Rotating Display Panel Radial Brightness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-dimensional displays using rotation technology suffer from poor viewing effects due to sparse and uneven voxel arrangements, resulting in varying brightness and frame frequencies that are not optimized for user experience.
Innovation Solution
A display panel with a rotation axis and multiple display sub-areas, each controlled by a driving-control module to adjust frame frequencies and brightness sequentially, ensuring imaging brightness is within a preset range, thereby improving the uniformity and quality of the displayed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If rotation displaying is used to create three-dimensional images, then spatial voxels are formed, but the voxels are sparse outside and dense inside resulting in dark outside and bright inside
Solution Approach 1:
The display panel divides the display area into multiple display sub-areas along the radial direction, with each sub-area having different display parameters (frame frequency, brightness) tailored to its specific position. This local differentiation compensates for the non-uniform voxel distribution, making the imaging brightness uniform across the entire display area.
Solution Approach 2:
The patent dynamically adjusts display parameters (frame frequency, brightness) for different display sub-areas based on their radial positions. By changing these parameters locally, the system compensates for the varying voxel densities and achieves uniform imaging brightness across the display area.
2Illumination intensity
If different display parameters are applied to different display sub-areas to compensate for brightness differences, then imaging brightness uniformity is improved, but the device complexity increases
Solution Approach 1:
The display area is segmented into multiple display sub-areas along the radial direction, with each sub-area controlled by a dedicated driving-control module. This segmentation enables independent parameter adjustment for each region while maintaining a manageable system architecture.
3Illumination intensity
If frame frequencies are increased for display sub-areas farther from the rotation axis, then imaging brightness is improved, but the energy consumption increases
Solution Approach 1:
The patent optimizes frame frequencies for different display sub-areas based on their radial positions and voxel densities. By adjusting parameters locally rather than uniformly increasing them, the system achieves brightness uniformity while minimizing overall energy consumption.

AI summary
A display panel, a display device and a method for driving the display panel. The display panel includes: a rotation axis; at least one display area located at one side of the rotation axis; wherein the display area includes a plurality of display sub-areas; and a plurality of driving-control modules corresponding to the plurality of display sub-areas. The plurality of display sub-areas are sequentially arranged along a first direction; the first direction is directed from the rotation axis to the display area; when the display panel rotates around the rotation axis, areas passed by the plurality of display sub-areas form a plurality of imaging sub-areas. The plurality of driving-control modules are configured to control the plurality of display sub-areas to have different display parameters, respectively, thereby enabling imaging brightness of the plurality of imaging sub-areas to be within a preset brightness range.
