Combination Display Merging Projector and Direct-View Screen

Solution Overview

Problem

The impracticality of having separate front projection and direct-view display devices due to increased costs and spatial limitations in household settings, where ambient light conditions and viewing preferences complicate the use of a single display technology.

Innovation Solution

A combination display apparatus featuring a direct-view display and a front projector that can operate in various modes, including direct-view, projection, and simultaneous modes, sharing video processing hardware to reduce costs and spatial requirements, with adjustable settings for ambient light and viewer preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate front projection display device and direct-view television are used, then viewing flexibility and adaptability to different conditions are improved, but cost and spatial requirements increase

Engineering Contradiction:

Improveviewing flexibilityVSAvoidspatial requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines a front projection display device and a direct-view television into a single integrated unit. The television is positioned in front of the projection device, allowing the same housing to accommodate both display technologies. This merging eliminates the need for separate spatial allocation for two distinct devices while maintaining the ability to switch between projection and direct-view modes based on ambient light conditions and viewing preferences.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated display device performs multiple functions within a single unit: it can operate as a front projection display for dark-room viewing, as a direct-view television for daytime or brighter environments, and potentially in combination modes. This multi-functionality provides viewing flexibility across different ambient light conditions and user preferences without requiring separate specialized devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate front projection display device and direct-view television are used, then viewing flexibility and adaptability to different conditions are improved, but cost increases
