Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face limitations in increasing resolution due to pixel aperture ratio and circuit constraints, and existing methods like PenTile arrangement only allow limited improvement in display effect beyond a certain resolution.
Innovation Solution
A display method that generates multiple images with the same boundaries as the original image, displaying them as continuous multi-frame images within the visual persistence time of human eyes, ensuring all information is conveyed, even if the original image's resolution is higher than the display device, thereby enhancing the display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display device is increased by adding more pixels, then the display definition is improved, but it becomes more difficult to prepare more pixel points due to aperture ratio and circuit limitations
Solution Approach 1:
The invention segments the original image into multiple first images, each containing partial information. By displaying these segmented images in sequence within visual persistence time, the system achieves higher effective resolution without adding physical pixels to the display panel.
Solution Approach 2:
The invention transitions from spatial resolution enhancement (adding pixels in 2D space) to temporal resolution enhancement (displaying multiple images over time). This dimensional shift allows resolution improvement without being constrained by physical pixel density limits.
2Measurement precision
If the PenTile arrangement mode is used to share pixels between adjacent pixel points, then the number of pixel points is increased, but only one pixel can be shared between two adjacent pixel points which limits further improvement
Solution Approach 1:
Instead of sharing individual pixels between adjacent pixel points, the invention segments the entire image into multiple first images. Each pixel in the display device can participate in representing multiple different pixel points across different frames, greatly enhancing pixel utilization flexibility.
Solution Approach 2:
The invention changes the temporal parameter by displaying images at different time points within visual persistence time. This allows the same physical pixels to represent different logical pixel points at different moments, effectively increasing the number of usable pixel points beyond the physical pixel count.
3Measurement precision
If multiple first images are generated and displayed in sequence within visual persistence time, then the observed resolution and information are increased, but the processing complexity increases
Solution Approach 1:
The original image is segmented into multiple first images with different resolutions or information densities. This segmentation allows the display system to present enhanced resolution information over time while keeping each individual frame manageable in size and processing requirements.
Solution Approach 2:
Instead of requiring complex real-time processing to generate high-resolution images, the system creates multiple copies (first images) with varying information content and displays them in sequence. The visual persistence effect combines these copies to produce the perception of higher resolution, reducing computational complexity.

AI summary
The present invention relates to a display method and a display device. The display method includes steps of: S1, obtaining an original image that needs to be displayed; S2, generating a plurality of first images each having the same boundary as the original image according to the information contained in the original image, wherein each first image includes at least partial information of the original image, and union of information contained in the plurality of first images includes all information contained in the original image; and S3, displaying, in the form of continuous multi-frame images, all first images in sequence within visual persistence time of human eyes. The above method can improve the display effect of the display device.
