Splicing Screen Color Gamut Matching at Display Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional splicing screens suffer from uneven screen images due to differences in color gamut between display panels at splicing slits, leading to a poor display effect.
Innovation Solution
A splicing screen design that includes a first and second display panel of the same type, with a third display panel of a different type sandwiched between them, featuring a color gamut adjustment module on second light emitting modules to match the color gamut of the first light emitting modules, ensuring consistent light emission across panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If display screens of different types are used at splicing slits to eliminate slits, then the splicing slit visibility is reduced, but the color gamut uniformity deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting the color gamut of the third display panel (sandwiched at splicing slits) to match the color gamut parameters of the first and second display panels. This is achieved by modifying the light emitting characteristics of the third display panel, ensuring that its color gamut falls within the same range as the adjacent panels, thereby resolving the color gamut uniformity issue while maintaining slit elimination
Solution Approach 2:
The patent applies local quality by treating the third display panel at the splicing slit location differently from the main display panels. While the third panel is of a different type (with different structure or material), its color gamut is specifically adjusted to match the local requirements of the surrounding panels, creating a localized adaptation that ensures overall uniformity
2Area of stationary object
If display screens are spliced to achieve greater size, then the display area increases, but splicing slits appear affecting display effect
Solution Approach 1:
The patent applies the intermediary principle by introducing a third display panel as a mediator at the splicing slit locations. This third panel is positioned between the first and second display panels and is configured to emit light that matches the color gamut of the adjacent panels, thereby mediating the visual transition at the splice and making the slits imperceptible
Solution Approach 2:
The patent applies copying by making the third display panel at the splicing slit replicate the color gamut characteristics of the first and second display panels. Although the third panel may have different internal structure, it copies the essential visual output characteristics (color gamut) to ensure seamless integration with the surrounding display area
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 solution prevents abnormal screen images at splicing slits by aligning the color gamuts of different display panels, thereby improving the overall display effect.
Implementation Method 1
a first light emitting module is disposed on the first substrate; the third display panel comprises a second substrate, a plurality of second light emitting modules are disposed on the second substrate
Implementation Method 2
a color gamut adjustment module is disposed on at least one of the second light emitting modules, and the color gamut adjustment module is configured to adjust color gamuts of the second light emitting modules
Data Source
AI summary
The present application provides a splicing screen and a display device. The display screen comprises at least a first display panel and a second display panel of a same type, and a third display panel with a type different from that of the first display panel and sandwiched between the first display panel and the second display panel. Each of the first display panel and the second display panel comprises the first light emitting module. The third display panel comprises a plurality of second light emitting modules. A color gamut adjustment module is disposed on at least one of the second light emitting modules such that a color gamut of the third light emitting module is the same as a color gamut of the first light emitting module to further make light emitted by the first display panel, the second display panel, and the third display panel similar.
