Display Panel Transmissive Mode Controller Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display devices with transmissive modes are hindered by controllers disposed behind the display panel, obstructing transmittance and complicating installation due to separate housing requirements.
Innovation Solution
The image display device configures a controller within a lower shelf board that projects rearward, allowing the display panel to operate in a transmissive mode without obstructing the view and simplifying installation by integrating the controller within the device's housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller is disposed behind the display panel, then the controller can control the display panel operations, but the controller obstructs the transmittance and blocks the view through the display panel
Solution Approach 1:
The controller is rotated 90 degrees around the normal direction of the display panel, changing its orientation from parallel to perpendicular. This dimensional change allows the controller to be positioned behind the display panel without blocking the light path, as it now extends in the vertical direction rather than horizontally across the light transmission path.
Solution Approach 2:
The controller is divided into multiple sections: a first section disposed behind the display panel and a second section extending downward from the first section. This segmentation allows the controller to be distributed in space, with only a minimal portion (the connection area) located behind the display panel, thereby reducing obstruction to light transmittance while maintaining full control functionality.
2Reliability
If the controller is disposed behind the display panel in a separate housing, then the controller can be isolated, but the installation becomes complicated and the device structure is complex
Solution Approach 1:
The controller is integrated directly into the housing structure of the display device, merging two previously separate components (controller housing and display housing) into one unified structure. This eliminates the need for separate controller housings and complex inter-housing connections, simplifying the overall device structure while maintaining proper controller isolation and functionality.

Function Achieved in This Case
Enables effective use of the display panel in transmissive mode by minimizing the controller's impact on the field of view and simplifying installation, while maintaining the controller's functionality behind the display panel.

AI summary
An image display device (10) includes: an image display unit (100) which includes a display panel (110) switchable between an image display mode in which an image is displayed and a transmissive mode in which the display panel (110) is in a transmissive state where an object (500) behind the image display unit (100) is visible in a front view of the display panel (110); a controller (180) which controls an operation of the display panel (110); and a lower shelf board (160) which is a holding member. The lower shelf board (160) is disposed projecting rearward from a rear surface of the image display unit (100) and holds the controller (180) in a housed state.
