Transparent Display Panel Brightness Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent display panels suffer from suboptimal display effects due to environmental interference, particularly when background regions with high or low brightness values are present, adversely affecting user experience.
Innovation Solution
An image display method that acquires an environmental image in the backlight direction of the display panel, determines the user's viewing position and background image, and adjusts image compensation parameters to optimize the display by adjusting driving currents based on grayscale parameters, ensuring clear viewing of both background and original content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display panel is used to enable users to view the environment in the backlight direction, then the transparency and environmental visibility are improved, but the display quality deteriorates when background regions with high or low brightness values are present
Solution Approach 1:
The patent applies local quality by dividing the display panel into multiple regions and applying different compensation parameters to each region based on its specific background brightness characteristics. The processing module determines different image compensation parameters for different regions of the display panel, allowing each region to be optimized independently for its local environmental conditions, thereby resolving the contradiction between maintaining transparency and ensuring display quality across varying background brightness levels.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting image compensation parameters (such as gamma correction values, brightness offsets, or contrast factors) based on the detected background brightness values. The processing module modifies display parameters in real-time according to environmental conditions captured by the imaging device, enabling the display panel to adapt its characteristics to match the surrounding environment and maintain optimal display quality while preserving transparency.
2Manufacturing precision
If the display panel compensates for regions with high or low brightness values to improve display quality, then the display quality is improved, but the complexity of the control system increases
Solution Approach 1:
The patent applies universality by designing a control system that performs multiple functions: the imaging device both captures environmental images and provides data for compensation calculations, the processing module both analyzes background brightness and generates compensation parameters, and the same system components operate across different display regions and various brightness conditions. This multi-functional approach reduces overall system complexity by avoiding separate dedicated components for each function.
Solution Approach 2:
The patent implements self-service by enabling the display system to automatically detect environmental conditions, calculate appropriate compensation parameters, and adjust its own display characteristics without external intervention. The processing module autonomously analyzes the environmental image data and generates compensation parameters based on predefined algorithms, eliminating the need for manual calibration or complex external control systems while maintaining high display quality.
