.5 nti TFT LCD ua piv txwv, thaum tsav tsheb zaus hloov ntawm 32 Hz mus rau 200 Hz, lub zog siv ntawm lub rooj vag tsav tsheb tuaj yeem nce 5-10 zaug. Nws tshwm sim vim yog kev sib koom ua ke ntawm MOSFETs hloov qhov poob thiab kev them nyiaj thiab tso tawm ntawm lub capacitors, thaum koj muaj kev ua haujlwm ntau zaus uas ua rau koj tau txais ntau cov transistors uas yuav tsum tau hloov mus rau qhov nrawm dua thiab muaj qhov pesky me me cab capacitance nqi tawm mus rau ob qho tib si ntawm cov electrodes ua ke tib lub sijhawm.
Qhov chaw siv hluav taws xob zoo li qub rau optimizaion
Cov ntaub ntawv siv lead ua kua lawv tus kheej kuj tuaj yeem pom cov lus teb qeeb (5ms r, 10ms poob). Thaum lub sij hawm tsav tsheb mus dhau qhov uas cov kua siv lead ua kua muaj peev xwm ua tau raws li qhov ua tau raws li nws cov kev txwv ceev, ib yam dab tsi uas kuv hu ua "kev tsav tsheb" tshwm sim: ib feem ntawm lub zog hluav taws xob no tau tig mus rau hauv tshav kub los ntawm qhov nyuaj npaum li cas nws tau rub nyob ib ncig ntawm cov me me hauv koj cov khoom uas txhais tau hais tias ntau cov khoom pov tseg ntxiv tau siv ntau dhau rau hauv koj lub cev yam tsis tau ua ntau yam haujlwm tseem ceeb hauv qab no. Raws li pom los ntawm kev sim cov ntaub ntawv, thaum tsav zaus yog 60 hertz, lub zog noj ntawm cov kua siv lead ua kua txheej ua rau kwv yees li 15% ; Yog tias peb nce nws tag nrho thiab nce zoo li sai npaum li cas nws yog 120 Hertz, daim duab ntawd dhia ncaj nraim mus rau ntawm 22 feem pua.
Kev siv txoj kev ntawm dynamic zaus modulation tshuab.
Lub algorithm ntawm Cov Ntsiab Lus AwarFrequency Kho.
Txheeb xyuas cov ntsiab lus nta, qhia cov ntsiab lus nta, thiab phim qhov kev tsav tsheb zoo tshaj plaws.
Cov ntaub ntawv thaum nws tsuas yog ib qho tseem thav duab zoo li qee yam ntawm cov twj paj nruag, yog tias muaj qee yam zoo li nws tau txo qis heev; peb tham 30-50 Hz. Tom qab peb siv txoj kev no lub zog noj ntawm lub tsav hluav taws xob sab rau qhov kev lag luam hmi system tau txo qis los ntawm tus nqi zoo, 42 feem pua, thaum tib lub sijhawm kuj txo cov nyhuv flicker los ntawm kev ncua sijhawm lcd tuav.
Dynamic Picture Compensation: Thaum peb tham txog ib yam dab tsi zoo li Video Saib Xyuas qhov twg nws tsis yog qhov zoo li qub tab sis hloov pauv thiab peb xav tau ib yam dab tsi los ua animated ib yam nkaus, peb yuav mus tom ntej nrog Frequency Graded Modulation System. Siv 1080P video playback piv txwv li, hloov ntawm kuv ncej ntawm 120Hz mus rau 80Hz thaum kwv yees ncej (P / B ncej), yog li nws zoo nkaus li du. Nyob rau hauv cov nqe lus ntawm kev ntsuam xyuas, nws tau ua pov thawj tias nws siv 18% tsawg zog dua li ua ntej tab sis tseem tswj tau qhov pom kev.

Tsim ntau-dimension FM qauv siv ALS, cov ntaub ntawv ntsuas kub.
Light intensity mapping. In very bright (>1000 lux) teeb tsa, tsa qhov tsav tsheb mus rau ntau dua 100 Hz kom pom tseeb dua. Hauv qhov tsaus ntuj (<50lux) circumstances, shift towards 40hz along with reduced-brightness setting. With the use of the TI OPT3001 sensor, we were able to achieve it and after implementation, a particular smart meter saw its day-to-day power consumption cut down by 0.8W.
Temperature them mechanism: viscosity ntawm cov khoom siv lead ua kua zoo sib txawv los ntawm temp. (-40 degree: 3x ntau viscous tshaj 25 degree). Peb kuj tseem tuaj yeem suav nrog tus pas ntsuas kub ntawm peb tus neeg tsav tsheb IC txhawm rau txhawm rau txhawm rau tsav qhov hluav taws xob thiab zaus raws li qhov xav tau. Piv txwv li thaum koj tab tom saib ib puag ncig ntawm -20℃qhov twg kuv yuav tso lub freq ntawm 60hz mus rau tej zaum 40hz tab sis nce lub zog tsav los ntawm 10%, uas yuav ua rau cov lus teb ceev tsis tau txo hwj chim los ntawm 15%.
Hardware Architecture Innovation
Lub multi-core driver archicture: Tus tswv-sldave driver IC tsim yog siv, static nd dyamic contnt re alloted o diferent cor sf rocssing. Qee lub tsheb ntsuas qhov system pom tau los ntawm cov qauv zoo li no: qhov taw qhia zoo li qub tau tsav ntawm 30Hz, dynamic navigation seem ua li ntawd ntawm 120Hz thiab vim li ntawd tag nrho cov kev siv hluav taws xob poob qis 27% piv rau ib qho kev xaiv tseem ceeb.
Lub asynchronous moos thev naus laus zis: Tshem tawm ntawm cov qauv kev tsav tsheb synchronous, siv lub moos cais rau txhua lub teeb liab RGB, moos teeb liab, thiab ua kom lub teeb liab. Kev sim nws tau raug pom kom txo qis lub zog siv hluav taws xob siv los ntawm kev tsav tsheb mus txog 35% nrog rau tshem tawm cov kev cuam tshuam hauv cov zaub vim yog moos offsets.
Case tsom xam rau daim ntawv thov nyob rau hauv ib tug industrial chaw.
Qhov chaw nres tsheb roj twj tso kua mis HMI system.
Hauv qee qhov Oilfield, lawv muaj 7 nti TFT-LCD raws li kev saib xyuas ntawm cov twj tso kua mis. Lub hauv paus siv lub zog tsav tas li 120HZ, nws yuav siv li 8.76kWh ib xyoos twg. Cov zaus hloov pauv los ntawm 120Hz taag mus rau dynamic zaus hloov kho:
Tus saib zoo li qub yog hom khoom siv nrog ntau zaus ntawm kev siv uas ua rau 75%, tab sis peb txo nws cov zaus los ntawm ib qho uas twb muaj lawm, uas yog 50.
Lub tswb animation siv li 20% ntawm nws, ntawm 120Hz.
Parameter teem interface accounting rau 5% yog upgraded los ntawm 150Hz.
Tam sim no peb tab tom ua qhov ntawd, peb qhov kev siv txhua xyoo tau poob qis dua li 5. 2 kilowatt-teev nrog peb pom qee yam nyob ib puag ncig ntawm plaub caug taw tes rau kev txuag tab sis tseem mus txog rau lub sijhawm teev tseg hauv GB / T 23863-011 Technical Condition Industrial Automation Instrument Display.
Chaw nres nkoj thawv Crane Instruments
Txhawm rau teb qhov chaw nres nkoj ib puag ncig nrog qhov chaw nres nkoj lub zog hluav taws xob hluav taws xob hluav taws xob lub tshuab hluav taws xob crane yuav siv cov kev hloov pauv zaus.
Base Zaus: 60Hz (tau ntsib ua haujlwm temp req rau -40 ~ +70 degree)
Dynamic Enhancement: Thaum peb pom tias lub zog txav ntawm peb lub cuab yeej nqa nrawm dua 0.5m / thib ob nws yuav luv luv mus txog 90Hz.
Anti-kev cuam tshuam hom: Thaum lub zaus hloov pauv pib ntawm EMI siab- lub sijhawm taw tes, nws poob rov qab tam sim ntawd mus rau 30 Hertz nrog ib qho ntxiv hauv lim ntawm Hardware.
Txoj kev npaj no yuav txhim kho EMC los ntawm 2 qib thiab txiav kev siv hluav taws xob los ntawm 18 feem pua raws li cov qauv tau teev tseg hauv IEEE C62.41.2-2002.
