Display Panel Edge Shape Conversion and Luminance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may not be sufficiently satisfied with display apparatuses featuring round edges due to divided public preference, and existing technologies do not offer a flexible solution for changing the edge shape of display panels between rounded and flat states.
Innovation Solution
A display apparatus with a display panel that can selectively switch between a rounded and flat edge shape, utilizing a gate driver, data driver, and driving controller to manage pixel density and luminance compensation across different edge areas, and optionally incorporating a hinge or angle sensor for shape conversion and active/inactive state control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the edge area of the display panel is fixed in a rounded shape, then the design aesthetic and user grip are enhanced, but user satisfaction is limited due to divided public preference between round and flat edges
Solution Approach 1:
The display panel edge is designed to dynamically change shape between rounded and flat states. The edge area includes pixels that can be selectively activated or deactivated, and the physical shape can be transformed using hinges or flexible structures, allowing the display to adapt its edge geometry based on user preference or application requirements
Solution Approach 2:
The display panel is designed to perform multiple functions: it can operate with rounded edges for aesthetic appeal and grip enhancement, switch to flat edges for alternative user preferences, and selectively activate or deactivate pixel regions in the edge area. This multi-functionality resolves the contradiction by making a single device satisfy diverse user preferences
2Area of stationary object
If the edge area is converted to a flat state with active pixels, then the display area is increased, but luminance consistency and color coordination become more difficult to maintain
Solution Approach 1:
The display panel implements different pixel densities in different regions. The edge area (second display area) has a lower pixel density compared to the central display area (first display area). This local differentiation allows the edge area to be expanded while maintaining overall luminance consistency, as the luminance compensator can apply region-specific compensation values to achieve uniform appearance across areas with different pixel densities
Solution Approach 2:
A luminance compensator is implemented to measure and compensate for luminance differences across the display panel. The compensator adjusts the luminance output of different regions, including the expanded edge area, to maintain consistent overall luminance and color coordination across the entire display surface
3Use of energy by moving object
If the edge area pixels are deactivated in rounded state, then power consumption is reduced, but the display area is effectively decreased
Solution Approach 1:
The display panel dynamically adjusts its active display area based on the edge shape state. When in rounded state, the edge area pixels can be deactivated to save power. When switched to flat state, the edge area pixels are activated to expand the display area. This dynamic adjustment resolves the contradiction by allowing the system to optimize between power consumption and display area depending on the operational state

AI summary
A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel includes an edge area having a rounded shape in a first state and having a flat shape in a second state. The gate driver applies a gate signal to a gate line of the display panel, the data driver applies a data voltage to a data line of the display panel, and the driving controller processes input image data according to the first state and the second state. The display panel includes a first display area having a first pixel density and a second display area having a second pixel density less than the first pixel density. The second display area corresponds to the edge area of the display panel.
