Zisebenza njani izikrini zeLCD kunye nendlela yokukhanyisa isikrini

Thatha ukubonisa iLOGO njengomzekelo. Qala uvule isikrini, ulibazise, ​​kwaye uthumele i-LOGO. Ngeli xesha, into ebonwa ngumsebenzisi imnyama kuba isibane esingasemva asivulwanga. Emva kokuba i-LOGO izinzile, vula isibane esingasemva ukuze ubone i-LOGO.

I-T2 lixesha elivela kwi-T-con power-on ukuya kwi-LVDS data output, i-T3 lixesha elivela kwi-LVDS data output to backlight on, kunye ne-T4 kunye ne-T5 ulandelelwano lwamandla-phantsi oluhambelana ne-T2 kunye ne-T3, kunye ne-T7 lixesha lekhefu. phakathi kwe-T-con ephindaphindiweyo amandla-on. Ukulandelelana kwexesha le-LVDS kwesikrini kubaluleke kakhulu. Ukuba ayicwangciswanga kakuhle, iingxaki ezifana neskrini esiluzizi kunye neskrini esiluhlaza esidanyazayo ziya kuvela. Kumaxabiso athile esicwangciso separameter nganye, nceda ubhekiselele kwimigaqo yesikrini.

Umbane we-backlight udla ngowona mbane uphambili weTV. Emva kokuba umbane oyintloko uvuliwe, intshukumo kufuneka yenze uluhlu lwemisebenzi yokuqalisa, ngoko i-T2 inokuhlangabezana ngokubanzi neemfuno. Ixesha lokukhanya ngasemva lidla ngokufuneka lisetyenziswe ngokudityaniswa nexesha le-LVDS, kwaye baneparamitha eqhelekileyo --- isiginali yokutshintsha isibane esingasemva. Ngeli xesha, i-T3 kufuneka icwangciswe ngokufanelekileyo ukuqinisekisa ukuba isignali yokutshintshela umva inokuhlangabezana neemfuno zexesha le-LVDS kunye neemfuno zexesha lokubuyela umva.

Umbane wescreen sekristale ekuvuleni amandla kunye nedayagramu yokucima umbane ihamba ngolu hlobo lulandelayo (ukusuka kubalulo lwesikrini):

1. Hardware

igalelo lesikrini sekristale elulwelo

1. Unikezelo lwamandla kufuneka luhambelane noluhlu lwamandla ombane wesikrini sokubonisa

2. Ingaba i-clock frequency eyenziwa yi-crystal oscillator circuit ichanekile, nikela ingqalelo kwi-crystal oscillator circuit esebenzayo, kufuneka ukhangele i-PCB ukuze ubone ukuba i-wiring ichanekile.

3. Khangela ukuba ukuseta ngokutsha ulandelelwano lweskrini luyahambelana na nolandelelwano lokuphinda lwenziwe lwemigaqo yesikrini.

4. Ngaba kukho naluphi na utshintsho lwe-waveform kwiphini yokuqalisa isikrini xa uvula amandla, njenge-SDA, i-SCL, i-CS okanye i-WR izikhonkwane, ukuba akunjalo, kufuneka ukhangele ukuba i-software iqwalaselwe kunye nephini lokuqalisa kwesikrini.

imveliso yekristale elulwelo screen 

1. Ingaba i-HSYNC kunye ne-VSYNC zinemo yamaza

2. Ingaba i-pin yedatha ye-RGB okanye i-PIN ye-DATA iphuma

2. Isoftware

1. Qwalasela iphini lolawulo lwesibane se-LCD yesikrini kwaye uyibize ukuqinisekisa ukuba isikrini sinokuqaqamba.

2. Qwalasela i-pin yokuseta kwakhona, i-pin yokuqalisa i-SDA, i-SCL, i-CS okanye i-WR yesikrini sokubonisa i-lcd, kunye ne-RGB okanye i-DATA yokukhupha iphini

3. Ukuba isikrini sekristale ye-liquid idinga ukuqaliswa okongeziweyo, biza ikhowudi yokuqalisa yesikrini, enikezelwa ngumthengisi wesikrini. Ukuba i-IC yesikrini se-crystal ye-liquid iqalwe ngaphakathi, ngoko ke ezinye ii-microcontrollers azidingi ukubhala ulandelelwano lokuqalisa isikrini, ngaphandle koko kuyimfuneko ukucofa isikrini ngokolwazi olunikezwa ngumthengisi wesikrini.

4. Qalisa i-liquid crystal screen debugging screen kwaye uhlengahlengise iiparameters zesikrini.
