Inkampani yethu
I-Hangzhou Grahowlet Technology ngumhlinzeki wesevisi obanzi we-capacide Touch screen module kanye ne-TFT LCD isibonisi sezimboni ezahlukahlukene. Ukuze uhlangabezane nezidingo ezihlukile zamakhasimende omhlaba wonke, i-hongxiao enikezela zonke izinhlobo zezakhiwo zomkhiqizo audas G + g, g + f (g + f (g + f (g + f (g + f (g + f (g g + f (g + f (g + f (g + f Sihlinzeka ngezixazululo ezifana nalo lonke izidingo zesikrini sokuthinta amakhasimende futhi sakhe imikhiqizo ngokususelwa kubuchwepheshe obuningi. Sizibophezele ukunikela ngamakhasimende omhlaba ngemikhiqizo esezingeni lokuqala kanye nezinsizakalo zobuchwepheshe eziqeqeshiwe kwizimboni zokuthinta. Imikhiqizo yethu inokuqina okuphezulu kanye nokulwa nokungaphazanyiswa futhi isetshenziswa ezimbonini ezahlukahlukene ngezimo eziyinkimbinkimbi nezinzima.
Q & a
Q: Yimuphi umgomo wesikrini sokuthinta se-capacitive ukufezekisa ukuthinta okuningi?
A: Lapho umunwe uthinta isikrini se-capacive, kuthinta ukuhlanganiswa phakathi kwalezi zinto ezimbili ze-electrodes eduzane nephuzu lokuthinta, ngaleyo ndlela kuguqule amandla phakathi kwama-electrodes amabili. Lapho uthola amandla ahambisanayo, ama-electrodes alandela ngokulandelana aphuma ngokulandelana kwama-pulse pulse amasiginali, nawo wonke ama-electrodes amade athola amasiginali ngasikhathi sinye, ukuze amanani we-capmacitance awo wonke ama-electroves alolu mbumbulu wendiza enezici ezimbili zokwenza isikrini sonke. Ngokwemininingwane yokushintshana-ntathu yama-capcacitance change yesikrini sokuthinta, izixhumanisi zephuzu ngalinye lokuthinta lingabalwa. Okungukuthi, izixhumanisi zangempela zamaphoyinti amaningi zingabalwa ukubona ukuthintwa okuningi;
Q: Mayelana nesikrini se-capacive esisisebenzisayo manje, inkinga yokuphazamiseka kwamandla kagesi imbi kakhulu. Yini okufanele siyenze ukuqeda ukuphazamiseka kokunikezwa kwamandla?
Ngaphandle kokuskena imvamisa yokuhlola ukugwema imvamisa yomsindo wokuhlinzekwa kwamandla, thuthukisa isilinganiso se-Signal-to-Noise yesikrini? Ingabe ikhona enye indlela? A: Ukubona kuzo zonke izimo zamanje, ukuphazanyiswa kwamandla kwamandla kugxilwe kakhulu ku-TP enkulu (7inch noma ngaphezulu), futhi sinezixazululo ezilandelayo: (1) Khetha ukuhanjiswa kwamandla okukhwalithi. Lokhu kubaluleke kakhulu futhi indlela ephumelela kakhulu futhi eyisisekelo yokuxazulula ukuphazamiseka kwamandla; (2) imvamisa ye-hopping. Sebenzisa i-Spectrum Analyzer ukuthola indawo lapho amandla ajwayelekile wokuphazamiseka we-adaptha amancane, bese usetha imvamisa ye-TX scan kule ndawo ngokusebenzisa izilungiselelo zesoftware, ezingalawula ngempumelelo ukuphazamiseka. Uma kunokuphazamiseka ebhendini eligcwele imvamisa, kunconyelwa ukulahla i-adaptha; (3) thuthukisa isiginali ku-umsindo isilinganiso. Ekwakhiweni kokuqala kwe-TP (7.0inch noma ngenhla), cabanga ukusebenzisa impahla ethathwayo engaphansi kwe-RX yesiteshi se-RX futhi usebenzisa ukwakheka komkhondo osuselwa kabili. Zama ukulawula konke ukumelana kwesiteshi ngaphakathi kwe-10K, okungalawula ngempumelelo ukuphazamiseka kwamandla. ; (4) Kungenzeka futhi ukuthi ushintshe ishaja, wandise ukuhlunga kwe-algorithm, futhi wamukele i-cypress, i-eeti, amacebo we-ILI ngokusebenza okunamandla okulwa nokuphazamiseka.
