Sida ay u shaqeeyaan shaashadaha LCD iyo sida loo shido shaashadda crystal dareeraha ah
1. Go'aansoshaashadda crystal dareeredanab sahayda
Talaabada ugu muhiimsan ka hor inta aanad riixin shaashadda waa in la ogaado inta volts ee danabka shaashadda, taas oo ah, inta volts ee shaashadda aan rabno inaan tilmaamno, iyo haddii uu ku habboon yahay Motherboard-ka hardware. Haddii qalabku yahay 12V, shaashaduna tahay 5V, shaashadda waa la gubi doonaa. Waxaa laga heli karaa tilmaamaha guud ee shaashadda.
Fiiro gaar ah: Korontada sahayda shaashadda iyo danab iftiinka dambe ee shaashadda waa laba qaybood oo kala duwan.

Tallaabooyinka bilowga PANEL: marka hore shid korontada PANEL-ka, ka dibna gudbi PANEL DATA, oo ugu dambeyntii shid laambadda; isku xigxiga xiritaanka ayaa rogan. Wakhtiga DELAY waxa dejiya software-ka MCU, haddii wakhtiga habayntu aanu fiicnayn, waxa jiri doona shaashad cad oo degdeg ah.
U soo qaado muujinta LOGO-ga tusaale ahaan. Marka hore shid shaashadda, dib u dhig, oo dir LOGO. Waqtigaan, waxa isticmaaluhu arko waa madow sababtoo ah nalka dambe ma daar. Kadib LOGO-gu xasilo, shid nalka dambe si aad u aragto LOGO-ga.
T2 waa wakhtiga laga bilaabo T-con power-on ilaa soosaarka xogta LVDS, T3 waa wakhtiga laga soo bilaabo wax soo saarka xogta LVDS ilaa iftiinka dambe ee shid, iyo T4 iyo T5 waa isku xigxiga awood hoos u dhigma T2 iyo T3, iyo T7 waa wakhtiga bareeg ah. Inta u dhaxaysa T-con soo noqnoqda korontadu. Isku-xigta wakhtiga LVDS ee shaashadda ayaa aad muhiim u ah. Haddii aan si sax ah loo dejin, waxaa soo bixi doona dhibaatooyin ay ka mid yihiin shaashada blur iyo shaasha cagaaran oo biliglaysa. Qiimaha dejinta gaarka ah ee halbeeg kasta, fadlan tixraac qeexida shaashadda.
Korontada dhabarka ayaa badanaa ah tamarta ugu weyn ee TV-ga. Ka dib markii korontada ugu muhiimsan la shido, dhaqdhaqaaqu wuxuu u baahan yahay inuu sameeyo hawlgallo taxane ah oo bilaw ah, sidaas darteed T2 guud ahaan waxay buuxin kartaa shuruudaha. Wakhtiga iftiinka dambe sida caadiga ah wuxuu u baahan yahay in lagu daro wakhtiga LVDS, waxayna leeyihiin halbeeg caadi ah --- calaamada beddelka iftiinka dambe. Waqtigan xaadirka ah, T3 waxay u baahan tahay in loo habeeyo si macquul ah si loo hubiyo in signalka beddelka iftiinka dambe uu buuxin karo shuruudaha wakhtiga LVDS iyo iftiinka dambe labadaba.
Shaashadda dareeraha ah ee kristanta-korka iyo jaantusyada waqti-daminta waa sida soo socota (laga bilaabo qeexitaanka shaashadda):
1. Hardware
galitaanka shaashadda crystal dareere
1. Korontadu waa in ay u hoggaansamaan qiyaasta korantada ee shaashadda bandhigga
2. Haddii inta jeer ee saacada ay dhaliso wareegga oscillator-ka crystal-ka ay sax tahay, fiiro gaar ah u yeelo wareegga oscillator-ka firfircoon ee crystal, waxaad u baahan tahay inaad hubiso PCB-ga si aad u aragto haddii xargaha uu sax yahay
3. Hubi in isku xigxiga dib-u-dejinta ee shaashadu uu waafaqsan yahay taxanaha dib-u-habaynta ee qeexitaanka shaashadda
4. Ma jiraan wax isbeddel ah oo mawjad qaabaysan ah oo ku yimi biinka bilowga ah ee shaashadda marka la shidinayo, sida SDA, SCL, CS ama biinanka WR, haddii kale, waxaad u baahan tahay inaad hubiso in software-ku ku habaysan yahay biinka bilowga ee shaashadda.
wax soo saarka shaashadda crystal dareere
1. Haddii HSYNC iyo VSYNC leeyihiin qaab mowjad ah
2. Haddi RGB data pin ama pin DATA ay soo baxdo
2. Software
1. Habee biinka kantaroolka iftiinka dambe ee shaashadda LCD-ga oo wac si aad u hubiso in shaashadu ay dhalaalayso
2. Habee biinka dib u dajinta, biinka bilawga SDA, SCL, CS ama WR ee shaashada lcd-ga, iyo RGB ama biinka wax soo saarka DATA
3. Haddii muraayadda dareeraha ah ee crystal-ka u baahan tahay bilawga dheeraadka ah, wac lambarka bilowga ee shaashadda, kaas oo uu bixiyo alaab-qeybiyaha shaashadda. Haddii shaashadda dareeraha ah ee IC-ga gudaha lagu bilaabay, markaa microcontrollers kale uma baahna inay qoraan taxanaha bilowga shaashadda, haddii kale waa lagama maarmaan in la riixo shaashadda iyadoo loo eegayo macluumaadka ay bixiso alaab-qeybiyaha shaashadda.
4. Bilow shaashadda wax-ka-qabashada shaashadda dareeraha ah oo hagaajiso cabbirrada shaashadda.
