Display Apparatus Multi-Layer Superimposition Resolution Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses struggle with effectively superimposing layers with different resolutions, leading to poor display effects and errors due to resolution differences, especially in applications like electronic whiteboards where touch trajectories and background patterns require precise alignment.
Innovation Solution
The display apparatus performs an interpolation operation on the touch trajectory pattern to match the resolution of the background pattern, ensuring that the superimposed result has consistent resolution, thereby eliminating aliasing and black edges, and improving the display effect by maintaining transparency and color accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If layers with different resolutions are directly superimposed, then the processing is simple and fast, but the display effect deteriorates with aliasing and black edges
Solution Approach 1:
The patent performs resolution adaptation (interpolation or downsampling) on the touch trajectory pattern before superimposition with the background pattern. This preliminary processing ensures that both layers have matching resolutions, eliminating aliasing and black edge artifacts while maintaining real-time display performance.
2Manufacturing precision
If resolution adaptation is performed on touch trajectory pattern, then the display quality is improved, but the processing complexity increases
Solution Approach 1:
The patent dynamically changes the resolution parameter of the touch trajectory pattern to match the background pattern's resolution. By adjusting the resolution parameter before superimposition, the system achieves high display quality without requiring complex processing architectures, as the adaptation is performed through standard interpolation or downsampling operations.
3Measurement precision
If the touch trajectory pattern resolution is changed, then the superimposition accuracy is improved, but the original touch trajectory detail may be lost
Solution Approach 1:
The patent performs resolution adaptation on the touch trajectory pattern before superimposition, ensuring that the resized pattern maintains alignment accuracy with the background pattern. By pre-processing the touch trajectory data to match the background resolution, the system achieves accurate superimposition while preserving essential touch trajectory information through appropriate interpolation methods.

AI summary
A display apparatus and a display method for a multi-layer superimposition are provided. When a display presents a user interface, a touch trajectory from a user can be detected via a touch component, and a touch trajectory pattern is present in a first layer; upon obtaining the touch trajectory pattern, an interpolation operation can also be performed on the touch trajectory pattern in the first layer according to a background pattern in a second layer; finally, a converted pattern obtained after the interpolation operation and the background pattern are superimposed and presented on the display.
