Splice Display with Transparent OLED Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-area splice displays with multiple small-area liquid crystal displays (LCDs) suffer from visible frames that affect image quality and viewer comfort, as existing solutions cannot fully eliminate these frames.
Innovation Solution
A splice display configuration using at least two mutually spliced LCDs with a transparent organic electroluminescence display (OLED) frame that covers the spliced frames, accompanied by an image splitter, color calibrator, and brightness calibrator to ensure consistent color saturation and uniform brightness across all zones, eliminating the need for visible frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple small-area LCDs are spliced to form a large-area display, then the display area is increased, but visible frames appear at spliced positions affecting image quality
Solution Approach 1:
An OLED component is introduced as an intermediary element to cover the spliced frames between LCD modules. The OLED acts as a mediator that fills the gap caused by LCD frames, allowing the frameless benefit to be achieved while maintaining the large-area display capability of multiple spliced LCDs
Solution Approach 2:
The patent merges LCD and OLED technologies in a hybrid display system. LCD modules provide the main display area while OLED components fill the spliced frame regions, creating a unified frameless display effect by combining the advantages of both display technologies
2Object-affected harmful factors
If LCD frames are made narrower to reduce visibility, then the frame impact is reduced, but the frames cannot be fully removed
Solution Approach 1:
Rather than continuously reducing LCD frame widths, the patent introduces OLED as an intermediary that completely covers the frame region. This approach bypasses the manufacturing precision challenges of making ultra-narrow frames by using a separate component to mask the frames entirely
3Object-affected harmful factors
If a transparent OLED frame is used to cover spliced frames, then frame visibility is eliminated, but color saturation consistency between LCD and OLED becomes problematic
Solution Approach 1:
A color calibrator is introduced to dynamically adjust display parameters of the OLED component. By changing parameters such as brightness, contrast, and color saturation through software control, the system achieves color consistency between LCD and OLED regions, eliminating the need for precise manufacturing matching
4Object-affected harmful factors
If OLED is used to cover spliced frames, then seamless display is achieved, but brightness uniformity across different zones becomes inconsistent
Solution Approach 1:
The brightness calibrator adjusts the brightness parameter of the OLED component dynamically to match the surrounding LCD zones. By changing display parameters in real-time, the system achieves uniform brightness across all zones including the previously framed areas, eliminating brightness inconsistencies

Function Achieved in This Case
The solution allows for a seamless, high-quality image display without visible frames, improving viewer comfort and simplifying OLED manufacturing by requiring only a thin, transparent OLED frame that does not interfere with the LCD display.
Implementation Method 1
at least one organic electroluminescence display (OLED). A frame of the OLED is transparent, the OLED covers the spliced frame
Implementation Method 2

Data Source
AI summary
A splice display includes at least two liquid crystal displays (LCDs) that are mutually spliced, and the LCDs form a spliced frame at a spliced position of the LCD. The splice display further includes an image splitter and at least one organic electroluminescence display (OLED) panel. A frame of the OLED is transparent, and the OLED covers the spliced frame. The image splitter splits an image signal into a plurality of parts, and transmits the split image signal to the OLED and the LCDs for display.
