LCD kuratidza chidzitiro ndicho chinowanzo ratidza mudziyo muhupenyu hwedu hwezuva nezuva nebasa. Inogona kuwanikwa mumakomputa, terevhizheni, nharembozha, uye zvimwe zvakasiyana zvigadzirwa zvemagetsi. Iyo liquid crystal module haingopi yakakwira-mhando yekuona maitiro, asi zvakare inopa ruzivo kuburikidza nehukuru hwayo interface. Ichi chinyorwa chinotarisa pane chikuru interface uye chigadzirwa tsananguro yeTft Display.
Iyo huru interface yeTft Display inoitwa kuburikidza neakasiyana interface matekinoroji. Mamwe eakajairika interface matekinoroji anosanganisira RGB, LVDS, EDP, MIPI, MCU, uye SPI. Aya tekinoroji tekinoroji anoita basa rakakosha mukugadzira uye kushanda kweLCD skrini.
Iyo RGB interface ndeimwe yeakajairika LCD kuratidza skrini. Inogadzira mifananidzo kubva kumapikiseli emavara matatu: tsvuku (R), girini (G), uye bhuruu (B). Pixel yega yega inomiririrwa nemusanganiswa wakasiyana weaya matatu mavara ekutanga, zvichikonzera kuratidzwa kwemavara emhando yepamusoro. RGB interfaces inowanikwa pane akawanda echinyakare makomputa monitors uye terevhizheni skrini.
Iyo LVDS (Yakaderera Voltage Differential Signaling) interface ndeye yakajairika interface tekinoroji inoshandiswa kune yakakwirira-resolution liquid crystal modules. Iyo yakaderera-voltage musiyano wechiratidzo tekinoroji interface. Nzira yekufambisa yedhijitari yevhidhiyo yedhijitari yakagadziridzwa kuti ikunde kukanganisa kwekushandiswa kwesimba rakanyanya uye yakakwira EMI electromagnetic kukanganiswa kana uchitumira Broadband yakakwira bit reti data padanho reTTL. Iyo LVDS inobuda interface inoshandisa yakadzika kwazvo voltage swing (inenge 350mV) kuendesa zvakasiyana data pamatanho maviri ePCB kana maviri tambo dzakaenzana, kureva, yakaderera-voltage musiyano wechiratidzo chekufambisa. Iko kushandiswa kweLVDS inobuda interface inobvumira masaini kuti afambiswe pamitsara yePCB mitsara kana tambo dzakaenzana pachiyero chemazana akati wandei Mbit/s. Nekuda kwekushandisa yakaderera voltage uye yakaderera ikozvino nzira dzekutyaira, yakaderera ruzha uye yakaderera simba kushandiswa kunowanikwa. Inonyanya kushandiswa kuwedzera kumhanyisa data kwechidzitiro uye kuderedza kukanganiswa kwemagetsi. Nekushandisa iyo LVDS interface, LCD skrini inogona kufambisa yakawanda yedata panguva imwe chete uye kuwana yepamusoro yemhando yemifananidzo.
Iyo EDP (Embedded DisplayPort) interface chizvarwa chitsva cheTft Display interface tekinoroji yemalaptops uye mahwendefa. Iyo ine zvakanakira yakakwira bandwidth uye yakakwirira data data rate, iyo inogona kutsigira yakakwirira resolution, yakakwirira yekuzorodza mwero uye yakapfuma kuita kwemavara. Inonyanya kushandiswa kuwedzera kumhanyisa data kwechidzitiro uye kuderedza kukanganiswa kwemagetsi. Nekushandisa iyo LVDS interface, LCD skrini inogona kufambisa yakawanda yedata panguva imwe chete uye kuwana yepamusoro yemhando yemifananidzo. Iyo EDP interface inogonesa iyo LCD kuratidza skrini kuti ive nani ekuona maitiro panharembozha.
MIPI (Mobile Indasitiri processor Interface) yakajairika interface chiyero chenharembozha. Iyo MIPI interface inogona kufambisa yepamusoro vhidhiyo uye data yemifananidzo ine yakaderera simba rekushandisa uye yakakwirira bandwidth. Inoshandiswa zvakanyanya muLCD skrini yemafoni emafoni akadai sema smartphones uye mahwendefa.
Iyo MCU (Microcontroller Unit) interface inonyanya kushandiswa kune imwe yakaderera-simba, yakaderera-resolution Tft Displays. Inowanzoshandiswa mumidziyo yemagetsi yakapfava yakadai sema calculator uye smart wachi. Iyo MCU interface inogona kunyatso kudzora kuratidzwa uye mabasa eLCD kuratidza skrini uku uine yakaderera simba rekushandisa. Data bit transmission inosanganisira 8-bit, 9-bit, 16-bit uye 18-bit. Izvo zvinongedzo zvakakamurwa kuita: CS/, RS (kunyoresa kusarudzwa), RD/, WR/, uyezve mutsara wedata. Zvakanakira ndezvi: zviri nyore uye zviri nyore kutonga, hapana wachi uye masaini masaini anodiwa. Izvo zvakashata ndezvekuti: inoshandisa GRAM, saka zvakaoma kuwana skrini hombe (QVGA kana pamusoro).
SPI (Serial Peripheral Interface) iri nyore uye yakajairika interface tekinoroji inoshandiswa kubatanidza mamwe makomputa madiki, senge smart wachi nemidziyo inotakurika. Iyo SPI interface inopa kukurumidza kumhanya uye diki pasuru saizi kana uchitumira data. Kunyangwe iwo mhando yekuratidzira yakadzikira, yakakodzera kune mamwe maturusi asina zvakakwirira zvinodikanwa zvekuratidzira maitiro. Inogonesa iyo MCU uye akasiyana siyana emidziyo kuti ataure nenzira ye serial kuchinjanisa ruzivo. SPI ine marejista matatu: rejista yekudzora SPCR, rejista yemamiriro SPSR uye rejista yedata SPDR. Peripheral midziyo inonyanya kusanganisira network controller, Tft Display mutyairi, FLASHRAM, A/D converter uye MCU, nezvimwe.
Kupfupisa, iyo huru interface yeLCD kuratidza skrini inovhara akasiyana siyana matekinoroji akadai seRGB, LVDS, EDP, MIPI, MCU uye SPI. Yakasiyana interface matekinoroji ane akasiyana maapplication mune akasiyana Tft Displays. Kunzwisisa hunhu uye mashandiro eLCD screen interface tekinoroji ichatibatsira kusarudza liquid crystal module zvigadzirwa zvinoenderana nezvatinoda, uye kushandisa zvirinani uye kunzwisisa musimboti wekushanda weLCD skrini.
