Windshield Laminated Glass With Embedded Display and Hidden Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal displays mounted on windshield glass protrude into the car interior, causing visual disturbances for drivers and passengers.
Innovation Solution
Laminated glass with a built-in display, where the display is integrated between glass plates and an optically shielding layer at the peripheral edge, allowing it to be concealed from view, using ethylene-vinyl acetate copolymer interlayers for production without high-temperature treatments, and featuring dimensions that mimic rear view mirrors for comfortable viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid crystal display is mounted on the windshield glass surface to be visible to the driver, then the driver can easily make visual recognition of the display, but the display protrudes from the car-interior side of the windshield glass and serves as a disturbance to the driver or passenger
Solution Approach 1:
The display device is nested within the laminated glass structure by positioning it between the first and second glass plates, with the optically shielding layer concealing it from the car exterior side. This nesting approach allows the display to be integrated into the windshield without protruding into the car interior space, eliminating visual disturbance while maintaining visibility for the driver through the transparent glass structure.
Solution Approach 2:
The display is repositioned from a surface-mounted configuration (protruding into the third dimension of car interior space) to an embedded configuration within the laminated glass layers. By utilizing the layered structure of the windshield glass as the embedding dimension, the display achieves visibility without occupying car interior space, thus resolving the contradiction between visibility and visual disturbance.
2Shape
If the display is embedded within the laminated glass between glass plates, then the display does not protrude and does not disturb the driver, but the display must be disposed on the car-interior side of the optically shielding layer to maintain appearance
Solution Approach 1:
The windshield glass is segmented into multiple functional layers: the first glass plate, the display device, the optically shielding layer, and the second glass plate. This segmentation allows each component to fulfill its specific function - the display provides visibility information, the optically shielding layer conceals it from the exterior while allowing interior visibility, and the glass plates provide structural support and protection.
3Ease of operation
If the liquid crystal display is mounted on windshield glass using conventional methods, then the display is visible to the driver, but additional mounting structures (suction plates, arms, sun visors) are required increasing device complexity
Solution Approach 1:
The display device is merged with the laminated glass structure itself, eliminating the need for separate mounting structures. The display becomes an integral part of the windshield assembly, positioned between the glass plates and concealed by the optically shielding layer, thereby simplifying the overall device structure while maintaining visibility functionality.

AI summary
There is provided laminated glass including a display suited to windshield glass. The laminated glass 30 according to the present invention is configured by bonding, through substantially rectangular interlayers 16, 18 and 20, a substantially rectangular glass plate 12 and a substantially rectangular glass plate 14, which have the same sizes as each other. The laminated glass 30 has a plurality of rectangular organic EL displays 34, 36 and 38 as displays built at certain positions in the laminated glass 30. In other words, the laminated glass 30 according to the present invention suited to windshield glass is configured by interposing the organic EL displays 34, 36 and 38 between the interlayer 16 and the interlayer 20 disposed between the glass plate 12 and the glass plate 14.
