Lits'oants'o tsa LCD li sebetsa joang le mokhoa oa ho khantša skrine ea kristale ea metsi
1. Etsa qeto easkrine ea kristale ea metsiphepelo ea motlakase
Mohato oa bohlokoa ka ho fetisisa pele o tobetsa skrine ke ho fumana hore na motlakase oa skrine ke li-volts tse kae, ke hore, ke li-volts tse kae tseo re batlang ho li supa skrineng, le hore na e lumellana le lebokose la li-hardware.Haeba hardware e le 12V 'me skrine ke 5V, skrine e tla chesoa.E ka fumanoa ho litlhaloso tsa skrine ka kakaretso.
Tlhokomeliso: Motlakase oa phepelo ea matla skrineng le motlakase oa khanya ea skrineng ke li-module tse peli tse fapaneng.

Mehato ea ho qala PANEL: qala ka ho bulela phepelo ea matla ea PANEL, ebe u fetisetsa PANEL DATA, 'me qetellong u khantše lebone;tatellano ea ho koala e khutlisetsoa morao.Nako ea DELAY e behiloe ke software ea MCU, haeba boemo ba nako bo se botle, ho tla ba le skrine e tšoeu hang-hang kapa skrine.
Nka ho hlahisa LOGO e le mohlala.Qala ka ho bula skrine, lieha, 'me u romele LOGO.Ka nako ena, seo mosebelisi a se bonang se ntšo hobane lebone le ka morao ha le laetsoe.Ka mor'a hore LOGO e tsitse, khantša lebone la morao ho bona LOGO.
T2 ke nako ea ho tloha T-con power-on to LVDS data output, T3 ke nako ho tloha LVDS data output to backlight on, le T4 le T5 ke the power-down tatellano e tsamaellanang le T2 le T3, 'me T7 ke nako ea nakoana. pakeng tsa T-con khafetsa matla a ho sebetsa.Tatelano ea nako ea LVDS ea skrine e bohlokoa haholo.Haeba e sa hlophisoa hantle, ho tla hlaha mathata a kang sekirini se lerootho le skrini se setala se benyang.Bakeng sa litlhophiso tse khethehileng tsa parameter ka 'ngoe, ka kopo sheba lintlha tsa skrine.
Hangata motlakase oa backlight ke oona o ka sehloohong oa motlakase oa TV.Kamora hore phepelo e kholo ea motlakase e buloe, mokhatlo o hloka ho etsa letoto la ts'ebetso ea ho qala, kahoo T2 ka kakaretso e ka fihlela litlhoko.Nako ea lebone la morao hangata e hloka ho sebelisoa hammoho le nako ea LVDS, 'me ba na le paramente e tloaelehileng --- lets'oao la switjha la backlight.Ka nako ena, T3 e hloka ho hlophisoa ka mokhoa o utloahalang ho netefatsa hore lets'oao la switjha la backlight le khona ho fihlela litlhoko tsa nako tsa LVDS le nako ea lebone la morao.
Lits'oants'o tsa ho bulela skrineng sa kristale ea metsi le lits'oants'o tsa nako ea ho tima li eme ka tsela e latelang (ho tsoa ho sebopeho sa skrine):
1. Hardware
tlhahiso ea skrine ea kristale ea metsi
1. Motlakase o lokela ho lumellana le mefuta e mengata ea matla a matla a skrine ea pontšo
2. Hore na maqhubu a oache a hlahisoang ke potoloho ea kristale oscillator a nepahetse, ela hloko potoloho e sebetsang ea kristale oscillator, o hloka ho hlahloba PCB ho bona hore na mohala o nepahetse.
3. Lekola hore na tatelano ya ho seta botjha ya skrine e tsamaellana le tatelano ya ho seta botjha ya ditlhaloso tsa skrini.
4. Na ho na le phetoho leha e le efe ea waveform pineng ea ho qala skrineng ha o sebelisa matla, joalo ka SDA, SCL, CS kapa WR pins, haeba ho se joalo, u lokela ho hlahloba hore na software e hlophisitsoe ka pinana ea ho qala ea skrine.
tlhahiso ea skrine ea kristale ea metsi
1. Hore na HSYNC le VSYNC li na le waveform
2. Hore na phini ea data ea RGB kapa phini ea DATA e hlahisoa
2. Software
1. Lokisa pin ea taolo ea backlight ea skrine ea lcd 'me u e letse ho netefatsa hore skrini se ka khanya.
2. Hlophisa phini ea reset, pini ea ho qala SDA, SCL, CS kapa WR ea skrine sa lcd, le phini ea tlhahiso ea RGB kapa DATA.
3. Haeba skrine ea kristale ea metsi e hloka ho qalisoa ho eketsehileng, letsetsa khoutu ea ho qala ea skrine, e fanoeng ke mofani oa skrine.Haeba skrine ea kristale ea metsi e qalile ka hare, joale li-microcontrollers tse ling ha li hloke ho ngola tatellano ea ho qala skrine, ho seng joalo ho hlokahala hore u tobetse skrine ho latela boitsebiso bo fanoeng ke mofani oa skrine.
4. Qala skrine ea ho lokisa kristale ea metsi 'me u lokise liparamente tsa skrine.
