Double-Sided Display Module Assembly for Compact Vehicle Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted display apparatuses lack efficient solutions for providing double-sided display capabilities while maintaining a compact and aesthetically pleasing design, especially in vehicles where space is limited and visibility for multiple passengers is essential.
Innovation Solution
A display assembly featuring a double-sided display module with a signal converter board, first and second display panels, and an encapsulation housing, where the display panels are arranged back-to-back and secured by connectors, allowing for flexible circuit board penetration and secure fixation, enabling double-sided display functionality without increasing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a double-sided display module is used to provide display capabilities on both sides, then visibility for multiple passengers is enhanced, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines two display modules (first display module and second display module) into a single integrated double-sided display module. The first display panel and second display panel are arranged back-to-back and fixed together through the encapsulation housing, merging two separate display functions into one unified structure that reduces overall device complexity while maintaining double-sided display capability
Solution Approach 2:
The encapsulation housing serves multiple functions simultaneously: it encloses and protects the display modules, fixes the first and second display modules together, provides mounting surfaces for connection portions, and enables both single-sided and double-sided display configurations. This multi-functional design simplifies the overall structure and reduces the number of separate components needed
2Volume of moving object
If display modules are arranged back-to-back to achieve double-sided display, then space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The connection portions (first connection portion and second connection portion) are designed to automatically align and self-fix the first display module and second display module when assembled. The connection portions engage with corresponding features on each display module, providing self-aligning and self-fixing functionality that reduces the need for high-precision manual alignment during assembly
Solution Approach 2:
The encapsulation housing is pre-formed with integrated connection portions that are positioned and configured before assembly. The connection portions are built into the housing structure in advance, establishing predetermined alignment references that guide the assembly process and reduce precision requirements during final assembly
3Strength
If an encapsulation housing with connection portions is used to fix display modules, then structural integrity is improved, but the number of components increases
Solution Approach 1:
The encapsulation housing integrates multiple functions into a single component: it encloses the display modules, provides structural support, and incorporates connection portions for mounting. By merging the housing and connection mechanisms into one integrated part, the design reduces the total number of separate components while maintaining structural integrity

AI summary
A display assembly includes a display device, a first clamping plate and a second clamping plate. The display apparatus has at least one display area, and the first clamping plate and the second clamping plate are disposed on two opposite sides of the display device in a thickness direction thereof. At least one of the first clamping plate and the second clamping plate is located on at least one light-emitting side of the display device, and in a clamping plate located on a light-emitting side of the display device, at least a partial region of a portion covering an active area of the display device is in a transparent state. The display device includes a double-sided display module including a first display module and a second display module that are arranged back to back and an encapsulation housing configured to fix the first display module and the second display module.
