Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to efficiently adapt and display images on deformed flexible panels, such as those that can be curved, bent, or rolled, while maintaining image quality and requiring minimal additional space for deformation detection.
Innovation Solution
Integration of a detector, such as an acceleration sensor, gyro sensor, or geomagnetic sensor, into a flexible printed circuit board (FPCB) within the display device to detect deformation and control the application of data signals only to selected pixels, allowing the display to adjust its image area accordingly, along with a rotator and printed circuit board to manage the display panel's deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is deformed (curved, bent, or rolled), then the display device can adapt to different form factors and usage scenarios, but the image display quality and pixel selection become difficult to control
Solution Approach 1:
The patent incorporates sensors (acceleration sensors, gyro sensors, or geomagnetic sensors) that detect the deformation state of the flexible display panel and provide feedback signals to a controller. The controller then adjusts pixel selection and data signal application based on the detected deformation, enabling real-time adaptation while maintaining display quality.
2Difficulty of detecting and measuring
If deformation detection components are added to the display device, then the ability to detect and adapt to panel deformation is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent integrates the deformation detection function into existing structural components of the display device. The detector is incorporated into the driver, which itself is integrated into the flexible printed circuit board (FPCB). This merging approach allows deformation detection without adding separate, complex detection systems.
Solution Approach 2:
The driver component performs multiple functions: it drives the display pixels and simultaneously houses the deformation detector. This multi-functionality reduces the overall device complexity by eliminating the need for separate dedicated detection modules.
3Area of stationary object
If data signals are applied to all pixels, then complete image coverage is achieved, but energy consumption increases when only part of the display area is needed
Solution Approach 1:
The patent applies data signals only to the necessary subset of pixels based on the detected deformation state. Instead of driving all pixels continuously, the system selectively activates only those pixels required for the current display area, reducing energy consumption while maintaining adequate image coverage.
