Image Compensation Element for Frameless Multi-Display Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and limited availability of large display devices for displaying big images necessitate the use of multiple smaller display devices and backlight modules to cooperatively display large images, while maintaining a frame-less appearance and ensuring uniform image quality.
Innovation Solution
The implementation of an image compensation element with a convex lens structure or light guiding channels in display devices, which extends and amplifies the image from the periphery display region to a non-display region, creating a seamless and larger image display without a visible frame, and a backlight module with varying light intensity distribution to ensure uniform image brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple smaller display devices are used to cooperatively display large images, then the cost is reduced and availability is improved, but the image definition and uniformity deteriorate
Solution Approach 1:
The display system is divided into multiple independent display devices, each displaying a portion of the overall image. The image compensation element is also segmented into multiple units that can be independently manufactured and then assembled together, allowing each unit to be produced with standard manufacturing precision while achieving a large-scale display system.
Solution Approach 2:
The image compensation element acts as an intermediary between the display element and the viewer. It compensates for the discontinuities and definition losses at the boundaries between multiple display devices by extending images from display regions into non-display regions, creating a seamless visual experience that masks the segmented nature of the system.
2Ease of manufacture
If multiple smaller display devices are used to cooperatively display large images, then the cost is reduced and availability is improved, but the frame-less appearance and uniform brightness deteriorate
Solution Approach 1:
The image compensation element has different optical properties in different regions. The convex lens structure or light guiding channels are strategically positioned to provide different compensation effects for different display regions, ensuring that boundary regions receive enhanced compensation to match the central regions, thereby achieving uniform overall appearance.
Solution Approach 2:
The backlight module employs varying light intensity distribution across different regions. By adjusting the luminance parameters of the backlight in different zones, the system compensates for variations in image brightness that occur when multiple display devices are assembled, ensuring uniform perceived brightness across the entire display area.
3Shape
If an image compensation element with convex lens structure is added, then the image extension and frame-less appearance are improved, but the device complexity increases
Solution Approach 1:
The image compensation element is integrated with the display element and backlight module into a unified assembly. The convex lens structure or light guiding channels are incorporated into the existing display structure rather than being added as separate components, reducing overall system complexity while achieving the frame-less appearance effect.
4Illumination intensity
If a backlight module with varying light intensity distribution is implemented, then the uniform brightness is improved, but the device complexity increases
Solution Approach 1:
The backlight module uses variations in light source intensity parameters across different regions rather than complex mechanical or electronic control systems. By designing the backlight with inherently different luminance characteristics in different zones, the system achieves uniform overall brightness through simple parameter optimization rather than complex active control mechanisms.

AI summary
A display device includes a display element, an image compensation element, and a backlight module. The display element includes a main display region and a periphery display region located at one side of the main display region, each of the main display region and the periphery display region includes a plurality of pixels. The image compensation element includes a compensation portion corresponding to the periphery display region, and the image compensation element extends an image of the periphery display region to one side of the periphery display region away from the main display region. The backlight module provides first light beams to the main display region and second light beams to the periphery display region, and an intensity of the first light beams is smaller than an intensity of the second light beams.
