Translucent Display Region Pixel Density for Under-Display Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a light sensor into display panels for full-screen displays is hindered by the need for non-display slots or holes, which reduces the screen-to-body ratio and affects the display integrity, as existing solutions cannot effectively arrange the light sensor under the display area while maintaining high transmittance and display quality.
Innovation Solution
A display panel design incorporating a conventional display region and a translucent display region with varying pixel densities and colors, allowing the light sensor to be positioned under the display area, where the translucent region has reduced pixel density to enhance transmittance and maintain display fineness by using sub-pixels with specific densities and arrangements to match the conventional display region's brightness and color ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-display slot or hole is provided in the display panel for arranging the light sensor, then the light sensor can be arranged under the display area, but the screen-to-body ratio is reduced and display integrity is affected
Solution Approach 1:
The display panel is divided into two regions with different properties: a conventional display region with normal pixel density and a translucent display region with reduced pixel density. This local differentiation allows the translucent region to transmit light for sensor placement while the conventional region maintains normal display function, resolving the contradiction between sensor arrangement and screen-to-body ratio.
2Illumination intensity
If the pixel density is reduced in the translucent display region to enhance light transmittance, then the light sensor can be positioned under the display area, but the display fineness may be compromised
Solution Approach 1:
Different pixel densities are applied to different regions: the translucent display region uses reduced pixel density to maximize light transmittance for sensor operation, while the conventional display region maintains high pixel density for fine display quality. This spatial differentiation of quality parameters resolves the contradiction between transmittance and display fineness.
Solution Approach 2:
The display panel is segmented into functionally distinct regions: a translucent display region optimized for light transmission and a conventional display region optimized for visual output. This segmentation allows each region to be optimized for its specific function without compromising the other, enabling both high transmittance and fine display quality in their respective zones.
3Stability of the object's composition
If sub-pixels with specific densities and arrangements are used to match the conventional display region's brightness and color ratios, then display quality consistency is maintained, but the device complexity increases
Solution Approach 1:
The patent adjusts pixel density as a key parameter in the translucent display region compared to the conventional region. By changing this physical parameter and compensating through algorithmic brightness and color ratio adjustments, the system maintains display quality consistency across regions while managing complexity through parameter optimization rather than structural complexity.
