Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies with under-screen cameras face challenges in improving the display effect and imaging quality of the camera region, as the camera opening restricts the screen-to-body ratio and affects light transmission.
Innovation Solution
A display panel design featuring multiple light transmitting regions and a display region, where the light transmitting regions include sub-regions with functional parts arranged in a complementary manner to enhance light transmittance and imaging capabilities, while maintaining display functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera opening is provided in the display panel, then the under-screen camera can transmit light for imaging, but the screen-to-body ratio is reduced and light transmission is affected
Solution Approach 1:
The display panel is segmented into multiple light transmitting regions and display regions. Each light transmitting region contains multiple pixel units with functional parts arranged in complementary patterns, allowing light transmission while maintaining display functionality in other regions.
Solution Approach 2:
Different regions of the display panel are assigned different functions: some regions are optimized for light transmission (light transmitting regions) while others are optimized for display (display regions). Within light transmitting regions, pixel units have functional parts arranged specifically to enhance light transmittance for imaging.
2Adaptability or versatility
If pixel units are arranged in the light transmitting region, then display functionality is maintained, but light blocking increases and imaging quality deteriorates
Solution Approach 1:
Pixel units in light transmitting regions have functional parts (such as transparent conductive materials or optical elements) arranged in specific patterns that prioritize light transmission. The functional parts are positioned to minimize light blocking while maintaining electrical connectivity for display operation.
Solution Approach 2:
Each pixel unit is segmented into functional parts with specific optical properties. The functional parts are arranged in complementary patterns across multiple pixel units, creating regions of high light transmittance that facilitate imaging while maintaining display capability through the remaining structures.
3Measurement precision
If functional parts are arranged in complementary patterns, then light transmittance is enhanced, but the structural complexity increases
Solution Approach 1:
The complex arrangement of functional parts is broken down into modular pixel units, each containing simplified functional structures. These modular units are then arranged in complementary patterns across the display panel, allowing complex overall light transmission optimization through repeated simple structures.
Solution Approach 2:
The complementary arrangement of functional parts utilizes spatial positioning in multiple dimensions. By varying the position and orientation of functional parts across different pixel units in a systematic pattern, the design achieves enhanced light transmittance through geometric arrangement rather than complex material structures.
