Backlit membrane switch iri nyore kuona uye kushanda munzvimbo ine rima.Vashandisi vanogona kuona zvakajeka chinzvimbo uye chimiro cheiyo switch, ichisimudzira chitarisiko chechigadzirwa kuti chiwedzere kutaridzika uye chazvino.Izvi zvinogona kuwedzera kukwezva kwechigadzirwa, kunatsiridza kuve nyore kwekushandisa, uye kuwedzera kurongeka kwekushanda.Iyo dhizaini inoshanduka yebacklit membrane switch inobvumira kugadzirisa zvinoenderana nekugadzirwa kwechigadzirwa zvinodiwa.Iyo backlight dhizaini inogona kubatanidzwa mukuonekwa kwese kwechigadzirwa kuti ienderane nezvinodiwa zvenzvimbo dzakasiyana, zvichiita kuti zvishandiswe zvakanyanya muzvigadzirwa zvakawanda.
Iyo yekudzosera kumashure kwe membrane switch inoda kutariswa kune zvinotevera zvakakosha zvinhu
Kusarudzwa kwebacklight source:Kutanga, iwe unofanirwa kusarudza yakakodzera backlight sosi.Sarudzo dzakajairika dzinosanganisira LED backlight uye EL backlight.LED backlight inowanzopa zvakanakira senge kupenya kwakanyanya, hupenyu hurefu, uye kugona kwesimba.Kune rimwe divi, EL backlight inozivikanwa nekutetepa kwayo, yakapfava, uye yakafanana mwenje emission maitiro.
Optical design:Iyo yakanyatsofungwa-out optical dhizaini yakakosha kuti uone nzvimbo, nhamba, marongero, uye chinhambwe chebacklight kubva kune mwenje sosi kuenda kune membrane switch uye mamwe ma parameter.Izvi zvinovimbisa kuti backlight inogona kuvhenekera zvakaenzana iyo yese membrane switch panel.
Kushandiswa kweChiedza Chekutungamira Plates:Funga kubatanidza ndiro yegwara mwenje (senge mwenje wegwara ndiro kana fiber optic) kuti ubatsire mukunangisa mwenje wakaenzana uye nekunatsiridza mavhenekera ekumashure.Iva nechokwadi chekuiswa kwakakodzera kwegaidhi remwenje ndiro kana backlight plate.Kana iwe uchida rubatsiro mune yakaenzana inotungamira mwenje uye nekuparadzira kupisa, nenzira kwayo isa zvinhu izvi panzvimbo yebacklight ye membrane switch kuti uvimbise yakajeka backlight mhedzisiro.Iyo yakakosha dhizaini yekugadzira membrane switch inobvumira kugovera kwakafanana kwechiedza kubva kune backlight sosi kumativi ayo ese.
Kusarudzwa kwezvinhu:Sarudza iyo yakakodzera backlight material inoenderana nezvinodiwa dhizaini kuti uve nechokwadi chekufambisa kwechiedza, mwenje conductivity, uye kugadzikana.Pamusoro pezvo, funga nezve kusimba, kugadzirisika, uye kushamwaridzana kwezvakatipoteredza kweiyo yakasarudzwa backlight zvinhu.
Circuit Design:Munguva yekutanga nhanho yekudzosera kumashure, zvakakosha kuronga nekugadzira iyo backlighting kuti uone nzvimbo, chimiro, uye zvinodiwa zvenzvimbo yekudzosera kumashure.Pamusoro pezvo, kugadzira kwakakodzera kubatanidzwa kwedunhu kunodiwa kuti uve nechokwadi chekuti backlight sosi inoshanda nemazvo uye inowana inodiwa backlight maitiro.Kushanda kwesimba uye kufunga nezvekuchengetedza kunofanirwawo kuverengerwa.
Yakazara dhizaini:Dhizaina chimiro chese chemembrane switch, kusanganisira kuiswa kweiyo backlight mudziyo, kugadzirisa nzira, uye tekinoroji yekugadzirisa.Sarudza iyo yakakodzera backlight uye inoenderana zvinhu zve encapsulation kuchengetedza backlight kubva kune yekunze nharaunda, kuve nechokwadi chekusimba uye kuenderana kweiyo backlight system uye membrane switch.
Kuedza uye kugadzirisa:Mushure mekubatanidza zvinhu zvekudzosera kumashure nezvimwe zvikamu zve membrane switch, kuyedzwa uye kugadzirisa kuchaitwa kuti uone kana iyo backlighting inosangana nezvinodiwa nedhizaini, sekupenya kufanana, kujeka, nezvimwe, uye kuve nechokwadi chekuti backlighting mhedzisiro uye basa zviri kushanda zvakanaka.Yekupedzisira debugging uye optimization ichaitwa kana zvichidikanwa.
Matanho ari pamusoro anotsanangura iyo general backlighting process ye membrane switch.Iyo chaiyo backlighting process inogona kusiyana zvichienderana nekugadzirwa kwechigadzirwa uye maitiro ekugadzira.Nekuita yakadzama yekudzosera kumashure maitiro uye akaomesesa emhando yekudzora nhanho, zvinokwanisika kuve nechokwadi chekuti membrane switch inowana yemhando yepamusoro backlighting mhedzisiro, pamwe nekugadzikana uye kuvimbika.
Membrane switching inogona kugadzirwa nenzira dzakasiyana dzekudzosera kumashure, uye nzira yakakodzera inosarudzwa zvichienderana nezvinodiwa zvechigadzirwa uye zvinoshanda zvinodiwa.Idzi dzinotevera dzimwe nzira dzakajairika dzekudzosera kumashure kune membrane switch
LED Backlight:LED (Chiedza Emitting Diode) backlight ndiyo imwe yenzira dzinoshandiswa zvakanyanya dzekudzosera kumashure.LED backlighting inopa mabhenefiti akadai sesimba rekushandisa, hupenyu hurefu, kupenya kwakanyanya kwakafanana, nezvimwe.Mwenje ye LED ine mavara akasiyana inogona kushandiswa kugadzira inoyevedza backlighting mhedzisiro.
EL (Electroluminescent) Backlighting:Electroluminescent (EL) backlighting yakapfava, yakatetepa, uye isina kupenya, zvichiita kuti ive yakakodzera kune curved membrane switch.EL backlighting inogadzira yunifomu uye yakapfava chiedza, uye inowanzoshandiswa mumashandisirwo anoda yakakwirira backlight kufanana.
CCFL (Cold Cathode Fluorescent Lamp) backlighting:CCFL backlighting inopa zvakanakira kupenya kwakanyanya uye yakanakisa kubereka kwemavara, ichiita kuti ive yakakodzera kune membrane switch inoda aya maficha.Zvisinei nekudzikira kwayo kukurumbira, CCFL backlighting ichiri kuwana niche musika mune mamwe maapplication ehunyanzvi.
Backlight Plate:Iyo backlight plate inogona kupetwa neakasiyana mwenje masosi (senge fluorescent mwenje, LEDs, nezvimwewo) kuti uwane iyo backlight mhedzisiro ye membrane switch.Ukobvu uye zvinhu zvebacklight plate zvinogona kusarudzwa zvichienderana nezvinodiwa kuti uwane kufanana uye kupenya kwebacklight.
Fiber optic backlighting:Fiber optic inotungamirwa backlighting itekinoroji inoshandisa optical fiber sechinhu chinotungamira chiedza kuunza mwenje sosi kumashure kwepaneru yekuratidzira, kuwana yunifomu backlighting.Fiber optic backlighting tekinoroji inowanzo shandiswa mumashandisirwo ayo anoda kuvheneka yunifomu munzvimbo dzakavharirwa, marongero anochinjika, kushanda nesimba, uye hushamwari kwezvakatipoteredza.
Kupenya-kupenya:Edge-kuvhenekerwa inzira inoshandiswa kuwana backlighting mhedzisiro nekuisa mwenje sosi pamucheto we membrane switch uye kushandisa mwenje refraction uye kufungisisa.Iyi tekinoroji inogona kuvhenekera zvakaenzana iyo yese backlit nzvimbo ye membrane switch.
Zvichienderana nezvakasiyana dhizaini zvinodiwa uye zvigadzirwa zvinoshanda zvinodiwa, unogona kusarudza yakakodzera backlighting nzira kuti uwane inodiwa backlight mhedzisiro ye membrane switch.Izvi zvinogona kuwedzera kukwezva kwekuona uye ruzivo rwemushandisi wechigadzirwa, kusangana nezvido zvemusika.
