Uburyo LCD ya ecran ikora nuburyo bwo kumurika ecran

Fata kwerekana LOGO nkurugero.Banza ufungure kuri ecran, gutinda, nohereze LOGO.Muri iki gihe, ibyo umukoresha abona ni umukara kuko itara ryinyuma ntirizima.LOGO imaze guhagarara, fungura itara ryinyuma kugirango urebe LOGO.

T2 nigihe cyo kuva T-con power-on kugeza LVDS yasohotse, T3 nigihe cyo kuva amakuru ya LVDS asohoka kugeza kumuri kumurongo, naho T4 na T5 nuburyo bukurikirana imbaraga zihuye na T2 na T3, naho T7 nigihe cyigihe. hagati ya T-con isubiramo imbaraga-kuri.Ibihe bya LVDS bikurikirana bya ecran birakomeye.Niba bidashyizweho neza, ibibazo nka ecran ya ecran na flash yicyatsi kibisi bizagaragara.Kubiranga igenamiterere ryihariye rya buri kintu, nyamuneka reba kuri ecran ya ecran.

Amashanyarazi yinyuma mubisanzwe niyo mashanyarazi nyamukuru ya TV.Nyuma yo gutanga amashanyarazi nyamukuru amaze gufungura, urugendo rugomba gukora urukurikirane rwibikorwa byo gutangiza, bityo T2 irashobora kuzuza ibisabwa.Igihe cyinyuma cyumucyo gikenera gukoreshwa mugihe cya LVDS, kandi bafite ibipimo rusange --- ibimenyetso byerekana urumuri.Muri iki gihe, T3 igomba gutegurwa mu buryo bushyize mu gaciro kugira ngo ibimenyetso byerekana ko urumuri rwanyuma rushobora kuzuza igihe cya LVDS nigihe cyo gusubiza inyuma.

Amazi ya kirisiti ya ecran ya power-on na power-off igishushanyo mbonera ni ibi bikurikira (uhereye kuri ecran ya ecran):

1. Ibyuma

Amazi ya Kirisitu yinjiza

1. Amashanyarazi agomba guhuza na voltage yumurongo wa ecran yerekana

2. Niba inshuro yisaha yatanzwe numuzunguruko wa kristu ya oscillator ari byo, witondere umuzenguruko wa kristal oscillator ikora, ugomba kugenzura PCB kugirango urebe niba insinga ari nziza

3. Reba niba gusubiramo urutonde rwa ecran bihuye no gusubiramo urutonde rwibisobanuro bya ecran

4. Haba hari impinduka ya flake kuri pin yo gutangiza ecran mugihe ikora, nka SDA, SCL, CS cyangwa WR pin, niba atariyo, ugomba kugenzura niba software yagizwe na pin yo gutangiza ecran.

Amazi ya kirisiti ya ecran 

1. Niba HSYNC na VSYNC bifite imiterere

2. Niba pin ya RGB cyangwa pin ya DATA isohoka

2. Porogaramu

1. Shiraho urumuri rugenzura pin ya ecran ya lcd hanyuma uhamagare kugirango urebe neza ko ecran ishobora kuba nziza

2. Shiraho reset ya pin, intangiriro pin SDA, SCL, CS cyangwa WR ya ecran ya lcd yerekana, hamwe na RGB cyangwa DATA isohoka pin

3. Niba ecran ya kristu ya ecran ikeneye iyindi ntangiriro, hamagara kode yo gutangiza ecran, itangwa nuwabitanze.Niba isukari ya kirisiti ya ecran ya IC yatangijwe imbere, noneho izindi microcontrollers ntizikeneye kwandika urukurikirane rwo gutangiza ecran, bitabaye ibyo birakenewe gukanda ecran ukurikije amakuru yatanzwe nuwatanze ecran.

4. Gutangiza ecran ya ecran ya ecran ya ecran hanyuma uhindure ibipimo bya ecran.
