Mene ne wani touchscreen?

A ikon yinsa na na'urorin hannu na girma a wani mataki taki. Ba duk da lokacin don samun used ga sharuddan 'alewa mashaya, darjewa da clamshell ", kamar yadda suka sabon. Alal misali, ko da buri na masu amfani, masana'antun suna tilasta su fassara duk touch fuska, yin watsi da hardware mashiga. Yanzu zabi na tura-button na'urorin, idan aka kwatanta da sensornikov, shi ne negligible. Kyau ko mara kyau - lokaci zai gaya, amma, mafi, haƙĩƙa, ka san abin da touchscreen kamata kowane.

Wannan sabon abu lokaci ne mai hade da biyu Turanci kalmomi - "Touch" da "Screen", wanda ma'anarsa za a iya karanta a matsayin "m ga tabawa." Duk wanda ya yi tambaya tambaya "touchscreen: shi" kawai ba ko da yaushe aikace-aikace na wannan fasahar. Na'urori tare da touch fuska birane mazauna ga kowace rana sau da yawa a rana :. Bank kwalaye da samun biya, reference tashoshi, mobile phones, da dai sauransu. A lokacin da ka danna a kan wani rabo na allo, akwai wani rajista na gaskiya daga m da handling, bisa ga lissafi mai tsauri a guje shirin. Yanzu da Internet yana da kuri'a na bayanai game da abin da yake cikin touchscreen. A gaskiya ma, cikin babban manufa na aiki da irin wannan fuska shi ne quite sauki da kuma shi zai iya fahimta ko da mutum nisa daga lantarki aikin injiniya. Duk da haka, ko da yake lokaci ne guda, amfani da Manufacturing fasahar kayyade da irin taba garkuwa.

Lalle ne, duk wanda yana da damar zabi wani zamani waya, kula da bayanin irin na tabawa - resistive ko capacitive. Duk wanda ya gane da tambaya "Wane ne touchscreen", sauƙi zabi mafi kyau model, saboda ya fahimci bambancin da ke tsakanin su.

Da zuciyar wani taba garkuwa ne matrix na ruwa crystal (a gaskiya, ayi a kananan kwafin duba). Tare da mayar da gefe haske ne haske emitting diodes, da kuma a gaban surface - yadudduka latching latsa (resistive fasahar) da kuma touch (capacitive bambancin).

A mutumin da ya koya da cewa irin wannan touchscreen, babu shakka, sanin cewa fiye da rabin na na'urorin amfani da resistive touch fuska. Wannan shi ne saboda da zumunta sauki na zane da kuma low price. Mai Sin "wayoyin salula na zamani", flooded kasuwa, an yi shi da resistive fasaha. Har ila yau, mahimmanci, wannan nau'in bayyana farko.

Na'urar haska bayanai na resistive irin kunshi biyu m roba faranti da lafiya raga na conductive abu zubar a kan LCD allon. Tsakanin su ne dielectric Layer (kuma m). Tun da image a kan Na'urar haska shi ne sauƙin gani, da shirin nuna wani hoto m dubawa. A mai amfani a mayar da martani ga bukatar da shirin, danna kan wani takamaiman batu na dubawa (kamar wani image button). A sakamakon haka, da roba insulator diverges, da kuma roba faranti a lamba. A halin yanzu amfani da wayoyin na daya daga cikinsu da dama a kan layin wutar sauran. Rikodi mai kula gano abin da ya faru na halin yanzu da kuma daidai da daidaita Grid batu kayyade latsa. Its tsarawa ake daukar kwayar cutar aiki shirin da, daidai da muhimmi Algorithms ake sarrafa.

sakamakon:

• sauki touch bai isa ba, kana bukatar ka danna shi.
• saboda redistribution da taro na insulating Layer bayan da lokaci da ake bukata k allo.
• yawan shanyewar jiki ga kowane yanki na allo da aka iyakance (daga 3 zuwa 35 Mill.).

In ba haka ba shirya capacitive fuska. A cikinsu uwa da babba surface na allo mai rufi da m-conductive shafi, da alaka da wayoyin a kusurwoyinsa. Lokacin da mutum touch (a manyan capacitance) zuwa irin wannan Layer, yanzu yayyo auku a cikin jiki. Tsarawa daga batu na lamba aka lasafta da kuma sarrafa. Touch fuska, ta yin amfani da wannan fasaha, za su iya jure fiye da miliyan 200. Touch.
