Flexible Display Gamma Voltage Adjustment for Deformation Luminance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face issues with maintaining desired luminance and reducing power consumption when partially deformed, as driving only a partial region of the display panel can lead to increased luminance and inefficient power use.
Innovation Solution
A flexible display device that includes a flexible display panel with stored entire and partial driving gamma data, a gamma reference voltage generator that adjusts based on deformation state, and a data driver that provides voltages based on generated gamma reference voltages, ensuring consistent luminance and reduced power consumption by interpolating gamma data as the panel deforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If only a partial region of the display panel is driven to reduce power consumption, then power consumption is reduced, but luminance increases undesirably
Solution Approach 1:
The patent applies parameter changes by adjusting the gamma reference voltage based on the deformation state of the flexible display panel. When the panel is deformed and only a partial region is driven, the system changes the gamma reference voltage parameter to compensate for the increased luminance, thereby maintaining desired display quality while keeping power consumption low.
2Illumination intensity
If the entire display panel is driven to maintain desired luminance, then luminance is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamics by making the gamma reference voltage adjustable based on the deformation state. The system dynamically switches between different gamma reference voltage settings depending on whether the flexible display panel is in a deformed or non-deformed state, allowing optimal power consumption while maintaining desired luminance characteristics.
3Illumination intensity
If gamma reference voltage is adjusted for partial driving, then luminance is controlled, but display quality may deteriorate
Solution Approach 1:
The patent applies feedback by using deformation information about the flexible display panel to adjust the gamma reference voltage. The system receives feedback on the panel's deformation state and accordingly modifies the gamma reference voltage to maintain consistent display quality across different deformation conditions, preventing deterioration of display quality.
