•Iimbonakalo:
•I-Counter I-ICY:Iisekethe ezihlanganisiweyo eziqhuba imiqondiso yevidiyo kunye nokulawula umboniso.
•Izihloko:Izibuko zokudibanisa kwiphaneli ye-LCD (umzekelo, i-LVD, i-RGB) kunye nesixhobo esiphambili (umz, i-HDMI, VGA).
•Iisekethe zombane:Nika amandla afanelekileyo kwisibonakaliso kunye nesibane sayo ngasemva.
2. Iibhodi zokuqhuba
Injongo:Iibhodi zokuqhuba zilawula ukusebenza kwe-TFT LCD kwinqanaba le-Granter, egxile ekuqhubeni iiphikseli zomntu ngamnye kunye nokulawula ukusebenza komfanekiso.
•Iimbonakalo:
• I-IICS yomqhubi:I-chipps ekhethekileyo eqhuba iiphikseli ze-Tft kwaye ilawule amaxabiso okuhlaziya.
•UkuhambelanaIibhodi ezenzelwe ukusebenza kunye neephaneli ze-LCF ezithile kunye neemfuno zabo ezikhethekileyo.
3. Iibhodi
Injongo:Ezi bhodi ziququzelela unxibelelwano phakathi kwe-TFT LCD kunye nezinye izinto zenkqubo, zokuguqula imiqondiso phakathi kweempawu ezahlukeneyo.
•Iimbonakalo:
•Ukuguqulwa kwesiginali:Ukuguqula imiqondiso phakathi kwemigangatho eyahlukeneyo (umz., I-LVDs ukuya kwi-RGB).
•Iindidi zomdibaniso:Kubandakanya izinxibelelanisi ezahlukeneyo ukuba zihambelane zombini i-TFT ye-TFF kunye nenkqubo yokuphuma kwenkqubo.
4. Iibhodi zokugcina i-backlight
•Injongo:Ukunikezelwa kwenkanyezi kunye nokulawula ukukhanya kwe-tft LCD, ebaluleke kakhulu ekubonakaleni.
•Iimbonakalo:
•I-ACST YOKUGQIBELA IIC:Lawula ukukhanya kunye namandla okukhanya ngasemva.
•Iisekethe zoncedo lwaMandla:Nikeza i-voltage efunekayo kwaye okwangoku kwilitha ngasemva.
5. I-PCBS yesiko
•Injongo:I-PCBS-eyenzelwe i-PCB enziwe kakuhle kwi-TFF ye-LCD ye-LCD, ihlala ifunwa kwimiboniso eyahlukileyo okanye ekhethekileyo.
•Iimbonakalo:
•Uyilo olunemigangatho:Ubeko ngokweziko kunye nesekethe ukuhlangabezana neemfuno ezithile ze-TFT ye-TFF kunye nokusetyenziswa kwayo.
•Umdibaniso:Unokudibanisa umlawuli, umqhubi kunye nemisebenzi yolawulo lwamandla kwibhodi enye.
Ukuqwalaselwa okuphambili ngokukhetha okanye ukuyila i-PCB ye-tft lcd:
I-1. Ukudluliselwa kwemvume:Qinisekisa ukuba i-PCB idibanisa uhlobo lwe-TFT LCD ye-TFT LCD (umzekelo, i-LVD, i-RGB, MIPI DSI).
2. Isisombululo kunye nenqanaba lokuhlaziya:I-PCB kufuneka ixhase isisombululo se-LCD kunye nenqanaba lokuhlaziya ukuqinisekisa ukusebenza komdlalo ngokufanelekileyo.
3. Iimfuno zamandla:Jonga ukuba i-PCB ibonelela ngee-volloges ezichanekileyo kunye nemijikelezo kuzo zombini i-tft i-LCD kunye nelitha ngasemva.
4. Isinxibelelanisi kunye nobume:Qinisekisa ukuba ikhontrakthi kunye nendawo ye-PCB ihambelana neemfuno zomzimba kunye nombane ze-TFT LCD.
5. Ulawulo lobushushu:Cinga ngeemfuno ze-thermal ye-TFT LCD kwaye uqiniseke ukuba uyilo lwe-PCB lubandakanya ukwahlula-shintshashisa ubushushu.
Umzekelo wokusetyenziswa:
Ukuba udibanisa i-TFT ye-TFD kwiprojekthi yesiko, unokuqala ngeBhodi yokuLawulela i-LCD exhasa ukusonjululwa kwesibonisi sakho kunye nokujonga kwakhona. Ukuba ufuna ukusebenza okungakumbi okanye izinto zesiko, unokukhetha okanye uyile i-PCB yesiko elifaka i-communing thermally, isekethe elisebenzayo, kunye nezinxibelelanisi ze-TFT ze-TFFD.
Ngokuqonda ezi ntlobo ezahlukeneyo zebhodi ye-PCB kunye nokusebenza kwabo, unokukhetha okanye uyila i-PCB efanelekileyo ye-TFF yakho ye-LCF, ukuqinisekisa ukusebenza kunye nokusebenza kakuhle kwesicelo sakho.
IXESHA LOKUQALA: I-OCT-18 ukuya kwi-2024
