Compared with the traditional window glass products, this paper provides a transparent touch display window with transparent display technology and capacitive touch technology, which shows the feasibility of the future vehicle window products for the first time. This paper systematically studies the system integration and application of transparent display, touch panel as well as traditional window glass. It solved the laminate technology and packaging technology problems of the large size curvature laminate "rigid + soft + rigid" without the defects such as the laminate bubbles and display defect. The experimental results of the fatigue load test, thermal shock and vibration test, and the reliability test fully meet the specifications of rail transit.
