Splice Display Optical Element for Seamless Narrow-Bezel Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with narrow bezels fail to achieve a true borderless display effect when spliced together, resulting in visible seams and a subpar display experience.
Innovation Solution
Incorporating a plano-convex optical element that amplifies the light exit angle in the sub-display region, allowing the frame region to match the display effect of the main display region, thereby creating a seamless borderless display when multiple devices are spliced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If narrow-bezel technology is used to reduce frame width, then the screen-to-body ratio is improved, but visible seams appear when devices are spliced together
Solution Approach 1:
The patent introduces an optical element as an intermediary component between the display panel and the viewer. This optical element specifically addresses the splice seam area by manipulating light paths to hide or eliminate the visual appearance of seams, thereby maintaining display uniformity across spliced devices without compromising the narrow-bezel design
Solution Approach 2:
The patent applies different optical properties to different regions of the display. The optical element is specifically positioned and configured to address the splice seam regions while leaving the main display areas unchanged. This localized approach allows the frame region to match the display effect of the main display region, eliminating visible seams at splice locations
2Ease of manufacture
If the frame region is made non-displaying to simplify structure, then manufacturing is easier, but the display effect becomes non-uniform when spliced
Solution Approach 1:
The patent makes the frame region multi-functional by enabling it to perform both structural support functions and display functions. The optical element allows the frame region to display images just like the main display region, creating a universal display surface across the entire device including previously non-displaying areas. This eliminates the need for separate handling of frame and display regions during splicing operations
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 solution enhances the display effect of spliced devices, improving their competitiveness and operational profit by eliminating visible seams and achieving uniformity with the main display region.
Implementation Method 1
an optical element disposed on the display panel and covers the sub-display region; wherein the optical element is configured to amplify a light exit angle of the light emitted, reflected or transmitted by the display panel of the sub-display region
