Dual Display Sections for Transmissive Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transmissive display units, such as those using organic EL or liquid crystal devices, face challenges in maintaining visibility due to environmental conditions, where dark images become transparent in bright environments and bright images become transparent in dark environments, leading to reduced visibility of intended images.
Innovation Solution
A display system comprising a first display section for picture display and a second display section for dummy display, both performing transmissive displays based on a transmission picture signal that adjusts light transmission levels, allowing for improved visibility by managing light transmission levels in partial and non-partial image regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmissive display section is used to display images, then the display unit allows users to see both the displayed image and the background landscape, but the visibility of the displayed image decreases when the image brightness does not match the environment brightness
Solution Approach 1:
The display area is divided into two distinct display sections: a first display section for picture display and a second display section for transmissive display. This segmentation allows each section to be optimized for its specific function, with the first section ensuring image visibility and the second section maintaining background transparency.
Solution Approach 2:
Different regions of the display unit are assigned different optical properties. The first display section has properties optimized for image display, while the second display section maintains high transmissivity for background viewing. This local differentiation resolves the contradiction by ensuring that image visibility is maintained where needed without compromising overall transmissivity.
2Device complexity
If a single display section is used for both picture and transmissive display, then the device complexity is reduced, but the visibility control under varying environmental conditions deteriorates
Solution Approach 1:
The display system is segmented into two independent display sections that can be controlled separately. This allows the control unit to adjust the optical properties of each section independently based on environmental conditions, ensuring stable visibility performance across varying lighting conditions.
Solution Approach 2:
The display sections dynamically adjust their optical properties based on environmental lighting conditions. The control unit monitors the environment and adjusts the transmissivity and brightness of each display section in real-time, ensuring optimal visibility stability regardless of external conditions.

AI summary
Provided is a display unit that includes a first display section and a second display section. The first display section is configured to perform picture display and transmissive display. The picture display is based on a picture signal and performed on pixels in a partial region corresponding to a partial image part in a frame image represented by the picture signal, and the transmissive display is performed on pixels in a region other than the partial region. The second display section is provided behind the first display section, and configured to perform dummy display and transmissive display. The dummy display is performed on pixels in the partial region to display a dummy image that is one of a uniform image and a non-uniform image, and the transmissive display is performed on pixels in the region other than the partial region.
