Matakan farawa na PANEL: da farko kunna wutar lantarki na PANEL, sannan watsa PANEL DATA, sannan a kunna fitilar; an juya jerin kashewa. Ana saita lokacin DELAY ta software na MCU, idan saitin lokacin bai yi kyau ba, za a sami farin allo ko allo nan take.
Ɗauki nuna LOGO a matsayin misali. Da farko kunna allon, jinkirta, kuma aika LOGO. A wannan lokacin, abin da mai amfani ya gani baƙar fata ne saboda ba a kunna hasken baya ba. Bayan LOGO ya tsaya, kunna fitilar baya don ganin LOGO.
T2 shine lokacin daga T-con power-on zuwa fitarwar bayanai na LVDS, T3 shine lokacin daga fitowar bayanan LVDS zuwa hasken baya, kuma T4 da T5 sune jerin saukar da wutar lantarki daidai da T2 da T3, kuma T7 shine lokacin tazara. tsakanin T-con maimaituwar kunnawa . Lissafin lokacin LVDS na allon ya fi mahimmanci. Idan ba'a saita shi da kyau ba, matsaloli kamar blur allo da walƙiya koren allo zasu bayyana. Don takamaiman ƙimar saiti na kowane siga, da fatan za a duba ƙayyadaddun allon.
Kayan wutar lantarki na baya yawanci shine babban wutar lantarki na TV. Bayan an kunna babban wutar lantarki, motsi yana buƙatar yin jerin ayyukan farawa, don haka T2 na iya cika buƙatun gabaɗaya. Lokacin hasken baya yawanci ana buƙatar amfani dashi tare da lokacin LVDS, kuma suna da siga gama gari --- siginar sauya hasken baya. A wannan lokacin, T3 yana buƙatar daidaitawa da kyau don tabbatar da cewa siginar sauya hasken baya na iya saduwa da lokacin LVDS da buƙatun lokacin hasken baya.
Allon wutar lantarki na ruwa crystal da zane-zanen lokacin kashe wuta sune kamar haka (daga ƙayyadaddun allon):
1. Hardware
shigar da allo crystal allo
1. Ya kamata wutar lantarki ta dace da kewayon ƙarfin wutar lantarki na allon nuni
2. Ko mitar agogon da kebul ɗin crystal oscillator ke samarwa daidai ne, kula da da'irar oscillator crystal mai aiki, kuna buƙatar bincika PCB don ganin idan wayoyi daidai ne.
3. Bincika ko jerin sake saitin allon ya yi daidai da tsarin sake saiti na ƙayyadaddun allon.
4. Shin akwai wani canji na waveform akan fil ɗin farawa na allon lokacin kunnawa, kamar SDA, SCL, CS ko WR fil, idan ba haka ba, kuna buƙatar bincika ko an daidaita software ɗin tare da fil ɗin farawa na allon.
ruwa crystal allo fitarwa
1. Ko HSYNC da VSYNC suna da tsarin motsi
2. Ko RGB data pin ko DATA fil yana fitarwa
2. Software
1. Sanya fil ɗin sarrafa hasken baya na allon nunin LCD kuma kira shi don tabbatar da cewa allon zai iya haske.
2. Sanya fil ɗin sake saiti, fil ɗin farawa SDA, SCL, CS ko WR na allon nuni na lcd, da fil ɗin fitarwa na RGB ko DATA.
3. Idan allon crystal na ruwa yana buƙatar ƙarin farawa, kira lambar ƙaddamarwa na allon, wanda mai samar da allo ke bayarwa. Idan an ƙaddamar da allon crystal na ruwa IC a ciki, to, sauran microcontrollers ba sa buƙatar rubuta jerin farawar allo, in ba haka ba ya zama dole don danna allon bisa ga bayanin da mai siyar da allo ya bayar.
4. Fara allon gyara allo na ruwa crystal kuma daidaita sigogin allo.
