Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional OLED display panels lack independent view control for two-dimensional and stereoscopic images, limiting their ability to provide personalized image display to users at different locations.
Innovation Solution
A display system incorporating a WOLED array, a lens layer, and a color filter layer, where the lens layer refracts light from the WOLED array to form images, and a video processor that converts video signals into light group control signals to activate specific light groups based on user location and display settings, allowing for directional light emission and efficient power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional OLED panels are used, then advantages such as lighter weight, lower thickness, higher brightness, and lower power consumption are achieved, but independent view control for two-dimensional and stereoscopic images is not provided
Solution Approach 1:
The OLED display panel is divided into multiple light groups (first light group, second light group, third light group) that can be independently controlled. Each light group corresponds to different viewing angles and can display different images simultaneously, enabling independent view control for two-dimensional and stereoscopic images while maintaining the advantages of conventional OLED technology
Solution Approach 2:
A lens layer is introduced as an intermediary component between the OLED light-emitting layer and the viewer. The lens layer includes multiple lens groups that refract light from different light groups to different viewing angles, enabling the OLED panel to provide directional light emission and independent view control without fundamentally changing the OLED structure
2Use of energy by moving object
If all light groups are activated for display, then complete image coverage is achieved, but power consumption increases
Solution Approach 1:
Different light groups are activated based on local requirements. The first light group is activated for two-dimensional images, while the second and third light groups are activated for stereoscopic images. This local activation strategy ensures that only the necessary light groups are powered on for each display mode, reducing overall power consumption while maintaining complete image coverage
Solution Approach 2:
The display system dynamically adjusts which light groups are activated based on the display mode and user needs. The controller can switch between activating only the first light group (for 2D images) or activating the first, second, and third light groups (for stereoscopic images), optimizing power consumption according to the actual display requirements
