Zera redhijitari rakaunza huwandu hwakawanda hwehunyanzvi hwekuratidzira. The TFT LCD skrini ndiwo mamwe ematekinoroji ayo akachinja indasitiri yemidziyo yemagetsi mumakore achangopfuura. Aya maratidziro matsva akaita kuti zvikwanisike kuti vagadziri vaunze mashandisirwo emushandisi, nguva dzekupindura nekukurumidza, uye mifananidzo yakapinza pamhando dzakasiyana siyana dzemidziyo, kubva kuTV kuenda kumafoni uye zvese zviri pakati.
Ichi chinyorwa chinokutungamira iwe munyika yeTFT LCD skrini. TFT inomirira Mutete Firimu Transistor Liquid Crystal Display (yakaonda-firimu transistor liquid crystal display), nepo LCD ichireva kushandiswa kwayo kwakawanda mumidziyo yemagetsi yakawanda sematerevhizheni, macomputer monitors, uye mapurojekita, pakati pezvimwe. Kana iwe uchiziva izvo zvekutanga zveaya maratidziro matekinoroji, iwe uri pakati ipapo.
Chii chinonzi TFT LCD skrini?
A TFT LCD skrini ndeye mutete firimu transistor electronic display (TFT). Izvi zvinoreva kuti seyakajairwa LCD skrini, iyi skrini inoshandisawo mvura yekristaro zvinhu. Nekudaro, musiyano wakakosha pakati peyakajairwa LCD neTFT LCD ndiyo nzira iyo mvura yekristaro zvinhu inoshandiswa muTFT LCD. Kusiyana neyakajairwa LCD skrini, iyo inoshanda nekutenderedza voltage pamvura yekristaro zvinhu nekudzima, TFT ine dijitari yekudzora dunhu. Iyi switch-type control inobvumira skrini kuratidza mifananidzo, kusanganisira zvinyorwa uye mifananidzo.
Mhando dzeTFT-LCDs
- inoshanda matrix: Active matrix TFT LCD inoratidza inoshandisa yakatetepa yemvura yekristaro zvinhu zvakaiswa pakati pezvikamu zviviri zvema electrode akaonda akajeka. Imwe firimu yakaonda inoonekera conductive inoiswa pakati peaya maelectrode uye inoita senge switch. Kana magetsi akaiswa pama electrode aya, mvura yecrystal material inomanikidzwa kushandura polarization mamiriro ayo, zvichikonzera shanduko mune yayo optical properties. Ichi chivakwa chinoshandiswa kuvhura nekudzima pixels kugadzira mufananidzo.
- Passive matrix: Mune passive matrix TFT LCD inoratidza, iyo yemvura crystal pani inoiswa sandwich pakati pemahwendefa maviri egirazi. Kana magetsi akaiswa pakati pemaelectrode maviri egirazi, maelectrodes anochinja kuita conductive state uye mvura crystal inoshanduka kubva kune imwe nyika kuenda kune imwe. Nenzira iyi, mapixels anodzorwa nepaneru pachayo.
Zvakanakira zveTFT LCDs
Pindai zvakanakira yeTFT skrini ndeiyi:
- yakanaka soda rate: Refresh rate inoreva kumhanya uko dhijitari skrini inogona kuratidza mifananidzo mitsva. Semuenzaniso, maTV mazhinji eCRT anoratidza mifananidzo pamwero wekuvandudza we 60 Hz. Izvi zvinoreva kuti mufananidzo unoratidzwa pascreen unovandudzwa ka60 pasekondi. Nematekinoroji matsva, akadai seLCDs, mwero wekuzorodza uyu wakaderedzwa kusvika pa244 Hz, zvinoreva kuti mifananidzo inoratidzwa pachiratidziro inozorodzwa chete ka244 pasekondi. Kazhinji, mwero wekuzorodza we60 Hz unodiwa kuti uunze mhando yemufananidzo inogamuchirika. Chidzitiro chine mwero wekuzorodza wakaderera pane icho chinotaridzika chakaoma uye chakasviba.
- Wide yekuona kona: Kusiyana nemaTV eCRT anoratidza mifananidzo ine kona yakamanikana yekuona, maLCD emazuva ano anokwanisa kuratidza mifananidzo ine yakakura yekuona kona. Izvi zvinoreva kuti iwe unogona kuona iyo mifananidzo nevaunoshanda navo uye shamwari kubva kune yakakura kona pasina iwo mufananidzo wemhando.
- Saizi yakaoma: Kuve akati sandara, saizi yacho yakanyanya compact uye yakatetepa kana ichienzaniswa neCRT skrini. Zvakare, maCRT haawanzo kuuya mumhando dzakasiyana siyana dzehukuru, ese makuru uye madiki anongori eLCD.
Kuipa kweTFT LCD skrini
Pakati pezvakashata zvezviratidziro izvi zvichienzaniswa nekare maCRT ndezvi:
- Mutengo: Mukana mukuru weLCD skrini ndeye mutengo wakaderera wekugadzira. Kana ichienzaniswa nemutengo wekugadzira weTFT, LCD inodhura zvishoma, zvichiita kuti ive yakanyanya kuwanikwa tekinoroji yekuratidzira kune ruzhinji. Nekudaro, nguva pfupi yadarika pave nekufambira mberi kwehunyanzvi hwe microlens izvo zvaita kuti zvikwanise kugadzira zvemhando yepamusoro zviratidziro nemutengo wakaderera wekugadzira.
- Kushandiswa: Nekuti dzinoda kudzoserwa.
Yakanakisa Arduino Inoenderana TFT Inoratidza
Ukaenda kutenga TFT skrini Kune mapurojekiti ako neArduino, heino mimwe mienzaniso yatinokurudzira:
Sezvauri kuona, iwo haana kudhura zvakanyanya uye anobvumidza iwe kuita akawanda mapurojekiti neArduino. Uye kwete izvozvo chete, iwe unogona zvakare kuvabatanidza kune mamwe mapurojekiti akasiyana, kusanganisira maSBC seRaspberry Pi. Versatility yakakwirira kwazvo, muganho ndiwo fungidziro yako.
