Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in improving resolution and image quality, particularly in maintaining effective pixel density and reducing the screen door effect.
Innovation Solution
The display device incorporates a panel moving unit that moves the display panel in a reciprocating motion, allowing for improved pixel density and reduced non-emission areas, enhancing resolution and image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display panel uses a fixed pixel arrangement, then the manufacturing process is simple, but the resolution and image quality are limited
Solution Approach 1:
The patent applies the dynamics principle by making the display panel movable rather than fixed. The panel moving unit enables the display panel to reciprocate between a first position and a second position, transforming the static display structure into a dynamic one. This allows the same physical pixels to cover different display areas at different times, effectively increasing resolution without requiring more physical pixels or complex manufacturing processes
2Manufacturing precision
If the pixel density is increased to improve resolution, then the image quality improves, but the screen door effect becomes more noticeable
Solution Approach 1:
The patent applies the dimensionality change principle by adding the time dimension to the display process. Instead of simply increasing pixel density in the spatial domain, the system uses temporal movement to effectively increase the number of displayable pixels. The panel moves between positions during different time periods, allowing pixels to occupy different spatial locations at different times, thereby reducing the screen door effect without requiring extremely high spatial pixel density
3Measurement precision
If the display panel is made movable to increase effective resolution, then the resolution improves, but the device complexity increases
Solution Approach 1:
The patent applies the segmentation principle by dividing the frame period into multiple sub-frame periods. The panel moves to different positions during different sub-frame periods, and the controller manages pixel activation accordingly. This temporal segmentation allows the system to achieve higher effective resolution by displaying different pixel subsets at different positions and times, while keeping the physical panel structure relatively simple

AI summary
A display device has a display panel including a plurality of pixels connected to scan lines extending in a first direction and data lines extending in a second direction different from the first direction (DR1, DR2) and a panel moving unit for reciprocating the display panel in a third direction with respect to the first direction and the second direction (DRD). Each of the plurality of pixels includes a plurality of subpixels (EA1, EA2) arranged in a sub-sampled structure.
