Problems solved by technology

[0003] At present, the multi-touch display technology mainly adopts infrared technology. The infrared touch technology is cost-effective and will not be disturbed by current, voltage and static electricity. The response speed is faster than the traditional capacitive touch technology, but the infrared touch display The screen is susceptible to errors caused by small foreign objects. The performance of the image is more suitable for various places with good environment and no infrared and light interference. In order to make the touch more light and smooth, reduce the impact of the external environment on multi-touch Influenced by the effect, the optical touch technology has begun to be developed and applied in a wider range. The optical image touch technology is adopted to realize multi-touch and various gesture recognition through the optical image touch technology, which effectively improves the touch sensitivity of the display screen. The currently used Optical image touch technology requires the cooperation of 2-4 cameras to effectively achieve multi-touch effects. With the development of technology and the development and application of new materials, it is necessary to look for sensing technology equipment and quick response systems that can make touch display systems more sensitive. , reduce production costs, and become the focus of research and development to meet market needs

Abstract

The invention discloses a graphene optical sensing technology-based multi-point touch display system. The system comprises two action capture modules, an intelligent image processing system and an intelligent display system. The action capture module is embedded in the intelligent display system; a light-sensing camera is arranged in the action capture module and connected with a high-sensitivitysensor; and the high-sensitivity sensor takes a composite graphene sensing film as a base, so that the light sensitivity and sensitivity of image capture are improved. The intelligent processing system comprises a preprocessing system and a data analysis system; and after an action is processed through the preprocessing system and the data analysis system, image identification and processing processes are finished. The intelligent display system comprises a display and an intelligent operation system. The sensitivity and transmission speed of the multi-point touch display system can be furtherimproved; accurate identification of the action is realized; and meanwhile, due to modularization of an action capture apparatus, the cost can be effectively reduced, the application of displays withvarious sizes can be flexibly adapted, and the optimization upgrading of various touch display devices is facilitated.
