Description

GLASS ASSEMBLY AND WINDOW ASSEMBLY FIELD The present disclosure relates to the technical field of glass, in particular to a glass assembly with information display function and a window assembly using the glass assembly. BACKGROUND With the rapid development of automobile industry and the increasing demand of consumers for vehicle functions, lighting glass with decorative pattern has been widely valued by vehicle manufacturers and favored by the consumers. The pattern of the lighting glass is usually based on enamel or ink to form a pattern area on the glass surface, or a thin film with pattern is laminated on the glass, and incident light emitted by a light source is projected to the pattern area, so as to realize the lighting effect of pattern luminescence. The existing lighting glass usually changes the pattern shape and the light source to meet the requirements of the consumers. The patterns formed in these ways are fixed and can only achieve the effect of changing the color of the patterns. As a good medium to transmit information to the inside and/or the outside of the vehicle, a lighting glass is expected by the manufacturers and the consumers to bring more different feelings and experiences when the pattern is luminous. SUMMARY The object of the present disclosure is to propose a glass assembly which has a pattern and can dynamically display the pattern as required. When it is applied to a vehicle window glass, it can provide dynamic information that changes in real time to the inside and/or the outside of the vehicle, and present different and switchable pattern effect in an illuminated state, bringing a unique visual sense which cannot be obtained by single pattern or single color change, thus enhancing the consumer experience.
