Solution Overview
Problem
Conventional electronic display devices are often impractical for certain locations due to size and aesthetic concerns, and they suffer from restricted visibility and contrast issues in bright environments.
Innovation Solution
The use of display sheets with embossed mirror surfaces that can be mounted on various surfaces, including windows and walls, utilizing a short throw projector to provide improved visibility and brightness by reflecting light at different angles, allowing for increased fields of view and maintaining contrast in ambient light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If conventional electronic display devices are used, then display functionality is provided, but the devices are large and block views through windows
Solution Approach 1:
The patent uses a projection system that projects images onto a reflective surface (such as a window or wall) rather than using a conventional display device. The projection system includes a projector that casts images onto a reflective surface, which then reflects the images to the viewer's eye. This allows the display functionality to be copied onto any reflective surface in the environment, eliminating the need for large conventional display devices and enabling flexible placement in various locations.
Solution Approach 2:
The patent transitions from a two-dimensional display surface (conventional screen) to utilizing three-dimensional reflective surfaces in the environment (windows, walls, ceilings). By projecting images onto these existing three-dimensional surfaces and using their reflective properties, the system achieves display functionality without requiring dedicated display hardware in the traditional sense, thereby reducing size constraints and improving location adaptability.
2Adaptability or versatility
If conventional display devices are positioned in front of windows, then display functionality is provided, but the view through the window is blocked
Solution Approach 1:
The patent introduces a reflective surface (window, wall, or ceiling) as an intermediary between the projection system and the viewer. Instead of placing the display device directly in front of the window, the system projects images onto the reflective surface, which then reflects the images to the viewer's eye. This intermediary approach allows the window to serve dual purposes: as both the display surface and as a view-through element, eliminating the view obstruction problem.
3Illumination intensity
If conventional display devices are used in bright environments, then display functionality is provided, but contrast is low
Solution Approach 1:
The patent utilizes the reflective properties of surfaces to enhance image brightness and contrast in bright environments. By projecting images onto reflective surfaces (such as glass windows or metallic walls) and using their reflective characteristics, the system can maintain high contrast ratios even in well-lit conditions. The reflective surface acts as a secondary light source that enhances the perceived brightness and contrast of the projected images.
4Adaptability or versatility
If display devices are positioned to provide wide fields of view, then visibility is improved, but the devices occupy more space
Solution Approach 1:
The patent makes existing environmental surfaces (windows, walls, ceilings) serve multiple functions: they act as both the display surface for projected images and as structural elements of the room. This eliminates the need for dedicated display hardware that would occupy space, thereby achieving wide fields of view without increasing the area occupied by display devices.

Function Achieved in This Case
This solution enables electronic displays to be used in locations where traditional devices are impractical, offering improved visibility and brightness while maintaining contrast in bright environments, and reducing space consumption by positioning the projector close to the display sheet.

AI summary
Systems, methods, and computer-readable media are disclosed for display sheets with angled mirror surfaces. In one embodiment, an example display sheet may include a first layer and a plastic layer coupled to the first layer. The plastic layer may include a first portion with a first set of mirrors embossed on a surface of the plastic layer, where the first set of mirrors comprises a first tilt angle and a first roll angle. The plastic layer may include a second portion with a second set of mirrors embossed on the surface, where the second set of mirrors comprises a second tilt angle and a second roll angle. The display sheet may be configured to reflect light in a horizontal field of view and a vertical field of view with respect to a projector positioned to direct light at the display sheet.
