Stretchable Display Adaptive Resolution Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stretchable display apparatuses face challenges in maintaining image quality and resolution when transformed or expanded, as they struggle to adapt image rendering based on the degree of expansion, leading to inconsistent viewer experience.
Innovation Solution
A stretchable display apparatus with a display control method that determines the degree of expansion and adjusts the display mode between a first and second resolution by classifying pixels into groups, allowing for adaptive image signal output based on expansion levels in different directions, thereby maintaining consistent image quality and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display apparatus is expanded or stretched to increase display area, then the display size increases, but the image quality and resolution deteriorate
Solution Approach 1:
The patent implements dynamic resolution adjustment based on the expansion state of the display apparatus. The controller detects the degree of expansion and automatically switches between different display modes (first mode with higher resolution for non-expanded state, second mode with lower resolution for expanded state), making the resolution adaptive to the physical state of the display
Solution Approach 2:
The patent changes the display parameter (resolution) based on the expansion state. By detecting the expansion degree and adjusting the resolution parameter accordingly, the system maintains acceptable image quality across different display areas, transforming the static resolution into a dynamic parameter that adapts to physical changes
2Area of stationary object
If the display apparatus is expanded to provide larger display, then the display size increases, but power consumption increases
Solution Approach 1:
When the display apparatus is expanded, the patent activates only a portion of the pixels (second mode with lower resolution) rather than all pixels, reducing power consumption. This partial action principle allows the display to function adequately in expanded state without requiring full pixel activation, thereby saving energy while maintaining display functionality
3Adaptability or versatility
If the display apparatus transforms into various forms, then the adaptability increases, but the image consistency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the controller continuously monitors the expansion state of the display apparatus and adjusts the display mode accordingly. This closed-loop control ensures that the display automatically adapts to maintain consistent image quality across different forms, with the expansion state serving as feedback input for resolution adjustment

AI summary
A display control method of a stretchable display apparatus includes determining a degree of expansion of the display apparatus, and controlling a display mode of the display apparatus to be a first mode or a second mode based on the degree of expansion. A first resolution is embodied in the first mode by transmitting a data signal to each of pixel groups formed by classifying a plurality of pixels into the pixel groups. A second resolution is embodied in the second mode by transmitting a data signal to each of the plurality of pixels.
