Transparent Display Driver Layout for Unobstructed Rear Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display devices with transparent displays have limited usability of the back side due to the placement of the drive circuit behind the display, restricting the use of the transparent display's rear area.
Innovation Solution
The image display device is configured with a display panel that can switch between transmissive modes, featuring a frame unit and driver placement that allows the back side of the display panel to be easily used, including an illumination unit to illuminate the rear area and a heat dissipator to manage heat generated by the driver, while the driver is supported by the frame unit to prevent visibility and facilitate object placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drive circuit is disposed behind the transparent display on the inner side relative to the lateral side of the showcase, then the drive circuit can be integrated into the display structure, but the usable range of the back side of the transparent display is limited
Solution Approach 1:
The drive circuit is repositioned from a horizontal placement behind the display to a vertical placement on the side surface of the showcase. This dimensional change allows the back side of the transparent display to be fully utilized while maintaining drive circuit integration through the side mounting structure
2Device complexity
If the drive circuit is placed behind the display panel, then the display structure is compact, but the back side of the display panel cannot be easily used for object placement
Solution Approach 1:
The drive circuit is extracted from the space behind the display panel and relocated to the side surface of the showcase. This extraction removes the obstruction from the back side area, enabling easy placement and viewing of objects while preserving the compact overall structure through efficient space utilization
3Ease of operation
If the drive circuit is positioned on the side surface of the showcase, then the back side of the display panel becomes accessible, but additional structural components are required
Solution Approach 1:
The side surface of the showcase serves multiple functions: it acts as both the mounting structure for the drive circuit and as part of the overall display housing. This multi-functionality eliminates the need for additional dedicated mounting brackets or supports, achieving back side accessibility without increasing structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the usability of the back side of the display panel by allowing objects to be placed and viewed without obstructing the driver, while maintaining the display's functionality and aesthetic appeal, and reduces the device's horizontal size by stacking circuit boards vertically.

AI summary
An image display device (10) according to the present disclosure includes: a display panel (12); a frame unit (14); and a driver (16). The display panel (12) is switchable between an image display mode in which an image is displayed and a transmissive mode in which the display panel (12) is in a transmissive state where an object (200) behind the display panel (12) is visible in a front view of the display panel (12). The frame unit (14) includes an upper plate (28) disposed along an upper edge of the display panel (12) and protruding rearward. The driver (16) includes a circuit unit (42) which drives the display panel (12). The driver (16) is supported by the upper plate (28) on a bottom side of the upper plate (28).
