Abstract:

An infrared touch component of airborne large-screen display was designed according to the demand of airborneequipment’s human-computer interaction. Some technologies such as bidirectional infrared transceiver, dynamic addressscanning, environmental light scanning and multi-touch scanning were used, and the infrared touch component had thecharacteristics of high resolution, high accuracy, high reliability, anti interference of direct sunlight and multi-touch sup.port. The performance test results showed that the component fully met the human-computer interactive need of airbornelarge-screen display.
