Prism Group Eliminates Non-Visible Area in Display Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display apparatuses have a non-visible area that reduces the overall visual experience due to the frame surrounding the display panel, which cannot be entirely eliminated by existing technologies.
Innovation Solution
A prism group comprising a first and second prism is disposed on the display module, where the first prism is on the visible area and the second prism is between the non-visible area and the platform of the first prism, guiding light rays from the visible area to emit from the non-visible area, effectively eliminating the non-visible area by refracting and reflecting light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a frame is used to assemble and fix the liquid crystal display panel and backlight module, then the display apparatus can be assembled and fixed, but the non-visible area surrounding the display panel cannot be entirely eliminated
Solution Approach 1:
The patent extracts the frame structure from the conventional display apparatus by eliminating the need for a surrounding frame through optical apparatus that extend to the edges of the display panel, thereby removing the non-visible area while maintaining assembly functionality
Solution Approach 2:
The optical apparatus are disposed to extend in the thickness direction from the display panel surface, utilizing the third dimension (depth) to provide structural support and optical functionality without requiring a surrounding frame in the planar dimensions
2Area of stationary object
If the width of the non-visible area is reduced, then the visual experience is improved, but the non-visible area still exists and cannot be completely eliminated
Solution Approach 1:
The patent converts the previously harmful non-visible area into a beneficial feature by using optical apparatus to guide light from the display panel through the non-visible area, transforming dead space into an additional display region that enhances visual experience
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
The prism group enables the elimination of the non-visible area, enhancing the overall visual experience by allowing light rays to be directed from the visible area to the non-visible area, thus improving the display's aesthetic and functional performance.
Implementation Method 1
The first prism is disposed on the visible area and has a main body and a platform connected to the main body. The main body has a first light incident surface, a first light emitting surface and a first inclined surface.
Implementation Method 2
The first inclined surface is connected between the first light incident surface and the first light emitting surface
Implementation Method 3
The second prism is disposed between the non-visible area and the platform, wherein the second prism has a second light incident surface, a second light emitting surface and a second inclined surface.
Implementation Method 4
The second inclined surface is connected between the second light incident surface and the second light emitting surface

AI summary
A prism group, configured to cover a portion of a visible area and a portion of a non-visible area of a display module, includes a first prism and a second prism. The first prism disposed on the visible area includes a main body and a platform. The main body has a first light incident surface, a first light emitting surface and a first inclined surface. The first light incident surface faces to the visible area. The first light emitting surface is nearby the non-visible area and connected to the first light incident surface. The first inclined surface is connected between the first light incident surface and the first light emitting surface. The platform is opposite to the non-visible area and connected to the first light emitting surface. The second prism is disposed between the non-visible area and the platform. A display device having the prism group is also provided.
