Momwe zowonera za LCD zimagwirira ntchito komanso momwe mungayatsire chophimba

Tengani kuwonetsa LOGO monga chitsanzo.Yatsani chophimba choyamba, chetsani, ndikutumiza LOGO.Panthawiyi, zomwe wogwiritsa ntchito akuwona ndi zakuda chifukwa chowunikira chakumbuyo sichimatsegulidwa.LOGO ikakhazikika, yatsani nyali yakumbuyo kuti muwone LOGO.

T2 ndi nthawi yochokera ku T-con power-on to LVDS data output, T3 ndi nthawi yochokera ku LVDS data output to backlight on, ndipo T4 ndi T5 ndizomwe zimatengera mphamvu pansi zomwe zikugwirizana ndi T2 ndi T3, ndipo T7 ndi nthawi yapakati. pakati pa T-con mobwerezabwereza mphamvu pa .Mawonekedwe a nthawi ya LVDS pachithunzichi ndizovuta kwambiri.Ngati sichidakhazikitsidwe bwino, mavuto monga mawonekedwe osawoneka bwino ndi mawonekedwe obiriwira obiriwira amawonekera.Pamikhalidwe yokhazikika pagawo lililonse, chonde onaninso mawonekedwe azithunzi.

Mphamvu yamagetsi yakumbuyo nthawi zambiri imakhala mphamvu yayikulu pa TV.Mphamvu yayikulu ikayatsidwa, kayendetsedwe kake kamayenera kuchita zingapo zoyambira, kotero kuti T2 imatha kukwaniritsa zofunikira.Nthawi yowunikira kumbuyo nthawi zambiri imayenera kugwiritsidwa ntchito limodzi ndi nthawi ya LVDS, ndipo imakhala ndi chizindikiro chofanana --- chosinthira ma backlight.Pakadali pano, T3 ikuyenera kukonzedwa moyenera kuti zitsimikizire kuti chosinthira chowunikira chakumbuyo chimatha kukwaniritsa nthawi ya LVDS komanso nthawi yowunikira.

Zojambula zamagetsi zoyatsa ndi kuzizimitsa nthawi zili motere (kuchokera pachithunzichi):

1. Zida

liquid crystal screen input

1. Mphamvu zamagetsi ziyenera kugwirizana ndi mtundu wamagetsi amagetsi owonetsera

2. Kaya mafupipafupi a wotchi yopangidwa ndi crystal oscillator circuit ndi yolondola, tcherani khutu ku dera la crystal oscillator, muyenera kuyang'ana PCB kuti muwone ngati mawaya ali olondola.

3. Onani ngati kukonzanso kwa zenera kukugwirizana ndi kukonzanso kwa sewerolo.

4. Kodi pali kusintha kulikonse kwa mawonekedwe a ma waveform pa pini yoyambira ya zenera mukayatsa, monga SDA, SCL, CS kapena WR pini, ngati sichoncho, muyenera kuyang'ana ngati pulogalamuyo idakonzedwa ndi pini yoyambira pazenera.

liquid crystal screen linanena bungwe 

1. Kaya HSYNC ndi VSYNC ali ndi mawonekedwe

2. Kaya pini ya data ya RGB kapena pini ya DATA ndiyotuluka

2. Mapulogalamu

1. Konzani pini yoyang'anira backlight ya LCD skrini yowonetsera ndikuyitcha kuti muwonetsetse kuti chophimbacho chikhoza kukhala chowala.

2. Konzani pini yobwezeretsanso, pini yoyambira SDA, SCL, CS kapena WR ya skrini yowonetsera ya lcd, ndi pini yotulutsa RGB kapena DATA

3. Ngati chophimba chamadzimadzi chamadzimadzi chikufunika kuyambiranso, imbani nambala yoyambira pazenera, yomwe imaperekedwa ndi wopereka chophimba.Ngati mawonekedwe amadzimadzi a crystal screen IC adakhazikitsidwa mkati, ndiye kuti ma microcontrollers ena safunikira kulemba mndandanda woyambira pazenera, apo ayi ndikofunikira kuti mudutse chinsalu molingana ndi zomwe wapereka pazenera.

4. Yambitsani chophimba chamadzimadzi cha crystal screen ndikusintha mawonekedwe azithunzi.
